&lt;div&gt;=Remote Collaboration Options=&lt;br /&gt;
&lt;br /&gt;
There are many ways that one can participate in the development of the Global Village Construction Set ([[GVCS]]) remotely.There are 40 technologies. For these we need:&lt;br /&gt;
* &#039;&#039;&#039;Webmaster&#039;&#039;&#039; - with the caveat that the person has to assure continuity of their work. Clear presentation is necessary to get beyond the present disorganization on our internet presence.&lt;br /&gt;
* &#039;&#039;&#039;Designs, CAD, and prototypes&#039;&#039;&#039;. Most are flexible fabrication equipment items and heavy equipment items, plus agriculture and energy production items.&lt;br /&gt;
* Publicity work]&lt;br /&gt;
* &amp;lt;span style=&amp;quot;color:red&amp;quot;&amp;gt;Architectural drawings for CEB construction - priority for [[Solar Village 2010]]&lt;br /&gt;
* Assistance in &#039;&#039;&#039;power electronics&#039;&#039;&#039; for an induction furnace and a universal electrical power source,&lt;br /&gt;
* Organizational help in producing a 10-15 minute powerful video on our message. &lt;br /&gt;
* People to organize &#039;&#039;&#039;speaking and lecture tours&#039;&#039;&#039;&lt;br /&gt;
* People to produce and submit &#039;&#039;&#039;articles&#039;&#039;&#039; to different media venues&lt;br /&gt;
* People to produce a detailed agricultural open source agroecology plan for our facility. &lt;br /&gt;
* We also need visualization modeling for our facility and program&lt;br /&gt;
* People to write &#039;&#039;&#039;diagramming software&#039;&#039;&#039; (see the [[#Computer Support]] section)&lt;br /&gt;
* People to produce 3D CAD modules for Blender or fork thereof&lt;br /&gt;
* Alternatively help in the &#039;&#039;&#039;development of a 3D CAD solution&#039;&#039;&#039; (see the [[#Computer Support]] section)&lt;br /&gt;
* We need to organize a well thought out campaign for recruiting [[True Fans]].&lt;br /&gt;
* We need somebody to write a &#039;&#039;&#039;survey course on power electronics&#039;&#039;&#039;, which is the next untapped frontier related to the Global Village Construction Set. &lt;br /&gt;
* We need to produce a Product Release CD for The Liberator, but that is primarily work to be done on site with the machine at hand.&lt;br /&gt;
&lt;br /&gt;
=Organizational Development=&lt;br /&gt;
&lt;br /&gt;
The organizational development component lends itself especially well to remote collaboration - because it can produce substantial resources for our operation, and it can certainly be done from anywhere in the world where someone has access to a computer and phone.&lt;br /&gt;
&lt;br /&gt;
There is a large list of organizational tasks that need doing, from writing articles for submission, contacting publishers of magazines to feature our work, soliciting collaboration with allied groups, organizing lecture and speaking tours, producing publicity materials, organizing the wiki into a coherent whole, developing a workable social contract for resilient communities, and developing a network of collaborators and developers - among countless other tasks. &lt;br /&gt;
&lt;br /&gt;
The key to this is clear communications. Someone interested in doing this needs to have good marketing skills, as well as good writing and technical writing skills. The best person for this job is an actual stakeholder - one who understands our work sufficiently to the point of living by our principles - such that this stakeholder is in a good position to explain the nuances of our work to others.&lt;br /&gt;
&lt;br /&gt;
=Computer Support=&lt;br /&gt;
We need:&lt;br /&gt;
* Somebody to run &#039;&#039;&#039;regular backups&#039;&#039;&#039; of the wiki and blog&lt;br /&gt;
* &#039;&#039;&#039;An Open Source 3D CAD&#039;&#039;&#039; program.&amp;lt;br /&amp;gt;We currently use Blender, but for real engineering tasks, a Solidworks equivalent would be much better. [http://sourceforge.net/apps/mediawiki/free-cad/index.php?title=Main_Page FreeCAD] seems to be the most promising one, &#039;&#039;&#039;contribute to it&#039;&#039;&#039;. For example with a script that implements exploded parts diagrams.&lt;br /&gt;
* &#039;&#039;&#039;An Open Source diagramming application&#039;&#039;&#039;.&amp;lt;br /&amp;gt;We currently use Dia, but it could be better and it is currently not actively developed. A possibility would be to port Kivio to KOffice2, which should be pretty easy using the powerful KOffice2 libraries. &lt;br /&gt;
* In the meantime, for more official documents a &#039;&#039;&#039;task&#039;&#039;&#039; could be to recreate a &#039;&#039;&#039;high quality version&#039;&#039;&#039; of the dia diagrams with &#039;&#039;&#039;Inkscape&#039;&#039;&#039;. Here are some [http://www.ioncannon.net/utilities/123/10-tips-for-creating-good-looking-diagrams-using-inkscape/ tips] and [http://apachelog.files.wordpress.com/2010/08/ubuntuone-kde-graph3.png an example].&lt;br /&gt;
* Somebody to produce a &#039;&#039;&#039;more complete set of icons for the OS Tech [[Pattern Language]]&#039;&#039;&#039;, including not only the 40 technologies but various components.&amp;lt;br /&amp;gt;The goal of this is to do pictorial design of tools, objects, houses, agriculture landscapes, facilities, and communities. For example, a tree or a bolt icon is ever useful.&lt;br /&gt;
* Design of a functional, &#039;&#039;&#039;dynamic content management system for the OSE project&#039;&#039;&#039;, focusing on the specific needs of OSE&#039;s [[GVCS]] development.&amp;lt;br /&amp;gt;This system should embody the essential features a scalable, open source product development methodology such as suggested at [[Open Source Economic Development Method]].&lt;br /&gt;
* &#039;&#039;&#039;Help in the development of 3D animations&#039;&#039;&#039; by collecting useful, open repositories of objects that can be then processed in [[Blender]]. [http://openfarmtech.org/index.php/Money_as_Debt_II:_Promises_Unleashed This is an example] of taking existing 3D material to make a movie.&lt;br /&gt;
&lt;br /&gt;
Basically, any open source technology that is not readily available yet should be documented and opensourced. Use this wiki and then move on to [[Open+Pario]] for technical development. See updates on the [http://blog.opensourceecology.org/ blog].&lt;br /&gt;
&lt;br /&gt;
=Power Electronics=&lt;br /&gt;
Power electronics is one of the as-of-yet untapped frontiers for Open Source Ecology. Our approach to this involves generating a [[Crash Course on Power Electronics]], at the same time as we build applications in collaboration with the greater open source hardware community. Applications include items such as the [[Induction Furnace]], for real-world needs at [[Factor e Farm]]&lt;br /&gt;
&lt;br /&gt;
Thus, we are looking for people to collaborate on creating the Crash Course, and to help in the actual designs/builds of power devices.&lt;br /&gt;
&lt;br /&gt;
While power electronics might sound like an abstract topic - it is one of the foundations of modern civilization. If you use electricity, you are using power electronics.  If you ever used a portable generator - you were using power electronics. If you ever used a welder, you were using power electronics. If you ever drive a car - you are using power electronics - for the charging of the car battery. Power electronics are all around us. Open-sourcing power electronics out of the hands of the priesthood that currently controls them - is one of the active interests of OSE.&lt;br /&gt;
&lt;br /&gt;

== Joining the Steam Engine Team==&lt;br /&gt;
&lt;br /&gt;
OSE policies on GVCS projects specify that only active, contributing people are considered part of the project team.  While we are always looking for people to help out, we need people who are committed to making real contributions.  We do not need people who want to talk about building steam engines, we need people who want to design and actually build them.  If you are such a person, please fill out the [[Team Culturing Survey]] and get yourself set up with accounts on the forum and wiki.  All Steam Engine documentation is publicly posted on the OSE wiki.&lt;br /&gt;
&lt;br /&gt;
After joining OSE, have a look at [[Steam Engine/Things To Do]] and the Steam Engine Pivotal Project [https://www.pivotaltracker.com/projects/300681#].  Pivotal is a project management tool that allows us to track tasks that need to be done. Figure out what you are interested and what matches your skills and experiences.  Then get in touch with the Steam Engine Project Manager (Mark Norton - markjnorton (at) earthlink (dot) net).&lt;br /&gt;
&lt;br /&gt;
You will be given one or two tasks to complete before being invited as a full project participant.  To some degree, this is a test of your commitment.  More than that, it is a way of building trust in your ability to make a meaningful contribution.  OSE GVCS Project teams are deliberately lean and agile.  The pace can be fast at times and we need you to adapt to the current rate of development.&lt;br /&gt;

&lt;div&gt;[[File:500px-Thermoelectric Generator Diagram.svg.png|thumb|right|A thermoelectric circuit composed of materials of different [https://en.wikipedia.org/wiki/Seebeck_effect Seebeck] coefficient (p-doped and n-doped semiconductors), configured as a thermoelectric generator.]]&lt;br /&gt;
&lt;br /&gt;
== Thermoelectric (TE) effect ==&lt;br /&gt;
Thermoelectric materials generate power directly from heat by converting temperature differences into electric voltage. A thermoelectric module is a circuit containing thermoelectric materials that generate electricity from heat directly. It consists of two dissimilar thermoelectric materials joining in their ends: an n-type (negatively charged); and a p-type (positively charged) semiconductors. &lt;br /&gt;
&lt;br /&gt;
== TE devices - characteristics ==&lt;br /&gt;
* This can potentially be very inexpensive if low-cost TE generators can be fabricated. &lt;br /&gt;
* TE generators have great potential for reliable conversion of heat to electricity. For example: [http://www.tegpower.com/ TEG Power Info] lists a 50 Watt 12V unit. If you get 20 and hook them up to a [[gasifier]] then you have something that can do useful work. It has one moving part. Which is a small easily replaceable cooling pump. These will last 20+ years and &#039;&#039;&#039;reliably&#039;&#039;&#039; produce power.&lt;br /&gt;
&lt;br /&gt;
==Marcin Comment==&lt;br /&gt;
This is excellent. Do you have practical experience with these? Can you lead a design effort to produce a robust, replicable TEG system? The heat sinking and packaging issues are not trivial in terms of making lifetime design systems, so that is why we have stayed away from these. Are you familiar with how to manufacture these? That would be very valuable information for resilient community enterprise.&lt;br /&gt;
&lt;br /&gt;

&amp;lt;/html&amp;gt;&lt;br /&gt;
&lt;br /&gt;
== Applications and Product Ecology ==&lt;br /&gt;
* this concept works on the temperature differential. Therefore, not just heat but also cooling is often required, so that the &amp;quot;cool&amp;quot; side of the device does not overheat, erasing the differential. Some devices on the market solve this by adding a fan (requiring electricity). Another possibility is to use water for cooling. &lt;br /&gt;

&lt;div&gt;[[File:StirlingEngineOnMount.jpg|250px|thumb|right|&#039;&#039;&#039;Alpha prototype under construction&#039;&#039;&#039;. See [http://openstirlingengine.blogspot.com/ Open Stirling Engine blog] for the current status of the first prototype of the 4 cylinder alpha configuration engine.

&lt;br /&gt;
=Overview=&lt;br /&gt;
A [[Stirling Engine]] can operate quietly from any heat source to generate mechanical power (work). It operates by cyclic compression and expansion of air or other gas, the working fluid, at different temperature levels such that there is a net conversion of heat energy to mechanical work. It can be coupled directly to a hydraulic transmission, although only a handful of projects have explored this possibility over the decades. &lt;br /&gt;
&lt;br /&gt;
Heat sources include [[Solar Concentration]] power  as well as [[biomass]]. &lt;br /&gt;
&lt;br /&gt;
See also [[Sterling Engine/Ericsson Engine]]&lt;br /&gt;
&lt;br /&gt;
==Applications and Product Ecology==&lt;br /&gt;
* In future versions of the [[GVCS]], such a concept may be used for the [[Power Cube]] &lt;br /&gt;
* can be coupled to water pumps for irrigation   &lt;br /&gt;
* biomass: heat can be derived from combustion or from [[pyrolysis]], where [[biochar]] would be a useful, carbon-negative byproduct. With biomass-powered Stirling engine, one single engine could handle all sorts of different biomass, whether solid, liquid or gaseous. There is no need for tedious clean-up of fuel. &lt;br /&gt;

&lt;br /&gt;
=Assessment=&lt;br /&gt;
From MJ - Regarding the Stirling engine, that is not one of our [[GVCS 50]] technologies, so we are less interested in that - unless we are convinced that a practical model that can put out at least 100 watts of usable power from a small solar concentrator or biomass heat source. I understand that Stirling engines are more challenging to make work than modern steam engines based on the track record that Stirling engines never gained wide use, while steam engines were the backbone of the industrial revolution. For this reason - we are pursuing a modern version of a historically disruptive technology - the modern steam engine. We are currently building the [[Hadden Engine]]. However, I am quite open to collaboration on the stirling if someone can convince me, based on technical merit, that we can have a reliable product within a 3 year time frame that meets OSE specifications of lifetime design and low cost. This is possible but more challenging than the modern steam engine route. However, [[Dean Kamen]]&#039;s third world Stirling engine product appears to show that the feasibility is there - the question being - is it sufficiently simple, cost effective, and robust to meet [[OSE Specifications]]. - Nov 13, 2012&lt;br /&gt;

See [http://openstirlingengine.blogspot.com/ Open Stirling Engine blog] for the current status of the first prototype of the 4 cylinder alpha configuration engine. This is a simplified version of the design as modeled in Google SketchUp]] &lt;br /&gt;

&lt;br /&gt;
=Overview=&lt;br /&gt;
A [[Stirling Engine]] can operate quietly from any heat source to generate mechanical power (work). It operates by cyclic compression and expansion of air or other gas, the working fluid, at different temperature levels such that there is a net conversion of heat energy to mechanical work. It can be coupled directly to a hydraulic transmission, although only a handful of projects have explored this possibility over the decades. &lt;br /&gt;
&lt;br /&gt;
Heat sources include [[Solar Concentration]] power  as well as [[biomass]]. &lt;br /&gt;
&lt;br /&gt;
See also [[Sterling Engine/Ericsson Engine]]&lt;br /&gt;
&lt;br /&gt;
==Applications and Product Ecology==&lt;br /&gt;
* In future versions of the [[GVCS]], such a concept may be used for the [[Power Cube]] &lt;br /&gt;
* can be coupled to water pumps for irrigation   &lt;br /&gt;
* biomass: heat can be derived from combustion or from [[pyrolysis]], where [[biochar]] would be a useful, carbon-negative byproduct. With biomass-powered Stirling engine, one single engine could handle all sorts of different biomass, whether solid, liquid or gaseous. There is no need for tedious clean-up of fuel. &lt;br /&gt;

&lt;br /&gt;
=Assessment=&lt;br /&gt;
From MJ - Regarding the Stirling engine, that is not one of our [[GVCS 50]] technologies, so we are less interested in that - unless we are convinced that a practical model that can put out at least 100 watts of usable power from a small solar concentrator or biomass heat source. I understand that Stirling engines are more challenging to make work than modern steam engines based on the track record that Stirling engines never gained wide use, while steam engines were the backbone of the industrial revolution. For this reason - we are pursuing a modern version of a historically disruptive technology - the modern steam engine. We are currently building the [[Hadden Engine]]. However, I am quite open to collaboration on the stirling if someone can convince me, based on technical merit, that we can have a reliable product within a 3 year time frame that meets OSE specifications of lifetime design and low cost. This is possible but more challenging than the modern steam engine route. However, [[Dean Kamen]]&#039;s third world Stirling engine product appears to show that the feasibility is there - the question being - is it sufficiently simple, cost effective, and robust to meet [[OSE Specifications]]. - Nov 13, 2012&lt;br /&gt;

&lt;br /&gt;
=Study of Industry Standards=&lt;br /&gt;
&lt;br /&gt;
*See also [[Industry Standard Pellet Burners]] - not necessarily gasifier burners&lt;br /&gt;
*Wayne Keith and list of open gasifiers - [http://www.driveonwood.com/library/free-gasifier-plans/]&lt;br /&gt;
&lt;br /&gt;
== Design Criteria ==&lt;br /&gt;
The gasifier should be designed in such a way that it can satisfy a specific set of use cases. These use cases should consider the availability of three products produced by the gasification process, namely Heat, Ash or char and combustible gases.&lt;br /&gt;
&lt;br /&gt;
Use of excess heat:&lt;br /&gt;
*heat air in a shelter&lt;br /&gt;
*dry fuel for the gasifier&lt;br /&gt;
&lt;br /&gt;
Use of ash and char:&lt;br /&gt;
*soil amendments&lt;br /&gt;
*lye production for:(ash may have to much carbon for quality lye production)&lt;br /&gt;
**soap products&lt;br /&gt;
**lye stabilized earth&lt;br /&gt;
**Feedstock for [[Open Source Lye Production Apparatus]]&lt;br /&gt;
&lt;br /&gt;
Use of combustible gases:&lt;br /&gt;
*Steam Generator&lt;br /&gt;
*Power Cube&lt;br /&gt;
*Truck&lt;br /&gt;
*Car&lt;br /&gt;
*Kiln &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
=== Portability ===&lt;br /&gt;
Unit should be available in both portable and fixed arrangements. portable configurations should enable vehicle (trailer?) mounting. &lt;br /&gt;
reactor module design could be impacted.  Will refractory cement handle the jostling around? &lt;br /&gt;
&lt;br /&gt;
=== Modularity ===&lt;br /&gt;
A good design should allow for flexibility in design variability without loosing compatibility between the various components. This need may be more pronounced during development. &lt;br /&gt;
modules include:&lt;br /&gt;
*fuel bin&lt;br /&gt;
**different Sizes&lt;br /&gt;
**Autoloading? (designed with this in mind not necessarily needed)&lt;br /&gt;
*reactor core and ash collection&lt;br /&gt;
**variability in configuration depending on feedstock&lt;br /&gt;
**hearth material may vary depending on portability&lt;br /&gt;
*cyclone filter&lt;br /&gt;
*gas cooler&lt;br /&gt;
*filters&lt;br /&gt;
*manifold for gas delivery (optional)&lt;br /&gt;
*flare&lt;br /&gt;
&lt;br /&gt;
===Capability===&lt;br /&gt;
How large a generator should this unit supply? A gasifier operating above designed capacity can cause damage to the reaction chamber and grate and operating significantly below capacity can lead to high tar production, the most difficult problem facing engines ran on producer gas.&lt;br /&gt;
&lt;br /&gt;
===Other Considerations===&lt;br /&gt;
ability to interface with:&lt;br /&gt;
*screw type ash cleanout&lt;br /&gt;
*auto fuel loader&lt;br /&gt;

&lt;div&gt;Walking through the 50 Technologies and Their Economic Impact&lt;br /&gt;
&lt;br /&gt;
Disclaimer - Graph of completion&lt;br /&gt;
Here we discuss all the tools, but please remember that in Part 1 of the 4 Part Series, many of the machines are still on the drawing board.&lt;br /&gt;
&lt;br /&gt;
=Agriculture=&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
If you eat, you use a Tractor. Maybe not you directly, but the farmer that grew your food. And food is a $8T industry. The GVCS field agriculture machinery that support this $8T industry &amp;lt;ref&amp;gt;https://www.plunkettresearch.com/statistics/Industry-Statistics-Global-Food-Industry-Statistics-and-Market-Size-Overview/&amp;lt;/ref&amp;gt; are:&lt;br /&gt;
&lt;br /&gt;
Fig 1. The Tractor, Microtractor, Microcombine, Universal Seeder, Spader, Hay Cutter, Hay Rake, Baler, and Dairy Milker, and a Bakery Oven are critical tools of the $8T food industry.&lt;br /&gt;
&lt;br /&gt;
==Tractor, MicroTractor, Bulldozer and Power Cubes==&lt;br /&gt;
&lt;br /&gt;
The tractor is a cornerstone of a farm, construction, or other materials production industries. A tractor has the traction to pull things, and to do utility work with variou implements that can be added to a tractor and use the tractor’s mechanical power through a Power Take-off (PTO). As such, the tractor can be a swiss army knife of heavy duty work. For the smaller individual or home scale, we have the MicroTractor in the set, which is a small, walk-behind or ride-on tractor at the 16-32 hp size that can perform many gardening and utility functions and can fit in a smaller areas where a large tractor would be impractical. If we go up in scale - use a stronger frame and at least 64 hp, and add a bulldozer blade to the tractor - then we have a bulldozer.&lt;br /&gt;
&lt;br /&gt;
The tractor is a machine on the scale of 50-320 hp in the GVCS ecosystem, and unlike traditional tractors, we focus on modular power. We currently use small 16 hp engine units at $17/hp (ref), which is the lowest cost way to obtain engine power, while making maintenance very easy. Like in nature where a tree is made of many branches, our tractor is made of many small engine units. This way, the same design pattern can be used in the 16 hp tractor as in the 320 hp tractor. The price for using larger diesel engines is 2-4 times larger.  &amp;lt;ref&amp;gt;http://opensourceecology.org/wiki/Diesel_Engine_Cost &amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
By using the modularity concept, we create our typical construction set approach for heavy machines. For example, if a large tractor frame is fitted with a bulldozer blade - then we don’t require a separate bulldozer in addition to a tractor. This saves a lot of resources - making technology significantly lower cost to maintain. Exploring the limits of modularity, we found that it is much less expensive to scale our machines usig modular and overbuilt parts that make sense both for small and large machines. For example, we can use 4 of our identical track units, each rated for up to 80 hp - Our track unit, for example, allows for a $30k version &amp;lt;ref&amp;gt; http://opensourceecology.org/wiki/Modular_Track_Unit_v18.01&amp;lt;/ref&amp;gt; that matches the traction of a Cat D7 - a sizeable cost savings comprd to a base price of ½ a million. &amp;lt;ref&amp;gt;https://www.caranddriver.com/reviews/caterpillar-d7e-feature-test &amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Fig. Pattern Language for a Tractor - up to automated control.&lt;br /&gt;
&lt;br /&gt;
The key is making it easy and quick to interchange parts - from small parts to large implements. This is a great challenge for advanced industrial design.&lt;br /&gt;
&lt;br /&gt;
Fig. Industrial smaller parallel and trained configuration. OSE machines can be designed like this, but higher flexibility of the OSE platform can allow for an improved configuration.&lt;br /&gt;
&lt;br /&gt;
Fig. The flexibility of a modular OSE tractor. The modular OSE tractor can be built from the same components, but apply to 16 hp or 320 hp machines while using the same over-engineered components such as the ½” thick steel tracks &amp;lt;ref&amp;gt;Current design is rated for  rated for 40 hp per track or 80 hp with double drive, . (ref - do calculations) and 3600 lbs or 7200 of pull each. Thus, a four-tracked machine can have 29,000 lb of pulling force with direct drive using our current 15k in-lb motors.&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
==Spader, Seeder, Bulldozer==&lt;br /&gt;
&lt;br /&gt;
Your food today is grown largely by tractor-driven  tilling and seeding, unless you’re a breatharian. Tillage in the OSE system chooses the spader as a more progressive technology compared to the age-old plow. &lt;br /&gt;
&lt;br /&gt;
Fig. (Image of 1800 steam tractor with 50 bottom plow) &lt;br /&gt;
&lt;br /&gt;
The spader works essentially like  a bunch of shovels moving rapidly - which till soil without crating a hardpan typical of the more common plow. Manufacturers claim that spading uses 40% less fuel than plowing - because a spader can combine tilling, harrowing, and planting in one operation. &amp;lt;ref&amp;gt;https://www.farmax.info/PDF/Magazine-Farmax-EN.pdf &amp;lt;/ref&amp;gt; A plow, which drags through the soil, requires a lot of wheel-to-ground  traction, whereas a spader requires very little - thus avoiding soil compaction. It takes a spader under 9 minutes and 2 gallons of fuel per acre of field - such that feeding Dunbar Village &amp;lt;ref&amp;gt;A village of 200 -  based on Dunbar’s number https://en.wikipedia.org/wiki/Dunbar%27s_number &amp;lt;/ref&amp;gt; would take 6 hours to plant for a whole year of crop &amp;lt;ref&amp;gt;Assuming field crops planted with a seeder, not slips like sweet potatoes. http://opensourceecology.org/wiki/Acres_Needed_to_Feed_Dunbar_Village &amp;lt;/ref&amp;gt;Thus, one day to plant, two days to harvest - and the village has food for the year. &lt;br /&gt;
&lt;br /&gt;
The tractor and universal seeder is an example of how we approach multiple purpose machines. The tractor is a large-size swiss army knife for doing many different tasks. The Universal seeder is designed to plant all types of seed, from alfalfa to wheat, to tubers, and to live plants like sweet potato slips. Modifying the device rapidly is key to this flexibility.&lt;br /&gt;
&lt;br /&gt;
Fig. Swiss army knife tractor concept&lt;br /&gt;
&lt;br /&gt;
The point of using powerful machines wisely is that in the OSE perspective of lifetime growth -  life could become easy so we can focus on evolving as humans. Our experiment involves building a college campus where peole live this. When they graduate, they know how to organize a village to spend 2 hours per day working on survival, and then the rest of their life they pursue their highest ideals.&lt;br /&gt;
&lt;br /&gt;
The experimental village thus requires one farmer who is employed 3 days of the year, assuming the equipment does not break down, and generates 30 acres * $20k/acre of sweet potato, and $5k/acre for 10 acres of wheat if that is turned into bread  - or $650k worth of food for the community with direct marketing. That is $27k/hour if baking is automated - a decent pay, but not like the $25k/minute rate of Warren Buffett &amp;lt;ref&amp;gt;http://www.businessinsider.com/what-warren-buffett-makes-per-hour-2013-12  &amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Of course these are unreasonable figures, but they do represent the idea. The only way that customer acquisition and marketing costs do not ruin such ideals is in the case of direct marketing - where the on-site farmer-scientist provides for a captive audience of the Dunbar village. If each person eats about $2600 per year &amp;lt;ref&amp;gt;https://www.google.com/search?q=average+cost+of+food+per+year&amp;amp;oq=average+cost+of+food+per+year&amp;amp;aqs=chrome..69i57j0l5.7243j1j7&amp;amp;client=ubuntu&amp;amp;sourceid=chrome&amp;amp;ie=UTF-8&amp;lt;/ref&amp;gt;, feeding 150 people would involve revenues of $390k - but that would be a full time job. We will look more carefully at the business model for resident farmer agriculture in the Enterprise chapter.&lt;br /&gt;
&lt;br /&gt;
Now it would take more time to do a diversified operation, but this is shown just as a baseline to see what’s possible in terms of the effort.  Several Ph.D.’s can be granted to develop a diversified, 40 acre subscription farm, using open source equipment and a captive market, or Local Food Nodes as part of a distribution platform.  &amp;lt;ref&amp;gt;https://localfoodnodes.org/&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The OSE project will develop such a food enterprise both for its campuses and for the outside community - once all the farming machines are done, the aquaponic greenhouse production is optimized, and derivative food processing tools are developed.&lt;br /&gt;
&lt;br /&gt;
The open source tractor can be built at a cost of $125/hp at a scale of 80 hp, compared to $370-$1000 for other brands. It is useful to understand the basic cost breakdown based on off-the shelf parts:&lt;br /&gt;
&lt;br /&gt;
Fig. Cost breakdown of a tractor by Frame, engine, hydraulics, control, automation, and balance of system - $125/hp. (p590MJ)&lt;br /&gt;
&lt;br /&gt;
The cost advantage is less visible at the 32 hp MicroTrac, at $160 per hp - though but a comparable mahine like the tracked Toro Ding costs around  $1000/hp (ref).&lt;br /&gt;
&lt;br /&gt;
Fig. Microtrac with tooth bar bucket can till your garden, and provide valuable utility work. It is an indidspensible utility machine for any prosumer.&lt;br /&gt;
&lt;br /&gt;
==Hay Cutter, Rake, Baler==&lt;br /&gt;
&lt;br /&gt;
If farm animals are involved, then you need these. Or if you want to move large quantities of materials, then a bale is a useful form: from a bale of hay, brush, cotton, cardboard, or plastic - bales allow large scale moving of materials. Bales of aluminum cans are likewise useful for melting down in your induction furnace. If you are making fuel pellets from biomass, plastic pellets for making 3D printer filament - you will need a baler to make 1 ton bales.&lt;br /&gt;
&lt;br /&gt;
==Dairy Milker== &lt;br /&gt;
For animal husbandry, hay baling stores hay for the winter. Unless you are talking about the fish in your home aquaponic system. Dairy products themselves are $116B &amp;lt;ref&amp;gt;https://www.ibisworld.com/industry-trends/market-research-reports/manufacturing/food/dairy-product-production.html &amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
of the global economy - hence the relevance of the dairy milker. &lt;br /&gt;
&lt;br /&gt;
Table: values of the overall food, dairy, cattle, vegetable markets worldwide.&lt;br /&gt;
Combining the dairy milker with computer vision and automation, we envision a solar robotic milker - our MicroTrac with a milking stall - that drives up to a cow to milk her, and then brings the milk back for storage and processing. This allows field milking without human labor for small diversified robofarms that combine the best of regenerative agriculture with modern tehnology to relocalize farming.&lt;br /&gt;
&lt;br /&gt;
Fig. Robotic milker&lt;br /&gt;
==MicroTrac== &lt;br /&gt;
&lt;br /&gt;
A very interesting use arises with a small, solar, robot tractor - the MicroTrac driven by a solar panel. By adding a $10 Raspberry Pi Zero Controller &amp;lt;ref&amp;gt;https://www.adafruit.com/product/3400?gclid=EAIaIQobChMI2rz0mcnd2gIVCzlpCh3MpQgIEAQYAiABEgKi7_D_BwE&amp;lt;/ref&amp;gt; and a $100 solar panel you can be your robotic tractor - for agriculture and other. You can now mow your lawn automatically, and even pelletize it for fuel for a pellet stove. This is possible because today - advanced microelectronics such as the Raspberry Pi is 100 times faster that the first supercomputer, which cost $9M &amp;lt;ref&amp;gt;https://www.theregister.co.uk/2008/01/05/tob_cray1/ &amp;lt;/ref&amp;gt; in 1975.&lt;br /&gt;
&lt;br /&gt;
Fig. A solar-driven MicroTrac concept with solar panel and $50 arduino controller can provide autonomous agriculture &lt;br /&gt;
&lt;br /&gt;
==Bulldozer==&lt;br /&gt;
&lt;br /&gt;
Now add a bulldozer blade to a beefed up, tracked tractor - and you have one of the most powerful devices for regeneration - or destruction - depending on how you use the machine. Bulldozers are powerful earth moving machines - to build roads, grade house foundations, and in agriculture - to build regenerative earthworks for water and erosion. The biggest example is the 12,000 square miles that have been regreened in China - the Loess Plateau. &amp;lt;ref&amp;gt;John Liu reported on this - http://www.aquinta.org/news/2016/10/6/greening-the-desert  &amp;lt;/ref&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Fig.&#039;&#039;&#039; Loess Plateau reforestation&lt;br /&gt;
&lt;br /&gt;
So, if you ever drove on a road - you used a bulldozer. Maybe not you, but whoever graded the road base. &lt;br /&gt;
&lt;br /&gt;
==Microcombine==&lt;br /&gt;
&lt;br /&gt;
The Microombine is used to harvest grains and seeds of any type. This is the core of human harvests world wide. For the OSE case, we have a much more flexible and modular machine in mind. Based on our module-based aproach, we can use the same drive platform as the tractor&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Fig&#039;&#039;&#039;. Showing the base drive platform that can be used &lt;br /&gt;

==Bakery Oven==&lt;br /&gt;
&lt;br /&gt;
Humble bread is a $419B global market https://www.ibisworld.com/industry-trends/global-industry-reports/manufacturing/bakery-goods-manufacturing.html . It is the 12th most popular food in the world. https://www.farmflavor.com/at-home/what-is-the-most-popular-food-in-the-world/  And 49% of Americans eat bread  https://www.smithsonianmag.com/smart-news/each-day-50-percent-america-eats-sandwich-180952972/ . &lt;br /&gt;
&lt;br /&gt;
Now bulldozers, tractors, and combines are all good - but the next step for gobal agriculture is the transition to  perennial polyculture  https://www.youtube.com/watch?v=KpJR2yfLUU0  , with only a small fraction of tillage ramaining.&lt;br /&gt;
&lt;br /&gt;
=Construction - 13 Tools=&lt;br /&gt;
If you want to build a charter city or a smaller campus, you will need construction equipment - and a trencher to put in gigabit internet fiber between the locations.&lt;br /&gt;
&lt;br /&gt;
The tools in the construction part outside of the tractors include the backhoe, trencher, cement mixer, sawmill, CEB press, well-drilling rig, soil pulverizer, hammermill. The universal rotor is a tool used in other sectors of the GVCS - and the SeedHouse is a living machine. &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Fig. 13 tools of the construction part of the Global Village Construction Set.&lt;br /&gt;
&lt;br /&gt;
==Backhoe, Trencher, Cement Mixer==&lt;br /&gt;
&lt;br /&gt;
The backhoe or excavator can be used to dig aquaponic ponds, foundation trenches. It can be used to remove stumps, do trenching, and with a grapple it can be used to lift logs or to hoist heavy objects. Backhoes are relatively simple devices - a set of pivot joints that use hydraulic cylinders for their motion - producing thousands of pounds of digging force at the touch of control levers. There are both side-to-side moving backhoes, but a 360 degree rotating backhoe is much more flexible. The small side to side version can be used on a front quick attach of a tractor.&lt;br /&gt;
&lt;br /&gt;
Fig. OSE backhoe from 2010 https://www.google.com/search?q=ose+backhoe&amp;amp;client=ubuntu&amp;amp;hs=ToH&amp;amp;source=lnms&amp;amp;tbm=isch&amp;amp;sa=X&amp;amp;ved=0ahUKEwjLzZKelOLYAhULbawKHQo-DVwQ_AUICigB&amp;amp;biw=1351&amp;amp;bih=731#imgrc=t8j52U9--mn6BM:  mounted on he original lifetrac, a small one used for water line trenching in 2012 http://opensourceecology.org/wiki/File:Bhp1.jpg , and a larger one from 2013 https://www.youtube.com/playlist?list=PL6Jpysxw3Ty-oH4bggp32PR_rPWr8bKC1 . Next iteration is the 360 degree backhoe with remote control drive to facilitate hydraulic line routing.&lt;br /&gt;
&lt;br /&gt;
The trencher in the original GVCS icon is a wheel trencher. We built 2 prototypes, and the next iteration will be a chain-based trencher based on our favorable experience with oversized chain drive on the bulldozer tracks.&lt;br /&gt;
&lt;br /&gt;
Fig. OSE Trencher http://opensourceecology.org/wiki/Trencher - 2011 and 2013 builds.&lt;br /&gt;
The cement mixer is indispensable. Cement has been used in ancient Rome and in mesoamerican temples. Scotland&#039;s County Cork had 23,000 lime kilns at one time - had one kiln per 80 acres. Wood or coal was used as fuel. http://www.lowtechmagazine.com/2013/09/lime-kilns.html  http://www.chapelgatehome.uk/our-blog   Portland cement took over lime cement in the last 100 years, but lime concrete is favorable in foundations becaue it doesn’t crack as easily as Portland. Using modern appropriate technology, lime cement production in solar microfactories is a viable enterprise at the 1 ton per day scale using an open source microkiln the size of a refrigerator. Limestone goes in one end, and lime comes out the other. With such small appliances costing around $1k, cement production can be distributed - while making cement production carbon neutral, annihilating  the current 5% CO2 emission share of the the concrete industry.https://en.wikipedia.org/wiki/Environmental_impact_of_concrete  This is possible in about 50% of America, where the bedrock is made of limestone. That’s a $10B industry in the USA alone.https://en.wikipedia.org/wiki/Cement_industry_in_the_United_States &lt;br /&gt;
&lt;br /&gt;
The cement fryer - a rotary lime kiln - is much like the cement mixer: a Universal Rotor with a heating element. A rotating pipe heated by PV, and an Arduino microcontroller to measure temperatures and guide the process to efficient completion. While not part of the 50 GVCS technologies, it’s a ready derivative:&lt;br /&gt;
&lt;br /&gt;
Fig. PV of the Open Source Materials Production Facility, a solar Power Cube, a Universal Rotor, metal pipe and an Arduino microcontroller constitute the lime cement maker.&lt;br /&gt;
&lt;br /&gt;
If we want to go to the essence of construction, take the backhoe excavator, chase it with a bulldozer with ripper shanks, and then rock under a site could be extracted to build a pond. This rock, if limestone, is feedstock for your lime kiln. In some places, rock outcroppings make access to limestone easy.&lt;br /&gt;
&lt;br /&gt;
==CEB Press , Soil Pulverizer, and Sawmill==&lt;br /&gt;
&lt;br /&gt;
The Compressed Earth Brick press and sawmill are critical tools for construction in that they produce materials. The CEB Press allows one operator to load raw dirt right from the building site to produce about 5000 bricks in a day - enough for a small house. &lt;br /&gt;
&lt;br /&gt;
Fig. The CEB Press is the first machine that we have prototyped, and it is ready for widespread replication around the world.&lt;br /&gt;
&lt;br /&gt;
We have used the soil pulverizer to prepare soil for pressing CEB blocks. The soil pulverizer was used to both pulverize the soil, and its bucket was used to press bricks for CEB construction.&lt;br /&gt;
&lt;br /&gt;
Fig. Soil pulverizer - Aidan on the tractor + loading the brick press by Yoonseo&lt;br /&gt;
&lt;br /&gt;
Our next step on the CEB press is a full soil conditioner which pulverizes soil, adds cement at a measured quantity of 5%, and then loads the mixture into the CEB press - to allow for production of high quality, stabilized block.&lt;br /&gt;
&lt;br /&gt;
Fig. The soil conditioner accepts raw soil from a tractor loader, mixes a measured amount of cement, and loads the prepared mixture into the CEB press for effective production of stabilized block at 12 cents ( 10 cent cement cost for a 20 lb block, and 2 cents gasoline cost). per block in materials. This means that we can build a 1’ thick CEB wall section for $50 in materials.&lt;br /&gt;
&lt;br /&gt;
The sawmill is a machine that can produce dimensional lumber - a staple of construction. Our sawmill is a variety known as a swing-blade sawmill, which has a single blade that can rotate 90 degrees and make a dimensional piece of lumber by going forward and back on a piece of wood.  We chose the dimensional sawmill for its simplicity over a bandsaw mill, as blade sharpening is much easier - and maintenance is the larger cost of any equipment if that equipment is designed for a lifetime.&lt;br /&gt;
&lt;br /&gt;
The sawmill is a good example of how we can use GVCS product ecologies to reduce complexity and reduce the cost of equipment. We design not just individual machines, but machine ecosystems that feed off one another. We can obtain drastic cost reduction by borrowing existing modules from the GVCS. For our case, it makes sense to design the sawmill as a Bobcat standard quick attach implement. We borrow the tractor as a  quick attach point, so that we do not need a bed upon which the sawmill head would otherwise ride. We borrow 32 hp from the tractor Power Cubes. We also  borrow the hydraulic motor which we attach with hydraulic quick-connect hoses. Thus, we have essentially stripped down the entire sawmill to the long carriage with the cutting head - saving $2k https://www.ebay.com/itm/30hp-Kohler-Engine-1-1-8-D-Command-15Amp-Exmark-CH750-0026/132423001888?epid=26011371639&amp;amp;hash=item1ed506a720:g:4YUAAOSwH2VaS3-h  on the engine, $2k https://sleequipment.com/dovetail-utility-trailer-7x20-with-3500lb-axles.html?fee=8&amp;amp;fep=524834&amp;amp;gclid=EAIaIQobChMIws349azn2AIVBqxpCh1rMwbpEAQYASABEgIeHPD_BwE  on a trailer. The greatest advantage would be the setup time - if designed as a quick attach implement, the sawmill can be taken to a log, rested right by the log, and ready for action - as compared to systems where the carriage base must be set up or the log moved into cutting position. If the sawmill can straddle right over a log or be raised with the loader arms, there is no limit ot the size of log that the mill can handle. &lt;br /&gt;
&lt;br /&gt;
Fig. The simplicity of the OSE swing-blade sawmill involves a long linear track mounted as an implement for the tractor. To provide 3 axes of motion - the loader mounting includes height adjustment (z motion), and a lightweight cantilevered head provides side-to-side motion. The cost of about $1500 is significantly lower than the $15k http://www.dltimbertech.com/dl-180-swing-blade-sawmill-10-x-20.html   minimum for a comparable 32 hp sawmill. (ref)&lt;br /&gt;
&lt;br /&gt;
And the sawdust that we generate can be used as animal bedding, insulation, or it can be pelletized to make fuel pellets.&lt;br /&gt;
&lt;br /&gt;
==Universal Rotor==&lt;br /&gt;
&lt;br /&gt;
The Universal Rotor is a fundamental building block for just about any moving machine. It is a combination of rotary motion and a useful tool-head. As a design pattern consisting of a shaft, bearings, and a motor -  a wide array of working tools can be attached to it - so that the Universal Rotor can constitute a drill, a wind turbine,  a wheel, a hammermill, cement mixer, sawmill - etc  - essentially any machine at any size - from small cordless electric drills to a larger 50kW rotor of a wind turbine. &lt;br /&gt;
The Pelletizer , Chipper/Hammermill, Dimensional Sawmill, Rototiler/Soil Pulverizer, Cement Mixer, Well-Drilling Rig, 50 kW Wind Turbine, Microcombine Thresher, and Bioplastic Extruder are direct applications of the universal rotor, and combined with precision machining structures, the Universal Rotor also include the heavy duty CNC Multimhttps://www.opensourceecology.org/portfolio/pelletizer/achine with lathe, drill press, slow cutoff saw, surface grinder, and other machines of fabrication.&lt;br /&gt;
If we can build a Universal Rotor, a Power Cube, and weld together  a supporting structure - then we have - broadly speaking - built 23 of the 50 machines of the GVCS. For example, if we consider the electric motor - it is a a shaft, 2 bearings, a structure, and the ‘tool head’ could be considered the electrical windings that make the shaft spin. Or, if we consider the metal lathe - a part of the Multimachine - then it is clear that the lathe consists of a heavy shaft, 2 heavy bearings, and the tool-head is a chuck for holding work-pieces.&lt;br /&gt;
&lt;br /&gt;
==12. Well-Drilling Rig and Chipper/Hammermill==&lt;br /&gt;
The well-drilling rig is a machine used to dig deep water wells. It consists of a universal rotor which uses 3” (https://www.aquascience.net/grundfos-10sq05-160-230v-10gpm-1-2hp-230v-2-wire-96160140-3-stainless-steel-submersible-well-pump?gclid=EAIaIQobChMIlt-S3PDn2AIVC6tpCh369g34EAQYASABEgJr__D_BwE. 10’ of this pipe store 4 or 6.5 gallons of water. ) or 4” drill pipe to drill down to a depth of 100m or more using hydraulic rotary drilling. In this method, a stream of water is sent down the pipe during the drilling operation to send up tailings and soften the area of the drill point. A heavy duty hydraulic motor spins the drill rod - and new sections of drill rod are attached one after another. When the operation is done, the drill pipe is left underground and a submersible pump is inserted to pump water from the well.&lt;br /&gt;
Fig. A hydraulic deep well pump drilling system explained. The water swivel is the key part here. Otherwise 3” pipe that can be used as  drill pipe and casign is $12/foot. https://www.discountsteel.com/items/Galvanized_Steel_Pipe.cfm?item_id=172&amp;amp;size_no=11#skus  &lt;br /&gt;
The chipper/hammermill is another application of a universal heavy rotor with swinging or fixed blades. This machine shreds or pulverizes materials, and can be as small or large as needed.&lt;br /&gt;
Fig. Hammermill variations with various blades to chip wood or crush rock. A modified version of a heavy rotor can be a grinder. The scale can be from the largest - shredding cars - to the smallest - with small electric motors - if you have hydraulic drive and electric drive.&lt;br /&gt;
&lt;br /&gt;
==The House - Seed Eco-Home and Aquaponic Greenhouse==&lt;br /&gt;
&lt;br /&gt;
The Seed Eco-Home is a living machine - and becase it is the single largest cost of living today, we dediced to include that in the GVCS. (Initially, the house was not in the GVCS - but it was added as the Microhouse.) The Seed Eco-Home is the culmination of all the construction machines put to use. Homes are  also about  $3T (https://en.wikipedia.org/wiki/Construction#Industry_characteristics - residential construction is about ⅓ of all construction) market worldwide - which if open-sourced, could provide 30 million regenerative housing jobs for open source home building entrepreneurs Earning $100k each per year. This is 30 million potential collaborators - through we need only about 1000 at this time.&lt;br /&gt;
&lt;br /&gt;
The OSE/OBI https://www.openbuildinginstitute.org/  Seed Eco-Home is a an affordable, expandable eco-home that can be built for ⅓ the cost of a typical home, while including ecological features. Rather than building a large house, we propose starting with a seed home, and then growing it as the need arises. &lt;br /&gt;
&lt;br /&gt;
We are pushing ecological limits in our autonomous house design. The house is  off-grid with PV, provides its own cooking fuel from a biodigester, includes roof-top rainwater collection, and grows its own food with an aquaponic greenhouse. Mowed lawn or biomass is used to provide heating biomass pellets for a hydronic stove that is fueled by pellets. The eventual product vision is a house that  produces fuel for cars as compressed biogas or compressed hydrogen - by splitting water. Thus, we are correcting the oil and gas industry with 100% renewable energy, using simple, proven technologies. We are not relying on advancements in battery technology as a prerequisite to sustainable transportation, and by not requiring scarce lithium for batteries, we are aiming for an abundant and environmentally friendly energy future. http://www.kitco.com/ind/Albrecht/2014-12-16-How-Green-is-Lithium.html  We favor rooftop PV plus electrolysis as the preferred route for transportation fuels, where every house becomes a gas station. Using medium pressure electrolyzers that can produce hydrogen up to 33 atmospheres without needing a compressor - we can readily store hydrogen in large propane tanks or higher pressure steel pipe. &lt;br /&gt;
&lt;br /&gt;
Fig. Seed Eco-Home&lt;br /&gt;
&lt;br /&gt;
Fig. Aquaponic greenhouse glamour shot.&lt;br /&gt;
&lt;br /&gt;
The aquaponic greenhouse is designed to provide a year-round supply of fresh eggs, vegetables, fish, and mushrooms. The goal is to include automated planting with a small Farmbot (https://farm.bot/ . By Shuttleworth Fellow friend Rory Aaronson.), where the resulting deep pots are planted in the  towers. With a 1000 plant growing capacity in the main towers, the greenhouse can provide a robust salad daily, where we plant and harvest 15 plants per day from a small 800 sf greenhouse. A mushroom yield of 1lb is obtained per week from a tower that takes only 1 square foot. We also intend to use automated 3D printed aerial drones for planting seeds directly into towers - a great example of useful product ecology. Local food addresses the issue of food miles, where food travels an average of 1500 miles in the USA before ending up on someone’s plate. https://cuesa.org/learn/how-far-does-your-food-travel-get-your-plate  This is one of the numerous inefficiencies that will be addressed by a more efficient, open source economy. This brings us to transportation.&lt;br /&gt;
&lt;br /&gt;
=Transportation. =&lt;br /&gt;
&lt;br /&gt;
The microcar, truck, electric motor, and hydraulic motor are the 4 GVCS machines directly related to transportation. &lt;br /&gt;
&lt;br /&gt;
The worldwide production of cars is a total of 95M per year, 75% of which is done by the top 15 companies. https://en.wikipedia.org/wiki/Automotive_industry#World_motor_vehicle_production  This lends itself to massive distribution of power. The OSE paradigm proposes instead that there would be on the order of million distributed enterprises - essentially one per 10,000 people. Each facility would produce cars on the scale of dozens or hundreds in the community-supported manufacturing (CSM) scenario. Thus, car producers replace car dealership  - as the producer takes to dealing.  This would go well with a gas station at every home, splitting Seed Eo-Home rooftop water for fuel at a cost of 80 cent per gallon of gasoline equivalent. http://opensourceecology.org/wiki/Hydrogen_Production &lt;br /&gt;
&lt;br /&gt;
Fig. Seed Eco-Home to car fuel infrastructure consists of rooftop water collection, 10kW of PV panels, a storage tank for hydrogen, and compression to 200 bar. Piece of cake if you consider not doing this - wars for oil. This gives us about 100 miles of fuel worth per day in a 100mpg microcar.&lt;br /&gt;
&lt;br /&gt;
==OSE Microcar==&lt;br /&gt;
&lt;br /&gt;
The OSE Microar is a Hydrogen Hybrid Hydraulic (H3) vehicle. Hydrogen is chosen because an internal combustion (ICE) engine running on hydrogen is twice as efficient (40%) as a normal ICE (20%), and only 25% under the 50% efficiency of fuel cells. http://environment.yale.edu/gillingham/hydrogenICE.pdf A hydraulic drive train (71% efficiency) - has a higher efficiency than a continuously variable transmission (60%) for fuel cell electric vehicles - meaning that the humble hydrogen hydraulic car gets a higher mileage than a fuel cell car, at significantly lower cost. At a design weight of only 850 lb, less than ¼ of a typical car, the OSE microcar focuses on moving the passenger, not a large chunk of metal accessory to the core purpose. Lighter cars have a good safety record. Before the S.U.V. boom, the country (USA) had the world&#039;s lowest highway death rate.http://www.nytimes.com/2004/05/05/business/averag e-us-car-is-tipping-scales-at-4000-pounds.html  Additionally, gas mileage for the OSE Microcar is specified for 100mpg. While not as testicular as a Tesla, the OSE specification requires higher self-esteem on the part of the driver to accept acceleration from 0-60 of 12 seconds, as opposed to under 3 seconds for a Tesla Model S.https://en.wikipedia.org/wiki/List_of_fastest_production_cars_by_acceleration&lt;br /&gt;
&lt;br /&gt;
Fig. The OSE Microcar concept.&lt;br /&gt;
&lt;br /&gt;
Are smaller cars safer? This is controversial. https://www.ptua.org.au/myths/smallcar/  Physics says that energy of motion is proportional to v squared, and data shows that 56% of car deaths are single-car collisions. So unless you are going to hit another oncoming car or an immovable object like a large tree, your tiny car of under 1000 lb  has 36x less energy to dissipate than a Chevy Suburban of 6000 lb. And, the lightest car - the Smart Carfortwo at 1800 lb http://driving.ca/hyundai/accent/auto-news/news/these-are-the-ten-lightest-cars-you-can-buy-in-2015  and it certainly does get eaten up in a frontal 2 car collision with a larger car. And crashes took more than 37k lives in the US http://www.iihs.org/iihs/topics/t/general-statistics/fatalityfacts/state-by-state-overview#Crash-types  , with 20-50x more if injuries are counted. http://asirt.org/initiatives/informing-road-users/road-safety-facts/road-crash-statistics (are injuries better or worse in large cars?)&lt;br /&gt;
&lt;br /&gt;
But this is all before self-driving cars enter the scene - which have been tested for 0 driverless car crashes over 1.8 million miles by Google - with 13 fender benders caused by other cars. http://bigthink.com/ideafeed/googles-self-driving-car-is-ridiculously-safe  In other words, the case is there for super-small, super-efficient cars that are robotically controlled. &lt;br /&gt;
&lt;br /&gt;
What we have in mind follows the standard of the 200 mpg fuel efficiency of the VW  L1 first prototype car, at 640 lb weight, 8 hp, top speed of 75 mph, with tandem seating for 2. https://en.wikipedia.org/wiki/Volkswagen_1-litre_car. The efficiency dropped to 170 mpg in a hybrid version - http://gas2.org/2009/09/14/volkswagens-diesel-hybrid-1l-concept-gets-170-mpg-available-by-2013/  If OSE achieves the same with 16 hp instead of 8 hp, and using hydraulics while not needing to go to a hybrid drive-train that apparently reduced its initial mileage performance - then we will have a major victory for open source-  Hydraulic accumulators may be used for peak power.  Plus, we’d like to achieve this with hydrogen as fuel in later versions.&lt;br /&gt;
&lt;br /&gt;
More specifically - our model is an H3E car - including a hybrid electric component.  The hydraulic component is a peak power electric-hydraulic micro-Power Cube of about 40 lb additional weight - powered by the onboard starter battery for its cranking amps.  This additional 30 seconds of a starter battery would double the power of the 16 hp engine - such that burst of energy for passing and sudden acceleration can be achieved easily.&lt;br /&gt;
&lt;br /&gt;
==B The Solar Car==&lt;br /&gt;
&lt;br /&gt;
The Solar Challenge is a fascinating event that shows PV-covered cars traveling 62 mph average across Australia. Granted that the driving is in expensive prototypes ad a sunny country - only in daytime - this still bodes well for the feasibility of solar transportation. The typical cars used are small - surface area of a Toyota Prius - and the OSE version would be twice as large 24x8 feet for 3kW of installed PV + 44 lb Lithium ion batteries + 2.5 kW small engine. http://opensourceecology.org/wiki/Solar_Car This allows for a total of 7kW of continuous power for one hour, or 4 kW total power continuous - at 750 lbs of weight. This just may work - if we 3D print a form frame for carbon fiber layup. 3D printing here may be the enabling technology.&lt;br /&gt;
&lt;br /&gt;
==Truck==&lt;br /&gt;
&lt;br /&gt;
The truck is a medium-size, hydraulic, 80 hp driven vehicle comparable to the Mercedes Unimog. https://en.wikipedia.org/wiki/Unimog  With a design top speed of 62 mph,  a weight of 6550 lb, and a hydraulic power take-off, the OSEmog could function as an agricultural tractor as well. The OSEmog is designed to accept a loader or various implements on the front or back. Using basic hydraulic circuits, the machine would have high and low gear, and speed cotrol via simple flow control valves.&lt;br /&gt;
&lt;br /&gt;
Fig. The OSEmog is a multipurpose truck for carryng loads or operating various implements. With off-the shelf parts, it is designed to be field serviceable, and the working hydraulic fluid can be grown - canola oil with additives.&lt;br /&gt;
&lt;br /&gt;
==Hydraulic and Electric Motors==&lt;br /&gt;
&lt;br /&gt;
Both the car and truck have a choice of using hydraulic or electric drive. The advantages of hydraulics are low-cost, high torque, and simplicity of resulting drive design. Hydraulic motors cost only $10/hp, half that of electric motors - but a typical 40 hp hydraulic motor weighs about 50 lb http://opensourceecology.org/wiki/45.6_Cu_In_Hydraulic_Motor as opposed to about 350 lb https://inverterdrive.com/group/Motors-AC/TECA2-200L-4-Pole-B3-High-Efficiency-AC-Motor-200/ .  Typically electric motors are high speed and need to be geared down - whereas hydraulics can be used largely with direct drive. If high torque electric motors are used - these are more like $100/hp when the controller is included - making the drive system 10x as expensive for larger machines.  Electric motors are sensitive to moisture and dirt, while hydraulics are designed for dirty environments. &lt;br /&gt;
&lt;br /&gt;
We use electric motors and generators - in solar electric power cubes - or in wind turbines. But the flexibility, power, and simplicity of hydraulics is a better choice for practical applications - especially when powered by hydrogen and transmitted by canola oil as the hydraulic fluid.&lt;br /&gt;
&lt;br /&gt;
The electric motor can also be 3D printed, making it fit with the OSE product ecology. &lt;br /&gt;
&lt;br /&gt;
Fig. A proprietary, 3D printed, 600W, 80% efficient electric motor. The equivalent is worthwhile to open-source.&lt;br /&gt;
&lt;br /&gt;
Electric motors can be both linear and rotary. In the linear form, they are known as solenoids - very useful devices that are used to make valves. For automation - we use hydraulic valves to control machines like the brick press - and solenoids are used wherever pneumatic or hydraulic controls are needed. This means any automated system - from the water control in aquaponics to the control of an industrial robot.&lt;br /&gt;
&lt;br /&gt;
The electric motor of interest ranges from a small 5W one to power a cordless drill - to the 50kW scale for use in the 50kW wind turbine.&lt;br /&gt;
&lt;br /&gt;
This brings us to the energy sector.&lt;br /&gt;
&lt;br /&gt;
=Energy Tools=&lt;br /&gt;
&lt;br /&gt;
The sun currently shines 10000 times more power to the earth than the entire civilization uses. The implications are profound: there is no such thing as an energy shortage. Energy scarcity is an imagined problem if we talk about actual availability of energy.&lt;br /&gt;
&lt;br /&gt;
We look at it as- it is a high priority to trap solar energy directly - by effective solar design of buildings (Homes and businesses spend about 50% of their energy on heating and cooling. )- and using photovoltaic energy (Solar Concentrator) to generate electricity locally, with wind (50kW Wind Turbine) wherever possible. For machines, the choice is to use hydrogen, charcoal, and compressed biogas. &lt;br /&gt;
&lt;br /&gt;
Hydrogen is by far the most efficient and clean when derived from water (as opposed to refining from oil and gas).  The process gives 0 pollution, and the product of hydrogen combustion is water. The OSE platform calls for provent internal combustion engines running on hydrogen as an immediately executable transition to a renewable energy future in transportation. Leading research institutes, such as the Rocky Mountain Institute (ref), promotes the hydrogen economy as the future, and hydrogen as a future energy source is not controversial if one assumes abundance of fuel feedstocks and distribution of energy production. Solar hydrogen can be produced anywhere, and wind hydrogen can be produced in most places around the world. We do not put such a high stake into batteries or supercapacitors when it comes to energy for cars, simply because chemical fuels are up to 140 times as energy dense. A typical energy density chart typically has chemical fuels off-the-charts good:&lt;br /&gt;
&lt;br /&gt;
Fig. Show specific energy density of storage media, with bats and caps, and chemical fuels, for perspective - https://en.wikipedia.org/wiki/Supercapacitor#/media/File:Supercapacitors-vs-batteries-chart.png. With supercapacitors having 100x less energy storage per weight than Lithium-Ion batteries, while costing 10x as much as ($2.85/kJ) as those batteries ($0.8/kJ), they are super-completely out of the question with today’s technology except for niche applications. Engines are .5kW/kg https://en.wikipedia.org/wiki/Power-to-weight_ratio#Engines  and Fuel (gas, diesel, methane) is 50MJ/kg and hydrogen is 140MJ/kg - or 50-140x more energy per weight than batteries. Given the environmental challenges of mining and recycling scarce metals, there is little case for battery-powered cars.&lt;br /&gt;
&lt;br /&gt;
That means that a non-battery car can lug around a higher percentage of payload (persons, cargo) rather than carrying around more car structure and batteries. &lt;br /&gt;
&lt;br /&gt;
For other purposes, biofuel pellets are desirable for heating fuel (after energy efficiency and solar thermal is maxed out) - such as by an aquaponic greenhouse with a black tubing heat exchanger.&lt;br /&gt;
&lt;br /&gt;
Biofuel pellets can be burned partly to release heat in winter - and if taken out of combustion after the volatile chemicals are burned off but before carbon burns to ash - then we have produced charcoal that can be used in a combustion engine. Thus, dual-fuel hydrogen/charcoal cars are in our view the transportation of the future. We are open to fuel cells entering the scene, and at $134/kW they are almost feasible.https://energy.gov/eere/fuelcells/fuel-cell-technologies-office-accomplishments-and-progress  They are too complex at this point for easy DIY production, so we may revisit this in 10 years if the technology becomes more accessible. Currently, fuel cells require exotic plastics and platinum, both of which are scarce resources. We are aiming for a sub $10k car which can be made with a standard internal combustion engine (ICE) running on hydrogen. Did you know that the first internal combustion automobile in the world ran on hydrogen in 1808? https://en.wikipedia.org/wiki/Fran%C3%A7ois_Isaac_de_Rivaz  Furthermore, ICEs are about 20% efficient - ICEs running on hydrogen are about 40% efficient. For comparison,  fuel cell vehicles are 50% efficient.http://environment.yale.edu/gillingham/hydrogenICE.pdf  Given that the efficiency gain of 25% of fuel cells over hydrogen ICEs comes at a 10x larger cost today, the case for pursuing hydrogen ICEs is much higher than the case for fuel cells. much cheaper H2ICE are seen by many experts as the means to provide a transition between emitting and non emitting transport and stationary system. https://pureenergycentre.com/hydrogen-engine/ &lt;br /&gt;
&lt;br /&gt;
Fig. The possible cost of a fuel cell car today for a 200kW sedan is $26k - and an overall minimum of about $75k. The open source hydrogen microcar is aimed at an under $10k cost and more than 100 mpg using widely available technology. (comparison of components and price, using ref 3 above)&lt;br /&gt;
&lt;br /&gt;
The answer already under our nose that is perhaps the most optimistic case for the energy revolution is solar power - at 0.015 cent per kilowatt-hour - demonstrated in 2016 by the Seed Eco-Home. http://opensourceecology.org/wiki/Hydrogen_Production  This is 4x cheaper than gas turbine electric generation  https://qz.com/135032/fuelcell-energy-fuel-cell-profit/  , and it allows for an equivalent 80 cent per gallon electricity cost for producing hydrogen.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
==The Power Cube==&lt;br /&gt;
&lt;br /&gt;
Our current Power Cube is a universal power unit that can power any of the large GVCS  machines, from cars to lathes to the brick press. The Power Cube is gasoline powered and has a 16 hp engine. We already ran this on charcoal gas - and as such - the same power cube can readily be used in dual-fuel operation - gasoline on the one hand, and charcoal on the other. Once we add the gas production infrastructure - the power cube can run on the hydrogen and biogas production from the House.  Because the pelletizer is part of the GVCS - we can make charcoal pellets from biomass pellets as a byproduct of space heating.  The concept of pellets is important - in that pellets are a flowable fuel. Meaning - that just like gasoline or tradition fuels - it can be stored in a tank and delivered as fuel as if it were a liquid - by using a small auger. This makes pellets a convenient fuel source, which unlike wood - can be used automatically in small machines.&lt;br /&gt;
&lt;br /&gt;
Moreover, the Power Cube can be run on solar energy, allowing for autonomous tractors and solar cars to enter. Solar power cubes are a good idea for shop power - where PV on the workshop roof feeds electric power cubes for hydraulic shop power. Power cubes can also be made very small - on the 1 kilowatt scale. They can also be stacked readily for higher power, so if we want a 160 hp bulldozer, we can do that based on our existing Power Cube.&lt;br /&gt;
&lt;br /&gt;
The Power Cube involves developing open source engines so that they enter the realm of lifetime design public technology. A universal version of an open source engine means that such an engine could be maintained and produced in a distributed fashion, bringing it closer to appropriate technology with a lifecycle that includes more reusability of parts.&lt;br /&gt;
&lt;br /&gt;
Fig. The Power cube and its different fuel sources - from gasoline, to charcoal, to compressed biogas, hydrogen, and electric.&lt;br /&gt;
&lt;br /&gt;
The large torque of hydraulics makes them very flexible for driving a wide range of machines. A small power cube, such as a 300W version running on a single solar panel, can be used to drive a 2000 lb MicroTrac as a practical, autonomous tractor.  The idea is that the machine would move very slowly - all day - on solar power. This is afforded by that fact that hydraulics have high torque at any speed - making this a perfect application of solar energy to autonomous, robotic tractor drive via a small microcontroller such as a $10 Pi Zero with Wireless.https://www.adafruit.com/product/3400   Thus, we can pull chicken tractors or pig tractors with a solar robotic tractor for a diversified agriculture operation.&lt;br /&gt;
&lt;br /&gt;
Fig. Infographic. Mega power cubes for 160 hp for a bulldozer, and a micro power cube for a solar grinder/pelletizer or chicken tractor.&lt;br /&gt;
&lt;br /&gt;
Autonomous animal tractors are another possible application of Power Cubes…&lt;br /&gt;
&lt;br /&gt;
Fig. The economic breakdown of an autonomous chicken tractor. PV panel + micro power cube at $500, plus the tracked drive for another $500 with open source hydraulic motors. The hydraulic motors (SME) are produced on the open source lathe (SME).&lt;br /&gt;
&lt;br /&gt;
==The Gasifier ==&lt;br /&gt;
&lt;br /&gt;
The OSE  gasifier is a device that converts charcoal into gas for fueling engines. Note that this gasifier uses charcoal that is produced as a byproduct of space heating. The gasifier is a metal container filled with charcoal, which upon being lit via in a small burn zone with an air inlet - burns and produces gas. This gas can be used as fuel in a regular internal combustion engine. The power of this lies in that with minimal modifications, a standard engine can be fueled by charcoal - which is derived from wood or other biomass.  This means that wherever plants grow - they provide a distributed and practical fuel source byond oil wars. https://www.cnn.com/2013/03/19/opinion/iraq-war-oil-juhasz/index.html  To produce charcoal, biomass is first pelletized. Burning pellets for space heat - and removing them from the burn before they turn to ash - produces charcoal pellets.&lt;br /&gt;
&lt;br /&gt;
Fig. Infographic. Space heating produces charcoal in the OSE ecosystem.  The Gasifier vaporizes charcoal, which is then burned in a standard engine. This process can be used to fuel cars - no engine modification required.&lt;br /&gt;
&lt;br /&gt;
The first reaction may be that if we turned plants into vehicle fuel - then we would destroy all of nature. That is not true, because there is plenty of biomass reserve that can be used to fuel the entire American car fleet, which uses about 60% http://needtoknow.nas.edu/energy/energy-use/transportation/  of all the energy in the transportation sector. Did you know that the largest single crop in the United States is lawn? There are 40 million acres of turf grass. http://scienceline.org/2011/07/lawns-vs-crops-in-the-continental-u-s/  What if we turned lawns into fuel crop, while increasing esthetics and reducing herbicides? Yields of grass are 4 dry tons per acre https://en.wikipedia.org/wiki/Biomass  - and if charcoal is produced at 25% efficiency - that is one ton of charcoal per acre - or 40 million tons of charcoal can be harvested from lawns alone, with no effect on food production, while increasing the ecological diversity of lawns. The average american uses 500 gallons per year of fuel.  https://www.treehugger.com/culture/pop-quiz-how-much-more-gas-do-americans-use.html  Lawns could thus provide ¼ of the entire car fleet fuel in the USA! (Charcoal is ¾ the energy content of gasoline by weight. At about 3 kg/gallon - 500 gallons is 1500 kg- about 1.5 metric tons - so 33M people could be supplied by fuel from lawns. If 95% of households have cars - https://photos.state.gov/libraries/cambodia/30486/Publications/everyone_in_america_own_a_car.pdf - and household is 2.6 - there are about 120M drivers in the USA. Thus  - ¼ of US drivers can be fueled by lawns.) This is at the crappy USA 23 miles per gallon - so increasing fuel efficiency to 100 mpg https://www.motherearthnews.com/green-transportation/green-vehicles/build-your-own-car-zm0z13amzmar with super-efficient micro-cars could mean that the entire US car fleet is supplied by fuel from grass. Efficiency and ecology - as opposed to battery technology with questionable environmental side effects and its centralization based on scarce resources - make the OSE platform converge on biomass and hydrogen as the fuels of choice. The OSE platform reserves the role of batteries only as a small part of vehicular power, not the backbone of the auto industry. &lt;br /&gt;
&lt;br /&gt;
The biomass route needs no technical invention to realize - today - and is also a carbon-neutral route. From the OSE perspective - hydrogen is clean (it produces water as the byproduct) but not better on ecological grounds (it does not contribute to biological ecology) - but it is much better on efficiency grounds.&lt;br /&gt;
&lt;br /&gt;
When discussing biofuels, it is important to point to the food-fuel-fiber integrated agroecology route as the preferred OSE route to agriculture. As opposed to genetic engineering to produce super-crops, the OSE platform favors ecological integration over genetic manipulation - so that we avoid creating super-problems at the same time. The ecological route means that we learn more about dealing with integrated ecosystems, not trying point solutions (genetic engineering) as a cure. When dealing with powerful technologies like genetic engineering, we must pay attention to unintended consequences. The current economic paradigm of profit maximization is not compatible with care in the use of genetic engineering. We favor increasing productivity by stacking yields of multiple crops that work harmoniously in a polyculture setting - with tree crops as a significant component. For us, the breakthrough work of Badgersett Research Farm is seminal in providing this leadership. They are developing perennial crops (hazelnuts and chestnuts) that could serve as a viable replacement for soybeans and corn. (ref).  Hazelnuts and chestnuts provide the same nutrition as their annual counterparts - but are perennial - and therefore do not contribute to the average 4 ton per acre annual soil erosion in the United States. (ref). Let me repeat that - the avarage topsoil loss in the United States - per acre - is 4 tons. What that means is that agricultural soils today are so depleted that they could not grow crops if it were not for the heavy inputs of fertilizers. The biological activity of commercial farmland is severely depleted (ref), not sustaining the soil food web of microbes that bring fertility back to the soil. (ref). Our proposition for perennial polyculture - is not new (ref on seminal works, Tree Crops, Regrarians, etc) - and it can produce food, fuel, and other materials.&lt;br /&gt;
&lt;br /&gt;
To improve the world, all you need to do is plant trees. Desertification still claims an additional ______________ square miles every year, and it would be good to reverse that.&lt;br /&gt;
&lt;br /&gt;
It takes less than 60x the land area to produce solar hydrogen compared to the land area required to grow biofuel crops.  Between biofuel (easy) and hydrogen (hard), humanity’s fuel needs can be met. Let’s look at numbers: we already said 300 gallons of fuel equivalent per acre (enough to fuel one car for a year at a fuel economy of 40 MPG https://www.google.com/search?q=average+miles+per+year+usa&amp;amp;oq=average+miles+per+year+usa&amp;amp;aqs=chrome..69i57j0l2.7415j0j7&amp;amp;client=ubuntu&amp;amp;sourceid=chrome&amp;amp;ie=UTF-8 ) fuel consumption -  roughly one gallon per day. If we apply this to hydrogen - 50kWhr of electricity is required to produce 1 kg of hydrogen, roughly one gallon gas equivalent. This can be obtained from a 9 kW PV array - running 6 hours per day - 54kWhr. The space required for a 9 kW array is 60 square meters if the panels are 15% efficient. An acre is 4000 square meters - so producing solar hydrogen requires 66 times less land area than growing the equivalent grass. Our materials cost for 9 kW of solar panels is under $9k. So one can obtain 20 years of hydrogen fuel for a PV investement cost of $17k.&lt;br /&gt;
&lt;br /&gt;
Fig. Home hydrogen production. The OSE open source goal is $9k for PV panels, $2k for storage, $2k for pump, $2k for plumbing, and $2k for the electrolyzer. That is $17k for a lifetime supply of hydrogen. Compare to gasoline - $1250/year on average. Payback time for  home fuel station is 14 years in the USA and 7 years in Europe. We intend to make hydrogen production a standard feature of the Seed Eco-Home.&lt;br /&gt;
&lt;br /&gt;
Add a paragraph about renewable energy plantations - perennial polycultures for fuel, food, fiber. &lt;br /&gt;
&lt;br /&gt;
Fig. Basic economic model for renewable energy plantations involves $x/acre in coppiced fuel, $1000/acre in nuts, and $2k/acre in sustainable chickens that fertilize the crop via autonomous chicken tractors.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
==Heat Exchanger==&lt;br /&gt;
&lt;br /&gt;
The heat exchanger is a device that takes heat from one medium and puts it into another. For example, in the Seed Eco-Home - we have a hydronic stove with heat exchanger which is used to heat water for heating the house.&lt;br /&gt;
&lt;br /&gt;
Fig. Hydronic stove with heat exchanger. A heat exchanger heats water, and if that water is boiled, it can be used to run a steam engine or turbine. Small steam engines have been used for shop power 100 years ago, and they can be used even more effectively today. You can get a working kit for $275 on Ebay.&lt;br /&gt;
&lt;br /&gt;
Simpler examples of the heat exchanger are the Hillbilly Heater. This device traps solar heat and puts it into water circulating through the black tubing. This energy is released through another coil in the aquaponic ponds, for example. A closed heat exchanger means that the water in the black tubing does not mix with the pond water. Or, this heat exchanger could be an open heat exchanger, where the water is heated and then used as hot water in a shower - so that a steady supply of new water is fed through the exchanger instead of just circulating - as in the pond heating case.&lt;br /&gt;
&lt;br /&gt;
Fig. The hillbilly heater can be used to heat ponds or to provide hot water for the house.&lt;br /&gt;
&lt;br /&gt;
==Modern Steam Engine==&lt;br /&gt;
&lt;br /&gt;
The modern steam engine is an engine that produces power from steam. The industrial economy was created by steam power. And steam turbines are the main way that power is generated today. &lt;br /&gt;
&lt;br /&gt;
A modern steam engine is a small engine that makes sense to build wherever space heating is involved. For example, a centrally heated building could be generating power at the same time as its being heated - if a heat engine with a generator is added to the system. Thus, we are piggy-backing on an existing power source, while using all the waste heat.&lt;br /&gt;
&lt;br /&gt;
Under 500 hp - or in any small scale installation - it is more effective to have a steam engine as the engine of choice. Above 500hp, it is more effective to use a steam turbine. Large power plant steam turbines reach 50% efficiency. https://en.wikipedia.org/wiki/Steam_turbine#Practical_turbine_efficiency &lt;br /&gt;
&lt;br /&gt;
A flame-fired or solar-powered heat exchanger can produce steam - for electricity generation. This makes sense for combined-heat-and-power systems. Most of today’s electricity is produced by water that is boiled in power plants to provide electricity via steam turbines. (ref) This can be done effectively on a scale of 500 or more horsepower - which is village scale, not home scale. For the smaller scale, a small steam engine can be used. For this reason, we have incorporated a modern steam engine into the GVCS - as a machine for producing electricity on top of a heat source. This could be done in our hydronic stove - where the water goes from the steam engine and then to house heating after some power has been extracted for electricity. It makes sense to convert the heat into high grade electricity - when the steam engine is connected to a generator.&lt;br /&gt;
&lt;br /&gt;
Fig. Hydronic stove with power generation.&lt;br /&gt;
&lt;br /&gt;
Did you know that the modern steam engine - a specific advanced version -  is more efficient than the internal combustion engine? The Cyclone engine is a high tech, high temperature steam engine made of stainless steel and exotic materials - with thermal efficiency over 30%. http://cyclonepower.com/ &lt;br /&gt;
&lt;br /&gt;
There is another steam engine that received a lot of attention on the internet but appears not to work well - the Green Steam Engine. We do not endorse the engine, as suggested by Tom Kimmel of Kimmel Steam Power  http://kimmelsteam.com/green-robertengine.html  - and you can read more in an old blog post. (http://opensourceecology.org/steam-meet-report/ . I have since contacted Mr. Greene for data on Feb 1, 2018, but I have not been presented with any data.)&lt;br /&gt;
&lt;br /&gt;
All together, the modern steam engine is valuable for household power, if the Power Cube is used for mobile power. What would be the cost of a steam engine add-on to a household infrastructure? Small models of ¼ hp are available for under $300 in parts, (http://ebay.to/2EwmHWt ) and these are scalable readily to larger sizes. The current seed eco-home stove has sufficient power to run this engine, so only an additional pump would be required to feed water to this system.&lt;br /&gt;
&lt;br /&gt;
Integration of such a system would work well if pelletized biomass were used as fuel - and subsequently - charcoal would be produced for use in cars as a byproduct of household power generation. An interesting milestone would be an automated biomass energy system from an autonomous tractor-pelletizer - up to the production of charcoal as car fuel using gasifiers - all from one’s former lawn converted to bioenergy crop.  In such case, nickel iron batteries may be desirable in so far as excess energy storage from daytime solar power.&lt;br /&gt;
&lt;br /&gt;
Fig. The energy product ecology of the Seed Eco-Home includes solar hydrogen, biogas for cooking, and production of car fuel from the lawn.&lt;br /&gt;
&lt;br /&gt;
==Solar Concentrator==&lt;br /&gt;
&lt;br /&gt;
The modern steam engine equation becomes much more exciting when solar concentration is used. Using 30% efficient, modern steam engines, proven linear solar concentrators, and a night-time storage system based on large, insulated propane tanks with hot water - it is possible to produce an off-grid energy system with $100/kWhr energy storage costs - 4x cheaper than lithium ion batteries. https://en.wikipedia.org/wiki/Lithium-ion_battery  A breakthrough company - Terrajoule - has already demonstrated this. Then the question becomes - if this has already been shown in the first prototype of Terrajoule, why isn’t everyone doing this when the technology is all proven? One cannot beat the simplicity of water and solar heat as the ultimate storage medium. &lt;br /&gt;
&lt;br /&gt;
What can water really do? When water is heated but not allowed to expand, it turns to what is known as saturated water. A saturated liquid is a liquid whose temperature and pressure are such that any decrease in pressure without change in temperature causes it to boil. In other words, if a tank was not holding the water at pressure - that water would turn into steam.&lt;br /&gt;
&lt;br /&gt;
Just how much energy can that water store at a medium pressure? A lot. Looking at the total heat content of water that would otherwise turn to steam, but is held under pressure at 18 atmospheres (250 PSI) in a tank instead http://opensourceecology.org/wiki/Saturated_Water  - we see that each kilogram of such saturated water holds about ¼ kWhr of energy. That means that a 10,000 gallon propane tank can store about 4MWhr of energy! We can extract that energy with a modern steam engine, where steam engines from the 1950s got to about 30% efficiency. https://en.wikipedia.org/wiki/Uniflow_steam_engine   After all the losses, we would have 300kWhrs of electricity when the modern steam engine runs a generator.&lt;br /&gt;
&lt;br /&gt;
We can scale that down to a residential system - just a 1000 gallon propane tank - and 30kWhrs of electricity produced.&lt;br /&gt;
&lt;br /&gt;
Fig. Cost and energy of a home-scale solar energy storage system using water and modern steam power. From energy content of 400kWhrs to 30kW hours of electricity is quite doable using proven technologies, at ¼ the cost of battery storage.&lt;br /&gt;
&lt;br /&gt;
==Nickel Iron Battery==&lt;br /&gt;
&lt;br /&gt;
Nickel-Iron Batteries are long-life batteries that have a track record of lasting 50 or more years. Unlike other batteries, these can be discharged fully without decreasing their lifetime. These are chosen for the Global Village Construction Set specifically for their long life - and becuase nickel and iron are not scarce resources. While heavier and 2x more expensive than lithium ion batteries, (Read an intereresting pro-con discussion - http://opensourceecology.org/wiki/Nickel_Iron_vs_Lithium_Ion_Battery_from_Tesla_Motors ) they make up by their long lifetime, and lend themselves to decentralized production. New developments are in progress, ( https://news.stanford.edu/news/2012/june/ultrafast-edison-battery-062612.html )  though OSE does not rely on new developments for feasibility given that OSE internalizes social and environmental aspects for true cost accounting. The cost is currently high because production volume is low - only 2 US manufacturers. Based on a nickel price of $6/lb and iron at 25 cents/lb, and a weight of 100 lb for 1kWhr - and a 20% content of nickel in nickel iron batteries https://www.solarpaneltalk.com/forum/off-grid-solar/batteries-energy-storage/ni/7052-how-much-nickel-is-really-in-a-ni ckel-iron-ni-fe-battery - the base materials cost of materials in Nickel Iron batteries appears to be $150/kWhr. That is similar to lead acid batteries and ½ of lithium ion costs - but if the lifetime of these batteries is really 50 years, then they are 5-10x cheaper than other batteries based on lifetime.&lt;br /&gt;
&lt;br /&gt;
According to recent research: https://link.springer.com/content/pdf/10.1007/s10800-015-0911-3.pdf &lt;br /&gt;
&lt;br /&gt;
There are many reasons favouring the use of NiFe cells as cost-effective solutions to store grid-scale amounts of energy, such as low cost of raw materials, environmental friendliness, electrical abuse tolerance, long life (in the order of thousands cycles of charge and discharge) and compatibility with photovoltaics (PVs). Due to the nature of the heavy metals involved in its construction this technology is suitable for stationary low gravimetric energy applications (30–50 Wh kg-1 ). As a consequence, there are good reasons to foresee a large scale utilization of this technology. Due to their outstanding safety properties (zero flammability, fail safe, no over/ under charge), low cost and long lifetime, we anticipate that they will receive widespread public acceptance for customer-connected energy storage.&lt;br /&gt;
&lt;br /&gt;
It is our hope that the nickel iron battery would be only a small fraction of electrical power storage needs in the future - such as replacing 5-year lifetime starter batteries in vehicles. For night time electricity, it would be useful for warmer regions to use solar concentrator saturated water storage - as one possibility - or solar hydrogen as another.&lt;br /&gt;
&lt;br /&gt;
In colder areas, biomass is typically available as an abundant energy crop - where PV may not be adequate if there are weeks without sun. The exact mix of solar concentrator electric, PV, wind, charcoal, biomass, biogas, and hydrogen is to be determined at Factor e Farm as we measure the value of all these systems side by side. The main requirement for OSE is true service to humanity, environmental regeneration, and freedom from resource conflicts.&lt;br /&gt;
&lt;br /&gt;
==50 kW Wind Turbine==&lt;br /&gt;
&lt;br /&gt;
A wind turbine converts a renewable form of energy - wind - into electricity. It provides a good backup to PV electricity, as wind typically blows when the sun is not out.&lt;br /&gt;
&lt;br /&gt;
We propose a vertical axis wind turbine for the initial OSE version based on integration with hydraulics and the Universal Rotor.  A simple system can consist of a pole mounted 40 hp hydraulic motor ($400), serving as a pump - which transfers fluid power to an on-the-ground hydraulic motor ($300) + 24 kW generator ($1000). The power generator related costs are ~ $2000 here, and the rest is the tower and structure. With $6k spent on the materials for this wind turbine, this would be $250/installed kW in materials costs - with installation being 15% on top of this http://www.esru.strath.ac.uk/EandE/Web_sites/14-15/XL_Monopiles/cost.html  - a very attractive package in a sweet spot of cost for readily-available components. This is compared to $1590/kW standard costs of large scale wind installations. https://www.awea.org/falling-wind-energy-costs &lt;br /&gt;
&lt;br /&gt;
The OSE design features a generator that is mounted on the ground, with only the hydraulic motor on top of the tower. This facilitates maintenance considerably. The savings is due in part to the great simplification of the nacelle - in the OSE case, the vertical axis design doesn’t have a yaw mechanism - it’s just a hydraulic motor that accepts wind from any direction. These turbines are not as efficient in terms of wind capture as they are lower to the ground - but the low capital + maintenance costs make up for the lower efficiency. Because they can be packed more tightly in the same area, however - VAWT wind farms can actually produce 10x the energy of a propeller-type wind farm. https://en.wikipedia.org/wiki/Vertical_axis_wind_turbine#Advantages  They also self-regulate their speed, so they do not need a braking meachanism for overwind conditions.&lt;br /&gt;
&lt;br /&gt;
Fig. OSE VAWT concept. Simplification of design include ground-mounted generator, yawless rotor, screw pile foundation https://en.wikipedia.org/wiki/Screw_piles#Modern_Use_and_Benefits  , and braking via the hydraulic motor as the overspeed protection. The wind turbine module is designed for 24 kW, and it includes the Electric Motor/generator, Universal Rotor, Hydraulic Motor, Power Cube, and Universal Power Supply for managing power.&lt;br /&gt;
&lt;br /&gt;
8. Universal Power Supply&lt;br /&gt;
The Universal Power Supply (UPS) is the last of the energy machines. It is a universal device for powering large electronic machines - induction furnaces, welders, plasma cutters, laser cutters - and for controlling power delivery and transmission to homes or electric cars. It is also used for charging. The UPS has feedback such that it would know when batteries are full, or for optimizing the power transfer into a load of metal that is melted with the induction furnace. &lt;br /&gt;
&lt;br /&gt;
The Universal Power Supply in general  converts AC and DC into voltages and currents of any amplitude and frequency. The UPS is scalable from a few watts to 20kW based on the same design of modules.  The Universal Power Supply can also be used to condition power from the wind turbine or PV system and pump it into the grid. It can also be used as an inverter to convert DC to AC, or it can be used to control the speed of an electric car. It can also be used to step power up to high voltage for power transmission over longer distances, such as up to the 69,000 volts for rural power lines. &lt;br /&gt;
&lt;br /&gt;
As with the mechanical machines, the Universal Power Supply is based on modular design, such that we can arrive at a Construction Set. Just like power units, wheels, shafts, hydraulic motors, control valves, and frames can create any mechanical industrial machine, so can a small number of modules provide just about any electrical power function in the Universal Power Supply. These modules are mainly: a microcontroller, a current measurement device, a transistor, wires, laminated cores, ferrite beads,  diodes, optocouplers, resistors, capacitors, and inductors - plus a few mechanical components such as plugs, cases, cooling systems. With advanced transistors that now cost $1 per kW of power handling, large power electronic devices can be built on the cheap if open source knowhow is available.&lt;br /&gt;
&lt;br /&gt;
Wires and metal cores themselves produce a wide range of devices: inductors, transformers, relays, solenoids, switches for large currents, electric motors, spark generators, electromagnets, and other devices. &lt;br /&gt;
&lt;br /&gt;
Lasers, charge controllers, inverters, welders, induction furnaces, plasma cutters, oxyhydrogen generator power supply, and motor controllers are all functions that can be generated with the Universal Power Supply. These are all based upon currents and voltages at different frequencies and amplitudes that perform radically different functions. This has to do with the nature of electricity - jus like a few atom types (100 or so) make up millions of different substances that are all around us - so can electricity be manipulated to perform a wide array of functions. Any of the above devices consist of a microcontroller and a power transistor - along with some resistors, capacitors, and inductors. The microcontroller could be an Ardduino or a Rasperry Pi - which now cost as little as $5 for these small computers running with a 700MHz cpu. This CPU - via software - can produce a voltage of any amplitude and frequency using transistors. In other words - a ‘brain’ - the CPU - can massage electrons so they maifest at any voltage or frequency - by using transistors - or devices where a small signal from a CPU controls a large voltage. Essentially - a transistor is a switch - which is activated by a small signal.&lt;br /&gt;
&lt;br /&gt;
For example - taking DC voltage - one can make it pulsed and appear as an oscillating sine wave. This is an inverter for household power - which can for example take electricity from PV cells and convert that into household current. Or - this same inverter can be pulsed much faster to create a 30kHz voltage used in an induction furnace. And regulation can happen - such as an induction furnace delivering power most effectively to the molten charge - when the same microcontroller can measure the voltage, and change the frequency of the applied voltage to pump power more effectively into the melt. &lt;br /&gt;
&lt;br /&gt;
This is all possible because superfast microcontrollers, and high power handling transistors - can all be purchased now for a few dollars.&lt;br /&gt;
&lt;br /&gt;
Energy Summary&lt;br /&gt;
&lt;br /&gt;
Combining biomass, charcoal, biogas, wind power, the solar concentrator,  steam electricity, hydrogen, PV - and the electronic controls of the Universal Power Supply -  makes for a resilient power infrastructure without necessitating resource conflicts.&lt;br /&gt;
&lt;br /&gt;
=Open Source Microfactory=&lt;br /&gt;
&lt;br /&gt;
The Open Source Microfactory (OSM) is the crown jewel of the Global Village Construction. It is the part that allows for GVCS self-replication - in that the Open Source Microfactory allows for the production of all the  GVCS tools - including the Microfactory itself..&lt;br /&gt;
&lt;br /&gt;
The Open Source Microfactory is broken into 2 main parts: precision CNC tools, and metal production tools. The CNC tools - which stands for Computer Numerical Control - are automated machines that can be programmed to build things - from small parts, to engines, and everything in between. The metal production tools allow for the production of virgin steels from scrap. The steel that can be produced with the GVCS metal tools thus allows for the creation of advanced civilization - wherever there is access to scrap steel. Scrap steel is abundant, and so it iron ore from which steel is made. Iron is the 4th most abundant element in the earth’s crust - after oxygen, silicon, and aluminum. https://en.wikipedia.org/wiki/Abundance_of_elements_in_Earth%27s_crust &lt;br /&gt;
&lt;br /&gt;
What if there is no scrap steel available? We can go to aluminum - which is even more abundant in terms of the crust’s composition. Aluminum is found in common clay. Clay is aluminosilicate, from which aluminum can be extracted. Because Aluminum is so abundant - the GVCS goes so far as the extraction of aluminum from clay. This is intended to break through any notions of scarcity in today’s civilization.  Clay is abundant, and it’s an essential part of the GVCS: compressed earth blocks, soil for growing food, clay for 3D printed pots and cookware - in addition to the production of aluminum metal.  &lt;br /&gt;
&lt;br /&gt;
Fortunately - silicon is even more abundant. We get solar cells for producing electricity from silicon - a core technology for the GVCS such as in the Seed Eco-Home. In less than the time it takes to read this paragraph, the sun will have provided as much energy to Earth as used by all of human civilisation in one day. Thus silicon solar cells are important. And silicon is used to make semiconductors - so silicon creates the computer age.&lt;br /&gt;
&lt;br /&gt;
With the Open Source Microfactory - we thus aim to show that literally, modern civilization may be created -  from dirt and twigs. This can happen on any parcel of land - as solar cells can easily produce about 500kW of energy - from an acre. So a facility such as the OSE headquarters can produce all the technology required to produce an advanced civilization. For example, 500kW of solar energy - or 3MWhrs per 6 hours of daylight - can produce 200 kg of aluminum per day. Aluminum requires 15 kWhr per kilogram to smelt. (http://wordpress.mrreid.org/2011/07/15/electricity-consumption-in-the-production-of-aluminium/ . This one says ,05 GJ/kg - http://wordpress.mrreid.org/2011/07/15/electricity-consumption-in-the-production-of-aluminium/ )Aluminum is energy intensive - but its production may one day be improved for more environmentally-sound production - as can any other process by internalizing environmental costs.  https://www.sciencedirect.com/science/article/pii/S0360544207001065#! &lt;br /&gt;
&lt;br /&gt;
This shows how energy intensive aluminum production is - but its 3x better weight to strength ratio compared to steel makes it a desirable product. With the proposes 200kW solar microfactory - we can produce 80 kg of aluminum per day. That’s not a lot - but acceptable as a proof of concept for an appliance-size machine.&lt;br /&gt;
&lt;br /&gt;
Aluminium is the most abundant metallic element in the Earth’s crust (about 8%) and the&lt;br /&gt;
second most widely used metal next to steel. The aluminum production process involves taking ordinary clays such as abundant kaolin clay - and leaching out alumina with hydrochloric acid to produce Al203, which is subsequently turned to Aluminum via electrolysis at a cost of 15 kWhr per kg of aluminum produced. For reference in terms of energy requirements - this is like converting one gallon of gasoline to one kg of aluminum. That’s a lot of energy. But the main point here is that this can be done anywhere where there is soil - clay for making aluminum is an abundant feedstock.&lt;br /&gt;
&lt;br /&gt;
If we talk about the carbon dioxide emissions - whether from aluminum or steel production - the way we propose to make it sustainable is to make the CO2 recyclable. If the carbon involved in the reactions for producing metals - or for that matter any other product - comes from charcoal derived from biomass - then the industrial process is regenerative as the plants that were used to produce the charcoal took the carbon out of the atmosphere in the first place. Thus, a sustainable industry is possible  when civilization evolves to using charcoal  instead of fossil fuels. &lt;br /&gt;
&lt;br /&gt;
However, it should be stated that CO2 in the long run may be more advantageous for ecology - even from fossil fuels - if that CO2 yields more plant growth. While many people see CO2 per say as a global warming problem - it is also possible that the CO2 will make the earth more green. Nobody knows what will happen at this point - we can only speculate as to the long term effects of increasing CO2 in the atmosphere. &lt;br /&gt;
&lt;br /&gt;
The open source microfactory is intended to produce an entire technosphere from local resources, pushing the limits of what can be done:&lt;br /&gt;
&lt;br /&gt;
Fig. Open Source Microfactory cyclic material flows can be based on local resources. Metals, bioplastics, ceramics, PV cells, concrete, carbon, hydrogen, glass, rubber, fuels, food, construction materials, and many other chemicals can be produced from local abundance.&lt;br /&gt;
&lt;br /&gt;
If it is indeed that PV cells can be made from local sand, and aluminum from clay - and everything else as noted - then we have truly stepped into a world of post-scarcity. At the point where material production is guaranteed, it may be possible for people to evolve full time - without being held back by mere survival. That is the essence of society that OSE intends to create - one in which material needs are not in the way of human evolution.&lt;br /&gt;
&lt;br /&gt;
For any other processes of industry - the Open Source Microfactory can provide. If you can make buildings, glass, metal, and plastics + other materials - you can build anything. Advanced processes such as chemical plants or semiconductor fabs - are nothing but buildings, metal vessels, motors, vacuum pumps, and a few other basics - and from there spews out any product - in a nutshell. This does not even involve the nanotech of molecular manipulation - where it is deemed that in the future we will be able to synthesize substances by moving atoms directly - without regard for chemical reactivity as we know it today. Yet we do not invoke the Technological Singularity as a prerequisite for meeting all human needs.&lt;br /&gt;
&lt;br /&gt;
Let’s move to the specific tools in the Open Source Microfactory:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
And &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Fig. Tools of the Open Source Microfactory. They include everything needed to produce precision metal parts starting from scrap metals, glass, bioplastics, and even semiconductors for solar cells. &lt;br /&gt;
&lt;br /&gt;
==Universal Axis==&lt;br /&gt;
&lt;br /&gt;
Six of the Open Source Microfactory tools are based on the Universal Axis. The Universal Axis is a modular, and scalable CNC axis which can be used to create cartesian CNC machines. The core of the axis design is belt drive and linear motion rods where carriages are pulled on the rods. The system is scalable to any size and number of axes, including rotary axes. The system uses a combination of 3D printed parts, metal plates, and belt-driven shafts. Applications include 3D printers, CNC torch tables, heavy duty CNC machines, and many other production machines.&lt;br /&gt;
&lt;br /&gt;
We intend to use the 5/16”, 1”, and 2” versions for 3D printers, CNC torch tables, and heavy duty CNC machines - which are among the key machines that can be built with the system - though a variant of any size and shape can be designed.&lt;br /&gt;
&lt;br /&gt;
Fig. The universal axis comes in 5/16”, 1”, and 2” variations, and is based on belt drive, though a screw and nut system can also be used as a drive. Various tool heads can be attached. Non-contact tool heads are attached magnetically, such as the laser cutter and 3D printer. Rotary attachments can even be used for 3D scanning or indexing.&lt;br /&gt;
&lt;br /&gt;
For heavy duty applications, the plastic plates may be reinforced with steel plates - making a steel-plastic composite that has the required strength - while being easy to produce because the complex geometry is 3D printed. The metal plates themselves can be CNC cut using the CNC torch table. This allows for the lowest cost route - the 2” bushings capable of 8000 lb force on these axes currently cost only $9.41 at McMaster Carr.&lt;br /&gt;
&lt;br /&gt;
Fig. Metal-plastic Universal Axis System.&lt;br /&gt;
&lt;br /&gt;
The power of the universal axis lies in its flexibility. The same design of the drive system can be used to make an unlimited range of fabrication machines, putting the manufacturing process completely in the hands of anyone - without high barriers to entry. This is aimed at the Open Source Microfactory in every town, where our goal is to distribute at least 10,000 of these open source microfactories around the world, each generating at least $100,000 of net revenue per year. Once production returns to communities, we expect that taxes will go down as communities once again become responsible for their own prosperity.&lt;br /&gt;
&lt;br /&gt;
==The 3D Printer, Bioplastic Extruder, 3D Scanner==&lt;br /&gt;
&lt;br /&gt;
The 3D printer is a machine with diverse applications. Essentially, the technosphere is made from plastics, ceramics, and metals. 3D printers can print with all of these, and are as such ubiquitously applicable to manufacturing of all sorts. Currently, it is easy to print with all kind of plastic, including rubber for printing tires and polycarbonate for printing glazing. It is likewise easy to print ceramics - by printing clay and then baking it. Here we can produce ceramic cookware or clay parts such as insulators or building bricks. If the clay contains a large fraction of glass or metal - then upon kilning - 3D printed glass and metal objects can be printed as well. Metal printing can also happen via a MIG or TIG welder as the working toolhead - where large metal structures can be printed additively like this. If we go a step up to lasers - we can do selective laser sintering of any kind of powder - from plastic, to ceramic, to metal. Extremely strong, precise metal parts can be created this way - such that for example the rocket engine for Elon Musks’s SpaceX rockets has been 3D printed.&lt;br /&gt;
&lt;br /&gt;
Fig. Different applications of 3D printing: plastic, rubber, glass, metal, ceramic, and housing.&lt;br /&gt;
&lt;br /&gt;
Carbon fiber or metal fibers can also be embedded in plastic 3D prints to make the parts as strong as aluminum. 3D printing can also print ceramic molds which can then be used for casting directly into these molds - using either molten metal from an induction furnace or a MIG weld right into the metal form.&lt;br /&gt;
&lt;br /&gt;
Fig. Apparatus for automated metal casting using 3D printing of molds + induction heating of melt to fill the molds.&lt;br /&gt;
&lt;br /&gt;
Currently - open source printing includes  plastic + rubber 3D printing, welder 3D printing, clay printing for ceramics, clay-metal 3D printing for metals, selective laser sintering of plastics, and 3D priting of concrete or clay buildings. With a little bit of work,  the full printing with metal or glass using selective laser sintering can be developed by using off-the-shelf technologies. An 80W laser tube like in the Laser Cutter + shielding gas allows for selective laser sintering of off-shelf metal powders. http://opensourceecology.org/wiki/Metal_Selective_Layer_Sintering#Literature &lt;br /&gt;
&lt;br /&gt;
Fig. If metal powder is available (it is, such as iron at $1/lb) - then we can use a laser to fuse a powder bed to complex 3D objcts that cannot be produced in any other way.&lt;br /&gt;
&lt;br /&gt;
The world of 3D printing is in its infancy - and this is definitely worth refining to achieve full 3D printability in any material. Perfecting all of the above 3D printing can go far towards local production of just about anything.&lt;br /&gt;
&lt;br /&gt;
==Bioplastic Extruder==&lt;br /&gt;
&lt;br /&gt;
The Bioplastic Extruder is part of a system that enables the production of biodegradeable bioplastics from natural feedstocks such as cellulose or sugars. The system includes 3D printing filament production as well as direct extrusion of useful parts.  &lt;br /&gt;
&lt;br /&gt;
Four main aspects are involved in the Bioplastic Extruder System. First, a bioplastic reactor is used to make bioplastic from abundant biological feedstocks such as cellulose, sugar, or starch. Second - once the plastic is produced - or is available from the waste stream - it can be extruded with the Bioplastic Extruder to make 3D printing filament. Third, the 3D printing filament is then used directly in 3D printers to make useful objects. Fourth, other useful products can be made with the extruder: plastic lumber, which can be made from recycled plastic and sawdust. This could be a great way to recycle plastics into durable construction materials. Other useful profiles - such as tubing and glazing panels - can also be produced with the bioplastic extruder. Thus, the bioplastic extruder per se can be used for 2 main purposes: making 3D printing filament as an intermiediate feedstock for 3D printers - or extruding useful products directly.&lt;br /&gt;
&lt;br /&gt;
Fig. The bioplastic production system of the GVCS consists of bioplastic synthesis followed by extrusion to produce 3D printing filament, tubing, sheets, or plastic lumber. 3D printing filament can be used for 3D printing. Thermoplastic elastomers - or rubber - can also be printed.&lt;br /&gt;
&lt;br /&gt;
There are 3 types of bioplastics - those derived from: (1) petroleum and biodegradeable; (2) biomass and biodegradeable; and (3) biomass and non-biodegradeable. OSE is most interested in bio-based, biodegradeable bioplastics, as the feedstocks are most widely available and can be produced ecologically anywhere in the world. &lt;br /&gt;
&lt;br /&gt;
The OSE bioplastic system allows for local recycling such that the plastic never ends up in the landfill - but is either reused or recycled. By eliminating plastic waste and turning it into valuable products, wealth can be multiplied. Also, we can clean up the environment by reusing plastics - which can otherwise persist in the environment for 1000 years. Such recycling also reduces the need for petroleum - the typical feedstock of plastics.&lt;br /&gt;
&lt;br /&gt;
Bioplastics derived from biomass that are non-biodegradeable can be produced from petroleum substitutes. Petroleum can be replaced with charcoal. As such, any plastic typically derived from petroleum can also be produced from renewable, plant-derived charcoal. In the OSE system, plant matter is pelletized, then burned partially for space heating or process heat - with the byproduct being the important charcoal feedstock. If one is interested in replacing petroleum-derived chemicals - charcoal is first burned in a gasifier to produce CO and H2 - just as the gasifier fuels regular engines with CO and H2 - a combustible mixture. Instead of being burned in an engine as a renewable fuel, these molecules can combine under heat and pressure and an iron catalyst to produce long hydrocarbon chains and water. The long chains are alkanes - the typical long-chain molecules of -[CH2]- found in petroleum. This conversion process is known as Fischer-Tropsch synthesis, and is important from the abundance mindset - in that all products than now come from coal and petroleum can be made more ecologically - from plants. https://en.wikipedia.org/wiki/Fischer%E2%80%93Tropsch_process  &lt;br /&gt;
&lt;br /&gt;
Fig. The circular economy of OSE is based on wood - to make charcoal, paper, bioplastic, rubber, and fuel.&lt;br /&gt;
&lt;br /&gt;
Cellulose acetate is a bioplastic that is easily made from the most abundant organic polymer in the world - cellulose. It can be made readily from trees. Did you know that wood fibers can be converted to this bioplastic by reacting these fibers - with glacial acetic acid? The product is 3D&lt;br /&gt;
&lt;br /&gt;
printable.http://www.designforcraft.com/new-materials-for-3d-printing-cellulose-acetate/  You can make windows with it.http://nvlpubs.nist.gov/nistpubs/jres/19/jresv19n4p367_A1b.pdf  Instead of trees, one can use any source of cellulose - paper, cotton, straw, or other cellulose materials. &lt;br /&gt;
&lt;br /&gt;
Straw and wood are thus very important in the overall product ecology for making fuel pellets, insulation for the Seed Eco-Home (with borax), strawboard, charcoal, paper,  steel (charcoal with iron ore), and bioplastics.&lt;br /&gt;
&lt;br /&gt;
Polylactic Acid, or PLA, is the most popular bioplastic used in 3D printing. It can be derived from bacterial fermentation of sugar - and is thus an accessible technology within the GVCS.&lt;br /&gt;
&lt;br /&gt;
Polyhydroxyalkanoate (PHA) or polyhydroxybutyrate (PHB) bioplastic polyesters are considered the best candidates to replace the current petroleum-based plastics due to their durability in use and wide spectrum of properties. https://www.intechopen.com/books/biotechnology-of-biopolymers/conversion-of-biomass-into-bioplastics-and-their-potential-environmental-impacts  They are made by bacteria from sugar or starch at an efficiency of up to 80% of bacterial cell mass.https://www.intechopen.com/books/biotechnology-of-biopolymers/conversion-of-biomass-into-bioplastics-and-their-potential-environmental-impacts  Some PHAs are elastomers. Thus - it is realistic to include rubber production for tires - from sugar or starch - within the industrial ecology of the GVCS. Unlike latex resin from dandelion roots - which can be used to produce thermoset plastics - PHA rubber is thermoplastic, so it can be recycled easily. Both PHA rubber and dandelion root rubber can be grown anywhere - thus removing the strategic importance of tropical rubber tree plantations. It appears that PHA rubber is more viable from the decentralization perspective. Wood, broken with acid to simpler sugars - can also be used a feedstock for PHA - thus making PHA rubber production possible anywhere in the world. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4964529/   However, woody crop can compete with food crops - so we once again emphasize perennial polycultures as ways to produce food, fuel, and fiber. With perennials, it is also easier to use degraded lands, which can be regenerated back to fertility and health when annual crops are removed from the equation.&lt;br /&gt;
&lt;br /&gt;
In addition to sugar and cellulose, starch from common sources such as potatoes or corn can be polymerized readily in the kitchen. For example, mixing vinegar and glycerine with the starch makes a bioplastic.http://opensourceecology.org/wiki/Starch_Bioplastic   This is the easiest route  that can be used for 3D printing&lt;br /&gt;
&lt;br /&gt;
The bioplastic extruder has 2 main functions: one is to perform extrusions directly - or to produce intermediate 3D printer filament which is then used to 3D print final objects. For the latter, we are currently building upon two open source projects working on plastic extruders: the Lyman Filament Extruder,http://opensourceecology.org/wiki/Lyman_Filament_Extruder  and the Thunderhead Filament Extruder from Tech For Trade.http://opensourceecology.org/wiki/TechforTrade  These are simple versions of plastic extruders - which if scaled up and made more robust - can produce not only 3D printing filament, but larger extrusions.&lt;br /&gt;
&lt;br /&gt;
==3D Scanner==&lt;br /&gt;
&lt;br /&gt;
The 3D scanner allows for scanning of 3D objects to produce Computer Aided Design (CAD) models for reverse engineering. This is very useful - as we can take existing parts and digitize them for use as editable CAD models. A single camera can be used for photogrammetry, which is a computational technique for converting a set of pictures of an object taken from multiple angles into a 3D object.http://opensourceecology.org/wiki/Open_Source_Photogrammetry There is a number of open source programs that can do this. A 3D digital object can also be generated using multiple cameras, laser beams, or other light sources reflected from an object. As the simplest route, OSE  will build on existing work to develop the toolchain and procedure for photogrammetry - as that requires no hardware outside of a simple camera and a computer to process the images. If markers are used on objects, accurate CAD can be generated with proper dimensions. &lt;br /&gt;
&lt;br /&gt;
It gets more interesting: we can 3D scan internal features, too. This is known as industrial Computed Tomography (CAT) - essentially - a CAT scan for metal objects. By using an x-ray or gamma ray source - and then photographing an image - we can build a low-cost DIY CAT scanner.https://www.youtube.com/watch?time_continue=25&amp;amp;v=hF3V-GHiJ78  http://www.tricorderproject.org/blog/tag/openct/  Combined with an open source code base for image processing  from CERN, 3D industrial tomography scans can be obtained.https://home.cern/cern-people/updates/2016/09/new-open-source-medical-imaging-tools  &lt;br /&gt;
&lt;br /&gt;
==CNC Circuit Mill + Small Laser Cutter==&lt;br /&gt;
&lt;br /&gt;
We have already prototyped a circuit mill - the D3D CNC Circuit Mill.http://opensourceecology.org/wiki/D3D_CNC_Circuit_Mill  This shows a great example of the Unversal CNC axis modularity - where we have used the same motion system as in the 3D printer - but now strengthened the motion system by doubling the x axis to hold a small router. While the 3D printer is a non-contact manufacturing method - the circuit mill requires that the axes withstand contact forces of the milling operation. The strong, steel space frame of the D3D platform can handle these forces.&lt;br /&gt;
&lt;br /&gt;
Furthermore, other tool heads can be used on the Universal Axis. One useful example is a small 4W laser cutter, which cut up to ¼” plywood for prototyping purposes.&lt;br /&gt;
&lt;br /&gt;
Fig. The OSE CNC circuit mill and example circuits produced. The Router Tool Head is one of many tool heads that can be used on the Universal Axis system. A small laser is another, and can be retrofitted readily. The laser cutter toolhead allows for cutting cardboard for rapid prototyping. (4-picture - mill+product, laser+product)&lt;br /&gt;
&lt;br /&gt;
Prototyping with a laser cutter is important to the GVCS because the laser cutter can simulate the cutting that is typically done with a CNC torch table. Just like the CNC torch table typically cuts ½” thick flat parts out of sheet steel - the small laser cutter can cut parts out of paper stock. These parts can then be glued or fit together - just like the CNC-torch-cut metal parts are welded to make real-life 3D machines such as the CEB Press.&lt;br /&gt;
&lt;br /&gt;
Fig. Flat metal is used to generate 3D objects by welding. We thus use 2D cutting to create 3D objects.&lt;br /&gt;
&lt;br /&gt;
An open source project for a larger laser cutter - the 100W Lasersaur - is already well-developed. We can use this platform to build upon as well, to reduce cost from its current $7k to something more on the scale of $3k for a large format laser cutter. The Universal Axis could be applied here, such that only the laser system ($2000) remains as a significant cost - and the rest of the system is ($1000). This would be another great application of the Universal Axis to show its flexibility.&lt;br /&gt;
&lt;br /&gt;
Another useful example of a practical tool-head is a ceramic 3D printer head - which is an extruder for clay materials that can be fired to make functional ceramics. Examples of very useful ceramics are insulators and pottery - especially stovetop cookware made of flameware clay - which can replace commercial cookware and provide artistry in the open source Seed Eco-Home kitchen.&lt;br /&gt;
&lt;br /&gt;
Fig. The ceramic print head allows for the production of practical objects such as pots and pans for cooking, bringing artistry back into the kitchen.&lt;br /&gt;
&lt;br /&gt;
Collaborative Prototyping + Model Kits + Product Ideas + The Open Source Everything Store&lt;br /&gt;
&lt;br /&gt;
With access to the OSE Developer Kit - 3D printer, CNC Circuit Mill, and Laser Cutter - all as different tool heads on the same Universal Axis system - collaborators access a powerful capacity to prototype the larger machines of OSE. Using these tools, accurate scale models can be built. This can extend the collaboration capacity on OSE machine development significantly. There are 4 major ways that collaborative prototyping can be done using the 3-in-1 Universal Axis machine. &lt;br /&gt;
&lt;br /&gt;
First, there is collaboration is CAD verification. Computer Aided Design (CAD) is used in the OSE design process in order to save countless hours during the build. In a proper design process, it is easier to design in virtual CAD - and figure out how everything fits together - rather than going straight to a build and having to fit everything on the fly. The ability to model accurately in CAD is the power that allows OSE to do builds on the scale of a day - as opposed to weeks. However - this works only if the CAD is accurate, because if the CAD drafting is not accurate, it may be impossible to build a machine. CAD quality depends on the skill of the draftsperson. For this reason, it is important to verify the CAD as one of the steps that takes place prior to a build. If mistakes are not caught prior to the build, time and materials are wasted, people can get frustrated, and schedules are delayed.&lt;br /&gt;
&lt;br /&gt;
How do we guarantee that a machine can be built as drafted? With an accurate scale model. First, we must make sure that the CAD of individual parts is correct. This can be assured when accurate CAD files are available - whether the files are generated from measurements, provided by manufacturers, or 3D scanned with the open source 3D scanner. Second, we can verify the actual buildability. This can be done by laser cutting from paper the parts that would be CNC Cut from steel, and then 3D printing the components that we would otherwise get off-the-shelf. For the 3D printing - it is critical that we print every single part - up to bolts and nuts - so the entire assembly we can verify every single step of the build.&lt;br /&gt;
&lt;br /&gt;
This leads to the second use of collaborative prototyping - producing build instructional manuals and videos using the scale models. This allows contributors all over the world to produce meaningful content - without requiring that the contributors have access to a workshop. Since qulaity intstructionals production requires as much effort as the design work - this is another way to contribute to a large, parallel development effort.&lt;br /&gt;
&lt;br /&gt;
The third route to collaborative prototyping is the production of Model Kits for actual products. For example, the Seed Eco-Home lends itself very well for such modeling. Another company, Arckit (ref), is a good model for how we can design the model kit for the OSE’s collaboration with the Open Building Institute.&lt;br /&gt;
&lt;br /&gt;
Fig. Arckit is a great example for modeling. In the OBI case, the models correspond to real building panels and real build procedures. This makes the OBI Architecture Kit a tangible way for people to get involved in meaningful design of future house models.&lt;br /&gt;
&lt;br /&gt;
The OBI Architecture Kit lends itself well to 3D printing as well as laser cutting. 3D printed parts would snap together like Lego blocks.&lt;br /&gt;
&lt;br /&gt;
Another model kit that would be very useful to GVCS prototyping is the Machine Build Kit -  a kit for producing tractors, heavy equipment, and other automated machines. Combined with the OBI Arch Kit for buildings - this would produce the Civiliation Model Kit. The concept for the Machine Build Bit is a mixture of Lego Mindstorms, MakeBlock, Erector Set, Capsela, Box Beam Sourcebook, and Solar Micro Power Cube (all refs) - so that the system can run on solar power. The value proposition is that the kit would once again be based on real buildable parts - thus extending its use from childsplay to real design work.&lt;br /&gt;
&lt;br /&gt;
The OSE Developer Kit + Model Kits pave the way for the 4th route to collaborative prototyping - that of developing open source enterprise. These 2 kits are products in themselves - and can be used as the basis for collaborative business development of distributive enterprise (ref). The concept here revolves around reaching the $1T tipping point for the open source economy - the point at which mainstream adoption of open source economics is likely ($1T is calculated as the 10% tipping point at which viral adoption of open source economics can occur. This coincides with the next Enlightenment of humanity - see Tipping Point on the wiki - http://opensourceecology.org/wiki/The_Tipping_Point  ). This is as large as the combined revenue of Apple ($229B), Google ($79B), FB ($41B), Amazon ($178B), and Walmart ($486B) combined (Microsoft ($90B) - not includes so total is $1T.) - the latter being the single largest corporation in the world.&lt;br /&gt;
&lt;br /&gt;
OSE’s distributive enterprise approach to the tipping point is distributive. The core of OSE’s economic theory is that, by definition, a distributive enterprise serves its customers more effectively than any proprietary enterprise. Thus, a DE has a high likelihood of deposing the corporation http://opensourceecology.org/wiki/The_Corporation  as the dominant societal institution, replacing it with the next phase of the human economy - the open source economy. The transition is in our view likely - because the goal of a distributive enterprise is to produce free enterprise - defined as  distributing wealth most equitably. Current economic paradigms do not internalize distribution in their economic models. The next economy is achievable via full cost accounting and zero competitive waste, thereby achieving zero marginal cost (ref ZMCS). This proposition is simple to grasp, but most challenging to execute. We are not interested in DE as an ideology - but as a pragmatic proposition that simply meets needs more effectively - in an integrated sense -  than current models.&lt;br /&gt;
&lt;br /&gt;
The ask for distributive enterprise is to create the Open Source Everything Store - a networked and collaborative store based on Open Source Microfactories. That is - for people to collaborate on open source product development as a massive parallel effort. Decentralized, distributed, networked production is not a new idea - many people love and claim the idea as their own. To date no successful, economically-viable implementation exists, and certainly not open source. There were many attempts, from the FabLab, Local Motors, 1000 Garages, Ponoko - but none are both distributed and open source. The FabLab is a distributed microfactory concept, but none of its machines are currently open source. FabLabs are are externally funded, and none are used to run a successful business. Local Motors works on distributed production, but their designs and microfactory tools are not open source. 1000 Garages appears stalled. Ponoko and many operations like Ponoko are available. They are successful enterprises, but they do not use open source production tools or software. None of these projects provide open source enterprise information. Perhaps the best examples are 2: first, Lulzbot, which shares its machine designs and enterprise blueprints (blog post from 2014 visit, google Distributive Enterprise) - which makes it a fully open source hardware company - but it has a centralized business model. Second, there is the poster child RepRap project - which is the design/collaboration repository for open source 3D printers. RepRap is responsible for producing most of the consumer 3D printing industry’s companies - both open source and proprietary. (ref) However, RepRap in itself does not have a revenue model. Our own work is also based on the RepRap - it’s the basis that saved us hundreds of development hours - as we could simply build upon their designs. We do have a successfully-demonstrated revenue model of ongoing Extreme Manufacturing workshops.&lt;br /&gt;
&lt;br /&gt;
For The Open Source Everything Store (TOSES), any product developed must include open source blueprints, as well as open source enterprise documentation. Assets such as marketing materials, revenue models, business plans, projections, and entrepreneurship training - among others - must be included to facilitate startup by others. For successful startup - the enterprises themselves must be tested and proven. Thus, case studies of projections, actual revenue, and growth must be included. &lt;br /&gt;
&lt;br /&gt;
With as small an infrastructure as a Personal Microfactory with 3D printing, the CNC circuit mill, laser cutter, filament extruder, and off-shelf components - production of many valuable products can be distributed far and wide. Moreover, open design allows for extended product lifetime - as parts can be upgraded, modifications can be 3D printed, and breakages fixed with readily-accessible parts.  The success of TOSES  revolves around a massive parallel open source product development process - resulting in best-in-class products. These products are then produced by distributed players. Thus, a networked effort could reach substantial distributed production - and distributed sales volumes on the scale of Amazon. &lt;br /&gt;
&lt;br /&gt;
Our claim is that Distributive Enterprise has a good chance of succeeding because of its distributive nature. The cost structure of distributive development is efficient - as it relies on an open source process. We are assuming here that the zero marginal cost prediction - that everything trends to zero marginal cost - which is the competitive advantage of TOSES. However, zereo marginal cost is inherently impossible within the current system. The profit motive of the corporation prevents zero marginal cost, and leads to a permanent inefficiency in human economics. This can be resolved only by a transition away from the traditional corporate IPO form (ref). This is the reason why OSE proposes that a transition to the open source economy is inevitable. However, leading economic theorists such as George Gilder claim that human constructs are not inevitable - they have to be created. Thus, it remains up to human will to decide whether we would like to implement true-cost accounting to transition to the open source economy.&lt;br /&gt;
&lt;br /&gt;
The choice is up to us, and as such we are working on the DE model. Once open source product and enterprise blueprints are available - it means that everyone has access to them. This indicates that efficient production can be distributed into a networked form, which can gobble up Amazon and Walmart. Such a transition to the true-cost accounting economy is the promise of open source economics.&lt;br /&gt;
&lt;br /&gt;
In practice, this requires that open source microfactories, as well as open source materials production facilities - are distributed far and wide. These take abundant natural resources and convert them to a modern standard of living in a distributed way. People can produce with their personal microfactories. Using the 3D printer, circuit mill, laser cutter, and filament extruder - and off-shelf components - people can produce many household goods, electronic gadgets, toys, tools, kitchenware, small appliances, lab equipment (ref), and many others.  The size of the plastic industry alone is $2T - and the size of the injection molding industry is about $100B. Between vaccuum cleaners ($1B), consumer 3D printers ($1B),  cordless drills ($1B in the USA alone), drones, phones, cameras - the market size for those goods is on the order of hundreds of billions of dollars worldwide.  The current limit is 20% of GDP - the manufacturing sector of the economy - or about $16T.&lt;br /&gt;
&lt;br /&gt;
The centralized factory can become obsolete, and many parts of global resource flows can become localized. Specifically - as resource constraints to longer fuel resource conflicts and poverty - humans as a whole have - for the first time in world history - a chance for collective evolution. That simply means that the leading preoccupation transitions from making a living, surviving, or paying off debt - to thriving. This means that the multidisciplinary genius will become much more common - as society reaches a new level. An Einstein could be born every minute. (That makes it 1/250 - or 0.4% of the population.) This means that we transcend William Gibson’s — &#039;The future is already here – it&#039;s just not evenly distributed”. This means that most people will gain access to significant improvement in their quality of life. But this is also not a state of coerced equality as in communism - there will always be outliers who are more ambitious or skilled. But all have a good oportunity to thrive. &lt;br /&gt;
&lt;br /&gt;
CNC Torch and Larger Machines: Heavy Duty CNC Machining&lt;br /&gt;
&lt;br /&gt;
==CNC Torch Table==&lt;br /&gt;
&lt;br /&gt;
The universal axis can handle much larger forces - up to one thousand pounds - when it is scaled up. The universal axis has aleady been used with the 3D Printer and the CNC circuit mill. http://opensourceecology.org/wiki/Universal_CNC_Axis   &lt;br /&gt;
&lt;br /&gt;
We have already built a prototype of the CNC torch table using the Universal Axis, scaled up to a 2x3 meter working area:&lt;br /&gt;
&lt;br /&gt;
Fig: CNC Torch Table build workshop results. (https://www.facebook.com/marcin.jakubowski.378/posts/10213076897374250) &lt;br /&gt;
&lt;br /&gt;
The CNC Torch Table is near release status, and it will be the critical machine used in digital fabrication. The CNC Torch table will be used to cut all metal from flat sheets, which are then welded into 3D machines such as the brick press and tractor. The CNC Torch Table will also be used for cutting holes in 4” square tubing - which is our characteristic life-size erector set design.&lt;br /&gt;
&lt;br /&gt;
Typically, acetylene is used as a cutting gas. In the OSE case, the CNC torch table integrates with the oxyhydrogen production - where water is split into hydrogen and oxygen using electrolysis. These hydrogen and oxygen gases are used as the cutting gases. Oxyhydrogen cutting has been in use prior to the discovery of oxyacetylene cutting in 1903 https://en.wikipedia.org/wiki/Oxy-fuel_welding_and_cutting  - and was preferred for 2x the cutting speed with thick metal. Currently, oxyhydrogen is use whenever a clean cut is required. Otherwise, the gas is 2x as expensive as acetylene. The advantages of hydrogen are the ability to cut aluminum and stainless steel, which acetylene cannot do. Furthermore, if the open source oxyhydrogen generator is used with PV electricity at 1.5 cents per kWhr, then the cost of the gas should go down to about 5x lower than acetylene. Given these advantages, it is interesting to see that oxyhydrogen cutting is not used more commonly in the workshop. The apparent reason for this appears to be the lower price of fossil-fuel derived acetylene. Off-shelf on-demand oxyhydrogen generators appear to be expensive, so they would benefit greatly from being open-sourced. https://www.alibaba.com/product-detail/Gas-generation-equipment-for-oxgen-hydrogen_1950398042.html?spm=a2700.7724838.2017115.380.1b0840b43VI2AU  Hydrogen generators which can produce enough gas for cutting ½” steel are  are available for around $300, not including power supply. http://opensourceecology.org/wiki/Oxyhydrogen_Generator_Cost &lt;br /&gt;
&lt;br /&gt;
The OSE CNC torch table system includes a water bed to minimize smoke and prevent steel from warping while cutting, automatic height control which follows the surface of the metal for optimal cutting, an automatic ignitor, automatic gas control, open source controller, and open source controller software. Each of these piecces has been tested separately, and now we are putting the entire system together to a product that from 2018 onwards will be used to cut all steel for OSE in house. We cut steel for frames of the 3D printer, metal for the brick press, tractor, and just about every other GVCS tool.&lt;br /&gt;
&lt;br /&gt;
==Heavy Duty CNC Multimachine==&lt;br /&gt;
&lt;br /&gt;
The CNC Multimachine is a mill, drill, lathe and other tools in one machine, designed for modularity and flexibility, including rotary indexing and a grinding attachments. It can be used to produce engines and hydraulic motors, threaded parts such as bolts and pipe threads, as well as myriad other parts. The lathe has historically been the cornerstone of precision machining, and is a critical tool in civilization.  It is also another application of the OSE Universal Axis system - using the 2” rod size.&lt;br /&gt;
&lt;br /&gt;
Two other GVCS machines - the induction furnace which melts scrap metal to make virgin steel -  and the Mill which makes Rods and Wire - provide feedstocks for the CNC Multimachine.&lt;br /&gt;
&lt;br /&gt;
Fig. The 2” Universal axis can produce parts with accuracy of 10 microns, based on the deflection of 2” rods with 200 lb of force. This image shows the size comparison between the 2” version - and the 1” and 5/16” versions. The belt drive system can be identical to the smaller machines.&lt;br /&gt;
&lt;br /&gt;
We are interested in developing a core set of modules for a heavy duty machine - including mill, drill and lathe, with rotary and angle tables, plus capacity to function as a screw machine for making threads and bolts. We also include internal threads splines. &lt;br /&gt;
&lt;br /&gt;
Just like with the OBI Arch Kit (make sure reference is correct to rapid prototyping above), the Multimachine Construction Set will allow for modeling with 3D printed parts, which will correspond directly to real life - and thus serve as an educational kit and product. Together with the Multimachine Design Guide and FreeCAD workbench, people will be enabled to build their own multimachines and screw machines.&lt;br /&gt;
&lt;br /&gt;
For the 2” universal axis system, the practical limit is 400 lb of tool force with 0.001 precision and GT2 belt drive. For higher tooling forces, we must use lead screws instead of belts.&lt;br /&gt;
&lt;br /&gt;
The goal of the CNC multimachine is to produce electric motors, hydraulic motors, engines, cylinders, and valve blocks, among others. With a grinder attachment, the idea is to be able to achieve high precision, down to 0.0005, which is the positioning accuracy of the stepper motors at 16 microstepping and 1” GT2 pulleys.&lt;br /&gt;
&lt;br /&gt;
Using the Universal Axis, CNC linear motion control, and CNC rotary chuck control - we can get a wide array of functionality of a screw machine for making various precision parts. With a surface grinder, we can get precision parts down to 25 microns of tolerance. If we build a precision CNC surface grinder, then we can achieve up to 1 micron accuracy for making air bearings.https://www.youtube.com/watch?v=sFrVdoOhu1Q  Air bearings open the possibility of lubrication-free engines and high pressure pumps for storing hydrogen and a prerequisite for certain clean-room semiconductor manufacturing.&lt;br /&gt;
&lt;br /&gt;
==Robotic Arm - trainable for welding + 3D printing==&lt;br /&gt;
&lt;br /&gt;
The robotic arm is a powerful manufacturing tool as it is can move almost as flexibly as a human arm - but with increased precision and strength. Practical tasks that a robotic arm can accomplish depend on the end effector or tool that the arm is holding. For the GVCS, two good applications include automated welding and 3D metal printing using a MIG or TIG welder.&lt;br /&gt;
&lt;br /&gt;
Fig. Robotic welding - [nice pic] is useful for high quality welding to assist the open source renaissance woman. Spot welding or wire welding can be used.&lt;br /&gt;
&lt;br /&gt;
A useful application of robotic arms emerges from trainable robotic arms. Trainable robotic arms are arms which a human operator can train to move as needed. This eliminates complex programming tasks, making robotic collaborators accessible to the general public. An open source software platform already exists for robotic arms in the Robotic Operating System (ROS) project, including trainability.http://moveit.ros.org/  - such that the open source trainable industrial robot is around the corner by building on existing prior art. &lt;br /&gt;
&lt;br /&gt;
==Induction Furnace==&lt;br /&gt;
&lt;br /&gt;
An induction furnace is a device use to melt metal.  Metal can then be recycled - from scrap to useful stock. The advantage of the induction furnace over any other means of melting metal is a clean, energy-efficient and well-controllable melting process. In a typical induction furnace, a water-cooled copper coil with alternating current induces a current in a crucible of metal - hence the name Induction furnace - and that current heats up and melts the metal. Due to the heat being generated within the work piece, energy transfer is extremely efficient.&lt;br /&gt;
&lt;br /&gt;
Fig. In an induction furnace&lt;br /&gt;
&lt;br /&gt;
The induction furnace brings us from the stone and wood age - when stone and wood were the most common materials for making houses and machines - into the iron age - which is synonymous with the industrial age and modern civilization.  &lt;br /&gt;
&lt;br /&gt;
It may be said that modern civilization has culminated with the production of ball bearings. Bearings are a critical component that allows for engines, turbines of modern power to work - and precision machines that use precision ball bearings are used to manufacture these machine. Finally,  vacuum pumps and precision instruments - necessary in semiconductor manufacturing - depend on the use of bearings. As such, the information age today also relies on ball bearings - a combination of material science and precision manufacturing.&lt;br /&gt;
&lt;br /&gt;
==Metal Rolling, Rod &amp;amp; Wire Mill==&lt;br /&gt;
The induction furnace can be used in metal casting, where round rods or billets are cast and then used as feedstocks for metal rolling.&lt;br /&gt;
&lt;br /&gt;
Metal rolling uses rolling dies to shape metal into various profiles, from flat, to round, to angled. &lt;br /&gt;
&lt;br /&gt;
Fig. Metal rolling uses dies of various shapes to produce final stell shapes.&lt;br /&gt;
&lt;br /&gt;
Rolling of thin rounds - or rods - around dies and pulleys - is used to elongate and thin the rounds results in wire - a fundamental building block of civilization. Wire is used for house electrical wiring, suspension,  or fencing.&lt;br /&gt;
&lt;br /&gt;
Fig. A wire drawing machine starts from rod and stretches it to wire through a number of dies. The modular open source version can take rod and turn it into wire of any diameter.&lt;br /&gt;
&lt;br /&gt;
Metal rolling that occurs above the crystallization temperature (700C) is called hot rolling - and it takes less energy to do so as the metal is pliable. Cold rolling occurs at room temperature, and therefore requires more energy to deform the metal - but it also provides more accurate dimensions in the metal.&lt;br /&gt;
 &lt;br /&gt;
==Forging, Ironworker==&lt;br /&gt;
&lt;br /&gt;
The press forge is a heavy duty press than can be used to squeeze metal like butter. When metal is hot, it can be deformed into useful shapes by using a die. Bolt heads are made this way.&lt;br /&gt;
&lt;br /&gt;
Forges can take the form of press, drop, or roll rolling - preferably using the induction furnace for efficient forging. Cold forging may also be done, but that requires larger force for a given deformation.&lt;br /&gt;
&lt;br /&gt;
Forging is useful but the disadvantage is using specialized forming shapes or dies. Thus, the preferable route to forging would in many cases be subtractive machining, metal 3D printing,  or welding - as these are general-purpose procedures that do not require custom forms or dies.&lt;br /&gt;
&lt;br /&gt;
Fig. The press forge can shape hot or cold metal like butter.&lt;br /&gt;
&lt;br /&gt;
==Plasma Cutter, Welder==&lt;br /&gt;
&lt;br /&gt;
The plasma cutter, welder, and induction furnace are high-power electronics that use modern technology for efficiency. By using transistors and inverter circuits instead of large transformers, they can be light-weight and low cost - as the cost of power transistors is 10 cents/kW of power handling ability. This means that the simplest welder circuits can cost only a few dollars in electronic components (not counting wiring, structure, and the balance of system) to get industrial welders on the scale of 10kW (500Amps).&lt;br /&gt;
&lt;br /&gt;
Fig. Diagram of a welder. From first principles, a welder includes power handling electronics, wires, a case, cooling fan, and a welding gun with an electrode, and shielding gas for high quality welds.  In the simplest case - a tungsten electrode creates an arc to the metal and melts the metal, without using filler. This is an example of autogenous welding, where no welding rod or wire is required.  Welding is not complicated - the simplest electric arc welder is a 12V battery connected to a welding rod.&lt;br /&gt;
&lt;br /&gt;
A plasma cutter is a transistor-based power electronic device that cuts conductive metals with a plasma - or ionized gas.  The plasma cutter creates ionized air between an electrode and a work piece. The plasma heats the metal. By directing a focused stream of air around that plasma through a nozzle, the heated metal is oxidized and blown away, creating a clean cut. For comparison,  cut quality  in order of improvement is plasma cutting, oxy-fuel, waterjet, and laser cutting.&lt;br /&gt;
&lt;br /&gt;
Fig. Cut width - or kerf - of plasma, oxyfuel, waterjet, and laser cutting.&lt;br /&gt;
&lt;br /&gt;
Both the plasma cutter and welder are similar to each other. They have similar power electronic circuits.  For a welder or plasma cutter, the main difference is in the gun and electrodes. The gun in both cases has a large copper power wire and a gas line for shielding. For the MIG welder, it also has wire feed. The electrode is tungsten for the TIG welder and plasma cutter, and consumable welding wire for the MIG.&lt;br /&gt;
&lt;br /&gt;
More Power Electronics&lt;br /&gt;
&lt;br /&gt;
Is EDM practical? EDM is a high-voltage spark erosion system for cutting thick metals - where a moving wire at 10,000VDC spark-erodes metals as tiny sparks are established between the wire and metal to be cut. This system is insulated&lt;br /&gt;

Fig 1. The Tractor, Microtractor, Microcombine, Universal Seeder, Spader, Hay Cutter, Hay Rake, Baler, and Dairy Milker, and a Bakery Oven are critical tools of the $8T food industry.&lt;br /&gt;
&lt;br /&gt;
==Tractor, MicroTractor, Bulldozer and Power Cubes==&lt;br /&gt;
&lt;br /&gt;
The tractor is a cornerstone of a farm, construction, or other materials production industries. A tractor has the traction to pull things, and to do utility work with variou implements that can be added to a tractor and use the tractor’s mechanical power through a Power Take-off (PTO). As such, the tractor can be a swiss army knife of heavy duty work. For the smaller individual or home scale, we have the MicroTractor in the set, which is a small, walk-behind or ride-on tractor at the 16-32 hp size that can perform many gardening and utility functions and can fit in a smaller areas where a large tractor would be impractical. If we go up in scale - use a stronger frame and at least 64 hp, and add a bulldozer blade to the tractor - then we have a bulldozer.&lt;br /&gt;
&lt;br /&gt;
The tractor is a machine on the scale of 50-320 hp in the GVCS ecosystem, and unlike traditional tractors, we focus on modular power. We currently use small 16 hp engine units at $17/hp (ref), which is the lowest cost way to obtain engine power, while making maintenance very easy. Like in nature where a tree is made of many branches, our tractor is made of many small engine units. This way, the same design pattern can be used in the 16 hp tractor as in the 320 hp tractor. The price for using larger diesel engines is 2-4 times larger.  &amp;lt;ref&amp;gt;http://opensourceecology.org/wiki/Diesel_Engine_Cost &amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
By using the modularity concept, we create our typical construction set approach for heavy machines. For example, if a large tractor frame is fitted with a bulldozer blade - then we don’t require a separate bulldozer in addition to a tractor. This saves a lot of resources - making technology significantly lower cost to maintain. Exploring the limits of modularity, we found that it is much less expensive to scale our machines usig modular and overbuilt parts that make sense both for small and large machines. For example, we can use 4 of our identical track units, each rated for up to 80 hp - Our track unit, for example, allows for a $30k version &amp;lt;ref&amp;gt; http://opensourceecology.org/wiki/Modular_Track_Unit_v18.01&amp;lt;/ref&amp;gt; that matches the traction of a Cat D7 - a sizeable cost savings comprd to a base price of ½ a million. &amp;lt;ref&amp;gt;https://www.caranddriver.com/reviews/caterpillar-d7e-feature-test &amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Fig. Pattern Language for a Tractor - up to automated control.&lt;br /&gt;
&lt;br /&gt;
The key is making it easy and quick to interchange parts - from small parts to large implements. This is a great challenge for advanced industrial design.&lt;br /&gt;
&lt;br /&gt;
Fig. Industrial smaller parallel and trained configuration. OSE machines can be designed like this, but higher flexibility of the OSE platform can allow for an improved configuration.&lt;br /&gt;
&lt;br /&gt;
Fig. The flexibility of a modular OSE tractor. The modular OSE tractor can be built from the same components, but apply to 16 hp or 320 hp machines while using the same over-engineered components such as the ½” thick steel tracks &amp;lt;ref&amp;gt;Current design is rated for  rated for 40 hp per track or 80 hp with double drive, . (ref - do calculations) and 3600 lbs or 7200 of pull each. Thus, a four-tracked machine can have 29,000 lb of pulling force with direct drive using our current 15k in-lb motors.&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
==Spader, Seeder, Bulldozer==&lt;br /&gt;
&lt;br /&gt;
Your food today is grown largely by tractor-driven  tilling and seeding, unless you’re a breatharian. Tillage in the OSE system chooses the spader as a more progressive technology compared to the age-old plow. &lt;br /&gt;
&lt;br /&gt;
Fig. (Image of 1800 steam tractor with 50 bottom plow) &lt;br /&gt;
&lt;br /&gt;
The spader works essentially like  a bunch of shovels moving rapidly - which till soil without crating a hardpan typical of the more common plow. Manufacturers claim that spading uses 40% less fuel than plowing - because a spader can combine tilling, harrowing, and planting in one operation. &amp;lt;ref&amp;gt;https://www.farmax.info/PDF/Magazine-Farmax-EN.pdf &amp;lt;/ref&amp;gt; A plow, which drags through the soil, requires a lot of wheel-to-ground  traction, whereas a spader requires very little - thus avoiding soil compaction. It takes a spader under 9 minutes and 2 gallons of fuel per acre of field - such that feeding Dunbar Village &amp;lt;ref&amp;gt;A village of 200 -  based on Dunbar’s number https://en.wikipedia.org/wiki/Dunbar%27s_number &amp;lt;/ref&amp;gt; would take 6 hours to plant for a whole year of crop &amp;lt;ref&amp;gt;Assuming field crops planted with a seeder, not slips like sweet potatoes. http://opensourceecology.org/wiki/Acres_Needed_to_Feed_Dunbar_Village &amp;lt;/ref&amp;gt;Thus, one day to plant, two days to harvest - and the village has food for the year. &lt;br /&gt;
&lt;br /&gt;
The tractor and universal seeder is an example of how we approach multiple purpose machines. The tractor is a large-size swiss army knife for doing many different tasks. The Universal seeder is designed to plant all types of seed, from alfalfa to wheat, to tubers, and to live plants like sweet potato slips. Modifying the device rapidly is key to this flexibility.&lt;br /&gt;
&lt;br /&gt;
Fig. Swiss army knife tractor concept&lt;br /&gt;
&lt;br /&gt;
The point of using powerful machines wisely is that in the OSE perspective of lifetime growth -  life could become easy so we can focus on evolving as humans. Our experiment involves building a college campus where peole live this. When they graduate, they know how to organize a village to spend 2 hours per day working on survival, and then the rest of their life they pursue their highest ideals.&lt;br /&gt;
&lt;br /&gt;
The experimental village thus requires one farmer who is employed 3 days of the year, assuming the equipment does not break down, and generates 30 acres * $20k/acre of sweet potato, and $5k/acre for 10 acres of wheat if that is turned into bread  - or $650k worth of food for the community with direct marketing. That is $27k/hour if baking is automated - a decent pay, but not like the $25k/minute rate of Warren Buffett &amp;lt;ref&amp;gt;http://www.businessinsider.com/what-warren-buffett-makes-per-hour-2013-12  &amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Of course these are unreasonable figures, but they do represent the idea. The only way that customer acquisition and marketing costs do not ruin such ideals is in the case of direct marketing - where the on-site farmer-scientist provides for a captive audience of the Dunbar village. If each person eats about $2600 per year &amp;lt;ref&amp;gt;https://www.google.com/search?q=average+cost+of+food+per+year&amp;amp;oq=average+cost+of+food+per+year&amp;amp;aqs=chrome..69i57j0l5.7243j1j7&amp;amp;client=ubuntu&amp;amp;sourceid=chrome&amp;amp;ie=UTF-8&amp;lt;/ref&amp;gt;, feeding 150 people would involve revenues of $390k - but that would be a full time job. We will look more carefully at the business model for resident farmer agriculture in the Enterprise chapter.&lt;br /&gt;
&lt;br /&gt;
Now it would take more time to do a diversified operation, but this is shown just as a baseline to see what’s possible in terms of the effort.  Several Ph.D.’s can be granted to develop a diversified, 40 acre subscription farm, using open source equipment and a captive market, or Local Food Nodes as part of a distribution platform.  &amp;lt;ref&amp;gt;https://localfoodnodes.org/&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The OSE project will develop such a food enterprise both for its campuses and for the outside community - once all the farming machines are done, the aquaponic greenhouse production is optimized, and derivative food processing tools are developed.&lt;br /&gt;
&lt;br /&gt;
The open source tractor can be built at a cost of $125/hp at a scale of 80 hp, compared to $370-$1000 for other brands. It is useful to understand the basic cost breakdown based on off-the shelf parts:&lt;br /&gt;
&lt;br /&gt;
Fig. Cost breakdown of a tractor by Frame, engine, hydraulics, control, automation, and balance of system - $125/hp. (p590MJ)&lt;br /&gt;
&lt;br /&gt;
The cost advantage is less visible at the 32 hp MicroTrac, at $160 per hp - though but a comparable mahine like the tracked Toro Ding costs around  $1000/hp (ref).&lt;br /&gt;
&lt;br /&gt;
Fig. Microtrac with tooth bar bucket can till your garden, and provide valuable utility work. It is an indidspensible utility machine for any prosumer.&lt;br /&gt;
&lt;br /&gt;
==Hay Cutter, Rake, Baler==&lt;br /&gt;
&lt;br /&gt;
If farm animals are involved, then you need these. Or if you want to move large quantities of materials, then a bale is a useful form: from a bale of hay, brush, cotton, cardboard, or plastic - bales allow large scale moving of materials. Bales of aluminum cans are likewise useful for melting down in your induction furnace. If you are making fuel pellets from biomass, plastic pellets for making 3D printer filament - you will need a baler to make 1 ton bales.&lt;br /&gt;
&lt;br /&gt;
==Dairy Milker== &lt;br /&gt;
For animal husbandry, hay baling stores hay for the winter. Unless you are talking about the fish in your home aquaponic system. Dairy products themselves are $116B &amp;lt;ref&amp;gt;https://www.ibisworld.com/industry-trends/market-research-reports/manufacturing/food/dairy-product-production.html &amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
of the global economy - hence the relevance of the dairy milker. &lt;br /&gt;
&lt;br /&gt;
Table: values of the overall food, dairy, cattle, vegetable markets worldwide.&lt;br /&gt;
Combining the dairy milker with computer vision and automation, we envision a solar robotic milker - our MicroTrac with a milking stall - that drives up to a cow to milk her, and then brings the milk back for storage and processing. This allows field milking without human labor for small diversified robofarms that combine the best of regenerative agriculture with modern tehnology to relocalize farming.&lt;br /&gt;
&lt;br /&gt;
Fig. Robotic milker&lt;br /&gt;
==MicroTrac== &lt;br /&gt;
&lt;br /&gt;
A very interesting use arises with a small, solar, robot tractor - the MicroTrac driven by a solar panel. By adding a $10 Raspberry Pi Zero Controller &amp;lt;ref&amp;gt;https://www.adafruit.com/product/3400?gclid=EAIaIQobChMI2rz0mcnd2gIVCzlpCh3MpQgIEAQYAiABEgKi7_D_BwE&amp;lt;/ref&amp;gt; and a $100 solar panel you can be your robotic tractor - for agriculture and other. You can now mow your lawn automatically, and even pelletize it for fuel for a pellet stove. This is possible because today - advanced microelectronics such as the Raspberry Pi is 100 times faster that the first supercomputer, which cost $9M &amp;lt;ref&amp;gt;https://www.theregister.co.uk/2008/01/05/tob_cray1/ &amp;lt;/ref&amp;gt; in 1975.&lt;br /&gt;
&lt;br /&gt;
Fig. A solar-driven MicroTrac concept with solar panel and $50 arduino controller can provide autonomous agriculture &lt;br /&gt;
&lt;br /&gt;
==Bulldozer==&lt;br /&gt;
&lt;br /&gt;
Now add a bulldozer blade to a beefed up, tracked tractor - and you have one of the most powerful devices for regeneration - or destruction - depending on how you use the machine. Bulldozers are powerful earth moving machines - to build roads, grade house foundations, and in agriculture - to build regenerative earthworks for water and erosion. The biggest example is the 12,000 square miles that have been regreened in China - the Loess Plateau. &amp;lt;ref&amp;gt;John Liu reported on this - http://www.aquinta.org/news/2016/10/6/greening-the-desert  &amp;lt;/ref&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Fig.&#039;&#039;&#039; Loess Plateau reforestation&lt;br /&gt;
&lt;br /&gt;
So, if you ever drove on a road - you used a bulldozer. Maybe not you, but whoever graded the road base. &lt;br /&gt;
&lt;br /&gt;
==Microcombine==&lt;br /&gt;
&lt;br /&gt;
The Microombine is used to harvest grains and seeds of any type. This is the core of human harvests world wide. For the OSE case, we have a much more flexible and modular machine in mind. Based on our module-based aproach, we can use the same drive platform as the tractor&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Fig&#039;&#039;&#039;. Showing the base drive platform that can be used &lt;br /&gt;
&lt;br /&gt;
==Bakery Oven==&lt;br /&gt;
&lt;br /&gt;
Humble bread is a $419B global market https://www.ibisworld.com/industry-trends/global-industry-reports/manufacturing/bakery-goods-manufacturing.html . It is the 12th most popular food in the world. https://www.farmflavor.com/at-home/what-is-the-most-popular-food-in-the-world/  And 49% of Americans eat bread  https://www.smithsonianmag.com/smart-news/each-day-50-percent-america-eats-sandwich-180952972/ . &lt;br /&gt;
&lt;br /&gt;
Now bulldozers, tractors, and combines are all good - but the next step for gobal agriculture is the transition to  perennial polyculture  https://www.youtube.com/watch?v=KpJR2yfLUU0  , with only a small fraction of tillage ramaining.&lt;br /&gt;
&lt;br /&gt;
=Construction - 13 Tools=&lt;br /&gt;
If you want to build a charter city or a smaller campus, you will need construction equipment - and a trencher to put in gigabit internet fiber between the locations.&lt;br /&gt;
&lt;br /&gt;
The tools in the construction part outside of the tractors include the backhoe, trencher, cement mixer, sawmill, CEB press, well-drilling rig, soil pulverizer, hammermill. The universal rotor is a tool used in other sectors of the GVCS - and the SeedHouse is a living machine. &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Fig. 13 tools of the construction part of the Global Village Construction Set.&lt;br /&gt;
&lt;br /&gt;
==Backhoe, Trencher, Cement Mixer==&lt;br /&gt;
&lt;br /&gt;
The backhoe or excavator can be used to dig aquaponic ponds, foundation trenches. It can be used to remove stumps, do trenching, and with a grapple it can be used to lift logs or to hoist heavy objects. Backhoes are relatively simple devices - a set of pivot joints that use hydraulic cylinders for their motion - producing thousands of pounds of digging force at the touch of control levers. There are both side-to-side moving backhoes, but a 360 degree rotating backhoe is much more flexible. The small side to side version can be used on a front quick attach of a tractor.&lt;br /&gt;
&lt;br /&gt;
Fig. OSE backhoe from 2010 https://www.google.com/search?q=ose+backhoe&amp;amp;client=ubuntu&amp;amp;hs=ToH&amp;amp;source=lnms&amp;amp;tbm=isch&amp;amp;sa=X&amp;amp;ved=0ahUKEwjLzZKelOLYAhULbawKHQo-DVwQ_AUICigB&amp;amp;biw=1351&amp;amp;bih=731#imgrc=t8j52U9--mn6BM:  mounted on he original lifetrac, a small one used for water line trenching in 2012 http://opensourceecology.org/wiki/File:Bhp1.jpg , and a larger one from 2013 https://www.youtube.com/playlist?list=PL6Jpysxw3Ty-oH4bggp32PR_rPWr8bKC1 . Next iteration is the 360 degree backhoe with remote control drive to facilitate hydraulic line routing.&lt;br /&gt;
&lt;br /&gt;
The trencher in the original GVCS icon is a wheel trencher. We built 2 prototypes, and the next iteration will be a chain-based trencher based on our favorable experience with oversized chain drive on the bulldozer tracks.&lt;br /&gt;
&lt;br /&gt;
Fig. OSE Trencher http://opensourceecology.org/wiki/Trencher - 2011 and 2013 builds.&lt;br /&gt;
The cement mixer is indispensable. Cement has been used in ancient Rome and in mesoamerican temples. Scotland&#039;s County Cork had 23,000 lime kilns at one time - had one kiln per 80 acres. Wood or coal was used as fuel. http://www.lowtechmagazine.com/2013/09/lime-kilns.html  http://www.chapelgatehome.uk/our-blog   Portland cement took over lime cement in the last 100 years, but lime concrete is favorable in foundations becaue it doesn’t crack as easily as Portland. Using modern appropriate technology, lime cement production in solar microfactories is a viable enterprise at the 1 ton per day scale using an open source microkiln the size of a refrigerator. Limestone goes in one end, and lime comes out the other. With such small appliances costing around $1k, cement production can be distributed - while making cement production carbon neutral, annihilating  the current 5% CO2 emission share of the the concrete industry.https://en.wikipedia.org/wiki/Environmental_impact_of_concrete  This is possible in about 50% of America, where the bedrock is made of limestone. That’s a $10B industry in the USA alone.https://en.wikipedia.org/wiki/Cement_industry_in_the_United_States &lt;br /&gt;
&lt;br /&gt;
The cement fryer - a rotary lime kiln - is much like the cement mixer: a Universal Rotor with a heating element. A rotating pipe heated by PV, and an Arduino microcontroller to measure temperatures and guide the process to efficient completion. While not part of the 50 GVCS technologies, it’s a ready derivative:&lt;br /&gt;
&lt;br /&gt;
Fig. PV of the Open Source Materials Production Facility, a solar Power Cube, a Universal Rotor, metal pipe and an Arduino microcontroller constitute the lime cement maker.&lt;br /&gt;
&lt;br /&gt;
If we want to go to the essence of construction, take the backhoe excavator, chase it with a bulldozer with ripper shanks, and then rock under a site could be extracted to build a pond. This rock, if limestone, is feedstock for your lime kiln. In some places, rock outcroppings make access to limestone easy.&lt;br /&gt;
&lt;br /&gt;
==CEB Press , Soil Pulverizer, and Sawmill==&lt;br /&gt;
&lt;br /&gt;
The Compressed Earth Brick press and sawmill are critical tools for construction in that they produce materials. The CEB Press allows one operator to load raw dirt right from the building site to produce about 5000 bricks in a day - enough for a small house. &lt;br /&gt;
&lt;br /&gt;
Fig. The CEB Press is the first machine that we have prototyped, and it is ready for widespread replication around the world.&lt;br /&gt;
&lt;br /&gt;
We have used the soil pulverizer to prepare soil for pressing CEB blocks. The soil pulverizer was used to both pulverize the soil, and its bucket was used to press bricks for CEB construction.&lt;br /&gt;
&lt;br /&gt;
Fig. Soil pulverizer - Aidan on the tractor + loading the brick press by Yoonseo&lt;br /&gt;
&lt;br /&gt;
Our next step on the CEB press is a full soil conditioner which pulverizes soil, adds cement at a measured quantity of 5%, and then loads the mixture into the CEB press - to allow for production of high quality, stabilized block.&lt;br /&gt;
&lt;br /&gt;
Fig. The soil conditioner accepts raw soil from a tractor loader, mixes a measured amount of cement, and loads the prepared mixture into the CEB press for effective production of stabilized block at 12 cents ( 10 cent cement cost for a 20 lb block, and 2 cents gasoline cost). per block in materials. This means that we can build a 1’ thick CEB wall section for $50 in materials.&lt;br /&gt;
&lt;br /&gt;
The sawmill is a machine that can produce dimensional lumber - a staple of construction. Our sawmill is a variety known as a swing-blade sawmill, which has a single blade that can rotate 90 degrees and make a dimensional piece of lumber by going forward and back on a piece of wood.  We chose the dimensional sawmill for its simplicity over a bandsaw mill, as blade sharpening is much easier - and maintenance is the larger cost of any equipment if that equipment is designed for a lifetime.&lt;br /&gt;
&lt;br /&gt;
The sawmill is a good example of how we can use GVCS product ecologies to reduce complexity and reduce the cost of equipment. We design not just individual machines, but machine ecosystems that feed off one another. We can obtain drastic cost reduction by borrowing existing modules from the GVCS. For our case, it makes sense to design the sawmill as a Bobcat standard quick attach implement. We borrow the tractor as a  quick attach point, so that we do not need a bed upon which the sawmill head would otherwise ride. We borrow 32 hp from the tractor Power Cubes. We also  borrow the hydraulic motor which we attach with hydraulic quick-connect hoses. Thus, we have essentially stripped down the entire sawmill to the long carriage with the cutting head - saving $2k https://www.ebay.com/itm/30hp-Kohler-Engine-1-1-8-D-Command-15Amp-Exmark-CH750-0026/132423001888?epid=26011371639&amp;amp;hash=item1ed506a720:g:4YUAAOSwH2VaS3-h  on the engine, $2k https://sleequipment.com/dovetail-utility-trailer-7x20-with-3500lb-axles.html?fee=8&amp;amp;fep=524834&amp;amp;gclid=EAIaIQobChMIws349azn2AIVBqxpCh1rMwbpEAQYASABEgIeHPD_BwE  on a trailer. The greatest advantage would be the setup time - if designed as a quick attach implement, the sawmill can be taken to a log, rested right by the log, and ready for action - as compared to systems where the carriage base must be set up or the log moved into cutting position. If the sawmill can straddle right over a log or be raised with the loader arms, there is no limit ot the size of log that the mill can handle. &lt;br /&gt;
&lt;br /&gt;
Fig. The simplicity of the OSE swing-blade sawmill involves a long linear track mounted as an implement for the tractor. To provide 3 axes of motion - the loader mounting includes height adjustment (z motion), and a lightweight cantilevered head provides side-to-side motion. The cost of about $1500 is significantly lower than the $15k http://www.dltimbertech.com/dl-180-swing-blade-sawmill-10-x-20.html   minimum for a comparable 32 hp sawmill. (ref)&lt;br /&gt;
&lt;br /&gt;
And the sawdust that we generate can be used as animal bedding, insulation, or it can be pelletized to make fuel pellets.&lt;br /&gt;
&lt;br /&gt;
==Universal Rotor==&lt;br /&gt;
&lt;br /&gt;
The Universal Rotor is a fundamental building block for just about any moving machine. It is a combination of rotary motion and a useful tool-head. As a design pattern consisting of a shaft, bearings, and a motor -  a wide array of working tools can be attached to it - so that the Universal Rotor can constitute a drill, a wind turbine,  a wheel, a hammermill, cement mixer, sawmill - etc  - essentially any machine at any size - from small cordless electric drills to a larger 50kW rotor of a wind turbine. &lt;br /&gt;
The Pelletizer , Chipper/Hammermill, Dimensional Sawmill, Rototiler/Soil Pulverizer, Cement Mixer, Well-Drilling Rig, 50 kW Wind Turbine, Microcombine Thresher, and Bioplastic Extruder are direct applications of the universal rotor, and combined with precision machining structures, the Universal Rotor also include the heavy duty CNC Multimhttps://www.opensourceecology.org/portfolio/pelletizer/achine with lathe, drill press, slow cutoff saw, surface grinder, and other machines of fabrication.&lt;br /&gt;
If we can build a Universal Rotor, a Power Cube, and weld together  a supporting structure - then we have - broadly speaking - built 23 of the 50 machines of the GVCS. For example, if we consider the electric motor - it is a a shaft, 2 bearings, a structure, and the ‘tool head’ could be considered the electrical windings that make the shaft spin. Or, if we consider the metal lathe - a part of the Multimachine - then it is clear that the lathe consists of a heavy shaft, 2 heavy bearings, and the tool-head is a chuck for holding work-pieces.&lt;br /&gt;
&lt;br /&gt;
==12. Well-Drilling Rig and Chipper/Hammermill==&lt;br /&gt;
The well-drilling rig is a machine used to dig deep water wells. It consists of a universal rotor which uses 3” (https://www.aquascience.net/grundfos-10sq05-160-230v-10gpm-1-2hp-230v-2-wire-96160140-3-stainless-steel-submersible-well-pump?gclid=EAIaIQobChMIlt-S3PDn2AIVC6tpCh369g34EAQYASABEgJr__D_BwE. 10’ of this pipe store 4 or 6.5 gallons of water. ) or 4” drill pipe to drill down to a depth of 100m or more using hydraulic rotary drilling. In this method, a stream of water is sent down the pipe during the drilling operation to send up tailings and soften the area of the drill point. A heavy duty hydraulic motor spins the drill rod - and new sections of drill rod are attached one after another. When the operation is done, the drill pipe is left underground and a submersible pump is inserted to pump water from the well.&lt;br /&gt;
Fig. A hydraulic deep well pump drilling system explained. The water swivel is the key part here. Otherwise 3” pipe that can be used as  drill pipe and casign is $12/foot. https://www.discountsteel.com/items/Galvanized_Steel_Pipe.cfm?item_id=172&amp;amp;size_no=11#skus  &lt;br /&gt;
The chipper/hammermill is another application of a universal heavy rotor with swinging or fixed blades. This machine shreds or pulverizes materials, and can be as small or large as needed.&lt;br /&gt;
Fig. Hammermill variations with various blades to chip wood or crush rock. A modified version of a heavy rotor can be a grinder. The scale can be from the largest - shredding cars - to the smallest - with small electric motors - if you have hydraulic drive and electric drive.&lt;br /&gt;
&lt;br /&gt;
==The House - Seed Eco-Home and Aquaponic Greenhouse==&lt;br /&gt;
&lt;br /&gt;
The Seed Eco-Home is a living machine - and becase it is the single largest cost of living today, we dediced to include that in the GVCS. (Initially, the house was not in the GVCS - but it was added as the Microhouse.) The Seed Eco-Home is the culmination of all the construction machines put to use. Homes are  also about  $3T (https://en.wikipedia.org/wiki/Construction#Industry_characteristics - residential construction is about ⅓ of all construction) market worldwide - which if open-sourced, could provide 30 million regenerative housing jobs for open source home building entrepreneurs Earning $100k each per year. This is 30 million potential collaborators - through we need only about 1000 at this time.&lt;br /&gt;
&lt;br /&gt;
The OSE/OBI https://www.openbuildinginstitute.org/  Seed Eco-Home is a an affordable, expandable eco-home that can be built for ⅓ the cost of a typical home, while including ecological features. Rather than building a large house, we propose starting with a seed home, and then growing it as the need arises. &lt;br /&gt;
&lt;br /&gt;
We are pushing ecological limits in our autonomous house design. The house is  off-grid with PV, provides its own cooking fuel from a biodigester, includes roof-top rainwater collection, and grows its own food with an aquaponic greenhouse. Mowed lawn or biomass is used to provide heating biomass pellets for a hydronic stove that is fueled by pellets. The eventual product vision is a house that  produces fuel for cars as compressed biogas or compressed hydrogen - by splitting water. Thus, we are correcting the oil and gas industry with 100% renewable energy, using simple, proven technologies. We are not relying on advancements in battery technology as a prerequisite to sustainable transportation, and by not requiring scarce lithium for batteries, we are aiming for an abundant and environmentally friendly energy future. http://www.kitco.com/ind/Albrecht/2014-12-16-How-Green-is-Lithium.html  We favor rooftop PV plus electrolysis as the preferred route for transportation fuels, where every house becomes a gas station. Using medium pressure electrolyzers that can produce hydrogen up to 33 atmospheres without needing a compressor - we can readily store hydrogen in large propane tanks or higher pressure steel pipe. &lt;br /&gt;

&lt;br /&gt;
Fig. Aquaponic greenhouse glamour shot.&lt;br /&gt;
&lt;br /&gt;
The aquaponic greenhouse is designed to provide a year-round supply of fresh eggs, vegetables, fish, and mushrooms. The goal is to include automated planting with a small Farmbot (https://farm.bot/ . By Shuttleworth Fellow friend Rory Aaronson.), where the resulting deep pots are planted in the  towers. With a 1000 plant growing capacity in the main towers, the greenhouse can provide a robust salad daily, where we plant and harvest 15 plants per day from a small 800 sf greenhouse. A mushroom yield of 1lb is obtained per week from a tower that takes only 1 square foot. We also intend to use automated 3D printed aerial drones for planting seeds directly into towers - a great example of useful product ecology. Local food addresses the issue of food miles, where food travels an average of 1500 miles in the USA before ending up on someone’s plate. https://cuesa.org/learn/how-far-does-your-food-travel-get-your-plate  This is one of the numerous inefficiencies that will be addressed by a more efficient, open source economy. This brings us to transportation.&lt;br /&gt;
&lt;br /&gt;
=Transportation. =&lt;br /&gt;
&lt;br /&gt;
The microcar, truck, electric motor, and hydraulic motor are the 4 GVCS machines directly related to transportation. &lt;br /&gt;
&lt;br /&gt;
The worldwide production of cars is a total of 95M per year, 75% of which is done by the top 15 companies. https://en.wikipedia.org/wiki/Automotive_industry#World_motor_vehicle_production  This lends itself to massive distribution of power. The OSE paradigm proposes instead that there would be on the order of million distributed enterprises - essentially one per 10,000 people. Each facility would produce cars on the scale of dozens or hundreds in the community-supported manufacturing (CSM) scenario. Thus, car producers replace car dealership  - as the producer takes to dealing.  This would go well with a gas station at every home, splitting Seed Eo-Home rooftop water for fuel at a cost of 80 cent per gallon of gasoline equivalent. http://opensourceecology.org/wiki/Hydrogen_Production &lt;br /&gt;
&lt;br /&gt;
Fig. Seed Eco-Home to car fuel infrastructure consists of rooftop water collection, 10kW of PV panels, a storage tank for hydrogen, and compression to 200 bar. Piece of cake if you consider not doing this - wars for oil. This gives us about 100 miles of fuel worth per day in a 100mpg microcar.&lt;br /&gt;
&lt;br /&gt;
==OSE Microcar==&lt;br /&gt;
&lt;br /&gt;
The OSE Microar is a Hydrogen Hybrid Hydraulic (H3) vehicle. Hydrogen is chosen because an internal combustion (ICE) engine running on hydrogen is twice as efficient (40%) as a normal ICE (20%), and only 25% under the 50% efficiency of fuel cells. http://environment.yale.edu/gillingham/hydrogenICE.pdf A hydraulic drive train (71% efficiency) - has a higher efficiency than a continuously variable transmission (60%) for fuel cell electric vehicles - meaning that the humble hydrogen hydraulic car gets a higher mileage than a fuel cell car, at significantly lower cost. At a design weight of only 850 lb, less than ¼ of a typical car, the OSE microcar focuses on moving the passenger, not a large chunk of metal accessory to the core purpose. Lighter cars have a good safety record. Before the S.U.V. boom, the country (USA) had the world&#039;s lowest highway death rate.http://www.nytimes.com/2004/05/05/business/averag e-us-car-is-tipping-scales-at-4000-pounds.html  Additionally, gas mileage for the OSE Microcar is specified for 100mpg. While not as testicular as a Tesla, the OSE specification requires higher self-esteem on the part of the driver to accept acceleration from 0-60 of 12 seconds, as opposed to under 3 seconds for a Tesla Model S.https://en.wikipedia.org/wiki/List_of_fastest_production_cars_by_acceleration&lt;br /&gt;
&lt;br /&gt;
Fig. The OSE Microcar concept.&lt;br /&gt;
&lt;br /&gt;
Are smaller cars safer? This is controversial. https://www.ptua.org.au/myths/smallcar/  Physics says that energy of motion is proportional to v squared, and data shows that 56% of car deaths are single-car collisions. So unless you are going to hit another oncoming car or an immovable object like a large tree, your tiny car of under 1000 lb  has 36x less energy to dissipate than a Chevy Suburban of 6000 lb. And, the lightest car - the Smart Carfortwo at 1800 lb http://driving.ca/hyundai/accent/auto-news/news/these-are-the-ten-lightest-cars-you-can-buy-in-2015  and it certainly does get eaten up in a frontal 2 car collision with a larger car. And crashes took more than 37k lives in the US http://www.iihs.org/iihs/topics/t/general-statistics/fatalityfacts/state-by-state-overview#Crash-types  , with 20-50x more if injuries are counted. http://asirt.org/initiatives/informing-road-users/road-safety-facts/road-crash-statistics (are injuries better or worse in large cars?)&lt;br /&gt;
&lt;br /&gt;
But this is all before self-driving cars enter the scene - which have been tested for 0 driverless car crashes over 1.8 million miles by Google - with 13 fender benders caused by other cars. http://bigthink.com/ideafeed/googles-self-driving-car-is-ridiculously-safe  In other words, the case is there for super-small, super-efficient cars that are robotically controlled. &lt;br /&gt;
&lt;br /&gt;
What we have in mind follows the standard of the 200 mpg fuel efficiency of the VW  L1 first prototype car, at 640 lb weight, 8 hp, top speed of 75 mph, with tandem seating for 2. https://en.wikipedia.org/wiki/Volkswagen_1-litre_car. The efficiency dropped to 170 mpg in a hybrid version - http://gas2.org/2009/09/14/volkswagens-diesel-hybrid-1l-concept-gets-170-mpg-available-by-2013/  If OSE achieves the same with 16 hp instead of 8 hp, and using hydraulics while not needing to go to a hybrid drive-train that apparently reduced its initial mileage performance - then we will have a major victory for open source-  Hydraulic accumulators may be used for peak power.  Plus, we’d like to achieve this with hydrogen as fuel in later versions.&lt;br /&gt;
&lt;br /&gt;
More specifically - our model is an H3E car - including a hybrid electric component.  The hydraulic component is a peak power electric-hydraulic micro-Power Cube of about 40 lb additional weight - powered by the onboard starter battery for its cranking amps.  This additional 30 seconds of a starter battery would double the power of the 16 hp engine - such that burst of energy for passing and sudden acceleration can be achieved easily.&lt;br /&gt;
&lt;br /&gt;
==B The Solar Car==&lt;br /&gt;
&lt;br /&gt;
The Solar Challenge is a fascinating event that shows PV-covered cars traveling 62 mph average across Australia. Granted that the driving is in expensive prototypes ad a sunny country - only in daytime - this still bodes well for the feasibility of solar transportation. The typical cars used are small - surface area of a Toyota Prius - and the OSE version would be twice as large 24x8 feet for 3kW of installed PV + 44 lb Lithium ion batteries + 2.5 kW small engine. http://opensourceecology.org/wiki/Solar_Car This allows for a total of 7kW of continuous power for one hour, or 4 kW total power continuous - at 750 lbs of weight. This just may work - if we 3D print a form frame for carbon fiber layup. 3D printing here may be the enabling technology.&lt;br /&gt;
&lt;br /&gt;
==Truck==&lt;br /&gt;
&lt;br /&gt;
The truck is a medium-size, hydraulic, 80 hp driven vehicle comparable to the Mercedes Unimog. https://en.wikipedia.org/wiki/Unimog  With a design top speed of 62 mph,  a weight of 6550 lb, and a hydraulic power take-off, the OSEmog could function as an agricultural tractor as well. The OSEmog is designed to accept a loader or various implements on the front or back. Using basic hydraulic circuits, the machine would have high and low gear, and speed cotrol via simple flow control valves.&lt;br /&gt;
&lt;br /&gt;
Fig. The OSEmog is a multipurpose truck for carryng loads or operating various implements. With off-the shelf parts, it is designed to be field serviceable, and the working hydraulic fluid can be grown - canola oil with additives.&lt;br /&gt;
&lt;br /&gt;
==Hydraulic and Electric Motors==&lt;br /&gt;
&lt;br /&gt;
Both the car and truck have a choice of using hydraulic or electric drive. The advantages of hydraulics are low-cost, high torque, and simplicity of resulting drive design. Hydraulic motors cost only $10/hp, half that of electric motors - but a typical 40 hp hydraulic motor weighs about 50 lb http://opensourceecology.org/wiki/45.6_Cu_In_Hydraulic_Motor as opposed to about 350 lb https://inverterdrive.com/group/Motors-AC/TECA2-200L-4-Pole-B3-High-Efficiency-AC-Motor-200/ .  Typically electric motors are high speed and need to be geared down - whereas hydraulics can be used largely with direct drive. If high torque electric motors are used - these are more like $100/hp when the controller is included - making the drive system 10x as expensive for larger machines.  Electric motors are sensitive to moisture and dirt, while hydraulics are designed for dirty environments. &lt;br /&gt;
&lt;br /&gt;
We use electric motors and generators - in solar electric power cubes - or in wind turbines. But the flexibility, power, and simplicity of hydraulics is a better choice for practical applications - especially when powered by hydrogen and transmitted by canola oil as the hydraulic fluid.&lt;br /&gt;
&lt;br /&gt;
The electric motor can also be 3D printed, making it fit with the OSE product ecology. &lt;br /&gt;
&lt;br /&gt;
Fig. A proprietary, 3D printed, 600W, 80% efficient electric motor. The equivalent is worthwhile to open-source.&lt;br /&gt;
&lt;br /&gt;
Electric motors can be both linear and rotary. In the linear form, they are known as solenoids - very useful devices that are used to make valves. For automation - we use hydraulic valves to control machines like the brick press - and solenoids are used wherever pneumatic or hydraulic controls are needed. This means any automated system - from the water control in aquaponics to the control of an industrial robot.&lt;br /&gt;
&lt;br /&gt;
The electric motor of interest ranges from a small 5W one to power a cordless drill - to the 50kW scale for use in the 50kW wind turbine.&lt;br /&gt;
&lt;br /&gt;
This brings us to the energy sector.&lt;br /&gt;
&lt;br /&gt;
=Energy Tools=&lt;br /&gt;
&lt;br /&gt;
The sun currently shines 10000 times more power to the earth than the entire civilization uses. The implications are profound: there is no such thing as an energy shortage. Energy scarcity is an imagined problem if we talk about actual availability of energy.&lt;br /&gt;
&lt;br /&gt;
We look at it as- it is a high priority to trap solar energy directly - by effective solar design of buildings (Homes and businesses spend about 50% of their energy on heating and cooling. )- and using photovoltaic energy (Solar Concentrator) to generate electricity locally, with wind (50kW Wind Turbine) wherever possible. For machines, the choice is to use hydrogen, charcoal, and compressed biogas. &lt;br /&gt;
&lt;br /&gt;
Hydrogen is by far the most efficient and clean when derived from water (as opposed to refining from oil and gas).  The process gives 0 pollution, and the product of hydrogen combustion is water. The OSE platform calls for provent internal combustion engines running on hydrogen as an immediately executable transition to a renewable energy future in transportation. Leading research institutes, such as the Rocky Mountain Institute (ref), promotes the hydrogen economy as the future, and hydrogen as a future energy source is not controversial if one assumes abundance of fuel feedstocks and distribution of energy production. Solar hydrogen can be produced anywhere, and wind hydrogen can be produced in most places around the world. We do not put such a high stake into batteries or supercapacitors when it comes to energy for cars, simply because chemical fuels are up to 140 times as energy dense. A typical energy density chart typically has chemical fuels off-the-charts good:&lt;br /&gt;
&lt;br /&gt;
Fig. Show specific energy density of storage media, with bats and caps, and chemical fuels, for perspective - https://en.wikipedia.org/wiki/Supercapacitor#/media/File:Supercapacitors-vs-batteries-chart.png. With supercapacitors having 100x less energy storage per weight than Lithium-Ion batteries, while costing 10x as much as ($2.85/kJ) as those batteries ($0.8/kJ), they are super-completely out of the question with today’s technology except for niche applications. Engines are .5kW/kg https://en.wikipedia.org/wiki/Power-to-weight_ratio#Engines  and Fuel (gas, diesel, methane) is 50MJ/kg and hydrogen is 140MJ/kg - or 50-140x more energy per weight than batteries. Given the environmental challenges of mining and recycling scarce metals, there is little case for battery-powered cars.&lt;br /&gt;
&lt;br /&gt;
That means that a non-battery car can lug around a higher percentage of payload (persons, cargo) rather than carrying around more car structure and batteries. &lt;br /&gt;
&lt;br /&gt;
For other purposes, biofuel pellets are desirable for heating fuel (after energy efficiency and solar thermal is maxed out) - such as by an aquaponic greenhouse with a black tubing heat exchanger.&lt;br /&gt;
&lt;br /&gt;
Biofuel pellets can be burned partly to release heat in winter - and if taken out of combustion after the volatile chemicals are burned off but before carbon burns to ash - then we have produced charcoal that can be used in a combustion engine. Thus, dual-fuel hydrogen/charcoal cars are in our view the transportation of the future. We are open to fuel cells entering the scene, and at $134/kW they are almost feasible.https://energy.gov/eere/fuelcells/fuel-cell-technologies-office-accomplishments-and-progress  They are too complex at this point for easy DIY production, so we may revisit this in 10 years if the technology becomes more accessible. Currently, fuel cells require exotic plastics and platinum, both of which are scarce resources. We are aiming for a sub $10k car which can be made with a standard internal combustion engine (ICE) running on hydrogen. Did you know that the first internal combustion automobile in the world ran on hydrogen in 1808? https://en.wikipedia.org/wiki/Fran%C3%A7ois_Isaac_de_Rivaz  Furthermore, ICEs are about 20% efficient - ICEs running on hydrogen are about 40% efficient. For comparison,  fuel cell vehicles are 50% efficient.http://environment.yale.edu/gillingham/hydrogenICE.pdf  Given that the efficiency gain of 25% of fuel cells over hydrogen ICEs comes at a 10x larger cost today, the case for pursuing hydrogen ICEs is much higher than the case for fuel cells. much cheaper H2ICE are seen by many experts as the means to provide a transition between emitting and non emitting transport and stationary system. https://pureenergycentre.com/hydrogen-engine/ &lt;br /&gt;
&lt;br /&gt;
Fig. The possible cost of a fuel cell car today for a 200kW sedan is $26k - and an overall minimum of about $75k. The open source hydrogen microcar is aimed at an under $10k cost and more than 100 mpg using widely available technology. (comparison of components and price, using ref 3 above)&lt;br /&gt;
&lt;br /&gt;
The answer already under our nose that is perhaps the most optimistic case for the energy revolution is solar power - at 0.015 cent per kilowatt-hour - demonstrated in 2016 by the Seed Eco-Home. http://opensourceecology.org/wiki/Hydrogen_Production  This is 4x cheaper than gas turbine electric generation  https://qz.com/135032/fuelcell-energy-fuel-cell-profit/  , and it allows for an equivalent 80 cent per gallon electricity cost for producing hydrogen.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
==The Power Cube==&lt;br /&gt;
&lt;br /&gt;
Our current Power Cube is a universal power unit that can power any of the large GVCS  machines, from cars to lathes to the brick press. The Power Cube is gasoline powered and has a 16 hp engine. We already ran this on charcoal gas - and as such - the same power cube can readily be used in dual-fuel operation - gasoline on the one hand, and charcoal on the other. Once we add the gas production infrastructure - the power cube can run on the hydrogen and biogas production from the House.  Because the pelletizer is part of the GVCS - we can make charcoal pellets from biomass pellets as a byproduct of space heating.  The concept of pellets is important - in that pellets are a flowable fuel. Meaning - that just like gasoline or tradition fuels - it can be stored in a tank and delivered as fuel as if it were a liquid - by using a small auger. This makes pellets a convenient fuel source, which unlike wood - can be used automatically in small machines.&lt;br /&gt;
&lt;br /&gt;
Moreover, the Power Cube can be run on solar energy, allowing for autonomous tractors and solar cars to enter. Solar power cubes are a good idea for shop power - where PV on the workshop roof feeds electric power cubes for hydraulic shop power. Power cubes can also be made very small - on the 1 kilowatt scale. They can also be stacked readily for higher power, so if we want a 160 hp bulldozer, we can do that based on our existing Power Cube.&lt;br /&gt;
&lt;br /&gt;
The Power Cube involves developing open source engines so that they enter the realm of lifetime design public technology. A universal version of an open source engine means that such an engine could be maintained and produced in a distributed fashion, bringing it closer to appropriate technology with a lifecycle that includes more reusability of parts.&lt;br /&gt;
&lt;br /&gt;
Fig. The Power cube and its different fuel sources - from gasoline, to charcoal, to compressed biogas, hydrogen, and electric.&lt;br /&gt;
&lt;br /&gt;
The large torque of hydraulics makes them very flexible for driving a wide range of machines. A small power cube, such as a 300W version running on a single solar panel, can be used to drive a 2000 lb MicroTrac as a practical, autonomous tractor.  The idea is that the machine would move very slowly - all day - on solar power. This is afforded by that fact that hydraulics have high torque at any speed - making this a perfect application of solar energy to autonomous, robotic tractor drive via a small microcontroller such as a $10 Pi Zero with Wireless.https://www.adafruit.com/product/3400   Thus, we can pull chicken tractors or pig tractors with a solar robotic tractor for a diversified agriculture operation.&lt;br /&gt;
&lt;br /&gt;
Fig. Infographic. Mega power cubes for 160 hp for a bulldozer, and a micro power cube for a solar grinder/pelletizer or chicken tractor.&lt;br /&gt;
&lt;br /&gt;
Autonomous animal tractors are another possible application of Power Cubes…&lt;br /&gt;
&lt;br /&gt;
Fig. The economic breakdown of an autonomous chicken tractor. PV panel + micro power cube at $500, plus the tracked drive for another $500 with open source hydraulic motors. The hydraulic motors (SME) are produced on the open source lathe (SME).&lt;br /&gt;
&lt;br /&gt;
==The Gasifier ==&lt;br /&gt;
&lt;br /&gt;
The OSE  gasifier is a device that converts charcoal into gas for fueling engines. Note that this gasifier uses charcoal that is produced as a byproduct of space heating. The gasifier is a metal container filled with charcoal, which upon being lit via in a small burn zone with an air inlet - burns and produces gas. This gas can be used as fuel in a regular internal combustion engine. The power of this lies in that with minimal modifications, a standard engine can be fueled by charcoal - which is derived from wood or other biomass.  This means that wherever plants grow - they provide a distributed and practical fuel source byond oil wars. https://www.cnn.com/2013/03/19/opinion/iraq-war-oil-juhasz/index.html  To produce charcoal, biomass is first pelletized. Burning pellets for space heat - and removing them from the burn before they turn to ash - produces charcoal pellets.&lt;br /&gt;
&lt;br /&gt;
Fig. Infographic. Space heating produces charcoal in the OSE ecosystem.  The Gasifier vaporizes charcoal, which is then burned in a standard engine. This process can be used to fuel cars - no engine modification required.&lt;br /&gt;
&lt;br /&gt;
The first reaction may be that if we turned plants into vehicle fuel - then we would destroy all of nature. That is not true, because there is plenty of biomass reserve that can be used to fuel the entire American car fleet, which uses about 60% http://needtoknow.nas.edu/energy/energy-use/transportation/  of all the energy in the transportation sector. Did you know that the largest single crop in the United States is lawn? There are 40 million acres of turf grass. http://scienceline.org/2011/07/lawns-vs-crops-in-the-continental-u-s/  What if we turned lawns into fuel crop, while increasing esthetics and reducing herbicides? Yields of grass are 4 dry tons per acre https://en.wikipedia.org/wiki/Biomass  - and if charcoal is produced at 25% efficiency - that is one ton of charcoal per acre - or 40 million tons of charcoal can be harvested from lawns alone, with no effect on food production, while increasing the ecological diversity of lawns. The average american uses 500 gallons per year of fuel.  https://www.treehugger.com/culture/pop-quiz-how-much-more-gas-do-americans-use.html  Lawns could thus provide ¼ of the entire car fleet fuel in the USA! (Charcoal is ¾ the energy content of gasoline by weight. At about 3 kg/gallon - 500 gallons is 1500 kg- about 1.5 metric tons - so 33M people could be supplied by fuel from lawns. If 95% of households have cars - https://photos.state.gov/libraries/cambodia/30486/Publications/everyone_in_america_own_a_car.pdf - and household is 2.6 - there are about 120M drivers in the USA. Thus  - ¼ of US drivers can be fueled by lawns.) This is at the crappy USA 23 miles per gallon - so increasing fuel efficiency to 100 mpg https://www.motherearthnews.com/green-transportation/green-vehicles/build-your-own-car-zm0z13amzmar with super-efficient micro-cars could mean that the entire US car fleet is supplied by fuel from grass. Efficiency and ecology - as opposed to battery technology with questionable environmental side effects and its centralization based on scarce resources - make the OSE platform converge on biomass and hydrogen as the fuels of choice. The OSE platform reserves the role of batteries only as a small part of vehicular power, not the backbone of the auto industry. &lt;br /&gt;
&lt;br /&gt;
The biomass route needs no technical invention to realize - today - and is also a carbon-neutral route. From the OSE perspective - hydrogen is clean (it produces water as the byproduct) but not better on ecological grounds (it does not contribute to biological ecology) - but it is much better on efficiency grounds.&lt;br /&gt;
&lt;br /&gt;
When discussing biofuels, it is important to point to the food-fuel-fiber integrated agroecology route as the preferred OSE route to agriculture. As opposed to genetic engineering to produce super-crops, the OSE platform favors ecological integration over genetic manipulation - so that we avoid creating super-problems at the same time. The ecological route means that we learn more about dealing with integrated ecosystems, not trying point solutions (genetic engineering) as a cure. When dealing with powerful technologies like genetic engineering, we must pay attention to unintended consequences. The current economic paradigm of profit maximization is not compatible with care in the use of genetic engineering. We favor increasing productivity by stacking yields of multiple crops that work harmoniously in a polyculture setting - with tree crops as a significant component. For us, the breakthrough work of Badgersett Research Farm is seminal in providing this leadership. They are developing perennial crops (hazelnuts and chestnuts) that could serve as a viable replacement for soybeans and corn. (ref).  Hazelnuts and chestnuts provide the same nutrition as their annual counterparts - but are perennial - and therefore do not contribute to the average 4 ton per acre annual soil erosion in the United States. (ref). Let me repeat that - the avarage topsoil loss in the United States - per acre - is 4 tons. What that means is that agricultural soils today are so depleted that they could not grow crops if it were not for the heavy inputs of fertilizers. The biological activity of commercial farmland is severely depleted (ref), not sustaining the soil food web of microbes that bring fertility back to the soil. (ref). Our proposition for perennial polyculture - is not new (ref on seminal works, Tree Crops, Regrarians, etc) - and it can produce food, fuel, and other materials.&lt;br /&gt;
&lt;br /&gt;
To improve the world, all you need to do is plant trees. Desertification still claims an additional ______________ square miles every year, and it would be good to reverse that.&lt;br /&gt;
&lt;br /&gt;
It takes less than 60x the land area to produce solar hydrogen compared to the land area required to grow biofuel crops.  Between biofuel (easy) and hydrogen (hard), humanity’s fuel needs can be met. Let’s look at numbers: we already said 300 gallons of fuel equivalent per acre (enough to fuel one car for a year at a fuel economy of 40 MPG https://www.google.com/search?q=average+miles+per+year+usa&amp;amp;oq=average+miles+per+year+usa&amp;amp;aqs=chrome..69i57j0l2.7415j0j7&amp;amp;client=ubuntu&amp;amp;sourceid=chrome&amp;amp;ie=UTF-8 ) fuel consumption -  roughly one gallon per day. If we apply this to hydrogen - 50kWhr of electricity is required to produce 1 kg of hydrogen, roughly one gallon gas equivalent. This can be obtained from a 9 kW PV array - running 6 hours per day - 54kWhr. The space required for a 9 kW array is 60 square meters if the panels are 15% efficient. An acre is 4000 square meters - so producing solar hydrogen requires 66 times less land area than growing the equivalent grass. Our materials cost for 9 kW of solar panels is under $9k. So one can obtain 20 years of hydrogen fuel for a PV investement cost of $17k.&lt;br /&gt;
&lt;br /&gt;
Fig. Home hydrogen production. The OSE open source goal is $9k for PV panels, $2k for storage, $2k for pump, $2k for plumbing, and $2k for the electrolyzer. That is $17k for a lifetime supply of hydrogen. Compare to gasoline - $1250/year on average. Payback time for  home fuel station is 14 years in the USA and 7 years in Europe. We intend to make hydrogen production a standard feature of the Seed Eco-Home.&lt;br /&gt;
&lt;br /&gt;
Add a paragraph about renewable energy plantations - perennial polycultures for fuel, food, fiber. &lt;br /&gt;
&lt;br /&gt;
Fig. Basic economic model for renewable energy plantations involves $x/acre in coppiced fuel, $1000/acre in nuts, and $2k/acre in sustainable chickens that fertilize the crop via autonomous chicken tractors.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
==Heat Exchanger==&lt;br /&gt;
&lt;br /&gt;
The heat exchanger is a device that takes heat from one medium and puts it into another. For example, in the Seed Eco-Home - we have a hydronic stove with heat exchanger which is used to heat water for heating the house.&lt;br /&gt;
&lt;br /&gt;
Fig. Hydronic stove with heat exchanger. A heat exchanger heats water, and if that water is boiled, it can be used to run a steam engine or turbine. Small steam engines have been used for shop power 100 years ago, and they can be used even more effectively today. You can get a working kit for $275 on Ebay.&lt;br /&gt;
&lt;br /&gt;
Simpler examples of the heat exchanger are the Hillbilly Heater. This device traps solar heat and puts it into water circulating through the black tubing. This energy is released through another coil in the aquaponic ponds, for example. A closed heat exchanger means that the water in the black tubing does not mix with the pond water. Or, this heat exchanger could be an open heat exchanger, where the water is heated and then used as hot water in a shower - so that a steady supply of new water is fed through the exchanger instead of just circulating - as in the pond heating case.&lt;br /&gt;
&lt;br /&gt;
Fig. The hillbilly heater can be used to heat ponds or to provide hot water for the house.&lt;br /&gt;
&lt;br /&gt;
==Modern Steam Engine==&lt;br /&gt;
&lt;br /&gt;
The modern steam engine is an engine that produces power from steam. The industrial economy was created by steam power. And steam turbines are the main way that power is generated today. &lt;br /&gt;
&lt;br /&gt;
A modern steam engine is a small engine that makes sense to build wherever space heating is involved. For example, a centrally heated building could be generating power at the same time as its being heated - if a heat engine with a generator is added to the system. Thus, we are piggy-backing on an existing power source, while using all the waste heat.&lt;br /&gt;
&lt;br /&gt;
Under 500 hp - or in any small scale installation - it is more effective to have a steam engine as the engine of choice. Above 500hp, it is more effective to use a steam turbine. Large power plant steam turbines reach 50% efficiency. https://en.wikipedia.org/wiki/Steam_turbine#Practical_turbine_efficiency &lt;br /&gt;
&lt;br /&gt;
A flame-fired or solar-powered heat exchanger can produce steam - for electricity generation. This makes sense for combined-heat-and-power systems. Most of today’s electricity is produced by water that is boiled in power plants to provide electricity via steam turbines. (ref) This can be done effectively on a scale of 500 or more horsepower - which is village scale, not home scale. For the smaller scale, a small steam engine can be used. For this reason, we have incorporated a modern steam engine into the GVCS - as a machine for producing electricity on top of a heat source. This could be done in our hydronic stove - where the water goes from the steam engine and then to house heating after some power has been extracted for electricity. It makes sense to convert the heat into high grade electricity - when the steam engine is connected to a generator.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
Did you know that the modern steam engine - a specific advanced version -  is more efficient than the internal combustion engine? The Cyclone engine is a high tech, high temperature steam engine made of stainless steel and exotic materials - with thermal efficiency over 30%. http://cyclonepower.com/ &lt;br /&gt;
&lt;br /&gt;
There is another steam engine that received a lot of attention on the internet but appears not to work well - the Green Steam Engine. We do not endorse the engine, as suggested by Tom Kimmel of Kimmel Steam Power  http://kimmelsteam.com/green-robertengine.html  - and you can read more in an old blog post. (http://opensourceecology.org/steam-meet-report/ . I have since contacted Mr. Greene for data on Feb 1, 2018, but I have not been presented with any data.)&lt;br /&gt;
&lt;br /&gt;
All together, the modern steam engine is valuable for household power, if the Power Cube is used for mobile power. Would would be the cost of a steam engine add-on to a household infrastructure? Small models of ¼ hp are available for under $300 in parts, (http://ebay.to/2EwmHWt ) and these are scalable readily to larger sizes. The current seed eco-home stove has sufficient power to run this engine, so only an additional pump would be required to feed water to this system.&lt;br /&gt;
&lt;br /&gt;
Integration of such a system would work well if pelletized biomass were used as fuel - and subsequently - charcoal would be produced for use in cars as a byproduct of household power generation. An interesting milestone would be an automated biomass energy system from an autonomous tractor-pelletizer - up to the production of charcoal as car fuel using gasifiers - all from one’s former lawn converted to bioenergy crop.  In such case, nickel iron batteries may be desirable in so far as excess energy storage from daytime solar power.&lt;br /&gt;
&lt;br /&gt;
Fig. The energy product ecology of the Seed Eco-Home includes solar hydrogen, biogas for cooking, and production of car fuel from the lawn.&lt;br /&gt;
&lt;br /&gt;
==Solar Concentrator==&lt;br /&gt;
&lt;br /&gt;
The modern steam engine equation becomes much more exciting when solar concentration is used. Using 30% efficient, modern steam engines, proven linear solar concentrators, and a night-time storage system based on large, insulated propane tanks with hot water - it is possible to produce an off-grid energy system with $100/kWhr energy storage costs - 4x cheaper than lithium ion batteries. https://en.wikipedia.org/wiki/Lithium-ion_battery  A breakthrough company - Terrajoule - has already demonstrated this. Then the question becomes - if this has already been shown in the first prototype of Terrajoule, why isn’t everyone doing this when the technology is all proven? One cannot beat the simplicity of water and solar heat as the ultimate storage medium. &lt;br /&gt;
&lt;br /&gt;
What can water really do? When water is heated but not allowed to expand, it turns to what is known as saturated water. A saturated liquid is a liquid whose temperature and pressure are such that any decrease in pressure without change in temperature causes it to boil. In other words, if a tank was not holding the water at pressure - that water would turn into steam.&lt;br /&gt;
&lt;br /&gt;
Just how much energy can that water store at a medium pressure? A lot. Looking at the total heat content of water that would otherwise turn to steam, but is held under pressure at 18 atmospheres (250 PSI) in a tank instead http://opensourceecology.org/wiki/Saturated_Water  - we see that each kilogram of such saturated water holds about ¼ kWhr of energy. That means that a 10,000 gallon propane tank can store about 4MWhr of energy! We can extract that energy with a modern steam engine, where steam engines from the 1950s got to about 30% efficiency. https://en.wikipedia.org/wiki/Uniflow_steam_engine   After all the losses, we we would have 300kWhrs of electricity when the modern steam engine runs a generator.&lt;br /&gt;
&lt;br /&gt;
We can scale that down to a residential system - just a 1000 gallon propane tank - and 30kWhrs of electricity produced.&lt;br /&gt;
&lt;br /&gt;
Fig. Cost and energy of a home-scale solar energy storage system using water and modern steam power. From energy content of 400kWhrs to 30kW hours of electricity is quite doable using proven technologies, at ¼ the cost of battery storage.&lt;br /&gt;
&lt;br /&gt;
==Nickel Iron Battery==&lt;br /&gt;
&lt;br /&gt;
Nickel-Iron Batteries are long-life batteries that have a track record of lasting 50 or more years. Unlike other batteries, these can be discharged fully without decreasing their lifetime. These are chosen for the Global Village Construction Set specifically for their long life - and becuase nickel and iron are not scarce resources. While heavier and 2x more expensive than lithium ion batteries, (Read an intereresting pro-con discussion - http://opensourceecology.org/wiki/Nickel_Iron_vs_Lithium_Ion_Battery_from_Tesla_Motors ) they make up by their long lifetime, and lend themselves to decentralized production. New developments are in progress, ( https://news.stanford.edu/news/2012/june/ultrafast-edison-battery-062612.html )  though OSE does not rely on new developments for feasibility given that OSE internalizes social and environmental aspects for true cost accounting. The cost is currently high because production volume is low - only 2 US manufacturers. Based on a nickel price of $6/lb and iron at 25 cents/lb, and a weight of 100 lb for 1kWhr - and a 20% content of nickel in nickel iron batteries https://www.solarpaneltalk.com/forum/off-grid-solar/batteries-energy-storage/ni/7052-how-much-nickel-is-really-in-a-ni ckel-iron-ni-fe-battery - the base materials cost of materials in Nickel Iron batteries appears to be $150/kWhr. That is similar to lead acid batteries and ½ of lithium ion costs - but if the lifetime of these batteries is really 50 years, then they are 5-10x cheaper than other batteries based on lifetime.&lt;br /&gt;
&lt;br /&gt;
According to recent research: https://link.springer.com/content/pdf/10.1007/s10800-015-0911-3.pdf &lt;br /&gt;
&lt;br /&gt;
There are many reasons favouring the use of NiFe cells as cost-effective solutions to store grid-scale amounts of energy, such as low cost of raw materials, environmental friendliness, electrical abuse tolerance, long life (in the order of thousands cycles of charge and discharge) and compatibility with photovoltaics (PVs). Due to the nature of the heavy metals involved in its construction this technology is suitable for stationary low gravimetric energy applications (30–50 Wh kg-1 ). As a consequence, there are good reasons to foresee a large scale utilization of this technology. Due to their outstanding safety properties (zero flammability, fail safe, no over/ under charge), low cost and long lifetime, we anticipate that they will receive widespread public acceptance for customer-connected energy storage.&lt;br /&gt;
&lt;br /&gt;
It is our hope that the nickel iron battery would be only a small fraction of electrical power storage needs in the future - such as replacing 5-year lifetime starter batteries in vehicles. For night time electricity, it would be useful for warmer regions to use solar concentrator saturated water storage - as one possibility - or solar hydrogen as another.&lt;br /&gt;
&lt;br /&gt;
In colder areas, biomass is typically available as an abundant energy crop - where PV may not be adequate if there are weeks without sun. The exact mix of solar concentrator electric, PV, wind, charcoal, biomass, biogas, and hydrogen is to be determined at Factor e Farm as we measure the value of all these systems side by side. The main requirement for OSE is true service to humanity, environmental regeneration, and freedom from resource conflicts.&lt;br /&gt;
&lt;br /&gt;
==50 kW Wind Turbine==&lt;br /&gt;
&lt;br /&gt;
A wind turbine converts a renewable form of energy - wind - into electricity. It provides a good backup to PV electricity, as wind typically blows when the sun is not out.&lt;br /&gt;
&lt;br /&gt;
We propose a vertical axis wind turbine for the initial OSE version based on integration with hydraulics and the Universal Rotor.  A simple system can consist of a pole mounted 40 hp hydraulic motor ($400), serving as a pump - which transfers fluid power to an on-the-ground hydraulic motor ($300) + 24 kW generator ($1000). The power generator related costs are ~ $2000 here, and the rest is the tower and structure. With $6k spent on the materials for this wind turbine, this would be $250/installed kW in materials costs - with installation being 15% on top of this http://www.esru.strath.ac.uk/EandE/Web_sites/14-15/XL_Monopiles/cost.html  - a very attractive package in a sweet spot of cost for readily-available components. This is compared to $1590/kW standard costs of large scale wind installations. https://www.awea.org/falling-wind-energy-costs &lt;br /&gt;
&lt;br /&gt;
The OSE design features a generator that is mounted on the ground, with only the hydraulic motor on top of the tower. This facilitates maintenance considerably. The savings is due in part to the great simplification of the nacelle - in the OSE case, the vertical axis design doesn’t have a yaw mechanism - it’s just a hydraulic motor that accepts wind from any direction. These turbines are not as efficient in terms of wind capture as they are lower to the ground - but the low capital + maintenance costs make up for the lower efficiency. Because they can be packed more tightly in the same area, however - VAWT wind farms can actually produce 10x the energy of a propeller-type wind farm. https://en.wikipedia.org/wiki/Vertical_axis_wind_turbine#Advantages  They also self-regulate their speed, so they do not need a braking meachanism for overwind conditions.&lt;br /&gt;
&lt;br /&gt;
Fig. OSE VAWT concept. Simplification of design include ground-mounted generator, yawless rotor, screw pile foundation https://en.wikipedia.org/wiki/Screw_piles#Modern_Use_and_Benefits  , and braking via the hydraulic motor as the overspeed protection. The wind turbine module is designed for 24 kW, and it includes the Electric Motor/generator, Universal Rotor, Hydraulic Motor, Power Cube, and Universal Power Supply for managing power.&lt;br /&gt;
&lt;br /&gt;
8. Universal Power Supply&lt;br /&gt;
The Universal Power Supply (UPS) is the last of the energy machines. It is a universal device for powering large electronic machines - induction furnaces, welders, plasma cutters, laser cutters - and for controlling power delivery and transmission to homes or electric cars. It is also used for charging. The UPS has feedback such that it would know when batteries are full, or for optimizing the power transfer into a load of metal that is melted with the induction furnace. &lt;br /&gt;
&lt;br /&gt;
The Universal Power Supply in general  converts AC and DC into voltages and currents of any amplitude and frequency. The UPS is scalable from a few watts to 20kW based on the same design of modules.  The Universal Power Supply can also be used to condition power from the wind turbine or PV system and pump it into the grid. It can also be used as an inverter to convert DC to AC, or it can be used to control the speed of an electric car. It can also be used to step power up to high voltage for power transmission over longer distances, such as up to the 69,000 volts for rural power lines. &lt;br /&gt;
&lt;br /&gt;
As with the mechanical machines, the Universal Power Supply is based on modular design, such that we can arrive at a Construction Set. Just like power units, wheels, shafts, hydraulic motors, control valves, and frames can create any mechanical industrial machine, so can a small number of modules provide just about any electrical power function in the Universal Power Supply. These modules are mainly: a microcontroller, a current measurement device, a transistor, wires, laminated cores, ferrite beads,  diodes, optocouplers, resistors, capacitors, and inductors - plus a few mechanical components such as plugs, cases, cooling systems. With advanced transistors that now cost $1 per kW of power handling, large power electronic devices can be built on the cheap if open source knowhow is available.&lt;br /&gt;
&lt;br /&gt;
Wires and metal cores themselves produce a wide range of devices: inductors, transformers, relays, solenoids, switches for large currents, electric motors, spark generators, electromagnets, and other devices. &lt;br /&gt;
&lt;br /&gt;
Lasers, charge controllers, inverters, welders, induction furnaces, plasma cutters, oxyhydrogen generator power supply, and motor controllers are all functions that can be generated with the Universal Power Supply. These are all based upon currents and voltages at different frequencies and amplitudes that perform radically different functions. This has to do with the nature of electricity - jus like a few atom types (100 or so) make up millions of different substances that are all around us - so can electricity be manipulated to perform a wide array of functions. Any of the above devices consist of a microcontroller and a power transistor - along with some resistors, capacitors, and inductors. The microcontroller could be an Ardduino or a Rasperry Pi - which now cost as little as $5 for these small computers running with a 700MHz cpu. This CPU - via software - can produce a voltage of any amplitude and frequency using transistors. In other words - a ‘brain’ - the CPU - can massage electrons so they maifest at any voltage or frequency - by using transistors - or devices where a small signal from a CPU controls a large voltage. Essentially - a transistor is a switch - which is activated by a small signal.&lt;br /&gt;
&lt;br /&gt;
For example - taking DC voltage - one can make it pulsed and appear as an oscillating sine wave. This is an inverter for household power - which can for example take electricity from PV cells and convert that into household current. Or - this same inverter can be pulsed much faster to create a 30kHz voltage used in an induction furnace. And regulation can happen - such as an induction furnace delivering power most effectively to the molten charge - when the same microcontroller can measure the voltage, and change the frequency of the applied voltage to pump power more effectively into the melt. &lt;br /&gt;
&lt;br /&gt;
This is all possible because superfast microcontrollers, and high power handling transistors - can all be purchased now for a few dollars.&lt;br /&gt;
&lt;br /&gt;
Energy Summary&lt;br /&gt;
&lt;br /&gt;
Combining biomass, charcoal, biogas, wind power, the solar concentrator,  steam electricity, hydrogen, PV - and the electronic controls of the Universal Power Supply -  makes for a resilient power infrastructure without necessitating resource conflicts.&lt;br /&gt;
&lt;br /&gt;
=Open Source Microfactory=&lt;br /&gt;
&lt;br /&gt;
The Open Source Microfactory (OSM) is the crown jewel of the Global Village Construction. It is the part that allows for GVCS self-replication - in that the Open Source Microfactory allows for the production of all the  GVCS tools - including the Microfactory itself..&lt;br /&gt;
&lt;br /&gt;
The Open Source Microfactory is broken into 2 main parts: precision CNC tools, and metal production tools. The CNC tools - which stands for Computer Numerical Control - are automated machines that can be programmed to build things - from small parts, to engines, and everything in between. The metal production tools allow for the production of virgin steels from scrap. The steel that can be produced with the GVCS metal tools thus allows for the creation of advanced civilization - wherever there is access to scrap steel. Scrap steel is abundant, and so it iron ore from which steel is made. Iron is the 4th most abundant element in the earth’s crust - after oxygen, silicon, and aluminum. https://en.wikipedia.org/wiki/Abundance_of_elements_in_Earth%27s_crust &lt;br /&gt;
&lt;br /&gt;
What if there is no scrap steel available? We can go to aluminum - which is even more abundant in terms of the crust’s composition. Aluminum is found in common clay. Clay is aluminosilicate, from which aluminum can be extracted. Because Aluminum is so abundant - the GVCS goes so far as the extraction of aluminum from clay. This is intended to break through any notions of scarcity in today’s civilization.  Clay is abundant, and it’s an essential part of the GVCS: compressed earth blocks, soil for growing food, clay for 3D printed pots and cookware - in addition to the production of aluminum metal.  &lt;br /&gt;
&lt;br /&gt;
Fortunately - silicon is even more abundant. We get solar cells for producing electricity from silicon - a core technology for the GVCS such as in the Seed Eco-Home. In less than the time it takes to read this paragraph, the sun will have provided as much energy to Earth as used by all of human civilisation in one day. Thus silicon solar cells are important. And silicon is used to make semiconductors - so silicon creates the computer age.&lt;br /&gt;
&lt;br /&gt;
With the Open Source Microfactory - we thus aim to show that literally, modern civilization may be created -  from dirt and twigs. This can happen on any parcel of land - as solar cells can easily produce about 500kW of energy - from an acre. So a facility such as the OSE headquarters can produce all the technology required to produce an advanced civilization. For example, 500kW of solar energy - or 3MWhrs per 6 hours of daylight - can produce 200 kg of aluminum per day. Aluminum requires 15 kWhr per kilogram to smelt. (http://wordpress.mrreid.org/2011/07/15/electricity-consumption-in-the-production-of-aluminium/ . This one says ,05 GJ/kg - http://wordpress.mrreid.org/2011/07/15/electricity-consumption-in-the-production-of-aluminium/ )Aluminum is energy intensive - but its production may one day be improved for more environmentally-sound production - as can any other process by internalizing environmental costs.  https://www.sciencedirect.com/science/article/pii/S0360544207001065#! &lt;br /&gt;
&lt;br /&gt;
This shows how energy intensive aluminum production is - but its 3x better weight to strength ratio compared to steel makes it a desirable product. With the proposes 200kW solar microfactory - we can produce 80 kg of aluminum per day. That’s not a lot - but acceptable as a proof of concept for an appliance-size machine.&lt;br /&gt;
&lt;br /&gt;
Aluminium is the most abundant metallic element in the Earth’s crust (about 8%) and the&lt;br /&gt;
second most widely used metal next to steel. The aluminum production process involves taking ordinary clays such as abundant kaolin clay - and leaching out alumina with hydrochloric acid to produce Al203, which is subsequently turned to Aluminum via electrolysis at a cost of 15 kWhr per kg of aluminum produced. For reference in terms of energy requirements - this is like converting one gallon of gasoline to one kg of aluminum. That’s a lot of energy. But the main point here is that this can be done anywhere where there is soil - clay for making aluminum is an abundant feedstock.&lt;br /&gt;
&lt;br /&gt;
If we talk about the carbon dioxide emissions - whether from aluminum or steel production - the way we propose to make it sustainable is to make the CO2 recyclable. If the carbon involved in the reactions for producing metals - or for that matter any other product - comes from charcoal derived from biomass - then the industrial process is regenerative as the plants that were used to produce the charcoal took the carbon out of the atmosphere in the first place. Thus, a sustainable industry is possible  when civilization evolves to using charcoal  instead of fossil fuels. &lt;br /&gt;
&lt;br /&gt;
However, it should be stated that CO2 in the long run may be more advantageous for ecology - even from fossil fuels - if that CO2 yields more plant growth. While many people see CO2 per say as a global warming problem - it is also possible that the CO2 will make the earth more green. Nobody knows what will happen at this point - we can only speculate as to the long term effects of increasing CO2 in the atmosphere. &lt;br /&gt;
&lt;br /&gt;
The open source microfactory is intended to produce an entire technosphere from local resources, pushing the limits of what can be done:&lt;br /&gt;
&lt;br /&gt;
Fig. Open Source Microfactory cyclic material flows can be based on local resources. Metals, bioplastics, ceramics, PV cells, concrete, carbon, hydrogen, glass, rubber, fuels, food, construction materials, and many other chemicals can be produced from local abundance.&lt;br /&gt;
&lt;br /&gt;
If it is indeed that PV cells can be made from local sand, and aluminum from clay - and everything else as noted - then we have truly stepped into a world of post-scarcity. At the point where material production is guaranteed, it may be possible for people to evolve full time - without being held back by mere survival. That is the essence of society that OSE intends to create - one in which material needs are not in the way of human evolution.&lt;br /&gt;
&lt;br /&gt;
For any other processes of industry - the Open Source Microfactory can provide. If you can make buildings, glass, metal, and plastics + other materials - you can build anything. Advanced processes such as chemical plants or semiconductor fabs - are nothing but buildings, metal vessels, motors, vacuum pumps, and a few other basics - and from there spews out any product - in a nutshell. This does not even involve the nanotech of molecular manipulation - where it is deemed that in the future we will be able to synthesize substances by moving atoms directly - without regard for chemical reactivity as we know it today. Yet we do not invoke the Technological Singularity as a prerequisite for meeting all human needs.&lt;br /&gt;
&lt;br /&gt;
Let’s move to the specific tools in the Open Source Microfactory:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
And &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Fig. Tools of the Open Source Microfactory. They include everything needed to produce precision metal parts starting from scrap metals, glass, bioplastics, and even semiconductors for solar cells. &lt;br /&gt;
&lt;br /&gt;
==Universal Axis==&lt;br /&gt;
&lt;br /&gt;
Six of the Open Source Microfactory tools are based on the Universal Axis. The Universal Axis is a modular, and scalable CNC axis which can be used to create cartesian CNC machines. The core of the axis design is belt drive and linear motion rods where carriages are pulled on the rods. The system is scalable to any size and number of axes, including rotary axes. The system uses a combination of 3D printed parts, metal plates, and belt-driven shafts. Applications include 3D printers, CNC torch tables, heavy duty CNC machines, and many other production machines.&lt;br /&gt;
&lt;br /&gt;
We intend to use the 5/16”, 1”, and 2” versions for 3D printers, CNC torch tables, and heavy duty CNC machines - which are among the key machines that can be built with the system - though a variant of any size and shape can be designed.&lt;br /&gt;
&lt;br /&gt;
Fig. The universal axis comes in 5/16”, 1”, and 2” variations, and is based on belt drive, though a screw and nut system can also be used as a drive. Various tool heads can be attached. Non-contact tool heads are attached magnetically, such as the laser cutter and 3D printer. Rotary attachments can even be used for 3D scanning or indexing.&lt;br /&gt;
&lt;br /&gt;
For heavy duty applications, the plastic plates may be reinforced with steel plates - making a steel-plastic composite that has the required strength - while being easy to produce because the complex geometry is 3D printed. The metal plates themselves can be CNC cut using the CNC torch table. This allows for the lowest cost route - the 2” bushings capable of 8000 lb force on these axes currently cost only $9.41 at McMaster Carr.&lt;br /&gt;
&lt;br /&gt;
Fig. Metal-plastic Universal Axis System.&lt;br /&gt;
&lt;br /&gt;
The power of the universal axis lies in its flexibility. The same design of the drive system can be used to make an unlimited range of fabrication machines, putting the manufacturing process completely in the hands of anyone - without high barriers to entry. This is aimed at the Open Source Microfactory in every town, where our goal is to distribute at least 10,000 of these open source microfactories around the world, each generating at least $100,000 of net revenue per year. Once production returns to communities, we expect that taxes will go down as communities once again become responsible for their own prosperity.&lt;br /&gt;
&lt;br /&gt;
==The 3D Printer, Bioplastic Extruder, 3D Scanner==&lt;br /&gt;
&lt;br /&gt;
The 3D printer is a machine with diverse applications. Essentially, the technosphere is made from plastics, ceramics, and metals. 3D printers can print with all of these, and are as such ubiquitously applicable to manufacturing of all sorts. Currently, it is easy to print with all kind of plastic, including rubber for printing tires and polycarbonate for printing glazing. It is likewise easy to print ceramics - by printing clay and then baking it. Here we can produce ceramic cookware or clay parts such as insulators or building bricks. If the clay contains a large fraction of glass or metal - then upon kilning - 3D printed glass and metal objects can be printed as well. Metal printing can also happen via a MIG or TIG welder as the working toolhead - where large metal structures can be printed additively like this. If we go a step up to lasers - we can do selective laser sintering of any kind of powder - from plastic, to ceramic, to metal. Extremely strong, precise metal parts can be created this way - such that for example the rocket engine for Elon Musks’s SpaceX rockets has been 3D printed.&lt;br /&gt;
&lt;br /&gt;
Fig. Different applications of 3D printing: plastic, rubber, glass, metal, ceramic, and housing.&lt;br /&gt;
&lt;br /&gt;
Carbon fiber or metal fibers can also be embedded in plastic 3D prints to make the parts as strong as aluminum. 3D printing can also print ceramic molds which can then be used for casting directly into these molds - using either molten metal from an induction furnace or a MIG weld right into the metal form.&lt;br /&gt;
&lt;br /&gt;
Fig. Apparatus for automated metal casting using 3D printing of molds + induction heating of melt to fill the molds.&lt;br /&gt;
&lt;br /&gt;
Currently - open source printing includes  plastic + rubber 3D printing, welder 3D printing, clay printing for ceramics, clay-metal 3D printing for metals, selective laser sintering of plastics, and 3D priting of concrete or clay buildings. With a little bit of work,  the full printing with metal or glass using selective laser sintering can be developed by using off-the-shelf technologies. An 80W laser tube like in the Laser Cutter + shielding gas allows for selective laser sintering of off-shelf metal powders. http://opensourceecology.org/wiki/Metal_Selective_Layer_Sintering#Literature &lt;br /&gt;
&lt;br /&gt;
Fig. If metal powder is available (it is, such as iron at $1/lb) - then we can use a laser to fuse a powder bed to complex 3D objcts that cannot be produced in any other way.&lt;br /&gt;
&lt;br /&gt;
The world of 3D printing is in its infancy - and this is definitely worth refining to achieve full 3D printability in any material. Perfecting all of the above 3D printing can go far towards local production of just about anything.&lt;br /&gt;
&lt;br /&gt;
==Bioplastic Extruder==&lt;br /&gt;
&lt;br /&gt;
The Bioplastic Extruder is part of a system that enables the production of biodegradeable bioplastics from natural feedstocks such as cellulose or sugars. The system includes 3D printing filament production as well as direct extrusion of useful parts.  &lt;br /&gt;
&lt;br /&gt;
Four main aspects are involved in the Bioplastic Extruder System. First, a bioplastic reactor is used to make bioplastic from abundant biological feedstocks such as cellulose, sugar, or starch. Second - once the plastic is produced - or is available from the waste stream - it can be extruded with the Bioplastic Extruder to make 3D printing filament. Third, the 3D printing filament is then used directly in 3D printers to make useful objects. Fourth, other useful products can be made with the extruder: plastic lumber, which can be made from recycled plastic and sawdust. This could be a great way to recycle plastics into durable construction materials. Other useful profiles - such as tubing and glazing panels - can also be produced with the bioplastic extruder. Thus, the bioplastic extruder per se can be used for 2 main purposes: making 3D printing filament as an intermiediate feedstock for 3D printers - or extruding useful products directly.&lt;br /&gt;
&lt;br /&gt;
Fig. The bioplastic production system of the GVCS consists of bioplastic synthesis followed by extrusion to produce 3D printing filament, tubing, sheets, or plastic lumber. 3D printing filament can be used for 3D printing. Thermoplastic elastomers - or rubber - can also be printed.&lt;br /&gt;
&lt;br /&gt;
There are 3 types of bioplastics - those derived from: (1) petroleum and biodegradeable; (2) biomass and biodegradeable; and (3) biomass and non-biodegradeable. OSE is most interested in bio-based, biodegradeable bioplastics, as the feedstocks are most widely available and can be produced ecologically anywhere in the world. &lt;br /&gt;
&lt;br /&gt;
The OSE bioplastic system allows for local recycling such that the plastic never ends up in the landfill - but is either reused or recycled. By eliminating plastic waste and turning it into valuable products, wealth can be multiplied. Also, we can clean up the environment by reusing plastics - which can otherwise persist in the environment for 1000 years. Such recycling also reduces the need for petroleum - the typical feedstock of plastics.&lt;br /&gt;
&lt;br /&gt;
Bioplastics derived from biomass that are non-biodegradeable can be produced from petroleum substitutes. Petroleum can be replaced with charcoal. As such, any plastic typically derived from petroleum can also be produced from renewable, plant-derived charcoal. In the OSE system, plant matter is pelletized, then burned partially for space heating or process heat - with the byproduct being the important charcoal feedstock. If one is interested in replacing petroleum-derived chemicals - charcoal is first burned in a gasifier to produce CO and H2 - just as the gasifier fuels regular engines with CO and H2 - a combustible mixture. Instead of being burned in an engine as a renewable fuel, these molecules can combine under heat and pressure and an iron catalyst to produce long hydrocarbon chains and water. The long chains are alkanes - the typical long-chain molecules of -[CH2]- found in petroleum. This conversion process is known as Fischer-Tropsch synthesis, and is important from the abundance mindset - in that all products than now come from coal and petroleum can be made more ecologically - from plants. https://en.wikipedia.org/wiki/Fischer%E2%80%93Tropsch_process  &lt;br /&gt;
&lt;br /&gt;
Fig. The circular economy of OSE is based on wood - to make charcoal, paper, bioplastic, rubber, and fuel.&lt;br /&gt;
&lt;br /&gt;
Cellulose acetate is a bioplastic that is easily made from the most abundant organic polymer in the world - cellulose. It can be made readily from trees. Did you know that wood fibers can be converted to this bioplastic by reacting these fibers - with glacial acetic acid? The product is 3D&lt;br /&gt;
&lt;br /&gt;
printable.http://www.designforcraft.com/new-materials-for-3d-printing-cellulose-acetate/  You can make windows with it.http://nvlpubs.nist.gov/nistpubs/jres/19/jresv19n4p367_A1b.pdf  Instead of trees, one can use any source of cellulose - paper, cotton, straw, or other cellulose materials. &lt;br /&gt;
&lt;br /&gt;
Straw and wood are thus very important in the overall product ecology for making fuel pellets, insulation for the Seed Eco-Home (with borax), strawboard, charcoal, paper,  steel (charcoal with iron ore), and bioplastics.&lt;br /&gt;
&lt;br /&gt;
Polylactic Acid, or PLA, is the most popular bioplastic used in 3D printing. It can be derived from bacterial fermentation of sugar - and is thus an accessible technology within the GVCS.&lt;br /&gt;
&lt;br /&gt;
Polyhydroxyalkanoate (PHA) or polyhydroxybutyrate (PHB) bioplastic polyesters are considered the best candidates to replace the current petroleum-based plastics due to their durability in use and wide spectrum of properties. https://www.intechopen.com/books/biotechnology-of-biopolymers/conversion-of-biomass-into-bioplastics-and-their-potential-environmental-impacts  They are made by bacteria from sugar or starch at an efficiency of up to 80% of bacterial cell mass.https://www.intechopen.com/books/biotechnology-of-biopolymers/conversion-of-biomass-into-bioplastics-and-their-potential-environmental-impacts  Some PHAs are elastomers. Thus - it is realistic to include rubber production for tires - from sugar or starch - within the industrial ecology of the GVCS. Unlike latex resin from dandelion roots - which can be used to produce thermoset plastics - PHA rubber is thermoplastic, so it can be recycled easily. Both PHA rubber and dandelion root rubber can be grown anywhere - thus removing the strategic importance of tropical rubber tree plantations. It appears that PHA rubber is more viable from the decentralization perspective. Wood, broken with acid to simpler sugars - can also be used a feedstock for PHA - thus making PHA rubber production possible anywhere in the world. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4964529/   However, woody crop can compete with food crops - so we once again emphasize perennial polycultures as ways to produce food, fuel, and fiber. With perennials, it is also easier to use degraded lands, which can be regenerated back to fertility and health when annual crops are removed from the equation.&lt;br /&gt;
&lt;br /&gt;
In addition to sugar and cellulose, starch from common sources such as potatoes or corn can be polymerized readily in the kitchen. For example, mixing vinegar and glycerine with the starch makes a bioplastic.http://opensourceecology.org/wiki/Starch_Bioplastic   This is the easiest route  that can be used for 3D printing&lt;br /&gt;
&lt;br /&gt;
The bioplastic extruder has 2 main functions: one is to perform extrusions directly - or to produce intermediate 3D printer filament which is then used to 3D print final objects. For the latter, we are currently building upon two open source projects working on plastic extruders: the Lyman Filament Extruder,http://opensourceecology.org/wiki/Lyman_Filament_Extruder  and the Thunderhead Filament Extruder from Tech For Trade.http://opensourceecology.org/wiki/TechforTrade  These are simple versions of plastic extruders - which if scaled up and made more robust - can produce not only 3D printing filament, but larger extrusions.&lt;br /&gt;
&lt;br /&gt;
==3D Scanner==&lt;br /&gt;
&lt;br /&gt;
The 3D scanner allows for scanning of 3D objects to produce Computer Aided Design (CAD) models for reverse engineering. This is very useful - as we can take existing parts and digitize them for use as editable CAD models. A single camera can be used for photogrammetry, which is a computational technique for converting a set of pictures of an object taken from multiple angles into a 3D object.http://opensourceecology.org/wiki/Open_Source_Photogrammetry There is a number of open source programs that can do this. A 3D digital object can also be generated using multiple cameras, laser beams, or other light sources reflected from an object. As the simplest route, OSE  will build on existing work to develop the toolchain and procedure for photogrammetry - as that requires no hardware outside of a simple camera and a computer to process the images. If markers are used on objects, accurate CAD can be generated with proper dimensions. &lt;br /&gt;
&lt;br /&gt;
It gets more interesting: we can 3D scan internal features, too. This is known as industrial Computed Tomography (CAT) - essentially - a CAT scan for metal objects. By using an x-ray or gamma ray source - and then photographing an image - we can build a low-cost DIY CAT scanner.https://www.youtube.com/watch?time_continue=25&amp;amp;v=hF3V-GHiJ78  http://www.tricorderproject.org/blog/tag/openct/  Combined with an open source code base for image processing  from CERN, 3D industrial tomography scans can be obtained.https://home.cern/cern-people/updates/2016/09/new-open-source-medical-imaging-tools  &lt;br /&gt;
&lt;br /&gt;
==CNC Circuit Mill + Small Laser Cutter==&lt;br /&gt;
&lt;br /&gt;
We have already prototyped a circuit mill - the D3D CNC Circuit Mill.http://opensourceecology.org/wiki/D3D_CNC_Circuit_Mill  This shows a great example of the Unversal CNC axis modularity - where we have used the same motion system as in the 3D printer - but now strengthened the motion system by doubling the x axis to hold a small router. While the 3D printer is a non-contact manufacturing method - the circuit mill requires that the axes withstand contact forces of the milling operation. The strong, steel space frame of the D3D platform can handle these forces.&lt;br /&gt;
&lt;br /&gt;
Furthermore, other tool heads can be used on the Universal Axis. One useful example is a small 4W laser cutter, which cut up to ¼” plywood for prototyping purposes.&lt;br /&gt;
&lt;br /&gt;
Fig. The OSE CNC circuit mill and example circuits produced. The Router Tool Head is one of many tool heads that can be used on the Universal Axis system. A small laser is another, and can be retrofitted readily. The laser cutter toolhead allows for cutting cardboard for rapid prototyping. (4-picture - mill+product, laser+product)&lt;br /&gt;
&lt;br /&gt;
Prototyping with a laser cutter is important to the GVCS because the laser cutter can simulate the cutting that is typically done with a CNC torch table. Just like the CNC torch table typically cuts ½” thick flat parts out of sheet steel - the small laser cutter can cut parts out of paper stock. These parts can then be glued or fit together - just like the CNC-torch-cut metal parts are welded to make real-life 3D machines such as the CEB Press.&lt;br /&gt;
&lt;br /&gt;
Fig. Flat metal is used to generate 3D objects by welding. We thus use 2D cutting to create 3D objects.&lt;br /&gt;
&lt;br /&gt;
An open source project for a larger laser cutter - the 100W Lasersaur - is already well-developed. We can use this platform to build upon as well, to reduce cost from its current $7k to something more on the scale of $3k for a large format laser cutter. The Universal Axis could be applied here, such that only the laser system ($2000) remains as a significant cost - and the rest of the system is ($1000). This would be another great application of the Universal Axis to show its flexibility.&lt;br /&gt;
&lt;br /&gt;
Another useful example of a practical tool-head is a ceramic 3D printer head - which is an extruder for clay materials that can be fired to make functional ceramics. Examples of very useful ceramics are insulators and pottery - especially stovetop cookware made of flameware clay - which can replace commercial cookware and provide artistry in the open source Seed Eco-Home kitchen.&lt;br /&gt;
&lt;br /&gt;
Fig. The ceramic print head allows for the production of practical objects such as pots and pans for cooking, bringing artistry back into the kitchen.&lt;br /&gt;
&lt;br /&gt;
Collaborative Prototyping + Model Kits + Product Ideas + The Open Source Everything Store&lt;br /&gt;
&lt;br /&gt;
With access to the OSE Developer Kit - 3D printer, CNC Circuit Mill, and Laser Cutter - all as different tool heads on the same Universal Axis system - collaborators access a powerful capacity to prototype the larger machines of OSE. Using these tools, accurate scale models can be built. This can extend the collaboration capacity on OSE machine development significantly. There are 4 major ways that collaborative prototyping can be done using the 3-in-1 Universal Axis machine. &lt;br /&gt;
&lt;br /&gt;
First, there is collaboration is CAD verification. Computer Aided Design (CAD) is used in the OSE design process in order to save countless hours during the build. In a proper design process, it is easier to design in virtual CAD - and figure out how everything fits together - rather than going straight to a build and having to fit everything on the fly. The ability to model accurately in CAD is the power that allows OSE to do builds on the scale of a day - as opposed to weeks. However - this works only if the CAD is accurate, because if the CAD drafting is not accurate, it may be impossible to build a machine. CAD quality depends on the skill of the draftsperson. For this reason, it is important to verify the CAD as one of the steps that takes place prior to a build. If mistakes are not caught prior to the build, time and materials are wasted, people can get frustrated, and schedules are delayed.&lt;br /&gt;
&lt;br /&gt;
How do we guarantee that a machine can be built as drafted? With an accurate scale model. First, we must make sure that the CAD of individual parts is correct. This can be assured when accurate CAD files are available - whether the files are generated from measurements, provided by manufacturers, or 3D scanned with the open source 3D scanner. Second, we can verify the actual buildability. This can be done by laser cutting from paper the parts that would be CNC Cut from steel, and then 3D printing the components that we would otherwise get off-the-shelf. For the 3D printing - it is critical that we print every single part - up to bolts and nuts - so the entire assembly we can verify every single step of the build.&lt;br /&gt;
&lt;br /&gt;
This leads to the second use of collaborative prototyping - producing build instructional manuals and videos using the scale models. This allows contributors all over the world to produce meaningful content - without requiring that the contributors have access to a workshop. Since qulaity intstructionals production requires as much effort as the design work - this is another way to contribute to a large, parallel development effort.&lt;br /&gt;
&lt;br /&gt;
The third route to collaborative prototyping is the production of Model Kits for actual products. For example, the Seed Eco-Home lends itself very well for such modeling. Another company, Arckit (ref), is a good model for how we can design the model kit for the OSE’s collaboration with the Open Building Institute.&lt;br /&gt;
&lt;br /&gt;
Fig. Arckit is a great example for modeling. In the OBI case, the models correspond to real building panels and real build procedures. This makes the OBI Architecture Kit a tangible way for people to get involved in meaningful design of future house models.&lt;br /&gt;
&lt;br /&gt;
The OBI Architecture Kit lends itself well to 3D printing as well as laser cutting. 3D printed parts would snap together like Lego blocks.&lt;br /&gt;
&lt;br /&gt;
Another model kit that would be very useful to GVCS prototyping is the Machine Build Kit -  a kit for producing tractors, heavy equipment, and other automated machines. Combined with the OBI Arch Kit for buildings - this would produce the Civiliation Model Kit. The concept for the Machine Build Bit is a mixture of Lego Mindstorms, MakeBlock, Erector Set, Capsela, Box Beam Sourcebook, and Solar Micro Power Cube (all refs) - so that the system can run on solar power. The value proposition is that the kit would once again be based on real buildable parts - thus extending its use from childsplay to real design work.&lt;br /&gt;
&lt;br /&gt;
The OSE Developer Kit + Model Kits pave the way for the 4th route to collaborative prototyping - that of developing open source enterprise. These 2 kits are products in themselves - and can be used as the basis for collaborative business development of distributive enterprise (ref). The concept here revolves around reaching the $1T tipping point for the open source economy - the point at which mainstream adoption of open source economics is likely ($1T is calculated as the 10% tipping point at which viral adoption of open source economics can occur. This coincides with the next Enlightenment of humanity - see Tipping Point on the wiki - http://opensourceecology.org/wiki/The_Tipping_Point  ). This is as large as the combined revenue of Apple ($229B), Google ($79B), FB ($41B), Amazon ($178B), and Walmart ($486B) combined (Microsoft ($90B) - not includes so total is $1T.) - the latter being the single largest corporation in the world.&lt;br /&gt;
&lt;br /&gt;
OSE’s distributive enterprise approach to the tipping point is distributive. The core of OSE’s economic theory is that, by definition, a distributive enterprise serves its customers more effectively than any proprietary enterprise. Thus, a DE has a high likelihood of deposing the corporation http://opensourceecology.org/wiki/The_Corporation  as the dominant societal institution, replacing it with the next phase of the human economy - the open source economy. The transition is in our view likely - because the goal of a distributive enterprise is to produce free enterprise - defined as  distributing wealth most equitably. Current economic paradigms do not internalize distribution in their economic models. The next economy is achievable via full cost accounting and zero competitive waste, thereby achieving zero marginal cost (ref ZMCS). This proposition is simple to grasp, but most challenging to execute. We are not interested in DE as an ideology - but as a pragmatic proposition that simply meets needs more effectively - in an integrated sense -  than current models.&lt;br /&gt;
&lt;br /&gt;
The ask for distributive enterprise is to create the Open Source Everything Store - a networked and collaborative store based on Open Source Microfactories. That is - for people to collaborate on open source product development as a massive parallel effort. Decentralized, distributed, networked production is not a new idea - many people love and claim the idea as their own. To date no successful, economically-viable implementation exists, and certainly not open source. There were many attempts, from the FabLab, Local Motors, 1000 Garages, Ponoko - but none are both distributed and open source. The FabLab is a distributed microfactory concept, but none of its machines are currently open source. FabLabs are are externally funded, and none are used to run a successful business. Local Motors works on distributed production, but their designs and microfactory tools are not open source. 1000 Garages appears stalled. Ponoko and many operations like Ponoko are available. They are successful enterprises, but they do not use open source production tools or software. None of these projects provide open source enterprise information. Perhaps the best examples are 2: first, Lulzbot, which shares its machine designs and enterprise blueprints (blog post from 2014 visit, google Distributive Enterprise) - which makes it a fully open source hardware company - but it has a centralized business model. Second, there is the poster child RepRap project - which is the design/collaboration repository for open source 3D printers. RepRap is responsible for producing most of the consumer 3D printing industry’s companies - both open source and proprietary. (ref) However, RepRap in itself does not have a revenue model. Our own work is also based on the RepRap - it’s the basis that saved us hundreds of development hours - as we could simply build upon their designs. We do have a successfully-demonstrated revenue model of ongoing Extreme Manufacturing workshops.&lt;br /&gt;
&lt;br /&gt;
For The Open Source Everything Store (TOSES), any product developed must include open source blueprints, as well as open source enterprise documentation. Assets such as marketing materials, revenue models, business plans, projections, and entrepreneurship training - among others - must be included to facilitate startup by others. For successful startup - the enterprises themselves must be tested and proven. Thus, case studies of projections, actual revenue, and growth must be included. &lt;br /&gt;
&lt;br /&gt;
With as small an infrastructure as a Personal Microfactory with 3D printing, the CNC circuit mill, laser cutter, filament extruder, and off-shelf components - production of many valuable products can be distributed far and wide. Moreover, open design allows for extended product lifetime - as parts can be upgraded, modifications can be 3D printed, and breakages fixed with readily-accessible parts.  The success of TOSES  revolves around a massive parallel open source product development process - resulting in best-in-class products. These products are then produced by distributed players. Thus, a networked effort could reach substantial distributed production - and distributed sales volumes on the scale of Amazon. &lt;br /&gt;
&lt;br /&gt;
Our claim is that Distributive Enterprise has a good chance of succeeding because of its distributive nature. The cost structure of distributive development is efficient - as it relies on an open source process. We are assuming here that the zero marginal cost prediction - that everything trends to zero marginal cost - which is the competitive advantage of TOSES. However, zereo marginal cost is inherently impossible within the current system. The profit motive of the corporation prevents zero marginal cost, and leads to a permanent inefficiency in human economics. This can be resolved only by a transition away from the traditional corporate IPO form (ref). This is the reason why OSE proposes that a transition to the open source economy is inevitable. However, leading economic theorists such as George Gilder claim that human constructs are not inevitable - they have to be created. Thus, it remains up to human will to decide whether we would like to implement true-cost accounting to transition to the open source economy.&lt;br /&gt;
&lt;br /&gt;
The choice is up to us, and as such we are working on the DE model. Once open source product and enterprise blueprints are available - it means that everyone has access to them. This indicates that efficient production can be distributed into a networked form, which can gobble up Amazon and Walmart. Such a transition to the true-cost accounting economy is the promise of open source economics.&lt;br /&gt;
&lt;br /&gt;
In practice, this requires that open source microfactories, as well as open source materials production facilities - are distributed far and wide. These take abundant natural resources and convert them to a modern standard of living in a distributed way. People can produce with their personal microfactories. Using the 3D printer, circuit mill, laser cutter, and filament extruder - and off-shelf components - people can produce many household goods, electronic gadgets, toys, tools, kitchenware, small appliances, lab equipment (ref), and many others.  The size of the plastic industry alone is $2T - and the size of the injection molding industry is about $100B. Between vaccuum cleaners ($1B), consumer 3D printers ($1B),  cordless drills ($1B in the USA alone), drones, phones, cameras - the market size for those goods is on the order of hundreds of billions of dollars worldwide.  The current limit is 20% of GDP - the manufacturing sector of the economy - or about $16T.&lt;br /&gt;
&lt;br /&gt;
The centralized factory can become obsolete, and many parts of global resource flows can become localized. Specifically - as resource constraints to longer fuel resource conflicts and poverty - humans as a whole have - for the first time in world history - a chance for collective evolution. That simply means that the leading preoccupation transitions from making a living, surviving, or paying off debt - to thriving. This means that the multidisciplinary genius will become much more common - as society reaches a new level. An Einstein could be born every minute. (That makes it 1/250 - or 0.4% of the population.) This means that we transcend William Gibson’s — &#039;The future is already here – it&#039;s just not evenly distributed”. This means that most people will gain access to significant improvement in their quality of life. But this is also not a state of coerced equality as in communism - there will always be outliers who are more ambitious or skilled. But all have a good oportunity to thrive. &lt;br /&gt;
&lt;br /&gt;
CNC Torch and Larger Machines: Heavy Duty CNC Machining&lt;br /&gt;
&lt;br /&gt;
==CNC Torch Table==&lt;br /&gt;
&lt;br /&gt;
The universal axis can handle much larger forces - up to one thousand pounds - when it is scaled up. The universal axis has aleady been used with the 3D Printer and the CNC circuit mill. http://opensourceecology.org/wiki/Universal_CNC_Axis   &lt;br /&gt;
&lt;br /&gt;
We have already built a prototype of the CNC torch table using the Universal Axis, scaled up to a 2x3 meter working area:&lt;br /&gt;
&lt;br /&gt;
Fig: CNC Torch Table build workshop results. (https://www.facebook.com/marcin.jakubowski.378/posts/10213076897374250) &lt;br /&gt;
&lt;br /&gt;
The CNC Torch Table is near release status, and it will be the critical machine used in digital fabrication. The CNC Torch table will be used to cut all metal from flat sheets, which are then welded into 3D machines such as the brick press and tractor. The CNC Torch Table will also be used for cutting holes in 4” square tubing - which is our characteristic life-size erector set design.&lt;br /&gt;
&lt;br /&gt;
Typically, acetylene is used as a cutting gas. In the OSE case, the CNC torch table integrates with the oxyhydrogen production - where water is split into hydrogen and oxygen using electrolysis. These hydrogen and oxygen gases are used as the cutting gases. Oxyhydrogen cutting has been in use prior to the discovery of oxyacetylene cutting in 1903 https://en.wikipedia.org/wiki/Oxy-fuel_welding_and_cutting  - and was preferred for 2x the cutting speed with thick metal. Currently, oxyhydrogen is use whenever a clean cut is required. Otherwise, the gas is 2x as expensive as acetylene. The advantages of hydrogen are the ability to cut aluminum and stainless steel, which acetylene cannot do. Furthermore, if the open source oxyhydrogen generator is used with PV electricity at 1.5 cents per kWhr, then the cost of the gas should go down to about 5x lower than acetylene. Given these advantages, it is interesting to see that oxyhydrogen cutting is not used more commonly in the workshop. The apparent reason for this appears to be the lower price of fossil-fuel derived acetylene. Off-shelf on-demand oxyhydrogen generators appear to be expensive, so they would benefit greatly from being open-sourced. https://www.alibaba.com/product-detail/Gas-generation-equipment-for-oxgen-hydrogen_1950398042.html?spm=a2700.7724838.2017115.380.1b0840b43VI2AU  Hydrogen generators which can produce enough gas for cutting ½” steel are  are available for around $300, not including power supply. http://opensourceecology.org/wiki/Oxyhydrogen_Generator_Cost &lt;br /&gt;
&lt;br /&gt;
The OSE CNC torch table system includes a water bed to minimize smoke and prevent steel from warping while cutting, automatic height control which follows the surface of the metal for optimal cutting, an automatic ignitor, automatic gas control, open source controller, and open source controller software. Each of these piecces has been tested separately, and now we are putting the entire system together to a product that from 2018 onwards will be used to cut all steel for OSE in house. We cut steel for frames of the 3D printer, metal for the brick press, tractor, and just about every other GVCS tool.&lt;br /&gt;
&lt;br /&gt;
==Heavy Duty CNC Multimachine==&lt;br /&gt;
&lt;br /&gt;
The CNC Multimachine is a mill, drill, lathe and other tools in one machine, designed for modularity and flexibility, including rotary indexing and a grinding attachments. It can be used to produce engines and hydraulic motors, threaded parts such as bolts and pipe threads, as well as myriad other parts. The lathe has historically been the cornerstone of precision machining, and is a critical tool in civilization.  It is also another application of the OSE Universal Axis system - using the 2” rod size.&lt;br /&gt;
&lt;br /&gt;
Two other GVCS machines - the induction furnace which melts scrap metal to make virgin steel -  and the Mill which makes Rods and Wire - provide feedstocks for the CNC Multimachine.&lt;br /&gt;
&lt;br /&gt;
Fig. The 2” Universal axis can produce parts with accuracy of 10 microns, based on the deflection of 2” rods with 200 lb of force. This image shows the size comparison between the 2” version - and the 1” and 5/16” versions. The belt drive system can be identical to the smaller machines.&lt;br /&gt;
&lt;br /&gt;
We are interested in developing a core set of modules for a heavy duty machine - including mill, drill and lathe, with rotary and angle tables, plus capacity to function as a screw machine for making threads and bolts. We also include internal threads splines. &lt;br /&gt;
&lt;br /&gt;
Just like with the OBI Arch Kit (make sure reference is correct to rapid prototyping above), the Multimachine Construction Set will allow for modeling with 3D printed parts, which will correspond directly to real life - and thus serve as an educational kit and product. Together with the Multimachine Design Guide and FreeCAD workbench, people will be enabled to build their own multimachines and screw machines.&lt;br /&gt;
&lt;br /&gt;
For the 2” universal axis system, the practical limit is 400 lb of tool force with 0.001 precision and GT2 belt drive. For higher tooling forces, we must use lead screws instead of belts.&lt;br /&gt;
&lt;br /&gt;
The goal of the CNC multimachine is to produce electric motors, hydraulic motors, engines, cylinders, and valve blocks, among others. With a grinder attachment, the idea is to be able to achieve high precision, down to 0.0005, which is the positioning accuracy of the stepper motors at 16 microstepping and 1” GT2 pulleys.&lt;br /&gt;
&lt;br /&gt;
Using the Universal Axis, CNC linear motion control, and CNC rotary chuck control - we can get a wide array of functionality of a screw machine for making various precision parts. With a surface grinder, we can get precision parts down to 25 microns of tolerance. If we build a precision CNC surface grinder, then we can achieve up to 1 micron accuracy for making air bearings.https://www.youtube.com/watch?v=sFrVdoOhu1Q  Air bearings open the possibility of lubrication-free engines and high pressure pumps for storing hydrogen and a prerequisite for certain clean-room semiconductor manufacturing.&lt;br /&gt;
&lt;br /&gt;
==Robotic Arm - trainable for welding + 3D printing==&lt;br /&gt;
&lt;br /&gt;
The robotic arm is a powerful manufacturing tool as it is can move almost as flexibly as a human arm - but with increased precision and strength. Practical tasks that a robotic arm can accomplish depend on the end effector or tool that the arm is holding. For the GVCS, two good applications include automated welding and 3D metal printing using a MIG or TIG welder.&lt;br /&gt;
&lt;br /&gt;
Fig. Robotic welding - [nice pic] is useful for high quality welding to assist the open source renaissance woman. Spot welding or wire welding can be used.&lt;br /&gt;
&lt;br /&gt;
A useful application of robotic arms emerges from trainable robotic arms. Trainable robotic arms are arms which a human operator can train to move as needed. This eliminates complex programming tasks, making robotic collaborators accessible to the general public. An open source software platform already exists for robotic arms in the Robotic Operating System (ROS) project, including trainability.http://moveit.ros.org/  - such that the open source trainable industrial robot is around the corner by building on existing prior art. &lt;br /&gt;
&lt;br /&gt;
==Induction Furnace==&lt;br /&gt;
&lt;br /&gt;
An induction furnace is a device use to melt metal.  Metal can then be recycled - from scrap to useful stock. The advantage of the induction furnace over any other means of melting metal is a clean, energy-efficient and well-controllable melting process. In a typical induction furnace, a water-cooled copper coil with alternating current induces a current in a crucible of metal - hence the name Induction furnace - and that current heats up and melts the metal. Due to the heat being generated within the work piece, energy transfer is extremely efficient.&lt;br /&gt;
&lt;br /&gt;
Fig. In an induction furnace&lt;br /&gt;
&lt;br /&gt;
The induction furnace brings us from the stone and wood age - when stone and wood were the most common materials for making houses and machines - into the iron age - which is synonymous with the industrial age and modern civilization.  &lt;br /&gt;
&lt;br /&gt;
It may be said that modern civilization has culminated with the production of ball bearings. Bearings are a critical component that allows for engines, turbines of modern power to work - and precision machines that use precision ball bearings are used to manufacture these machine. Finally,  vacuum pumps and precision instruments - necessary in semiconductor manufacturing - depend on the use of bearings. As such, the information age today also relies on ball bearings - a combination of material science and precision manufacturing.&lt;br /&gt;
&lt;br /&gt;
==Metal Rolling, Rod &amp;amp; Wire Mill==&lt;br /&gt;
The induction furnace can be used in metal casting, where round rods or billets are cast and then used as feedstocks for metal rolling.&lt;br /&gt;
&lt;br /&gt;
Metal rolling uses rolling dies to shape metal into various profiles, from flat, to round, to angled. &lt;br /&gt;
&lt;br /&gt;
Fig. Metal rolling uses dies of various shapes to produce final stell shapes.&lt;br /&gt;
&lt;br /&gt;
Rolling of thin rounds - or rods - around dies and pulleys - is used to elongate and thin the rounds results in wire - a fundamental building block of civilization. Wire is used for house electrical wiring, suspension,  or fencing.&lt;br /&gt;
&lt;br /&gt;
Fig. A wire drawing machine starts from rod and stretches it to wire through a number of dies. The modular open source version can take rod and turn it into wire of any diameter.&lt;br /&gt;
&lt;br /&gt;
Metal rolling that occurs above the crystallization temperature (700C) is called hot rolling - and it takes less energy to do so as the metal is pliable. Cold rolling occurs at room temperature, and therefore requires more energy to deform the metal - but it also provides more accurate dimensions in the metal.&lt;br /&gt;
 &lt;br /&gt;
==Forging, Ironworker==&lt;br /&gt;
&lt;br /&gt;
The press forge is a heavy duty press than can be used to squeeze metal like butter. When metal is hot, it can be deformed into useful shapes by using a die. Bolt heads are made this way.&lt;br /&gt;
&lt;br /&gt;
Forges can take the form of press, drop, or roll rolling - preferably using the induction furnace for efficient forging. Cold forging may also be done, but that requires larger force for a given deformation.&lt;br /&gt;
&lt;br /&gt;
Forging is useful but the disadvantage is using specialized forming shapes or dies. Thus, the preferable route to forging would in many cases be subtractive machining, metal 3D printing,  or welding - as these are general-purpose procedures that do not require custom forms or dies.&lt;br /&gt;
&lt;br /&gt;
Fig. The press forge can shape hot or cold metal like butter.&lt;br /&gt;
&lt;br /&gt;
==Plasma Cutter, Welder==&lt;br /&gt;
&lt;br /&gt;
The plasma cutter, welder, and induction furnace are high-power electronics that use modern technology for efficiency. By using transistors and inverter circuits instead of large transformers, they can be light-weight and low cost - as the cost of power transistors is 10 cents/kW of power handling ability. This means that the simplest welder circuits can cost only a few dollars in electronic components (not counting wiring, structure, and the balance of system) to get industrial welders on the scale of 10kW (500Amps).&lt;br /&gt;
&lt;br /&gt;
Fig. Diagram of a welder. From first principles, a welder includes power handling electronics, wires, a case, cooling fan, and a welding gun with an electrode, and shielding gas for high quality welds.  In the simplest case - a tungsten electrode creates an arc to the metal and melts the metal, without using filler. This is an example of autogenous welding, where no welding rod or wire is required.  Welding is not complicated - the simplest electric arc welder is a 12V battery connected to a welding rod.&lt;br /&gt;
&lt;br /&gt;
A plasma cutter is a transistor-based power electronic device that cuts conductive metals with a plasma - or ionized gas.  The plasma cutter creates ionized air between an electrode and a work piece. The plasma heats the metal. By directing a focused stream of air around that plasma through a nozzle, the heated metal is oxidized and blown away, creating a clean cut. For comparison,  cut quality  in order of improvement is plasma cutting, oxy-fuel, waterjet, and laser cutting.&lt;br /&gt;
&lt;br /&gt;
Fig. Cut width - or kerf - of plasma, oxyfuel, waterjet, and laser cutting.&lt;br /&gt;
&lt;br /&gt;
Both the plasma cutter and welder are similar to each other. They have similar power electronic circuits.  For a welder or plasma cutter, the main difference is in the gun and electrodes. The gun in both cases has a large copper power wire and a gas line for shielding. For the MIG welder, it also has wire feed. The electrode is tungsten for the TIG welder and plasma cutter, and consumable welding wire for the MIG.&lt;br /&gt;
&lt;br /&gt;
More Power Electronics&lt;br /&gt;
&lt;br /&gt;
Is EDM practical? EDM is a high-voltage spark erosion system for cutting thick metals - where a moving wire at 10,000VDC spark-erodes metals as tiny sparks are established between the wire and metal to be cut. This system is insulated&lt;br /&gt;

&lt;br /&gt;
Disclaimer - Graph of completion&lt;br /&gt;
Here we discuss all the tools, but please remember that in Part 1 of the 4 Part Series, many of the machines are still on the drawing board.&lt;br /&gt;
&lt;br /&gt;
=Agriculture=&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
If you eat, you use a Tractor. Maybe not you directly, but the farmer that grew your food. And food is a $8T industry. The GVCS field agriculture machinery that support this $8T industry &amp;lt;ref&amp;gt;https://www.plunkettresearch.com/statistics/Industry-Statistics-Global-Food-Industry-Statistics-and-Market-Size-Overview/&amp;lt;/ref&amp;gt; are:&lt;br /&gt;
&lt;br /&gt;
Fig 1. The Tractor, Microtractor, Microcombine, Universal Seeder, Spader, Hay Cutter, Hay Rake, Baler, and Dairy Milker, and a Bakery Oven are critical tools of the $8T food industry.&lt;br /&gt;
&lt;br /&gt;
==Tractor, MicroTractor, Bulldozer and Power Cubes==&lt;br /&gt;
&lt;br /&gt;
The tractor is a cornerstone of a farm, construction, or other materials production industries. A tractor has the traction to pull things, and to do utility work with variou implements that can be added to a tractor and use the tractor’s mechanical power through a Power Take-off (PTO). As such, the tractor can be a swiss army knife of heavy duty work. For the smaller individual or home scale, we have the MicroTractor in the set, which is a small, walk-behind or ride-on tractor at the 16-32 hp size that can perform many gardening and utility functions and can fit in a smaller areas where a large tractor would be impractical. If we go up in scale - use a stronger frame and at least 64 hp, and add a bulldozer blade to the tractor - then we have a bulldozer.&lt;br /&gt;
&lt;br /&gt;
The tractor is a machine on the scale of 50-320 hp in the GVCS ecosystem, and unlike traditional tractors, we focus on modular power. We currently use small 16 hp engine units at $17/hp (ref), which is the lowest cost way to obtain engine power, while making maintenance very easy. Like in nature where a tree is made of many branches, our tractor is made of many small engine units. This way, the same design pattern can be used in the 16 hp tractor as in the 320 hp tractor. The price for using larger diesel engines is 2-4 times larger.  &amp;lt;ref&amp;gt;http://opensourceecology.org/wiki/Diesel_Engine_Cost &amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
By using the modularity concept, we create our typical construction set approach for heavy machines. For example, if a large tractor frame is fitted with a bulldozer blade - then we don’t require a separate bulldozer in addition to a tractor. This saves a lot of resources - making technology significantly lower cost to maintain. Exploring the limits of modularity, we found that it is much less expensive to scale our machines usig modular and overbuilt parts that make sense both for small and large machines. For example, we can use 4 of our identical track units, each rated for up to 80 hp - Our track unit, for example, allows for a $30k version &amp;lt;ref&amp;gt; http://opensourceecology.org/wiki/Modular_Track_Unit_v18.01&amp;lt;/ref&amp;gt; that matches the traction of a Cat D7 - a sizeable cost savings comprd to a base price of ½ a million. &amp;lt;ref&amp;gt;https://www.caranddriver.com/reviews/caterpillar-d7e-feature-test &amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Fig. Pattern Language for a Tractor - up to automated control.&lt;br /&gt;
&lt;br /&gt;
The key is making it easy and quick to interchange parts - from small parts to large implements. This is a great challenge for advanced industrial design.&lt;br /&gt;
&lt;br /&gt;
Fig. Industrial smaller parallel and trained configuration. OSE machines can be designed like this, but higher flexibility of the OSE platform can allow for an improved configuration.&lt;br /&gt;
&lt;br /&gt;
Fig. The flexibility of a modular OSE tractor. The modular OSE tractor can be built from the same components, but apply to 16 hp or 320 hp machines while using the same over-engineered components such as the ½” thick steel tracks &amp;lt;ref&amp;gt;Current design is rated for  rated for 40 hp per track or 80 hp with double drive, . (ref - do calculations) and 3600 lbs or 7200 of pull each. Thus, a four-tracked machine can have 29,000 lb of pulling force with direct drive using our current 15k in-lb motors.&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
==Spader, Seeder, Bulldozer==&lt;br /&gt;
&lt;br /&gt;
Your food today is grown largely by tractor-driven  tilling and seeding, unless you’re a breatharian. Tillage in the OSE system chooses the spader as a more progressive technology compared to the age-old plow. &lt;br /&gt;
&lt;br /&gt;
Fig. (Image of 1800 steam tractor with 50 bottom plow) &lt;br /&gt;
&lt;br /&gt;
The spader works essentially like  a bunch of shovels moving rapidly - which till soil without crating a hardpan typical of the more common plow. Manufacturers claim that spading uses 40% less fuel than plowing - because a spader can combine tilling, harrowing, and planting in one operation. &amp;lt;ref&amp;gt;https://www.farmax.info/PDF/Magazine-Farmax-EN.pdf &amp;lt;/ref&amp;gt; A plow, which drags through the soil, requires a lot of wheel-to-ground  traction, whereas a spader requires very little - thus avoiding soil compaction. It takes a spader under 9 minutes and 2 gallons of fuel per acre of field - such that feeding Dunbar Village &amp;lt;ref&amp;gt;A village of 200 -  based on Dunbar’s number https://en.wikipedia.org/wiki/Dunbar%27s_number &amp;lt;/ref&amp;gt; would take 6 hours to plant for a whole year of crop &amp;lt;ref&amp;gt;Assuming field crops planted with a seeder, not slips like sweet potatoes. http://opensourceecology.org/wiki/Acres_Needed_to_Feed_Dunbar_Village &amp;lt;/ref&amp;gt;Thus, one day to plant, two days to harvest - and the village has food for the year. &lt;br /&gt;
&lt;br /&gt;
The tractor and universal seeder is an example of how we approach multiple purpose machines. The tractor is a large-size swiss army knife for doing many different tasks. The Universal seeder is designed to plant all types of seed, from alfalfa to wheat, to tubers, and to live plants like sweet potato slips. Modifying the device rapidly is key to this flexibility.&lt;br /&gt;
&lt;br /&gt;
Fig. Swiss army knife tractor concept&lt;br /&gt;
&lt;br /&gt;
The point of using powerful machines wisely is that in the OSE perspective of lifetime growth -  life could become easy so we can focus on evolving as humans. Our experiment involves building a college campus where peole live this. When they graduate, they know how to organize a village to spend 2 hours per day working on survival, and then the rest of their life they pursue their highest ideals.&lt;br /&gt;
&lt;br /&gt;
The experimental village thus requires one farmer who is employed 3 days of the year, assuming the equipment does not break down, and generates 30 acres * $20k/acre of sweet potato, and $5k/acre for 10 acres of wheat if that is turned into bread  - or $650k worth of food for the community with direct marketing. That is $27k/hour if baking is automated - a decent pay, but not like the $25k/minute rate of Warren Buffett &amp;lt;ref&amp;gt;http://www.businessinsider.com/what-warren-buffett-makes-per-hour-2013-12  &amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Of course these are unreasonable figures, but they do represent the idea. The only way that customer acquisition and marketing costs do not ruin such ideals is in the case of direct marketing - where the on-site farmer-scientist provides for a captive audience of the Dunbar village. If each person eats about $2600 per year &amp;lt;ref&amp;gt;https://www.google.com/search?q=average+cost+of+food+per+year&amp;amp;oq=average+cost+of+food+per+year&amp;amp;aqs=chrome..69i57j0l5.7243j1j7&amp;amp;client=ubuntu&amp;amp;sourceid=chrome&amp;amp;ie=UTF-8&amp;lt;/ref&amp;gt;, feeding 150 people would involve revenues of $390k - but that would be a full time job. We will look more carefully at the business model for resident farmer agriculture in the Enterprise chapter.&lt;br /&gt;
&lt;br /&gt;
Now it would take more time to do a diversified operation, but this is shown just as a baseline to see what’s possible in terms of the effort.  Several Ph.D.’s can be granted to develop a diversified, 40 acre subscription farm, using open source equipment and a captive market, or Local Food Nodes as part of a distribution platform.  &amp;lt;ref&amp;gt;https://localfoodnodes.org/&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The OSE project will develop such a food enterprise both for its campuses and for the outside community - once all the farming machines are done, the aquaponic greenhouse production is optimized, and derivative food processing tools are developed.&lt;br /&gt;
&lt;br /&gt;
The open source tractor can be built at a cost of $125/hp at a scale of 80 hp, compared to $370-$1000 for other brands. It is useful to understand the basic cost breakdown based on off-the shelf parts:&lt;br /&gt;
&lt;br /&gt;
Fig. Cost breakdown of a tractor by Frame, engine, hydraulics, control, automation, and balance of system - $125/hp. (p590MJ)&lt;br /&gt;
&lt;br /&gt;
The cost advantage is less visible at the 32 hp MicroTrac, at $160 per hp - though but a comparable mahine like the tracked Toro Ding costs around  $1000/hp (ref).&lt;br /&gt;
&lt;br /&gt;
Fig. Microtrac with tooth bar bucket can till your garden, and provide valuable utility work. It is an indidspensible utility machine for any prosumer.&lt;br /&gt;
&lt;br /&gt;
==Hay Cutter, Rake, Baler==&lt;br /&gt;
&lt;br /&gt;
If farm animals are involved, then you need these. Or if you want to move large quantities of materials, then a bale is a useful form: from a bale of hay, brush, cotton, cardboard, or plastic - bales allow large scale moving of materials. Bales of aluminum cans are likewise useful for melting down in your induction furnace. If you are making fuel pellets from biomass, plastic pellets for making 3D printer filament - you will need a baler to make 1 ton bales.&lt;br /&gt;
&lt;br /&gt;
==Dairy Milker== &lt;br /&gt;
For animal husbandry, hay baling stores hay for the winter. Unless you are talking about the fish in your home aquaponic system. Dairy products themselves are $116B &amp;lt;ref&amp;gt;https://www.ibisworld.com/industry-trends/market-research-reports/manufacturing/food/dairy-product-production.html &amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
of the global economy - hence the relevance of the dairy milker. &lt;br /&gt;
&lt;br /&gt;
Table: values of the overall food, dairy, cattle, vegetable markets worldwide.&lt;br /&gt;
Combining the dairy milker with computer vision and automation, we envision a solar robotic milker - our MicroTrac with a milking stall - that drives up to a cow to milk her, and then brings the milk back for storage and processing. This allows field milking without human labor for small diversified robofarms that combine the best of regenerative agriculture with modern tehnology to relocalize farming.&lt;br /&gt;
&lt;br /&gt;
Fig. Robotic milker&lt;br /&gt;
==MicroTrac== &lt;br /&gt;
&lt;br /&gt;
A very interesting use arises with a small, solar, robot tractor - the MicroTrac driven by a solar panel. By adding a $10 Raspberry Pi Zero Controller &amp;lt;ref&amp;gt;https://www.adafruit.com/product/3400?gclid=EAIaIQobChMI2rz0mcnd2gIVCzlpCh3MpQgIEAQYAiABEgKi7_D_BwE&amp;lt;/ref&amp;gt; and a $100 solar panel you can be your robotic tractor - for agriculture and other. You can now mow your lawn automatically, and even pelletize it for fuel for a pellet stove. This is possible because today - advanced microelectronics such as the Raspberry Pi is 100 times faster that the first supercomputer, which cost $9M &amp;lt;ref&amp;gt;https://www.theregister.co.uk/2008/01/05/tob_cray1/ &amp;lt;/ref&amp;gt; in 1975.&lt;br /&gt;
&lt;br /&gt;
Fig. A solar-driven MicroTrac concept with solar panel and $50 arduino controller can provide autonomous agriculture &lt;br /&gt;
&lt;br /&gt;
==Bulldozer==&lt;br /&gt;
&lt;br /&gt;
Now add a bulldozer blade to a beefed up, tracked tractor - and you have one of the most powerful devices for regeneration - or destruction - depending on how you use the machine. Bulldozers are powerful earth moving machines - to build roads, grade house foundations, and in agriculture - to build regenerative earthworks for water and erosion. The biggest example is the 12,000 square miles that have been regreened in China - the Loess Plateau. &amp;lt;ref&amp;gt;John Liu reported on this - http://www.aquinta.org/news/2016/10/6/greening-the-desert  &amp;lt;/ref&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Fig.&#039;&#039;&#039; Loess Plateau reforestation&lt;br /&gt;
&lt;br /&gt;
So, if you ever drove on a road - you used a bulldozer. Maybe not you, but whoever graded the road base. &lt;br /&gt;
&lt;br /&gt;
==Microcombine==&lt;br /&gt;
&lt;br /&gt;
The Microombine is used to harvest grains and seeds of any type. This is the core of human harvests world wide. For the OSE case, we have a much more flexible and modular machine in mind. Based on our module-based aproach, we can use the same drive platform as the tractor&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Fig&#039;&#039;&#039;. Showing the base drive platform that can be used &lt;br /&gt;
&lt;br /&gt;
==Bakery Oven==&lt;br /&gt;
&lt;br /&gt;
Humble bread is a $419B global market https://www.ibisworld.com/industry-trends/global-industry-reports/manufacturing/bakery-goods-manufacturing.html . It is the 12th most popular food in the world. https://www.farmflavor.com/at-home/what-is-the-most-popular-food-in-the-world/  And 49% of Americans eat bread  https://www.smithsonianmag.com/smart-news/each-day-50-percent-america-eats-sandwich-180952972/ . &lt;br /&gt;
&lt;br /&gt;
Now bulldozers, tractors, and combines are all good - but the next step for gobal agriculture is the transition to  perennial polyculture  https://www.youtube.com/watch?v=KpJR2yfLUU0  , with only a small fraction of tillage ramaining.&lt;br /&gt;
&lt;br /&gt;
=Construction - 13 Tools=&lt;br /&gt;
If you want to build a charter city or a smaller campus, you will need construction equipment - and a trencher to put in gigabit internet fiber between the locations.&lt;br /&gt;
&lt;br /&gt;
The tools in the construction part outside of the tractors include the backhoe, trencher, cement mixer, sawmill, CEB press, well-drilling rig, soil pulverizer, hammermill. The universal rotor is a tool used in other sectors of the GVCS - and the SeedHouse is a living machine. &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Fig. 13 tools of the construction part of the Global Village Construction Set.&lt;br /&gt;
&lt;br /&gt;
==Backhoe, Trencher, Cement Mixer==&lt;br /&gt;
&lt;br /&gt;
The backhoe or excavator can be used to dig aquaponic ponds, foundation trenches. It can be used to remove stumps, do trenching, and with a grapple it can be used to lift logs or to hoist heavy objects. Backhoes are relatively simple devices - a set of pivot joints that use hydraulic cylinders for their motion - producing thousands of pounds of digging force at the touch of control levers. There are both side-to-side moving backhoes, but a 360 degree rotating backhoe is much more flexible. The small side to side version can be used on a front quick attach of a tractor.&lt;br /&gt;
&lt;br /&gt;
Fig. OSE backhoe from 2010 https://www.google.com/search?q=ose+backhoe&amp;amp;client=ubuntu&amp;amp;hs=ToH&amp;amp;source=lnms&amp;amp;tbm=isch&amp;amp;sa=X&amp;amp;ved=0ahUKEwjLzZKelOLYAhULbawKHQo-DVwQ_AUICigB&amp;amp;biw=1351&amp;amp;bih=731#imgrc=t8j52U9--mn6BM:  mounted on he original lifetrac, a small one used for water line trenching in 2012 http://opensourceecology.org/wiki/File:Bhp1.jpg , and a larger one from 2013 https://www.youtube.com/playlist?list=PL6Jpysxw3Ty-oH4bggp32PR_rPWr8bKC1 . Next iteration is the 360 degree backhoe with remote control drive to facilitate hydraulic line routing.&lt;br /&gt;
&lt;br /&gt;
The trencher in the original GVCS icon is a wheel trencher. We built 2 prototypes, and the next iteration will be a chain-based trencher based on our favorable experience with oversized chain drive on the bulldozer tracks.&lt;br /&gt;
&lt;br /&gt;
Fig. OSE Trencher http://opensourceecology.org/wiki/Trencher - 2011 and 2013 builds.&lt;br /&gt;
The cement mixer is indispensable. Cement has been used in ancient Rome and in mesoamerican temples. Scotland&#039;s County Cork had 23,000 lime kilns at one time - had one kiln per 80 acres. Wood or coal was used as fuel. http://www.lowtechmagazine.com/2013/09/lime-kilns.html  http://www.chapelgatehome.uk/our-blog   Portland cement took over lime cement in the last 100 years, but lime concrete is favorable in foundations becaue it doesn’t crack as easily as Portland. Using modern appropriate technology, lime cement production in solar microfactories is a viable enterprise at the 1 ton per day scale using an open source microkiln the size of a refrigerator. Limestone goes in one end, and lime comes out the other. With such small appliances costing around $1k, cement production can be distributed - while making cement production carbon neutral, annihilating  the current 5% CO2 emission share of the the concrete industry.https://en.wikipedia.org/wiki/Environmental_impact_of_concrete  This is possible in about 50% of America, where the bedrock is made of limestone. That’s a $10B industry in the USA alone.https://en.wikipedia.org/wiki/Cement_industry_in_the_United_States &lt;br /&gt;
&lt;br /&gt;
The cement fryer - a rotary lime kiln - is much like the cement mixer: a Universal Rotor with a heating element. A rotating pipe heated by PV, and an Arduino microcontroller to measure temperatures and guide the process to efficient completion. While not part of the 50 GVCS technologies, it’s a ready derivative:&lt;br /&gt;
&lt;br /&gt;
Fig. PV of the Open Source Materials Production Facility, a solar Power Cube, a Universal Rotor, metal pipe and an Arduino microcontroller constitute the lime cement maker.&lt;br /&gt;
&lt;br /&gt;
If we want to go to the essence of construction, take the backhoe excavator, chase it with a bulldozer with ripper shanks, and then rock under a site could be extracted to build a pond. This rock, if limestone, is feedstock for your lime kiln. In some places, rock outcroppings make access to limestone easy.&lt;br /&gt;
&lt;br /&gt;
==CEB Press , Soil Pulverizer, and Sawmill==&lt;br /&gt;
&lt;br /&gt;
The Compressed Earth Brick press and sawmill are critical tools for construction in that they produce materials. The CEB Press allows one operator to load raw dirt right from the building site to produce about 5000 bricks in a day - enough for a small house. &lt;br /&gt;
&lt;br /&gt;
Fig. The CEB Press is the first machine that we have prototyped, and it is ready for widespread replication around the world.&lt;br /&gt;
&lt;br /&gt;
We have used the soil pulverizer to prepare soil for pressing CEB blocks. The soil pulverizer was used to both pulverize the soil, and its bucket was used to press bricks for CEB construction.&lt;br /&gt;
&lt;br /&gt;
Fig. Soil pulverizer - Aidan on the tractor + loading the brick press by Yoonseo&lt;br /&gt;
&lt;br /&gt;
Our next step on the CEB press is a full soil conditioner which pulverizes soil, adds cement at a measured quantity of 5%, and then loads the mixture into the CEB press - to allow for production of high quality, stabilized block.&lt;br /&gt;
&lt;br /&gt;
Fig. The soil conditioner accepts raw soil from a tractor loader, mixes a measured amount of cement, and loads the prepared mixture into the CEB press for effective production of stabilized block at 12 cents ( 10 cent cement cost for a 20 lb block, and 2 cents gasoline cost). per block in materials. This means that we can build a 1’ thick CEB wall section for $50 in materials.&lt;br /&gt;
&lt;br /&gt;
The sawmill is a machine that can produce dimensional lumber - a staple of construction. Our sawmill is a variety known as a swing-blade sawmill, which has a single blade that can rotate 90 degrees and make a dimensional piece of lumber by going forward and back on a piece of wood.  We chose the dimensional sawmill for its simplicity over a bandsaw mill, as blade sharpening is much easier - and maintenance is the larger cost of any equipment if that equipment is designed for a lifetime.&lt;br /&gt;
&lt;br /&gt;
The sawmill is a good example of how we can use GVCS product ecologies to reduce complexity and reduce the cost of equipment. We design not just individual machines, but machine ecosystems that feed off one another. We can obtain drastic cost reduction by borrowing existing modules from the GVCS. For our case, it makes sense to design the sawmill as a Bobcat standard quick attach implement. We borrow the tractor as a  quick attach point, so that we do not need a bed upon which the sawmill head would otherwise ride. We borrow 32 hp from the tractor Power Cubes. We also  borrow the hydraulic motor which we attach with hydraulic quick-connect hoses. Thus, we have essentially stripped down the entire sawmill to the long carriage with the cutting head - saving $2k https://www.ebay.com/itm/30hp-Kohler-Engine-1-1-8-D-Command-15Amp-Exmark-CH750-0026/132423001888?epid=26011371639&amp;amp;hash=item1ed506a720:g:4YUAAOSwH2VaS3-h  on the engine, $2k https://sleequipment.com/dovetail-utility-trailer-7x20-with-3500lb-axles.html?fee=8&amp;amp;fep=524834&amp;amp;gclid=EAIaIQobChMIws349azn2AIVBqxpCh1rMwbpEAQYASABEgIeHPD_BwE  on a trailer. The greatest advantage would be the setup time - if designed as a quick attach implement, the sawmill can be taken to a log, rested right by the log, and ready for action - as compared to systems where the carriage base must be set up or the log moved into cutting position. If the sawmill can straddle right over a log or be raised with the loader arms, there is no limit ot the size of log that the mill can handle. &lt;br /&gt;
&lt;br /&gt;
Fig. The simplicity of the OSE swing-blade sawmill involves a long linear track mounted as an implement for the tractor. To provide 3 axes of motion - the loader mounting includes height adjustment (z motion), and a lightweight cantilevered head provides side-to-side motion. The cost of about $1500 is significantly lower than the $15k http://www.dltimbertech.com/dl-180-swing-blade-sawmill-10-x-20.html   minimum for a comparable 32 hp sawmill. (ref)&lt;br /&gt;
&lt;br /&gt;
And the sawdust that we generate can be used as animal bedding, insulation, or it can be pelletized to make fuel pellets.&lt;br /&gt;
&lt;br /&gt;
==Universal Rotor==&lt;br /&gt;
&lt;br /&gt;
The Universal Rotor is a fundamental building block for just about any moving machine. It is a combination of rotary motion and a useful tool-head. As a design pattern consisting of a shaft, bearings, and a motor -  a wide array of working tools can be attached to it - so that the Universal Rotor can constitute a drill, a wind turbine,  a wheel, a hammermill, cement mixer, sawmill - etc  - essentially any machine at any size - from small cordless electric drills to a larger 50kW rotor of a wind turbine. &lt;br /&gt;
The Pelletizer , Chipper/Hammermill, Dimensional Sawmill, Rototiler/Soil Pulverizer, Cement Mixer, Well-Drilling Rig, 50 kW Wind Turbine, Microcombine Thresher, and Bioplastic Extruder are direct applications of the universal rotor, and combined with precision machining structures, the Universal Rotor also include the heavy duty CNC Multimhttps://www.opensourceecology.org/portfolio/pelletizer/achine with lathe, drill press, slow cutoff saw, surface grinder, and other machines of fabrication.&lt;br /&gt;
If we can build a Universal Rotor, a Power Cube, and weld together  a supporting structure - then we have - broadly speaking - built 23 of the 50 machines of the GVCS. For example, if we consider the electric motor - it is a a shaft, 2 bearings, a structure, and the ‘tool head’ could be considered the electrical windings that make the shaft spin. Or, if we consider the metal lathe - a part of the Multimachine - then it is clear that the lathe consists of a heavy shaft, 2 heavy bearings, and the tool-head is a chuck for holding work-pieces.&lt;br /&gt;
&lt;br /&gt;
==12. Well-Drilling Rig and Chipper/Hammermill==&lt;br /&gt;
The well-drilling rig is a machine used to dig deep water wells. It consists of a universal rotor which uses 3” (https://www.aquascience.net/grundfos-10sq05-160-230v-10gpm-1-2hp-230v-2-wire-96160140-3-stainless-steel-submersible-well-pump?gclid=EAIaIQobChMIlt-S3PDn2AIVC6tpCh369g34EAQYASABEgJr__D_BwE. 10’ of this pipe store 4 or 6.5 gallons of water. ) or 4” drill pipe to drill down to a depth of 100m or more using hydraulic rotary drilling. In this method, a stream of water is sent down the pipe during the drilling operation to send up tailings and soften the area of the drill point. A heavy duty hydraulic motor spins the drill rod - and new sections of drill rod are attached one after another. When the operation is done, the drill pipe is left underground and a submersible pump is inserted to pump water from the well.&lt;br /&gt;
Fig. A hydraulic deep well pump drilling system explained. The water swivel is the key part here. Otherwise 3” pipe that can be used as  drill pipe and casign is $12/foot. https://www.discountsteel.com/items/Galvanized_Steel_Pipe.cfm?item_id=172&amp;amp;size_no=11#skus  &lt;br /&gt;
The chipper/hammermill is another application of a universal heavy rotor with swinging or fixed blades. This machine shreds or pulverizes materials, and can be as small or large as needed.&lt;br /&gt;
Fig. Hammermill variations with various blades to chip wood or crush rock. A modified version of a heavy rotor can be a grinder. The scale can be from the largest - shredding cars - to the smallest - with small electric motors - if you have hydraulic drive and electric drive.&lt;br /&gt;
&lt;br /&gt;
==The House - Seed Eco-Home and Aquaponic Greenhouse==&lt;br /&gt;
&lt;br /&gt;
The Seed Eco-Home is a living machine - and becase it is the single largest cost of living today, we dediced to include that in the GVCS. (Initially, the house was not in the GVCS - but it was added as the Microhouse.) The Seed Eco-Home is the culmination of all the construction machines put to use. Homes are  also about  $3T (https://en.wikipedia.org/wiki/Construction#Industry_characteristics - residential construction is about ⅓ of all construction) market worldwide - which if open-sourced, could provide 30 million regenerative housing jobs for open source home building entrepreneurs Earning $100k each per year. This is 30 million potential collaborators - through we need only about 1000 at this time.&lt;br /&gt;
&lt;br /&gt;
The OSE/OBI https://www.openbuildinginstitute.org/  Seed Eco-Home is a an affordable, expandable eco-home that can be built for ⅓ the cost of a typical home, while including ecological features. Rather than building a large house, we propose starting with a seed home, and then growing it as the need arises. &lt;br /&gt;
&lt;br /&gt;
We are pushing ecological limits in our autonomous house design. The house is  off-grid with PV, provides its own cooking fuel from a biodigester, includes roof-top rainwater collection, and grows its own food with an aquaponic greenhouse. Mowed lawn or biomass is used to provide heating biomass pellets for a hydronic stove that is fueled by pellets. The eventual product vision is a house that  produces fuel for cars as compressed biogas or compressed hydrogen - by splitting water. Thus, we are correcting the oil and gas industry with 100% renewable energy, using simple, proven technologies. We are not relying on advancements in battery technology as a prerequisite to sustainable transportation, and by not requiring scarce lithium for batteries, we are aiming for an abundant and environmentally friendly energy future. http://www.kitco.com/ind/Albrecht/2014-12-16-How-Green-is-Lithium.html  We favor rooftop PV plus electrolysis as the preferred route for transportation fuels, where every house becomes a gas station. Using medium pressure electrolyzers that can produce hydrogen up to 33 atmospheres without needing a compressor - we can readily store hydrogen in large propane tanks or higher pressure steel pipe. &lt;br /&gt;
&lt;br /&gt;
Fig. Seed Eco-Home&lt;br /&gt;
&lt;br /&gt;
Fig. Aquaponic greenhouse glamour shot.&lt;br /&gt;
&lt;br /&gt;
The aquaponic greenhouse is designed to provide a year-round supply of fresh eggs, vegetables, fish, and mushrooms. The goal is to include automated planting with a small Farmbot (https://farm.bot/ . By Shuttleworth Fellow friend Rory Aaronson.), where the resulting deep pots are planted in the  towers. With a 1000 plant growing capacity in the main towers, the greenhouse can provide a robust salad daily, where we plant and harvest 15 plants per day from a small 800 sf greenhouse. A mushroom yield of 1lb is obtained per week from a tower that takes only 1 square foot. We also intend to use automated 3D printed aerial drones for planting seeds directly into towers - a great example of useful product ecology. Local food addresses the issue of food miles, where food travels an average of 1500 miles in the USA before ending up on someone’s plate. https://cuesa.org/learn/how-far-does-your-food-travel-get-your-plate  This is one of the numerous inefficiencies that will be addressed by a more efficient, open source economy. This brings us to transportation.&lt;br /&gt;
&lt;br /&gt;
=Transportation. =&lt;br /&gt;
&lt;br /&gt;
The microcar, truck, electric motor, and hydraulic motor are the 4 GVCS machines directly related to transportation. &lt;br /&gt;
&lt;br /&gt;
The worldwide production of cars is a total of 95M per year, 75% of which is done by the top 15 companies. https://en.wikipedia.org/wiki/Automotive_industry#World_motor_vehicle_production  This lends itself to massive distribution of power. The OSE paradigm proposes instead that there would be on the order of million distributed enterprises - essentially one per 10,000 people. Each facility would produce cars on the scale of dozens or hundreds in the community-supported manufacturing (CSM) scenario. Thus, car producers replace car dealership  - as the producer takes to dealing.  This would go well with a gas station at every home, splitting Seed Eo-Home rooftop water for fuel at a cost of 80 cent per gallon of gasoline equivalent. http://opensourceecology.org/wiki/Hydrogen_Production &lt;br /&gt;
&lt;br /&gt;
Fig. Seed Eco-Home to car fuel infrastructure consists of rooftop water collection, 10kW of PV panels, a storage tank for hydrogen, and compression to 200 bar. Piece of cake if you consider not doing this - wars for oil. This gives us about 100 miles of fuel worth per day in a 100mpg microcar.&lt;br /&gt;
&lt;br /&gt;
==OSE Microcar==&lt;br /&gt;
&lt;br /&gt;
The OSE Microar is a Hydrogen Hybrid Hydraulic (H3) vehicle. Hydrogen is chosen because an internal combustion (ICE) engine running on hydrogen is twice as efficient (40%) as a normal ICE (20%), and only 25% under the 50% efficiency of fuel cells. http://environment.yale.edu/gillingham/hydrogenICE.pdf A hydraulic drive train (71% efficiency) - has a higher efficiency than a continuously variable transmission (60%) for fuel cell electric vehicles - meaning that the humble hydrogen hydraulic car gets a higher mileage than a fuel cell car, at significantly lower cost. At a design weight of only 850 lb, less than ¼ of a typical car, the OSE microcar focuses on moving the passenger, not a large chunk of metal accessory to the core purpose. Lighter cars have a good safety record. Before the S.U.V. boom, the country (USA) had the world&#039;s lowest highway death rate.http://www.nytimes.com/2004/05/05/business/averag e-us-car-is-tipping-scales-at-4000-pounds.html  Additionally, gas mileage for the OSE Microcar is specified for 100mpg. While not as testicular as a Tesla, the OSE specification requires higher self-esteem on the part of the driver to accept acceleration from 0-60 of 12 seconds, as opposed to under 3 seconds for a Tesla Model S.https://en.wikipedia.org/wiki/List_of_fastest_production_cars_by_acceleration&lt;br /&gt;
&lt;br /&gt;
Fig. The OSE Microcar concept.&lt;br /&gt;
&lt;br /&gt;
Are smaller cars safer? This is controversial. https://www.ptua.org.au/myths/smallcar/  Physics says that energy of motion is proportional to v squared, and data shows that 56% of car deaths are single-car collisions. So unless you are going to hit another oncoming car or an immovable object like a large tree, your tiny car of under 1000 lb  has 36x less energy to dissipate than a Chevy Suburban of 6000 lb. And, the lightest car - the Smart Carfortwo at 1800 lb http://driving.ca/hyundai/accent/auto-news/news/these-are-the-ten-lightest-cars-you-can-buy-in-2015  and it certainly does get eaten up in a frontal 2 car collision with a larger car. And crashes took more than 37k lives in the US http://www.iihs.org/iihs/topics/t/general-statistics/fatalityfacts/state-by-state-overview#Crash-types  , with 20-50x more if injuries are counted. http://asirt.org/initiatives/informing-road-users/road-safety-facts/road-crash-statistics (are injuries better or worse in large cars?)&lt;br /&gt;
&lt;br /&gt;
But this is all before self-driving cars enter the scene - which have been tested for 0 driverless car crashes over 1.8 million miles by Google - with 13 fender benders caused by other cars. http://bigthink.com/ideafeed/googles-self-driving-car-is-ridiculously-safe  In other words, the case is there for super-small, super-efficient cars that are robotically controlled. &lt;br /&gt;
&lt;br /&gt;
What we have in mind follows the standard of the 200 mpg fuel efficiency of the VW  L1 first prototype car, at 640 lb weight, 8 hp, top speed of 75 mph, with tandem seating for 2. https://en.wikipedia.org/wiki/Volkswagen_1-litre_car. The efficiency dropped to 170 mpg in a hybrid version - http://gas2.org/2009/09/14/volkswagens-diesel-hybrid-1l-concept-gets-170-mpg-available-by-2013/  If OSE achieves the same with 16 hp instead of 8 hp, and using hydraulics while not needing to go to a hybrid drive-train that apparently reduced its initial mileage performance - then we will have a major victory for open source-  Hydraulic accumulators may be used for peak power.  Plus, we’d like to achieve this with hydrogen as fuel in later versions.&lt;br /&gt;
&lt;br /&gt;
More specifically - our model is an H3E car - including a hybrid electric component.  The hydraulic component is a peak power electric-hydraulic micro-Power Cube of about 40 lb additional weight - powered by the onboard starter battery for its cranking amps.  This additional 30 seconds of a starter battery would double the power of the 16 hp engine - such that burst of energy for passing and sudden acceleration can be achieved easily.&lt;br /&gt;
&lt;br /&gt;
==B The Solar Car==&lt;br /&gt;
&lt;br /&gt;
The Solar Challenge is a fascinating event that shows PV-covered cars traveling 62 mph average across Australia. Granted that the driving is in expensive prototypes ad a sunny country - only in daytime - this still bodes well for the feasibility of solar transportation. The typical cars used are small - surface area of a Toyota Prius - and the OSE version would be twice as large 24x8 feet for 3kW of installed PV + 44 lb Lithium ion batteries + 2.5 kW small engine. http://opensourceecology.org/wiki/Solar_Car This allows for a total of 7kW of continuous power for one hour, or 4 kW total power continuous - at 750 lbs of weight. This just may work - if we 3D print a form frame for carbon fiber layup. 3D printing here may be the enabling technology.&lt;br /&gt;
&lt;br /&gt;
==Truck==&lt;br /&gt;
&lt;br /&gt;
The truck is a medium-size, hydraulic, 80 hp driven vehicle comparable to the Mercedes Unimog. https://en.wikipedia.org/wiki/Unimog  With a design top speed of 62 mph,  a weight of 6550 lb, and a hydraulic power take-off, the OSEmog could function as an agricultural tractor as well. The OSEmog is designed to accept a loader or various implements on the front or back. Using basic hydraulic circuits, the machine would have high and low gear, and speed cotrol via simple flow control valves.&lt;br /&gt;
&lt;br /&gt;
Fig. The OSEmog is a multipurpose truck for carryng loads or operating various implements. With off-the shelf parts, it is designed to be field serviceable, and the working hydraulic fluid can be grown - canola oil with additives.&lt;br /&gt;
&lt;br /&gt;
==Hydraulic and Electric Motors==&lt;br /&gt;
&lt;br /&gt;
Both the car have a choice of using hydraulic or electric drive. The advantages of hydraulics are low-cost, high torque, and simplicity of resulting drive design. Hydraulic motors cost only $10/hp, half that of electric motors - but a typical 40 hp hydraulic motor weighs about 50 lb http://opensourceecology.org/wiki/45.6_Cu_In_Hydraulic_Motor as opposed to about 350 lb https://inverterdrive.com/group/Motors-AC/TECA2-200L-4-Pole-B3-High-Efficiency-AC-Motor-200/ .  Typically electric motors are high speed and need to be geared down - whereas hydraulics can be used largely with direct drive. If high torque electric motors are used - these are more like $100/hp when the controller is included - making the drive system 10x as expensive for larger machines.  Electric motors are sensitive to moisture and dirt, while hydraulics are designed for dirty environments. &lt;br /&gt;
&lt;br /&gt;
We electric motors and generators - in solar electric power cubes - or in wind turbines. But the flexibility, power, and simplicity of hydraulics is a better choice for practical applications - especially when powered by hydrogen and transmitted by canola oil as the hydraulic fluid.&lt;br /&gt;
&lt;br /&gt;
The electric motor can also be 3D printed, making it fit with the OSE product ecology. &lt;br /&gt;
&lt;br /&gt;
Fig. A proprietary, 3D printed, 600W, 80% efficient electric motor. The equivalent is worthwhile to open-source.&lt;br /&gt;
&lt;br /&gt;
Electric motors can be both linear and rotary. In the linear form, they are known as solenoids - very useful devices that are used to make valves. For automation - we use dydraulic valves to control machines like the brick press - and solenoids are used wherever pneumatic or hydraulic controls are needed. This means any automated system - from the water control in aquaponics to the control of an industrial robot.&lt;br /&gt;
&lt;br /&gt;
The electric motor of interest ranges from a small 5W one to power a cordless drill - to the 50kW scale for use in the 50kW wind turbine.&lt;br /&gt;
&lt;br /&gt;
This brings us to the energy sector.&lt;br /&gt;
&lt;br /&gt;
=Energy Tools=&lt;br /&gt;
&lt;br /&gt;
The sun currently shines 10000 times more power to the earth than the entire civilization uses. The implications are profound: there is no such thing as an energy shortage. Energy scarcity is an imagined problem if we talk about actual availability of energy.&lt;br /&gt;
&lt;br /&gt;
We look at it as- it is a high priority to trap solar energy directly - by effective solar design of buildings (Homes and businesses spend about 50% of their energy on heating and cooling. )- and using photovoltaic energy (Solar Concentrator) to generate electricity locally, with wind (50kW Wind Turbine) wherever possible. For machines, the choice is to use hydrogen, charcoal, and compressed biogas. &lt;br /&gt;
&lt;br /&gt;
Hydrogen is by far the most efficient and clean when derived from water (as opposed to refining from oil and gas).  The process gives 0 pollution, and the product of hydrogen combustion is water. The OSE platform calls for provent internal combustion engines running on hydrogen as an immediately executable transition to a renewable energy future in transportation. Leading research institutes, such as the Rocky Mountain Institute (ref), promotes the hydrogen economy as the future, and hydrogen as a future energy source is not controversial if one assumes abundance of fuel feedstocks and distribution of energy production. Solar hydrogen can be produced anywhere, and wind hydrogen can be produced in most places around the world. We do not put such a high stake into batteries or supercapacitors when it comes to energy for cars, simply because chemical fuels are up to 140 times as energy dense. A typical energy density chart typically has chemical fuels off-the-charts good:&lt;br /&gt;
&lt;br /&gt;
Fig. Show specific energy density of storage media, with bats and caps, and chemical fuels, for perspective - https://en.wikipedia.org/wiki/Supercapacitor#/media/File:Supercapacitors-vs-batteries-chart.png. With supercapacitors having 100x less energy storage per weight than Lithium-Ion batteries, while costing 10x as much as ($2.85/kJ) as those batteries ($0.8/kJ), they are super-completely out of the question with today’s technology except for niche applications. Engines are .5kW/kg https://en.wikipedia.org/wiki/Power-to-weight_ratio#Engines  and Fuel (gas, diesel, methane) is 50MJ/kg and hydrogen is 140MJ/kg - or 50-140x more energy per weight than batteries. Given the environmental challenges of mining and recycling scarce metals, there is little case for battery-powered cars.&lt;br /&gt;
&lt;br /&gt;
That means that a non-battery car can lug around a higher percentage of payload (persons, cargo) rather than carrying around more car structure and batteries. &lt;br /&gt;
&lt;br /&gt;
For other purposes, biofuel pellets are desirable for heating fuel (after energy efficiency and solar thermal is maxed out) - such as by an aquaponic greenhouse with a black tubing heat exchanger.&lt;br /&gt;
&lt;br /&gt;
Biofuel pellets can be burned partly to release heat in winter - and if taken out of combustion after the volatile chemicals are burned off but before carbon burns to ash - then we have produced charcoal that can be used in a combustion engine. Thus, dual-fuel hydrogen/charcoal cars are in our view the transportation of the future. We are open to fuel cells entering the scene, and at $134/kW they are almost feasible.https://energy.gov/eere/fuelcells/fuel-cell-technologies-office-accomplishments-and-progress  They are too complex at this point for easy DIY production, so we may revisit this in 10 years if the technology becomes more accessible. Currently, fuel cells require exotic plastics and platinum, both of which are scarce resources. We are aiming for a sub $10k car which can be made with a standard internal combustion engine (ICE) running on hydrogen. Did you know that the first internal combustion automobile in the world ran on hydrogen in 1808? https://en.wikipedia.org/wiki/Fran%C3%A7ois_Isaac_de_Rivaz  Furthermore, ICEs are about 20% efficient - ICEs running on hydrogen are about 40% efficient. For comparison,  fuel cell vehicles are 50% efficient.http://environment.yale.edu/gillingham/hydrogenICE.pdf  Given that the efficiency gain of 25% of fuel cells over hydrogen ICEs comes at a 10x larger cost today, the case for pursuing hydrogen ICEs is much higher than the case for fuel cells. much cheaper H2ICE are seen by many experts as the means to provide a transition between emitting and non emitting transport and stationary system. https://pureenergycentre.com/hydrogen-engine/ &lt;br /&gt;
&lt;br /&gt;
Fig. The possible cost of a fuel cell car today for a 200kW sedan is $26k - and an overall minimum of about $75k. The open source hydrogen microcar is aimed at an under $10k cost and more than 100 mpg using widely available technology. (comparison of components and price, using ref 3 above)&lt;br /&gt;
&lt;br /&gt;
The answer already under our nose that is perhaps the most optimistic case for the energy revolution is solar power - at 0.015 cent per kilowatt-hour - demonstrated in 2016 by the Seed Eco-Home. http://opensourceecology.org/wiki/Hydrogen_Production  This is 4x cheaper than gas turbine electric generation  https://qz.com/135032/fuelcell-energy-fuel-cell-profit/  , and it allows for an equivalent 80 cent per gallon electricity cost for producing hydrogen.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
==The Power Cube==&lt;br /&gt;
&lt;br /&gt;
Our current Power Cube is a universal power unit that can power any of the large GVCS  machines, from cars to lathes to the brick press. The Power Cube is gasoline powered and has a 16 hp engine. We already ran this on charcoal gas - and as such - the same power cube can readily be used in dual-fuel operation - gasoline on the one hand, and charcoal on the other. Once we add the gas production infrastructure - the power cube can run on the hydrogen and biogas production from the House.  Because the pelletizer is part of the GVCS - we can make charcoal pellets from biomass pellets as a byproduct of space heating.  The concept of pellets is important - in that pellets are a flowable fuel. Meaning - that just like gasoline or tradition fuels - it can be stored in a tank and delivered as fuel as if it were a liquid - by using a small auger. This makes pellets a convenient fuel source, which unlike wood - can be used automatically in small machines.&lt;br /&gt;
&lt;br /&gt;
Moreover, the Power Cube can be run on solar energy, allowing for autonomous tractors and solar cars to enter. Solar power cubes are a good idea for shop power - where PV on the workshop roof feeds electric power cubes for hydraulic shop power. Power cubes can also be made very small - on the 1 kilowatt scale. They can also be stacked readily for higher power, so if we want a 160 hp bulldozer, we can do that based on our existing Power Cube.&lt;br /&gt;
&lt;br /&gt;
The Power Cube involves developing open source engines so that they enter the realm of lifetime design public technology. A universal version of an open source engine means that such an engine could be maintained and produced in a distributed fashion, bringing it closer to appropriate technology with a lifecycle that includes more reusability of parts.&lt;br /&gt;
&lt;br /&gt;
Fig. The Power cube and its different fuel sources - from gasoline, to charcoal, to compressed biogas, hydrogen, and electric.&lt;br /&gt;
&lt;br /&gt;
The large torque of hydraulics makes them very flexible for driving a wide range of machines. A small power cube, such as a 300W version running on a single solar panel, can be used to drive a 2000 lb MicroTrac as a practical, autonomous tractor.  The idea is that the machine would move very slowly - all day - on solar power. This is afforded by that fact that hydraulics have high torque at any speed - making this a perfect application of solar energy to autonomous, robotic tractor drive via a small microcontroller such as a $10 Pi Zero with Wireless.https://www.adafruit.com/product/3400   Thus, we can pull chicken tractors or pig tractors with a solar robotic tractor for a diversified agriculture operation.&lt;br /&gt;
&lt;br /&gt;
Fig. Infographic. Mega power cubes for 160 hp for a bulldozer, and a micro power cube for a solar grinder/pelletizer or chicken tractor.&lt;br /&gt;
&lt;br /&gt;
Autonomous animal tractors are another possible application of Power Cubes…&lt;br /&gt;
&lt;br /&gt;
Fig. The economic breakdown of an autonomous chicken tractor. PV panel + micro power cube at $500, plus the tracked drive for another $500 with open source hydraulic motors. The hydraulic motors (SME) are produced on the open source lathe (SME).&lt;br /&gt;
&lt;br /&gt;
==The Gasifier ==&lt;br /&gt;
&lt;br /&gt;
The OSE  gasifier is a device that converts charcoal into gas for fueling engines. Note that this gasifier uses charcoal that is produced as a byproduct of space heating. The gasifier is a metal container filled with charcoal, which upon being lit via in a small burn zone with an air inlet - burns and produces gas. This gas can be used as fuel in a regular internal combustion engine. The power of this lies in that with minimal modifications, a standard engine can be fueled by charcoal - which is derived from wood or other biomass.  This means that wherever plants grow - they provide a distributed and practical fuel source byond oil wars. https://www.cnn.com/2013/03/19/opinion/iraq-war-oil-juhasz/index.html  To produce charcoal, biomass is first pelletized. Burning pellets for space heat - and removing them from the burn before they turn to ash - produces charcoal pellets.&lt;br /&gt;
&lt;br /&gt;
Fig. Infographic. Space heating produces charcoal in the OSE ecosystem.  The Gasifier vaporizes charcoal, which is then burned in a standard engine. This process can be used to fuel cars - no engine modification required.&lt;br /&gt;
&lt;br /&gt;
The first reaction may be that if we turned plants into vehicle fuel - then we would destroy all of nature. That is not true, because there is plenty of biomass reserve that can be used to fuel the entire American car fleet, which uses about 60% http://needtoknow.nas.edu/energy/energy-use/transportation/  of all the energy in the transportation sector. Did you know that the largest single crop in the United States is lawn? There are 40 million acres of turf grass. http://scienceline.org/2011/07/lawns-vs-crops-in-the-continental-u-s/  What if we turned lawns into fuel crop, while increasing esthetics and reducing herbicides? Yields of grass are 4 dry tons per acre https://en.wikipedia.org/wiki/Biomass  - and if charcoal is produced at 25% efficiency - that is one ton of charcoal per acre - or 40 million tons of charcoal can be harvested from lawns alone, with no effect on food production, while increasing the ecological diversity of lawns. The average american uses 500 gallons per year of fuel.  https://www.treehugger.com/culture/pop-quiz-how-much-more-gas-do-americans-use.html  Lawns could thus provide ¼ of the entire car fleet fuel in the USA! (Charcoal is ¾ the energy content of gasoline by weight. At about 3 kg/gallon - 500 gallons is 1500 kg- about 1.5 metric tons - so 33M people could be supplied by fuel from lawns. If 95% of households have cars - https://photos.state.gov/libraries/cambodia/30486/Publications/everyone_in_america_own_a_car.pdf - and household is 2.6 - there are about 120M drivers in the USA. Thus  - ¼ of US drivers can be fueled by lawns.) This is at the crappy USA 23 miles per gallon - so increasing fuel efficiency to 100 mpg https://www.motherearthnews.com/green-transportation/green-vehicles/build-your-own-car-zm0z13amzmar with super-efficient micro-cars could mean that the entire US car fleet is supplied by fuel from grass. Efficiency and ecology - as opposed to battery technology with questionable environmental side effects and its centralization based on scarce resources - make the OSE platform converge on biomass and hydrogen as the fuels of choice. The OSE platform reserves the role of batteries only as a small part of vehicular power, not the backbone of the auto industry. &lt;br /&gt;
&lt;br /&gt;
The biomass route needs no technical invention to realize - today - and is also a carbon-neutral route. From the OSE perspective - hydrogen is clean (it produces water as the byproduct) but not better on ecological grounds (it does not contribute to biological ecology) - but it is much better on efficiency grounds.&lt;br /&gt;
&lt;br /&gt;
When discussing biofuels, it is important to point to the food-fuel-fiber integrated agroecology route as the preferred OSE route to agriculture. As opposed to genetic engineering to produce super-crops, the OSE platform favors ecological integration over genetic manipulation - so that we avoid creating super-problems at the same time. The ecological route means that we learn more about dealing with integrated ecosystems, not trying point solutions (genetic engineering) as a cure. When dealing with powerful technologies like genetic engineering, we must pay attention to unintended consequences. The current economic paradigm of profit maximization is not compatible with care in the use of genetic engineering. We favor increasing productivity by stacking yields of multiple crops that work harmoniously in a polyculture setting - with tree crops as a significant component. For us, the breakthrough work of Badgersett Research Farm is seminal in providing this leadership. They are developing perennial crops (hazelnuts and chestnuts) that could serve as a viable replacement for soybeans and corn. (ref).  Hazelnuts and chestnuts provide the same nutrition as their annual counterparts - but are perennial - and therefore do not contribute to the average 4 ton per acre annual soil erosion in the United States. (ref). Let me repeat that - the avarage topsoil loss in the United States - per acre - is 4 tons. What that means is that agricultural soils today are so depleted that they could not grow crops if it were not for the heavy inputs of fertilizers. The biological activity of commercial farmland is severely depleted (ref), not sustaining the soil food web of microbes that bring fertility back to the soil. (ref). Our proposition for perennial polyculture - is not new (ref on seminal works, Tree Crops, Regrarians, etc) - and it can produce food, fuel, and other materials.&lt;br /&gt;
&lt;br /&gt;
To improve the world, all you need to do is plant trees. Desertification still claims an additional ______________ square miles every year, and it would be good to reverse that.&lt;br /&gt;
&lt;br /&gt;
It takes less than 60x the land area to produce solar hydrogen compared to the land area required to grow biofuel crops.  Between biofuel (easy) and hydrogen (hard), humanity’s fuel needs can be met. Let’s look at numbers: we already said 300 gallons of fuel equivalent per acre (enough to fuel one car for a year at a fuel economy of 40 MPG https://www.google.com/search?q=average+miles+per+year+usa&amp;amp;oq=average+miles+per+year+usa&amp;amp;aqs=chrome..69i57j0l2.7415j0j7&amp;amp;client=ubuntu&amp;amp;sourceid=chrome&amp;amp;ie=UTF-8 ) fuel consumption -  roughly one gallon per day. If we apply this to hydrogen - 50kWhr of electricity is required to produce 1 kg of hydrogen, roughly one gallon gas equivalent. This can be obtained from a 9 kW PV array - running 6 hours per day - 54kWhr. The space required for a 9 kW array is 60 square meters if the panels are 15% efficient. An acre is 4000 square meters - so producing solar hydrogen requires 66 times less land area than growing the equivalent grass. Our materials cost for 9 kW of solar panels is under $9k. So one can obtain 20 years of hydrogen fuel for a PV investement cost of $17k.&lt;br /&gt;
&lt;br /&gt;
Fig. Home hydrogen production. The OSE open source goal is $9k for PV panels, $2k for storage, $2k for pump, $2k for plumbing, and $2k for the electrolyzer. That is $17k for a lifetime supply of hydrogen. Compare to gasoline - $1250/year on average. Payback time for  home fuel station is 14 years in the USA and 7 years in Europe. We intend to make hydrogen production a standard feature of the Seed Eco-Home.&lt;br /&gt;
&lt;br /&gt;
Add a paragraph about renewable energy plantations - perennial polycultures for fuel, food, fiber. &lt;br /&gt;
&lt;br /&gt;
Fig. Basic economic model for renewable energy plantations involves $x/acre in coppiced fuel, $1000/acre in nuts, and $2k/acre in sustainable chickens that fertilize the crop via autonomous chicken tractors.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
==Heat Exchanger==&lt;br /&gt;
&lt;br /&gt;
The heat exchanger is a device that takes heat from one medium and puts it into another. For example, in the Seed Eco-Home - we have a hydronic stove with heat exchanger which is used to heat water for heating the house.&lt;br /&gt;
&lt;br /&gt;
Fig. Hydronic stove with heat exchanger. A heat exchanger heats water, and if that water is boiled, it can be used to run a steam engine or turbine. Small steam engines have been used for shop power 100 years ago, and they can be used even more effectively today. You can get a working kit for $275 on Ebay.&lt;br /&gt;
&lt;br /&gt;
Simpler examples of the heat exchanger are the Hillbilly Heater. This device traps solar heat and puts it into water circulating through the black tubing. This energy is released through another coil in the aquaponic ponds, for example. A closed heat exchanger means that the water in the black tubing does not mix with the pond water. Or, this heat exchanger could be an open heat exchanger, where the water is heated and then used as hot water in a shower - so that a steady supply of new water is fed through the exchanger instead of just circulating - as in the pond heating case.&lt;br /&gt;
&lt;br /&gt;
Fig. The hillbilly heater can be used to heat ponds or to provide hot water for the house.&lt;br /&gt;
&lt;br /&gt;
==Modern Steam Engine==&lt;br /&gt;
&lt;br /&gt;
The modern steam engine is an engine that produces power from steam. The industrial economy was created by steam power. And steam turbines are the main way that power is generated today. &lt;br /&gt;
&lt;br /&gt;
A modern steam engine is a small engine that makes sense to build wherever space heating is involved. For example, a centrally heated building could be generating power at the same time as its being heated - if a heat engine with a generator is added to the system. Thus, we are piggy-backing on an existing power source, while using all the waste heat.&lt;br /&gt;
&lt;br /&gt;
Under 500 hp - or in any small scale installation - it is more effective to have a steam engine as the engine of choice. Above 500hp, it is more effective to use a steam turbine. Large power plant steam turbines reach 50% efficiency. https://en.wikipedia.org/wiki/Steam_turbine#Practical_turbine_efficiency &lt;br /&gt;
&lt;br /&gt;
A flame-fired or solar-powered heat exchanger can produce steam - for electricity generation. This makes sense for combined-heat-and-power systems. Most of today’s electricity is produced by water that is boiled in power plants to provide electricity via steam turbines. (ref) This can be done effectively on a scale of 500 or more horsepower - which is village scale, not home scale. For the smaller scale, a small steam engine can be used. For this reason, we have incorporated a modern steam engine into the GVCS - as a machine for producing electricity on top of a heat source. This could be done in our hydronic stove - where the water goes from the steam engine and then to house heating after some power has been extracted for electricity. It makes sense to convert the heat into high grade electricity - when the steam engine is connected to a generator.&lt;br /&gt;
&lt;br /&gt;
Fig. Hydronic stove with power generation.&lt;br /&gt;
&lt;br /&gt;
Did you know that the modern steam engine - a specific advanced version -  is more efficient than the internal combustion engine? The Cyclone engine is a high tech, high temperature steam engine made of stainless steel and exotic materials - with thermal efficiency over 30%. http://cyclonepower.com/ &lt;br /&gt;
&lt;br /&gt;
There is another steam engine that received a lot of attention on the internet but appears not to work well - the Green Steam Engine. We do not endorse the engine, as suggested by Tom Kimmel of Kimmel Steam Power  http://kimmelsteam.com/green-robertengine.html  - and you can read more in an old blog post. (http://opensourceecology.org/steam-meet-report/ . I have since contacted Mr. Greene for data on Feb 1, 2018, but I have not been presented with any data.)&lt;br /&gt;
&lt;br /&gt;
All together, the modern steam engine is valuable for household power, if the Power Cube is used for mobile power. Would would be the cost of a steam engine add-on to a household infrastructure? Small models of ¼ hp are available for under $300 in parts, (http://ebay.to/2EwmHWt ) and these are scalable readily to larger sizes. The current seed eco-home stove has sufficient power to run this engine, so only an additional pump would be required to feed water to this system.&lt;br /&gt;
&lt;br /&gt;
Integration of such a system would work well if pelletized biomass were used as fuel - and subsequently - charcoal would be produced for use in cars as a byproduct of household power generation. An interesting milestone would be an automated biomass energy system from an autonomous tractor-pelletizer - up to the production of charcoal as car fuel using gasifiers - all from one’s former lawn converted to bioenergy crop.  In such case, nickel iron batteries may be desirable in so far as excess energy storage from daytime solar power.&lt;br /&gt;
&lt;br /&gt;
Fig. The energy product ecology of the Seed Eco-Home includes solar hydrogen, biogas for cooking, and production of car fuel from the lawn.&lt;br /&gt;
&lt;br /&gt;
==Solar Concentrator==&lt;br /&gt;
&lt;br /&gt;
The modern steam engine equation becomes much more exciting when solar concentration is used. Using 30% efficient, modern steam engines, proven linear solar concentrators, and a night-time storage system based on large, insulated propane tanks with hot water - it is possible to produce an off-grid energy system with $100/kWhr energy storage costs - 4x cheaper than lithium ion batteries. https://en.wikipedia.org/wiki/Lithium-ion_battery  A breakthrough company - Terrajoule - has already demonstrated this. Then the question becomes - if this has already been shown in the first prototype of Terrajoule, why isn’t everyone doing this when the technology is all proven? One cannot beat the simplicity of water and solar heat as the ultimate storage medium. &lt;br /&gt;
&lt;br /&gt;
What can water really do? When water is heated but not allowed to expand, it turns to what is known as saturated water. A saturated liquid is a liquid whose temperature and pressure are such that any decrease in pressure without change in temperature causes it to boil. In other words, if a tank was not holding the water at pressure - that water would turn into steam.&lt;br /&gt;
&lt;br /&gt;
Just how much energy can that water store at a medium pressure? A lot. Looking at the total heat content of water that would otherwise turn to steam, but is held under pressure at 18 atmospheres (250 PSI) in a tank instead http://opensourceecology.org/wiki/Saturated_Water  - we see that each kilogram of such saturated water holds about ¼ kWhr of energy. That means that a 10,000 gallon propane tank can store about 4MWhr of energy! We can extract that energy with a modern steam engine, where steam engines from the 1950s got to about 30% efficiency. https://en.wikipedia.org/wiki/Uniflow_steam_engine   After all the losses, we we would have 300kWhrs of electricity when the modern steam engine runs a generator.&lt;br /&gt;
&lt;br /&gt;
We can scale that down to a residential system - just a 1000 gallon propane tank - and 30kWhrs of electricity produced.&lt;br /&gt;
&lt;br /&gt;
Fig. Cost and energy of a home-scale solar energy storage system using water and modern steam power. From energy content of 400kWhrs to 30kW hours of electricity is quite doable using proven technologies, at ¼ the cost of battery storage.&lt;br /&gt;
&lt;br /&gt;
==Nickel Iron Battery==&lt;br /&gt;
&lt;br /&gt;
Nickel-Iron Batteries are long-life batteries that have a track record of lasting 50 or more years. Unlike other batteries, these can be discharged fully without decreasing their lifetime. These are chosen for the Global Village Construction Set specifically for their long life - and becuase nickel and iron are not scarce resources. While heavier and 2x more expensive than lithium ion batteries, (Read an intereresting pro-con discussion - http://opensourceecology.org/wiki/Nickel_Iron_vs_Lithium_Ion_Battery_from_Tesla_Motors ) they make up by their long lifetime, and lend themselves to decentralized production. New developments are in progress, ( https://news.stanford.edu/news/2012/june/ultrafast-edison-battery-062612.html )  though OSE does not rely on new developments for feasibility given that OSE internalizes social and environmental aspects for true cost accounting. The cost is currently high because production volume is low - only 2 US manufacturers. Based on a nickel price of $6/lb and iron at 25 cents/lb, and a weight of 100 lb for 1kWhr - and a 20% content of nickel in nickel iron batteries https://www.solarpaneltalk.com/forum/off-grid-solar/batteries-energy-storage/ni/7052-how-much-nickel-is-really-in-a-ni ckel-iron-ni-fe-battery - the base materials cost of materials in Nickel Iron batteries appears to be $150/kWhr. That is similar to lead acid batteries and ½ of lithium ion costs - but if the lifetime of these batteries is really 50 years, then they are 5-10x cheaper than other batteries based on lifetime.&lt;br /&gt;
&lt;br /&gt;
According to recent research: https://link.springer.com/content/pdf/10.1007/s10800-015-0911-3.pdf &lt;br /&gt;
&lt;br /&gt;
There are many reasons favouring the use of NiFe cells as cost-effective solutions to store grid-scale amounts of energy, such as low cost of raw materials, environmental friendliness, electrical abuse tolerance, long life (in the order of thousands cycles of charge and discharge) and compatibility with photovoltaics (PVs). Due to the nature of the heavy metals involved in its construction this technology is suitable for stationary low gravimetric energy applications (30–50 Wh kg-1 ). As a consequence, there are good reasons to foresee a large scale utilization of this technology. Due to their outstanding safety properties (zero flammability, fail safe, no over/ under charge), low cost and long lifetime, we anticipate that they will receive widespread public acceptance for customer-connected energy storage.&lt;br /&gt;
&lt;br /&gt;
It is our hope that the nickel iron battery would be only a small fraction of electrical power storage needs in the future - such as replacing 5-year lifetime starter batteries in vehicles. For night time electricity, it would be useful for warmer regions to use solar concentrator saturated water storage - as one possibility - or solar hydrogen as another.&lt;br /&gt;
&lt;br /&gt;
In colder areas, biomass is typically available as an abundant energy crop - where PV may not be adequate if there are weeks without sun. The exact mix of solar concentrator electric, PV, wind, charcoal, biomass, biogas, and hydrogen is to be determined at Factor e Farm as we measure the value of all these systems side by side. The main requirement for OSE is true service to humanity, environmental regeneration, and freedom from resource conflicts.&lt;br /&gt;
&lt;br /&gt;
==50 kW Wind Turbine==&lt;br /&gt;
&lt;br /&gt;
A wind turbine converts a renewable form of energy - wind - into electricity. It provides a good backup to PV electricity, as wind typically blows when the sun is not out.&lt;br /&gt;
&lt;br /&gt;
We propose a vertical axis wind turbine for the initial OSE version based on integration with hydraulics and the Universal Rotor.  A simple system can consist of a pole mounted 40 hp hydraulic motor ($400), serving as a pump - which transfers fluid power to an on-the-ground hydraulic motor ($300) + 24 kW generator ($1000). The power generator related costs are ~ $2000 here, and the rest is the tower and structure. With $6k spent on the materials for this wind turbine, this would be $250/installed kW in materials costs - with installation being 15% on top of this http://www.esru.strath.ac.uk/EandE/Web_sites/14-15/XL_Monopiles/cost.html  - a very attractive package in a sweet spot of cost for readily-available components. This is compared to $1590/kW standard costs of large scale wind installations. https://www.awea.org/falling-wind-energy-costs &lt;br /&gt;
&lt;br /&gt;
The OSE design features a generator that is mounted on the ground, with only the hydraulic motor on top of the tower. This facilitates maintenance considerably. The savings is due in part to the great simplification of the nacelle - in the OSE case, the vertical axis design doesn’t have a yaw mechanism - it’s just a hydraulic motor that accepts wind from any direction. These turbines are not as efficient in terms of wind capture as they are lower to the ground - but the low capital + maintenance costs make up for the lower efficiency. Because they can be packed more tightly in the same area, however - VAWT wind farms can actually produce 10x the energy of a propeller-type wind farm. https://en.wikipedia.org/wiki/Vertical_axis_wind_turbine#Advantages  They also self-regulate their speed, so they do not need a braking meachanism for overwind conditions.&lt;br /&gt;
&lt;br /&gt;
Fig. OSE VAWT concept. Simplification of design include ground-mounted generator, yawless rotor, screw pile foundation https://en.wikipedia.org/wiki/Screw_piles#Modern_Use_and_Benefits  , and braking via the hydraulic motor as the overspeed protection. The wind turbine module is designed for 24 kW, and it includes the Electric Motor/generator, Universal Rotor, Hydraulic Motor, Power Cube, and Universal Power Supply for managing power.&lt;br /&gt;
&lt;br /&gt;
8. Universal Power Supply&lt;br /&gt;
The Universal Power Supply (UPS) is the last of the energy machines. It is a universal device for powering large electronic machines - induction furnaces, welders, plasma cutters, laser cutters - and for controlling power delivery and transmission to homes or electric cars. It is also used for charging. The UPS has feedback such that it would know when batteries are full, or for optimizing the power transfer into a load of metal that is melted with the induction furnace. &lt;br /&gt;
&lt;br /&gt;
The Universal Power Supply in general  converts AC and DC into voltages and currents of any amplitude and frequency. The UPS is scalable from a few watts to 20kW based on the same design of modules.  The Universal Power Supply can also be used to condition power from the wind turbine or PV system and pump it into the grid. It can also be used as an inverter to convert DC to AC, or it can be used to control the speed of an electric car. It can also be used to step power up to high voltage for power transmission over longer distances, such as up to the 69,000 volts for rural power lines. &lt;br /&gt;
&lt;br /&gt;
As with the mechanical machines, the Universal Power Supply is based on modular design, such that we can arrive at a Construction Set. Just like power units, wheels, shafts, hydraulic motors, control valves, and frames can create any mechanical industrial machine, so can a small number of modules provide just about any electrical power function in the Universal Power Supply. These modules are mainly: a microcontroller, a current measurement device, a transistor, wires, laminated cores, ferrite beads,  diodes, optocouplers, resistors, capacitors, and inductors - plus a few mechanical components such as plugs, cases, cooling systems. With advanced transistors that now cost $1 per kW of power handling, large power electronic devices can be built on the cheap if open source knowhow is available.&lt;br /&gt;
&lt;br /&gt;
Wires and metal cores themselves produce a wide range of devices: inductors, transformers, relays, solenoids, switches for large currents, electric motors, spark generators, electromagnets, and other devices. &lt;br /&gt;
&lt;br /&gt;
Lasers, charge controllers, inverters, welders, induction furnaces, plasma cutters, oxyhydrogen generator power supply, and motor controllers are all functions that can be generated with the Universal Power Supply. These are all based upon currents and voltages at different frequencies and amplitudes that perform radically different functions. This has to do with the nature of electricity - jus like a few atom types (100 or so) make up millions of different substances that are all around us - so can electricity be manipulated to perform a wide array of functions. Any of the above devices consist of a microcontroller and a power transistor - along with some resistors, capacitors, and inductors. The microcontroller could be an Ardduino or a Rasperry Pi - which now cost as little as $5 for these small computers running with a 700MHz cpu. This CPU - via software - can produce a voltage of any amplitude and frequency using transistors. In other words - a ‘brain’ - the CPU - can massage electrons so they maifest at any voltage or frequency - by using transistors - or devices where a small signal from a CPU controls a large voltage. Essentially - a transistor is a switch - which is activated by a small signal.&lt;br /&gt;
&lt;br /&gt;
For example - taking DC voltage - one can make it pulsed and appear as an oscillating sine wave. This is an inverter for household power - which can for example take electricity from PV cells and convert that into household current. Or - this same inverter can be pulsed much faster to create a 30kHz voltage used in an induction furnace. And regulation can happen - such as an induction furnace delivering power most effectively to the molten charge - when the same microcontroller can measure the voltage, and change the frequency of the applied voltage to pump power more effectively into the melt. &lt;br /&gt;
&lt;br /&gt;
This is all possible because superfast microcontrollers, and high power handling transistors - can all be purchased now for a few dollars.&lt;br /&gt;
&lt;br /&gt;
Energy Summary&lt;br /&gt;
&lt;br /&gt;
Combining biomass, charcoal, biogas, wind power, the solar concentrator,  steam electricity, hydrogen, PV - and the electronic controls of the Universal Power Supply -  makes for a resilient power infrastructure without necessitating resource conflicts.&lt;br /&gt;
&lt;br /&gt;
=Open Source Microfactory=&lt;br /&gt;
&lt;br /&gt;
The Open Source Microfactory (OSM) is the crown jewel of the Global Village Construction. It is the part that allows for GVCS self-replication - in that the Open Source Microfactory allows for the production of all the  GVCS tools - including the Microfactory itself..&lt;br /&gt;
&lt;br /&gt;
The Open Source Microfactory is broken into 2 main parts: precision CNC tools, and metal production tools. The CNC tools - which stands for Computer Numerical Control - are automated machines that can be programmed to build things - from small parts, to engines, and everything in between. The metal production tools allow for the production of virgin steels from scrap. The steel that can be produced with the GVCS metal tools thus allows for the creation of advanced civilization - wherever there is access to scrap steel. Scrap steel is abundant, and so it iron ore from which steel is made. Iron is the 4th most abundant element in the earth’s crust - after oxygen, silicon, and aluminum. https://en.wikipedia.org/wiki/Abundance_of_elements_in_Earth%27s_crust &lt;br /&gt;
&lt;br /&gt;
What if there is no scrap steel available? We can go to aluminum - which is even more abundant in terms of the crust’s composition. Aluminum is found in common clay. Clay is aluminosilicate, from which aluminum can be extracted. Because Aluminum is so abundant - the GVCS goes so far as the extraction of aluminum from clay. This is intended to break through any notions of scarcity in today’s civilization.  Clay is abundant, and it’s an essential part of the GVCS: compressed earth blocks, soil for growing food, clay for 3D printed pots and cookware - in addition to the production of aluminum metal.  &lt;br /&gt;
&lt;br /&gt;
Fortunately - silicon is even more abundant. We get solar cells for producing electricity from silicon - a core technology for the GVCS such as in the Seed Eco-Home. In less than the time it takes to read this paragraph, the sun will have provided as much energy to Earth as used by all of human civilisation in one day. Thus silicon solar cells are important. And silicon is used to make semiconductors - so silicon creates the computer age.&lt;br /&gt;
&lt;br /&gt;
With the Open Source Microfactory - we thus aim to show that literally, modern civilization may be created -  from dirt and twigs. This can happen on any parcel of land - as solar cells can easily produce about 500kW of energy - from an acre. So a facility such as the OSE headquarters can produce all the technology required to produce an advanced civilization. For example, 500kW of solar energy - or 3MWhrs per 6 hours of daylight - can produce 200 kg of aluminum per day. Aluminum requires 15 kWhr per kilogram to smelt. (http://wordpress.mrreid.org/2011/07/15/electricity-consumption-in-the-production-of-aluminium/ . This one says ,05 GJ/kg - http://wordpress.mrreid.org/2011/07/15/electricity-consumption-in-the-production-of-aluminium/ )Aluminum is energy intensive - but its production may one day be improved for more environmentally-sound production - as can any other process by internalizing environmental costs.  https://www.sciencedirect.com/science/article/pii/S0360544207001065#! &lt;br /&gt;
&lt;br /&gt;
This shows how energy intensive aluminum production is - but its 3x better weight to strength ratio compared to steel makes it a desirable product. With the proposes 200kW solar microfactory - we can produce 80 kg of aluminum per day. That’s not a lot - but acceptable as a proof of concept for an appliance-size machine.&lt;br /&gt;
&lt;br /&gt;
Aluminium is the most abundant metallic element in the Earth’s crust (about 8%) and the&lt;br /&gt;
second most widely used metal next to steel. The aluminum production process involves taking ordinary clays such as abundant kaolin clay - and leaching out alumina with hydrochloric acid to produce Al203, which is subsequently turned to Aluminum via electrolysis at a cost of 15 kWhr per kg of aluminum produced. For reference in terms of energy requirements - this is like converting one gallon of gasoline to one kg of aluminum. That’s a lot of energy. But the main point here is that this can be done anywhere where there is soil - clay for making aluminum is an abundant feedstock.&lt;br /&gt;
&lt;br /&gt;
If we talk about the carbon dioxide emissions - whether from aluminum or steel production - the way we propose to make it sustainable is to make the CO2 recyclable. If the carbon involved in the reactions for producing metals - or for that matter any other product - comes from charcoal derived from biomass - then the industrial process is regenerative as the plants that were used to produce the charcoal took the carbon out of the atmosphere in the first place. Thus, a sustainable industry is possible  when civilization evolves to using charcoal  instead of fossil fuels. &lt;br /&gt;
&lt;br /&gt;
However, it should be stated that CO2 in the long run may be more advantageous for ecology - even from fossil fuels - if that CO2 yields more plant growth. While many people see CO2 per say as a global warming problem - it is also possible that the CO2 will make the earth more green. Nobody knows what will happen at this point - we can only speculate as to the long term effects of increasing CO2 in the atmosphere. &lt;br /&gt;
&lt;br /&gt;
The open source microfactory is intended to produce an entire technosphere from local resources, pushing the limits of what can be done:&lt;br /&gt;
&lt;br /&gt;
Fig. Open Source Microfactory cyclic material flows can be based on local resources. Metals, bioplastics, ceramics, PV cells, concrete, carbon, hydrogen, glass, rubber, fuels, food, construction materials, and many other chemicals can be produced from local abundance.&lt;br /&gt;
&lt;br /&gt;
If it is indeed that PV cells can be made from local sand, and aluminum from clay - and everything else as noted - then we have truly stepped into a world of post-scarcity. At the point where material production is guaranteed, it may be possible for people to evolve full time - without being held back by mere survival. That is the essence of society that OSE intends to create - one in which material needs are not in the way of human evolution.&lt;br /&gt;
&lt;br /&gt;
For any other processes of industry - the Open Source Microfactory can provide. If you can make buildings, glass, metal, and plastics + other materials - you can build anything. Advanced processes such as chemical plants or semiconductor fabs - are nothing but buildings, metal vessels, motors, vacuum pumps, and a few other basics - and from there spews out any product - in a nutshell. This does not even involve the nanotech of molecular manipulation - where it is deemed that in the future we will be able to synthesize substances by moving atoms directly - without regard for chemical reactivity as we know it today. Yet we do not invoke the Technological Singularity as a prerequisite for meeting all human needs.&lt;br /&gt;
&lt;br /&gt;
Let’s move to the specific tools in the Open Source Microfactory:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
And &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Fig. Tools of the Open Source Microfactory. They include everything needed to produce precision metal parts starting from scrap metals, glass, bioplastics, and even semiconductors for solar cells. &lt;br /&gt;
&lt;br /&gt;
==Universal Axis==&lt;br /&gt;
&lt;br /&gt;
Six of the Open Source Microfactory tools are based on the Universal Axis. The Universal Axis is a modular, and scalable CNC axis which can be used to create cartesian CNC machines. The core of the axis design is belt drive and linear motion rods where carriages are pulled on the rods. The system is scalable to any size and number of axes, including rotary axes. The system uses a combination of 3D printed parts, metal plates, and belt-driven shafts. Applications include 3D printers, CNC torch tables, heavy duty CNC machines, and many other production machines.&lt;br /&gt;
&lt;br /&gt;
We intend to use the 5/16”, 1”, and 2” versions for 3D printers, CNC torch tables, and heavy duty CNC machines - which are among the key machines that can be built with the system - though a variant of any size and shape can be designed.&lt;br /&gt;
&lt;br /&gt;
Fig. The universal axis comes in 5/16”, 1”, and 2” variations, and is based on belt drive, though a screw and nut system can also be used as a drive. Various tool heads can be attached. Non-contact tool heads are attached magnetically, such as the laser cutter and 3D printer. Rotary attachments can even be used for 3D scanning or indexing.&lt;br /&gt;
&lt;br /&gt;
For heavy duty applications, the plastic plates may be reinforced with steel plates - making a steel-plastic composite that has the required strength - while being easy to produce because the complex geometry is 3D printed. The metal plates themselves can be CNC cut using the CNC torch table. This allows for the lowest cost route - the 2” bushings capable of 8000 lb force on these axes currently cost only $9.41 at McMaster Carr.&lt;br /&gt;
&lt;br /&gt;
Fig. Metal-plastic Universal Axis System.&lt;br /&gt;
&lt;br /&gt;
The power of the universal axis lies in its flexibility. The same design of the drive system can be used to make an unlimited range of fabrication machines, putting the manufacturing process completely in the hands of anyone - without high barriers to entry. This is aimed at the Open Source Microfactory in every town, where our goal is to distribute at least 10,000 of these open source microfactories around the world, each generating at least $100,000 of net revenue per year. Once production returns to communities, we expect that taxes will go down as communities once again become responsible for their own prosperity.&lt;br /&gt;
&lt;br /&gt;
==The 3D Printer, Bioplastic Extruder, 3D Scanner==&lt;br /&gt;
&lt;br /&gt;
The 3D printer is a machine with diverse applications. Essentially, the technosphere is made from plastics, ceramics, and metals. 3D printers can print with all of these, and are as such ubiquitously applicable to manufacturing of all sorts. Currently, it is easy to print with all kind of plastic, including rubber for printing tires and polycarbonate for printing glazing. It is likewise easy to print ceramics - by printing clay and then baking it. Here we can produce ceramic cookware or clay parts such as insulators or building bricks. If the clay contains a large fraction of glass or metal - then upon kilning - 3D printed glass and metal objects can be printed as well. Metal printing can also happen via a MIG or TIG welder as the working toolhead - where large metal structures can be printed additively like this. If we go a step up to lasers - we can do selective laser sintering of any kind of powder - from plastic, to ceramic, to metal. Extremely strong, precise metal parts can be created this way - such that for example the rocket engine for Elon Musks’s SpaceX rockets has been 3D printed.&lt;br /&gt;
&lt;br /&gt;
Fig. Different applications of 3D printing: plastic, rubber, glass, metal, ceramic, and housing.&lt;br /&gt;
&lt;br /&gt;
Carbon fiber or metal fibers can also be embedded in plastic 3D prints to make the parts as strong as aluminum. 3D printing can also print ceramic molds which can then be used for casting directly into these molds - using either molten metal from an induction furnace or a MIG weld right into the metal form.&lt;br /&gt;
&lt;br /&gt;
Fig. Apparatus for automated metal casting using 3D printing of molds + induction heating of melt to fill the molds.&lt;br /&gt;
&lt;br /&gt;
Currently - open source printing includes  plastic + rubber 3D printing, welder 3D printing, clay printing for ceramics, clay-metal 3D printing for metals, selective laser sintering of plastics, and 3D priting of concrete or clay buildings. With a little bit of work,  the full printing with metal or glass using selective laser sintering can be developed by using off-the-shelf technologies. An 80W laser tube like in the Laser Cutter + shielding gas allows for selective laser sintering of off-shelf metal powders. http://opensourceecology.org/wiki/Metal_Selective_Layer_Sintering#Literature &lt;br /&gt;
&lt;br /&gt;
Fig. If metal powder is available (it is, such as iron at $1/lb) - then we can use a laser to fuse a powder bed to complex 3D objcts that cannot be produced in any other way.&lt;br /&gt;
&lt;br /&gt;
The world of 3D printing is in its infancy - and this is definitely worth refining to achieve full 3D printability in any material. Perfecting all of the above 3D printing can go far towards local production of just about anything.&lt;br /&gt;
&lt;br /&gt;
==Bioplastic Extruder==&lt;br /&gt;
&lt;br /&gt;
The Bioplastic Extruder is part of a system that enables the production of biodegradeable bioplastics from natural feedstocks such as cellulose or sugars. The system includes 3D printing filament production as well as direct extrusion of useful parts.  &lt;br /&gt;
&lt;br /&gt;
Four main aspects are involved in the Bioplastic Extruder System. First, a bioplastic reactor is used to make bioplastic from abundant biological feedstocks such as cellulose, sugar, or starch. Second - once the plastic is produced - or is available from the waste stream - it can be extruded with the Bioplastic Extruder to make 3D printing filament. Third, the 3D printing filament is then used directly in 3D printers to make useful objects. Fourth, other useful products can be made with the extruder: plastic lumber, which can be made from recycled plastic and sawdust. This could be a great way to recycle plastics into durable construction materials. Other useful profiles - such as tubing and glazing panels - can also be produced with the bioplastic extruder. Thus, the bioplastic extruder per se can be used for 2 main purposes: making 3D printing filament as an intermiediate feedstock for 3D printers - or extruding useful products directly.&lt;br /&gt;
&lt;br /&gt;
Fig. The bioplastic production system of the GVCS consists of bioplastic synthesis followed by extrusion to produce 3D printing filament, tubing, sheets, or plastic lumber. 3D printing filament can be used for 3D printing. Thermoplastic elastomers - or rubber - can also be printed.&lt;br /&gt;
&lt;br /&gt;
There are 3 types of bioplastics - those derived from: (1) petroleum and biodegradeable; (2) biomass and biodegradeable; and (3) biomass and non-biodegradeable. OSE is most interested in bio-based, biodegradeable bioplastics, as the feedstocks are most widely available and can be produced ecologically anywhere in the world. &lt;br /&gt;
&lt;br /&gt;
The OSE bioplastic system allows for local recycling such that the plastic never ends up in the landfill - but is either reused or recycled. By eliminating plastic waste and turning it into valuable products, wealth can be multiplied. Also, we can clean up the environment by reusing plastics - which can otherwise persist in the environment for 1000 years. Such recycling also reduces the need for petroleum - the typical feedstock of plastics.&lt;br /&gt;
&lt;br /&gt;
Bioplastics derived from biomass that are non-biodegradeable can be produced from petroleum substitutes. Petroleum can be replaced with charcoal. As such, any plastic typically derived from petroleum can also be produced from renewable, plant-derived charcoal. In the OSE system, plant matter is pelletized, then burned partially for space heating or process heat - with the byproduct being the important charcoal feedstock. If one is interested in replacing petroleum-derived chemicals - charcoal is first burned in a gasifier to produce CO and H2 - just as the gasifier fuels regular engines with CO and H2 - a combustible mixture. Instead of being burned in an engine as a renewable fuel, these molecules can combine under heat and pressure and an iron catalyst to produce long hydrocarbon chains and water. The long chains are alkanes - the typical long-chain molecules of -[CH2]- found in petroleum. This conversion process is known as Fischer-Tropsch synthesis, and is important from the abundance mindset - in that all products than now come from coal and petroleum can be made more ecologically - from plants. https://en.wikipedia.org/wiki/Fischer%E2%80%93Tropsch_process  &lt;br /&gt;
&lt;br /&gt;
Fig. The circular economy of OSE is based on wood - to make charcoal, paper, bioplastic, rubber, and fuel.&lt;br /&gt;
&lt;br /&gt;
Cellulose acetate is a bioplastic that is easily made from the most abundant organic polymer in the world - cellulose. It can be made readily from trees. Did you know that wood fibers can be converted to this bioplastic by reacting these fibers - with glacial acetic acid? The product is 3D&lt;br /&gt;
&lt;br /&gt;
printable.http://www.designforcraft.com/new-materials-for-3d-printing-cellulose-acetate/  You can make windows with it.http://nvlpubs.nist.gov/nistpubs/jres/19/jresv19n4p367_A1b.pdf  Instead of trees, one can use any source of cellulose - paper, cotton, straw, or other cellulose materials. &lt;br /&gt;
&lt;br /&gt;
Straw and wood are thus very important in the overall product ecology for making fuel pellets, insulation for the Seed Eco-Home (with borax), strawboard, charcoal, paper,  steel (charcoal with iron ore), and bioplastics.&lt;br /&gt;
&lt;br /&gt;
Polylactic Acid, or PLA, is the most popular bioplastic used in 3D printing. It can be derived from bacterial fermentation of sugar - and is thus an accessible technology within the GVCS.&lt;br /&gt;
&lt;br /&gt;
Polyhydroxyalkanoate (PHA) or polyhydroxybutyrate (PHB) bioplastic polyesters are considered the best candidates to replace the current petroleum-based plastics due to their durability in use and wide spectrum of properties. https://www.intechopen.com/books/biotechnology-of-biopolymers/conversion-of-biomass-into-bioplastics-and-their-potential-environmental-impacts  They are made by bacteria from sugar or starch at an efficiency of up to 80% of bacterial cell mass.https://www.intechopen.com/books/biotechnology-of-biopolymers/conversion-of-biomass-into-bioplastics-and-their-potential-environmental-impacts  Some PHAs are elastomers. Thus - it is realistic to include rubber production for tires - from sugar or starch - within the industrial ecology of the GVCS. Unlike latex resin from dandelion roots - which can be used to produce thermoset plastics - PHA rubber is thermoplastic, so it can be recycled easily. Both PHA rubber and dandelion root rubber can be grown anywhere - thus removing the strategic importance of tropical rubber tree plantations. It appears that PHA rubber is more viable from the decentralization perspective. Wood, broken with acid to simpler sugars - can also be used a feedstock for PHA - thus making PHA rubber production possible anywhere in the world. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4964529/   However, woody crop can compete with food crops - so we once again emphasize perennial polycultures as ways to produce food, fuel, and fiber. With perennials, it is also easier to use degraded lands, which can be regenerated back to fertility and health when annual crops are removed from the equation.&lt;br /&gt;
&lt;br /&gt;
In addition to sugar and cellulose, starch from common sources such as potatoes or corn can be polymerized readily in the kitchen. For example, mixing vinegar and glycerine with the starch makes a bioplastic.http://opensourceecology.org/wiki/Starch_Bioplastic   This is the easiest route  that can be used for 3D printing&lt;br /&gt;
&lt;br /&gt;
The bioplastic extruder has 2 main functions: one is to perform extrusions directly - or to produce intermediate 3D printer filament which is then used to 3D print final objects. For the latter, we are currently building upon two open source projects working on plastic extruders: the Lyman Filament Extruder,http://opensourceecology.org/wiki/Lyman_Filament_Extruder  and the Thunderhead Filament Extruder from Tech For Trade.http://opensourceecology.org/wiki/TechforTrade  These are simple versions of plastic extruders - which if scaled up and made more robust - can produce not only 3D printing filament, but larger extrusions.&lt;br /&gt;
&lt;br /&gt;
==3D Scanner==&lt;br /&gt;
&lt;br /&gt;
The 3D scanner allows for scanning of 3D objects to produce Computer Aided Design (CAD) models for reverse engineering. This is very useful - as we can take existing parts and digitize them for use as editable CAD models. A single camera can be used for photogrammetry, which is a computational technique for converting a set of pictures of an object taken from multiple angles into a 3D object.http://opensourceecology.org/wiki/Open_Source_Photogrammetry There is a number of open source programs that can do this. A 3D digital object can also be generated using multiple cameras, laser beams, or other light sources reflected from an object. As the simplest route, OSE  will build on existing work to develop the toolchain and procedure for photogrammetry - as that requires no hardware outside of a simple camera and a computer to process the images. If markers are used on objects, accurate CAD can be generated with proper dimensions. &lt;br /&gt;
&lt;br /&gt;
It gets more interesting: we can 3D scan internal features, too. This is known as industrial Computed Tomography (CAT) - essentially - a CAT scan for metal objects. By using an x-ray or gamma ray source - and then photographing an image - we can build a low-cost DIY CAT scanner.https://www.youtube.com/watch?time_continue=25&amp;amp;v=hF3V-GHiJ78  http://www.tricorderproject.org/blog/tag/openct/  Combined with an open source code base for image processing  from CERN, 3D industrial tomography scans can be obtained.https://home.cern/cern-people/updates/2016/09/new-open-source-medical-imaging-tools  &lt;br /&gt;
&lt;br /&gt;
==CNC Circuit Mill + Small Laser Cutter==&lt;br /&gt;
&lt;br /&gt;
We have already prototyped a circuit mill - the D3D CNC Circuit Mill.http://opensourceecology.org/wiki/D3D_CNC_Circuit_Mill  This shows a great example of the Unversal CNC axis modularity - where we have used the same motion system as in the 3D printer - but now strengthened the motion system by doubling the x axis to hold a small router. While the 3D printer is a non-contact manufacturing method - the circuit mill requires that the axes withstand contact forces of the milling operation. The strong, steel space frame of the D3D platform can handle these forces.&lt;br /&gt;
&lt;br /&gt;
Furthermore, other tool heads can be used on the Universal Axis. One useful example is a small 4W laser cutter, which cut up to ¼” plywood for prototyping purposes.&lt;br /&gt;
&lt;br /&gt;
Fig. The OSE CNC circuit mill and example circuits produced. The Router Tool Head is one of many tool heads that can be used on the Universal Axis system. A small laser is another, and can be retrofitted readily. The laser cutter toolhead allows for cutting cardboard for rapid prototyping. (4-picture - mill+product, laser+product)&lt;br /&gt;
&lt;br /&gt;
Prototyping with a laser cutter is important to the GVCS because the laser cutter can simulate the cutting that is typically done with a CNC torch table. Just like the CNC torch table typically cuts ½” thick flat parts out of sheet steel - the small laser cutter can cut parts out of paper stock. These parts can then be glued or fit together - just like the CNC-torch-cut metal parts are welded to make real-life 3D machines such as the CEB Press.&lt;br /&gt;
&lt;br /&gt;
Fig. Flat metal is used to generate 3D objects by welding. We thus use 2D cutting to create 3D objects.&lt;br /&gt;
&lt;br /&gt;
An open source project for a larger laser cutter - the 100W Lasersaur - is already well-developed. We can use this platform to build upon as well, to reduce cost from its current $7k to something more on the scale of $3k for a large format laser cutter. The Universal Axis could be applied here, such that only the laser system ($2000) remains as a significant cost - and the rest of the system is ($1000). This would be another great application of the Universal Axis to show its flexibility.&lt;br /&gt;
&lt;br /&gt;
Another useful example of a practical tool-head is a ceramic 3D printer head - which is an extruder for clay materials that can be fired to make functional ceramics. Examples of very useful ceramics are insulators and pottery - especially stovetop cookware made of flameware clay - which can replace commercial cookware and provide artistry in the open source Seed Eco-Home kitchen.&lt;br /&gt;
&lt;br /&gt;
Fig. The ceramic print head allows for the production of practical objects such as pots and pans for cooking, bringing artistry back into the kitchen.&lt;br /&gt;
&lt;br /&gt;
Collaborative Prototyping + Model Kits + Product Ideas + The Open Source Everything Store&lt;br /&gt;
&lt;br /&gt;
With access to the OSE Developer Kit - 3D printer, CNC Circuit Mill, and Laser Cutter - all as different tool heads on the same Universal Axis system - collaborators access a powerful capacity to prototype the larger machines of OSE. Using these tools, accurate scale models can be built. This can extend the collaboration capacity on OSE machine development significantly. There are 4 major ways that collaborative prototyping can be done using the 3-in-1 Universal Axis machine. &lt;br /&gt;
&lt;br /&gt;
First, there is collaboration is CAD verification. Computer Aided Design (CAD) is used in the OSE design process in order to save countless hours during the build. In a proper design process, it is easier to design in virtual CAD - and figure out how everything fits together - rather than going straight to a build and having to fit everything on the fly. The ability to model accurately in CAD is the power that allows OSE to do builds on the scale of a day - as opposed to weeks. However - this works only if the CAD is accurate, because if the CAD drafting is not accurate, it may be impossible to build a machine. CAD quality depends on the skill of the draftsperson. For this reason, it is important to verify the CAD as one of the steps that takes place prior to a build. If mistakes are not caught prior to the build, time and materials are wasted, people can get frustrated, and schedules are delayed.&lt;br /&gt;
&lt;br /&gt;
How do we guarantee that a machine can be built as drafted? With an accurate scale model. First, we must make sure that the CAD of individual parts is correct. This can be assured when accurate CAD files are available - whether the files are generated from measurements, provided by manufacturers, or 3D scanned with the open source 3D scanner. Second, we can verify the actual buildability. This can be done by laser cutting from paper the parts that would be CNC Cut from steel, and then 3D printing the components that we would otherwise get off-the-shelf. For the 3D printing - it is critical that we print every single part - up to bolts and nuts - so the entire assembly we can verify every single step of the build.&lt;br /&gt;
&lt;br /&gt;
This leads to the second use of collaborative prototyping - producing build instructional manuals and videos using the scale models. This allows contributors all over the world to produce meaningful content - without requiring that the contributors have access to a workshop. Since qulaity intstructionals production requires as much effort as the design work - this is another way to contribute to a large, parallel development effort.&lt;br /&gt;
&lt;br /&gt;
The third route to collaborative prototyping is the production of Model Kits for actual products. For example, the Seed Eco-Home lends itself very well for such modeling. Another company, Arckit (ref), is a good model for how we can design the model kit for the OSE’s collaboration with the Open Building Institute.&lt;br /&gt;
&lt;br /&gt;
Fig. Arckit is a great example for modeling. In the OBI case, the models correspond to real building panels and real build procedures. This makes the OBI Architecture Kit a tangible way for people to get involved in meaningful design of future house models.&lt;br /&gt;
&lt;br /&gt;
The OBI Architecture Kit lends itself well to 3D printing as well as laser cutting. 3D printed parts would snap together like Lego blocks.&lt;br /&gt;
&lt;br /&gt;
Another model kit that would be very useful to GVCS prototyping is the Machine Build Kit -  a kit for producing tractors, heavy equipment, and other automated machines. Combined with the OBI Arch Kit for buildings - this would produce the Civiliation Model Kit. The concept for the Machine Build Bit is a mixture of Lego Mindstorms, MakeBlock, Erector Set, Capsela, Box Beam Sourcebook, and Solar Micro Power Cube (all refs) - so that the system can run on solar power. The value proposition is that the kit would once again be based on real buildable parts - thus extending its use from childsplay to real design work.&lt;br /&gt;
&lt;br /&gt;
The OSE Developer Kit + Model Kits pave the way for the 4th route to collaborative prototyping - that of developing open source enterprise. These 2 kits are products in themselves - and can be used as the basis for collaborative business development of distributive enterprise (ref). The concept here revolves around reaching the $1T tipping point for the open source economy - the point at which mainstream adoption of open source economics is likely ($1T is calculated as the 10% tipping point at which viral adoption of open source economics can occur. This coincides with the next Enlightenment of humanity - see Tipping Point on the wiki - http://opensourceecology.org/wiki/The_Tipping_Point  ). This is as large as the combined revenue of Apple ($229B), Google ($79B), FB ($41B), Amazon ($178B), and Walmart ($486B) combined (Microsoft ($90B) - not includes so total is $1T.) - the latter being the single largest corporation in the world.&lt;br /&gt;
&lt;br /&gt;
OSE’s distributive enterprise approach to the tipping point is distributive. The core of OSE’s economic theory is that, by definition, a distributive enterprise serves its customers more effectively than any proprietary enterprise. Thus, a DE has a high likelihood of deposing the corporation http://opensourceecology.org/wiki/The_Corporation  as the dominant societal institution, replacing it with the next phase of the human economy - the open source economy. The transition is in our view likely - because the goal of a distributive enterprise is to produce free enterprise - defined as  distributing wealth most equitably. Current economic paradigms do not internalize distribution in their economic models. The next economy is achievable via full cost accounting and zero competitive waste, thereby achieving zero marginal cost (ref ZMCS). This proposition is simple to grasp, but most challenging to execute. We are not interested in DE as an ideology - but as a pragmatic proposition that simply meets needs more effectively - in an integrated sense -  than current models.&lt;br /&gt;
&lt;br /&gt;
The ask for distributive enterprise is to create the Open Source Everything Store - a networked and collaborative store based on Open Source Microfactories. That is - for people to collaborate on open source product development as a massive parallel effort. Decentralized, distributed, networked production is not a new idea - many people love and claim the idea as their own. To date no successful, economically-viable implementation exists, and certainly not open source. There were many attempts, from the FabLab, Local Motors, 1000 Garages, Ponoko - but none are both distributed and open source. The FabLab is a distributed microfactory concept, but none of its machines are currently open source. FabLabs are are externally funded, and none are used to run a successful business. Local Motors works on distributed production, but their designs and microfactory tools are not open source. 1000 Garages appears stalled. Ponoko and many operations like Ponoko are available. They are successful enterprises, but they do not use open source production tools or software. None of these projects provide open source enterprise information. Perhaps the best examples are 2: first, Lulzbot, which shares its machine designs and enterprise blueprints (blog post from 2014 visit, google Distributive Enterprise) - which makes it a fully open source hardware company - but it has a centralized business model. Second, there is the poster child RepRap project - which is the design/collaboration repository for open source 3D printers. RepRap is responsible for producing most of the consumer 3D printing industry’s companies - both open source and proprietary. (ref) However, RepRap in itself does not have a revenue model. Our own work is also based on the RepRap - it’s the basis that saved us hundreds of development hours - as we could simply build upon their designs. We do have a successfully-demonstrated revenue model of ongoing Extreme Manufacturing workshops.&lt;br /&gt;
&lt;br /&gt;
For The Open Source Everything Store (TOSES), any product developed must include open source blueprints, as well as open source enterprise documentation. Assets such as marketing materials, revenue models, business plans, projections, and entrepreneurship training - among others - must be included to facilitate startup by others. For successful startup - the enterprises themselves must be tested and proven. Thus, case studies of projections, actual revenue, and growth must be included. &lt;br /&gt;
&lt;br /&gt;
With as small an infrastructure as a Personal Microfactory with 3D printing, the CNC circuit mill, laser cutter, filament extruder, and off-shelf components - production of many valuable products can be distributed far and wide. Moreover, open design allows for extended product lifetime - as parts can be upgraded, modifications can be 3D printed, and breakages fixed with readily-accessible parts.  The success of TOSES  revolves around a massive parallel open source product development process - resulting in best-in-class products. These products are then produced by distributed players. Thus, a networked effort could reach substantial distributed production - and distributed sales volumes on the scale of Amazon. &lt;br /&gt;
&lt;br /&gt;
Our claim is that Distributive Enterprise has a good chance of succeeding because of its distributive nature. The cost structure of distributive development is efficient - as it relies on an open source process. We are assuming here that the zero marginal cost prediction - that everything trends to zero marginal cost - which is the competitive advantage of TOSES. However, zereo marginal cost is inherently impossible within the current system. The profit motive of the corporation prevents zero marginal cost, and leads to a permanent inefficiency in human economics. This can be resolved only by a transition away from the traditional corporate IPO form (ref). This is the reason why OSE proposes that a transition to the open source economy is inevitable. However, leading economic theorists such as George Gilder claim that human constructs are not inevitable - they have to be created. Thus, it remains up to human will to decide whether we would like to implement true-cost accounting to transition to the open source economy.&lt;br /&gt;
&lt;br /&gt;
The choice is up to us, and as such we are working on the DE model. Once open source product and enterprise blueprints are available - it means that everyone has access to them. This indicates that efficient production can be distributed into a networked form, which can gobble up Amazon and Walmart. Such a transition to the true-cost accounting economy is the promise of open source economics.&lt;br /&gt;
&lt;br /&gt;
In practice, this requires that open source microfactories, as well as open source materials production facilities - are distributed far and wide. These take abundant natural resources and convert them to a modern standard of living in a distributed way. People can produce with their personal microfactories. Using the 3D printer, circuit mill, laser cutter, and filament extruder - and off-shelf components - people can produce many household goods, electronic gadgets, toys, tools, kitchenware, small appliances, lab equipment (ref), and many others.  The size of the plastic industry alone is $2T - and the size of the injection molding industry is about $100B. Between vaccuum cleaners ($1B), consumer 3D printers ($1B),  cordless drills ($1B in the USA alone), drones, phones, cameras - the market size for those goods is on the order of hundreds of billions of dollars worldwide.  The current limit is 20% of GDP - the manufacturing sector of the economy - or about $16T.&lt;br /&gt;
&lt;br /&gt;
The centralized factory can become obsolete, and many parts of global resource flows can become localized. Specifically - as resource constraints to longer fuel resource conflicts and poverty - humans as a whole have - for the first time in world history - a chance for collective evolution. That simply means that the leading preoccupation transitions from making a living, surviving, or paying off debt - to thriving. This means that the multidisciplinary genius will become much more common - as society reaches a new level. An Einstein could be born every minute. (That makes it 1/250 - or 0.4% of the population.) This means that we transcend William Gibson’s — &#039;The future is already here – it&#039;s just not evenly distributed”. This means that most people will gain access to significant improvement in their quality of life. But this is also not a state of coerced equality as in communism - there will always be outliers who are more ambitious or skilled. But all have a good oportunity to thrive. &lt;br /&gt;
&lt;br /&gt;
CNC Torch and Larger Machines: Heavy Duty CNC Machining&lt;br /&gt;
&lt;br /&gt;
==CNC Torch Table==&lt;br /&gt;
&lt;br /&gt;
The universal axis can handle much larger forces - up to one thousand pounds - when it is scaled up. The universal axis has aleady been used with the 3D Printer and the CNC circuit mill. http://opensourceecology.org/wiki/Universal_CNC_Axis   &lt;br /&gt;
&lt;br /&gt;
We have already built a prototype of the CNC torch table using the Universal Axis, scaled up to a 2x3 meter working area:&lt;br /&gt;
&lt;br /&gt;
Fig: CNC Torch Table build workshop results. (https://www.facebook.com/marcin.jakubowski.378/posts/10213076897374250) &lt;br /&gt;
&lt;br /&gt;
The CNC Torch Table is near release status, and it will be the critical machine used in digital fabrication. The CNC Torch table will be used to cut all metal from flat sheets, which are then welded into 3D machines such as the brick press and tractor. The CNC Torch Table will also be used for cutting holes in 4” square tubing - which is our characteristic life-size erector set design.&lt;br /&gt;
&lt;br /&gt;
Typically, acetylene is used as a cutting gas. In the OSE case, the CNC torch table integrates with the oxyhydrogen production - where water is split into hydrogen and oxygen using electrolysis. These hydrogen and oxygen gases are used as the cutting gases. Oxyhydrogen cutting has been in use prior to the discovery of oxyacetylene cutting in 1903 https://en.wikipedia.org/wiki/Oxy-fuel_welding_and_cutting  - and was preferred for 2x the cutting speed with thick metal. Currently, oxyhydrogen is use whenever a clean cut is required. Otherwise, the gas is 2x as expensive as acetylene. The advantages of hydrogen are the ability to cut aluminum and stainless steel, which acetylene cannot do. Furthermore, if the open source oxyhydrogen generator is used with PV electricity at 1.5 cents per kWhr, then the cost of the gas should go down to about 5x lower than acetylene. Given these advantages, it is interesting to see that oxyhydrogen cutting is not used more commonly in the workshop. The apparent reason for this appears to be the lower price of fossil-fuel derived acetylene. Off-shelf on-demand oxyhydrogen generators appear to be expensive, so they would benefit greatly from being open-sourced. https://www.alibaba.com/product-detail/Gas-generation-equipment-for-oxgen-hydrogen_1950398042.html?spm=a2700.7724838.2017115.380.1b0840b43VI2AU  Hydrogen generators which can produce enough gas for cutting ½” steel are  are available for around $300, not including power supply. http://opensourceecology.org/wiki/Oxyhydrogen_Generator_Cost &lt;br /&gt;
&lt;br /&gt;
The OSE CNC torch table system includes a water bed to minimize smoke and prevent steel from warping while cutting, automatic height control which follows the surface of the metal for optimal cutting, an automatic ignitor, automatic gas control, open source controller, and open source controller software. Each of these piecces has been tested separately, and now we are putting the entire system together to a product that from 2018 onwards will be used to cut all steel for OSE in house. We cut steel for frames of the 3D printer, metal for the brick press, tractor, and just about every other GVCS tool.&lt;br /&gt;
&lt;br /&gt;
==Heavy Duty CNC Multimachine==&lt;br /&gt;
&lt;br /&gt;
The CNC Multimachine is a mill, drill, lathe and other tools in one machine, designed for modularity and flexibility, including rotary indexing and a grinding attachments. It can be used to produce engines and hydraulic motors, threaded parts such as bolts and pipe threads, as well as myriad other parts. The lathe has historically been the cornerstone of precision machining, and is a critical tool in civilization.  It is also another application of the OSE Universal Axis system - using the 2” rod size.&lt;br /&gt;
&lt;br /&gt;
Two other GVCS machines - the induction furnace which melts scrap metal to make virgin steel -  and the Mill which makes Rods and Wire - provide feedstocks for the CNC Multimachine.&lt;br /&gt;
&lt;br /&gt;
Fig. The 2” Universal axis can produce parts with accuracy of 10 microns, based on the deflection of 2” rods with 200 lb of force. This image shows the size comparison between the 2” version - and the 1” and 5/16” versions. The belt drive system can be identical to the smaller machines.&lt;br /&gt;
&lt;br /&gt;
We are interested in developing a core set of modules for a heavy duty machine - including mill, drill and lathe, with rotary and angle tables, plus capacity to function as a screw machine for making threads and bolts. We also include internal threads splines. &lt;br /&gt;
&lt;br /&gt;
Just like with the OBI Arch Kit (make sure reference is correct to rapid prototyping above), the Multimachine Construction Set will allow for modeling with 3D printed parts, which will correspond directly to real life - and thus serve as an educational kit and product. Together with the Multimachine Design Guide and FreeCAD workbench, people will be enabled to build their own multimachines and screw machines.&lt;br /&gt;
&lt;br /&gt;
For the 2” universal axis system, the practical limit is 400 lb of tool force with 0.001 precision and GT2 belt drive. For higher tooling forces, we must use lead screws instead of belts.&lt;br /&gt;
&lt;br /&gt;
The goal of the CNC multimachine is to produce electric motors, hydraulic motors, engines, cylinders, and valve blocks, among others. With a grinder attachment, the idea is to be able to achieve high precision, down to 0.0005, which is the positioning accuracy of the stepper motors at 16 microstepping and 1” GT2 pulleys.&lt;br /&gt;
&lt;br /&gt;
Using the Universal Axis, CNC linear motion control, and CNC rotary chuck control - we can get a wide array of functionality of a screw machine for making various precision parts. With a surface grinder, we can get precision parts down to 25 microns of tolerance. If we build a precision CNC surface grinder, then we can achieve up to 1 micron accuracy for making air bearings.https://www.youtube.com/watch?v=sFrVdoOhu1Q  Air bearings open the possibility of lubrication-free engines and high pressure pumps for storing hydrogen and a prerequisite for certain clean-room semiconductor manufacturing.&lt;br /&gt;
&lt;br /&gt;
==Robotic Arm - trainable for welding + 3D printing==&lt;br /&gt;
&lt;br /&gt;
The robotic arm is a powerful manufacturing tool as it is can move almost as flexibly as a human arm - but with increased precision and strength. Practical tasks that a robotic arm can accomplish depend on the end effector or tool that the arm is holding. For the GVCS, two good applications include automated welding and 3D metal printing using a MIG or TIG welder.&lt;br /&gt;
&lt;br /&gt;
Fig. Robotic welding - [nice pic] is useful for high quality welding to assist the open source renaissance woman. Spot welding or wire welding can be used.&lt;br /&gt;
&lt;br /&gt;
A useful application of robotic arms emerges from trainable robotic arms. Trainable robotic arms are arms which a human operator can train to move as needed. This eliminates complex programming tasks, making robotic collaborators accessible to the general public. An open source software platform already exists for robotic arms in the Robotic Operating System (ROS) project, including trainability.http://moveit.ros.org/  - such that the open source trainable industrial robot is around the corner by building on existing prior art. &lt;br /&gt;
&lt;br /&gt;
==Induction Furnace==&lt;br /&gt;
&lt;br /&gt;
An induction furnace is a device use to melt metal.  Metal can then be recycled - from scrap to useful stock. The advantage of the induction furnace over any other means of melting metal is a clean, energy-efficient and well-controllable melting process. In a typical induction furnace, a water-cooled copper coil with alternating current induces a current in a crucible of metal - hence the name Induction furnace - and that current heats up and melts the metal. Due to the heat being generated within the work piece, energy transfer is extremely efficient.&lt;br /&gt;
&lt;br /&gt;
Fig. In an induction furnace&lt;br /&gt;
&lt;br /&gt;
The induction furnace brings us from the stone and wood age - when stone and wood were the most common materials for making houses and machines - into the iron age - which is synonymous with the industrial age and modern civilization.  &lt;br /&gt;
&lt;br /&gt;
It may be said that modern civilization has culminated with the production of ball bearings. Bearings are a critical component that allows for engines, turbines of modern power to work - and precision machines that use precision ball bearings are used to manufacture these machine. Finally,  vacuum pumps and precision instruments - necessary in semiconductor manufacturing - depend on the use of bearings. As such, the information age today also relies on ball bearings - a combination of material science and precision manufacturing.&lt;br /&gt;
&lt;br /&gt;
==Metal Rolling, Rod &amp;amp; Wire Mill==&lt;br /&gt;
The induction furnace can be used in metal casting, where round rods or billets are cast and then used as feedstocks for metal rolling.&lt;br /&gt;
&lt;br /&gt;
Metal rolling uses rolling dies to shape metal into various profiles, from flat, to round, to angled. &lt;br /&gt;
&lt;br /&gt;
Fig. Metal rolling uses dies of various shapes to produce final stell shapes.&lt;br /&gt;
&lt;br /&gt;
Rolling of thin rounds - or rods - around dies and pulleys - is used to elongate and thin the rounds results in wire - a fundamental building block of civilization. Wire is used for house electrical wiring, suspension,  or fencing.&lt;br /&gt;
&lt;br /&gt;
Fig. A wire drawing machine starts from rod and stretches it to wire through a number of dies. The modular open source version can take rod and turn it into wire of any diameter.&lt;br /&gt;
&lt;br /&gt;
Metal rolling that occurs above the crystallization temperature (700C) is called hot rolling - and it takes less energy to do so as the metal is pliable. Cold rolling occurs at room temperature, and therefore requires more energy to deform the metal - but it also provides more accurate dimensions in the metal.&lt;br /&gt;
 &lt;br /&gt;
==Forging, Ironworker==&lt;br /&gt;
&lt;br /&gt;
The press forge is a heavy duty press than can be used to squeeze metal like butter. When metal is hot, it can be deformed into useful shapes by using a die. Bolt heads are made this way.&lt;br /&gt;
&lt;br /&gt;
Forges can take the form of press, drop, or roll rolling - preferably using the induction furnace for efficient forging. Cold forging may also be done, but that requires larger force for a given deformation.&lt;br /&gt;
&lt;br /&gt;
Forging is useful but the disadvantage is using specialized forming shapes or dies. Thus, the preferable route to forging would in many cases be subtractive machining, metal 3D printing,  or welding - as these are general-purpose procedures that do not require custom forms or dies.&lt;br /&gt;
&lt;br /&gt;
Fig. The press forge can shape hot or cold metal like butter.&lt;br /&gt;
&lt;br /&gt;
==Plasma Cutter, Welder==&lt;br /&gt;
&lt;br /&gt;
The plasma cutter, welder, and induction furnace are high-power electronics that use modern technology for efficiency. By using transistors and inverter circuits instead of large transformers, they can be light-weight and low cost - as the cost of power transistors is 10 cents/kW of power handling ability. This means that the simplest welder circuits can cost only a few dollars in electronic components (not counting wiring, structure, and the balance of system) to get industrial welders on the scale of 10kW (500Amps).&lt;br /&gt;
&lt;br /&gt;
Fig. Diagram of a welder. From first principles, a welder includes power handling electronics, wires, a case, cooling fan, and a welding gun with an electrode, and shielding gas for high quality welds.  In the simplest case - a tungsten electrode creates an arc to the metal and melts the metal, without using filler. This is an example of autogenous welding, where no welding rod or wire is required.  Welding is not complicated - the simplest electric arc welder is a 12V battery connected to a welding rod.&lt;br /&gt;
&lt;br /&gt;
A plasma cutter is a transistor-based power electronic device that cuts conductive metals with a plasma - or ionized gas.  The plasma cutter creates ionized air between an electrode and a work piece. The plasma heats the metal. By directing a focused stream of air around that plasma through a nozzle, the heated metal is oxidized and blown away, creating a clean cut. For comparison,  cut quality  in order of improvement is plasma cutting, oxy-fuel, waterjet, and laser cutting.&lt;br /&gt;
&lt;br /&gt;
Fig. Cut width - or kerf - of plasma, oxyfuel, waterjet, and laser cutting.&lt;br /&gt;
&lt;br /&gt;
Both the plasma cutter and welder are similar to each other. They have similar power electronic circuits.  For a welder or plasma cutter, the main difference is in the gun and electrodes. The gun in both cases has a large copper power wire and a gas line for shielding. For the MIG welder, it also has wire feed. The electrode is tungsten for the TIG welder and plasma cutter, and consumable welding wire for the MIG.&lt;br /&gt;
&lt;br /&gt;
More Power Electronics&lt;br /&gt;
&lt;br /&gt;
Is EDM practical? EDM is a high-voltage spark erosion system for cutting thick metals - where a moving wire at 10,000VDC spark-erodes metals as tiny sparks are established between the wire and metal to be cut. This system is insulated&lt;br /&gt;

&lt;br /&gt;
Disclaimer - Graph of completion&lt;br /&gt;
Here we discuss all the tools, but please remember that in Part 1 of the 4 Part Series, many of the machines are still on the drawing board.&lt;br /&gt;
&lt;br /&gt;
=Agriculture=&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
If you eat, you use a Tractor. Maybe not you directly, but the farmer that grew your food. And food is a $8T industry. The GVCS field agriculture machinery that support this $8T industry &amp;lt;ref&amp;gt;https://www.plunkettresearch.com/statistics/Industry-Statistics-Global-Food-Industry-Statistics-and-Market-Size-Overview/&amp;lt;/ref&amp;gt; are:&lt;br /&gt;
&lt;br /&gt;
Fig 1. The Tractor, Microtractor, Microcombine, Universal Seeder, Spader, Hay Cutter, Hay Rake, Baler, and Dairy Milker, and a Bakery Oven are critical tools of the $8T food industry.&lt;br /&gt;
&lt;br /&gt;
==Tractor, MicroTractor, Bulldozer and Power Cubes==&lt;br /&gt;
&lt;br /&gt;
The tractor is a cornerstone of a farm, construction, or other materials production industries. A tractor has the traction to pull things, and to do utility work with variou implements that can be added to a tractor and use the tractor’s mechanical power through a Power Take-off (PTO). As such, the tractor can be a swiss army knife of heavy duty work. For the smaller individual or home scale, we have the MicroTractor in the set, which is a small, walk-behind or ride-on tractor at the 16-32 hp size that can perform many gardening and utility functions and can fit in a smaller areas where a large tractor would be impractical. If we go up in scale - use a stronger frame and at least 64 hp, and add a bulldozer blade to the tractor - then we have a bulldozer.&lt;br /&gt;
&lt;br /&gt;
The tractor is a machine on the scale of 50-320 hp in the GVCS ecosystem, and unlike traditional tractors, we focus on modular power. We currently use small 16 hp engine units at $17/hp (ref), which is the lowest cost way to obtain engine power, while making maintenance very easy. Like in nature where a tree is made of many branches, our tractor is made of many small engine units. This way, the same design pattern can be used in the 16 hp tractor as in the 320 hp tractor. The price for using larger diesel engines is 2-4 times larger.  &amp;lt;ref&amp;gt;http://opensourceecology.org/wiki/Diesel_Engine_Cost &amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
By using the modularity concept, we create our typical construction set approach for heavy machines. For example, if a large tractor frame is fitted with a bulldozer blade - then we don’t require a separate bulldozer in addition to a tractor. This saves a lot of resources - making technology significantly lower cost to maintain. Exploring the limits of modularity, we found that it is much less expensive to scale our machines usig modular and overbuilt parts that make sense both for small and large machines. For example, we can use 4 of our identical track units, each rated for up to 80 hp - Our track unit, for example, allows for a $30k version &amp;lt;ref&amp;gt; http://opensourceecology.org/wiki/Modular_Track_Unit_v18.01&amp;lt;/ref&amp;gt; that matches the traction of a Cat D7 - a sizeable cost savings comprd to a base price of ½ a million. &amp;lt;ref&amp;gt;https://www.caranddriver.com/reviews/caterpillar-d7e-feature-test &amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Fig. Pattern Language for a Tractor - up to automated control.&lt;br /&gt;
&lt;br /&gt;
The key is making it easy and quick to interchange parts - from small parts to large implements. This is a great challenge for advanced industrial design.&lt;br /&gt;
&lt;br /&gt;
Fig. Industrial smaller parallel and trained configuration. OSE machines can be designed like this, but higher flexibility of the OSE platform can allow for an improved configuration.&lt;br /&gt;
&lt;br /&gt;
Fig. The flexibility of a modular OSE tractor. The modular OSE tractor can be built from the same components, but apply to 16 hp or 320 hp machines while using the same over-engineered components such as the ½” thick steel tracks &amp;lt;ref&amp;gt;Current design is rated for  rated for 40 hp per track or 80 hp with double drive, . (ref - do calculations) and 3600 lbs or 7200 of pull each. Thus, a four-tracked machine can have 29,000 lb of pulling force with direct drive using our current 15k in-lb motors.&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
==Spader, Seeder, Bulldozer==&lt;br /&gt;
&lt;br /&gt;
Your food today is grown largely by tractor-driven  tilling and seeding, unless you’re a breatharian. Tillage in the OSE system chooses the spader as a more progressive technology compared to the age-old plow. &lt;br /&gt;
&lt;br /&gt;
Fig. (Image of 1800 steam tractor with 50 bottom plow) &lt;br /&gt;
&lt;br /&gt;
The spader works essentially like  a bunch of shovels moving rapidly - which till soil without crating a hardpan typical of the more common plow. Manufacturers claim that spading uses 40% less fuel than plowing - because a spader can combine tilling, harrowing, and planting in one operation. &amp;lt;ref&amp;gt;https://www.farmax.info/PDF/Magazine-Farmax-EN.pdf &amp;lt;/ref&amp;gt; A plow, which drags through the soil, requires a lot of wheel-to-ground  traction, whereas a spader requires very little - thus avoiding soil compaction. It takes a spader under 9 minutes and 2 gallons of fuel per acre of field - such that feeding Dunbar Village &amp;lt;ref&amp;gt;A village of 200 -  based on Dunbar’s number https://en.wikipedia.org/wiki/Dunbar%27s_number &amp;lt;/ref&amp;gt; would take 6 hours to plant for a whole year of crop &amp;lt;ref&amp;gt;Assuming field crops planted with a seeder, not slips like sweet potatoes. http://opensourceecology.org/wiki/Acres_Needed_to_Feed_Dunbar_Village &amp;lt;/ref&amp;gt;Thus, one day to plant, two days to harvest - and the village has food for the year. &lt;br /&gt;
&lt;br /&gt;
The tractor and universal seeder is an example of how we approach multiple purpose machines. The tractor is a large-size swiss army knife for doing many different tasks. The Universal seeder is designed to plant all types of seed, from alfalfa to wheat, to tubers, and to live plants like sweet potato slips. Modifying the device rapidly is key to this flexibility.&lt;br /&gt;
&lt;br /&gt;
Fig. Swiss army knife tractor concept&lt;br /&gt;
&lt;br /&gt;
The point of using powerful machines wisely is that in the OSE perspective of lifetime growth -  life could become easy so we can focus on evolving as humans. Our experiment involves building a college campus where peole live this. When they graduate, they know how to organize a village to spend 2 hours per day working on survival, and then the rest of their life they pursue their highest ideals.&lt;br /&gt;
&lt;br /&gt;
The experimental village thus requires one farmer who is employed 3 days of the year, assuming the equipment does not break down, and generates 30 acres * $20k/acre of sweet potato, and $5k/acre for 10 acres of wheat if that is turned into bread  - or $650k worth of food for the community with direct marketing. That is $27k/hour if baking is automated - a decent pay, but not like the $25k/minute rate of Warren Buffett &amp;lt;ref&amp;gt;http://www.businessinsider.com/what-warren-buffett-makes-per-hour-2013-12  &amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Of course these are unreasonable figures, but they do represent the idea. The only way that customer acquisition and marketing costs do not ruin such ideals is in the case of direct marketing - where the on-site farmer-scientist provides for a captive audience of the Dunbar village. If each person eats about $2600 per year &amp;lt;ref&amp;gt;https://www.google.com/search?q=average+cost+of+food+per+year&amp;amp;oq=average+cost+of+food+per+year&amp;amp;aqs=chrome..69i57j0l5.7243j1j7&amp;amp;client=ubuntu&amp;amp;sourceid=chrome&amp;amp;ie=UTF-8&amp;lt;/ref&amp;gt;, feeding 150 people would involve revenues of $390k - but that would be a full time job. We will look more carefully at the business model for resident farmer agriculture in the Enterprise chapter.&lt;br /&gt;
&lt;br /&gt;
Now it would take more time to do a diversified operation, but this is shown just as a baseline to see what’s possible in terms of the effort.  Several Ph.D.’s can be granted to develop a diversified, 40 acre subscription farm, using open source equipment and a captive market, or Local Food Nodes as part of a distribution platform.  &amp;lt;ref&amp;gt;https://localfoodnodes.org/&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The OSE project will develop such a food enterprise both for its campuses and for the outside community - once all the farming machines are done, the aquaponic greenhouse production is optimized, and derivative food processing tools are developed.&lt;br /&gt;
&lt;br /&gt;
The open source tractor can be built at a cost of $125/hp at a scale of 80 hp, compared to $370-$1000 for other brands. It is useful to understand the basic cost breakdown based on off-the shelf parts:&lt;br /&gt;
&lt;br /&gt;
Fig. Cost breakdown of a tractor by Frame, engine, hydraulics, control, automation, and balance of system - $125/hp. (p590MJ)&lt;br /&gt;
&lt;br /&gt;
The cost advantage is less visible at the 32 hp MicroTrac, at $160 per hp - though but a comparable mahine like the tracked Toro Ding costs around  $1000/hp (ref).&lt;br /&gt;
&lt;br /&gt;
Fig. Microtrac with tooth bar bucket can till your garden, and provide valuable utility work. It is an indidspensible utility machine for any prosumer.&lt;br /&gt;
&lt;br /&gt;
==Hay Cutter, Rake, Baler==&lt;br /&gt;
&lt;br /&gt;
If farm animals are involved, then you need these. Or if you want to move large quantities of materials, then a bale is a useful form: from a bale of hay, brush, cotton, cardboard, or plastic - bales allow large scale moving of materials. Bales of aluminum cans are likewise useful for melting down in your induction furnace. If you are making fuel pellets from biomass, plastic pellets for making 3D printer filament - you will need a baler to make 1 ton bales.&lt;br /&gt;
&lt;br /&gt;
==Dairy Milker== &lt;br /&gt;
For animal husbandry, hay baling stores hay for the winter. Unless you are talking about the fish in your home aquaponic system. Dairy products themselves are $116B &amp;lt;ref&amp;gt;https://www.ibisworld.com/industry-trends/market-research-reports/manufacturing/food/dairy-product-production.html &amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
of the global economy - hence the relevance of the dairy milker. &lt;br /&gt;
&lt;br /&gt;
Table: values of the overall food, dairy, cattle, vegetable markets worldwide.&lt;br /&gt;
Combining the dairy milker with computer vision and automation, we envision a solar robotic milker - our MicroTrac with a milking stall - that drives up to a cow to milk her, and then brings the milk back for storage and processing. This allows field milking without human labor for small diversified robofarms that combine the best of regenerative agriculture with modern tehnology to relocalize farming.&lt;br /&gt;
&lt;br /&gt;
Fig. Robotic milker&lt;br /&gt;
==MicroTrac== &lt;br /&gt;
&lt;br /&gt;
A very interesting use arises with a small, solar, robot tractor - the MicroTrac driven by a solar panel. By adding a $10 Raspberry Pi Zero Controller &amp;lt;ref&amp;gt;https://www.adafruit.com/product/3400?gclid=EAIaIQobChMI2rz0mcnd2gIVCzlpCh3MpQgIEAQYAiABEgKi7_D_BwE&amp;lt;/ref&amp;gt; and a $100 solar panel you can be your robotic tractor - for agriculture and other. You can now mow your lawn automatically, and even pelletize it for fuel for a pellet stove. This is possible because today - advanced microelectronics such as the Raspberry Pi is 100 times faster that the first supercomputer, which cost $9M &amp;lt;ref&amp;gt;https://www.theregister.co.uk/2008/01/05/tob_cray1/ &amp;lt;/ref&amp;gt; in 1975.&lt;br /&gt;
&lt;br /&gt;
Fig. A solar-driven MicroTrac concept with solar panel and $50 arduino controller can provide autonomous agriculture &lt;br /&gt;
&lt;br /&gt;
==Bulldozer==&lt;br /&gt;
&lt;br /&gt;
Now add a bulldozer blade to a beefed up, tracked tractor - and you have one of the most powerful devices for regeneration - or destruction - depending on how you use the machine. Bulldozers are powerful earth moving machines - to build roads, grade house foundations, and in agriculture - to build regenerative earthworks for water and erosion. The biggest example is the 12,000 square miles that have been regreened in China - the Loess Plateau. &amp;lt;ref&amp;gt;John Liu reported on this - http://www.aquinta.org/news/2016/10/6/greening-the-desert  &amp;lt;/ref&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Fig.&#039;&#039;&#039; Loess Plateau reforestation&lt;br /&gt;
&lt;br /&gt;
So, if you ever drove on a road - you used a bulldozer. Maybe not you, but whoever graded the road base. &lt;br /&gt;
&lt;br /&gt;
==Microcombine==&lt;br /&gt;
&lt;br /&gt;
The Microombine is used to harvest grains and seeds of any type. This is the core of human harvests world wide. For the OSE case, we have a much more flexible and modular machine in mind. Based on our module-based aproach, we can use the same drive platform as the tractor&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Fig&#039;&#039;&#039;. Showing the base drive platform that can be used &lt;br /&gt;
&lt;br /&gt;
==Bakery Oven==&lt;br /&gt;
&lt;br /&gt;
Humble bread is a $419B global market https://www.ibisworld.com/industry-trends/global-industry-reports/manufacturing/bakery-goods-manufacturing.html . It is the 12th most popular food in the world. https://www.farmflavor.com/at-home/what-is-the-most-popular-food-in-the-world/  And 49% of Americans eat bread  https://www.smithsonianmag.com/smart-news/each-day-50-percent-america-eats-sandwich-180952972/ . &lt;br /&gt;
&lt;br /&gt;
Now bulldozers, tractors, and combines are all good - but the next step for gobal agriculture is the transition to  perennial polyculture  https://www.youtube.com/watch?v=KpJR2yfLUU0  , with only a small fraction of tillage ramaining.&lt;br /&gt;
&lt;br /&gt;
=Construction - 13 Tools=&lt;br /&gt;
If you want to build a charter city or a smaller campus, you will need construction equipment - and a trencher to put in gigabit internet fiber between the locations.&lt;br /&gt;
&lt;br /&gt;
The tools in the construction part outside of the tractors include the backhoe, trencher, cement mixer, sawmill, CEB press, well-drilling rig, soil pulverizer, hammermill. The universal rotor is a tool used in other sectors of the GVCS - and the SeedHouse is a living machine. &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Fig. 13 tools of the construction part of the Global Village Construction Set.&lt;br /&gt;
&lt;br /&gt;
==Backhoe, Trencher, Cement Mixer==&lt;br /&gt;
&lt;br /&gt;
The backhoe or excavator can be used to dig aquaponic ponds, foundation trenches. It can be used to remove stumps, do trenching, and with a grapple it can be used to lift logs or to hoist heavy objects. Backhoes are relatively simple devices - a set of pivot joints that use hydraulic cylinders for their motion - producing thousands of pounds of digging force at the touch of control levers. There are both side-to-side moving backhoes, but a 360 degree rotating backhoe is much more flexible. The small side to side version can be used on a front quick attach of a tractor.&lt;br /&gt;
&lt;br /&gt;
Fig. OSE backhoe from 2010 https://www.google.com/search?q=ose+backhoe&amp;amp;client=ubuntu&amp;amp;hs=ToH&amp;amp;source=lnms&amp;amp;tbm=isch&amp;amp;sa=X&amp;amp;ved=0ahUKEwjLzZKelOLYAhULbawKHQo-DVwQ_AUICigB&amp;amp;biw=1351&amp;amp;bih=731#imgrc=t8j52U9--mn6BM:  mounted on he original lifetrac, a small one used for water line trenching in 2012 http://opensourceecology.org/wiki/File:Bhp1.jpg , and a larger one from 2013 https://www.youtube.com/playlist?list=PL6Jpysxw3Ty-oH4bggp32PR_rPWr8bKC1 . Next iteration is the 360 degree backhoe with remote control drive to facilitate hydraulic line routing.&lt;br /&gt;
&lt;br /&gt;
The trencher in the original GVCS icon is a wheel trencher. We built 2 prototypes, and the next iteration will be a chain-based trencher based on our favorable experience with oversized chain drive on the bulldozer tracks.&lt;br /&gt;
&lt;br /&gt;
Fig. OSE Trencher http://opensourceecology.org/wiki/Trencher - 2011 and 2013 builds.&lt;br /&gt;
The cement mixer is indispensable. Cement has been used in ancient Rome and in mesoamerican temples. Scotland&#039;s County Cork had 23,000 lime kilns at one time - had one kiln per 80 acres. Wood or coal was used as fuel. http://www.lowtechmagazine.com/2013/09/lime-kilns.html  http://www.chapelgatehome.uk/our-blog   Portland cement took over lime cement in the last 100 years, but lime concrete is favorable in foundations becaue it doesn’t crack as easily as Portland. Using modern appropriate technology, lime cement production in solar microfactories is a viable enterprise at the 1 ton per day scale using an open source microkiln the size of a refrigerator. Limestone goes in one end, and lime comes out the other. With such small appliances costing around $1k, cement production can be distributed - while making cement production carbon neutral, annihilating  the current 5% CO2 emission share of the the concrete industry.https://en.wikipedia.org/wiki/Environmental_impact_of_concrete  This is possible in about 50% of America, where the bedrock is made of limestone. That’s a $10B industry in the USA alone.https://en.wikipedia.org/wiki/Cement_industry_in_the_United_States &lt;br /&gt;
&lt;br /&gt;
The cement fryer - a rotary lime kiln - is much like the cement mixer: a Universal Rotor with a heating element. A rotating pipe heated by PV, and an Arduino microcontroller to measure temperatures and guide the process to efficient completion. While not part of the 50 GVCS technologies, it’s a ready derivative:&lt;br /&gt;
&lt;br /&gt;
Fig. PV of the Open Source Materials Production Facility, a solar Power Cube, a Universal Rotor, metal pipe and an Arduino microcontroller constitute the lime cement maker.&lt;br /&gt;
&lt;br /&gt;
If we want to go to the essence of construction, take the backhoe excavator, chase it with a bulldozer with ripper shanks, and then rock under a site could be extracted to build a pond. This rock, if limestone, is feedstock for your lime kiln. In some places, rock outcroppings make access to limestone easy.&lt;br /&gt;
&lt;br /&gt;
==CEB Press , Soil Pulverizer, and Sawmill==&lt;br /&gt;
&lt;br /&gt;
The Compressed Earth Brick press and sawmill are critical tools for construction in that they produce materials. The CEB Press allows one operator to load raw dirt right from the building site to produce about 5000 bricks in a day - enough for a small house. &lt;br /&gt;
&lt;br /&gt;
Fig. The CEB Press is the first machine that we have prototyped, and it is ready for widespread replication around the world.&lt;br /&gt;
&lt;br /&gt;
We have used the soil pulverizer to prepare soil for pressing CEB blocks. The soil pulverizer was used to both pulverize the soil, and its bucket was used to press bricks for CEB construction.&lt;br /&gt;
&lt;br /&gt;
Fig. Soil pulverizer - Aidan on the tractor + loading the brick press by Yoonseo&lt;br /&gt;
&lt;br /&gt;
Our next step on the CEB press is a full soil conditioner which pulverizes soil, adds cement at a measured quantity of 5%, and then loads the mixture into the CEB press - to allow for production of high quality, stabilized block.&lt;br /&gt;
&lt;br /&gt;
Fig. The soil conditioner accepts raw soil from a tractor loader, mixes a measured amount of cement, and loads the prepared mixture into the CEB press for effective production of stabilized block at 12 cents ( 10 cent cement cost for a 20 lb block, and 2 cents gasoline cost). per block in materials. This means that we can build a 1’ thick CEB wall section for $50 in materials.&lt;br /&gt;
&lt;br /&gt;
The sawmill is a machine that can produce dimensional lumber - a staple of construction. Our sawmill is a variety known as a swing-blade sawmill, which has a single blade that can rotate 90 degrees and make a dimensional piece of lumber by going forward and back on a piece of wood.  We chose the dimensional sawmill for its simplicity over a bandsaw mill, as blade sharpening is much easier - and maintenance is the larger cost of any equipment if that equipment is designed for a lifetime.&lt;br /&gt;
&lt;br /&gt;
The sawmill is a good example of how we can use GVCS product ecologies to reduce complexity and reduce the cost of equipment. We design not just individual machines, but machine ecosystems that feed off one another. We can obtain drastic cost reduction by borrowing existing modules from the GVCS. For our case, it makes sense to design the sawmill as a Bobcat standard quick attach implement. We borrow the tractor as a  quick attach point, so that we do not need a bed upon which the sawmill head would otherwise ride. We borrow 32 hp from the tractor Power Cubes. We also  borrow the hydraulic motor which we attach with hydraulic quick-connect hoses. Thus, we have essentially stripped down the entire sawmill to the long carriage with the cutting head - saving $2k https://www.ebay.com/itm/30hp-Kohler-Engine-1-1-8-D-Command-15Amp-Exmark-CH750-0026/132423001888?epid=26011371639&amp;amp;hash=item1ed506a720:g:4YUAAOSwH2VaS3-h  on the engine, $2k https://sleequipment.com/dovetail-utility-trailer-7x20-with-3500lb-axles.html?fee=8&amp;amp;fep=524834&amp;amp;gclid=EAIaIQobChMIws349azn2AIVBqxpCh1rMwbpEAQYASABEgIeHPD_BwE  on a trailer. The greatest advantage would be the setup time - if designed as a quick attach implement, the sawmill can be taken to a log, rested right by the log, and ready for action - as compared to systems where the carriage base must be set up or the log moved into cutting position. If the sawmill can straddle right over a log or be raised with the loader arms, there is no limit ot the size of log that the mill can handle. &lt;br /&gt;
&lt;br /&gt;
Fig. The simplicity of the OSE swing-blade sawmill involves a long linear track mounted as an implement for the tractor. To provide 3 axes of motion - the loader mounting includes height adjustment (z motion), and a lightweight cantilevered head provides side-to-side motion. The cost of about $1500 is significantly lower than the $15k http://www.dltimbertech.com/dl-180-swing-blade-sawmill-10-x-20.html   minimum for a comparable 32 hp sawmill. (ref)&lt;br /&gt;
&lt;br /&gt;
And the sawdust that we generate can be used as animal bedding, insulation, or it can be pelletized to make fuel pellets.&lt;br /&gt;
&lt;br /&gt;
==Universal Rotor==&lt;br /&gt;
&lt;br /&gt;
The Universal Rotor is a fundamental building block for just about any moving machine. It is a combination of rotary motion and a useful tool-head. As a design pattern consisting of a shaft, bearings, and a motor -  a wide array of working tools can be attached to it - so that the Universal Rotor can constitute a drill, a wind turbine,  a wheel, a hammermill, cement mixer, sawmill - etc  - essentially any machine at any size - from small cordless electric drills to a larger 50kW rotor of a wind turbine. &lt;br /&gt;
The Pelletizer , Chipper/Hammermill, Dimensional Sawmill, Rototiler/Soil Pulverizer, Cement Mixer, Well-Drilling Rig, 50 kW Wind Turbine, Microcombine Thresher, and Bioplastic Extruder are direct applications of the universal rotor, and combined with precision machining structures, the Universal Rotor also include the heavy duty CNC Multimhttps://www.opensourceecology.org/portfolio/pelletizer/achine with lathe, drill press, slow cutoff saw, surface grinder, and other machines of fabrication.&lt;br /&gt;
If we can build a Universal Rotor, a Power Cube, and weld together  a supporting structure - then we have - broadly speaking - built 23 of the 50 machines of the GVCS. For example, if we consider the electric motor - it is a a shaft, 2 bearings, a structure, and the ‘tool head’ could be considered the electrical windings that make the shaft spin. Or, if we consider the metal lathe - a part of the Multimachine - then it is clear that the lathe consists of a heavy shaft, 2 heavy bearings, and the tool-head is a chuck for holding work-pieces.&lt;br /&gt;
&lt;br /&gt;
==12. Well-Drilling Rig and Chipper/Hammermill==&lt;br /&gt;
The well-drilling rig is a machine used to dig deep water wells. It consists of a universal rotor which uses 3” (https://www.aquascience.net/grundfos-10sq05-160-230v-10gpm-1-2hp-230v-2-wire-96160140-3-stainless-steel-submersible-well-pump?gclid=EAIaIQobChMIlt-S3PDn2AIVC6tpCh369g34EAQYASABEgJr__D_BwE. 10’ of this pipe store 4 or 6.5 gallons of water. ) or 4” drill pipe to drill down to a depth of 100m or more using hydraulic rotary drilling. In this method, a stream of water is sent down the pipe during the drilling operation to send up tailings and soften the area of the drill point. A heavy duty hydraulic motor spins the drill rod - and new sections of drill rod are attached one after another. When the operation is done, the drill pipe is left underground and a submersible pump is inserted to pump water from the well.&lt;br /&gt;
Fig. A hydraulic deep well pump drilling system explained. The water swivel is the key part here. Otherwise 3” pipe that can be used as  drill pipe and casign is $12/foot. https://www.discountsteel.com/items/Galvanized_Steel_Pipe.cfm?item_id=172&amp;amp;size_no=11#skus  &lt;br /&gt;
The chipper/hammermill is another application of a universal heavy rotor with swinging or fixed blades. This machine shreds or pulverizes materials, and can be as small or large as needed.&lt;br /&gt;
Fig. Hammermill variations with various blades to chip wood or crush rock. A modified version of a heavy rotor can be a grinder. The scale can be from the largest - shredding cars - to the smallest - with small electric motors - if you have hydraulic drive and electric drive.&lt;br /&gt;
&lt;br /&gt;
==The House - Seed Eco-Home and Aquaponic Greenhouse==&lt;br /&gt;
&lt;br /&gt;
The Seed Eco-Home is a living machine - and becase it is the single largest cost of living today, we dediced to include that in the GVCS. (Initially, the house was not in the GVCS - but it was added as the Microhouse.) The  The Seed Eco-Home is the culmination of all the construction machines put to use. Homes are  also about  $3T (https://en.wikipedia.org/wiki/Construction#Industry_characteristics - residential construction is about ⅓ of all construction) market worldwide - which if open-sourced, could provide 30 million regenerative housing jobs for open source home building entrepreneurs Earning $100k each per year. This is 30 million potential collaborators - through we need only about 1000 at this time.&lt;br /&gt;
&lt;br /&gt;
The OSE/OBI https://www.openbuildinginstitute.org/  Seed Eco-Home is a an affordable, expandable eco-home that can be built for ⅓ the cost of a typical home, while including ecological features. Rather than building a large house, we propose starting with a seed home, and then growing it as the need arises. &lt;br /&gt;
&lt;br /&gt;
We are pushing ecological limits in our autonomous house design. The house is  off-grid with PV, provides its own cooking fuel from a biodigester, includes roof-top rainwater collection, and grows its own food with an aquaponic greenhouse. Mowed lawn or biomass is used to provide heating biomass pellets for a hydronic stove that is fueled by pellets. The eventual product vision is a house that  produces fuel for cars as compressed biogas or compressed hydrogen - by splitting water. Thus, we are correcting the oil and gas industry with 100% renewable energy, using simple, proven technologies. We are not relying on advancements in battery technology as a prerequisite to sustainable transportation, and by not requiring scarce lithium for batteries, we are aiming for an abundant and environmentally friendly energy future. http://www.kitco.com/ind/Albrecht/2014-12-16-How-Green-is-Lithium.html  We favor rooftop PV plus electrolysis as the preferred route for transportation fuels, where every house becomes a gas station. Using medium pressure electrolyzers that can produce hydrogen up to 33 atmospheres without needing a compressor - we can readily store hydrogen in large propane tanks or higher pressure steel pipe. &lt;br /&gt;
&lt;br /&gt;
Fig. Seed Eco-Home&lt;br /&gt;
&lt;br /&gt;
Fig. Aquaponic greenhouse glamour shot.&lt;br /&gt;
&lt;br /&gt;
The aquaponic greenhouse is designed to provide a year-round supply of fresh eggs, vegetables, fish, and mushrooms. The goal is to include automated planting with a small Farmbot (https://farm.bot/ . By Shuttleworth Fellow friend Rory Aaronson.), where the resulting deep pots are planted in the  towers. With a 1000 plant growing capacity in the main towers, the greenhouse can provide a robust salad daily, where we plant and harvest 15 plants per day from a small 800 sf greenhouse. A mushroom yield of 1lb is obtained per week from a tower that takes only 1 square foot. We also intend to use automated 3D printed aerial drones for planting seeds directly into towers - a great example of useful product ecology. Local food addresses the issue of food miles, where food travels an average of 1500 miles in the USA before ending up on someone’s plate. https://cuesa.org/learn/how-far-does-your-food-travel-get-your-plate  This is one of the numerous inefficiencies that will be addressed by a more efficient, open source economy. This brings us to transportation.&lt;br /&gt;
&lt;br /&gt;
=Transportation. =&lt;br /&gt;
&lt;br /&gt;
The microcar, truck, electric motor, and hydraulic motor are the 4 GVCS machines directly related to transportation. &lt;br /&gt;
&lt;br /&gt;
The worldwide production of cars is a total of 95M per year, 75% of which is done by the top 15 companies. https://en.wikipedia.org/wiki/Automotive_industry#World_motor_vehicle_production  This lends itself to massive distribution of power. The OSE paradigm proposes instead that there would be on the order of million distributed enterprises - essentially one per 10,000 people. Each facility would produce cars on the scale of dozens or hundreds in the community-supported manufacturing (CSM) scenario. Thus, car producers replace car dealership  - as the producer takes to dealing.  This would go well with a gas station at every home, splitting Seed Eo-Home rooftop water for fuel at a cost of 80 cent per gallon of gasoline equivalent. http://opensourceecology.org/wiki/Hydrogen_Production &lt;br /&gt;
&lt;br /&gt;
Fig. Seed Eco-Home to car fuel infrastructure consists of rooftop water collection, 10kW of PV panels, a storage tank for hydrogen, and compression to 200 bar. Piece of cake if you consider not doing this - wars for oil. This gives us about 100 miles of fuel worth per day in a 100mpg microcar.&lt;br /&gt;
&lt;br /&gt;
==OSE Microcar==&lt;br /&gt;
&lt;br /&gt;
The OSE Microar is a Hydrogen Hybrid Hydraulic (H3) vehicle. Hydrogen is chosen because an internal combustion (ICE) engine running on hydrogen is twice as efficient (40%) as a normal ICE (20%), and only 25% under the 50% efficiency of fuel cells. http://environment.yale.edu/gillingham/hydrogenICE.pdf A hydraulic drive train (71% efficiency) - has a higher efficiency than a continuously variable transmission (60%) for fuel cell electric vehicles - meaning that the humble hydrogen hydraulic car gets a higher mileage than a fuel cell car, at significantly lower cost. At a design weight of only 850 lb, less than ¼ of a typical car, the OSE microcar focuses on moving the passenger, not a large chunk of metal accessory to the core purpose. Lighter cars have a good safety record. Before the S.U.V. boom, the country (USA) had the world&#039;s lowest highway death rate.http://www.nytimes.com/2004/05/05/business/averag e-us-car-is-tipping-scales-at-4000-pounds.html  Additionally, gas mileage for the OSE Microcar is specified for 100mpg. While not as testicular as a Tesla, the OSE specification requires higher self-esteem on the part of the driver to accept acceleration from 0-60 of 12 seconds, as opposed to under 3 seconds for a Tesla Model S.https://en.wikipedia.org/wiki/List_of_fastest_production_cars_by_acceleration&lt;br /&gt;
&lt;br /&gt;
Fig. The OSE Microcar concept.&lt;br /&gt;
&lt;br /&gt;
Can smaller cars are safer? This is controversial. https://www.ptua.org.au/myths/smallcar/  Physics says that energy of motion is proportional to v squared, and data shows that 56% of car deaths are single-car collisions. So unless you are going to hit another oncoming car or an immovable object like a large tree, your tiny car of under 1000 lb  has 36x less energy to dissipate than a Chevy Suburban of 6000 lb. And, the lightest car - the Smart Carfortwo at 1800 lb http://driving.ca/hyundai/accent/auto-news/news/these-are-the-ten-lightest-cars-you-can-buy-in-2015  and it certainly does get eaten up in a frontal 2 car collision with a larger car. And crashes took more than 37k lives in the US http://www.iihs.org/iihs/topics/t/general-statistics/fatalityfacts/state-by-state-overview#Crash-types  , with 20-50x more if injuries are counted. http://asirt.org/initiatives/informing-road-users/road-safety-facts/road-crash-statistics (are injuries better or worse in large cars?)&lt;br /&gt;
&lt;br /&gt;
But this is all before self-driving cars enter the scene - which have been tested for 0 driverless car crashes over 1.8 million miles by Google - with 13 fender benders caused by other cars. http://bigthink.com/ideafeed/googles-self-driving-car-is-ridiculously-safe  In other words, the case is there for super-small, super-efficient cars that are robotically controlled. &lt;br /&gt;
&lt;br /&gt;
What we have in mind follows the standard of the 200 mpg fuel efficiency of the VW  L1 first prototype car, at 640 lb weight, 8 hp, top speed of 75 mph, with tandem seating for 2. https://en.wikipedia.org/wiki/Volkswagen_1-litre_car. The efficiency dropped to 170 mph in a hybrid version - http://gas2.org/2009/09/14/volkswagens-diesel-hybrid-1l-concept-gets-170-mpg-available-by-2013/  If OSE achieves the same with 16 hp instead of 8 hp, and using hydraulics while not needing to go to a hybrid drive-train that apparently reduced its initial mileage performance - then we will have a major victory for open source-  Hydraulic accumulators may be used for peak power.  Plus, we’d like to achieve this with hydrogen as fuel in later versions.&lt;br /&gt;
&lt;br /&gt;
More specifically - our model is an H3E car - including a hybrid electric component.  The hydraulic component is a peak power electric-hydraulic micro-Power Cube of about 40 lb additional weight - powered by the onboard starter battery for its cranking amps.  This additional 30 seconds of a starter battery would double the power of the 16 hp engine - such that burst of energy for passing and sudden acceleration can be achieved easily.&lt;br /&gt;
&lt;br /&gt;
==B The Solar Car==&lt;br /&gt;
&lt;br /&gt;
The Solar Challenge is a fascinating event that shows PV-covered cars traveling 62 mph average across Australia. Granted that the driving is in expensive prototypes ad a sunny country - only in daytime - this still bodes well for the feasibility of solar transportation. The typical cars used are small - surface area of a Toyota Prius - and the OSE version would be twice as large 24x8 feet for 3kW of installed PV + 44 lb Lithium ion batteries + 2.5 kW small engine. http://opensourceecology.org/wiki/Solar_Car This allows for a total of 7kW of continuous power for one hour, or 4 kW total power continuous - at 750 lbs of weight. This just may work - if we 3D print a form frame for carbon fiber layup. 3D printing here may be the enabling technology.&lt;br /&gt;
&lt;br /&gt;
==Truck==&lt;br /&gt;
&lt;br /&gt;
The truck is a medium-size, hydraulic, 80 hp driven vehicle comparable to the Mercedes Unimog. https://en.wikipedia.org/wiki/Unimog  With a design top speed of 62 mph,  a weight of 6550 lb, and a hydraulic power take-off, the OSEmog could function as an agricultural tractor as well. The OSEmog is designed to accept a loader or various implements on the front or back. Using basic hydraulic circuits, the machine would have high and low gear, and speed cotrol via simple flow control valves.&lt;br /&gt;
&lt;br /&gt;
Fig. The OSEmog is a multipurpose truck for carryng loads or operating various implements. With off-the shelf parts, it is designed to be field serviceable, and the working hydraulic fluid can be grown - canola oil with additives.&lt;br /&gt;
&lt;br /&gt;
==Hydraulic and Electric Motors==&lt;br /&gt;
&lt;br /&gt;
Both the car have a choice of using hydraulic or electric drive. The advantages of hydraulics are low-cost, high torque, and simplicity of resulting drive design. Hydraulic motors cost only $10/hp, half that of electric motors - but a typical 40 hp hydraulic motor weighs about 50 lb http://opensourceecology.org/wiki/45.6_Cu_In_Hydraulic_Motor as opposed to about 350 lb https://inverterdrive.com/group/Motors-AC/TECA2-200L-4-Pole-B3-High-Efficiency-AC-Motor-200/ .  Typically electric motors are high speed and need to be geared down - whereas hydraulics can be used largely with direct drive. If high torque electric motors are used - these are more like $100/hp when the controller is included - making the drive system 10x as expensive for larger machines.  Electric motors are sensitive to moisture and dirt, while hydraulics are designed for dirty environments. &lt;br /&gt;
&lt;br /&gt;
We electric motors and generators - in solar electric power cubes - or in wind turbines. But the flexibility, power, and simplicity of hydraulics is a better choice for practical applications - especially when powered by hydrogen and transmitted by canola oil as the hydraulic fluid.&lt;br /&gt;
&lt;br /&gt;
The electric motor can also be 3D printed, making it fit with the OSE product ecology. &lt;br /&gt;
&lt;br /&gt;
Fig. A proprietary, 3D printed, 600W, 80% efficient electric motor. The equivalent is worthwhile to open-source.&lt;br /&gt;
&lt;br /&gt;
Electric motors can be both linear and rotary. In the linear form, they are known as solenoids - very useful devices that are used to make valves. For automation - we use dydraulic valves to control machines like the brick press - and solenoids are used wherever pneumatic or hydraulic controls are needed. This means any automated system - from the water control in aquaponics to the control of an industrial robot.&lt;br /&gt;
&lt;br /&gt;
The electric motor of interest ranges from a small 5W one to power a cordless drill - to the 50kW scale for use in the 50kW wind turbine.&lt;br /&gt;
&lt;br /&gt;
This brings us to the energy sector.&lt;br /&gt;
&lt;br /&gt;
=Energy Tools=&lt;br /&gt;
&lt;br /&gt;
The sun currently shines 10000 times more power to the earth than the entire civilization uses. The implications are profound: there is no such thing as an energy shortage. Energy scarcity is an imagined problem if we talk about actual availability of energy.&lt;br /&gt;
&lt;br /&gt;
We look at it as- it is a high priority to trap solar energy directly - by effective solar design of buildings (Homes and businesses spend about 50% of their energy on heating and cooling. )- and using photovoltaic energy (Solar Concentrator) to generate electricity locally, with wind (50kW Wind Turbine) wherever possible. For machines, the choice is to use hydrogen, charcoal, and compressed biogas. &lt;br /&gt;
&lt;br /&gt;
Hydrogen is by far the most efficient and clean when derived from water (as opposed to refining from oil and gas).  The process gives 0 pollution, and the product of hydrogen combustion is water. The OSE platform calls for provent internal combustion engines running on hydrogen as an immediately executable transition to a renewable energy future in transportation. Leading research institutes, such as the Rocky Mountain Institute (ref), promotes the hydrogen economy as the future, and hydrogen as a future energy source is not controversial if one assumes abundance of fuel feedstocks and distribution of energy production. Solar hydrogen can be produced anywhere, and wind hydrogen can be produced in most places around the world. We do not put such a high stake into batteries or supercapacitors when it comes to energy for cars, simply because chemical fuels are up to 140 times as energy dense. A typical energy density chart typically has chemical fuels off-the-charts good:&lt;br /&gt;
&lt;br /&gt;
Fig. Show specific energy density of storage media, with bats and caps, and chemical fuels, for perspective - https://en.wikipedia.org/wiki/Supercapacitor#/media/File:Supercapacitors-vs-batteries-chart.png. With supercapacitors having 100x less energy storage per weight than Lithium-Ion batteries, while costing 10x as much as ($2.85/kJ) as those batteries ($0.8/kJ), they are super-completely out of the question with today’s technology except for niche applications. Engines are .5kW/kg https://en.wikipedia.org/wiki/Power-to-weight_ratio#Engines  and Fuel (gas, diesel, methane) is 50MJ/kg and hydrogen is 140MJ/kg - or 50-140x more energy per weight than batteries. Given the environmental challenges of mining and recycling scarce metals, there is little case for battery-powered cars.&lt;br /&gt;
&lt;br /&gt;
That means that a non-battery car can lug around a higher percentage of payload (persons, cargo) rather than carrying around more car structure and batteries. &lt;br /&gt;
&lt;br /&gt;
For other purposes, biofuel pellets are desirable for heating fuel (after energy efficiency and solar thermal is maxed out) - such as by an aquaponic greenhouse with a black tubing heat exchanger.&lt;br /&gt;
&lt;br /&gt;
Biofuel pellets can be burned partly to release heat in winter - and if taken out of combustion after the volatile chemicals are burned off but before carbon burns to ash - then we have produced charcoal that can be used in a combustion engine. Thus, dual-fuel hydrogen/charcoal cars are in our view the transportation of the future. We are open to fuel cells entering the scene, and at $134/kW they are almost feasible.https://energy.gov/eere/fuelcells/fuel-cell-technologies-office-accomplishments-and-progress  They are too complex at this point for easy DIY production, so we may revisit this in 10 years if the technology becomes more accessible. Currently, fuel cells require exotic plastics and platinum, both of which are scarce resources. We are aiming for a sub $10k car which can be made with a standard internal combustion engine (ICE) running on hydrogen. Did you know that the first internal combustion automobile in the world ran on hydrogen in 1808? https://en.wikipedia.org/wiki/Fran%C3%A7ois_Isaac_de_Rivaz  Furthermore, ICEs are about 20% efficient - ICEs running on hydrogen are about 40% efficient. For comparison,  fuel cell vehicles are 50% efficient.http://environment.yale.edu/gillingham/hydrogenICE.pdf  Given that the efficiency gain of 25% of fuel cells over hydrogen ICEs comes at a 10x larger cost today, the case for pursuing hydrogen ICEs is much higher than the case for fuel cells. much cheaper H2ICE are seen by many experts as the means to provide a transition between emitting and non emitting transport and stationary system. https://pureenergycentre.com/hydrogen-engine/ &lt;br /&gt;
&lt;br /&gt;
Fig. The possible cost of a fuel cell car today for a 200kW sedan is $26k - and an overall minimum of about $75k. The open source hydrogen microcar is aimed at an under $10k cost and more than 100 mpg using widely available technology. (comparison of components and price, using ref 3 above)&lt;br /&gt;
&lt;br /&gt;
The answer already under our nose that is perhaps the most optimistic case for the energy revolution is solar power - at 0.015 cent per kilowatt-hour - demonstrated in 2016 by the Seed Eco-Home. http://opensourceecology.org/wiki/Hydrogen_Production  This is 4x cheaper than gas turbine electric generation  https://qz.com/135032/fuelcell-energy-fuel-cell-profit/  , and it allows for an equivalent 80 cent per gallon electricity cost for producing hydrogen.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
==The Power Cube==&lt;br /&gt;
&lt;br /&gt;
Our current Power Cube is a universal power unit that can power any of the large GVCS  machines, from cars to lathes to the brick press. The Power Cube is gasoline powered and has a 16 hp engine. We already ran this on charcoal gas - and as such - the same power cube can readily be used in dual-fuel operation - gasoline on the one hand, and charcoal on the other. Once we add the gas production infrastructure - the power cube can run on the hydrogen and biogas production from the House.  Because the pelletizer is part of the GVCS - we can make charcoal pellets from biomass pellets as a byproduct of space heating.  The concept of pellets is important - in that pellets are a flowable fuel. Meaning - that just like gasoline or tradition fuels - it can be stored in a tank and delivered as fuel as if it were a liquid - by using a small auger. This makes pellets a convenient fuel source, which unlike wood - can be used automatically in small machines.&lt;br /&gt;
&lt;br /&gt;
Moreover, the Power Cube can be run on solar energy, allowing for autonomous tractors and solar cars to enter. Solar power cubes are a good idea for shop power - where PV on the workshop roof feeds electric power cubes for hydraulic shop power. Power cubes can also be made very small - on the 1 kilowatt scale. They can also be stacked readily for higher power, so if we want a 160 hp bulldozer, we can do that based on our existing Power Cube.&lt;br /&gt;
&lt;br /&gt;
The Power Cube involves developing open source engines so that they enter the realm of lifetime design public technology. A universal version of an open source engine means that such an engine could be maintained and produced in a distributed fashion, bringing it closer to appropriate technology with a lifecycle that includes more reusability of parts.&lt;br /&gt;
&lt;br /&gt;
Fig. The Power cube and its different fuel sources - from gasoline, to charcoal, to compressed biogas, hydrogen, and electric.&lt;br /&gt;
&lt;br /&gt;
The large torque of hydraulics makes them very flexible for driving a wide range of machines. A small power cube, such as a 300W version running on a single solar panel, can be used to drive a 2000 lb MicroTrac as a practical, autonomous tractor.  The idea is that the machine would move very slowly - all day - on solar power. This is afforded by that fact that hydraulics have high torque at any speed - making this a perfect application of solar energy to autonomous, robotic tractor drive via a small microcontroller such as a $10 Pi Zero with Wireless.https://www.adafruit.com/product/3400   Thus, we can pull chicken tractors or pig tractors with a solar robotic tractor for a diversified agriculture operation.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
Autonomous animal tractors are another possible application of Power Cubes…&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
==The Gasifier ==&lt;br /&gt;
&lt;br /&gt;
The OSE  gasifier is a device that converts charcoal into gas for fueling engines. Note that this gasifier uses charcoal that is produced as a byproduct of space heating. The gasifier is a metal container filled with charcoal, which upon being lit via in a small burn zone with an air inlet - burns and produces gas. This gas can be used as fuel in a regular internal combustion engine. The power of this lies in that with minimal modifications, a standard engine can be fueled by charcoal - which is derived from wood or other biomass.  This means that wherever plants grow - they provide a distributed and practical fuel source byond oil wars. https://www.cnn.com/2013/03/19/opinion/iraq-war-oil-juhasz/index.html  To produce charcoal, biomass is first pelletized. Burning pellets for space heat - and removing them from the burn before they turn to ash - produces charcoal pellets.&lt;br /&gt;
&lt;br /&gt;
Fig. Infographic. Space heating produces charcoal in the OSE ecosystem.  The Gasifier vaporizes charcoal, which is then burned in a standard engine. This process can be used to fuel cars - no engine modification required.&lt;br /&gt;
&lt;br /&gt;
The first reaction may be that if we turned plants into vehicle fuel - then we would destroy all of nature. That is not true, because there is plenty of biomass reserve that can be used to fuel the entire American car fleet, which uses about 60% http://needtoknow.nas.edu/energy/energy-use/transportation/  of all the energy in the transportation sector. Did you know that the largest single crop in the United States is lawn? There are 40 million acres of turf grass. http://scienceline.org/2011/07/lawns-vs-crops-in-the-continental-u-s/  What if we turned lawns into fuel crop, while increasing esthetics and reducing herbicides? Yields of grass are 4 dry tons per acre https://en.wikipedia.org/wiki/Biomass  - and if charcoal is produced at 25% efficiency - that is one ton of charcoal per acre - or 40 million tons of charcoal can be harvested from lawns alone, with no effect on food production, while increasing the ecological diversity of lawns. The average american uses 500 gallons per year of fuel.  https://www.treehugger.com/culture/pop-quiz-how-much-more-gas-do-americans-use.html  Lawns could thus provide ¼ of the entire car fleet fuel in the USA! (Charcoal is ¾ the energy content of gasoline by weight. At about 3 kg/gallon - 500 gallons is 1500 kg- about 1.5 metric tons - so 33M people could be supplied by fuel from lawns. If 95% of households have cars - https://photos.state.gov/libraries/cambodia/30486/Publications/everyone_in_america_own_a_car.pdf - and household is 2.6 - there are about 120M drivers in the USA. Thus  - ¼ of US drivers can be fueled by lawns.) This is at the crappy USA 23 miles per gallon - so increasing fuel efficiency to 100 mpg https://www.motherearthnews.com/green-transportation/green-vehicles/build-your-own-car-zm0z13amzmar with super-efficient micro-cars could mean that the entire US car fleet is supplied by fuel from grass. Efficiency and ecology - as opposed to battery technology with questionable environmental side effects and its centralization based on scarce resources - make the OSE platform converge on biomass and hydrogen as the fuels of choice. The OSE platform reserves the role of batteries only as a small part of vehicular power, not the backbone of the auto industry. &lt;br /&gt;
&lt;br /&gt;
The biomass route needs no technical invention to realize - today - and is also a carbon-neutral route. From the OSE perspective - hydrogen is clean (it produces water as the byproduct) but not better on ecological grounds (it does not contribute to biological ecology) - but it is much better on efficiency grounds.&lt;br /&gt;
&lt;br /&gt;
When discussing biofuels, it is important to point to the food-fuel-fiber integrated agroecology route as the preferred OSE route to agriculture. As opposed to genetic engineering to produce super-crops, the OSE platform favors ecological integration over genetic manipulation - so that we avoid creating super-problems at the same time. The ecological route means that we learn more about dealing with integrated ecosystems, not trying point solutions (genetic engineering) as a cure. When dealing with powerful technologies like genetic engineering, we must pay attention to unintended consequences. The current economic paradigm of profit maximization is not compatible with care in the use of genetic engineering. We favor increasing productivity by stacking yields of multiple crops that work harmoniously in a polyculture setting - with tree crops as a significant component. For us, the breakthrough work of Badgersett Research Farm is seminal in providing this leadership. They are developing perennial crops (hazelnuts and chestnuts) that could serve as a viable replacement for soybeans and corn. (ref).  Hazelnuts and chestnuts provide the same nutrition as their annual counterparts - but are perennial - and therefore do not contribute to the average 4 ton per acre annual soil erosion in the United States. (ref). Let me repeat that - the avarage topsoil loss in the United States - per acre - is 4 tons. What that means is that agricultural soils today are so depleted that they could not grow crops if it were not for the heavy inputs of fertilizers. The biological activity of commercial farmland is severely depleted (ref), not sustaining the soil food web of microbes that bring fertility back to the soil. (ref). Our proposition for perennial polyculture - is not new (ref on seminal works, Tree Crops, Regrarians, etc) - and it can produce food, fuel, and other materials.&lt;br /&gt;
&lt;br /&gt;
To improve the world, all you need to do is plant trees. Desertification still claims an additional ______________ square miles every year, and it would be good to reverse that.&lt;br /&gt;
&lt;br /&gt;
It takes less than 60x the land area to produce solar hydrogen compared to the land area required to grow biofuel crops.  Between biofuel (easy) and hydrogen (hard), humanity’s fuel needs can be met. Let’s look at numbers: we already said 300 gallons of fuel equivalent per acre (enough to fuel one car for a year at a fuel economy of 40 MPG https://www.google.com/search?q=average+miles+per+year+usa&amp;amp;oq=average+miles+per+year+usa&amp;amp;aqs=chrome..69i57j0l2.7415j0j7&amp;amp;client=ubuntu&amp;amp;sourceid=chrome&amp;amp;ie=UTF-8 ) fuel consumption -  roughly one gallon per day. If we apply this to hydrogen - 50kWhr of electricity is required to produce 1 kg of hydrogen, roughly one gallon gas equivalent. This can be obtained from a 9 kW PV array - running 6 hours per day - 54kWhr. The space required for a 9 kW array is 60 square meters if the panels are 15% efficient. An acre is 4000 square meters - so producing solar hydrogen requires 66 times less land area than growing the equivalent grass. Our materials cost for 9 kW of solar panels is under $9k. So one can obtain 20 years of hydrogen fuel for a PV investement cost of $17k.&lt;br /&gt;
&lt;br /&gt;
Fig. Home hydrogen production. The OSE open source goal is $9k for PV panels, $2k for storage, $2k for pump, $2k for plumbing, and $2k for the electrolyzer. That is $17k for a lifetime supply of hydrogen. Compare to gasoline - $1250/year on average. Payback time for  home fuel station is 14 years in the USA and 7 years in Europe. We intend to make hydrogen production a standard feature of the Seed Eco-Home.&lt;br /&gt;
&lt;br /&gt;
Add a paragraph about renewable energy plantations - perennial polycultures for fuel, food, fiber. &lt;br /&gt;
&lt;br /&gt;
Fig. Basic economic model for renewable energy plantations involves $x/acre in coppiced fuel, $1000/acre in nuts, and $2k/acre in sustainable chickens that fertilize the crop via autonomous chicken tractors.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
==Heat Exchanger==&lt;br /&gt;
&lt;br /&gt;
The heat exchanger is a device that takes heat from one medium and puts it into another. For example, in the Seed Eco-Home - we have a hydronic stove with heat exchanger which is used to heat water for heating the house.&lt;br /&gt;
&lt;br /&gt;
Fig. Hydronic stove with heat exchanger. A heat exchanger heats water, and if that water is boiled, it can be used to run a steam engine or turbine. Small steam engines have been used for shop power 100 years ago, and they can be used even more effectively today. You can get a working kit for $275 on Ebay.&lt;br /&gt;
&lt;br /&gt;
Simpler examples of the heat exchanger are the Hillbilly Heater. This device traps solar heat and puts it into water circulating through the black tubing. This energy is released through another coil in the aquaponic ponds, for example. A closed heat exchanger means that the water in the black tubing does not mix with the pond water. Or, this heat exchanger could be an open heat exchanger, where the water is heated and then used as hot water in a shower - so that a steady supply of new water is fed through the exchanger instead of just circulating - as in the pond heating case.&lt;br /&gt;
&lt;br /&gt;
Fig. The hillbilly heater can be used to heat ponds or to provide hot water for the house.&lt;br /&gt;
&lt;br /&gt;
==Modern Steam Engine==&lt;br /&gt;
&lt;br /&gt;
The modern steam engine is an engine that produces power from steam. The industrial economy was created by steam power. And steam turbines are the main way that power is generated today. &lt;br /&gt;
&lt;br /&gt;
A modern steam engine is a small engine that makes sense to build wherever space heating is involved. For example, a centrally heated building could be generating power at the same time as its being heated - if a heat engine with a generator is added to the system. Thus, we are piggy-backing on an existing power source, while using all the waste heat.&lt;br /&gt;
&lt;br /&gt;
Under 500 hp - or in any small scale installation - it is more effective to have a steam engine as the engine of choice. Above 500hp, it is more effective to use a steam turbine. Large power plant steam turbines reach 50% efficiency. https://en.wikipedia.org/wiki/Steam_turbine#Practical_turbine_efficiency &lt;br /&gt;
&lt;br /&gt;
A flame-fired or solar-powered heat exchanger can produce steam - for electricity generation. This makes sense for combined-heat-and-power systems. Most of today’s electricity is produced by water that is boiled in power plants to provide electricity via steam turbines. (ref) This can be done effectively on a scale of 500 or more horsepower - which is village scale, not home scale. For the smaller scale, a small steam engine can be used. For this reason, we have incorporated a modern steam engine into the GVCS - as a machine for producing electricity on top of a heat source. This could be done in our hydronic stove - where the water goes from the steam engine and then to house heating after some power has been extracted for electricity. It makes sense to convert the heat into high grade electricity - when the steam engine is connected to a generator.&lt;br /&gt;
&lt;br /&gt;
Fig. Hydronic stove with power generation.&lt;br /&gt;
&lt;br /&gt;
Did you know that the modern steam engine - a specific advanced version -  is more efficient than the internal combustion engine? The Cyclone engine is a high tech, high temperature steam engine made of stainless steel and exotic materials - with thermal efficiency over 30%. http://cyclonepower.com/ &lt;br /&gt;
&lt;br /&gt;
There is another steam engine that received a lot of attention on the internet but appears not to work well - the Green Steam Engine. We do not endorse the engine, as suggested by Tom Kimmel of Kimmel Steam Power  http://kimmelsteam.com/green-robertengine.html  - and you can read more in an old blog post. (http://opensourceecology.org/steam-meet-report/ . I have since contacted Mr. Greene for data on Feb 1, 2018, but I have not been presented with any data.)&lt;br /&gt;
&lt;br /&gt;
All together, the modern steam engine is valuable for household power, if the Power Cube is used for mobile power. Would would be the cost of a steam engine add-on to a household infrastructure? Small models of ¼ hp are available for under $300 in parts, (http://ebay.to/2EwmHWt ) and these are scalable readily to larger sizes. The current seed eco-home stove has sufficient power to run this engine, so only an additional pump would be required to feed water to this system.&lt;br /&gt;
&lt;br /&gt;
Integration of such a system would work well if pelletized biomass were used as fuel - and subsequently - charcoal would be produced for use in cars as a byproduct of household power generation. An interesting milestone would be an automated biomass energy system from an autonomous tractor-pelletizer - up to the production of charcoal as car fuel using gasifiers - all from one’s former lawn converted to bioenergy crop.  In such case, nickel iron batteries may be desirable in so far as excess energy storage from daytime solar power.&lt;br /&gt;
&lt;br /&gt;
Fig. The energy product ecology of the Seed Eco-Home includes solar hydrogen, biogas for cooking, and production of car fuel from the lawn.&lt;br /&gt;
&lt;br /&gt;
==Solar Concentrator==&lt;br /&gt;
&lt;br /&gt;
The modern steam engine equation becomes much more exciting when solar concentration is used. Using 30% efficient, modern steam engines, proven linear solar concentrators, and a night-time storage system based on large, insulated propane tanks with hot water - it is possible to produce an off-grid energy system with $100/kWhr energy storage costs - 4x cheaper than lithium ion batteries. https://en.wikipedia.org/wiki/Lithium-ion_battery  A breakthrough company - Terrajoule - has already demonstrated this. Then the question becomes - if this has already been shown in the first prototype of Terrajoule, why isn’t everyone doing this when the technology is all proven? One cannot beat the simplicity of water and solar heat as the ultimate storage medium. &lt;br /&gt;
&lt;br /&gt;
What can water really do? When water is heated but not allowed to expand, it turns to what is known as saturated water. A saturated liquid is a liquid whose temperature and pressure are such that any decrease in pressure without change in temperature causes it to boil. In other words, if a tank was not holding the water at pressure - that water would turn into steam.&lt;br /&gt;
&lt;br /&gt;
Just how much energy can that water store at a medium pressure? A lot. Looking at the total heat content of water that would otherwise turn to steam, but is held under pressure at 18 atmospheres (250 PSI) in a tank instead http://opensourceecology.org/wiki/Saturated_Water  - we see that each kilogram of such saturated water holds about ¼ kWhr of energy. That means that a 10,000 gallon propane tank can store about 4MWhr of energy! We can extract that energy with a modern steam engine, where steam engines from the 1950s got to about 30% efficiency. https://en.wikipedia.org/wiki/Uniflow_steam_engine   After all the losses, we we would have 300kWhrs of electricity when the modern steam engine runs a generator.&lt;br /&gt;
&lt;br /&gt;
We can scale that down to a residential system - just a 1000 gallon propane tank - and 30kWhrs of electricity produced.&lt;br /&gt;
&lt;br /&gt;
Fig. Cost and energy of a home-scale solar energy storage system using water and modern steam power. From energy content of 400kWhrs to 30kW hours of electricity is quite doable using proven technologies, at ¼ the cost of battery storage.&lt;br /&gt;
&lt;br /&gt;
==Nickel Iron Battery==&lt;br /&gt;
&lt;br /&gt;
Nickel-Iron Batteries are long-life batteries that have a track record of lasting 50 or more years. Unlike other batteries, these can be discharged fully without decreasing their lifetime. These are chosen for the Global Village Construction Set specifically for their long life - and becuase nickel and iron are not scarce resources. While heavier and 2x more expensive than lithium ion batteries, (Read an intereresting pro-con discussion - http://opensourceecology.org/wiki/Nickel_Iron_vs_Lithium_Ion_Battery_from_Tesla_Motors ) they make up by their long lifetime, and lend themselves to decentralized production. New developments are in progress, ( https://news.stanford.edu/news/2012/june/ultrafast-edison-battery-062612.html )  though OSE does not rely on new developments for feasibility given that OSE internalizes social and environmental aspects for true cost accounting. The cost is currently high because production volume is low - only 2 US manufacturers. Based on a nickel price of $6/lb and iron at 25 cents/lb, and a weight of 100 lb for 1kWhr - and a 20% content of nickel in nickel iron batteries https://www.solarpaneltalk.com/forum/off-grid-solar/batteries-energy-storage/ni/7052-how-much-nickel-is-really-in-a-ni ckel-iron-ni-fe-battery - the base materials cost of materials in Nickel Iron batteries appears to be $150/kWhr. That is similar to lead acid batteries and ½ of lithium ion costs - but if the lifetime of these batteries is really 50 years, then they are 5-10x cheaper than other batteries based on lifetime.&lt;br /&gt;
&lt;br /&gt;
According to recent research: https://link.springer.com/content/pdf/10.1007/s10800-015-0911-3.pdf &lt;br /&gt;
&lt;br /&gt;
There are many reasons favouring the use of NiFe cells as cost-effective solutions to store grid-scale amounts of energy, such as low cost of raw materials, environmental friendliness, electrical abuse tolerance, long life (in the order of thousands cycles of charge and discharge) and compatibility with photovoltaics (PVs). Due to the nature of the heavy metals involved in its construction this technology is suitable for stationary low gravimetric energy applications (30–50 Wh kg-1 ). As a consequence, there are good reasons to foresee a large scale utilization of this technology. Due to their outstanding safety properties (zero flammability, fail safe, no over/ under charge), low cost and long lifetime, we anticipate that they will receive widespread public acceptance for customer-connected energy storage.&lt;br /&gt;
&lt;br /&gt;
It is our hope that the nickel iron battery would be only a small fraction of electrical power storage needs in the future - such as replacing 5-year lifetime starter batteries in vehicles. For night time electricity, it would be useful for warmer regions to use solar concentrator saturated water storage - as one possibility - or solar hydrogen as another.&lt;br /&gt;
&lt;br /&gt;
In colder areas, biomass is typically available as an abundant energy crop - where PV may not be adequate if there are weeks without sun. The exact mix of solar concentrator electric, PV, wind, charcoal, biomass, biogas, and hydrogen is to be determined at Factor e Farm as we measure the value of all these systems side by side. The main requirement for OSE is true service to humanity, environmental regeneration, and freedom from resource conflicts.&lt;br /&gt;
&lt;br /&gt;
==50 kW Wind Turbine==&lt;br /&gt;
&lt;br /&gt;
A wind turbine converts a renewable form of energy - wind - into electricity. It provides a good backup to PV electricity, as wind typically blows when the sun is not out.&lt;br /&gt;
&lt;br /&gt;
We propose a vertical axis wind turbine for the initial OSE version based on integration with hydraulics and the Universal Rotor.  A simple system can consist of a pole mounted 40 hp hydraulic motor ($400), serving as a pump - which transfers fluid power to an on-the-ground hydraulic motor ($300) + 24 kW generator ($1000). The power generator related costs are ~ $2000 here, and the rest is the tower and structure. With $6k spent on the materials for this wind turbine, this would be $250/installed kW in materials costs - with installation being 15% on top of this http://www.esru.strath.ac.uk/EandE/Web_sites/14-15/XL_Monopiles/cost.html  - a very attractive package in a sweet spot of cost for readily-available components. This is compared to $1590/kW standard costs of large scale wind installations. https://www.awea.org/falling-wind-energy-costs &lt;br /&gt;
&lt;br /&gt;
The OSE design features a generator that is mounted on the ground, with only the hydraulic motor on top of the tower. This facilitates maintenance considerably. The savings is due in part to the great simplification of the nacelle - in the OSE case, the vertical axis design doesn’t have a yaw mechanism - it’s just a hydraulic motor that accepts wind from any direction. These turbines are not as efficient in terms of wind capture as they are lower to the ground - but the low capital + maintenance costs make up for the lower efficiency. Because they can be packed more tightly in the same area, however - VAWT wind farms can actually produce 10x the energy of a propeller-type wind farm. https://en.wikipedia.org/wiki/Vertical_axis_wind_turbine#Advantages  They also self-regulate their speed, so they do not need a braking meachanism for overwind conditions.&lt;br /&gt;
&lt;br /&gt;
Fig. OSE VAWT concept. Simplification of design include ground-mounted generator, yawless rotor, screw pile foundation https://en.wikipedia.org/wiki/Screw_piles#Modern_Use_and_Benefits  , and braking via the hydraulic motor as the overspeed protection. The wind turbine module is designed for 24 kW, and it includes the Electric Motor/generator, Universal Rotor, Hydraulic Motor, Power Cube, and Universal Power Supply for managing power.&lt;br /&gt;
&lt;br /&gt;
8. Universal Power Supply&lt;br /&gt;
The Universal Power Supply (UPS) is the last of the energy machines. It is a universal device for powering large electronic machines - induction furnaces, welders, plasma cutters, laser cutters - and for controlling power delivery and transmission to homes or electric cars. It is also used for charging. The UPS has feedback such that it would know when batteries are full, or for optimizing the power transfer into a load of metal that is melted with the induction furnace. &lt;br /&gt;
&lt;br /&gt;
The Universal Power Supply in general  converts AC and DC into voltages and currents of any amplitude and frequency. The UPS is scalable from a few watts to 20kW based on the same design of modules.  The Universal Power Supply can also be used to condition power from the wind turbine or PV system and pump it into the grid. It can also be used as an inverter to convert DC to AC, or it can be used to control the speed of an electric car. It can also be used to step power up to high voltage for power transmission over longer distances, such as up to the 69,000 volts for rural power lines. &lt;br /&gt;
&lt;br /&gt;
As with the mechanical machines, the Universal Power Supply is based on modular design, such that we can arrive at a Construction Set. Just like power units, wheels, shafts, hydraulic motors, control valves, and frames can create any mechanical industrial machine, so can a small number of modules provide just about any electrical power function in the Universal Power Supply. These modules are mainly: a microcontroller, a current measurement device, a transistor, wires, laminated cores, ferrite beads,  diodes, optocouplers, resistors, capacitors, and inductors - plus a few mechanical components such as plugs, cases, cooling systems. With advanced transistors that now cost $1 per kW of power handling, large power electronic devices can be built on the cheap if open source knowhow is available.&lt;br /&gt;
&lt;br /&gt;
Wires and metal cores themselves produce a wide range of devices: inductors, transformers, relays, solenoids, switches for large currents, electric motors, spark generators, electromagnets, and other devices. &lt;br /&gt;
&lt;br /&gt;
Lasers, charge controllers, inverters, welders, induction furnaces, plasma cutters, oxyhydrogen generator power supply, and motor controllers are all functions that can be generated with the Universal Power Supply. These are all based upon currents and voltages at different frequencies and amplitudes that perform radically different functions. This has to do with the nature of electricity - jus like a few atom types (100 or so) make up millions of different substances that are all around us - so can electricity be manipulated to perform a wide array of functions. Any of the above devices consist of a microcontroller and a power transistor - along with some resistors, capacitors, and inductors. The microcontroller could be an Ardduino or a Rasperry Pi - which now cost as little as $5 for these small computers running with a 700MHz cpu. This CPU - via software - can produce a voltage of any amplitude and frequency using transistors. In other words - a ‘brain’ - the CPU - can massage electrons so they maifest at any voltage or frequency - by using transistors - or devices where a small signal from a CPU controls a large voltage. Essentially - a transistor is a switch - which is activated by a small signal.&lt;br /&gt;
&lt;br /&gt;
For example - taking DC voltage - one can make it pulsed and appear as an oscillating sine wave. This is an inverter for household power - which can for example take electricity from PV cells and convert that into household current. Or - this same inverter can be pulsed much faster to create a 30kHz voltage used in an induction furnace. And regulation can happen - such as an induction furnace delivering power most effectively to the molten charge - when the same microcontroller can measure the voltage, and change the frequency of the applied voltage to pump power more effectively into the melt. &lt;br /&gt;
&lt;br /&gt;
This is all possible because superfast microcontrollers, and high power handling transistors - can all be purchased now for a few dollars.&lt;br /&gt;
&lt;br /&gt;
Energy Summary&lt;br /&gt;
&lt;br /&gt;
Combining biomass, charcoal, biogas, wind power, the solar concentrator,  steam electricity, hydrogen, PV - and the electronic controls of the Universal Power Supply -  makes for a resilient power infrastructure without necessitating resource conflicts.&lt;br /&gt;
&lt;br /&gt;
=Open Source Microfactory=&lt;br /&gt;
&lt;br /&gt;
The Open Source Microfactory (OSM) is the crown jewel of the Global Village Construction. It is the part that allows for GVCS self-replication - in that the Open Source Microfactory allows for the production of all the  GVCS tools - including the Microfactory itself..&lt;br /&gt;
&lt;br /&gt;
The Open Source Microfactory is broken into 2 main parts: precision CNC tools, and metal production tools. The CNC tools - which stands for Computer Numerical Control - are automated machines that can be programmed to build things - from small parts, to engines, and everything in between. The metal production tools allow for the production of virgin steels from scrap. The steel that can be produced with the GVCS metal tools thus allows for the creation of advanced civilization - wherever there is access to scrap steel. Scrap steel is abundant, and so it iron ore from which steel is made. Iron is the 4th most abundant element in the earth’s crust - after oxygen, silicon, and aluminum. https://en.wikipedia.org/wiki/Abundance_of_elements_in_Earth%27s_crust &lt;br /&gt;
&lt;br /&gt;
What if there is no scrap steel available? We can go to aluminum - which is even more abundant in terms of the crust’s composition. Aluminum is found in common clay. Clay is aluminosilicate, from which aluminum can be extracted. Because Aluminum is so abundant - the GVCS goes so far as the extraction of aluminum from clay. This is intended to break through any notions of scarcity in today’s civilization.  Clay is abundant, and it’s an essential part of the GVCS: compressed earth blocks, soil for growing food, clay for 3D printed pots and cookware - in addition to the production of aluminum metal.  &lt;br /&gt;
&lt;br /&gt;
Fortunately - silicon is even more abundant. We get solar cells for producing electricity from silicon - a core technology for the GVCS such as in the Seed Eco-Home. In less than the time it takes to read this paragraph, the sun will have provided as much energy to Earth as used by all of human civilisation in one day. Thus silicon solar cells are important. And silicon is used to make semiconductors - so silicon creates the computer age.&lt;br /&gt;
&lt;br /&gt;
With the Open Source Microfactory - we thus aim to show that literally, modern civilization may be created -  from dirt and twigs. This can happen on any parcel of land - as solar cells can easily produce about 500kW of energy - from an acre. So a facility such as the OSE headquarters can produce all the technology required to produce an advanced civilization. For example, 500kW of solar energy - or 3MWhrs per 6 hours of daylight - can produce 200 kg of aluminum per day. Aluminum requires 15 kWhr per kilogram to smelt. (http://wordpress.mrreid.org/2011/07/15/electricity-consumption-in-the-production-of-aluminium/ . This one says ,05 GJ/kg - http://wordpress.mrreid.org/2011/07/15/electricity-consumption-in-the-production-of-aluminium/ )Aluminum is energy intensive - but its production may one day be improved for more environmentally-sound production - as can any other process by internalizing environmental costs.  https://www.sciencedirect.com/science/article/pii/S0360544207001065#! &lt;br /&gt;
&lt;br /&gt;
This shows how energy intensive aluminum production is - but its 3x better weight to strength ratio compared to steel makes it a desirable product. With the proposes 200kW solar microfactory - we can produce 80 kg of aluminum per day. That’s not a lot - but acceptable as a proof of concept for an appliance-size machine.&lt;br /&gt;
&lt;br /&gt;
Aluminium is the most abundant metallic element in the Earth’s crust (about 8%) and the&lt;br /&gt;
second most widely used metal next to steel. The aluminum production process involves taking ordinary clays such as abundant kaolin clay - and leaching out alumina with hydrochloric acid to produce Al203, which is subsequently turned to Aluminum via electrolysis at a cost of 15 kWhr per kg of aluminum produced. For reference in terms of energy requirements - this is like converting one gallon of gasoline to one kg of aluminum. That’s a lot of energy. But the main point here is that this can be done anywhere where there is soil - clay for making aluminum is an abundant feedstock.&lt;br /&gt;
&lt;br /&gt;
If we talk about the carbon dioxide emissions - whether from aluminum or steel production - the way we propose to make it sustainable is to make the CO2 recyclable. If the carbon involved in the reactions for producing metals - or for that matter any other product - comes from charcoal derived from biomass - then the industrial process is regenerative as the plants that were used to produce the charcoal took the carbon out of the atmosphere in the first place. Thus, a sustainable industry is possible  when civilization evolves to using charcoal  instead of fossil fuels. &lt;br /&gt;
&lt;br /&gt;
However, it should be stated that CO2 in the long run may be more advantageous for ecology - even from fossil fuels - if that CO2 yields more plant growth. While many people see CO2 per say as a global warming problem - it is also possible that the CO2 will make the earth more green. Nobody knows what will happen at this point - we can only speculate as to the long term effects of increasing CO2 in the atmosphere. &lt;br /&gt;
&lt;br /&gt;
The open source microfactory is intended to produce an entire technosphere from local resources, pushing the limits of what can be done:&lt;br /&gt;
&lt;br /&gt;
Fig. Open Source Microfactory cyclic material flows can be based on local resources. Metals, bioplastics, ceramics, PV cells, concrete, carbon, hydrogen, glass, rubber, fuels, food, construction materials, and many other chemicals can be produced from local abundance.&lt;br /&gt;
&lt;br /&gt;
If it is indeed that PV cells can be made from local sand, and aluminum from clay - and everything else as noted - then we have truly stepped into a world of post-scarcity. At the point where material production is guaranteed, it may be possible for people to evolve full time - without being held back by mere survival. That is the essence of society that OSE intends to create - one in which material needs are not in the way of human evolution.&lt;br /&gt;
&lt;br /&gt;
For any other processes of industry - the Open Source Microfactory can provide. If you can make buildings, glass, metal, and plastics + other materials - you can build anything. Advanced processes such as chemical plants or semiconductor fabs - are nothing but buildings, metal vessels, motors, vacuum pumps, and a few other basics - and from there spews out any product - in a nutshell. This does not even involve the nanotech of molecular manipulation - where it is deemed that in the future we will be able to synthesize substances by moving atoms directly - without regard for chemical reactivity as we know it today. Yet we do not invoke the Technological Singularity as a prerequisite for meeting all human needs.&lt;br /&gt;
&lt;br /&gt;
Let’s move to the specific tools in the Open Source Microfactory:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
And &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Fig. Tools of the Open Source Microfactory. They include everything needed to produce precision metal parts starting from scrap metals, glass, bioplastics, and even semiconductors for solar cells. &lt;br /&gt;
&lt;br /&gt;
==Universal Axis==&lt;br /&gt;
&lt;br /&gt;
Six of the Open Source Microfactory tools are based on the Universal Axis. The Universal Axis is a modular, and scalable CNC axis which can be used to create cartesian CNC machines. The core of the axis design is belt drive and linear motion rods where carriages are pulled on the rods. The system is scalable to any size and number of axes, including rotary axes. The system uses a combination of 3D printed parts, metal plates, and belt-driven shafts. Applications include 3D printers, CNC torch tables, heavy duty CNC machines, and many other production machines.&lt;br /&gt;
&lt;br /&gt;
We intend to use the 5/16”, 1”, and 2” versions for 3D printers, CNC torch tables, and heavy duty CNC machines - which are among the key machines that can be built with the system - though a variant of any size and shape can be designed.&lt;br /&gt;
&lt;br /&gt;
Fig. The universal axis comes in 5/16”, 1”, and 2” variations, and is based on belt drive, though a screw and nut system can also be used as a drive. Various tool heads can be attached. Non-contact tool heads are attached magnetically, such as the laser cutter and 3D printer. Rotary attachments can even be used for 3D scanning or indexing.&lt;br /&gt;
&lt;br /&gt;
For heavy duty applications, the plastic plates may be reinforced with steel plates - making a steel-plastic composite that has the required strength - while being easy to produce because the complex geometry is 3D printed. The metal plates themselves can be CNC cut using the CNC torch table. This allows for the lowest cost route - the 2” bushings capable of 8000 lb force on these axes currently cost only $9.41 at McMaster Carr.&lt;br /&gt;
&lt;br /&gt;
Fig. Metal-plastic Universal Axis System.&lt;br /&gt;
&lt;br /&gt;
The power of the universal axis lies in its flexibility. The same design of the drive system can be used to make an unlimited range of fabrication machines, putting the manufacturing process completely in the hands of anyone - without high barriers to entry. This is aimed at the Open Source Microfactory in every town, where our goal is to distribute at least 10,000 of these open source microfactories around the world, each generating at least $100,000 of net revenue per year. Once production returns to communities, we expect that taxes will go down as communities once again become responsible for their own prosperity.&lt;br /&gt;
&lt;br /&gt;
==The 3D Printer, Bioplastic Extruder, 3D Scanner==&lt;br /&gt;
&lt;br /&gt;
The 3D printer is a machine with diverse applications. Essentially, the technosphere is made from plastics, ceramics, and metals. 3D printers can print with all of these, and are as such ubiquitously applicable to manufacturing of all sorts. Currently, it is easy to print with all kind of plastic, including rubber for printing tires and polycarbonate for printing glazing. It is likewise easy to print ceramics - by printing clay and then baking it. Here we can produce ceramic cookware or clay parts such as insulators or building bricks. If the clay contains a large fraction of glass or metal - then upon kilning - 3D printed glass and metal objects can be printed as well. Metal printing can also happen via a MIG or TIG welder as the working toolhead - where large metal structures can be printed additively like this. If we go a step up to lasers - we can do selective laser sintering of any kind of powder - from plastic, to ceramic, to metal. Extremely strong, precise metal parts can be created this way - such that for example the rocket engine for Elon Musks’s SpaceX rockets has been 3D printed.&lt;br /&gt;
&lt;br /&gt;
Fig. Different applications of 3D printing: plastic, rubber, glass, metal, ceramic, and housing.&lt;br /&gt;
&lt;br /&gt;
Carbon fiber or metal fibers can also be embedded in plastic 3D prints to make the parts as strong as aluminum. 3D printing can also print ceramic molds which can then be used for casting directly into these molds - using either molten metal from an induction furnace or a MIG weld right into the metal form.&lt;br /&gt;
&lt;br /&gt;
Fig. Apparatus for automated metal casting using 3D printing of molds + induction heating of melt to fill the molds.&lt;br /&gt;
&lt;br /&gt;
Currently - open source printing includes  plastic + rubber 3D printing, welder 3D printing, clay printing for ceramics, clay-metal 3D printing for metals, selective laser sintering of plastics, and 3D priting of concrete or clay buildings. With a little bit of work,  the full printing with metal or glass using selective laser sintering can be developed by using off-the-shelf technologies. An 80W laser tube like in the Laser Cutter + shielding gas allows for selective laser sintering of off-shelf metal powders. http://opensourceecology.org/wiki/Metal_Selective_Layer_Sintering#Literature &lt;br /&gt;
&lt;br /&gt;
Fig. If metal powder is available (it is, such as iron at $1/lb) - then we can use a laser to fuse a powder bed to complex 3D objcts that cannot be produced in any other way.&lt;br /&gt;
&lt;br /&gt;
The world of 3D printing is in its infancy - and this is definitely worth refining to achieve full 3D printability in any material. Perfecting all of the above 3D printing can go far towards local production of just about anything.&lt;br /&gt;
&lt;br /&gt;
==Bioplastic Extruder==&lt;br /&gt;
&lt;br /&gt;
The Bioplastic Extruder is part of a system that enables the production of biodegradeable bioplastics from natural feedstocks such as cellulose or sugars. The system includes 3D printing filament production as well as direct extrusion of useful parts.  &lt;br /&gt;
&lt;br /&gt;
Four main aspects are involved in the Bioplastic Extruder System. First, a bioplastic reactor is used to make bioplastic from abundant biological feedstocks such as cellulose, sugar, or starch. Second - once the plastic is produced - or is available from the waste stream - it can be extruded with the Bioplastic Extruder to make 3D printing filament. Third, the 3D printing filament is then used directly in 3D printers to make useful objects. Fourth, other useful products can be made with the extruder: plastic lumber, which can be made from recycled plastic and sawdust. This could be a great way to recycle plastics into durable construction materials. Other useful profiles - such as tubing and glazing panels - can also be produced with the bioplastic extruder. Thus, the bioplastic extruder per se can be used for 2 main purposes: making 3D printing filament as an intermiediate feedstock for 3D printers - or extruding useful products directly.&lt;br /&gt;
&lt;br /&gt;
Fig. The bioplastic production system of the GVCS consists of bioplastic synthesis followed by extrusion to produce 3D printing filament, tubing, sheets, or plastic lumber. 3D printing filament can be used for 3D printing. Thermoplastic elastomers - or rubber - can also be printed.&lt;br /&gt;
&lt;br /&gt;
There are 3 types of bioplastics - those derived from: (1) petroleum and biodegradeable; (2) biomass and biodegradeable; and (3) biomass and non-biodegradeable. OSE is most interested in bio-based, biodegradeable bioplastics, as the feedstocks are most widely available and can be produced ecologically anywhere in the world. &lt;br /&gt;
&lt;br /&gt;
The OSE bioplastic system allows for local recycling such that the plastic never ends up in the landfill - but is either reused or recycled. By eliminating plastic waste and turning it into valuable products, wealth can be multiplied. Also, we can clean up the environment by reusing plastics - which can otherwise persist in the environment for 1000 years. Such recycling also reduces the need for petroleum - the typical feedstock of plastics.&lt;br /&gt;
&lt;br /&gt;
Bioplastics derived from biomass that are non-biodegradeable can be produced from petroleum substitutes. Petroleum can be replaced with charcoal. As such, any plastic typically derived from petroleum can also be produced from renewable, plant-derived charcoal. In the OSE system, plant matter is pelletized, then burned partially for space heating or process heat - with the byproduct being the important charcoal feedstock. If one is interested in replacing petroleum-derived chemicals - charcoal is first burned in a gasifier to produce CO and H2 - just as the gasifier fuels regular engines with CO and H2 - a combustible mixture. Instead of being burned in an engine as a renewable fuel, these molecules can combine under heat and pressure and an iron catalyst to produce long hydrocarbon chains and water. The long chains are alkanes - the typical long-chain molecules of -[CH2]- found in petroleum. This conversion process is known as Fischer-Tropsch synthesis, and is important from the abundance mindset - in that all products than now come from coal and petroleum can be made more ecologically - from plants. https://en.wikipedia.org/wiki/Fischer%E2%80%93Tropsch_process  &lt;br /&gt;
&lt;br /&gt;
Fig. The circular economy of OSE is based on wood - to make charcoal, paper, bioplastic, rubber, and fuel.&lt;br /&gt;
&lt;br /&gt;
Cellulose acetate is a bioplastic that is easily made from the most abundant organic polymer in the world - cellulose. It can be made readily from trees. Did you know that wood fibers can be converted to this bioplastic by reacting these fibers - with glacial acetic acid? The product is 3D&lt;br /&gt;
&lt;br /&gt;
printable.http://www.designforcraft.com/new-materials-for-3d-printing-cellulose-acetate/  You can make windows with it.http://nvlpubs.nist.gov/nistpubs/jres/19/jresv19n4p367_A1b.pdf  Instead of trees, one can use any source of cellulose - paper, cotton, straw, or other cellulose materials. &lt;br /&gt;
&lt;br /&gt;
Straw and wood are thus very important in the overall product ecology for making fuel pellets, insulation for the Seed Eco-Home (with borax), strawboard, charcoal, paper,  steel (charcoal with iron ore), and bioplastics.&lt;br /&gt;
&lt;br /&gt;
Polylactic Acid, or PLA, is the most popular bioplastic used in 3D printing. It can be derived from bacterial fermentation of sugar - and is thus an accessible technology within the GVCS.&lt;br /&gt;
&lt;br /&gt;
Polyhydroxyalkanoate (PHA) or polyhydroxybutyrate (PHB) bioplastic polyesters are considered the best candidates to replace the current petroleum-based plastics due to their durability in use and wide spectrum of properties. https://www.intechopen.com/books/biotechnology-of-biopolymers/conversion-of-biomass-into-bioplastics-and-their-potential-environmental-impacts  They are made by bacteria from sugar or starch at an efficiency of up to 80% of bacterial cell mass.https://www.intechopen.com/books/biotechnology-of-biopolymers/conversion-of-biomass-into-bioplastics-and-their-potential-environmental-impacts  Some PHAs are elastomers. Thus - it is realistic to include rubber production for tires - from sugar or starch - within the industrial ecology of the GVCS. Unlike latex resin from dandelion roots - which can be used to produce thermoset plastics - PHA rubber is thermoplastic, so it can be recycled easily. Both PHA rubber and dandelion root rubber can be grown anywhere - thus removing the strategic importance of tropical rubber tree plantations. It appears that PHA rubber is more viable from the decentralization perspective. Wood, broken with acid to simpler sugars - can also be used a feedstock for PHA - thus making PHA rubber production possible anywhere in the world. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4964529/   However, woody crop can compete with food crops - so we once again emphasize perennial polycultures as ways to produce food, fuel, and fiber. With perennials, it is also easier to use degraded lands, which can be regenerated back to fertility and health when annual crops are removed from the equation.&lt;br /&gt;
&lt;br /&gt;
In addition to sugar and cellulose, starch from common sources such as potatoes or corn can be polymerized readily in the kitchen. For example, mixing vinegar and glycerine with the starch makes a bioplastic.http://opensourceecology.org/wiki/Starch_Bioplastic   This is the easiest route  that can be used for 3D printing&lt;br /&gt;
&lt;br /&gt;
The bioplastic extruder has 2 main functions: one is to perform extrusions directly - or to produce intermediate 3D printer filament which is then used to 3D print final objects. For the latter, we are currently building upon two open source projects working on plastic extruders: the Lyman Filament Extruder,http://opensourceecology.org/wiki/Lyman_Filament_Extruder  and the Thunderhead Filament Extruder from Tech For Trade.http://opensourceecology.org/wiki/TechforTrade  These are simple versions of plastic extruders - which if scaled up and made more robust - can produce not only 3D printing filament, but larger extrusions.&lt;br /&gt;
&lt;br /&gt;
==3D Scanner==&lt;br /&gt;
&lt;br /&gt;
The 3D scanner allows for scanning of 3D objects to produce Computer Aided Design (CAD) models for reverse engineering. This is very useful - as we can take existing parts and digitize them for use as editable CAD models. A single camera can be used for photogrammetry, which is a computational technique for converting a set of pictures of an object taken from multiple angles into a 3D object.http://opensourceecology.org/wiki/Open_Source_Photogrammetry There is a number of open source programs that can do this. A 3D digital object can also be generated using multiple cameras, laser beams, or other light sources reflected from an object. As the simplest route, OSE  will build on existing work to develop the toolchain and procedure for photogrammetry - as that requires no hardware outside of a simple camera and a computer to process the images. If markers are used on objects, accurate CAD can be generated with proper dimensions. &lt;br /&gt;
&lt;br /&gt;
It gets more interesting: we can 3D scan internal features, too. This is known as industrial Computed Tomography (CAT) - essentially - a CAT scan for metal objects. By using an x-ray or gamma ray source - and then photographing an image - we can build a low-cost DIY CAT scanner.https://www.youtube.com/watch?time_continue=25&amp;amp;v=hF3V-GHiJ78  http://www.tricorderproject.org/blog/tag/openct/  Combined with an open source code base for image processing  from CERN, 3D industrial tomography scans can be obtained.https://home.cern/cern-people/updates/2016/09/new-open-source-medical-imaging-tools  &lt;br /&gt;
&lt;br /&gt;
==CNC Circuit Mill + Small Laser Cutter==&lt;br /&gt;
&lt;br /&gt;
We have already prototyped a circuit mill - the D3D CNC Circuit Mill.http://opensourceecology.org/wiki/D3D_CNC_Circuit_Mill  This shows a great example of the Unversal CNC axis modularity - where we have used the same motion system as in the 3D printer - but now strengthened the motion system by doubling the x axis to hold a small router. While the 3D printer is a non-contact manufacturing method - the circuit mill requires that the axes withstand contact forces of the milling operation. The strong, steel space frame of the D3D platform can handle these forces.&lt;br /&gt;
&lt;br /&gt;
Furthermore, other tool heads can be used on the Universal Axis. One useful example is a small 4W laser cutter, which cut up to ¼” plywood for prototyping purposes.&lt;br /&gt;
&lt;br /&gt;
Fig. The OSE CNC circuit mill and example circuits produced. The Router Tool Head is one of many tool heads that can be used on the Universal Axis system. A small laser is another, and can be retrofitted readily. The laser cutter toolhead allows for cutting cardboard for rapid prototyping. (4-picture - mill+product, laser+product)&lt;br /&gt;
&lt;br /&gt;
Prototyping with a laser cutter is important to the GVCS because the laser cutter can simulate the cutting that is typically done with a CNC torch table. Just like the CNC torch table typically cuts ½” thick flat parts out of sheet steel - the small laser cutter can cut parts out of paper stock. These parts can then be glued or fit together - just like the CNC-torch-cut metal parts are welded to make real-life 3D machines such as the CEB Press.&lt;br /&gt;
&lt;br /&gt;
Fig. Flat metal is used to generate 3D objects by welding. We thus use 2D cutting to create 3D objects.&lt;br /&gt;
&lt;br /&gt;
An open source project for a larger laser cutter - the 100W Lasersaur - is already well-developed. We can use this platform to build upon as well, to reduce cost from its current $7k to something more on the scale of $3k for a large format laser cutter. The Universal Axis could be applied here, such that only the laser system ($2000) remains as a significant cost - and the rest of the system is ($1000). This would be another great application of the Universal Axis to show its flexibility.&lt;br /&gt;
&lt;br /&gt;
Another useful example of a practical tool-head is a ceramic 3D printer head - which is an extruder for clay materials that can be fired to make functional ceramics. Examples of very useful ceramics are insulators and pottery - especially stovetop cookware made of flameware clay - which can replace commercial cookware and provide artistry in the open source Seed Eco-Home kitchen.&lt;br /&gt;
&lt;br /&gt;
Fig. The ceramic print head allows for the production of practical objects such as pots and pans for cooking, bringing artistry back into the kitchen.&lt;br /&gt;
&lt;br /&gt;
Collaborative Prototyping + Model Kits + Product Ideas + The Open Source Everything Store&lt;br /&gt;
&lt;br /&gt;
With access to the OSE Developer Kit - 3D printer, CNC Circuit Mill, and Laser Cutter - all as different tool heads on the same Universal Axis system - collaborators access a powerful capacity to prototype the larger machines of OSE. Using these tools, accurate scale models can be built. This can extend the collaboration capacity on OSE machine development significantly. There are 4 major ways that collaborative prototyping can be done using the 3-in-1 Universal Axis machine. &lt;br /&gt;
&lt;br /&gt;
First, there is collaboration is CAD verification. Computer Aided Design (CAD) is used in the OSE design process in order to save countless hours during the build. In a proper design process, it is easier to design in virtual CAD - and figure out how everything fits together - rather than going straight to a build and having to fit everything on the fly. The ability to model accurately in CAD is the power that allows OSE to do builds on the scale of a day - as opposed to weeks. However - this works only if the CAD is accurate, because if the CAD drafting is not accurate, it may be impossible to build a machine. CAD quality depends on the skill of the draftsperson. For this reason, it is important to verify the CAD as one of the steps that takes place prior to a build. If mistakes are not caught prior to the build, time and materials are wasted, people can get frustrated, and schedules are delayed.&lt;br /&gt;
&lt;br /&gt;
How do we guarantee that a machine can be built as drafted? With an accurate scale model. First, we must make sure that the CAD of individual parts is correct. This can be assured when accurate CAD files are available - whether the files are generated from measurements, provided by manufacturers, or 3D scanned with the open source 3D scanner. Second, we can verify the actual buildability. This can be done by laser cutting from paper the parts that would be CNC Cut from steel, and then 3D printing the components that we would otherwise get off-the-shelf. For the 3D printing - it is critical that we print every single part - up to bolts and nuts - so the entire assembly we can verify every single step of the build.&lt;br /&gt;
&lt;br /&gt;
This leads to the second use of collaborative prototyping - producing build instructional manuals and videos using the scale models. This allows contributors all over the world to produce meaningful content - without requiring that the contributors have access to a workshop. Since qulaity intstructionals production requires as much effort as the design work - this is another way to contribute to a large, parallel development effort.&lt;br /&gt;
&lt;br /&gt;
The third route to collaborative prototyping is the production of Model Kits for actual products. For example, the Seed Eco-Home lends itself very well for such modeling. Another company, Arckit (ref), is a good model for how we can design the model kit for the OSE’s collaboration with the Open Building Institute.&lt;br /&gt;
&lt;br /&gt;
Fig. Arckit is a great example for modeling. In the OBI case, the models correspond to real building panels and real build procedures. This makes the OBI Architecture Kit a tangible way for people to get involved in meaningful design of future house models.&lt;br /&gt;
&lt;br /&gt;
The OBI Architecture Kit lends itself well to 3D printing as well as laser cutting. 3D printed parts would snap together like Lego blocks.&lt;br /&gt;
&lt;br /&gt;
Another model kit that would be very useful to GVCS prototyping is the Machine Build Kit -  a kit for producing tractors, heavy equipment, and other automated machines. Combined with the OBI Arch Kit for buildings - this would produce the Civiliation Model Kit. The concept for the Machine Build Bit is a mixture of Lego Mindstorms, MakeBlock, Erector Set, Capsela, Box Beam Sourcebook, and Solar Micro Power Cube (all refs) - so that the system can run on solar power. The value proposition is that the kit would once again be based on real buildable parts - thus extending its use from childsplay to real design work.&lt;br /&gt;
&lt;br /&gt;
The OSE Developer Kit + Model Kits pave the way for the 4th route to collaborative prototyping - that of developing open source enterprise. These 2 kits are products in themselves - and can be used as the basis for collaborative business development of distributive enterprise (ref). The concept here revolves around reaching the $1T tipping point for the open source economy - the point at which mainstream adoption of open source economics is likely ($1T is calculated as the 10% tipping point at which viral adoption of open source economics can occur. This coincides with the next Enlightenment of humanity - see Tipping Point on the wiki - http://opensourceecology.org/wiki/The_Tipping_Point  ). This is as large as the combined revenue of Apple ($229B), Google ($79B), FB ($41B), Amazon ($178B), and Walmart ($486B) combined (Microsoft ($90B) - not includes so total is $1T.) - the latter being the single largest corporation in the world.&lt;br /&gt;
&lt;br /&gt;
OSE’s distributive enterprise approach to the tipping point is distributive. The core of OSE’s economic theory is that, by definition, a distributive enterprise serves its customers more effectively than any proprietary enterprise. Thus, a DE has a high likelihood of deposing the corporation http://opensourceecology.org/wiki/The_Corporation  as the dominant societal institution, replacing it with the next phase of the human economy - the open source economy. The transition is in our view likely - because the goal of a distributive enterprise is to produce free enterprise - defined as  distributing wealth most equitably. Current economic paradigms do not internalize distribution in their economic models. The next economy is achievable via full cost accounting and zero competitive waste, thereby achieving zero marginal cost (ref ZMCS). This proposition is simple to grasp, but most challenging to execute. We are not interested in DE as an ideology - but as a pragmatic proposition that simply meets needs more effectively - in an integrated sense -  than current models.&lt;br /&gt;
&lt;br /&gt;
The ask for distributive enterprise is to create the Open Source Everything Store - a networked and collaborative store based on Open Source Microfactories. That is - for people to collaborate on open source product development as a massive parallel effort. Decentralized, distributed, networked production is not a new idea - many people love and claim the idea as their own. To date no successful, economically-viable implementation exists, and certainly not open source. There were many attempts, from the FabLab, Local Motors, 1000 Garages, Ponoko - but none are both distributed and open source. The FabLab is a distributed microfactory concept, but none of its machines are currently open source. FabLabs are are externally funded, and none are used to run a successful business. Local Motors works on distributed production, but their designs and microfactory tools are not open source. 1000 Garages appears stalled. Ponoko and many operations like Ponoko are available. They are successful enterprises, but they do not use open source production tools or software. None of these projects provide open source enterprise information. Perhaps the best examples are 2: first, Lulzbot, which shares its machine designs and enterprise blueprints (blog post from 2014 visit, google Distributive Enterprise) - which makes it a fully open source hardware company - but it has a centralized business model. Second, there is the poster child RepRap project - which is the design/collaboration repository for open source 3D printers. RepRap is responsible for producing most of the consumer 3D printing industry’s companies - both open source and proprietary. (ref) However, RepRap in itself does not have a revenue model. Our own work is also based on the RepRap - it’s the basis that saved us hundreds of development hours - as we could simply build upon their designs. We do have a successfully-demonstrated revenue model of ongoing Extreme Manufacturing workshops.&lt;br /&gt;
&lt;br /&gt;
For The Open Source Everything Store (TOSES), any product developed must include open source blueprints, as well as open source enterprise documentation. Assets such as marketing materials, revenue models, business plans, projections, and entrepreneurship training - among others - must be included to facilitate startup by others. For successful startup - the enterprises themselves must be tested and proven. Thus, case studies of projections, actual revenue, and growth must be included. &lt;br /&gt;
&lt;br /&gt;
With as small an infrastructure as a Personal Microfactory with 3D printing, the CNC circuit mill, laser cutter, filament extruder, and off-shelf components - production of many valuable products can be distributed far and wide. Moreover, open design allows for extended product lifetime - as parts can be upgraded, modifications can be 3D printed, and breakages fixed with readily-accessible parts.  The success of TOSES  revolves around a massive parallel open source product development process - resulting in best-in-class products. These products are then produced by distributed players. Thus, a networked effort could reach substantial distributed production - and distributed sales volumes on the scale of Amazon. &lt;br /&gt;
&lt;br /&gt;
Our claim is that Distributive Enterprise has a good chance of succeeding because of its distributive nature. The cost structure of distributive development is efficient - as it relies on an open source process. We are assuming here that the zero marginal cost prediction - that everything trends to zero marginal cost - which is the competitive advantage of TOSES. However, zereo marginal cost is inherently impossible within the current system. The profit motive of the corporation prevents zero marginal cost, and leads to a permanent inefficiency in human economics. This can be resolved only by a transition away from the traditional corporate IPO form (ref). This is the reason why OSE proposes that a transition to the open source economy is inevitable. However, leading economic theorists such as George Gilder claim that human constructs are not inevitable - they have to be created. Thus, it remains up to human will to decide whether we would like to implement true-cost accounting to transition to the open source economy.&lt;br /&gt;
&lt;br /&gt;
The choice is up to us, and as such we are working on the DE model. Once open source product and enterprise blueprints are available - it means that everyone has access to them. This indicates that efficient production can be distributed into a networked form, which can gobble up Amazon and Walmart. Such a transition to the true-cost accounting economy is the promise of open source economics.&lt;br /&gt;
&lt;br /&gt;
In practice, this requires that open source microfactories, as well as open source materials production facilities - are distributed far and wide. These take abundant natural resources and convert them to a modern standard of living in a distributed way. People can produce with their personal microfactories. Using the 3D printer, circuit mill, laser cutter, and filament extruder - and off-shelf components - people can produce many household goods, electronic gadgets, toys, tools, kitchenware, small appliances, lab equipment (ref), and many others.  The size of the plastic industry alone is $2T - and the size of the injection molding industry is about $100B. Between vaccuum cleaners ($1B), consumer 3D printers ($1B),  cordless drills ($1B in the USA alone), drones, phones, cameras - the market size for those goods is on the order of hundreds of billions of dollars worldwide.  The current limit is 20% of GDP - the manufacturing sector of the economy - or about $16T.&lt;br /&gt;
&lt;br /&gt;
The centralized factory can become obsolete, and many parts of global resource flows can become localized. Specifically - as resource constraints to longer fuel resource conflicts and poverty - humans as a whole have - for the first time in world history - a chance for collective evolution. That simply means that the leading preoccupation transitions from making a living, surviving, or paying off debt - to thriving. This means that the multidisciplinary genius will become much more common - as society reaches a new level. An Einstein could be born every minute. (That makes it 1/250 - or 0.4% of the population.) This means that we transcend William Gibson’s — &#039;The future is already here – it&#039;s just not evenly distributed”. This means that most people will gain access to significant improvement in their quality of life. But this is also not a state of coerced equality as in communism - there will always be outliers who are more ambitious or skilled. But all have a good oportunity to thrive. &lt;br /&gt;
&lt;br /&gt;
CNC Torch and Larger Machines: Heavy Duty CNC Machining&lt;br /&gt;
&lt;br /&gt;
==CNC Torch Table==&lt;br /&gt;
&lt;br /&gt;
The universal axis can handle much larger forces - up to one thousand pounds - when it is scaled up. The universal axis has aleady been used with the 3D Printer and the CNC circuit mill. http://opensourceecology.org/wiki/Universal_CNC_Axis   &lt;br /&gt;
&lt;br /&gt;
We have already built a prototype of the CNC torch table using the Universal Axis, scaled up to a 2x3 meter working area:&lt;br /&gt;
&lt;br /&gt;
Fig: CNC Torch Table build workshop results. (https://www.facebook.com/marcin.jakubowski.378/posts/10213076897374250) &lt;br /&gt;
&lt;br /&gt;
The CNC Torch Table is near release status, and it will be the critical machine used in digital fabrication. The CNC Torch table will be used to cut all metal from flat sheets, which are then welded into 3D machines such as the brick press and tractor. The CNC Torch Table will also be used for cutting holes in 4” square tubing - which is our characteristic life-size erector set design.&lt;br /&gt;
&lt;br /&gt;
Typically, acetylene is used as a cutting gas. In the OSE case, the CNC torch table integrates with the oxyhydrogen production - where water is split into hydrogen and oxygen using electrolysis. These hydrogen and oxygen gases are used as the cutting gases. Oxyhydrogen cutting has been in use prior to the discovery of oxyacetylene cutting in 1903 https://en.wikipedia.org/wiki/Oxy-fuel_welding_and_cutting  - and was preferred for 2x the cutting speed with thick metal. Currently, oxyhydrogen is use whenever a clean cut is required. Otherwise, the gas is 2x as expensive as acetylene. The advantages of hydrogen are the ability to cut aluminum and stainless steel, which acetylene cannot do. Furthermore, if the open source oxyhydrogen generator is used with PV electricity at 1.5 cents per kWhr, then the cost of the gas should go down to about 5x lower than acetylene. Given these advantages, it is interesting to see that oxyhydrogen cutting is not used more commonly in the workshop. The apparent reason for this appears to be the lower price of fossil-fuel derived acetylene. Off-shelf on-demand oxyhydrogen generators appear to be expensive, so they would benefit greatly from being open-sourced. https://www.alibaba.com/product-detail/Gas-generation-equipment-for-oxgen-hydrogen_1950398042.html?spm=a2700.7724838.2017115.380.1b0840b43VI2AU  Hydrogen generators which can produce enough gas for cutting ½” steel are  are available for around $300, not including power supply. http://opensourceecology.org/wiki/Oxyhydrogen_Generator_Cost &lt;br /&gt;
&lt;br /&gt;
The OSE CNC torch table system includes a water bed to minimize smoke and prevent steel from warping while cutting, automatic height control which follows the surface of the metal for optimal cutting, an automatic ignitor, automatic gas control, open source controller, and open source controller software. Each of these piecces has been tested separately, and now we are putting the entire system together to a product that from 2018 onwards will be used to cut all steel for OSE in house. We cut steel for frames of the 3D printer, metal for the brick press, tractor, and just about every other GVCS tool.&lt;br /&gt;
&lt;br /&gt;
==Heavy Duty CNC Multimachine==&lt;br /&gt;
&lt;br /&gt;
The CNC Multimachine is a mill, drill, lathe and other tools in one machine, designed for modularity and flexibility, including rotary indexing and a grinding attachments. It can be used to produce engines and hydraulic motors, threaded parts such as bolts and pipe threads, as well as myriad other parts. The lathe has historically been the cornerstone of precision machining, and is a critical tool in civilization.  It is also another application of the OSE Universal Axis system - using the 2” rod size.&lt;br /&gt;
&lt;br /&gt;
Two other GVCS machines - the induction furnace which melts scrap metal to make virgin steel -  and the Mill which makes Rods and Wire - provide feedstocks for the CNC Multimachine.&lt;br /&gt;
&lt;br /&gt;
Fig. The 2” Universal axis can produce parts with accuracy of 10 microns, based on the deflection of 2” rods with 200 lb of force. This image shows the size comparison between the 2” version - and the 1” and 5/16” versions. The belt drive system can be identical to the smaller machines.&lt;br /&gt;
&lt;br /&gt;
We are interested in developing a core set of modules for a heavy duty machine - including mill, drill and lathe, with rotary and angle tables, plus capacity to function as a screw machine for making threads and bolts. We also include internal threads splines. &lt;br /&gt;
&lt;br /&gt;
Just like with the OBI Arch Kit (make sure reference is correct to rapid prototyping above), the Multimachine Construction Set will allow for modeling with 3D printed parts, which will correspond directly to real life - and thus serve as an educational kit and product. Together with the Multimachine Design Guide and FreeCAD workbench, people will be enabled to build their own multimachines and screw machines.&lt;br /&gt;
&lt;br /&gt;
For the 2” universal axis system, the practical limit is 400 lb of tool force with 0.001 precision and GT2 belt drive. For higher tooling forces, we must use lead screws instead of belts.&lt;br /&gt;
&lt;br /&gt;
The goal of the CNC multimachine is to produce electric motors, hydraulic motors, engines, cylinders, and valve blocks, among others. With a grinder attachment, the idea is to be able to achieve high precision, down to 0.0005, which is the positioning accuracy of the stepper motors at 16 microstepping and 1” GT2 pulleys.&lt;br /&gt;
&lt;br /&gt;
Using the Universal Axis, CNC linear motion control, and CNC rotary chuck control - we can get a wide array of functionality of a screw machine for making various precision parts. With a surface grinder, we can get precision parts down to 25 microns of tolerance. If we build a precision CNC surface grinder, then we can achieve up to 1 micron accuracy for making air bearings.https://www.youtube.com/watch?v=sFrVdoOhu1Q  Air bearings open the possibility of lubrication-free engines and high pressure pumps for storing hydrogen and a prerequisite for certain clean-room semiconductor manufacturing.&lt;br /&gt;
&lt;br /&gt;
==Robotic Arm - trainable for welding + 3D printing==&lt;br /&gt;
&lt;br /&gt;
The robotic arm is a powerful manufacturing tool as it is can move almost as flexibly as a human arm - but with increased precision and strength. Practical tasks that a robotic arm can accomplish depend on the end effector or tool that the arm is holding. For the GVCS, two good applications include automated welding and 3D metal printing using a MIG or TIG welder.&lt;br /&gt;
&lt;br /&gt;
Fig. Robotic welding - [nice pic] is useful for high quality welding to assist the open source renaissance woman. Spot welding or wire welding can be used.&lt;br /&gt;
&lt;br /&gt;
A useful application of robotic arms emerges from trainable robotic arms. Trainable robotic arms are arms which a human operator can train to move as needed. This eliminates complex programming tasks, making robotic collaborators accessible to the general public. An open source software platform already exists for robotic arms in the Robotic Operating System (ROS) project, including trainability.http://moveit.ros.org/  - such that the open source trainable industrial robot is around the corner by building on existing prior art. &lt;br /&gt;
&lt;br /&gt;
==Induction Furnace==&lt;br /&gt;
&lt;br /&gt;
An induction furnace is a device use to melt metal.  Metal can then be recycled - from scrap to useful stock. The advantage of the induction furnace over any other means of melting metal is a clean, energy-efficient and well-controllable melting process. In a typical induction furnace, a water-cooled copper coil with alternating current induces a current in a crucible of metal - hence the name Induction furnace - and that current heats up and melts the metal. Due to the heat being generated within the work piece, energy transfer is extremely efficient.&lt;br /&gt;
&lt;br /&gt;
Fig. In an induction furnace&lt;br /&gt;
&lt;br /&gt;
The induction furnace brings us from the stone and wood age - when stone and wood were the most common materials for making houses and machines - into the iron age - which is synonymous with the industrial age and modern civilization.  &lt;br /&gt;
&lt;br /&gt;
It may be said that modern civilization has culminated with the production of ball bearings. Bearings are a critical component that allows for engines, turbines of modern power to work - and precision machines that use precision ball bearings are used to manufacture these machine. Finally,  vacuum pumps and precision instruments - necessary in semiconductor manufacturing - depend on the use of bearings. As such, the information age today also relies on ball bearings - a combination of material science and precision manufacturing.&lt;br /&gt;
&lt;br /&gt;
==Metal Rolling, Rod &amp;amp; Wire Mill==&lt;br /&gt;
The induction furnace can be used in metal casting, where round rods or billets are cast and then used as feedstocks for metal rolling.&lt;br /&gt;
&lt;br /&gt;
Metal rolling uses rolling dies to shape metal into various profiles, from flat, to round, to angled. &lt;br /&gt;
&lt;br /&gt;
Fig. Metal rolling uses dies of various shapes to produce final stell shapes.&lt;br /&gt;
&lt;br /&gt;
Rolling of thin rounds - or rods - around dies and pulleys - is used to elongate and thin the rounds results in wire - a fundamental building block of civilization. Wire is used for house electrical wiring, suspension,  or fencing.&lt;br /&gt;
&lt;br /&gt;
Fig. A wire drawing machine starts from rod and stretches it to wire through a number of dies. The modular open source version can take rod and turn it into wire of any diameter.&lt;br /&gt;
&lt;br /&gt;
Metal rolling that occurs above the crystallization temperature (700C) is called hot rolling - and it takes less energy to do so as the metal is pliable. Cold rolling occurs at room temperature, and therefore requires more energy to deform the metal - but it also provides more accurate dimensions in the metal.&lt;br /&gt;
 &lt;br /&gt;
==Forging, Ironworker==&lt;br /&gt;
&lt;br /&gt;
The press forge is a heavy duty press than can be used to squeeze metal like butter. When metal is hot, it can be deformed into useful shapes by using a die. Bolt heads are made this way.&lt;br /&gt;
&lt;br /&gt;
Forges can take the form of press, drop, or roll rolling - preferably using the induction furnace for efficient forging. Cold forging may also be done, but that requires larger force for a given deformation.&lt;br /&gt;
&lt;br /&gt;
Forging is useful but the disadvantage is using specialized forming shapes or dies. Thus, the preferable route to forging would in many cases be subtractive machining, metal 3D printing,  or welding - as these are general-purpose procedures that do not require custom forms or dies.&lt;br /&gt;
&lt;br /&gt;
Fig. The press forge can shape hot or cold metal like butter.&lt;br /&gt;
&lt;br /&gt;
==Plasma Cutter, Welder==&lt;br /&gt;
&lt;br /&gt;
The plasma cutter, welder, and induction furnace are high-power electronics that use modern technology for efficiency. By using transistors and inverter circuits instead of large transformers, they can be light-weight and low cost - as the cost of power transistors is 10 cents/kW of power handling ability. This means that the simplest welder circuits can cost only a few dollars in electronic components (not counting wiring, structure, and the balance of system) to get industrial welders on the scale of 10kW (500Amps).&lt;br /&gt;
&lt;br /&gt;
Fig. Diagram of a welder. From first principles, a welder includes power handling electronics, wires, a case, cooling fan, and a welding gun with an electrode, and shielding gas for high quality welds.  In the simplest case - a tungsten electrode creates an arc to the metal and melts the metal, without using filler. This is an example of autogenous welding, where no welding rod or wire is required.  Welding is not complicated - the simplest electric arc welder is a 12V battery connected to a welding rod.&lt;br /&gt;
&lt;br /&gt;
A plasma cutter is a transistor-based power electronic device that cuts conductive metals with a plasma - or ionized gas.  The plasma cutter creates ionized air between an electrode and a work piece. The plasma heats the metal. By directing a focused stream of air around that plasma through a nozzle, the heated metal is oxidized and blown away, creating a clean cut. For comparison,  cut quality  in order of improvement is plasma cutting, oxy-fuel, waterjet, and laser cutting.&lt;br /&gt;
&lt;br /&gt;
Fig. Cut width - or kerf - of plasma, oxyfuel, waterjet, and laser cutting.&lt;br /&gt;
&lt;br /&gt;
Both the plasma cutter and welder are similar to each other. They have similar power electronic circuits.  For a welder or plasma cutter, the main difference is in the gun and electrodes. The gun in both cases has a large copper power wire and a gas line for shielding. For the MIG welder, it also has wire feed. The electrode is tungsten for the TIG welder and plasma cutter, and consumable welding wire for the MIG.&lt;br /&gt;
&lt;br /&gt;
More Power Electronics&lt;br /&gt;
&lt;br /&gt;
Is EDM practical? EDM is a high-voltage spark erosion system for cutting thick metals - where a moving wire at 10,000VDC spark-erodes metals as tiny sparks are established between the wire and metal to be cut. This system is insulated&lt;br /&gt;

&lt;br /&gt;
Disclaimer - Graph of completion&lt;br /&gt;
Here we discuss all the tools, but please remember that in Part 1 of the 4 Part Series, many of the machines are still on the drawing board.&lt;br /&gt;
&lt;br /&gt;
=Agriculture=&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
If you eat, you use a Tractor. Maybe not you directly, but the farmer that grew your food. And food is a $8T industry. The GVCS field agriculture machinery that support this $8T industry &amp;lt;ref&amp;gt;https://www.plunkettresearch.com/statistics/Industry-Statistics-Global-Food-Industry-Statistics-and-Market-Size-Overview/&amp;lt;/ref&amp;gt; are:&lt;br /&gt;
&lt;br /&gt;
Fig 1. The Tractor, Microtractor, Microcombine, Universal Seeder, Spader, Hay Cutter, Hay Rake, Baler, and Dairy Milker, and a Bakery Oven are critical tools of the $8T food industry.&lt;br /&gt;
&lt;br /&gt;
==Tractor, MicroTractor, Bulldozer and Power Cubes==&lt;br /&gt;
&lt;br /&gt;
The tractor is a cornerstone of a farm, construction, or other materials production industries. A tractor has the traction to pull things, and to do utility work with variou implements that can be added to a tractor and use the tractor’s mechanical power through a Power Take-off (PTO). As such, the tractor can be a swiss army knife of heavy duty work. For the smaller individual or home scale, we have the MicroTractor in the set, which is a small, walk-behind or ride-on tractor at the 16-32 hp size that can perform many gardening and utility functions and can fit in a smaller areas where a large tractor would be impractical. If we go up in scale - use a stronger frame and at least 64 hp, and add a bulldozer blade to the tractor - then we have a bulldozer.&lt;br /&gt;
&lt;br /&gt;
The tractor is a machine on the scale of 50-320 hp in the GVCS ecosystem, and unlike traditional tractors, we focus on modular power. We currently use small 16 hp engine units at $17/hp (ref), which is the lowest cost way to obtain engine power, while making maintenance very easy. Like in nature where a tree is made of many branches, our tractor is made of many small engine units. This way, the same design pattern can be used in the 16 hp tractor as in the 320 hp tractor. The price for using larger diesel engines is 2-4 times larger.  &amp;lt;ref&amp;gt;http://opensourceecology.org/wiki/Diesel_Engine_Cost &amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
By using the modularity concept, we create our typical construction set approach for heavy machines. For example, if a large tractor frame is fitted with a bulldozer blade - then we don’t require a separate bulldozer in addition to a tractor. This saves a lot of resources - making technology significantly lower cost to maintain. Exploring the limits of modularity, we found that it is much less expensive to scale our machines usig modular and overbuilt parts that make sense both for small and large machines. For example, we can use 4 of our identical track units, each rated for up to 80 hp - Our track unit, for example, allows for a $30k version &amp;lt;ref&amp;gt; http://opensourceecology.org/wiki/Modular_Track_Unit_v18.01&amp;lt;/ref&amp;gt; that matches the traction of a Cat D7 - a sizeable cost savings comprd to a base price of ½ a million. &amp;lt;ref&amp;gt;https://www.caranddriver.com/reviews/caterpillar-d7e-feature-test &amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Fig. Pattern Language for a Tractor - up to automated control.&lt;br /&gt;
&lt;br /&gt;
The key is making it easy and quick to interchange parts - from small parts to large implements. This is a great challenge for advanced industrial design.&lt;br /&gt;
&lt;br /&gt;
Fig. Industrial smaller parallel and trained configuration. OSE machines can be designed like this, but higher flexibility of the OSE platform can allow for an improved configuration.&lt;br /&gt;
&lt;br /&gt;
Fig. The flexibility of a modular OSE tractor. The modular OSE tractor can be built from the same components, but apply to 16 hp or 320 hp machines while using the same over-engineered components such as the ½” thick steel tracks &amp;lt;ref&amp;gt;Current design is rated for  rated for 40 hp per track or 80 hp with double drive, . (ref - do calculations) and 3600 lbs or 7200 of pull each. Thus, a four-tracked machine can have 29,000 lb of pulling force with direct drive using our current 15k in-lb motors.&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
==Spader, Seeder, Bulldozer==&lt;br /&gt;
&lt;br /&gt;
Your food today is grown largely by tractor-driven  tilling and seeding, unless you’re a breatharian. Tillage in the OSE system chooses the spader as a more progressive technology compared to the age-old plow. &lt;br /&gt;
&lt;br /&gt;
Fig. (Image of 1800 steam tractor with 50 bottom plow) &lt;br /&gt;
&lt;br /&gt;
The spader works essentially like  a bunch of shovels moving rapidly - which till soil without crating a hardpan typical of the more common plow. Manufacturers claim that spading uses 40% less fuel than plowing - because a spader can combine tilling, harrowing, and planting in one operation. &amp;lt;ref&amp;gt;https://www.farmax.info/PDF/Magazine-Farmax-EN.pdf &amp;lt;/ref&amp;gt; A plow, which drags through the soil, requires a lot of wheel-to-ground  traction, whereas a spader requires very little - thus avoiding soil compaction. It takes a spader under 9 minutes and 2 gallons of fuel per acre of field - such that feeding Dunbar Village &amp;lt;ref&amp;gt;A village of 200 -  based on Dunbar’s number https://en.wikipedia.org/wiki/Dunbar%27s_number &amp;lt;/ref&amp;gt; would take 6 hours to plant for a whole year of crop &amp;lt;ref&amp;gt;Assuming field crops planted with a seeder, not slips like sweet potatoes. http://opensourceecology.org/wiki/Acres_Needed_to_Feed_Dunbar_Village &amp;lt;/ref&amp;gt;Thus, one day to plant, two days to harvest - and the village has food for the year. &lt;br /&gt;
&lt;br /&gt;
The tractor and universal seeder is an example of how we approach multiple purpose machines. The tractor is a large-size swiss army knife for doing many different tasks. The Universal seeder is designed to plant all types of seed, from alfalfa to wheat, to tubers, and to live plants like sweet potato slips. Modifying the device rapidly is key to this flexibility.&lt;br /&gt;
&lt;br /&gt;
Fig. Swiss army knife tractor concept&lt;br /&gt;
&lt;br /&gt;
The point of using powerful machines wisely is that in the OSE perspective of lifetime growth -  life could become easy so we can focus on evolving as humans. Our experiment involves building a college campus where peole live this. When they graduate, they know how to organize a village to spend 2 hours per day working on survival, and then the rest of their life they pursue their highest ideals.&lt;br /&gt;
&lt;br /&gt;
The experimental village thus requires one farmer who is employed 3 days of the year, assuming the equipment does not break down, and generates 30 acres * $20k/acre of sweet potato, and $5k/acre for 10 acres of wheat if that is turned into bread  - or $650k worth of food for the community with direct marketing. That is $27k/hour if baking is automated - a decent pay, but not like the $25k/minute rate of Warren Buffett &amp;lt;ref&amp;gt;http://www.businessinsider.com/what-warren-buffett-makes-per-hour-2013-12  &amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Of course these are unreasonable figures, but they do represent the idea. The only way that customer acquisition and marketing costs do not ruin such ideals is in the case of direct marketing - where the on-site farmer-scientist provides for a captive audience of the Dunbar village. If each person eats about $2600 per year &amp;lt;ref&amp;gt;https://www.google.com/search?q=average+cost+of+food+per+year&amp;amp;oq=average+cost+of+food+per+year&amp;amp;aqs=chrome..69i57j0l5.7243j1j7&amp;amp;client=ubuntu&amp;amp;sourceid=chrome&amp;amp;ie=UTF-8&amp;lt;/ref&amp;gt;, feeding 150 people would involve revenues of $390k - but that would be a full time job. We will look more carefully at the business model for resident farmer agriculture in the Enterprise chapter.&lt;br /&gt;
&lt;br /&gt;
Now it would take more time to do a diversified operation, but this is shown just as a baseline to see what’s possible in terms of the effort.  Several Ph.D.’s can be granted to develop a diversified, 40 acre subscription farm, using open source equipment and a captive market, or Local Food Nodes as part of a distribution platform.  &amp;lt;ref&amp;gt;https://localfoodnodes.org/&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The OSE project will develop such a food enterprise both for its campuses and for the outside community - once all the farming machines are done, the aquaponic greenhouse production is optimized, and derivative food processing tools are developed.&lt;br /&gt;
&lt;br /&gt;
The open source tractor can be built at a cost of $125/hp at a scale of 80 hp, compared to $370-$1000 for other brands. It is useful to understand the basic cost breakdown based on off-the shelf parts:&lt;br /&gt;
&lt;br /&gt;
Fig. Cost breakdown of a tractor by Frame, engine, hydraulics, control, automation, and balance of system - $125/hp. (p590MJ)&lt;br /&gt;
&lt;br /&gt;
The cost advantage is less visible at the 32 hp MicroTrac, at $160 per hp - though but a comparable mahine like the tracked Toro Ding costs around  $1000/hp (ref).&lt;br /&gt;
&lt;br /&gt;
Fig. Microtrac with tooth bar bucket can till your garden, and provide valuable utility work. It is an indidspensible utility machine for any prosumer.&lt;br /&gt;
&lt;br /&gt;
==Hay Cutter, Rake, Baler==&lt;br /&gt;
&lt;br /&gt;
If farm animals are involved, then you need these. Or if you want to move large quantities of materials, then a bale is a useful form: from a bale of hay, brush, cotton, cardboard, or plastic - bales allow large scale moving of materials. Bales of aluminum cans are likewise useful for melting down in your induction furnace. If you are making fuel pellets from biomass, plastic pellets for making 3D printer filament - you will need a baler to make 1 ton bales.&lt;br /&gt;
&lt;br /&gt;
==Dairy Milker== &lt;br /&gt;
For animal husbandry, hay baling stores hay for the winter. Unless you are talking about the fish in your home aquaponic system. Dairy products themselves are $116B &amp;lt;ref&amp;gt;https://www.ibisworld.com/industry-trends/market-research-reports/manufacturing/food/dairy-product-production.html &amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
of the global economy - hence the relevance of the dairy milker. &lt;br /&gt;
&lt;br /&gt;
Table: values of the overall food, dairy, cattle, vegetable markets worldwide.&lt;br /&gt;
Combining the dairy milker with computer vision and automation, we envision a solar robotic milker - our MicroTrac with a milking stall - that drives up to a cow to milk her, and then brings the milk back for storage and processing. This allows field milking without human labor for small diversified robofarms that combine the best of regenerative agriculture with modern tehnology to relocalize farming.&lt;br /&gt;
&lt;br /&gt;
Fig. Robotic milker&lt;br /&gt;
==MicroTrac== &lt;br /&gt;
&lt;br /&gt;
A very interesting use arises with a small, solar, robot tractor - the MicroTrac driven by a solar panel. By adding a $10 Raspberry Pi Zero Controller &amp;lt;ref&amp;gt;https://www.adafruit.com/product/3400?gclid=EAIaIQobChMI2rz0mcnd2gIVCzlpCh3MpQgIEAQYAiABEgKi7_D_BwE&amp;lt;/ref&amp;gt; and a $100 solar panel you can be your robotic tractor - for agriculture and other. You can now mow your lawn automatically, and even pelletize it for fuel for a pellet stove. This is possible because today - advanced microelectronics such as the Raspberry Pi is 100 times faster that the first supercomputer, which cost $9M &amp;lt;ref&amp;gt;https://www.theregister.co.uk/2008/01/05/tob_cray1/ &amp;lt;/ref&amp;gt; in 1975.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
==Bulldozer==&lt;br /&gt;
&lt;br /&gt;
Now add a bulldozer blade to a beefed up, tracked tractor - and you have one of the most powerful devices for regeneration - or destruction - depending on how you use the machine. Bulldozers are powerful earth moving machines - to build roads, grade house foundations, and in agriculture - to build regenerative earthworks for water and erosion. The biggest example is the 12,000 square miles that have been regreened in China - the Loess Plateau. &amp;lt;ref&amp;gt;John Liu reported on this - http://www.aquinta.org/news/2016/10/6/greening-the-desert  &amp;lt;/ref&amp;gt;. &lt;br /&gt;

&lt;br /&gt;
So, if you ever drove on a road - you used a bulldozer. Maybe not you, but whoever graded the road base. &lt;br /&gt;
&lt;br /&gt;
==Microcombine==&lt;br /&gt;
&lt;br /&gt;
The Microombine is used to harvest grains and seeds of any type. This is the core of human harvests world wide. For the OSE case, we have a much more flexible and modular machine in mind. Based on our module-based aproach, we can use the same drive platform as the tractor&lt;br /&gt;
&lt;br /&gt;

==Bakery Oven==&lt;br /&gt;
&lt;br /&gt;
Humble bread is a $419B global market https://www.ibisworld.com/industry-trends/global-industry-reports/manufacturing/bakery-goods-manufacturing.html . It is the 12th most popular food in the world. https://www.farmflavor.com/at-home/what-is-the-most-popular-food-in-the-world/  And 49% of Americans eat bread  https://www.smithsonianmag.com/smart-news/each-day-50-percent-america-eats-sandwich-180952972/ . &lt;br /&gt;
&lt;br /&gt;
Now bulldozers, tractors, and combines are all good - but the next step for gobal agriculture is the transition to  perennial polyculture  https://www.youtube.com/watch?v=KpJR2yfLUU0  , with only a small fraction of tillage ramaining.&lt;br /&gt;
&lt;br /&gt;
=Construction - 13 Tools=&lt;br /&gt;
If you want to build a charter city or a smaller campus, you will need construction equipment - and a trencher to put in gigabit internet fiber between the locations.&lt;br /&gt;
&lt;br /&gt;
The tools in the construction part outside of the tractors include the backhoe, trencher, cement mixer, sawmill, CEB press, well-drilling rig, soil pulverizer, hammermill. The universal rotor is a tool used in other sectors of the GVCS - and the SeedHouse is a living machine. &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Fig. 13 tools of the construction part of the Global Village Construction Set.&lt;br /&gt;
&lt;br /&gt;
==Backhoe, Trencher, Cement Mixer==&lt;br /&gt;
&lt;br /&gt;
The backhoe or excavator can be used to dig aquaponic ponds, foundation trenches. It can be used to remove stumps, do trenching, and with a grapple it can be used to lift logs or to hoist heavy objects. Backhoes are relatively simple devices - a set of pivot joints that use hydraulic cylinders for their motion - producing thousands of pounds of digging force at the touch of control levers. There are both side-to-side moving backhoes, but a 360 degree rotating backhoe is much more flexible. The small side to side version can be used on a front quick attach of a tractor.&lt;br /&gt;
&lt;br /&gt;
Fig. OSE backhoe from 2010 https://www.google.com/search?q=ose+backhoe&amp;amp;client=ubuntu&amp;amp;hs=ToH&amp;amp;source=lnms&amp;amp;tbm=isch&amp;amp;sa=X&amp;amp;ved=0ahUKEwjLzZKelOLYAhULbawKHQo-DVwQ_AUICigB&amp;amp;biw=1351&amp;amp;bih=731#imgrc=t8j52U9--mn6BM:  mounted on he original lifetrac, a small one used for water line trenching in 2012 http://opensourceecology.org/wiki/File:Bhp1.jpg , and a larger one from 2013 https://www.youtube.com/playlist?list=PL6Jpysxw3Ty-oH4bggp32PR_rPWr8bKC1 . Next iteration is the 360 degree backhoe with remote control drive to facilitate hydraulic line routing.&lt;br /&gt;
&lt;br /&gt;
The trencher in the original GVCS icon is a wheel trencher. We built 2 prototypes, and the next iteration will be a chain-based trencher based on our favorable experience with oversized chain drive on the bulldozer tracks.&lt;br /&gt;
&lt;br /&gt;
Fig. OSE Trencher http://opensourceecology.org/wiki/Trencher - 2011 and 2013 builds.&lt;br /&gt;
The cement mixer is indispensable. Cement has been used in ancient Rome and in mesoamerican temples. Scotland&#039;s County Cork had 23,000 lime kilns at one time - had one kiln per 80 acres. Wood or coal was used as fuel. http://www.lowtechmagazine.com/2013/09/lime-kilns.html  http://www.chapelgatehome.uk/our-blog   Portland cement took over lime cement in the last 100 years, but lime concrete is favorable in foundations becaue it doesn’t crack as easily as Portland. Using modern appropriate technology, lime cement production in solar microfactories is a viable enterprise at the 1 ton per day scale using an open source microkiln the size of a refrigerator. Limestone goes in one end, and lime comes out the other. With such small appliances costing around $1k, cement production can be distributed - while making cement production carbon neutral, annihilating  the current 5% CO2 emission share of the the concrete industry.https://en.wikipedia.org/wiki/Environmental_impact_of_concrete  This is possible in about 50% of America, where the bedrock is made of limestone. That’s a $10B industry in the USA alone.https://en.wikipedia.org/wiki/Cement_industry_in_the_United_States &lt;br /&gt;
&lt;br /&gt;
The cement fryer - a rotary lime kiln - is much like the cement mixer: a Universal Rotor with a heating element. A rotating pipe heated by PV, and an Arduino microcontroller to measure temperatures and guide the process to efficient completion. While not part of the 50 GVCS technologies, it’s a ready derivative:&lt;br /&gt;
&lt;br /&gt;
Fig. PV of the Open Source Materials Production Facility, a solar Power Cube, a Universal Rotor, metal pipe and an Arduino microcontroller constitute the lime cement maker.&lt;br /&gt;
&lt;br /&gt;
If we want to go to the essence of construction, take the backhoe excavator, chase it with a bulldozer with ripper shanks, and then rock under a site could be extracted to build a pond. This rock, if limestone, is feedstock for your lime kiln. In some places, rock outcroppings make access to limestone easy.&lt;br /&gt;
&lt;br /&gt;
==CEB Press , Soil Pulverizer, and Sawmill==&lt;br /&gt;
&lt;br /&gt;
The Compressed Earth Brick press and sawmill are critical tools for construction in that they produce materials. The CEB Press allows one operator to load raw dirt right from the building site to produce about 5000 bricks in a day - enough for a small house. &lt;br /&gt;
&lt;br /&gt;
Fig. The CEB Press is the first machine that we have prototyped, and it is ready for widespread replication around the world.&lt;br /&gt;
&lt;br /&gt;
We have used the soil pulverizer to prepare soil for pressing CEB blocks. The soil pulverizer was used to both pulverize the soil, and its bucket was used to press bricks for CEB construction.&lt;br /&gt;
&lt;br /&gt;
Fig. Soil pulverizer - Aidan on the tractor + loading the brick press by Yoonseo&lt;br /&gt;
&lt;br /&gt;
Our next step on the CEB press is a full soil conditioner which pulverizes soil, adds cement at a measured quantity of 5%, and then loads the mixture into the CEB press - to allow for production of high quality, stabilized block.&lt;br /&gt;
&lt;br /&gt;
Fig. The soil conditioner accepts raw soil from a tractor loader, mixes a measured amount of cement, and loads the prepared mixture into the CEB press for effective production of stabilized block at 12 cents ( 10 cent cement cost for a 20 lb block, and 2 cents gasoline cost). per block in materials. This means that we can build a 1’ thick CEB wall section for $50 in materials.&lt;br /&gt;
&lt;br /&gt;
The sawmill is a machine that can produce dimensional lumber - a staple of construction. Our sawmill is a variety known as a swing-blade sawmill, which has a single blade that can rotate 90 degrees and make a dimensional piece of lumber by going forward and back on a piece of wood.  We chose the dimensional sawmill for its simplicity over a bandsaw mill, as blade sharpening is much easier - and maintenance is the larger cost of any equipment if that equipment is designed for a lifetime.&lt;br /&gt;
&lt;br /&gt;
The sawmill is a good example of how we can use GVCS product ecologies to reduce complexity and reduce the cost of equipment. We design not just individual machines, but machine ecosystems that feed off one another. We can obtain drastic cost reduction by borrowing existing modules from the GVCS. For our case, it makes sense to design the sawmill as a Bobcat standard quick attach implement. We borrow the tractor as a  quick attach point, so that we do not need a bed upon which the sawmill head would otherwise ride. We borrow 32 hp from the tractor Power Cubes. We also  borrow the hydraulic motor which we attach with hydraulic quick-connect hoses. Thus, we have essentially stripped down the entire sawmill to the long carriage with the cutting head - saving $2k https://www.ebay.com/itm/30hp-Kohler-Engine-1-1-8-D-Command-15Amp-Exmark-CH750-0026/132423001888?epid=26011371639&amp;amp;hash=item1ed506a720:g:4YUAAOSwH2VaS3-h  on the engine, $2k https://sleequipment.com/dovetail-utility-trailer-7x20-with-3500lb-axles.html?fee=8&amp;amp;fep=524834&amp;amp;gclid=EAIaIQobChMIws349azn2AIVBqxpCh1rMwbpEAQYASABEgIeHPD_BwE  on a trailer. The greatest advantage would be the setup time - if designed as a quick attach implement, the sawmill can be taken to a log, rested right by the log, and ready for action - as compared to systems where the carriage base must be set up or the log moved into cutting position. If the sawmill can straddle right over a log or be raised with the loader arms, there is no limit ot the size of log that the mill can handle. &lt;br /&gt;
&lt;br /&gt;
Fig. The simplicity of the OSE swing-blade sawmill involves a long linear track mounted as an implement for the tractor. To provide 3 axes of motion - the loader mounting includes height adjustment (z motion), and a lightweight cantilevered head provides side-to-side motion. The cost of about $1500 is significantly lower than the $15k http://www.dltimbertech.com/dl-180-swing-blade-sawmill-10-x-20.html   minimum for a comparable 32 hp sawmill. (ref)&lt;br /&gt;
&lt;br /&gt;
And the sawdust that we generate can be used as animal bedding, insulation, or it can be pelletized to make fuel pellets.&lt;br /&gt;
&lt;br /&gt;
==Universal Rotor==&lt;br /&gt;
&lt;br /&gt;
The Universal Rotor is a fundamental building block for just about any moving machine. It is a combination of rotary motion and a useful tool-head. As a design pattern consisting of a shaft, bearings, and a motor -  a wide array of working tools can be attached to it - so that the Universal Rotor can constitute a drill, a wind turbine,  a wheel, a hammermill, cement mixer, sawmill - etc  - essentially any machine at any size - from small cordless electric drills to a larger 50kW rotor of a wind turbine. &lt;br /&gt;
The Pelletizer , Chipper/Hammermill, Dimensional Sawmill, Rototiler/Soil Pulverizer, Cement Mixer, Well-Drilling Rig, 50 kW Wind Turbine, Microcombine Thresher, and Bioplastic Extruder are direct applications of the universal rotor, and combined with precision machining structures, the Universal Rotor also include the heavy duty CNC Multimhttps://www.opensourceecology.org/portfolio/pelletizer/achine with lathe, drill press, slow cutoff saw, surface grinder, and other machines of fabrication.&lt;br /&gt;
If we can build a Universal Rotor, a Power Cube, and weld together  a supporting structure - then we have - broadly speaking - build 23 of the 50 machines of the GVCS. For example, if we consider the electric motor - it is a a shaft, 2 bearings, a structure, and the ‘tool head’ could be considered the electrical windings that make the shaft spin. Or, if we consider the metal lathe - a part of the Multimachine - then it is clear that the lathe consistr faksdjdfjks of a heavy shaft, 2 heavy bearings, and the tool-head is a chuck for holding work-pieces.&lt;br /&gt;
&lt;br /&gt;
==12. Well-Drilling Rig and Chipper/Hammermill==&lt;br /&gt;
The well-drilling rig is a machine used to dig deep water wells. It consists of a universal rotor which uses 3” (https://www.aquascience.net/grundfos-10sq05-160-230v-10gpm-1-2hp-230v-2-wire-96160140-3-stainless-steel-submersible-well-pump?gclid=EAIaIQobChMIlt-S3PDn2AIVC6tpCh369g34EAQYASABEgJr__D_BwE. 10’ of this pipe store 4 or 6.5 gallons of water. ) or 4” drill pipe to drill down to a depth of 100m or more using hydraulic rotary drilling. In this method, a stream of water is sent down the pipe during the drilling operation to send up tailings and soften the area of the drill point. A heavy duty hydraulic motor spins the drill rod - and new sections of drill rod are attached one after another. When the operation is done, the drill pipe is left underground and a submersible pump is inserted to pump water from the well.&lt;br /&gt;
Fig. A hydraulic deep well pump drilling system explained. The water swivel is the key part here. Otherwise 3” pipe that an be used as  drill pipe and casign is $12/foot. https://www.discountsteel.com/items/Galvanized_Steel_Pipe.cfm?item_id=172&amp;amp;size_no=11#skus  &lt;br /&gt;
The chipper/hammermill is another application of a universal heavy rotor with swinging or fixed blades. This machine shreds or pulverizes materials, and can be as small or large as needed.&lt;br /&gt;
Fig. Hammermill variations with various blades to chip wood or crush rock. A modified version of a heavy rotor can be a grinder. The scale can be from the largest - shredding cars - to the smallest - with small electric motors - if you have hydraulic drive and electric drive.&lt;br /&gt;
&lt;br /&gt;
==The House - Seed Eco-Home and Aquaponic Greenhouse==&lt;br /&gt;
&lt;br /&gt;
The Seed Eco-Home is a living machine - and becase it is the single largest cost of living today, we dediced to include that in the GVCS. (Initially, the house was not in the GVCS - but it was added as the Microhouse.) The  The Seed Eco-Home is the culmination of all the construction machines put to use. Homes are  also about  $3T (https://en.wikipedia.org/wiki/Construction#Industry_characteristics - residential construction is about ⅓ of all construction) market worldwide - which if open-sourced, could provide 30 million regenerative housing jobs for open source home building entrepreneurs Earning $100k each per year. This is 30 million potential collaborators - through we need only about 1000 at this time.&lt;br /&gt;
&lt;br /&gt;
The OSE/OBI https://www.openbuildinginstitute.org/  Seed Eco-Home is a an affordable, expandable eco-home that can be built for ⅓ the cost of a typical home, while including ecological features. Rather than building a large house, we propose starting with a seed home, and then growing it as the need arises. &lt;br /&gt;
&lt;br /&gt;
We are pushing ecological limits in our autonomous house design. The house is  off-grid with PV, provides its own cooking fuel from a biodigester, includes roof-top rainwater collection, and grows its own food with an aquaponic greenhouse. Mowed lawn or biomass is used to provide heating biomass pellets for a hydronic stove that is fueled by pellets. The eventual product vision is a house that  produces fuel for cars as compressed biogas or compressed hydrogen - by splitting water. Thus, we are correcting the oil and gas industry with 100% renewable energy, using simple, proven technologies. We are not relying on advancements in battery technology as a prerequisite to sustainable transportation, and by not requiring scarce lithium for batteries, we are aiming for an abundant and environmentally friendly energy future. http://www.kitco.com/ind/Albrecht/2014-12-16-How-Green-is-Lithium.html  We favor rooftop PV plus electrolysis as the preferred route for transportation fuels, where every house becomes a gas station. Using medium pressure electrolyzers that can produce hydrogen up to 33 atmospheres without needing a compressor - we can readily store hydrogen in large propane tanks or higher pressure steel pipe. &lt;br /&gt;
&lt;br /&gt;
Fig. Seed Eco-Home&lt;br /&gt;
&lt;br /&gt;
Fig. Aquaponic greenhouse glamour shot.&lt;br /&gt;
&lt;br /&gt;
The aquaponic greenhouse is designed to provide a year-round supply of fresh eggs, vegetables, fish, and mushrooms. The goal is to include automated planting with a small Farmbot (https://farm.bot/ . By Shuttleworth Fellow friend Rory Aaronson.), where the resulting deep pots are planted in the  towers. With a 1000 plant growing capacity in the main towers, the greenhouse can provide a robust salad daily, where we plant and harvest 15 plants per day from a small 800 sf greenhouse. A mushroom yield of 1lb is obtained per week from a tower that takes only 1 square foot. We also intend to use automated 3D printed aerial drones for planting seeds directly into towers - a great example of useful product ecology. Local food addresses the issue of food miles, where food travels an average of 1500 miles in the USA before ending up on someone’s plate. https://cuesa.org/learn/how-far-does-your-food-travel-get-your-plate  This is one of the numerous inefficiencies that will be addressed by a more efficient, open source economy. This brings us to transportation.&lt;br /&gt;
&lt;br /&gt;
=Transportation. =&lt;br /&gt;
&lt;br /&gt;
The microcar, truck, electric motor, and hydraulic motor are the 4 GVCS machines directly related to transportation. &lt;br /&gt;
&lt;br /&gt;
The worldwide production of cars is a total of 95M per year, 75% of which is done by the top 15 companies. https://en.wikipedia.org/wiki/Automotive_industry#World_motor_vehicle_production  This lends itself to massive distribution of power. The OSE paradigm proposes instead that there would be on the order of million distributed enterprises - essentially one per 10,000 people. Each facility would produce cars on the scale of dozens or hundreds in the community-supported manufacturing (CSM) scenario. Thus, car producers replace car dealership  - as the producer takes to dealing.  This would go well with a gas station at every home, splitting Seed Eo-Home rooftop water for fuel at a cost of 80 cent per gallon of gasoline equivalent. http://opensourceecology.org/wiki/Hydrogen_Production &lt;br /&gt;
&lt;br /&gt;
Fig. Seed Eco-Home to car fuel infrastructure consists of rooftop water collection, 10kW of PV panels, a storage tank for hydrogen, and compression to 200 bar. Piece of cake if you consider not doing this - wars for oil. This gives us about 100 miles of fuel worth per day in a 100mpg microcar.&lt;br /&gt;
&lt;br /&gt;
==OSE Microcar==&lt;br /&gt;
&lt;br /&gt;
The OSE Microar is a Hydrogen Hybrid Hydraulic (H3) vehicle. Hydrogen is chosen because an internal combustion (ICE) engine running on hydrogen is twice as efficient (40%) as a normal ICE (20%), and only 25% under the 50% efficiency of fuel cells. http://environment.yale.edu/gillingham/hydrogenICE.pdf A hydraulic drive train (71% efficiency) - has a higher efficiency than a continuously variable transmission (60%) for fuel cell electric vehicles - meaning that the humble hydrogen hydraulic car gets a higher mileage than a fuel cell car, at significantly lower cost. At a design weight of only 850 lb, less than ¼ of a typical car, the OSE microcar focuses on moving the passenger, not a large chunk of metal accessory to the core purpose. Lighter cars have a good safety record. Before the S.U.V. boom, the country (USA) had the world&#039;s lowest highway death rate.http://www.nytimes.com/2004/05/05/business/averag e-us-car-is-tipping-scales-at-4000-pounds.html  Additionally, gas mileage for the OSE Microcar is specified for 100mpg. While not as testicular as a Tesla, the OSE specification requires higher self-esteem on the part of the driver to accept acceleration from 0-60 of 12 seconds, as opposed to under 3 seconds for a Tesla Model S.https://en.wikipedia.org/wiki/List_of_fastest_production_cars_by_acceleration&lt;br /&gt;
&lt;br /&gt;
Fig. The OSE Microcar concept.&lt;br /&gt;
&lt;br /&gt;
Can smaller cars are safer? This is controversial. https://www.ptua.org.au/myths/smallcar/  Physics says that energy of motion is proportional to v squared, and data shows that 56% of car deaths are single-car collisions. So unless you are going to hit another oncoming car or an immovable object like a large tree, your tiny car of under 1000 lb  has 36x less energy to dissipate than a Chevy Suburban of 6000 lb. And, the lightest car - the Smart Carfortwo at 1800 lb http://driving.ca/hyundai/accent/auto-news/news/these-are-the-ten-lightest-cars-you-can-buy-in-2015  and it certainly does get eaten up in a frontal 2 car collision with a larger car. And crashes took more than 37k lives in the US http://www.iihs.org/iihs/topics/t/general-statistics/fatalityfacts/state-by-state-overview#Crash-types  , with 20-50x more if injuries are counted. http://asirt.org/initiatives/informing-road-users/road-safety-facts/road-crash-statistics (are injuries better or worse in large cars?)&lt;br /&gt;
&lt;br /&gt;
But this is all before self-driving cars enter the scene - which have been tested for 0 driverless car crashes over 1.8 million miles by Google - with 13 fender benders caused by other cars. http://bigthink.com/ideafeed/googles-self-driving-car-is-ridiculously-safe  In other words, the case is there for super-small, super-efficient cars that are robotically controlled. &lt;br /&gt;
&lt;br /&gt;
What we have in mind follows the standard of the 200 mpg fuel efficiency of the VW  L1 first prototype car, at 640 lb weight, 8 hp, top speed of 75 mph, with tandem seating for 2. https://en.wikipedia.org/wiki/Volkswagen_1-litre_car. The efficiency dropped to 170 mph in a hybrid version - http://gas2.org/2009/09/14/volkswagens-diesel-hybrid-1l-concept-gets-170-mpg-available-by-2013/  If OSE achieves the same with 16 hp instead of 8 hp, and using hydraulics while not needing to go to a hybrid drive-train that apparently reduced its initial mileage performance - then we will have a major victory for open source-  Hydraulic accumulators may be used for peak power.  Plus, we’d like to achieve this with hydrogen as fuel in later versions.&lt;br /&gt;
&lt;br /&gt;
More specifically - our model is an H3E car - including a hybrid electric component.  The hydraulic component is a peak power electric-hydraulic micro-Power Cube of about 40 lb additional weight - powered by the onboard starter battery for its cranking amps.  This additional 30 seconds of a starter battery would double the power of the 16 hp engine - such that burst of energy for passing and sudden acceleration can be achieved easily.&lt;br /&gt;
&lt;br /&gt;
==B The Solar Car==&lt;br /&gt;
&lt;br /&gt;
The Solar Challenge is a fascinating event that shows PV-covered cars traveling 62 mph average across Australia. Granted that the driving is in expensive prototypes ad a sunny country - only in daytime - this still bodes well for the feasibility of solar transportation. The typical cars used are small - surface area of a Toyota Prius - and the OSE version would be twice as large 24x8 feet for 3kW of installed PV + 44 lb Lithium ion batteries + 2.5 kW small engine. http://opensourceecology.org/wiki/Solar_Car This allows for a total of 7kW of continuous power for one hour, or 4 kW total power continuous - at 750 lbs of weight. This just may work - if we 3D print a form frame for carbon fiber layup. 3D printing here may be the enabling technology.&lt;br /&gt;
&lt;br /&gt;
==Truck==&lt;br /&gt;
&lt;br /&gt;
The truck is a medium-size, hydraulic, 80 hp driven vehicle comparable to the Mercedes Unimog. https://en.wikipedia.org/wiki/Unimog  With a design top speed of 62 mph,  a weight of 6550 lb, and a hydraulic power take-off, the OSEmog could function as an agricultural tractor as well. The OSEmog is designed to accept a loader or various implements on the front or back. Using basic hydraulic circuits, the machine would have high and low gear, and speed cotrol via simple flow control valves.&lt;br /&gt;
&lt;br /&gt;
Fig. The OSEmog is a multipurpose truck for carryng loads or operating various implements. With off-the shelf parts, it is designed to be field serviceable, and the working hydraulic fluid can be grown - canola oil with additives.&lt;br /&gt;
&lt;br /&gt;
==Hydraulic and Electric Motors==&lt;br /&gt;
&lt;br /&gt;
Both the car have a choice of using hydraulic or electric drive. The advantages of hydraulics are low-cost, high torque, and simplicity of resulting drive design. Hydraulic motors cost only $10/hp, half that of electric motors - but a typical 40 hp hydraulic motor weighs about 50 lb http://opensourceecology.org/wiki/45.6_Cu_In_Hydraulic_Motor as opposed to about 350 lb https://inverterdrive.com/group/Motors-AC/TECA2-200L-4-Pole-B3-High-Efficiency-AC-Motor-200/ .  Typically electric motors are high speed and need to be geared down - whereas hydraulics can be used largely with direct drive. If high torque electric motors are used - these are more like $100/hp when the controller is included - making the drive system 10x as expensive for larger machines.  Electric motors are sensitive to moisture and dirt, while hydraulics are designed for dirty environments. &lt;br /&gt;
&lt;br /&gt;
We electric motors and generators - in solar electric power cubes - or in wind turbines. But the flexibility, power, and simplicity of hydraulics is a better choice for practical applications - especially when powered by hydrogen and transmitted by canola oil as the hydraulic fluid.&lt;br /&gt;
&lt;br /&gt;
The electric motor can also be 3D printed, making it fit with the OSE product ecology. &lt;br /&gt;
&lt;br /&gt;
Fig. A proprietary, 3D printed, 600W, 80% efficient electric motor. The equivalent is worthwhile to open-source.&lt;br /&gt;
&lt;br /&gt;
Electric motors can be both linear and rotary. In the linear form, they are known as solenoids - very useful devices that are used to make valves. For automation - we use dydraulic valves to control machines like the brick press - and solenoids are used wherever pneumatic or hydraulic controls are needed. This means any automated system - from the water control in aquaponics to the control of an industrial robot.&lt;br /&gt;
&lt;br /&gt;
The electric motor of interest ranges from a small 5W one to power a cordless drill - to the 50kW scale for use in the 50kW wind turbine.&lt;br /&gt;
&lt;br /&gt;
This brings us to the energy sector.&lt;br /&gt;
&lt;br /&gt;
=Energy Tools=&lt;br /&gt;
&lt;br /&gt;
The sun currently shines 10000 times more power to the earth than the entire civilization uses. The implications are profound: there is no such thing as an energy shortage. Energy scarcity is an imagined problem if we talk about actual availability of energy.&lt;br /&gt;
&lt;br /&gt;
We look at it as- it is a high priority to trap solar energy directly - by effective solar design of buildings (Homes and businesses spend about 50% of their energy on heating and cooling. )- and using photovoltaic energy (Solar Concentrator) to generate electricity locally, with wind (50kW Wind Turbine) wherever possible. For machines, the choice is to use hydrogen, charcoal, and compressed biogas. &lt;br /&gt;
&lt;br /&gt;
Hydrogen is by far the most efficient and clean when derived from water (as opposed to refining from oil and gas).  The process gives 0 pollution, and the product of hydrogen combustion is water. The OSE platform calls for provent internal combustion engines running on hydrogen as an immediately executable transition to a renewable energy future in transportation. Leading research institutes, such as the Rocky Mountain Institute (ref), promotes the hydrogen economy as the future, and hydrogen as a future energy source is not controversial if one assumes abundance of fuel feedstocks and distribution of energy production. Solar hydrogen can be produced anywhere, and wind hydrogen can be produced in most places around the world. We do not put such a high stake into batteries or supercapacitors when it comes to energy for cars, simply because chemical fuels are up to 140 times as energy dense. A typical energy density chart typically has chemical fuels off-the-charts good:&lt;br /&gt;
&lt;br /&gt;
Fig. Show specific energy density of storage media, with bats and caps, and chemical fuels, for perspective - https://en.wikipedia.org/wiki/Supercapacitor#/media/File:Supercapacitors-vs-batteries-chart.png. With supercapacitors having 100x less energy storage per weight than Lithium-Ion batteries, while costing 10x as much as ($2.85/kJ) as those batteries ($0.8/kJ), they are super-completely out of the question with today’s technology except for niche applications. Engines are .5kW/kg https://en.wikipedia.org/wiki/Power-to-weight_ratio#Engines  and Fuel (gas, diesel, methane) is 50MJ/kg and hydrogen is 140MJ/kg - or 50-140x more energy per weight than batteries. Given the environmental challenges of mining and recycling scarce metals, there is little case for battery-powered cars.&lt;br /&gt;
&lt;br /&gt;
That means that a non-battery car can lug around a higher percentage of payload (persons, cargo) rather than carrying around more car structure and batteries. &lt;br /&gt;
&lt;br /&gt;
For other purposes, biofuel pellets are desirable for heating fuel (after energy efficiency and solar thermal is maxed out) - such as by an aquaponic greenhouse with a black tubing heat exchanger.&lt;br /&gt;
&lt;br /&gt;
Biofuel pellets can be burned partly to release heat in winter - and if taken out of combustion after the volatile chemicals are burned off but before carbon burns to ash - then we have produced charcoal that can be used in a combustion engine. Thus, dual-fuel hydrogen/charcoal cars are in our view the transportation of the future. We are open to fuel cells entering the scene, and at $134/kW they are almost feasible.https://energy.gov/eere/fuelcells/fuel-cell-technologies-office-accomplishments-and-progress  They are too complex at this point for easy DIY production, so we may revisit this in 10 years if the technology becomes more accessible. Currently, fuel cells require exotic plastics and platinum, both of which are scarce resources. We are aiming for a sub $10k car which can be made with a standard internal combustion engine (ICE) running on hydrogen. Did you know that the first internal combustion automobile in the world ran on hydrogen in 1808? https://en.wikipedia.org/wiki/Fran%C3%A7ois_Isaac_de_Rivaz  Furthermore, ICEs are about 20% efficient - ICEs running on hydrogen are about 40% efficient. For comparison,  fuel cell vehicles are 50% efficient.http://environment.yale.edu/gillingham/hydrogenICE.pdf  Given that the efficiency gain of 25% of fuel cells over hydrogen ICEs comes at a 10x larger cost today, the case for pursuing hydrogen ICEs is much higher than the case for fuel cells. much cheaper H2ICE are seen by many experts as the means to provide a transition between emitting and non emitting transport and stationary system. https://pureenergycentre.com/hydrogen-engine/ &lt;br /&gt;
&lt;br /&gt;
Fig. The possible cost of a fuel cell car today for a 200kW sedan is $26k - and an overall minimum of about $75k. The open source hydrogen microcar is aimed at an under $10k cost and more than 100 mpg using widely available technology. (comparison of components and price, using ref 3 above)&lt;br /&gt;
&lt;br /&gt;
The answer already under our nose that is perhaps the most optimistic case for the energy revolution is solar power - at 0.015 cent per kilowatt-hour - demonstrated in 2016 by the Seed Eco-Home. http://opensourceecology.org/wiki/Hydrogen_Production  This is 4x cheaper than gas turbine electric generation  https://qz.com/135032/fuelcell-energy-fuel-cell-profit/  , and it allows for an equivalent 80 cent per gallon electricity cost for producing hydrogen.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
==The Power Cube==&lt;br /&gt;
&lt;br /&gt;
Our current Power Cube is a universal power unit that can power any of the large GVCS  machines, from cars to lathes to the brick press. The Power Cube is gasoline powered and has a 16 hp engine. We already ran this on charcoal gas - and as such - the same power cube can readily be used in dual-fuel operation - gasoline on the one hand, and charcoal on the other. Once we add the gas production infrastructure - the power cube can run on the hydrogen and biogas production from the House.  Because the pelletizer is part of the GVCS - we can make charcoal pellets from biomass pellets as a byproduct of space heating.  The concept of pellets is important - in that pellets are a flowable fuel. Meaning - that just like gasoline or tradition fuels - it can be stored in a tank and delivered as fuel as if it were a liquid - by using a small auger. This makes pellets a convenient fuel source, which unlike wood - can be used automatically in small machines.&lt;br /&gt;
&lt;br /&gt;
Moreover, the Power Cube can be run on solar energy, allowing for autonomous tractors and solar cars to enter. Solar power cubes are a good idea for shop power - where PV on the workshop roof feeds electric power cubes for hydraulic shop power. Power cubes can also be made very small - on the 1 kilowatt scale. They can also be stacked readily for higher power, so if we want a 160 hp bulldozer, we can do that based on our existing Power Cube.&lt;br /&gt;
&lt;br /&gt;
The Power Cube involves developing open source engines so that they enter the realm of lifetime design public technology. A universal version of an open source engine means that such an engine could be maintained and produced in a distributed fashion, bringing it closer to appropriate technology with a lifecycle that includes more reusability of parts.&lt;br /&gt;
&lt;br /&gt;
Fig. The Power cube and its different fuel sources - from gasoline, to charcoal, to compressed biogas, hydrogen, and electric.&lt;br /&gt;
&lt;br /&gt;
The large torque of hydraulics makes them very flexible for driving a wide range of machines. A small power cube, such as a 300W version running on a single solar panel, can be used to drive a 2000 lb MicroTrac as a practical, autonomous tractor.  The idea is that the machine would move very slowly - all day - on solar power. This is afforded by that fact that hydraulics have high torque at any speed - making this a perfect application of solar energy to autonomous, robotic tractor drive via a small microcontroller such as a $10 Pi Zero with Wireless.https://www.adafruit.com/product/3400   Thus, we can pull chicken tractors or pig tractors with a solar robotic tractor for a diversified agriculture operation.&lt;br /&gt;
&lt;br /&gt;
Fig. Infographic. Mega power cubes for 160 hp for a bulldozer, and a micro power cube for a solar grinder/pelletizer or chicken tractor.&lt;br /&gt;
&lt;br /&gt;
Autonomous animal tractors are another possible application of Power Cubes…&lt;br /&gt;
&lt;br /&gt;
Fig. The economic breakdown of an autonomous chicken tractor. PV panel + micro power cube at $500, plus the tracked drive for another $500 with open source hydraulic motors. The hydraulic motors (SME) are produced on the open source lathe (SME).&lt;br /&gt;
&lt;br /&gt;
==The Gasifier ==&lt;br /&gt;
&lt;br /&gt;
The OSE  gasifier is a device that converts charcoal into gas for fueling engines. Note that this gasifier uses charcoal that is produced as a byproduct of space heating. The gasifier is a metal container filled with charcoal, which upon being lit via in a small burn zone with an air inlet - burns and produces gas. This gas can be used as fuel in a regular internal combustion engine. The power of this lies in that with minimal modifications, a standard engine can be fueled by charcoal - which is derived from wood or other biomass.  This means that wherever plants grow - they provide a distributed and practical fuel source byond oil wars. https://www.cnn.com/2013/03/19/opinion/iraq-war-oil-juhasz/index.html  To produce charcoal, biomass is first pelletized. Burning pellets for space heat - and removing them from the burn before they turn to ash - produces charcoal pellets.&lt;br /&gt;
&lt;br /&gt;
Fig. Infographic. Space heating produces charcoal in the OSE ecosystem.  The Gasifier vaporizes charcoal, which is then burned in a standard engine. This process can be used to fuel cars - no engine modification required.&lt;br /&gt;
&lt;br /&gt;
The first reaction may be that if we turned plants into vehicle fuel - then we would destroy all of nature. That is not true, because there is plenty of biomass reserve that can be used to fuel the entire American car fleet, which uses about 60% http://needtoknow.nas.edu/energy/energy-use/transportation/  of all the energy in the transportation sector. Did you know that the largest single crop in the United States is lawn? There are 40 million acres of turf grass. http://scienceline.org/2011/07/lawns-vs-crops-in-the-continental-u-s/  What if we turned lawns into fuel crop, while increasing esthetics and reducing herbicides? Yields of grass are 4 dry tons per acre https://en.wikipedia.org/wiki/Biomass  - and if charcoal is produced at 25% efficiency - that is one ton of charcoal per acre - or 40 million tons of charcoal can be harvested from lawns alone, with no effect on food production, while increasing the ecological diversity of lawns. The average american uses 500 gallons per year of fuel.  https://www.treehugger.com/culture/pop-quiz-how-much-more-gas-do-americans-use.html  Lawns could thus provide ¼ of the entire car fleet fuel in the USA! (Charcoal is ¾ the energy content of gasoline by weight. At about 3 kg/gallon - 500 gallons is 1500 kg- about 1.5 metric tons - so 33M people could be supplied by fuel from lawns. If 95% of households have cars - https://photos.state.gov/libraries/cambodia/30486/Publications/everyone_in_america_own_a_car.pdf - and household is 2.6 - there are about 120M drivers in the USA. Thus  - ¼ of US drivers can be fueled by lawns.) This is at the crappy USA 23 miles per gallon - so increasing fuel efficiency to 100 mpg https://www.motherearthnews.com/green-transportation/green-vehicles/build-your-own-car-zm0z13amzmar with super-efficient micro-cars could mean that the entire US car fleet is supplied by fuel from grass. Efficiency and ecology - as opposed to battery technology with questionable environmental side effects and its centralization based on scarce resources - make the OSE platform converge on biomass and hydrogen as the fuels of choice. The OSE platform reserves the role of batteries only as a small part of vehicular power, not the backbone of the auto industry. &lt;br /&gt;
&lt;br /&gt;
The biomass route needs no technical invention to realize - today - and is also a carbon-neutral route. From the OSE perspective - hydrogen is clean (it produces water as the byproduct) but not better on ecological grounds (it does not contribute to biological ecology) - but it is much better on efficiency grounds.&lt;br /&gt;
&lt;br /&gt;
When discussing biofuels, it is important to point to the food-fuel-fiber integrated agroecology route as the preferred OSE route to agriculture. As opposed to genetic engineering to produce super-crops, the OSE platform favors ecological integration over genetic manipulation - so that we avoid creating super-problems at the same time. The ecological route means that we learn more about dealing with integrated ecosystems, not trying point solutions (genetic engineering) as a cure. When dealing with powerful technologies like genetic engineering, we must pay attention to unintended consequences. The current economic paradigm of profit maximization is not compatible with care in the use of genetic engineering. We favor increasing productivity by stacking yields of multiple crops that work harmoniously in a polyculture setting - with tree crops as a significant component. For us, the breakthrough work of Badgersett Research Farm is seminal in providing this leadership. They are developing perennial crops (hazelnuts and chestnuts) that could serve as a viable replacement for soybeans and corn. (ref).  Hazelnuts and chestnuts provide the same nutrition as their annual counterparts - but are perennial - and therefore do not contribute to the average 4 ton per acre annual soil erosion in the United States. (ref). Let me repeat that - the avarage topsoil loss in the United States - per acre - is 4 tons. What that means is that agricultural soils today are so depleted that they could not grow crops if it were not for the heavy inputs of fertilizers. The biological activity of commercial farmland is severely depleted (ref), not sustaining the soil food web of microbes that bring fertility back to the soil. (ref). Our proposition for perennial polyculture - is not new (ref on seminal works, Tree Crops, Regrarians, etc) - and it can produce food, fuel, and other materials.&lt;br /&gt;
&lt;br /&gt;
To improve the world, all you need to do is plant trees. Desertification still claims an additional ______________ square miles every year, and it would be good to reverse that.&lt;br /&gt;
&lt;br /&gt;
It takes less than 60x the land area to produce solar hydrogen compared to the land area required to grow biofuel crops.  Between biofuel (easy) and hydrogen (hard), humanity’s fuel needs can be met. Let’s look at numbers: we already said 300 gallons of fuel equivalent per acre (enough to fuel one car for a year at a fuel economy of 40 MPG https://www.google.com/search?q=average+miles+per+year+usa&amp;amp;oq=average+miles+per+year+usa&amp;amp;aqs=chrome..69i57j0l2.7415j0j7&amp;amp;client=ubuntu&amp;amp;sourceid=chrome&amp;amp;ie=UTF-8 ) fuel consumption -  roughly one gallon per day. If we apply this to hydrogen - 50kWhr of electricity is required to produce 1 kg of hydrogen, roughly one gallon gas equivalent. This can be obtained from a 9 kW PV array - running 6 hours per day - 54kWhr. The space required for a 9 kW array is 60 square meters if the panels are 15% efficient. An acre is 4000 square meters - so producing solar hydrogen requires 66 times less land area than growing the equivalent grass. Our materials cost for 9 kW of solar panels is under $9k. So one can obtain 20 years of hydrogen fuel for a PV investement cost of $17k.&lt;br /&gt;
&lt;br /&gt;
Fig. Home hydrogen production. The OSE open source goal is $9k for PV panels, $2k for storage, $2k for pump, $2k for plumbing, and $2k for the electrolyzer. That is $17k for a lifetime supply of hydrogen. Compare to gasoline - $1250/year on average. Payback time for  home fuel station is 14 years in the USA and 7 years in Europe. We intend to make hydrogen production a standard feature of the Seed Eco-Home.&lt;br /&gt;
&lt;br /&gt;
Add a paragraph about renewable energy plantations - perennial polycultures for fuel, food, fiber. &lt;br /&gt;
&lt;br /&gt;
Fig. Basic economic model for renewable energy plantations involves $x/acre in coppiced fuel, $1000/acre in nuts, and $2k/acre in sustainable chickens that fertilize the crop via autonomous chicken tractors.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
==Heat Exchanger==&lt;br /&gt;
&lt;br /&gt;
The heat exchanger is a device that takes heat from one medium and puts it into another. For example, in the Seed Eco-Home - we have a hydronic stove with heat exchanger which is used to heat water for heating the house.&lt;br /&gt;
&lt;br /&gt;
Fig. Hydronic stove with heat exchanger. A heat exchanger heats water, and if that water is boiled, it can be used to run a steam engine or turbine. Small steam engines have been used for shop power 100 years ago, and they can be used even more effectively today. You can get a working kit for $275 on Ebay.&lt;br /&gt;
&lt;br /&gt;
Simpler examples of the heat exchanger are the Hillbilly Heater. This device traps solar heat and puts it into water circulating through the black tubing. This energy is released through another coil in the aquaponic ponds, for example. A closed heat exchanger means that the water in the black tubing does not mix with the pond water. Or, this heat exchanger could be an open heat exchanger, where the water is heated and then used as hot water in a shower - so that a steady supply of new water is fed through the exchanger instead of just circulating - as in the pond heating case.&lt;br /&gt;
&lt;br /&gt;
Fig. The hillbilly heater can be used to heat ponds or to provide hot water for the house.&lt;br /&gt;
&lt;br /&gt;
==Modern Steam Engine==&lt;br /&gt;
&lt;br /&gt;
The modern steam engine is an engine that produces power from steam. The industrial economy was created by steam power. And steam turbines are the main way that power is generated today. &lt;br /&gt;
&lt;br /&gt;
A modern steam engine is a small engine that makes sense to build wherever space heating is involved. For example, a centrally heated building could be generating power at the same time as its being heated - if a heat engine with a generator is added to the system. Thus, we are piggy-backing on an existing power source, while using all the waste heat.&lt;br /&gt;
&lt;br /&gt;
Under 500 hp - or in any small scale installation - it is more effective to have a steam engine as the engine of choice. Above 500hp, it is more effective to use a steam turbine. Large power plant steam turbines reach 50% efficiency. https://en.wikipedia.org/wiki/Steam_turbine#Practical_turbine_efficiency &lt;br /&gt;
&lt;br /&gt;
A flame-fired or solar-powered heat exchanger can produce steam - for electricity generation. This makes sense for combined-heat-and-power systems. Most of today’s electricity is produced by water that is boiled in power plants to provide electricity via steam turbines. (ref) This can be done effectively on a scale of 500 or more horsepower - which is village scale, not home scale. For the smaller scale, a small steam engine can be used. For this reason, we have incorporated a modern steam engine into the GVCS - as a machine for producing electricity on top of a heat source. This could be done in our hydronic stove - where the water goes from the steam engine and then to house heating after some power has been extracted for electricity. It makes sense to convert the heat into high grade electricity - when the steam engine is connected to a generator.&lt;br /&gt;
&lt;br /&gt;
Fig. Hydronic stove with power generation.&lt;br /&gt;
&lt;br /&gt;
Did you know that the modern steam engine - a specific advanced version -  is more efficient than the internal combustion engine? The Cyclone engine is a high tech, high temperature steam engine made of stainless steel and exotic materials - with thermal efficiency over 30%. http://cyclonepower.com/ &lt;br /&gt;
&lt;br /&gt;
There is another steam engine that received a lot of attention on the internet but appears not to work well - the Green Steam Engine. We do not endorse the engine, as suggested by Tom Kimmel of Kimmel Steam Power  http://kimmelsteam.com/green-robertengine.html  - and you can read more in an old blog post. (http://opensourceecology.org/steam-meet-report/ . I have since contacted Mr. Greene for data on Feb 1, 2018, but I have not been presented with any data.)&lt;br /&gt;
&lt;br /&gt;
All together, the modern steam engine is valuable for household power, if the Power Cube is used for mobile power. Would would be the cost of a steam engine add-on to a household infrastructure? Small models of ¼ hp are available for under $300 in parts, (http://ebay.to/2EwmHWt ) and these are scalable readily to larger sizes. The current seed eco-home stove has sufficient power to run this engine, so only an additional pump would be required to feed water to this system.&lt;br /&gt;
&lt;br /&gt;
Integration of such a system would work well if pelletized biomass were used as fuel - and subsequently - charcoal would be produced for use in cars as a byproduct of household power generation. An interesting milestone would be an automated biomass energy system from an autonomous tractor-pelletizer - up to the production of charcoal as car fuel using gasifiers - all from one’s former lawn converted to bioenergy crop.  In such case, nickel iron batteries may be desirable in so far as excess energy storage from daytime solar power.&lt;br /&gt;
&lt;br /&gt;
Fig. The energy product ecology of the Seed Eco-Home includes solar hydrogen, biogas for cooking, and production of car fuel from the lawn.&lt;br /&gt;
&lt;br /&gt;
==Solar Concentrator==&lt;br /&gt;
&lt;br /&gt;
The modern steam engine equation becomes much more exciting when solar concentration is used. Using 30% efficient, modern steam engines, proven linear solar concentrators, and a night-time storage system based on large, insulated propane tanks with hot water - it is possible to produce an off-grid energy system with $100/kWhr energy storage costs - 4x cheaper than lithium ion batteries. https://en.wikipedia.org/wiki/Lithium-ion_battery  A breakthrough company - Terrajoule - has already demonstrated this. Then the question becomes - if this has already been shown in the first prototype of Terrajoule, why isn’t everyone doing this when the technology is all proven? One cannot beat the simplicity of water and solar heat as the ultimate storage medium. &lt;br /&gt;
&lt;br /&gt;
What can water really do? When water is heated but not allowed to expand, it turns to what is known as saturated water. A saturated liquid is a liquid whose temperature and pressure are such that any decrease in pressure without change in temperature causes it to boil. In other words, if a tank was not holding the water at pressure - that water would turn into steam.&lt;br /&gt;
&lt;br /&gt;
Just how much energy can that water store at a medium pressure? A lot. Looking at the total heat content of water that would otherwise turn to steam, but is held under pressure at 18 atmospheres (250 PSI) in a tank instead http://opensourceecology.org/wiki/Saturated_Water  - we see that each kilogram of such saturated water holds about ¼ kWhr of energy. That means that a 10,000 gallon propane tank can store about 4MWhr of energy! We can extract that energy with a modern steam engine, where steam engines from the 1950s got to about 30% efficiency. https://en.wikipedia.org/wiki/Uniflow_steam_engine   After all the losses, we we would have 300kWhrs of electricity when the modern steam engine runs a generator.&lt;br /&gt;
&lt;br /&gt;
We can scale that down to a residential system - just a 1000 gallon propane tank - and 30kWhrs of electricity produced.&lt;br /&gt;
&lt;br /&gt;
Fig. Cost and energy of a home-scale solar energy storage system using water and modern steam power. From energy content of 400kWhrs to 30kW hours of electricity is quite doable using proven technologies, at ¼ the cost of battery storage.&lt;br /&gt;
&lt;br /&gt;
==Nickel Iron Battery==&lt;br /&gt;
&lt;br /&gt;
Nickel-Iron Batteries are long-life batteries that have a track record of lasting 50 or more years. Unlike other batteries, these can be discharged fully without decreasing their lifetime. These are chosen for the Global Village Construction Set specifically for their long life - and becuase nickel and iron are not scarce resources. While heavier and 2x more expensive than lithium ion batteries, (Read an intereresting pro-con discussion - http://opensourceecology.org/wiki/Nickel_Iron_vs_Lithium_Ion_Battery_from_Tesla_Motors ) they make up by their long lifetime, and lend themselves to decentralized production. New developments are in progress, ( https://news.stanford.edu/news/2012/june/ultrafast-edison-battery-062612.html )  though OSE does not rely on new developments for feasibility given that OSE internalizes social and environmental aspects for true cost accounting. The cost is currently high because production volume is low - only 2 US manufacturers. Based on a nickel price of $6/lb and iron at 25 cents/lb, and a weight of 100 lb for 1kWhr - and a 20% content of nickel in nickel iron batteries https://www.solarpaneltalk.com/forum/off-grid-solar/batteries-energy-storage/ni/7052-how-much-nickel-is-really-in-a-ni ckel-iron-ni-fe-battery - the base materials cost of materials in Nickel Iron batteries appears to be $150/kWhr. That is similar to lead acid batteries and ½ of lithium ion costs - but if the lifetime of these batteries is really 50 years, then they are 5-10x cheaper than other batteries based on lifetime.&lt;br /&gt;
&lt;br /&gt;
According to recent research: https://link.springer.com/content/pdf/10.1007/s10800-015-0911-3.pdf &lt;br /&gt;
&lt;br /&gt;
There are many reasons favouring the use of NiFe cells as cost-effective solutions to store grid-scale amounts of energy, such as low cost of raw materials, environmental friendliness, electrical abuse tolerance, long life (in the order of thousands cycles of charge and discharge) and compatibility with photovoltaics (PVs). Due to the nature of the heavy metals involved in its construction this technology is suitable for stationary low gravimetric energy applications (30–50 Wh kg-1 ). As a consequence, there are good reasons to foresee a large scale utilization of this technology. Due to their outstanding safety properties (zero flammability, fail safe, no over/ under charge), low cost and long lifetime, we anticipate that they will receive widespread public acceptance for customer-connected energy storage.&lt;br /&gt;
&lt;br /&gt;
It is our hope that the nickel iron battery would be only a small fraction of electrical power storage needs in the future - such as replacing 5-year lifetime starter batteries in vehicles. For night time electricity, it would be useful for warmer regions to use solar concentrator saturated water storage - as one possibility - or solar hydrogen as another.&lt;br /&gt;
&lt;br /&gt;
In colder areas, biomass is typically available as an abundant energy crop - where PV may not be adequate if there are weeks without sun. The exact mix of solar concentrator electric, PV, wind, charcoal, biomass, biogas, and hydrogen is to be determined at Factor e Farm as we measure the value of all these systems side by side. The main requirement for OSE is true service to humanity, environmental regeneration, and freedom from resource conflicts.&lt;br /&gt;
&lt;br /&gt;
==50 kW Wind Turbine==&lt;br /&gt;
&lt;br /&gt;
A wind turbine converts a renewable form of energy - wind - into electricity. It provides a good backup to PV electricity, as wind typically blows when the sun is not out.&lt;br /&gt;
&lt;br /&gt;
We propose a vertical axis wind turbine for the initial OSE version based on integration with hydraulics and the Universal Rotor.  A simple system can consist of a pole mounted 40 hp hydraulic motor ($400), serving as a pump - which transfers fluid power to an on-the-ground hydraulic motor ($300) + 24 kW generator ($1000). The power generator related costs are ~ $2000 here, and the rest is the tower and structure. With $6k spent on the materials for this wind turbine, this would be $250/installed kW in materials costs - with installation being 15% on top of this http://www.esru.strath.ac.uk/EandE/Web_sites/14-15/XL_Monopiles/cost.html  - a very attractive package in a sweet spot of cost for readily-available components. This is compared to $1590/kW standard costs of large scale wind installations. https://www.awea.org/falling-wind-energy-costs &lt;br /&gt;
&lt;br /&gt;
The OSE design features a generator that is mounted on the ground, with only the hydraulic motor on top of the tower. This facilitates maintenance considerably. The savings is due in part to the great simplification of the nacelle - in the OSE case, the vertical axis design doesn’t have a yaw mechanism - it’s just a hydraulic motor that accepts wind from any direction. These turbines are not as efficient in terms of wind capture as they are lower to the ground - but the low capital + maintenance costs make up for the lower efficiency. Because they can be packed more tightly in the same area, however - VAWT wind farms can actually produce 10x the energy of a propeller-type wind farm. https://en.wikipedia.org/wiki/Vertical_axis_wind_turbine#Advantages  They also self-regulate their speed, so they do not need a braking meachanism for overwind conditions.&lt;br /&gt;
&lt;br /&gt;
Fig. OSE VAWT concept. Simplification of design include ground-mounted generator, yawless rotor, screw pile foundation https://en.wikipedia.org/wiki/Screw_piles#Modern_Use_and_Benefits  , and braking via the hydraulic motor as the overspeed protection. The wind turbine module is designed for 24 kW, and it includes the Electric Motor/generator, Universal Rotor, Hydraulic Motor, Power Cube, and Universal Power Supply for managing power.&lt;br /&gt;
&lt;br /&gt;
8. Universal Power Supply&lt;br /&gt;
The Universal Power Supply (UPS) is the last of the energy machines. It is a universal device for powering large electronic machines - induction furnaces, welders, plasma cutters, laser cutters - and for controlling power delivery and transmission to homes or electric cars. It is also used for charging. The UPS has feedback such that it would know when batteries are full, or for optimizing the power transfer into a load of metal that is melted with the induction furnace. &lt;br /&gt;
&lt;br /&gt;
The Universal Power Supply in general  converts AC and DC into voltages and currents of any amplitude and frequency. The UPS is scalable from a few watts to 20kW based on the same design of modules.  The Universal Power Supply can also be used to condition power from the wind turbine or PV system and pump it into the grid. It can also be used as an inverter to convert DC to AC, or it can be used to control the speed of an electric car. It can also be used to step power up to high voltage for power transmission over longer distances, such as up to the 69,000 volts for rural power lines. &lt;br /&gt;
&lt;br /&gt;
As with the mechanical machines, the Universal Power Supply is based on modular design, such that we can arrive at a Construction Set. Just like power units, wheels, shafts, hydraulic motors, control valves, and frames can create any mechanical industrial machine, so can a small number of modules provide just about any electrical power function in the Universal Power Supply. These modules are mainly: a microcontroller, a current measurement device, a transistor, wires, laminated cores, ferrite beads,  diodes, optocouplers, resistors, capacitors, and inductors - plus a few mechanical components such as plugs, cases, cooling systems. With advanced transistors that now cost $1 per kW of power handling, large power electronic devices can be built on the cheap if open source knowhow is available.&lt;br /&gt;
&lt;br /&gt;
Wires and metal cores themselves produce a wide range of devices: inductors, transformers, relays, solenoids, switches for large currents, electric motors, spark generators, electromagnets, and other devices. &lt;br /&gt;
&lt;br /&gt;
Lasers, charge controllers, inverters, welders, induction furnaces, plasma cutters, oxyhydrogen generator power supply, and motor controllers are all functions that can be generated with the Universal Power Supply. These are all based upon currents and voltages at different frequencies and amplitudes that perform radically different functions. This has to do with the nature of electricity - jus like a few atom types (100 or so) make up millions of different substances that are all around us - so can electricity be manipulated to perform a wide array of functions. Any of the above devices consist of a microcontroller and a power transistor - along with some resistors, capacitors, and inductors. The microcontroller could be an Ardduino or a Rasperry Pi - which now cost as little as $5 for these small computers running with a 700MHz cpu. This CPU - via software - can produce a voltage of any amplitude and frequency using transistors. In other words - a ‘brain’ - the CPU - can massage electrons so they maifest at any voltage or frequency - by using transistors - or devices where a small signal from a CPU controls a large voltage. Essentially - a transistor is a switch - which is activated by a small signal.&lt;br /&gt;
&lt;br /&gt;
For example - taking DC voltage - one can make it pulsed and appear as an oscillating sine wave. This is an inverter for household power - which can for example take electricity from PV cells and convert that into household current. Or - this same inverter can be pulsed much faster to create a 30kHz voltage used in an induction furnace. And regulation can happen - such as an induction furnace delivering power most effectively to the molten charge - when the same microcontroller can measure the voltage, and change the frequency of the applied voltage to pump power more effectively into the melt. &lt;br /&gt;
&lt;br /&gt;
This is all possible because superfast microcontrollers, and high power handling transistors - can all be purchased now for a few dollars.&lt;br /&gt;
&lt;br /&gt;
Energy Summary&lt;br /&gt;
&lt;br /&gt;
Combining biomass, charcoal, biogas, wind power, the solar concentrator,  steam electricity, hydrogen, PV - and the electronic controls of the Universal Power Supply -  makes for a resilient power infrastructure without necessitating resource conflicts.&lt;br /&gt;
&lt;br /&gt;
=Open Source Microfactory=&lt;br /&gt;
&lt;br /&gt;
The Open Source Microfactory (OSM) is the crown jewel of the Global Village Construction. It is the part that allows for GVCS self-replication - in that the Open Source Microfactory allows for the production of all the  GVCS tools - including the Microfactory itself..&lt;br /&gt;
&lt;br /&gt;
The Open Source Microfactory is broken into 2 main parts: precision CNC tools, and metal production tools. The CNC tools - which stands for Computer Numerical Control - are automated machines that can be programmed to build things - from small parts, to engines, and everything in between. The metal production tools allow for the production of virgin steels from scrap. The steel that can be produced with the GVCS metal tools thus allows for the creation of advanced civilization - wherever there is access to scrap steel. Scrap steel is abundant, and so it iron ore from which steel is made. Iron is the 4th most abundant element in the earth’s crust - after oxygen, silicon, and aluminum. https://en.wikipedia.org/wiki/Abundance_of_elements_in_Earth%27s_crust &lt;br /&gt;
&lt;br /&gt;
What if there is no scrap steel available? We can go to aluminum - which is even more abundant in terms of the crust’s composition. Aluminum is found in common clay. Clay is aluminosilicate, from which aluminum can be extracted. Because Aluminum is so abundant - the GVCS goes so far as the extraction of aluminum from clay. This is intended to break through any notions of scarcity in today’s civilization.  Clay is abundant, and it’s an essential part of the GVCS: compressed earth blocks, soil for growing food, clay for 3D printed pots and cookware - in addition to the production of aluminum metal.  &lt;br /&gt;
&lt;br /&gt;
Fortunately - silicon is even more abundant. We get solar cells for producing electricity from silicon - a core technology for the GVCS such as in the Seed Eco-Home. In less than the time it takes to read this paragraph, the sun will have provided as much energy to Earth as used by all of human civilisation in one day. Thus silicon solar cells are important. And silicon is used to make semiconductors - so silicon creates the computer age.&lt;br /&gt;
&lt;br /&gt;
With the Open Source Microfactory - we thus aim to show that literally, modern civilization may be created -  from dirt and twigs. This can happen on any parcel of land - as solar cells can easily produce about 500kW of energy - from an acre. So a facility such as the OSE headquarters can produce all the technology required to produce an advanced civilization. For example, 500kW of solar energy - or 3MWhrs per 6 hours of daylight - can produce 200 kg of aluminum per day. Aluminum requires 15 kWhr per kilogram to smelt. (http://wordpress.mrreid.org/2011/07/15/electricity-consumption-in-the-production-of-aluminium/ . This one says ,05 GJ/kg - http://wordpress.mrreid.org/2011/07/15/electricity-consumption-in-the-production-of-aluminium/ )Aluminum is energy intensive - but its production may one day be improved for more environmentally-sound production - as can any other process by internalizing environmental costs.  https://www.sciencedirect.com/science/article/pii/S0360544207001065#! &lt;br /&gt;
&lt;br /&gt;
This shows how energy intensive aluminum production is - but its 3x better weight to strength ratio compared to steel makes it a desirable product. With the proposes 200kW solar microfactory - we can produce 80 kg of aluminum per day. That’s not a lot - but acceptable as a proof of concept for an appliance-size machine.&lt;br /&gt;
&lt;br /&gt;
Aluminium is the most abundant metallic element in the Earth’s crust (about 8%) and the&lt;br /&gt;
second most widely used metal next to steel. The aluminum production process involves taking ordinary clays such as abundant kaolin clay - and leaching out alumina with hydrochloric acid to produce Al203, which is subsequently turned to Aluminum via electrolysis at a cost of 15 kWhr per kg of aluminum produced. For reference in terms of energy requirements - this is like converting one gallon of gasoline to one kg of aluminum. That’s a lot of energy. But the main point here is that this can be done anywhere where there is soil - clay for making aluminum is an abundant feedstock.&lt;br /&gt;
&lt;br /&gt;
If we talk about the carbon dioxide emissions - whether from aluminum or steel production - the way we propose to make it sustainable is to make the CO2 recyclable. If the carbon involved in the reactions for producing metals - or for that matter any other product - comes from charcoal derived from biomass - then the industrial process is regenerative as the plants that were used to produce the charcoal took the carbon out of the atmosphere in the first place. Thus, a sustainable industry is possible  when civilization evolves to using charcoal  instead of fossil fuels. &lt;br /&gt;
&lt;br /&gt;
However, it should be stated that CO2 in the long run may be more advantageous for ecology - even from fossil fuels - if that CO2 yields more plant growth. While many people see CO2 per say as a global warming problem - it is also possible that the CO2 will make the earth more green. Nobody knows what will happen at this point - we can only speculate as to the long term effects of increasing CO2 in the atmosphere. &lt;br /&gt;
&lt;br /&gt;
The open source microfactory is intended to produce an entire technosphere from local resources, pushing the limits of what can be done:&lt;br /&gt;
&lt;br /&gt;
Fig. Open Source Microfactory cyclic material flows can be based on local resources. Metals, bioplastics, ceramics, PV cells, concrete, carbon, hydrogen, glass, rubber, fuels, food, construction materials, and many other chemicals can be produced from local abundance.&lt;br /&gt;
&lt;br /&gt;
If it is indeed that PV cells can be made from local sand, and aluminum from clay - and everything else as noted - then we have truly stepped into a world of post-scarcity. At the point where material production is guaranteed, it may be possible for people to evolve full time - without being held back by mere survival. That is the essence of society that OSE intends to create - one in which material needs are not in the way of human evolution.&lt;br /&gt;
&lt;br /&gt;
For any other processes of industry - the Open Source Microfactory can provide. If you can make buildings, glass, metal, and plastics + other materials - you can build anything. Advanced processes such as chemical plants or semiconductor fabs - are nothing but buildings, metal vessels, motors, vacuum pumps, and a few other basics - and from there spews out any product - in a nutshell. This does not even involve the nanotech of molecular manipulation - where it is deemed that in the future we will be able to synthesize substances by moving atoms directly - without regard for chemical reactivity as we know it today. Yet we do not invoke the Technological Singularity as a prerequisite for meeting all human needs.&lt;br /&gt;
&lt;br /&gt;
Let’s move to the specific tools in the Open Source Microfactory:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
And &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Fig. Tools of the Open Source Microfactory. They include everything needed to produce precision metal parts starting from scrap metals, glass, bioplastics, and even semiconductors for solar cells. &lt;br /&gt;
&lt;br /&gt;
==Universal Axis==&lt;br /&gt;
&lt;br /&gt;
Six of the Open Source Microfactory tools are based on the Universal Axis. The Universal Axis is a modular, and scalable CNC axis which can be used to create cartesian CNC machines. The core of the axis design is belt drive and linear motion rods where carriages are pulled on the rods. The system is scalable to any size and number of axes, including rotary axes. The system uses a combination of 3D printed parts, metal plates, and belt-driven shafts. Applications include 3D printers, CNC torch tables, heavy duty CNC machines, and many other production machines.&lt;br /&gt;
&lt;br /&gt;
We intend to use the 5/16”, 1”, and 2” versions for 3D printers, CNC torch tables, and heavy duty CNC machines - which are among the key machines that can be built with the system - though a variant of any size and shape can be designed.&lt;br /&gt;
&lt;br /&gt;
Fig. The universal axis comes in 5/16”, 1”, and 2” variations, and is based on belt drive, though a screw and nut system can also be used as a drive. Various tool heads can be attached. Non-contact tool heads are attached magnetically, such as the laser cutter and 3D printer. Rotary attachments can even be used for 3D scanning or indexing.&lt;br /&gt;
&lt;br /&gt;
For heavy duty applications, the plastic plates may be reinforced with steel plates - making a steel-plastic composite that has the required strength - while being easy to produce because the complex geometry is 3D printed. The metal plates themselves can be CNC cut using the CNC torch table. This allows for the lowest cost route - the 2” bushings capable of 8000 lb force on these axes currently cost only $9.41 at McMaster Carr.&lt;br /&gt;
&lt;br /&gt;
Fig. Metal-plastic Universal Axis System.&lt;br /&gt;
&lt;br /&gt;
The power of the universal axis lies in its flexibility. The same design of the drive system can be used to make an unlimited range of fabrication machines, putting the manufacturing process completely in the hands of anyone - without high barriers to entry. This is aimed at the Open Source Microfactory in every town, where our goal is to distribute at least 10,000 of these open source microfactories around the world, each generating at least $100,000 of net revenue per year. Once production returns to communities, we expect that taxes will go down as communities once again become responsible for their own prosperity.&lt;br /&gt;
&lt;br /&gt;
==The 3D Printer, Bioplastic Extruder, 3D Scanner==&lt;br /&gt;
&lt;br /&gt;
The 3D printer is a machine with diverse applications. Essentially, the technosphere is made from plastics, ceramics, and metals. 3D printers can print with all of these, and are as such ubiquitously applicable to manufacturing of all sorts. Currently, it is easy to print with all kind of plastic, including rubber for printing tires and polycarbonate for printing glazing. It is likewise easy to print ceramics - by printing clay and then baking it. Here we can produce ceramic cookware or clay parts such as insulators or building bricks. If the clay contains a large fraction of glass or metal - then upon kilning - 3D printed glass and metal objects can be printed as well. Metal printing can also happen via a MIG or TIG welder as the working toolhead - where large metal structures can be printed additively like this. If we go a step up to lasers - we can do selective laser sintering of any kind of powder - from plastic, to ceramic, to metal. Extremely strong, precise metal parts can be created this way - such that for example the rocket engine for Elon Musks’s SpaceX rockets has been 3D printed.&lt;br /&gt;
&lt;br /&gt;
Fig. Different applications of 3D printing: plastic, rubber, glass, metal, ceramic, and housing.&lt;br /&gt;
&lt;br /&gt;
Carbon fiber or metal fibers can also be embedded in plastic 3D prints to make the parts as strong as aluminum. 3D printing can also print ceramic molds which can then be used for casting directly into these molds - using either molten metal from an induction furnace or a MIG weld right into the metal form.&lt;br /&gt;
&lt;br /&gt;
Fig. Apparatus for automated metal casting using 3D printing of molds + induction heating of melt to fill the molds.&lt;br /&gt;
&lt;br /&gt;
Currently - open source printing includes  plastic + rubber 3D printing, welder 3D printing, clay printing for ceramics, clay-metal 3D printing for metals, selective laser sintering of plastics, and 3D priting of concrete or clay buildings. With a little bit of work,  the full printing with metal or glass using selective laser sintering can be developed by using off-the-shelf technologies. An 80W laser tube like in the Laser Cutter + shielding gas allows for selective laser sintering of off-shelf metal powders. http://opensourceecology.org/wiki/Metal_Selective_Layer_Sintering#Literature &lt;br /&gt;
&lt;br /&gt;
Fig. If metal powder is available (it is, such as iron at $1/lb) - then we can use a laser to fuse a powder bed to complex 3D objcts that cannot be produced in any other way.&lt;br /&gt;
&lt;br /&gt;
The world of 3D printing is in its infancy - and this is definitely worth refining to achieve full 3D printability in any material. Perfecting all of the above 3D printing can go far towards local production of just about anything.&lt;br /&gt;
&lt;br /&gt;
==Bioplastic Extruder==&lt;br /&gt;
&lt;br /&gt;
The Bioplastic Extruder is part of a system that enables the production of biodegradeable bioplastics from natural feedstocks such as cellulose or sugars. The system includes 3D printing filament production as well as direct extrusion of useful parts.  &lt;br /&gt;
&lt;br /&gt;
Four main aspects are involved in the Bioplastic Extruder System. First, a bioplastic reactor is used to make bioplastic from abundant biological feedstocks such as cellulose, sugar, or starch. Second - once the plastic is produced - or is available from the waste stream - it can be extruded with the Bioplastic Extruder to make 3D printing filament. Third, the 3D printing filament is then used directly in 3D printers to make useful objects. Fourth, other useful products can be made with the extruder: plastic lumber, which can be made from recycled plastic and sawdust. This could be a great way to recycle plastics into durable construction materials. Other useful profiles - such as tubing and glazing panels - can also be produced with the bioplastic extruder. Thus, the bioplastic extruder per se can be used for 2 main purposes: making 3D printing filament as an intermiediate feedstock for 3D printers - or extruding useful products directly.&lt;br /&gt;
&lt;br /&gt;
Fig. The bioplastic production system of the GVCS consists of bioplastic synthesis followed by extrusion to produce 3D printing filament, tubing, sheets, or plastic lumber. 3D printing filament can be used for 3D printing. Thermoplastic elastomers - or rubber - can also be printed.&lt;br /&gt;
&lt;br /&gt;
There are 3 types of bioplastics - those derived from: (1) petroleum and biodegradeable; (2) biomass and biodegradeable; and (3) biomass and non-biodegradeable. OSE is most interested in bio-based, biodegradeable bioplastics, as the feedstocks are most widely available and can be produced ecologically anywhere in the world. &lt;br /&gt;
&lt;br /&gt;
The OSE bioplastic system allows for local recycling such that the plastic never ends up in the landfill - but is either reused or recycled. By eliminating plastic waste and turning it into valuable products, wealth can be multiplied. Also, we can clean up the environment by reusing plastics - which can otherwise persist in the environment for 1000 years. Such recycling also reduces the need for petroleum - the typical feedstock of plastics.&lt;br /&gt;
&lt;br /&gt;
Bioplastics derived from biomass that are non-biodegradeable can be produced from petroleum substitutes. Petroleum can be replaced with charcoal. As such, any plastic typically derived from petroleum can also be produced from renewable, plant-derived charcoal. In the OSE system, plant matter is pelletized, then burned partially for space heating or process heat - with the byproduct being the important charcoal feedstock. If one is interested in replacing petroleum-derived chemicals - charcoal is first burned in a gasifier to produce CO and H2 - just as the gasifier fuels regular engines with CO and H2 - a combustible mixture. Instead of being burned in an engine as a renewable fuel, these molecules can combine under heat and pressure and an iron catalyst to produce long hydrocarbon chains and water. The long chains are alkanes - the typical long-chain molecules of -[CH2]- found in petroleum. This conversion process is known as Fischer-Tropsch synthesis, and is important from the abundance mindset - in that all products than now come from coal and petroleum can be made more ecologically - from plants. https://en.wikipedia.org/wiki/Fischer%E2%80%93Tropsch_process  &lt;br /&gt;
&lt;br /&gt;
Fig. The circular economy of OSE is based on wood - to make charcoal, paper, bioplastic, rubber, and fuel.&lt;br /&gt;
&lt;br /&gt;
Cellulose acetate is a bioplastic that is easily made from the most abundant organic polymer in the world - cellulose. It can be made readily from trees. Did you know that wood fibers can be converted to this bioplastic by reacting these fibers - with glacial acetic acid? The product is 3D&lt;br /&gt;
&lt;br /&gt;
printable.http://www.designforcraft.com/new-materials-for-3d-printing-cellulose-acetate/  You can make windows with it.http://nvlpubs.nist.gov/nistpubs/jres/19/jresv19n4p367_A1b.pdf  Instead of trees, one can use any source of cellulose - paper, cotton, straw, or other cellulose materials. &lt;br /&gt;
&lt;br /&gt;
Straw and wood are thus very important in the overall product ecology for making fuel pellets, insulation for the Seed Eco-Home (with borax), strawboard, charcoal, paper,  steel (charcoal with iron ore), and bioplastics.&lt;br /&gt;
&lt;br /&gt;
Polylactic Acid, or PLA, is the most popular bioplastic used in 3D printing. It can be derived from bacterial fermentation of sugar - and is thus an accessible technology within the GVCS.&lt;br /&gt;
&lt;br /&gt;
Polyhydroxyalkanoate (PHA) or polyhydroxybutyrate (PHB) bioplastic polyesters are considered the best candidates to replace the current petroleum-based plastics due to their durability in use and wide spectrum of properties. https://www.intechopen.com/books/biotechnology-of-biopolymers/conversion-of-biomass-into-bioplastics-and-their-potential-environmental-impacts  They are made by bacteria from sugar or starch at an efficiency of up to 80% of bacterial cell mass.https://www.intechopen.com/books/biotechnology-of-biopolymers/conversion-of-biomass-into-bioplastics-and-their-potential-environmental-impacts  Some PHAs are elastomers. Thus - it is realistic to include rubber production for tires - from sugar or starch - within the industrial ecology of the GVCS. Unlike latex resin from dandelion roots - which can be used to produce thermoset plastics - PHA rubber is thermoplastic, so it can be recycled easily. Both PHA rubber and dandelion root rubber can be grown anywhere - thus removing the strategic importance of tropical rubber tree plantations. It appears that PHA rubber is more viable from the decentralization perspective. Wood, broken with acid to simpler sugars - can also be used a feedstock for PHA - thus making PHA rubber production possible anywhere in the world. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4964529/   However, woody crop can compete with food crops - so we once again emphasize perennial polycultures as ways to produce food, fuel, and fiber. With perennials, it is also easier to use degraded lands, which can be regenerated back to fertility and health when annual crops are removed from the equation.&lt;br /&gt;
&lt;br /&gt;
In addition to sugar and cellulose, starch from common sources such as potatoes or corn can be polymerized readily in the kitchen. For example, mixing vinegar and glycerine with the starch makes a bioplastic.http://opensourceecology.org/wiki/Starch_Bioplastic   This is the easiest route  that can be used for 3D printing&lt;br /&gt;
&lt;br /&gt;
The bioplastic extruder has 2 main functions: one is to perform extrusions directly - or to produce intermediate 3D printer filament which is then used to 3D print final objects. For the latter, we are currently building upon two open source projects working on plastic extruders: the Lyman Filament Extruder,http://opensourceecology.org/wiki/Lyman_Filament_Extruder  and the Thunderhead Filament Extruder from Tech For Trade.http://opensourceecology.org/wiki/TechforTrade  These are simple versions of plastic extruders - which if scaled up and made more robust - can produce not only 3D printing filament, but larger extrusions.&lt;br /&gt;
&lt;br /&gt;
==3D Scanner==&lt;br /&gt;
&lt;br /&gt;
The 3D scanner allows for scanning of 3D objects to produce Computer Aided Design (CAD) models for reverse engineering. This is very useful - as we can take existing parts and digitize them for use as editable CAD models. A single camera can be used for photogrammetry, which is a computational technique for converting a set of pictures of an object taken from multiple angles into a 3D object.http://opensourceecology.org/wiki/Open_Source_Photogrammetry There is a number of open source programs that can do this. A 3D digital object can also be generated using multiple cameras, laser beams, or other light sources reflected from an object. As the simplest route, OSE  will build on existing work to develop the toolchain and procedure for photogrammetry - as that requires no hardware outside of a simple camera and a computer to process the images. If markers are used on objects, accurate CAD can be generated with proper dimensions. &lt;br /&gt;
&lt;br /&gt;
It gets more interesting: we can 3D scan internal features, too. This is known as industrial Computed Tomography (CAT) - essentially - a CAT scan for metal objects. By using an x-ray or gamma ray source - and then photographing an image - we can build a low-cost DIY CAT scanner.https://www.youtube.com/watch?time_continue=25&amp;amp;v=hF3V-GHiJ78  http://www.tricorderproject.org/blog/tag/openct/  Combined with an open source code base for image processing  from CERN, 3D industrial tomography scans can be obtained.https://home.cern/cern-people/updates/2016/09/new-open-source-medical-imaging-tools  &lt;br /&gt;
&lt;br /&gt;
==CNC Circuit Mill + Small Laser Cutter==&lt;br /&gt;
&lt;br /&gt;
We have already prototyped a circuit mill - the D3D CNC Circuit Mill.http://opensourceecology.org/wiki/D3D_CNC_Circuit_Mill  This shows a great example of the Unversal CNC axis modularity - where we have used the same motion system as in the 3D printer - but now strengthened the motion system by doubling the x axis to hold a small router. While the 3D printer is a non-contact manufacturing method - the circuit mill requires that the axes withstand contact forces of the milling operation. The strong, steel space frame of the D3D platform can handle these forces.&lt;br /&gt;
&lt;br /&gt;
Furthermore, other tool heads can be used on the Universal Axis. One useful example is a small 4W laser cutter, which cut up to ¼” plywood for prototyping purposes.&lt;br /&gt;
&lt;br /&gt;
Fig. The OSE CNC circuit mill and example circuits produced. The Router Tool Head is one of many tool heads that can be used on the Universal Axis system. A small laser is another, and can be retrofitted readily. The laser cutter toolhead allows for cutting cardboard for rapid prototyping. (4-picture - mill+product, laser+product)&lt;br /&gt;
&lt;br /&gt;
Prototyping with a laser cutter is important to the GVCS because the laser cutter can simulate the cutting that is typically done with a CNC torch table. Just like the CNC torch table typically cuts ½” thick flat parts out of sheet steel - the small laser cutter can cut parts out of paper stock. These parts can then be glued or fit together - just like the CNC-torch-cut metal parts are welded to make real-life 3D machines such as the CEB Press.&lt;br /&gt;
&lt;br /&gt;
Fig. Flat metal is used to generate 3D objects by welding. We thus use 2D cutting to create 3D objects.&lt;br /&gt;
&lt;br /&gt;
An open source project for a larger laser cutter - the 100W Lasersaur - is already well-developed. We can use this platform to build upon as well, to reduce cost from its current $7k to something more on the scale of $3k for a large format laser cutter. The Universal Axis could be applied here, such that only the laser system ($2000) remains as a significant cost - and the rest of the system is ($1000). This would be another great application of the Universal Axis to show its flexibility.&lt;br /&gt;
&lt;br /&gt;
Another useful example of a practical tool-head is a ceramic 3D printer head - which is an extruder for clay materials that can be fired to make functional ceramics. Examples of very useful ceramics are insulators and pottery - especially stovetop cookware made of flameware clay - which can replace commercial cookware and provide artistry in the open source Seed Eco-Home kitchen.&lt;br /&gt;
&lt;br /&gt;
Fig. The ceramic print head allows for the production of practical objects such as pots and pans for cooking, bringing artistry back into the kitchen.&lt;br /&gt;
&lt;br /&gt;
Collaborative Prototyping + Model Kits + Product Ideas + The Open Source Everything Store&lt;br /&gt;
&lt;br /&gt;
With access to the OSE Developer Kit - 3D printer, CNC Circuit Mill, and Laser Cutter - all as different tool heads on the same Universal Axis system - collaborators access a powerful capacity to prototype the larger machines of OSE. Using these tools, accurate scale models can be built. This can extend the collaboration capacity on OSE machine development significantly. There are 4 major ways that collaborative prototyping can be done using the 3-in-1 Universal Axis machine. &lt;br /&gt;
&lt;br /&gt;
First, there is collaboration is CAD verification. Computer Aided Design (CAD) is used in the OSE design process in order to save countless hours during the build. In a proper design process, it is easier to design in virtual CAD - and figure out how everything fits together - rather than going straight to a build and having to fit everything on the fly. The ability to model accurately in CAD is the power that allows OSE to do builds on the scale of a day - as opposed to weeks. However - this works only if the CAD is accurate, because if the CAD drafting is not accurate, it may be impossible to build a machine. CAD quality depends on the skill of the draftsperson. For this reason, it is important to verify the CAD as one of the steps that takes place prior to a build. If mistakes are not caught prior to the build, time and materials are wasted, people can get frustrated, and schedules are delayed.&lt;br /&gt;
&lt;br /&gt;
How do we guarantee that a machine can be built as drafted? With an accurate scale model. First, we must make sure that the CAD of individual parts is correct. This can be assured when accurate CAD files are available - whether the files are generated from measurements, provided by manufacturers, or 3D scanned with the open source 3D scanner. Second, we can verify the actual buildability. This can be done by laser cutting from paper the parts that would be CNC Cut from steel, and then 3D printing the components that we would otherwise get off-the-shelf. For the 3D printing - it is critical that we print every single part - up to bolts and nuts - so the entire assembly we can verify every single step of the build.&lt;br /&gt;
&lt;br /&gt;
This leads to the second use of collaborative prototyping - producing build instructional manuals and videos using the scale models. This allows contributors all over the world to produce meaningful content - without requiring that the contributors have access to a workshop. Since qulaity intstructionals production requires as much effort as the design work - this is another way to contribute to a large, parallel development effort.&lt;br /&gt;
&lt;br /&gt;
The third route to collaborative prototyping is the production of Model Kits for actual products. For example, the Seed Eco-Home lends itself very well for such modeling. Another company, Arckit (ref), is a good model for how we can design the model kit for the OSE’s collaboration with the Open Building Institute.&lt;br /&gt;
&lt;br /&gt;
Fig. Arckit is a great example for modeling. In the OBI case, the models correspond to real building panels and real build procedures. This makes the OBI Architecture Kit a tangible way for people to get involved in meaningful design of future house models.&lt;br /&gt;
&lt;br /&gt;
The OBI Architecture Kit lends itself well to 3D printing as well as laser cutting. 3D printed parts would snap together like Lego blocks.&lt;br /&gt;
&lt;br /&gt;
Another model kit that would be very useful to GVCS prototyping is the Machine Build Kit -  a kit for producing tractors, heavy equipment, and other automated machines. Combined with the OBI Arch Kit for buildings - this would produce the Civiliation Model Kit. The concept for the Machine Build Bit is a mixture of Lego Mindstorms, MakeBlock, Erector Set, Capsela, Box Beam Sourcebook, and Solar Micro Power Cube (all refs) - so that the system can run on solar power. The value proposition is that the kit would once again be based on real buildable parts - thus extending its use from childsplay to real design work.&lt;br /&gt;
&lt;br /&gt;
The OSE Developer Kit + Model Kits pave the way for the 4th route to collaborative prototyping - that of developing open source enterprise. These 2 kits are products in themselves - and can be used as the basis for collaborative business development of distributive enterprise (ref). The concept here revolves around reaching the $1T tipping point for the open source economy - the point at which mainstream adoption of open source economics is likely ($1T is calculated as the 10% tipping point at which viral adoption of open source economics can occur. This coincides with the next Enlightenment of humanity - see Tipping Point on the wiki - http://opensourceecology.org/wiki/The_Tipping_Point  ). This is as large as the combined revenue of Apple ($229B), Google ($79B), FB ($41B), Amazon ($178B), and Walmart ($486B) combined (Microsoft ($90B) - not includes so total is $1T.) - the latter being the single largest corporation in the world.&lt;br /&gt;
&lt;br /&gt;
OSE’s distributive enterprise approach to the tipping point is distributive. The core of OSE’s economic theory is that, by definition, a distributive enterprise serves its customers more effectively than any proprietary enterprise. Thus, a DE has a high likelihood of deposing the corporation http://opensourceecology.org/wiki/The_Corporation  as the dominant societal institution, replacing it with the next phase of the human economy - the open source economy. The transition is in our view likely - because the goal of a distributive enterprise is to produce free enterprise - defined as  distributing wealth most equitably. Current economic paradigms do not internalize distribution in their economic models. The next economy is achievable via full cost accounting and zero competitive waste, thereby achieving zero marginal cost (ref ZMCS). This proposition is simple to grasp, but most challenging to execute. We are not interested in DE as an ideology - but as a pragmatic proposition that simply meets needs more effectively - in an integrated sense -  than current models.&lt;br /&gt;
&lt;br /&gt;
The ask for distributive enterprise is to create the Open Source Everything Store - a networked and collaborative store based on Open Source Microfactories. That is - for people to collaborate on open source product development as a massive parallel effort. Decentralized, distributed, networked production is not a new idea - many people love and claim the idea as their own. To date no successful, economically-viable implementation exists, and certainly not open source. There were many attempts, from the FabLab, Local Motors, 1000 Garages, Ponoko - but none are both distributed and open source. The FabLab is a distributed microfactory concept, but none of its machines are currently open source. FabLabs are are externally funded, and none are used to run a successful business. Local Motors works on distributed production, but their designs and microfactory tools are not open source. 1000 Garages appears stalled. Ponoko and many operations like Ponoko are available. They are successful enterprises, but they do not use open source production tools or software. None of these projects provide open source enterprise information. Perhaps the best examples are 2: first, Lulzbot, which shares its machine designs and enterprise blueprints (blog post from 2014 visit, google Distributive Enterprise) - which makes it a fully open source hardware company - but it has a centralized business model. Second, there is the poster child RepRap project - which is the design/collaboration repository for open source 3D printers. RepRap is responsible for producing most of the consumer 3D printing industry’s companies - both open source and proprietary. (ref) However, RepRap in itself does not have a revenue model. Our own work is also based on the RepRap - it’s the basis that saved us hundreds of development hours - as we could simply build upon their designs. We do have a successfully-demonstrated revenue model of ongoing Extreme Manufacturing workshops.&lt;br /&gt;
&lt;br /&gt;
For The Open Source Everything Store (TOSES), any product developed must include open source blueprints, as well as open source enterprise documentation. Assets such as marketing materials, revenue models, business plans, projections, and entrepreneurship training - among others - must be included to facilitate startup by others. For successful startup - the enterprises themselves must be tested and proven. Thus, case studies of projections, actual revenue, and growth must be included. &lt;br /&gt;
&lt;br /&gt;
With as small an infrastructure as a Personal Microfactory with 3D printing, the CNC circuit mill, laser cutter, filament extruder, and off-shelf components - production of many valuable products can be distributed far and wide. Moreover, open design allows for extended product lifetime - as parts can be upgraded, modifications can be 3D printed, and breakages fixed with readily-accessible parts.  The success of TOSES  revolves around a massive parallel open source product development process - resulting in best-in-class products. These products are then produced by distributed players. Thus, a networked effort could reach substantial distributed production - and distributed sales volumes on the scale of Amazon. &lt;br /&gt;
&lt;br /&gt;
Our claim is that Distributive Enterprise has a good chance of succeeding because of its distributive nature. The cost structure of distributive development is efficient - as it relies on an open source process. We are assuming here that the zero marginal cost prediction - that everything trends to zero marginal cost - which is the competitive advantage of TOSES. However, zereo marginal cost is inherently impossible within the current system. The profit motive of the corporation prevents zero marginal cost, and leads to a permanent inefficiency in human economics. This can be resolved only by a transition away from the traditional corporate IPO form (ref). This is the reason why OSE proposes that a transition to the open source economy is inevitable. However, leading economic theorists such as George Gilder claim that human constructs are not inevitable - they have to be created. Thus, it remains up to human will to decide whether we would like to implement true-cost accounting to transition to the open source economy.&lt;br /&gt;
&lt;br /&gt;
The choice is up to us, and as such we are working on the DE model. Once open source product and enterprise blueprints are available - it means that everyone has access to them. This indicates that efficient production can be distributed into a networked form, which can gobble up Amazon and Walmart. Such a transition to the true-cost accounting economy is the promise of open source economics.&lt;br /&gt;
&lt;br /&gt;
In practice, this requires that open source microfactories, as well as open source materials production facilities - are distributed far and wide. These take abundant natural resources and convert them to a modern standard of living in a distributed way. People can produce with their personal microfactories. Using the 3D printer, circuit mill, laser cutter, and filament extruder - and off-shelf components - people can produce many household goods, electronic gadgets, toys, tools, kitchenware, small appliances, lab equipment (ref), and many others.  The size of the plastic industry alone is $2T - and the size of the injection molding industry is about $100B. Between vaccuum cleaners ($1B), consumer 3D printers ($1B),  cordless drills ($1B in the USA alone), drones, phones, cameras - the market size for those goods is on the order of hundreds of billions of dollars worldwide.  The current limit is 20% of GDP - the manufacturing sector of the economy - or about $16T.&lt;br /&gt;
&lt;br /&gt;
The centralized factory can become obsolete, and many parts of global resource flows can become localized. Specifically - as resource constraints to longer fuel resource conflicts and poverty - humans as a whole have - for the first time in world history - a chance for collective evolution. That simply means that the leading preoccupation transitions from making a living, surviving, or paying off debt - to thriving. This means that the multidisciplinary genius will become much more common - as society reaches a new level. An Einstein could be born every minute. (That makes it 1/250 - or 0.4% of the population.) This means that we transcend William Gibson’s — &#039;The future is already here – it&#039;s just not evenly distributed”. This means that most people will gain access to significant improvement in their quality of life. But this is also not a state of coerced equality as in communism - there will always be outliers who are more ambitious or skilled. But all have a good oportunity to thrive. &lt;br /&gt;
&lt;br /&gt;
CNC Torch and Larger Machines: Heavy Duty CNC Machining&lt;br /&gt;
&lt;br /&gt;
==CNC Torch Table==&lt;br /&gt;
&lt;br /&gt;
The universal axis can handle much larger forces - up to one thousand pounds - when it is scaled up. The universal axis has aleady been used with the 3D Printer and the CNC circuit mill. http://opensourceecology.org/wiki/Universal_CNC_Axis   &lt;br /&gt;
&lt;br /&gt;
We have already built a prototype of the CNC torch table using the Universal Axis, scaled up to a 2x3 meter working area:&lt;br /&gt;
&lt;br /&gt;
Fig: CNC Torch Table build workshop results. (https://www.facebook.com/marcin.jakubowski.378/posts/10213076897374250) &lt;br /&gt;
&lt;br /&gt;
The CNC Torch Table is near release status, and it will be the critical machine used in digital fabrication. The CNC Torch table will be used to cut all metal from flat sheets, which are then welded into 3D machines such as the brick press and tractor. The CNC Torch Table will also be used for cutting holes in 4” square tubing - which is our characteristic life-size erector set design.&lt;br /&gt;
&lt;br /&gt;
Typically, acetylene is used as a cutting gas. In the OSE case, the CNC torch table integrates with the oxyhydrogen production - where water is split into hydrogen and oxygen using electrolysis. These hydrogen and oxygen gases are used as the cutting gases. Oxyhydrogen cutting has been in use prior to the discovery of oxyacetylene cutting in 1903 https://en.wikipedia.org/wiki/Oxy-fuel_welding_and_cutting  - and was preferred for 2x the cutting speed with thick metal. Currently, oxyhydrogen is use whenever a clean cut is required. Otherwise, the gas is 2x as expensive as acetylene. The advantages of hydrogen are the ability to cut aluminum and stainless steel, which acetylene cannot do. Furthermore, if the open source oxyhydrogen generator is used with PV electricity at 1.5 cents per kWhr, then the cost of the gas should go down to about 5x lower than acetylene. Given these advantages, it is interesting to see that oxyhydrogen cutting is not used more commonly in the workshop. The apparent reason for this appears to be the lower price of fossil-fuel derived acetylene. Off-shelf on-demand oxyhydrogen generators appear to be expensive, so they would benefit greatly from being open-sourced. https://www.alibaba.com/product-detail/Gas-generation-equipment-for-oxgen-hydrogen_1950398042.html?spm=a2700.7724838.2017115.380.1b0840b43VI2AU  Hydrogen generators which can produce enough gas for cutting ½” steel are  are available for around $300, not including power supply. http://opensourceecology.org/wiki/Oxyhydrogen_Generator_Cost &lt;br /&gt;
&lt;br /&gt;
The OSE CNC torch table system includes a water bed to minimize smoke and prevent steel from warping while cutting, automatic height control which follows the surface of the metal for optimal cutting, an automatic ignitor, automatic gas control, open source controller, and open source controller software. Each of these piecces has been tested separately, and now we are putting the entire system together to a product that from 2018 onwards will be used to cut all steel for OSE in house. We cut steel for frames of the 3D printer, metal for the brick press, tractor, and just about every other GVCS tool.&lt;br /&gt;
&lt;br /&gt;
==Heavy Duty CNC Multimachine==&lt;br /&gt;
&lt;br /&gt;
The CNC Multimachine is a mill, drill, lathe and other tools in one machine, designed for modularity and flexibility, including rotary indexing and a grinding attachments. It can be used to produce engines and hydraulic motors, threaded parts such as bolts and pipe threads, as well as myriad other parts. The lathe has historically been the cornerstone of precision machining, and is a critical tool in civilization.  It is also another application of the OSE Universal Axis system - using the 2” rod size.&lt;br /&gt;
&lt;br /&gt;
Two other GVCS machines - the induction furnace which melts scrap metal to make virgin steel -  and the Mill which makes Rods and Wire - provide feedstocks for the CNC Multimachine.&lt;br /&gt;
&lt;br /&gt;
Fig. The 2” Universal axis can produce parts with accuracy of 10 microns, based on the deflection of 2” rods with 200 lb of force. This image shows the size comparison between the 2” version - and the 1” and 5/16” versions. The belt drive system can be identical to the smaller machines.&lt;br /&gt;
&lt;br /&gt;
We are interested in developing a core set of modules for a heavy duty machine - including mill, drill and lathe, with rotary and angle tables, plus capacity to function as a screw machine for making threads and bolts. We also include internal threads splines. &lt;br /&gt;
&lt;br /&gt;
Just like with the OBI Arch Kit (make sure reference is correct to rapid prototyping above), the Multimachine Construction Set will allow for modeling with 3D printed parts, which will correspond directly to real life - and thus serve as an educational kit and product. Together with the Multimachine Design Guide and FreeCAD workbench, people will be enabled to build their own multimachines and screw machines.&lt;br /&gt;
&lt;br /&gt;
For the 2” universal axis system, the practical limit is 400 lb of tool force with 0.001 precision and GT2 belt drive. For higher tooling forces, we must use lead screws instead of belts.&lt;br /&gt;
&lt;br /&gt;
The goal of the CNC multimachine is to produce electric motors, hydraulic motors, engines, cylinders, and valve blocks, among others. With a grinder attachment, the idea is to be able to achieve high precision, down to 0.0005, which is the positioning accuracy of the stepper motors at 16 microstepping and 1” GT2 pulleys.&lt;br /&gt;
&lt;br /&gt;
Using the Universal Axis, CNC linear motion control, and CNC rotary chuck control - we can get a wide array of functionality of a screw machine for making various precision parts. With a surface grinder, we can get precision parts down to 25 microns of tolerance. If we build a precision CNC surface grinder, then we can achieve up to 1 micron accuracy for making air bearings.https://www.youtube.com/watch?v=sFrVdoOhu1Q  Air bearings open the possibility of lubrication-free engines and high pressure pumps for storing hydrogen and a prerequisite for certain clean-room semiconductor manufacturing.&lt;br /&gt;
&lt;br /&gt;
==Robotic Arm - trainable for welding + 3D printing==&lt;br /&gt;
&lt;br /&gt;
The robotic arm is a powerful manufacturing tool as it is can move almost as flexibly as a human arm - but with increased precision and strength. Practical tasks that a robotic arm can accomplish depend on the end effector or tool that the arm is holding. For the GVCS, two good applications include automated welding and 3D metal printing using a MIG or TIG welder.&lt;br /&gt;
&lt;br /&gt;
Fig. Robotic welding - [nice pic] is useful for high quality welding to assist the open source renaissance woman. Spot welding or wire welding can be used.&lt;br /&gt;
&lt;br /&gt;
A useful application of robotic arms emerges from trainable robotic arms. Trainable robotic arms are arms which a human operator can train to move as needed. This eliminates complex programming tasks, making robotic collaborators accessible to the general public. An open source software platform already exists for robotic arms in the Robotic Operating System (ROS) project, including trainability.http://moveit.ros.org/  - such that the open source trainable industrial robot is around the corner by building on existing prior art. &lt;br /&gt;
&lt;br /&gt;
==Induction Furnace==&lt;br /&gt;
&lt;br /&gt;
An induction furnace is a device use to melt metal.  Metal can then be recycled - from scrap to useful stock. The advantage of the induction furnace over any other means of melting metal is a clean, energy-efficient and well-controllable melting process. In a typical induction furnace, a water-cooled copper coil with alternating current induces a current in a crucible of metal - hence the name Induction furnace - and that current heats up and melts the metal. Due to the heat being generated within the work piece, energy transfer is extremely efficient.&lt;br /&gt;
&lt;br /&gt;
Fig. In an induction furnace&lt;br /&gt;
&lt;br /&gt;
The induction furnace brings us from the stone and wood age - when stone and wood were the most common materials for making houses and machines - into the iron age - which is synonymous with the industrial age and modern civilization.  &lt;br /&gt;
&lt;br /&gt;
It may be said that modern civilization has culminated with the production of ball bearings. Bearings are a critical component that allows for engines, turbines of modern power to work - and precision machines that use precision ball bearings are used to manufacture these machine. Finally,  vacuum pumps and precision instruments - necessary in semiconductor manufacturing - depend on the use of bearings. As such, the information age today also relies on ball bearings - a combination of material science and precision manufacturing.&lt;br /&gt;
&lt;br /&gt;
==Metal Rolling, Rod &amp;amp; Wire Mill==&lt;br /&gt;
The induction furnace can be used in metal casting, where round rods or billets are cast and then used as feedstocks for metal rolling.&lt;br /&gt;
&lt;br /&gt;
Metal rolling uses rolling dies to shape metal into various profiles, from flat, to round, to angled. &lt;br /&gt;
&lt;br /&gt;
Fig. Metal rolling uses dies of various shapes to produce final stell shapes.&lt;br /&gt;
&lt;br /&gt;
Rolling of thin rounds - or rods - around dies and pulleys - is used to elongate and thin the rounds results in wire - a fundamental building block of civilization. Wire is used for house electrical wiring, suspension,  or fencing.&lt;br /&gt;
&lt;br /&gt;
Fig. A wire drawing machine starts from rod and stretches it to wire through a number of dies. The modular open source version can take rod and turn it into wire of any diameter.&lt;br /&gt;
&lt;br /&gt;
Metal rolling that occurs above the crystallization temperature (700C) is called hot rolling - and it takes less energy to do so as the metal is pliable. Cold rolling occurs at room temperature, and therefore requires more energy to deform the metal - but it also provides more accurate dimensions in the metal.&lt;br /&gt;
 &lt;br /&gt;
==Forging, Ironworker==&lt;br /&gt;
&lt;br /&gt;
The press forge is a heavy duty press than can be used to squeeze metal like butter. When metal is hot, it can be deformed into useful shapes by using a die. Bolt heads are made this way.&lt;br /&gt;
&lt;br /&gt;
Forges can take the form of press, drop, or roll rolling - preferably using the induction furnace for efficient forging. Cold forging may also be done, but that requires larger force for a given deformation.&lt;br /&gt;
&lt;br /&gt;
Forging is useful but the disadvantage is using specialized forming shapes or dies. Thus, the preferable route to forging would in many cases be subtractive machining, metal 3D printing,  or welding - as these are general-purpose procedures that do not require custom forms or dies.&lt;br /&gt;
&lt;br /&gt;
Fig. The press forge can shape hot or cold metal like butter.&lt;br /&gt;
&lt;br /&gt;
==Plasma Cutter, Welder==&lt;br /&gt;
&lt;br /&gt;
The plasma cutter, welder, and induction furnace are high-power electronics that use modern technology for efficiency. By using transistors and inverter circuits instead of large transformers, they can be light-weight and low cost - as the cost of power transistors is 10 cents/kW of power handling ability. This means that the simplest welder circuits can cost only a few dollars in electronic components (not counting wiring, structure, and the balance of system) to get industrial welders on the scale of 10kW (500Amps).&lt;br /&gt;
&lt;br /&gt;
Fig. Diagram of a welder. From first principles, a welder includes power handling electronics, wires, a case, cooling fan, and a welding gun with an electrode, and shielding gas for high quality welds.  In the simplest case - a tungsten electrode creates an arc to the metal and melts the metal, without using filler. This is an example of autogenous welding, where no welding rod or wire is required.  Welding is not complicated - the simplest electric arc welder is a 12V battery connected to a welding rod.&lt;br /&gt;
&lt;br /&gt;
A plasma cutter is a transistor-based power electronic device that cuts conductive metals with a plasma - or ionized gas.  The plasma cutter creates ionized air between an electrode and a work piece. The plasma heats the metal. By directing a focused stream of air around that plasma through a nozzle, the heated metal is oxidized and blown away, creating a clean cut. For comparison,  cut quality  in order of improvement is plasma cutting, oxy-fuel, waterjet, and laser cutting.&lt;br /&gt;
&lt;br /&gt;
Fig. Cut width - or kerf - of plasma, oxyfuel, waterjet, and laser cutting.&lt;br /&gt;
&lt;br /&gt;
Both the plasma cutter and welder are similar to each other. They have similar power electronic circuits.  For a welder or plasma cutter, the main difference is in the gun and electrodes. The gun in both cases has a large copper power wire and a gas line for shielding. For the MIG welder, it also has wire feed. The electrode is tungsten for the TIG welder and plasma cutter, and consumable welding wire for the MIG.&lt;br /&gt;
&lt;br /&gt;
More Power Electronics&lt;br /&gt;
&lt;br /&gt;
Is EDM practical? EDM is a high-voltage spark erosion system for cutting thick metals - where a moving wire at 10,000VDC spark-erodes metals as tiny sparks are established between the wire and metal to be cut. This system is insulated&lt;br /&gt;

&lt;div&gt;Walking through the 50 Technologies and Their Economic Impact&lt;br /&gt;
&lt;br /&gt;
Disclaimer - Graph of completion&lt;br /&gt;
Here we discuss all the tools, but please remember that in Part 1 of the 4 Part Series, many of the machines are still on the drawing board.&lt;br /&gt;
&lt;br /&gt;
=Agriculture=&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
If you eat, you use a Tractor. Maybe not you directly, but the farmer that grew your food. And food is a $8T industry. The GVCS field agriculture machinery that support this $8T industry &amp;lt;ref&amp;gt;https://www.plunkettresearch.com/statistics/Industry-Statistics-Global-Food-Industry-Statistics-and-Market-Size-Overview/&amp;lt;/ref&amp;gt; are:&lt;br /&gt;
&lt;br /&gt;
Fig 1. The Tractor, Microtractor, Microcombine, Universal Seeder, Spader, Hay Cutter, Hay Rake, Baler, and Dairy Milker, and a Bakery Oven are critical tools of the $8T food industry.&lt;br /&gt;
&lt;br /&gt;
==Tractor, MicroTractor, Bulldozer and Power Cubes==&lt;br /&gt;
&lt;br /&gt;
The tractor is a cornerstone of a farm, construction, or other materials production industries. A tractor has the traction to pull things, and to do utility work with variou implements that can be added to a tractor and use the tractor’s mechanical power through a Power Take-off (PTO). As such, the tractor can be a swiss army knife of heavy duty work. For the smaller individual or home scale, we have the MicroTractor in the set, which is a small, walk-behind or ride-on tractor at the 16-32 hp size that can perform many gardening and utility functions and can fit in a smaller areas where a large tractor would be impractical. If we go up in scale - use a stronger frame and at least 64 hp, and add a bulldozer blade to the tractor - then we have a bulldozer.&lt;br /&gt;
&lt;br /&gt;
The tractor is a machine on the scale of 50-320 hp in the GVCS ecosystem, and unlike traditional tractors, we focus on modular power. We currently use small 16 hp engine units at $17/hp (ref), which is the lowest cost way to obtain engine power, while making maintenance very easy. Like in nature where a tree is made of many branches, our tractor is made of many small engine units. This way, the same design pattern can be used in the 16 hp tractor as in the 320 hp tractor. The price for using larger diesel engines is 2-4 times larger.  &amp;lt;ref&amp;gt;http://opensourceecology.org/wiki/Diesel_Engine_Cost &amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
By using the modularity concept, we create our typical construction set approach for heavy machines. For example, if a large tractor frame is fitted with a bulldozer blade - then we don’t require a separate bulldozer in addition to a tractor. This saves a lot of resources - making technology significantly lower cost to maintain. Exploring the limits of modularity, we found that it is much less expensive to scale our machines usig modular and overbuilt parts that make sense both for small and large machines. For example, we can use 4 of our identical track units, each rated for up to 80 hp - Our track unit, for example, allows for a $30k version &amp;lt;ref&amp;gt; http://opensourceecology.org/wiki/Modular_Track_Unit_v18.01&amp;lt;/ref&amp;gt; that matches the traction of a Cat D7 - a sizeable cost savings comprd to a base price of ½ a million. &amp;lt;ref&amp;gt;https://www.caranddriver.com/reviews/caterpillar-d7e-feature-test &amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Fig. Pattern Language for a Tractor - up to automated control.&lt;br /&gt;
&lt;br /&gt;
The key is making it easy and quick to interchange parts - from small parts to large implements. This is a great challenge for advanced industrial design.&lt;br /&gt;
&lt;br /&gt;
Fig. Industrial smaller parallel and trained configuration. OSE machines can be designed like this, but higher flexibility of the OSE platform can allow for an improved configuration.&lt;br /&gt;
&lt;br /&gt;
Fig. The flexibility of a modular OSE tractor. The modular OSE tractor can be built from the same components, but apply to 16 hp or 320 hp machines while using the same over-engineered components such as the ½” thick steel tracks &amp;lt;ref&amp;gt;Current design is rated for  rated for 40 hp per track or 80 hp with double drive, . (ref - do calculations) and 3600 lbs or 7200 of pull each. Thus, a four-tracked machine can have 29,000 lb of pulling force with direct drive using our current 15k in-lb motors.&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
==Spader, Seeder, Bulldozer==&lt;br /&gt;
&lt;br /&gt;
Your food today is grown largely by tractor-driven  tilling and seeding, unless you’re a breatharian. Tillage in the OSE system chooses the spader as a more progressive technology compared to the age-old plow. &lt;br /&gt;
&lt;br /&gt;
Fig. (Image of 1800 steam tractor with 50 bottom plow) &lt;br /&gt;
&lt;br /&gt;
The spader works essentially like  a bunch of shovels moving rapidly - which till soil without crating a hardpan typical of the more common plow. Manufacturers claim that spading uses 40% less fuel than plowing - because a spader can combine tilling, harrowing, and planting in one operation. &amp;lt;ref&amp;gt;https://www.farmax.info/PDF/Magazine-Farmax-EN.pdf &amp;lt;/ref&amp;gt; A plow, which drags through the soil, requires a lot of wheel-to-ground  traction, whereas a spader requires very little - thus avoiding soil compaction. It takes a spader under 9 minutes and 2 gallons of fuel per acre of field - such that feeding Dunbar Village &amp;lt;ref&amp;gt;A village of 200 -  based on Dunbar’s number https://en.wikipedia.org/wiki/Dunbar%27s_number &amp;lt;/ref&amp;gt; would take 6 hours to plant for a whole year of crop &amp;lt;ref&amp;gt;Assuming field crops planted with a seeder, not slips like sweet potatoes. http://opensourceecology.org/wiki/Acres_Needed_to_Feed_Dunbar_Village &amp;lt;/ref&amp;gt;Thus, one day to plant, two days to harvest - and the village has food for the year. &lt;br /&gt;
&lt;br /&gt;
The tractor and universal seeder is an example of how we approach multiple purpose machines. The tractor is a large-size swiss army knife for doing many different tasks. The Universal seeder is designed to plant all types of seed, from alfalfa to wheat, to tubers, and to live plants like sweet potato slips. Modifying the device rapidly is key to this flexibility.&lt;br /&gt;
&lt;br /&gt;
Fig. Swiss army knife tractor concept&lt;br /&gt;
&lt;br /&gt;
The point of using powerful machines wisely is that in the OSE perspective of lifetime growth -  life could become easy so we can focus on evolving as humans. Our experiment involves building a college campus where peole live this. When they graduate, they know how to organize a village to spend 2 hours per day working on survival, and then the rest of their life they pursue their highest ideals.&lt;br /&gt;
&lt;br /&gt;
The experimental village thus requires one farmer who is employed 3 days of the year, assuming the equipment does not break down, and generates 30 acres * $20k/acre of sweet potato, and $5k/acre for 10 acres of wheat if that is turned into bread  - or $650k worth of food for the community with direct marketing. That is $27k/hour if baking is automated - a decent pay, but not like the $25k/minute rate of Warren Buffett &amp;lt;ref&amp;gt;http://www.businessinsider.com/what-warren-buffett-makes-per-hour-2013-12  &amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Of course these are unreasonable figures, but they do represent the idea. The only way that customer acquisition and marketing costs do not ruin such ideals is in the case of direct marketing - where the on-site farmer-scientist provides for a captive audience of the Dunbar village. If each person eats about $2600 per year &amp;lt;ref&amp;gt;https://www.google.com/search?q=average+cost+of+food+per+year&amp;amp;oq=average+cost+of+food+per+year&amp;amp;aqs=chrome..69i57j0l5.7243j1j7&amp;amp;client=ubuntu&amp;amp;sourceid=chrome&amp;amp;ie=UTF-8&amp;lt;/ref&amp;gt;, feeding 150 people would involve revenues of $390k - but that would be a full time job. We will look more carefully at the business model for resident farmer agriculture in the Enterprise chapter.&lt;br /&gt;
&lt;br /&gt;
Now it would take more time to do a diversified operation, but this is shown just as a baseline to see what’s possible in terms of the effort.  Several Ph.D.’s can be granted to develop a diversified, 40 acre subscription farm, using open source equipment and a captive market, or Local Food Nodes as part of a distribution platform.  &amp;lt;ref&amp;gt;https://localfoodnodes.org/&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The OSE project will develop such a food enterprise both for its campuses and for the outside community - once all the farming machines are done, the aquaponic greenhouse production is optimized, and derivative food processing tools are developed.&lt;br /&gt;
&lt;br /&gt;
The open source tractor can be built at a cost of $125/hp at a scale of 80 hp, compared to $370-$1000 for other brands. It is useful to understand the basic cost breakdown based on off-the shelf parts:&lt;br /&gt;
&lt;br /&gt;
Fig. Cost breakdown of a tractor by Frame, engine, hydraulics, control, automation, and balance of system - $125/hp. (p590MJ)&lt;br /&gt;
&lt;br /&gt;
The cost advantage is less visible at the 32 hp MicroTrac, at $160 per hp - though but a comparable mahine like the tracked Toro Ding costs around  $1000/hp (ref).&lt;br /&gt;
&lt;br /&gt;
Fig. Microtrac with tooth bar bucket can till your garden, and provide valuable utility work. It is an indidspensible utility machine for any prosumer.&lt;br /&gt;
&lt;br /&gt;
==Hay Cutter, Rake, Baler==&lt;br /&gt;
&lt;br /&gt;
If farm animals are involved, then you need these. Or if you want to move large quantities of materials, then a bale is a useful form: from a bale of hay, brush, cotton, cardboard, or plastic - bales allow large scale moving of materials. Bales of aluminum cans are likewise useful for melting down in your induction furnace. If you are making fuel pellets from biomass, plastic pellets for making 3D printer filament - you will need a baler to make 1 ton bales.&lt;br /&gt;
&lt;br /&gt;
==Dairy Milker== &lt;br /&gt;
For animal husbandry, hay baling stores hay for the winter. Unless you are talking about the fish in your home aquaponic system. Dairy products themselves are $116B &amp;lt;ref&amp;gt;https://www.ibisworld.com/industry-trends/market-research-reports/manufacturing/food/dairy-product-production.html &amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
of the global economy - hence the relevance of the dairy milker. &lt;br /&gt;
&lt;br /&gt;
Table: values of the overall food, dairy, cattle, vegetable markets worldwide.&lt;br /&gt;
Combining the dairy milker with computer vision and automation, we envision a solar robotic milker - our MicroTrac with a milking stall - that drives up to a cow to milk her, and then brings the milk back for storage and processing. This allows field milking without human labor for small diversified robofarms that combine the best of regenerative agriculture with modern tehnology to relocalize farming.&lt;br /&gt;
&lt;br /&gt;
Fig. Robotic milker&lt;br /&gt;
==MicroTrac== &lt;br /&gt;
&lt;br /&gt;
A very interesting use arises with a small, solar, robot tractor - the MicroTrac driven by a solar panel. By adding a $10 Raspberry Pi Zero Controller &amp;lt;ref&amp;gt;https://www.adafruit.com/product/3400?gclid=EAIaIQobChMI2rz0mcnd2gIVCzlpCh3MpQgIEAQYAiABEgKi7_D_BwE&amp;lt;/ref&amp;gt; and a $100 solar panel you can be your robotic tractor - for agriculture and other. You can now mow your lawn automatically, and even pelletize it for fuel for a pellet stove. This is possible because today - advanced microelectronics such as the Raspberry Pi is 100 times faster that the first supercomputer, which cost $9M &amp;lt;ref&amp;gt;https://www.theregister.co.uk/2008/01/05/tob_cray1/ &amp;lt;/ref&amp;gt; in 1975.&lt;br /&gt;
&lt;br /&gt;
Fig. A solar-driven MicroTrac concept with solar panel and $50 arduino controller can provide autonomous agriculture &lt;br /&gt;
&lt;br /&gt;
==Bulldozer==&lt;br /&gt;
&lt;br /&gt;
Now add a bulldozer blade to a beefed up, tracked tractor - and you have one of the most powerful devices for regeneration - or destruction - depending on how you use the machine. Bulldozers are powerful earth moving machines - to build roads, grade house foundations, and in agriculture - to build regenerative earthworks for water and erosion. The biggest example is the 12,000 square miles that have been regreened in China - the Loess Plateau. &amp;lt;ref&amp;gt;John Liu reported on this - http://www.aquinta.org/news/2016/10/6/greening-the-desert  &amp;lt;/ref&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Fig.&#039;&#039;&#039; Loess Plateau reforestation&lt;br /&gt;
&lt;br /&gt;
So, if you ever drove on a road - you used a bulldozer. Maybe not you, but whoever graded the road base. &lt;br /&gt;
&lt;br /&gt;
==Microcombine==&lt;br /&gt;
&lt;br /&gt;
The Microombine is used to harvest grains and seeds of any type. This is the core of human harvests world wide. For the OSE case, we have a much more flexible and modular machine in mind. Based on our module-based aproach, we can use the same drive platform as the tractor&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Fig&#039;&#039;&#039;. Showing the base drive platform that can be used &lt;br /&gt;

==Bakery Oven==&lt;br /&gt;
&lt;br /&gt;
Humble bread is a $419B global market https://www.ibisworld.com/industry-trends/global-industry-reports/manufacturing/bakery-goods-manufacturing.html . It is the 12th most popular food in the world. https://www.farmflavor.com/at-home/what-is-the-most-popular-food-in-the-world/  And 49% of Americans eat bread  https://www.smithsonianmag.com/smart-news/each-day-50-percent-america-eats-sandwich-180952972/ . &lt;br /&gt;
&lt;br /&gt;
Now bulldozers, tractors, and combines are all good - but the next step for gobal agriculture is the transition to  perennial polyculture  https://www.youtube.com/watch?v=KpJR2yfLUU0  , with only a small fraction of tillage ramaining.&lt;br /&gt;
&lt;br /&gt;
=Construction - 13 Tools=&lt;br /&gt;
If you want to build a charter city or a smaller campus, you will need construction equipment - and a trencher to put in gigabit internet fiber between the locations.&lt;br /&gt;
&lt;br /&gt;
The tools in the construction part outside of the tractors include the backhoe, trencher, cement mixer, sawmill, CEB press, well-drilling rig, soil pulverizer, hammermill. The universal rotor is a tool used in other sectors of the GVCS - and the SeedHouse is a living machine. &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Fig. 13 tools of the construction part of the Global Village Construction Set.&lt;br /&gt;
&lt;br /&gt;
==Backhoe, Trencher, Cement Mixer==&lt;br /&gt;
&lt;br /&gt;
The backhoe or excavator can be used to dig aquaponic ponds, foundation trenches. It can be used to remove stumps, do trenching, and with a grapple it can be used to lift logs or to hoist heavy objects. Backhoes are relatively simple devices - a set of pivot joints that use hydraulic cylinders for their motion - producing thousands of pounds of digging force at the touch of control levers. There are both side-to-side moving backhoes, but a 360 degree rotating backhoe is much more flexible. The small side to side version can be used on a front quick attach of a tractor.&lt;br /&gt;
&lt;br /&gt;
Fig. OSE backhoe from 2010 https://www.google.com/search?q=ose+backhoe&amp;amp;client=ubuntu&amp;amp;hs=ToH&amp;amp;source=lnms&amp;amp;tbm=isch&amp;amp;sa=X&amp;amp;ved=0ahUKEwjLzZKelOLYAhULbawKHQo-DVwQ_AUICigB&amp;amp;biw=1351&amp;amp;bih=731#imgrc=t8j52U9--mn6BM:  mounted on he original lifetrac, a small one used for water line trenching in 2012 http://opensourceecology.org/wiki/File:Bhp1.jpg , and a larger one from 2013 https://www.youtube.com/playlist?list=PL6Jpysxw3Ty-oH4bggp32PR_rPWr8bKC1 . Next iteration is the 360 degree backhoe with remote control drive to facilitate hydraulic line routing.&lt;br /&gt;
&lt;br /&gt;
The trencher in the original GVCS icon is a wheel trencher. We built 2 prototypes, and the next iteration will be a chain-based trencher based on our favorable experience with oversized chain drive on the bulldozer tracks.&lt;br /&gt;
&lt;br /&gt;
Fig. OSE Trencher http://opensourceecology.org/wiki/Trencher - 2011 and 2013 builds.&lt;br /&gt;
The cement mixer is indispensable. Cement has been used in ancient Rome and in mesoamerican temples. Scotland&#039;s County Cork had 23,000 lime kilns at one time - had one kiln per 80 acres. Wood or coal was used as fuel. http://www.lowtechmagazine.com/2013/09/lime-kilns.html  http://www.chapelgatehome.uk/our-blog   Portland cement took over lime cement in the last 100 years, but lime concrete is favorable in foundations becaue it doesn’t crack as easily as Portland. Using modern appropriate technology, lime cement production in solar microfactories is a viable enterprise at the 1 ton per day scale using an open source microkiln the size of a refrigerator. Limestone goes in one end, and lime comes out the other. With such small appliances costing around $1k, cement production can be distributed - while making cement production carbon neutral, annihilating  the current 5% CO2 emission share of the the concrete industry.https://en.wikipedia.org/wiki/Environmental_impact_of_concrete  This is possible in about 50% of America, where the bedrock is made of limestone. That’s a $10B industry in the USA alone.https://en.wikipedia.org/wiki/Cement_industry_in_the_United_States &lt;br /&gt;
&lt;br /&gt;
The cement fryer - a rotary lime kiln - is much like the cement mixer: a Universal Rotor with a heating element. A rotating pipe heated by PV, and an Arduino microcontroller to measure temperatures and guide the process to efficient completion. While not part of the 50 GVCS technologies, it’s a ready derivative:&lt;br /&gt;
&lt;br /&gt;
Fig. PV of the Open Source Materials Production Facility, a solar Power Cube, a Universal Rotor, metal pipe and an Arduino microcontroller constitute the lime cement maker.&lt;br /&gt;
&lt;br /&gt;
If we want to go to the essence of construction, take the backhoe excavator, chase it with a bulldozer with ripper shanks, and then rock under a site could be extracted to build a pond. This rock, if limestone, is feedstock for your lime kiln. In some places, rock outcroppings make access to limestone easy.&lt;br /&gt;
&lt;br /&gt;
==CEB Press , Soil Pulverizer, and Sawmill==&lt;br /&gt;
&lt;br /&gt;
The Compressed Earth Brick press and sawmill are critical tools for construction in that they produce materials. The CEB Press allows one operator to load raw dirt right from the building site to produce about 5000 bricks in a day - enough for a small house. &lt;br /&gt;
&lt;br /&gt;
Fig. The CEB Press is the first machine that we have prototyped, and it is ready for widespread replication around the world.&lt;br /&gt;
&lt;br /&gt;
We have used the soil pulverizer to prepare soil for pressing CEB blocks. The soil pulverizer was used to both pulverize the soil, and its bucket was used to press bricks for CEB construction.&lt;br /&gt;
&lt;br /&gt;
Fig. Soil pulverizer - Aidan on the tractor + loading the brick press by Yoonseo&lt;br /&gt;
&lt;br /&gt;
Our next step on the CEB press is a full soil conditioner which pulverizes soil, adds cement at a measured quantity of 5%, and then loads the mixture into the CEB press - to allow for production of high quality, stabilized block.&lt;br /&gt;
&lt;br /&gt;
Fig. The soil conditioner accepts raw soil from a tractor loader, mixes a measured amount of cement, and loads the prepared mixture into the CEB press for effective production of stabilized block at 12 cents ( 10 cent cement cost for a 20 lb block, and 2 cents gasoline cost). per block in materials. This means that we can build a 1’ thick CEB wall section for $50 in materials.&lt;br /&gt;
&lt;br /&gt;
The sawmill is a machine that can produce dimensional lumber - a staple of construction. Our sawmill is a variety known as a swing-blade sawmill, which has a single blade that can rotate 90 degrees and make a dimensional piece of lumber by going forward and back on a piece of wood.  We chose the dimensional sawmill for its simplicity over a bandsaw mill, as blade sharpening is much easier - and maintenance is the larger cost of any equipment if that equipment is designed for a lifetime.&lt;br /&gt;
&lt;br /&gt;
The sawmill is a good example of how we can use GVCS product ecologies to reduce complexity and reduce the cost of equipment. We design not just individual machines, but machine ecosystems that feed off one another. We can obtain drastic cost reduction by borrowing existing modules from the GVCS. For our case, it makes sense to design the sawmill as a Bobcat standard quick attach implement. We borrow the tractor as a  quick attach point, so that we do not need a bed upon which the sawmill head would otherwise ride. We borrow 32 hp from the tractor Power Cubes. We also  borrow the hydraulic motor which we attach with hydraulic quick-connect hoses. Thus, we have essentially stripped down the entire sawmill to the long carriage with the cutting head - saving $2k https://www.ebay.com/itm/30hp-Kohler-Engine-1-1-8-D-Command-15Amp-Exmark-CH750-0026/132423001888?epid=26011371639&amp;amp;hash=item1ed506a720:g:4YUAAOSwH2VaS3-h  on the engine, $2k https://sleequipment.com/dovetail-utility-trailer-7x20-with-3500lb-axles.html?fee=8&amp;amp;fep=524834&amp;amp;gclid=EAIaIQobChMIws349azn2AIVBqxpCh1rMwbpEAQYASABEgIeHPD_BwE  on a trailer. The greatest advantage would be the setup time - if designed as a quick attach implement, the sawmill can be taken to a log, rested right by the log, and ready for action - as compared to systems where the carriage base must be set up or the log moved into cutting position. If the sawmill can straddle right over a log or be raised with the loader arms, there is no limit ot the side of log that the mill can handle. &lt;br /&gt;
&lt;br /&gt;
Fig. The simplicity of the OSE swing-blade sawmill involves a long linear track mounted as an implement for the tractor. To provide 3 axes of motion - the loader mounting includes height adjustment (z motion), and a lightweight cantilevered head provides side-to-side motion. The cost of about $1500 is significantly lower than the $15k http://www.dltimbertech.com/dl-180-swing-blade-sawmill-10-x-20.html   minimum for a comparable 32 hp sawmill. (ref)&lt;br /&gt;
&lt;br /&gt;
And the sawdust that we generate can be used as animal bedding, insulation, or it can be pelletized to make fuel pellets.&lt;br /&gt;
&lt;br /&gt;
==Universal Rotor==&lt;br /&gt;
&lt;br /&gt;
The Universal Rotor is a fundamental building block for just about any moving machine. It is a combination of rotary motion and a useful tool-head. As a design pattern consisting of a shaft, bearings, and a motor -  a wide array of working tools can be attached to it - so that the Universal Rotor can constitute a drill, a wind turbine,  a wheel, a hammermill, cement mixer, sawmill - etc  - essentially any machine at any size - from small cordless electric drills to a larger 50kW rotor of a wind turbine. &lt;br /&gt;
The Pelletizer , Chipper/Hammermill, Dimensional Sawmill, Rototiler/Soil Pulverizer, Cement Mixer, Well-Drilling Rig, 50 kW Wind Turbine, Microcombine Thresher, and Bioplastic Extruder are direct applications of the universal rotor, and combined with precision machining structures, the Universal Rotor also include the heavy duty CNC Multimhttps://www.opensourceecology.org/portfolio/pelletizer/achine with lathe, drill press, slow cutoff saw, surface grinder, and other machines of fabrication.&lt;br /&gt;
If we can build a Universal Rotor, a Power Cube, and weld together  a supporting structure - then we have - broadly speaking - build 23 of the 50 machines of the GVCS. For example, if we consider the electric motor - it is a a shaft, 2 bearings, a structure, and the ‘tool head’ could be considered the electrical windings that make the shaft spin. Or, if we consider the metal lathe - a part of the Multimachine - then it is clear that the lathe consistr faksdjdfjks of a heavy shaft, 2 heavy bearings, and the tool-head is a chuck for holding work-pieces.&lt;br /&gt;
&lt;br /&gt;
==12. Well-Drilling Rig and Chipper/Hammermill==&lt;br /&gt;
The well-drilling rig is a machine used to dig deep water wells. It consists of a universal rotor which uses 3” (https://www.aquascience.net/grundfos-10sq05-160-230v-10gpm-1-2hp-230v-2-wire-96160140-3-stainless-steel-submersible-well-pump?gclid=EAIaIQobChMIlt-S3PDn2AIVC6tpCh369g34EAQYASABEgJr__D_BwE. 10’ of this pipe store 4 or 6.5 gallons of water. ) or 4” drill pipe to drill down to a depth of 100m or more using hydraulic rotary drilling. In this method, a stream of water is sent down the pipe during the drilling operation to send up tailings and soften the area of the drill point. A heavy duty hydraulic motor spins the drill rod - and new sections of drill rod are attached one after another. When the operation is done, the drill pipe is left underground and a submersible pump is inserted to pump water from the well.&lt;br /&gt;
Fig. A hydraulic deep well pump drilling system explained. The water swivel is the key part here. Otherwise 3” pipe that an be used as  drill pipe and casign is $12/foot. https://www.discountsteel.com/items/Galvanized_Steel_Pipe.cfm?item_id=172&amp;amp;size_no=11#skus  &lt;br /&gt;
The chipper/hammermill is another application of a universal heavy rotor with swinging or fixed blades. This machine shreds or pulverizes materials, and can be as small or large as needed.&lt;br /&gt;
Fig. Hammermill variations with various blades to chip wood or crush rock. A modified version of a heavy rotor can be a grinder. The scale can be from the largest - shredding cars - to the smallest - with small electric motors - if you have hydraulic drive and electric drive.&lt;br /&gt;
&lt;br /&gt;
==The House - Seed Eco-Home and Aquaponic Greenhouse==&lt;br /&gt;
&lt;br /&gt;
The Seed Eco-Home is a living machine - and becase it is the single largest cost of living today, we dediced to include that in the GVCS. (Initially, the house was not in the GVCS - but it was added as the Microhouse.) The  The Seed Eco-Home is the culmination of all the construction machines put to use. Homes are  also about  $3T (https://en.wikipedia.org/wiki/Construction#Industry_characteristics - residential construction is about ⅓ of all construction) market worldwide - which if open-sourced, could provide 30 million regenerative housing jobs for open source home building entrepreneurs Earning $100k each per year. This is 30 million potential collaborators - through we need only about 1000 at this time.&lt;br /&gt;
&lt;br /&gt;
The OSE/OBI https://www.openbuildinginstitute.org/  Seed Eco-Home is a an affordable, expandable eco-home that can be built for ⅓ the cost of a typical home, while including ecological features. Rather than building a large house, we propose starting with a seed home, and then growing it as the need arises. &lt;br /&gt;
&lt;br /&gt;
We are pushing ecological limits in our autonomous house design. The house is  off-grid with PV, provides its own cooking fuel from a biodigester, includes roof-top rainwater collection, and grows its own food with an aquaponic greenhouse. Mowed lawn or biomass is used to provide heating biomass pellets for a hydronic stove that is fueled by pellets. The eventual product vision is a house that  produces fuel for cars as compressed biogas or compressed hydrogen - by splitting water. Thus, we are correcting the oil and gas industry with 100% renewable energy, using simple, proven technologies. We are not relying on advancements in battery technology as a prerequisite to sustainable transportation, and by not requiring scarce lithium for batteries, we are aiming for an abundant and environmentally friendly energy future. http://www.kitco.com/ind/Albrecht/2014-12-16-How-Green-is-Lithium.html  We favor rooftop PV plus electrolysis as the preferred route for transportation fuels, where every house becomes a gas station. Using medium pressure electrolyzers that can produce hydrogen up to 33 atmospheres without needing a compressor - we can readily store hydrogen in large propane tanks or higher pressure steel pipe. &lt;br /&gt;
&lt;br /&gt;
Fig. Seed Eco-Home&lt;br /&gt;
&lt;br /&gt;
Fig. Aquaponic greenhouse glamour shot.&lt;br /&gt;
&lt;br /&gt;
The aquaponic greenhouse is designed to provide a year-round supply of fresh eggs, vegetables, fish, and mushrooms. The goal is to include automated planting with a small Farmbot (https://farm.bot/ . By Shuttleworth Fellow friend Rory Aaronson.), where the resulting deep pots are planted in the  towers. With a 1000 plant growing capacity in the main towers, the greenhouse can provide a robust salad daily, where we plant and harvest 15 plants per day from a small 800 sf greenhouse. A mushroom yield of 1lb is obtained per week from a tower that takes only 1 square foot. We also intend to use automated 3D printed aerial drones for planting seeds directly into towers - a great example of useful product ecology. Local food addresses the issue of food miles, where food travels an average of 1500 miles in the USA before ending up on someone’s plate. https://cuesa.org/learn/how-far-does-your-food-travel-get-your-plate  This is one of the numerous inefficiencies that will be addressed by a more efficient, open source economy. This brings us to transportation.&lt;br /&gt;
&lt;br /&gt;
=Transportation. =&lt;br /&gt;
&lt;br /&gt;
The microcar, truck, electric motor, and hydraulic motor are the 4 GVCS machines directly related to transportation. &lt;br /&gt;
&lt;br /&gt;
The worldwide production of cars is a total of 95M per year, 75% of which is done by the top 15 companies. https://en.wikipedia.org/wiki/Automotive_industry#World_motor_vehicle_production  This lends itself to massive distribution of power. The OSE paradigm proposes instead that there would be on the order of million distributed enterprises - essentially one per 10,000 people. Each facility would produce cars on the scale of dozens or hundreds in the community-supported manufacturing (CSM) scenario. Thus, car producers replace car dealership  - as the producer takes to dealing.  This would go well with a gas station at every home, splitting Seed Eo-Home rooftop water for fuel at a cost of 80 cent per gallon of gasoline equivalent. http://opensourceecology.org/wiki/Hydrogen_Production &lt;br /&gt;
&lt;br /&gt;
Fig. Seed Eco-Home to car fuel infrastructure consists of rooftop water collection, 10kW of PV panels, a storage tank for hydrogen, and compression to 200 bar. Piece of cake if you consider not doing this - wars for oil. This gives us about 100 miles of fuel worth per day in a 100mpg microcar.&lt;br /&gt;
&lt;br /&gt;
==OSE Microcar==&lt;br /&gt;
&lt;br /&gt;
The OSE Microar is a Hydrogen Hybrid Hydraulic (H3) vehicle. Hydrogen is chosen because an internal combustion (ICE) engine running on hydrogen is twice as efficient (40%) as a normal ICE (20%), and only 25% under the 50% efficiency of fuel cells. http://environment.yale.edu/gillingham/hydrogenICE.pdf A hydraulic drive train (71% efficiency) - has a higher efficiency than a continuously variable transmission (60%) for fuel cell electric vehicles - meaning that the humble hydrogen hydraulic car gets a higher mileage than a fuel cell car, at significantly lower cost. At a design weight of only 850 lb, less than ¼ of a typical car, the OSE microcar focuses on moving the passenger, not a large chunk of metal accessory to the core purpose. Lighter cars have a good safety record. Before the S.U.V. boom, the country (USA) had the world&#039;s lowest highway death rate.http://www.nytimes.com/2004/05/05/business/averag e-us-car-is-tipping-scales-at-4000-pounds.html  Additionally, gas mileage for the OSE Microcar is specified for 100mpg. While not as testicular as a Tesla, the OSE specification requires higher self-esteem on the part of the driver to accept acceleration from 0-60 of 12 seconds, as opposed to under 3 seconds for a Tesla Model S.https://en.wikipedia.org/wiki/List_of_fastest_production_cars_by_acceleration&lt;br /&gt;
&lt;br /&gt;
Fig. The OSE Microcar concept.&lt;br /&gt;
&lt;br /&gt;
Can smaller cars are safer? This is controversial. https://www.ptua.org.au/myths/smallcar/  Physics says that energy of motion is proportional to v squared, and data shows that 56% of car deaths are single-car collisions. So unless you are going to hit another oncoming car or an immovable object like a large tree, your tiny car of under 1000 lb  has 36x less energy to dissipate than a Chevy Suburban of 6000 lb. And, the lightest car - the Smart Carfortwo at 1800 lb http://driving.ca/hyundai/accent/auto-news/news/these-are-the-ten-lightest-cars-you-can-buy-in-2015  and it certainly does get eaten up in a frontal 2 car collision with a larger car. And crashes took more than 37k lives in the US http://www.iihs.org/iihs/topics/t/general-statistics/fatalityfacts/state-by-state-overview#Crash-types  , with 20-50x more if injuries are counted. http://asirt.org/initiatives/informing-road-users/road-safety-facts/road-crash-statistics (are injuries better or worse in large cars?)&lt;br /&gt;
&lt;br /&gt;
But this is all before self-driving cars enter the scene - which have been tested for 0 driverless car crashes over 1.8 million miles by Google - with 13 fender benders caused by other cars. http://bigthink.com/ideafeed/googles-self-driving-car-is-ridiculously-safe  In other words, the case is there for super-small, super-efficient cars that are robotically controlled. &lt;br /&gt;
&lt;br /&gt;
What we have in mind follows the standard of the 200 mpg fuel efficiency of the VW  L1 first prototype car, at 640 lb weight, 8 hp, top speed of 75 mph, with tandem seating for 2. https://en.wikipedia.org/wiki/Volkswagen_1-litre_car. The efficiency dropped to 170 mph in a hybrid version - http://gas2.org/2009/09/14/volkswagens-diesel-hybrid-1l-concept-gets-170-mpg-available-by-2013/  If OSE achieves the same with 16 hp instead of 8 hp, and using hydraulics while not needing to go to a hybrid drive-train that apparently reduced its initial mileage performance - then we will have a major victory for open source-  Hydraulic accumulators may be used for peak power.  Plus, we’d like to achieve this with hydrogen as fuel in later versions.&lt;br /&gt;
&lt;br /&gt;
More specifically - our model is an H3E car - including a hybrid electric component.  The hydraulic component is a peak power electric-hydraulic micro-Power Cube of about 40 lb additional weight - powered by the onboard starter battery for its cranking amps.  This additional 30 seconds of a starter battery would double the power of the 16 hp engine - such that burst of energy for passing and sudden acceleration can be achieved easily.&lt;br /&gt;
&lt;br /&gt;
==B The Solar Car==&lt;br /&gt;
&lt;br /&gt;
The Solar Challenge is a fascinating event that shows PV-covered cars traveling 62 mph average across Australia. Granted that the driving is in expensive prototypes ad a sunny country - only in daytime - this still bodes well for the feasibility of solar transportation. The typical cars used are small - surface area of a Toyota Prius - and the OSE version would be twice as large 24x8 feet for 3kW of installed PV + 44 lb Lithium ion batteries + 2.5 kW small engine. http://opensourceecology.org/wiki/Solar_Car This allows for a total of 7kW of continuous power for one hour, or 4 kW total power continuous - at 750 lbs of weight. This just may work - if we 3D print a form frame for carbon fiber layup. 3D printing here may be the enabling technology.&lt;br /&gt;
&lt;br /&gt;
==Truck==&lt;br /&gt;
&lt;br /&gt;
The truck is a medium-size, hydraulic, 80 hp driven vehicle comparable to the Mercedes Unimog. https://en.wikipedia.org/wiki/Unimog  With a design top speed of 62 mph,  a weight of 6550 lb, and a hydraulic power take-off, the OSEmog could function as an agricultural tractor as well. The OSEmog is designed to accept a loader or various implements on the front or back. Using basic hydraulic circuits, the machine would have high and low gear, and speed cotrol via simple flow control valves.&lt;br /&gt;
&lt;br /&gt;
Fig. The OSEmog is a multipurpose truck for carryng loads or operating various implements. With off-the shelf parts, it is designed to be field serviceable, and the working hydraulic fluid can be grown - canola oil with additives.&lt;br /&gt;
&lt;br /&gt;
==Hydraulic and Electric Motors==&lt;br /&gt;
&lt;br /&gt;
Both the car have a choice of using hydraulic or electric drive. The advantages of hydraulics are low-cost, high torque, and simplicity of resulting drive design. Hydraulic motors cost only $10/hp, half that of electric motors - but a typical 40 hp hydraulic motor weighs about 50 lb http://opensourceecology.org/wiki/45.6_Cu_In_Hydraulic_Motor as opposed to about 350 lb https://inverterdrive.com/group/Motors-AC/TECA2-200L-4-Pole-B3-High-Efficiency-AC-Motor-200/ .  Typically electric motors are high speed and need to be geared down - whereas hydraulics can be used largely with direct drive. If high torque electric motors are used - these are more like $100/hp when the controller is included - making the drive system 10x as expensive for larger machines.  Electric motors are sensitive to moisture and dirt, while hydraulics are designed for dirty environments. &lt;br /&gt;
&lt;br /&gt;
We electric motors and generators - in solar electric power cubes - or in wind turbines. But the flexibility, power, and simplicity of hydraulics is a better choice for practical applications - especially when powered by hydrogen and transmitted by canola oil as the hydraulic fluid.&lt;br /&gt;
&lt;br /&gt;
The electric motor can also be 3D printed, making it fit with the OSE product ecology. &lt;br /&gt;
&lt;br /&gt;
Fig. A proprietary, 3D printed, 600W, 80% efficient electric motor. The equivalent is worthwhile to open-source.&lt;br /&gt;
&lt;br /&gt;
Electric motors can be both linear and rotary. In the linear form, they are known as solenoids - very useful devices that are used to make valves. For automation - we use dydraulic valves to control machines like the brick press - and solenoids are used wherever pneumatic or hydraulic controls are needed. This means any automated system - from the water control in aquaponics to the control of an industrial robot.&lt;br /&gt;
&lt;br /&gt;
The electric motor of interest ranges from a small 5W one to power a cordless drill - to the 50kW scale for use in the 50kW wind turbine.&lt;br /&gt;
&lt;br /&gt;
This brings us to the energy sector.&lt;br /&gt;
&lt;br /&gt;
=Energy Tools=&lt;br /&gt;
&lt;br /&gt;
The sun currently shines 10000 times more power to the earth than the entire civilization uses. The implications are profound: there is no such thing as an energy shortage. Energy scarcity is an imagined problem if we talk about actual availability of energy.&lt;br /&gt;
&lt;br /&gt;
We look at it as- it is a high priority to trap solar energy directly - by effective solar design of buildings (Homes and businesses spend about 50% of their energy on heating and cooling. )- and using photovoltaic energy (Solar Concentrator) to generate electricity locally, with wind (50kW Wind Turbine) wherever possible. For machines, the choice is to use hydrogen, charcoal, and compressed biogas. &lt;br /&gt;
&lt;br /&gt;
Hydrogen is by far the most efficient and clean when derived from water (as opposed to refining from oil and gas).  The process gives 0 pollution, and the product of hydrogen combustion is water. The OSE platform calls for provent internal combustion engines running on hydrogen as an immediately executable transition to a renewable energy future in transportation. Leading research institutes, such as the Rocky Mountain Institute (ref), promotes the hydrogen economy as the future, and hydrogen as a future energy source is not controversial if one assumes abundance of fuel feedstocks and distribution of energy production. Solar hydrogen can be produced anywhere, and wind hydrogen can be produced in most places around the world. We do not put such a high stake into batteries or supercapacitors when it comes to energy for cars, simply because chemical fuels are up to 140 times as energy dense. A typical energy density chart typically has chemical fuels off-the-charts good:&lt;br /&gt;
&lt;br /&gt;
Fig. Show specific energy density of storage media, with bats and caps, and chemical fuels, for perspective - https://en.wikipedia.org/wiki/Supercapacitor#/media/File:Supercapacitors-vs-batteries-chart.png. With supercapacitors having 100x less energy storage per weight than Lithium-Ion batteries, while costing 10x as much as ($2.85/kJ) as those batteries ($0.8/kJ), they are super-completely out of the question with today’s technology except for niche applications. Engines are .5kW/kg https://en.wikipedia.org/wiki/Power-to-weight_ratio#Engines  and Fuel (gas, diesel, methane) is 50MJ/kg and hydrogen is 140MJ/kg - or 50-140x more energy per weight than batteries. Given the environmental challenges of mining and recycling scarce metals, there is little case for battery-powered cars.&lt;br /&gt;
&lt;br /&gt;
That means that a non-battery car can lug around a higher percentage of payload (persons, cargo) rather than carrying around more car structure and batteries. &lt;br /&gt;
&lt;br /&gt;
For other purposes, biofuel pellets are desirable for heating fuel (after energy efficiency and solar thermal is maxed out) - such as by an aquaponic greenhouse with a black tubing heat exchanger.&lt;br /&gt;
&lt;br /&gt;
Biofuel pellets can be burned partly to release heat in winter - and if taken out of combustion after the volatile chemicals are burned off but before carbon burns to ash - then we have produced charcoal that can be used in a combustion engine. Thus, dual-fuel hydrogen/charcoal cars are in our view the transportation of the future. We are open to fuel cells entering the scene, and at $134/kW they are almost feasible.https://energy.gov/eere/fuelcells/fuel-cell-technologies-office-accomplishments-and-progress  They are too complex at this point for easy DIY production, so we may revisit this in 10 years if the technology becomes more accessible. Currently, fuel cells require exotic plastics and platinum, both of which are scarce resources. We are aiming for a sub $10k car which can be made with a standard internal combustion engine (ICE) running on hydrogen. Did you know that the first internal combustion automobile in the world ran on hydrogen in 1808? https://en.wikipedia.org/wiki/Fran%C3%A7ois_Isaac_de_Rivaz  Furthermore, ICEs are about 20% efficient - ICEs running on hydrogen are about 40% efficient. For comparison,  fuel cell vehicles are 50% efficient.http://environment.yale.edu/gillingham/hydrogenICE.pdf  Given that the efficiency gain of 25% of fuel cells over hydrogen ICEs comes at a 10x larger cost today, the case for pursuing hydrogen ICEs is much higher than the case for fuel cells. much cheaper H2ICE are seen by many experts as the means to provide a transition between emitting and non emitting transport and stationary system. https://pureenergycentre.com/hydrogen-engine/ &lt;br /&gt;
&lt;br /&gt;
Fig. The possible cost of a fuel cell car today for a 200kW sedan is $26k - and an overall minimum of about $75k. The open source hydrogen microcar is aimed at an under $10k cost and more than 100 mpg using widely available technology. (comparison of components and price, using ref 3 above)&lt;br /&gt;
&lt;br /&gt;
The answer already under our nose that is perhaps the most optimistic case for the energy revolution is solar power - at 0.015 cent per kilowatt-hour - demonstrated in 2016 by the Seed Eco-Home. http://opensourceecology.org/wiki/Hydrogen_Production  This is 4x cheaper than gas turbine electric generation  https://qz.com/135032/fuelcell-energy-fuel-cell-profit/  , and it allows for an equivalent 80 cent per gallon electricity cost for producing hydrogen.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
==The Power Cube==&lt;br /&gt;
&lt;br /&gt;
Our current Power Cube is a universal power unit that can power any of the large GVCS  machines, from cars to lathes to the brick press. The Power Cube is gasoline powered and has a 16 hp engine. We already ran this on charcoal gas - and as such - the same power cube can readily be used in dual-fuel operation - gasoline on the one hand, and charcoal on the other. Once we add the gas production infrastructure - the power cube can run on the hydrogen and biogas production from the House.  Because the pelletizer is part of the GVCS - we can make charcoal pellets from biomass pellets as a byproduct of space heating.  The concept of pellets is important - in that pellets are a flowable fuel. Meaning - that just like gasoline or tradition fuels - it can be stored in a tank and delivered as fuel as if it were a liquid - by using a small auger. This makes pellets a convenient fuel source, which unlike wood - can be used automatically in small machines.&lt;br /&gt;
&lt;br /&gt;
Moreover, the Power Cube can be run on solar energy, allowing for autonomous tractors and solar cars to enter. Solar power cubes are a good idea for shop power - where PV on the workshop roof feeds electric power cubes for hydraulic shop power. Power cubes can also be made very small - on the 1 kilowatt scale. They can also be stacked readily for higher power, so if we want a 160 hp bulldozer, we can do that based on our existing Power Cube.&lt;br /&gt;
&lt;br /&gt;
The Power Cube involves developing open source engines so that they enter the realm of lifetime design public technology. A universal version of an open source engine means that such an engine could be maintained and produced in a distributed fashion, bringing it closer to appropriate technology with a lifecycle that includes more reusability of parts.&lt;br /&gt;
&lt;br /&gt;
Fig. The Power cube and its different fuel sources - from gasoline, to charcoal, to compressed biogas, hydrogen, and electric.&lt;br /&gt;
&lt;br /&gt;
The large torque of hydraulics makes them very flexible for driving a wide range of machines. A small power cube, such as a 300W version running on a single solar panel, can be used to drive a 2000 lb MicroTrac as a practical, autonomous tractor.  The idea is that the machine would move very slowly - all day - on solar power. This is afforded by that fact that hydraulics have high torque at any speed - making this a perfect application of solar energy to autonomous, robotic tractor drive via a small microcontroller such as a $10 Pi Zero with Wireless.https://www.adafruit.com/product/3400   Thus, we can pull chicken tractors or pig tractors with a solar robotic tractor for a diversified agriculture operation.&lt;br /&gt;
&lt;br /&gt;
Fig. Infographic. Mega power cubes for 160 hp for a bulldozer, and a micro power cube for a solar grinder/pelletizer or chicken tractor.&lt;br /&gt;
&lt;br /&gt;
Autonomous animal tractors are another possible application of Power Cubes…&lt;br /&gt;
&lt;br /&gt;
Fig. The economic breakdown of an autonomous chicken tractor. PV panel + micro power cube at $500, plus the tracked drive for another $500 with open source hydraulic motors. The hydraulic motors (SME) are produced on the open source lathe (SME).&lt;br /&gt;
&lt;br /&gt;
==The Gasifier ==&lt;br /&gt;
&lt;br /&gt;
The OSE  gasifier is a device that converts charcoal into gas for fueling engines. Note that this gasifier uses charcoal that is produced as a byproduct of space heating. The gasifier is a metal container filled with charcoal, which upon being lit via in a small burn zone with an air inlet - burns and produces gas. This gas can be used as fuel in a regular internal combustion engine. The power of this lies in that with minimal modifications, a standard engine can be fueled by charcoal - which is derived from wood or other biomass.  This means that wherever plants grow - they provide a distributed and practical fuel source byond oil wars. https://www.cnn.com/2013/03/19/opinion/iraq-war-oil-juhasz/index.html  To produce charcoal, biomass is first pelletized. Burning pellets for space heat - and removing them from the burn before they turn to ash - produces charcoal pellets.&lt;br /&gt;
&lt;br /&gt;
Fig. Infographic. Space heating produces charcoal in the OSE ecosystem.  The Gasifier vaporizes charcoal, which is then burned in a standard engine. This process can be used to fuel cars - no engine modification required.&lt;br /&gt;
&lt;br /&gt;
The first reaction may be that if we turned plants into vehicle fuel - then we would destroy all of nature. That is not true, because there is plenty of biomass reserve that can be used to fuel the entire American car fleet, which uses about 60% http://needtoknow.nas.edu/energy/energy-use/transportation/  of all the energy in the transportation sector. Did you know that the largest single crop in the United States is lawn? There are 40 million acres of turf grass. http://scienceline.org/2011/07/lawns-vs-crops-in-the-continental-u-s/  What if we turned lawns into fuel crop, while increasing esthetics and reducing herbicides? Yields of grass are 4 dry tons per acre https://en.wikipedia.org/wiki/Biomass  - and if charcoal is produced at 25% efficiency - that is one ton of charcoal per acre - or 40 million tons of charcoal can be harvested from lawns alone, with no effect on food production, while increasing the ecological diversity of lawns. The average american uses 500 gallons per year of fuel.  https://www.treehugger.com/culture/pop-quiz-how-much-more-gas-do-americans-use.html  Lawns could thus provide ¼ of the entire car fleet fuel in the USA! (Charcoal is ¾ the energy content of gasoline by weight. At about 3 kg/gallon - 500 gallons is 1500 kg- about 1.5 metric tons - so 33M people could be supplied by fuel from lawns. If 95% of households have cars - https://photos.state.gov/libraries/cambodia/30486/Publications/everyone_in_america_own_a_car.pdf - and household is 2.6 - there are about 120M drivers in the USA. Thus  - ¼ of US drivers can be fueled by lawns.) This is at the crappy USA 23 miles per gallon - so increasing fuel efficiency to 100 mpg https://www.motherearthnews.com/green-transportation/green-vehicles/build-your-own-car-zm0z13amzmar with super-efficient micro-cars could mean that the entire US car fleet is supplied by fuel from grass. Efficiency and ecology - as opposed to battery technology with questionable environmental side effects and its centralization based on scarce resources - make the OSE platform converge on biomass and hydrogen as the fuels of choice. The OSE platform reserves the role of batteries only as a small part of vehicular power, not the backbone of the auto industry. &lt;br /&gt;
&lt;br /&gt;
The biomass route needs no technical invention to realize - today - and is also a carbon-neutral route. From the OSE perspective - hydrogen is clean (it produces water as the byproduct) but not better on ecological grounds (it does not contribute to biological ecology) - but it is much better on efficiency grounds.&lt;br /&gt;
&lt;br /&gt;
When discussing biofuels, it is important to point to the food-fuel-fiber integrated agroecology route as the preferred OSE route to agriculture. As opposed to genetic engineering to produce super-crops, the OSE platform favors ecological integration over genetic manipulation - so that we avoid creating super-problems at the same time. The ecological route means that we learn more about dealing with integrated ecosystems, not trying point solutions (genetic engineering) as a cure. When dealing with powerful technologies like genetic engineering, we must pay attention to unintended consequences. The current economic paradigm of profit maximization is not compatible with care in the use of genetic engineering. We favor increasing productivity by stacking yields of multiple crops that work harmoniously in a polyculture setting - with tree crops as a significant component. For us, the breakthrough work of Badgersett Research Farm is seminal in providing this leadership. They are developing perennial crops (hazelnuts and chestnuts) that could serve as a viable replacement for soybeans and corn. (ref).  Hazelnuts and chestnuts provide the same nutrition as their annual counterparts - but are perennial - and therefore do not contribute to the average 4 ton per acre annual soil erosion in the United States. (ref). Let me repeat that - the avarage topsoil loss in the United States - per acre - is 4 tons. What that means is that agricultural soils today are so depleted that they could not grow crops if it were not for the heavy inputs of fertilizers. The biological activity of commercial farmland is severely depleted (ref), not sustaining the soil food web of microbes that bring fertility back to the soil. (ref). Our proposition for perennial polyculture - is not new (ref on seminal works, Tree Crops, Regrarians, etc) - and it can produce food, fuel, and other materials.&lt;br /&gt;
&lt;br /&gt;
To improve the world, all you need to do is plant trees. Desertification still claims an additional ______________ square miles every year, and it would be good to reverse that.&lt;br /&gt;
&lt;br /&gt;
It takes less than 60x the land area to produce solar hydrogen compared to the land area required to grow biofuel crops.  Between biofuel (easy) and hydrogen (hard), humanity’s fuel needs can be met. Let’s look at numbers: we already said 300 gallons of fuel equivalent per acre (enough to fuel one car for a year at a fuel economy of 40 MPG https://www.google.com/search?q=average+miles+per+year+usa&amp;amp;oq=average+miles+per+year+usa&amp;amp;aqs=chrome..69i57j0l2.7415j0j7&amp;amp;client=ubuntu&amp;amp;sourceid=chrome&amp;amp;ie=UTF-8 ) fuel consumption -  roughly one gallon per day. If we apply this to hydrogen - 50kWhr of electricity is required to produce 1 kg of hydrogen, roughly one gallon gas equivalent. This can be obtained from a 9 kW PV array - running 6 hours per day - 54kWhr. The space required for a 9 kW array is 60 square meters if the panels are 15% efficient. An acre is 4000 square meters - so producing solar hydrogen requires 66 times less land area than growing the equivalent grass. Our materials cost for 9 kW of solar panels is under $9k. So one can obtain 20 years of hydrogen fuel for a PV investement cost of $17k.&lt;br /&gt;
&lt;br /&gt;
Fig. Home hydrogen production. The OSE open source goal is $9k for PV panels, $2k for storage, $2k for pump, $2k for plumbing, and $2k for the electrolyzer. That is $17k for a lifetime supply of hydrogen. Compare to gasoline - $1250/year on average. Payback time for  home fuel station is 14 years in the USA and 7 years in Europe. We intend to make hydrogen production a standard feature of the Seed Eco-Home.&lt;br /&gt;
&lt;br /&gt;
Add a paragraph about renewable energy plantations - perennial polycultures for fuel, food, fiber. &lt;br /&gt;
&lt;br /&gt;
Fig. Basic economic model for renewable energy plantations involves $x/acre in coppiced fuel, $1000/acre in nuts, and $2k/acre in sustainable chickens that fertilize the crop via autonomous chicken tractors.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
==Heat Exchanger==&lt;br /&gt;
&lt;br /&gt;
The heat exchanger is a device that takes heat from one medium and puts it into another. For example, in the Seed Eco-Home - we have a hydronic stove with heat exchanger which is used to heat water for heating the house.&lt;br /&gt;
&lt;br /&gt;
Fig. Hydronic stove with heat exchanger. A heat exchanger heats water, and if that water is boiled, it can be used to run a steam engine or turbine. Small steam engines have been used for shop power 100 years ago, and they can be used even more effectively today. You can get a working kit for $275 on Ebay.&lt;br /&gt;
&lt;br /&gt;
Simpler examples of the heat exchanger are the Hillbilly Heater. This device traps solar heat and puts it into water circulating through the black tubing. This energy is released through another coil in the aquaponic ponds, for example. A closed heat exchanger means that the water in the black tubing does not mix with the pond water. Or, this heat exchanger could be an open heat exchanger, where the water is heated and then used as hot water in a shower - so that a steady supply of new water is fed through the exchanger instead of just circulating - as in the pond heating case.&lt;br /&gt;
&lt;br /&gt;
Fig. The hillbilly heater can be used to heat ponds or to provide hot water for the house.&lt;br /&gt;
&lt;br /&gt;
==Modern Steam Engine==&lt;br /&gt;
&lt;br /&gt;
The modern steam engine is an engine that produces power from steam. The industrial economy was created by steam power. And steam turbines are the main way that power is generated today. &lt;br /&gt;
&lt;br /&gt;
A modern steam engine is a small engine that makes sense to build wherever space heating is involved. For example, a centrally heated building could be generating power at the same time as its being heated - if a heat engine with a generator is added to the system. Thus, we are piggy-backing on an existing power source, while using all the waste heat.&lt;br /&gt;
&lt;br /&gt;
Under 500 hp - or in any small scale installation - it is more effective to have a steam engine as the engine of choice. Above 500hp, it is more effective to use a steam turbine. Large power plant steam turbines reach 50% efficiency. https://en.wikipedia.org/wiki/Steam_turbine#Practical_turbine_efficiency &lt;br /&gt;
&lt;br /&gt;
A flame-fired or solar-powered heat exchanger can produce steam - for electricity generation. This makes sense for combined-heat-and-power systems. Most of today’s electricity is produced by water that is boiled in power plants to provide electricity via steam turbines. (ref) This can be done effectively on a scale of 500 or more horsepower - which is village scale, not home scale. For the smaller scale, a small steam engine can be used. For this reason, we have incorporated a modern steam engine into the GVCS - as a machine for producing electricity on top of a heat source. This could be done in our hydronic stove - where the water goes from the steam engine and then to house heating after some power has been extracted for electricity. It makes sense to convert the heat into high grade electricity - when the steam engine is connected to a generator.&lt;br /&gt;
&lt;br /&gt;
Fig. Hydronic stove with power generation.&lt;br /&gt;
&lt;br /&gt;
Did you know that the modern steam engine - a specific advanced version -  is more efficient than the internal combustion engine? The Cyclone engine is a high tech, high temperature steam engine made of stainless steel and exotic materials - with thermal efficiency over 30%. http://cyclonepower.com/ &lt;br /&gt;
&lt;br /&gt;
There is another steam engine that received a lot of attention on the internet but appears not to work well - the Green Steam Engine. We do not endorse the engine, as suggested by Tom Kimmel of Kimmel Steam Power  http://kimmelsteam.com/green-robertengine.html  - and you can read more in an old blog post. (http://opensourceecology.org/steam-meet-report/ . I have since contacted Mr. Greene for data on Feb 1, 2018, but I have not been presented with any data.)&lt;br /&gt;
&lt;br /&gt;
All together, the modern steam engine is valuable for household power, if the Power Cube is used for mobile power. Would would be the cost of a steam engine add-on to a household infrastructure? Small models of ¼ hp are available for under $300 in parts, (http://ebay.to/2EwmHWt ) and these are scalable readily to larger sizes. The current seed eco-home stove has sufficient power to run this engine, so only an additional pump would be required to feed water to this system.&lt;br /&gt;
&lt;br /&gt;
Integration of such a system would work well if pelletized biomass were used as fuel - and subsequently - charcoal would be produced for use in cars as a byproduct of household power generation. An interesting milestone would be an automated biomass energy system from an autonomous tractor-pelletizer - up to the production of charcoal as car fuel using gasifiers - all from one’s former lawn converted to bioenergy crop.  In such case, nickel iron batteries may be desirable in so far as excess energy storage from daytime solar power.&lt;br /&gt;
&lt;br /&gt;
Fig. The energy product ecology of the Seed Eco-Home includes solar hydrogen, biogas for cooking, and production of car fuel from the lawn.&lt;br /&gt;
&lt;br /&gt;
==Solar Concentrator==&lt;br /&gt;
&lt;br /&gt;
The modern steam engine equation becomes much more exciting when solar concentration is used. Using 30% efficient, modern steam engines, proven linear solar concentrators, and a night-time storage system based on large, insulated propane tanks with hot water - it is possible to produce an off-grid energy system with $100/kWhr energy storage costs - 4x cheaper than lithium ion batteries. https://en.wikipedia.org/wiki/Lithium-ion_battery  A breakthrough company - Terrajoule - has already demonstrated this. Then the question becomes - if this has already been shown in the first prototype of Terrajoule, why isn’t everyone doing this when the technology is all proven? One cannot beat the simplicity of water and solar heat as the ultimate storage medium. &lt;br /&gt;
&lt;br /&gt;
What can water really do? When water is heated but not allowed to expand, it turns to what is known as saturated water. A saturated liquid is a liquid whose temperature and pressure are such that any decrease in pressure without change in temperature causes it to boil. In other words, if a tank was not holding the water at pressure - that water would turn into steam.&lt;br /&gt;
&lt;br /&gt;
Just how much energy can that water store at a medium pressure? A lot. Looking at the total heat content of water that would otherwise turn to steam, but is held under pressure at 18 atmospheres (250 PSI) in a tank instead http://opensourceecology.org/wiki/Saturated_Water  - we see that each kilogram of such saturated water holds about ¼ kWhr of energy. That means that a 10,000 gallon propane tank can store about 4MWhr of energy! We can extract that energy with a modern steam engine, where steam engines from the 1950s got to about 30% efficiency. https://en.wikipedia.org/wiki/Uniflow_steam_engine   After all the losses, we we would have 300kWhrs of electricity when the modern steam engine runs a generator.&lt;br /&gt;
&lt;br /&gt;
We can scale that down to a residential system - just a 1000 gallon propane tank - and 30kWhrs of electricity produced.&lt;br /&gt;
&lt;br /&gt;
Fig. Cost and energy of a home-scale solar energy storage system using water and modern steam power. From energy content of 400kWhrs to 30kW hours of electricity is quite doable using proven technologies, at ¼ the cost of battery storage.&lt;br /&gt;
&lt;br /&gt;
==Nickel Iron Battery==&lt;br /&gt;
&lt;br /&gt;
Nickel-Iron Batteries are long-life batteries that have a track record of lasting 50 or more years. Unlike other batteries, these can be discharged fully without decreasing their lifetime. These are chosen for the Global Village Construction Set specifically for their long life - and becuase nickel and iron are not scarce resources. While heavier and 2x more expensive than lithium ion batteries, (Read an intereresting pro-con discussion - http://opensourceecology.org/wiki/Nickel_Iron_vs_Lithium_Ion_Battery_from_Tesla_Motors ) they make up by their long lifetime, and lend themselves to decentralized production. New developments are in progress, ( https://news.stanford.edu/news/2012/june/ultrafast-edison-battery-062612.html )  though OSE does not rely on new developments for feasibility given that OSE internalizes social and environmental aspects for true cost accounting. The cost is currently high because production volume is low - only 2 US manufacturers. Based on a nickel price of $6/lb and iron at 25 cents/lb, and a weight of 100 lb for 1kWhr - and a 20% content of nickel in nickel iron batteries https://www.solarpaneltalk.com/forum/off-grid-solar/batteries-energy-storage/ni/7052-how-much-nickel-is-really-in-a-ni ckel-iron-ni-fe-battery - the base materials cost of materials in Nickel Iron batteries appears to be $150/kWhr. That is similar to lead acid batteries and ½ of lithium ion costs - but if the lifetime of these batteries is really 50 years, then they are 5-10x cheaper than other batteries based on lifetime.&lt;br /&gt;
&lt;br /&gt;
According to recent research: https://link.springer.com/content/pdf/10.1007/s10800-015-0911-3.pdf &lt;br /&gt;
&lt;br /&gt;
There are many reasons favouring the use of NiFe cells as cost-effective solutions to store grid-scale amounts of energy, such as low cost of raw materials, environmental friendliness, electrical abuse tolerance, long life (in the order of thousands cycles of charge and discharge) and compatibility with photovoltaics (PVs). Due to the nature of the heavy metals involved in its construction this technology is suitable for stationary low gravimetric energy applications (30–50 Wh kg-1 ). As a consequence, there are good reasons to foresee a large scale utilization of this technology. Due to their outstanding safety properties (zero flammability, fail safe, no over/ under charge), low cost and long lifetime, we anticipate that they will receive widespread public acceptance for customer-connected energy storage.&lt;br /&gt;
&lt;br /&gt;
It is our hope that the nickel iron battery would be only a small fraction of electrical power storage needs in the future - such as replacing 5-year lifetime starter batteries in vehicles. For night time electricity, it would be useful for warmer regions to use solar concentrator saturated water storage - as one possibility - or solar hydrogen as another.&lt;br /&gt;
&lt;br /&gt;
In colder areas, biomass is typically available as an abundant energy crop - where PV may not be adequate if there are weeks without sun. The exact mix of solar concentrator electric, PV, wind, charcoal, biomass, biogas, and hydrogen is to be determined at Factor e Farm as we measure the value of all these systems side by side. The main requirement for OSE is true service to humanity, environmental regeneration, and freedom from resource conflicts.&lt;br /&gt;
&lt;br /&gt;
==50 kW Wind Turbine==&lt;br /&gt;
&lt;br /&gt;
A wind turbine converts a renewable form of energy - wind - into electricity. It provides a good backup to PV electricity, as wind typically blows when the sun is not out.&lt;br /&gt;
&lt;br /&gt;
We propose a vertical axis wind turbine for the initial OSE version based on integration with hydraulics and the Universal Rotor.  A simple system can consist of a pole mounted 40 hp hydraulic motor ($400), serving as a pump - which transfers fluid power to an on-the-ground hydraulic motor ($300) + 24 kW generator ($1000). The power generator related costs are ~ $2000 here, and the rest is the tower and structure. With $6k spent on the materials for this wind turbine, this would be $250/installed kW in materials costs - with installation being 15% on top of this http://www.esru.strath.ac.uk/EandE/Web_sites/14-15/XL_Monopiles/cost.html  - a very attractive package in a sweet spot of cost for readily-available components. This is compared to $1590/kW standard costs of large scale wind installations. https://www.awea.org/falling-wind-energy-costs &lt;br /&gt;
&lt;br /&gt;
The OSE design features a generator that is mounted on the ground, with only the hydraulic motor on top of the tower. This facilitates maintenance considerably. The savings is due in part to the great simplification of the nacelle - in the OSE case, the vertical axis design doesn’t have a yaw mechanism - it’s just a hydraulic motor that accepts wind from any direction. These turbines are not as efficient in terms of wind capture as they are lower to the ground - but the low capital + maintenance costs make up for the lower efficiency. Because they can be packed more tightly in the same area, however - VAWT wind farms can actually produce 10x the energy of a propeller-type wind farm. https://en.wikipedia.org/wiki/Vertical_axis_wind_turbine#Advantages  They also self-regulate their speed, so they do not need a braking meachanism for overwind conditions.&lt;br /&gt;
&lt;br /&gt;
Fig. OSE VAWT concept. Simplification of design include ground-mounted generator, yawless rotor, screw pile foundation https://en.wikipedia.org/wiki/Screw_piles#Modern_Use_and_Benefits  , and braking via the hydraulic motor as the overspeed protection. The wind turbine module is designed for 24 kW, and it includes the Electric Motor/generator, Universal Rotor, Hydraulic Motor, Power Cube, and Universal Power Supply for managing power.&lt;br /&gt;
&lt;br /&gt;
8. Universal Power Supply&lt;br /&gt;
The Universal Power Supply (UPS) is the last of the energy machines. It is a universal device for powering large electronic machines - induction furnaces, welders, plasma cutters, laser cutters - and for controlling power delivery and transmission to homes or electric cars. It is also used for charging. The UPS has feedback such that it would know when batteries are full, or for optimizing the power transfer into a load of metal that is melted with the induction furnace. &lt;br /&gt;
&lt;br /&gt;
The Universal Power Supply in general  converts AC and DC into voltages and currents of any amplitude and frequency. The UPS is scalable from a few watts to 20kW based on the same design of modules.  The Universal Power Supply can also be used to condition power from the wind turbine or PV system and pump it into the grid. It can also be used as an inverter to convert DC to AC, or it can be used to control the speed of an electric car. It can also be used to step power up to high voltage for power transmission over longer distances, such as up to the 69,000 volts for rural power lines. &lt;br /&gt;
&lt;br /&gt;
As with the mechanical machines, the Universal Power Supply is based on modular design, such that we can arrive at a Construction Set. Just like power units, wheels, shafts, hydraulic motors, control valves, and frames can create any mechanical industrial machine, so can a small number of modules provide just about any electrical power function in the Universal Power Supply. These modules are mainly: a microcontroller, a current measurement device, a transistor, wires, laminated cores, ferrite beads,  diodes, optocouplers, resistors, capacitors, and inductors - plus a few mechanical components such as plugs, cases, cooling systems. With advanced transistors that now cost $1 per kW of power handling, large power electronic devices can be built on the cheap if open source knowhow is available.&lt;br /&gt;
&lt;br /&gt;
Wires and metal cores themselves produce a wide range of devices: inductors, transformers, relays, solenoids, switches for large currents, electric motors, spark generators, electromagnets, and other devices. &lt;br /&gt;
&lt;br /&gt;
Lasers, charge controllers, inverters, welders, induction furnaces, plasma cutters, oxyhydrogen generator power supply, and motor controllers are all functions that can be generated with the Universal Power Supply. These are all based upon currents and voltages at different frequencies and amplitudes that perform radically different functions. This has to do with the nature of electricity - jus like a few atom types (100 or so) make up millions of different substances that are all around us - so can electricity be manipulated to perform a wide array of functions. Any of the above devices consist of a microcontroller and a power transistor - along with some resistors, capacitors, and inductors. The microcontroller could be an Ardduino or a Rasperry Pi - which now cost as little as $5 for these small computers running with a 700MHz cpu. This CPU - via software - can produce a voltage of any amplitude and frequency using transistors. In other words - a ‘brain’ - the CPU - can massage electrons so they maifest at any voltage or frequency - by using transistors - or devices where a small signal from a CPU controls a large voltage. Essentially - a transistor is a switch - which is activated by a small signal.&lt;br /&gt;
&lt;br /&gt;
For example - taking DC voltage - one can make it pulsed and appear as an oscillating sine wave. This is an inverter for household power - which can for example take electricity from PV cells and convert that into household current. Or - this same inverter can be pulsed much faster to create a 30kHz voltage used in an induction furnace. And regulation can happen - such as an induction furnace delivering power most effectively to the molten charge - when the same microcontroller can measure the voltage, and change the frequency of the applied voltage to pump power more effectively into the melt. &lt;br /&gt;
&lt;br /&gt;
This is all possible because superfast microcontrollers, and high power handling transistors - can all be purchased now for a few dollars.&lt;br /&gt;
&lt;br /&gt;
Energy Summary&lt;br /&gt;
&lt;br /&gt;
Combining biomass, charcoal, biogas, wind power, the solar concentrator,  steam electricity, hydrogen, PV - and the electronic controls of the Universal Power Supply -  makes for a resilient power infrastructure without necessitating resource conflicts.&lt;br /&gt;
&lt;br /&gt;
=Open Source Microfactory=&lt;br /&gt;
&lt;br /&gt;
The Open Source Microfactory (OSM) is the crown jewel of the Global Village Construction. It is the part that allows for GVCS self-replication - in that the Open Source Microfactory allows for the production of all the  GVCS tools - including the Microfactory itself..&lt;br /&gt;
&lt;br /&gt;
The Open Source Microfactory is broken into 2 main parts: precision CNC tools, and metal production tools. The CNC tools - which stands for Computer Numerical Control - are automated machines that can be programmed to build things - from small parts, to engines, and everything in between. The metal production tools allow for the production of virgin steels from scrap. The steel that can be produced with the GVCS metal tools thus allows for the creation of advanced civilization - wherever there is access to scrap steel. Scrap steel is abundant, and so it iron ore from which steel is made. Iron is the 4th most abundant element in the earth’s crust - after oxygen, silicon, and aluminum. https://en.wikipedia.org/wiki/Abundance_of_elements_in_Earth%27s_crust &lt;br /&gt;
&lt;br /&gt;
What if there is no scrap steel available? We can go to aluminum - which is even more abundant in terms of the crust’s composition. Aluminum is found in common clay. Clay is aluminosilicate, from which aluminum can be extracted. Because Aluminum is so abundant - the GVCS goes so far as the extraction of aluminum from clay. This is intended to break through any notions of scarcity in today’s civilization.  Clay is abundant, and it’s an essential part of the GVCS: compressed earth blocks, soil for growing food, clay for 3D printed pots and cookware - in addition to the production of aluminum metal.  &lt;br /&gt;
&lt;br /&gt;
Fortunately - silicon is even more abundant. We get solar cells for producing electricity from silicon - a core technology for the GVCS such as in the Seed Eco-Home. In less than the time it takes to read this paragraph, the sun will have provided as much energy to Earth as used by all of human civilisation in one day. Thus silicon solar cells are important. And silicon is used to make semiconductors - so silicon creates the computer age.&lt;br /&gt;
&lt;br /&gt;
With the Open Source Microfactory - we thus aim to show that literally, modern civilization may be created -  from dirt and twigs. This can happen on any parcel of land - as solar cells can easily produce about 500kW of energy - from an acre. So a facility such as the OSE headquarters can produce all the technology required to produce an advanced civilization. For example, 500kW of solar energy - or 3MWhrs per 6 hours of daylight - can produce 200 kg of aluminum per day. Aluminum requires 15 kWhr per kilogram to smelt. (http://wordpress.mrreid.org/2011/07/15/electricity-consumption-in-the-production-of-aluminium/ . This one says ,05 GJ/kg - http://wordpress.mrreid.org/2011/07/15/electricity-consumption-in-the-production-of-aluminium/ )Aluminum is energy intensive - but its production may one day be improved for more environmentally-sound production - as can any other process by internalizing environmental costs.  https://www.sciencedirect.com/science/article/pii/S0360544207001065#! &lt;br /&gt;
&lt;br /&gt;
This shows how energy intensive aluminum production is - but its 3x better weight to strength ratio compared to steel makes it a desirable product. With the proposes 200kW solar microfactory - we can produce 80 kg of aluminum per day. That’s not a lot - but acceptable as a proof of concept for an appliance-size machine.&lt;br /&gt;
&lt;br /&gt;
Aluminium is the most abundant metallic element in the Earth’s crust (about 8%) and the&lt;br /&gt;
second most widely used metal next to steel. The aluminum production process involves taking ordinary clays such as abundant kaolin clay - and leaching out alumina with hydrochloric acid to produce Al203, which is subsequently turned to Aluminum via electrolysis at a cost of 15 kWhr per kg of aluminum produced. For reference in terms of energy requirements - this is like converting one gallon of gasoline to one kg of aluminum. That’s a lot of energy. But the main point here is that this can be done anywhere where there is soil - clay for making aluminum is an abundant feedstock.&lt;br /&gt;
&lt;br /&gt;
If we talk about the carbon dioxide emissions - whether from aluminum or steel production - the way we propose to make it sustainable is to make the CO2 recyclable. If the carbon involved in the reactions for producing metals - or for that matter any other product - comes from charcoal derived from biomass - then the industrial process is regenerative as the plants that were used to produce the charcoal took the carbon out of the atmosphere in the first place. Thus, a sustainable industry is possible  when civilization evolves to using charcoal  instead of fossil fuels. &lt;br /&gt;
&lt;br /&gt;
However, it should be stated that CO2 in the long run may be more advantageous for ecology - even from fossil fuels - if that CO2 yields more plant growth. While many people see CO2 per say as a global warming problem - it is also possible that the CO2 will make the earth more green. Nobody knows what will happen at this point - we can only speculate as to the long term effects of increasing CO2 in the atmosphere. &lt;br /&gt;
&lt;br /&gt;
The open source microfactory is intended to produce an entire technosphere from local resources, pushing the limits of what can be done:&lt;br /&gt;
&lt;br /&gt;
Fig. Open Source Microfactory cyclic material flows can be based on local resources. Metals, bioplastics, ceramics, PV cells, concrete, carbon, hydrogen, glass, rubber, fuels, food, construction materials, and many other chemicals can be produced from local abundance.&lt;br /&gt;
&lt;br /&gt;
If it is indeed that PV cells can be made from local sand, and aluminum from clay - and everything else as noted - then we have truly stepped into a world of post-scarcity. At the point where material production is guaranteed, it may be possible for people to evolve full time - without being held back by mere survival. That is the essence of society that OSE intends to create - one in which material needs are not in the way of human evolution.&lt;br /&gt;
&lt;br /&gt;
For any other processes of industry - the Open Source Microfactory can provide. If you can make buildings, glass, metal, and plastics + other materials - you can build anything. Advanced processes such as chemical plants or semiconductor fabs - are nothing but buildings, metal vessels, motors, vacuum pumps, and a few other basics - and from there spews out any product - in a nutshell. This does not even involve the nanotech of molecular manipulation - where it is deemed that in the future we will be able to synthesize substances by moving atoms directly - without regard for chemical reactivity as we know it today. Yet we do not invoke the Technological Singularity as a prerequisite for meeting all human needs.&lt;br /&gt;
&lt;br /&gt;
Let’s move to the specific tools in the Open Source Microfactory:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
And &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Fig. Tools of the Open Source Microfactory. They include everything needed to produce precision metal parts starting from scrap metals, glass, bioplastics, and even semiconductors for solar cells. &lt;br /&gt;
&lt;br /&gt;
==Universal Axis==&lt;br /&gt;
&lt;br /&gt;
Six of the Open Source Microfactory tools are based on the Universal Axis. The Universal Axis is a modular, and scalable CNC axis which can be used to create cartesian CNC machines. The core of the axis design is belt drive and linear motion rods where carriages are pulled on the rods. The system is scalable to any size and number of axes, including rotary axes. The system uses a combination of 3D printed parts, metal plates, and belt-driven shafts. Applications include 3D printers, CNC torch tables, heavy duty CNC machines, and many other production machines.&lt;br /&gt;
&lt;br /&gt;
We intend to use the 5/16”, 1”, and 2” versions for 3D printers, CNC torch tables, and heavy duty CNC machines - which are among the key machines that can be built with the system - though a variant of any size and shape can be designed.&lt;br /&gt;
&lt;br /&gt;
Fig. The universal axis comes in 5/16”, 1”, and 2” variations, and is based on belt drive, though a screw and nut system can also be used as a drive. Various tool heads can be attached. Non-contact tool heads are attached magnetically, such as the laser cutter and 3D printer. Rotary attachments can even be used for 3D scanning or indexing.&lt;br /&gt;
&lt;br /&gt;
For heavy duty applications, the plastic plates may be reinforced with steel plates - making a steel-plastic composite that has the required strength - while being easy to produce because the complex geometry is 3D printed. The metal plates themselves can be CNC cut using the CNC torch table. This allows for the lowest cost route - the 2” bushings capable of 8000 lb force on these axes currently cost only $9.41 at McMaster Carr.&lt;br /&gt;
&lt;br /&gt;
Fig. Metal-plastic Universal Axis System.&lt;br /&gt;
&lt;br /&gt;
The power of the universal axis lies in its flexibility. The same design of the drive system can be used to make an unlimited range of fabrication machines, putting the manufacturing process completely in the hands of anyone - without high barriers to entry. This is aimed at the Open Source Microfactory in every town, where our goal is to distribute at least 10,000 of these open source microfactories around the world, each generating at least $100,000 of net revenue per year. Once production returns to communities, we expect that taxes will go down as communities once again become responsible for their own prosperity.&lt;br /&gt;
&lt;br /&gt;
==The 3D Printer, Bioplastic Extruder, 3D Scanner==&lt;br /&gt;
&lt;br /&gt;
The 3D printer is a machine with diverse applications. Essentially, the technosphere is made from plastics, ceramics, and metals. 3D printers can print with all of these, and are as such ubiquitously applicable to manufacturing of all sorts. Currently, it is easy to print with all kind of plastic, including rubber for printing tires and polycarbonate for printing glazing. It is likewise easy to print ceramics - by printing clay and then baking it. Here we can produce ceramic cookware or clay parts such as insulators or building bricks. If the clay contains a large fraction of glass or metal - then upon kilning - 3D printed glass and metal objects can be printed as well. Metal printing can also happen via a MIG or TIG welder as the working toolhead - where large metal structures can be printed additively like this. If we go a step up to lasers - we can do selective laser sintering of any kind of powder - from plastic, to ceramic, to metal. Extremely strong, precise metal parts can be created this way - such that for example the rocket engine for Elon Musks’s SpaceX rockets has been 3D printed.&lt;br /&gt;
&lt;br /&gt;
Fig. Different applications of 3D printing: plastic, rubber, glass, metal, ceramic, and housing.&lt;br /&gt;
&lt;br /&gt;
Carbon fiber or metal fibers can also be embedded in plastic 3D prints to make the parts as strong as aluminum. 3D printing can also print ceramic molds which can then be used for casting directly into these molds - using either molten metal from an induction furnace or a MIG weld right into the metal form.&lt;br /&gt;
&lt;br /&gt;
Fig. Apparatus for automated metal casting using 3D printing of molds + induction heating of melt to fill the molds.&lt;br /&gt;
&lt;br /&gt;
Currently - open source printing includes  plastic + rubber 3D printing, welder 3D printing, clay printing for ceramics, clay-metal 3D printing for metals, selective laser sintering of plastics, and 3D priting of concrete or clay buildings. With a little bit of work,  the full printing with metal or glass using selective laser sintering can be developed by using off-the-shelf technologies. An 80W laser tube like in the Laser Cutter + shielding gas allows for selective laser sintering of off-shelf metal powders. http://opensourceecology.org/wiki/Metal_Selective_Layer_Sintering#Literature &lt;br /&gt;
&lt;br /&gt;
Fig. If metal powder is available (it is, such as iron at $1/lb) - then we can use a laser to fuse a powder bed to complex 3D objcts that cannot be produced in any other way.&lt;br /&gt;
&lt;br /&gt;
The world of 3D printing is in its infancy - and this is definitely worth refining to achieve full 3D printability in any material. Perfecting all of the above 3D printing can go far towards local production of just about anything.&lt;br /&gt;
&lt;br /&gt;
==Bioplastic Extruder==&lt;br /&gt;
&lt;br /&gt;
The Bioplastic Extruder is part of a system that enables the production of biodegradeable bioplastics from natural feedstocks such as cellulose or sugars. The system includes 3D printing filament production as well as direct extrusion of useful parts.  &lt;br /&gt;
&lt;br /&gt;
Four main aspects are involved in the Bioplastic Extruder System. First, a bioplastic reactor is used to make bioplastic from abundant biological feedstocks such as cellulose, sugar, or starch. Second - once the plastic is produced - or is available from the waste stream - it can be extruded with the Bioplastic Extruder to make 3D printing filament. Third, the 3D printing filament is then used directly in 3D printers to make useful objects. Fourth, other useful products can be made with the extruder: plastic lumber, which can be made from recycled plastic and sawdust. This could be a great way to recycle plastics into durable construction materials. Other useful profiles - such as tubing and glazing panels - can also be produced with the bioplastic extruder. Thus, the bioplastic extruder per se can be used for 2 main purposes: making 3D printing filament as an intermiediate feedstock for 3D printers - or extruding useful products directly.&lt;br /&gt;
&lt;br /&gt;
Fig. The bioplastic production system of the GVCS consists of bioplastic synthesis followed by extrusion to produce 3D printing filament, tubing, sheets, or plastic lumber. 3D printing filament can be used for 3D printing. Thermoplastic elastomers - or rubber - can also be printed.&lt;br /&gt;
&lt;br /&gt;
There are 3 types of bioplastics - those derived from: (1) petroleum and biodegradeable; (2) biomass and biodegradeable; and (3) biomass and non-biodegradeable. OSE is most interested in bio-based, biodegradeable bioplastics, as the feedstocks are most widely available and can be produced ecologically anywhere in the world. &lt;br /&gt;
&lt;br /&gt;
The OSE bioplastic system allows for local recycling such that the plastic never ends up in the landfill - but is either reused or recycled. By eliminating plastic waste and turning it into valuable products, wealth can be multiplied. Also, we can clean up the environment by reusing plastics - which can otherwise persist in the environment for 1000 years. Such recycling also reduces the need for petroleum - the typical feedstock of plastics.&lt;br /&gt;
&lt;br /&gt;
Bioplastics derived from biomass that are non-biodegradeable can be produced from petroleum substitutes. Petroleum can be replaced with charcoal. As such, any plastic typically derived from petroleum can also be produced from renewable, plant-derived charcoal. In the OSE system, plant matter is pelletized, then burned partially for space heating or process heat - with the byproduct being the important charcoal feedstock. If one is interested in replacing petroleum-derived chemicals - charcoal is first burned in a gasifier to produce CO and H2 - just as the gasifier fuels regular engines with CO and H2 - a combustible mixture. Instead of being burned in an engine as a renewable fuel, these molecules can combine under heat and pressure and an iron catalyst to produce long hydrocarbon chains and water. The long chains are alkanes - the typical long-chain molecules of -[CH2]- found in petroleum. This conversion process is known as Fischer-Tropsch synthesis, and is important from the abundance mindset - in that all products than now come from coal and petroleum can be made more ecologically - from plants. https://en.wikipedia.org/wiki/Fischer%E2%80%93Tropsch_process  &lt;br /&gt;
&lt;br /&gt;
Fig. The circular economy of OSE is based on wood - to make charcoal, paper, bioplastic, rubber, and fuel.&lt;br /&gt;
&lt;br /&gt;
Cellulose acetate is a bioplastic that is easily made from the most abundant organic polymer in the world - cellulose. It can be made readily from trees. Did you know that wood fibers can be converted to this bioplastic by reacting these fibers - with glacial acetic acid? The product is 3D&lt;br /&gt;
&lt;br /&gt;
printable.http://www.designforcraft.com/new-materials-for-3d-printing-cellulose-acetate/  You can make windows with it.http://nvlpubs.nist.gov/nistpubs/jres/19/jresv19n4p367_A1b.pdf  Instead of trees, one can use any source of cellulose - paper, cotton, straw, or other cellulose materials. &lt;br /&gt;
&lt;br /&gt;
Straw and wood are thus very important in the overall product ecology for making fuel pellets, insulation for the Seed Eco-Home (with borax), strawboard, charcoal, paper,  steel (charcoal with iron ore), and bioplastics.&lt;br /&gt;
&lt;br /&gt;
Polylactic Acid, or PLA, is the most popular bioplastic used in 3D printing. It can be derived from bacterial fermentation of sugar - and is thus an accessible technology within the GVCS.&lt;br /&gt;
&lt;br /&gt;
Polyhydroxyalkanoate (PHA) or polyhydroxybutyrate (PHB) bioplastic polyesters are considered the best candidates to replace the current petroleum-based plastics due to their durability in use and wide spectrum of properties. https://www.intechopen.com/books/biotechnology-of-biopolymers/conversion-of-biomass-into-bioplastics-and-their-potential-environmental-impacts  They are made by bacteria from sugar or starch at an efficiency of up to 80% of bacterial cell mass.https://www.intechopen.com/books/biotechnology-of-biopolymers/conversion-of-biomass-into-bioplastics-and-their-potential-environmental-impacts  Some PHAs are elastomers. Thus - it is realistic to include rubber production for tires - from sugar or starch - within the industrial ecology of the GVCS. Unlike latex resin from dandelion roots - which can be used to produce thermoset plastics - PHA rubber is thermoplastic, so it can be recycled easily. Both PHA rubber and dandelion root rubber can be grown anywhere - thus removing the strategic importance of tropical rubber tree plantations. It appears that PHA rubber is more viable from the decentralization perspective. Wood, broken with acid to simpler sugars - can also be used a feedstock for PHA - thus making PHA rubber production possible anywhere in the world. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4964529/   However, woody crop can compete with food crops - so we once again emphasize perennial polycultures as ways to produce food, fuel, and fiber. With perennials, it is also easier to use degraded lands, which can be regenerated back to fertility and health when annual crops are removed from the equation.&lt;br /&gt;
&lt;br /&gt;
In addition to sugar and cellulose, starch from common sources such as potatoes or corn can be polymerized readily in the kitchen. For example, mixing vinegar and glycerine with the starch makes a bioplastic.http://opensourceecology.org/wiki/Starch_Bioplastic   This is the easiest route  that can be used for 3D printing&lt;br /&gt;
&lt;br /&gt;
The bioplastic extruder has 2 main functions: one is to perform extrusions directly - or to produce intermediate 3D printer filament which is then used to 3D print final objects. For the latter, we are currently building upon two open source projects working on plastic extruders: the Lyman Filament Extruder,http://opensourceecology.org/wiki/Lyman_Filament_Extruder  and the Thunderhead Filament Extruder from Tech For Trade.http://opensourceecology.org/wiki/TechforTrade  These are simple versions of plastic extruders - which if scaled up and made more robust - can produce not only 3D printing filament, but larger extrusions.&lt;br /&gt;
&lt;br /&gt;
==3D Scanner==&lt;br /&gt;
&lt;br /&gt;
The 3D scanner allows for scanning of 3D objects to produce Computer Aided Design (CAD) models for reverse engineering. This is very useful - as we can take existing parts and digitize them for use as editable CAD models. A single camera can be used for photogrammetry, which is a computational technique for converting a set of pictures of an object taken from multiple angles into a 3D object.http://opensourceecology.org/wiki/Open_Source_Photogrammetry There is a number of open source programs that can do this. A 3D digital object can also be generated using multiple cameras, laser beams, or other light sources reflected from an object. As the simplest route, OSE  will build on existing work to develop the toolchain and procedure for photogrammetry - as that requires no hardware outside of a simple camera and a computer to process the images. If markers are used on objects, accurate CAD can be generated with proper dimensions. &lt;br /&gt;
&lt;br /&gt;
It gets more interesting: we can 3D scan internal features, too. This is known as industrial Computed Tomography (CAT) - essentially - a CAT scan for metal objects. By using an x-ray or gamma ray source - and then photographing an image - we can build a low-cost DIY CAT scanner.https://www.youtube.com/watch?time_continue=25&amp;amp;v=hF3V-GHiJ78  http://www.tricorderproject.org/blog/tag/openct/  Combined with an open source code base for image processing  from CERN, 3D industrial tomography scans can be obtained.https://home.cern/cern-people/updates/2016/09/new-open-source-medical-imaging-tools  &lt;br /&gt;
&lt;br /&gt;
==CNC Circuit Mill + Small Laser Cutter==&lt;br /&gt;
&lt;br /&gt;
We have already prototyped a circuit mill - the D3D CNC Circuit Mill.http://opensourceecology.org/wiki/D3D_CNC_Circuit_Mill  This shows a great example of the Unversal CNC axis modularity - where we have used the same motion system as in the 3D printer - but now strengthened the motion system by doubling the x axis to hold a small router. While the 3D printer is a non-contact manufacturing method - the circuit mill requires that the axes withstand contact forces of the milling operation. The strong, steel space frame of the D3D platform can handle these forces.&lt;br /&gt;
&lt;br /&gt;
Furthermore, other tool heads can be used on the Universal Axis. One useful example is a small 4W laser cutter, which cut up to ¼” plywood for prototyping purposes.&lt;br /&gt;
&lt;br /&gt;
Fig. The OSE CNC circuit mill and example circuits produced. The Router Tool Head is one of many tool heads that can be used on the Universal Axis system. A small laser is another, and can be retrofitted readily. The laser cutter toolhead allows for cutting cardboard for rapid prototyping. (4-picture - mill+product, laser+product)&lt;br /&gt;
&lt;br /&gt;
Prototyping with a laser cutter is important to the GVCS because the laser cutter can simulate the cutting that is typically done with a CNC torch table. Just like the CNC torch table typically cuts ½” thick flat parts out of sheet steel - the small laser cutter can cut parts out of paper stock. These parts can then be glued or fit together - just like the CNC-torch-cut metal parts are welded to make real-life 3D machines such as the CEB Press.&lt;br /&gt;
&lt;br /&gt;
Fig. Flat metal is used to generate 3D objects by welding. We thus use 2D cutting to create 3D objects.&lt;br /&gt;
&lt;br /&gt;
An open source project for a larger laser cutter - the 100W Lasersaur - is already well-developed. We can use this platform to build upon as well, to reduce cost from its current $7k to something more on the scale of $3k for a large format laser cutter. The Universal Axis could be applied here, such that only the laser system ($2000) remains as a significant cost - and the rest of the system is ($1000). This would be another great application of the Universal Axis to show its flexibility.&lt;br /&gt;
&lt;br /&gt;
Another useful example of a practical tool-head is a ceramic 3D printer head - which is an extruder for clay materials that can be fired to make functional ceramics. Examples of very useful ceramics are insulators and pottery - especially stovetop cookware made of flameware clay - which can replace commercial cookware and provide artistry in the open source Seed Eco-Home kitchen.&lt;br /&gt;
&lt;br /&gt;
Fig. The ceramic print head allows for the production of practical objects such as pots and pans for cooking, bringing artistry back into the kitchen.&lt;br /&gt;
&lt;br /&gt;
Collaborative Prototyping + Model Kits + Product Ideas + The Open Source Everything Store&lt;br /&gt;
&lt;br /&gt;
With access to the OSE Developer Kit - 3D printer, CNC Circuit Mill, and Laser Cutter - all as different tool heads on the same Universal Axis system - collaborators access a powerful capacity to prototype the larger machines of OSE. Using these tools, accurate scale models can be built. This can extend the collaboration capacity on OSE machine development significantly. There are 4 major ways that collaborative prototyping can be done using the 3-in-1 Universal Axis machine. &lt;br /&gt;
&lt;br /&gt;
First, there is collaboration is CAD verification. Computer Aided Design (CAD) is used in the OSE design process in order to save countless hours during the build. In a proper design process, it is easier to design in virtual CAD - and figure out how everything fits together - rather than going straight to a build and having to fit everything on the fly. The ability to model accurately in CAD is the power that allows OSE to do builds on the scale of a day - as opposed to weeks. However - this works only if the CAD is accurate, because if the CAD drafting is not accurate, it may be impossible to build a machine. CAD quality depends on the skill of the draftsperson. For this reason, it is important to verify the CAD as one of the steps that takes place prior to a build. If mistakes are not caught prior to the build, time and materials are wasted, people can get frustrated, and schedules are delayed.&lt;br /&gt;
&lt;br /&gt;
How do we guarantee that a machine can be built as drafted? With an accurate scale model. First, we must make sure that the CAD of individual parts is correct. This can be assured when accurate CAD files are available - whether the files are generated from measurements, provided by manufacturers, or 3D scanned with the open source 3D scanner. Second, we can verify the actual buildability. This can be done by laser cutting from paper the parts that would be CNC Cut from steel, and then 3D printing the components that we would otherwise get off-the-shelf. For the 3D printing - it is critical that we print every single part - up to bolts and nuts - so the entire assembly we can verify every single step of the build.&lt;br /&gt;
&lt;br /&gt;
This leads to the second use of collaborative prototyping - producing build instructional manuals and videos using the scale models. This allows contributors all over the world to produce meaningful content - without requiring that the contributors have access to a workshop. Since qulaity intstructionals production requires as much effort as the design work - this is another way to contribute to a large, parallel development effort.&lt;br /&gt;
&lt;br /&gt;
The third route to collaborative prototyping is the production of Model Kits for actual products. For example, the Seed Eco-Home lends itself very well for such modeling. Another company, Arckit (ref), is a good model for how we can design the model kit for the OSE’s collaboration with the Open Building Institute.&lt;br /&gt;
&lt;br /&gt;
Fig. Arckit is a great example for modeling. In the OBI case, the models correspond to real building panels and real build procedures. This makes the OBI Architecture Kit a tangible way for people to get involved in meaningful design of future house models.&lt;br /&gt;
&lt;br /&gt;
The OBI Architecture Kit lends itself well to 3D printing as well as laser cutting. 3D printed parts would snap together like Lego blocks.&lt;br /&gt;
&lt;br /&gt;
Another model kit that would be very useful to GVCS prototyping is the Machine Build Kit -  a kit for producing tractors, heavy equipment, and other automated machines. Combined with the OBI Arch Kit for buildings - this would produce the Civiliation Model Kit. The concept for the Machine Build Bit is a mixture of Lego Mindstorms, MakeBlock, Erector Set, Capsela, Box Beam Sourcebook, and Solar Micro Power Cube (all refs) - so that the system can run on solar power. The value proposition is that the kit would once again be based on real buildable parts - thus extending its use from childsplay to real design work.&lt;br /&gt;
&lt;br /&gt;
The OSE Developer Kit + Model Kits pave the way for the 4th route to collaborative prototyping - that of developing open source enterprise. These 2 kits are products in themselves - and can be used as the basis for collaborative business development of distributive enterprise (ref). The concept here revolves around reaching the $1T tipping point for the open source economy - the point at which mainstream adoption of open source economics is likely ($1T is calculated as the 10% tipping point at which viral adoption of open source economics can occur. This coincides with the next Enlightenment of humanity - see Tipping Point on the wiki - http://opensourceecology.org/wiki/The_Tipping_Point  ). This is as large as the combined revenue of Apple ($229B), Google ($79B), FB ($41B), Amazon ($178B), and Walmart ($486B) combined (Microsoft ($90B) - not includes so total is $1T.) - the latter being the single largest corporation in the world.&lt;br /&gt;
&lt;br /&gt;
OSE’s distributive enterprise approach to the tipping point is distributive. The core of OSE’s economic theory is that, by definition, a distributive enterprise serves its customers more effectively than any proprietary enterprise. Thus, a DE has a high likelihood of deposing the corporation http://opensourceecology.org/wiki/The_Corporation  as the dominant societal institution, replacing it with the next phase of the human economy - the open source economy. The transition is in our view likely - because the goal of a distributive enterprise is to produce free enterprise - defined as  distributing wealth most equitably. Current economic paradigms do not internalize distribution in their economic models. The next economy is achievable via full cost accounting and zero competitive waste, thereby achieving zero marginal cost (ref ZMCS). This proposition is simple to grasp, but most challenging to execute. We are not interested in DE as an ideology - but as a pragmatic proposition that simply meets needs more effectively - in an integrated sense -  than current models.&lt;br /&gt;
&lt;br /&gt;
The ask for distributive enterprise is to create the Open Source Everything Store - a networked and collaborative store based on Open Source Microfactories. That is - for people to collaborate on open source product development as a massive parallel effort. Decentralized, distributed, networked production is not a new idea - many people love and claim the idea as their own. To date no successful, economically-viable implementation exists, and certainly not open source. There were many attempts, from the FabLab, Local Motors, 1000 Garages, Ponoko - but none are both distributed and open source. The FabLab is a distributed microfactory concept, but none of its machines are currently open source. FabLabs are are externally funded, and none are used to run a successful business. Local Motors works on distributed production, but their designs and microfactory tools are not open source. 1000 Garages appears stalled. Ponoko and many operations like Ponoko are available. They are successful enterprises, but they do not use open source production tools or software. None of these projects provide open source enterprise information. Perhaps the best examples are 2: first, Lulzbot, which shares its machine designs and enterprise blueprints (blog post from 2014 visit, google Distributive Enterprise) - which makes it a fully open source hardware company - but it has a centralized business model. Second, there is the poster child RepRap project - which is the design/collaboration repository for open source 3D printers. RepRap is responsible for producing most of the consumer 3D printing industry’s companies - both open source and proprietary. (ref) However, RepRap in itself does not have a revenue model. Our own work is also based on the RepRap - it’s the basis that saved us hundreds of development hours - as we could simply build upon their designs. We do have a successfully-demonstrated revenue model of ongoing Extreme Manufacturing workshops.&lt;br /&gt;
&lt;br /&gt;
For The Open Source Everything Store (TOSES), any product developed must include open source blueprints, as well as open source enterprise documentation. Assets such as marketing materials, revenue models, business plans, projections, and entrepreneurship training - among others - must be included to facilitate startup by others. For successful startup - the enterprises themselves must be tested and proven. Thus, case studies of projections, actual revenue, and growth must be included. &lt;br /&gt;
&lt;br /&gt;
With as small an infrastructure as a Personal Microfactory with 3D printing, the CNC circuit mill, laser cutter, filament extruder, and off-shelf components - production of many valuable products can be distributed far and wide. Moreover, open design allows for extended product lifetime - as parts can be upgraded, modifications can be 3D printed, and breakages fixed with readily-accessible parts.  The success of TOSES  revolves around a massive parallel open source product development process - resulting in best-in-class products. These products are then produced by distributed players. Thus, a networked effort could reach substantial distributed production - and distributed sales volumes on the scale of Amazon. &lt;br /&gt;
&lt;br /&gt;
Our claim is that Distributive Enterprise has a good chance of succeeding because of its distributive nature. The cost structure of distributive development is efficient - as it relies on an open source process. We are assuming here that the zero marginal cost prediction - that everything trends to zero marginal cost - which is the competitive advantage of TOSES. However, zereo marginal cost is inherently impossible within the current system. The profit motive of the corporation prevents zero marginal cost, and leads to a permanent inefficiency in human economics. This can be resolved only by a transition away from the traditional corporate IPO form (ref). This is the reason why OSE proposes that a transition to the open source economy is inevitable. However, leading economic theorists such as George Gilder claim that human constructs are not inevitable - they have to be created. Thus, it remains up to human will to decide whether we would like to implement true-cost accounting to transition to the open source economy.&lt;br /&gt;
&lt;br /&gt;
The choice is up to us, and as such we are working on the DE model. Once open source product and enterprise blueprints are available - it means that everyone has access to them. This indicates that efficient production can be distributed into a networked form, which can gobble up Amazon and Walmart. Such a transition to the true-cost accounting economy is the promise of open source economics.&lt;br /&gt;
&lt;br /&gt;
In practice, this requires that open source microfactories, as well as open source materials production facilities - are distributed far and wide. These take abundant natural resources and convert them to a modern standard of living in a distributed way. People can produce with their personal microfactories. Using the 3D printer, circuit mill, laser cutter, and filament extruder - and off-shelf components - people can produce many household goods, electronic gadgets, toys, tools, kitchenware, small appliances, lab equipment (ref), and many others.  The size of the plastic industry alone is $2T - and the size of the injection molding industry is about $100B. Between vaccuum cleaners ($1B), consumer 3D printers ($1B),  cordless drills ($1B in the USA alone), drones, phones, cameras - the market size for those goods is on the order of hundreds of billions of dollars worldwide.  The current limit is 20% of GDP - the manufacturing sector of the economy - or about $16T.&lt;br /&gt;
&lt;br /&gt;
The centralized factory can become obsolete, and many parts of global resource flows can become localized. Specifically - as resource constraints to longer fuel resource conflicts and poverty - humans as a whole have - for the first time in world history - a chance for collective evolution. That simply means that the leading preoccupation transitions from making a living, surviving, or paying off debt - to thriving. This means that the multidisciplinary genius will become much more common - as society reaches a new level. An Einstein could be born every minute. (That makes it 1/250 - or 0.4% of the population.) This means that we transcend William Gibson’s — &#039;The future is already here – it&#039;s just not evenly distributed”. This means that most people will gain access to significant improvement in their quality of life. But this is also not a state of coerced equality as in communism - there will always be outliers who are more ambitious or skilled. But all have a good oportunity to thrive. &lt;br /&gt;
&lt;br /&gt;
CNC Torch and Larger Machines: Heavy Duty CNC Machining&lt;br /&gt;
&lt;br /&gt;
==CNC Torch Table==&lt;br /&gt;
&lt;br /&gt;
The universal axis can handle much larger forces - up to one thousand pounds - when it is scaled up. The universal axis has aleady been used with the 3D Printer and the CNC circuit mill. http://opensourceecology.org/wiki/Universal_CNC_Axis   &lt;br /&gt;
&lt;br /&gt;
We have already built a prototype of the CNC torch table using the Universal Axis, scaled up to a 2x3 meter working area:&lt;br /&gt;
&lt;br /&gt;
Fig: CNC Torch Table build workshop results. (https://www.facebook.com/marcin.jakubowski.378/posts/10213076897374250) &lt;br /&gt;
&lt;br /&gt;
The CNC Torch Table is near release status, and it will be the critical machine used in digital fabrication. The CNC Torch table will be used to cut all metal from flat sheets, which are then welded into 3D machines such as the brick press and tractor. The CNC Torch Table will also be used for cutting holes in 4” square tubing - which is our characteristic life-size erector set design.&lt;br /&gt;
&lt;br /&gt;
Typically, acetylene is used as a cutting gas. In the OSE case, the CNC torch table integrates with the oxyhydrogen production - where water is split into hydrogen and oxygen using electrolysis. These hydrogen and oxygen gases are used as the cutting gases. Oxyhydrogen cutting has been in use prior to the discovery of oxyacetylene cutting in 1903 https://en.wikipedia.org/wiki/Oxy-fuel_welding_and_cutting  - and was preferred for 2x the cutting speed with thick metal. Currently, oxyhydrogen is use whenever a clean cut is required. Otherwise, the gas is 2x as expensive as acetylene. The advantages of hydrogen are the ability to cut aluminum and stainless steel, which acetylene cannot do. Furthermore, if the open source oxyhydrogen generator is used with PV electricity at 1.5 cents per kWhr, then the cost of the gas should go down to about 5x lower than acetylene. Given these advantages, it is interesting to see that oxyhydrogen cutting is not used more commonly in the workshop. The apparent reason for this appears to be the lower price of fossil-fuel derived acetylene. Off-shelf on-demand oxyhydrogen generators appear to be expensive, so they would benefit greatly from being open-sourced. https://www.alibaba.com/product-detail/Gas-generation-equipment-for-oxgen-hydrogen_1950398042.html?spm=a2700.7724838.2017115.380.1b0840b43VI2AU  Hydrogen generators which can produce enough gas for cutting ½” steel are  are available for around $300, not including power supply. http://opensourceecology.org/wiki/Oxyhydrogen_Generator_Cost &lt;br /&gt;
&lt;br /&gt;
The OSE CNC torch table system includes a water bed to minimize smoke and prevent steel from warping while cutting, automatic height control which follows the surface of the metal for optimal cutting, an automatic ignitor, automatic gas control, open source controller, and open source controller software. Each of these piecces has been tested separately, and now we are putting the entire system together to a product that from 2018 onwards will be used to cut all steel for OSE in house. We cut steel for frames of the 3D printer, metal for the brick press, tractor, and just about every other GVCS tool.&lt;br /&gt;
&lt;br /&gt;
==Heavy Duty CNC Multimachine==&lt;br /&gt;
&lt;br /&gt;
The CNC Multimachine is a mill, drill, lathe and other tools in one machine, designed for modularity and flexibility, including rotary indexing and a grinding attachments. It can be used to produce engines and hydraulic motors, threaded parts such as bolts and pipe threads, as well as myriad other parts. The lathe has historically been the cornerstone of precision machining, and is a critical tool in civilization.  It is also another application of the OSE Universal Axis system - using the 2” rod size.&lt;br /&gt;
&lt;br /&gt;
Two other GVCS machines - the induction furnace which melts scrap metal to make virgin steel -  and the Mill which makes Rods and Wire - provide feedstocks for the CNC Multimachine.&lt;br /&gt;
&lt;br /&gt;
Fig. The 2” Universal axis can produce parts with accuracy of 10 microns, based on the deflection of 2” rods with 200 lb of force. This image shows the size comparison between the 2” version - and the 1” and 5/16” versions. The belt drive system can be identical to the smaller machines.&lt;br /&gt;
&lt;br /&gt;
We are interested in developing a core set of modules for a heavy duty machine - including mill, drill and lathe, with rotary and angle tables, plus capacity to function as a screw machine for making threads and bolts. We also include internal threads splines. &lt;br /&gt;
&lt;br /&gt;
Just like with the OBI Arch Kit (make sure reference is correct to rapid prototyping above), the Multimachine Construction Set will allow for modeling with 3D printed parts, which will correspond directly to real life - and thus serve as an educational kit and product. Together with the Multimachine Design Guide and FreeCAD workbench, people will be enabled to build their own multimachines and screw machines.&lt;br /&gt;
&lt;br /&gt;
For the 2” universal axis system, the practical limit is 400 lb of tool force with 0.001 precision and GT2 belt drive. For higher tooling forces, we must use lead screws instead of belts.&lt;br /&gt;
&lt;br /&gt;
The goal of the CNC multimachine is to produce electric motors, hydraulic motors, engines, cylinders, and valve blocks, among others. With a grinder attachment, the idea is to be able to achieve high precision, down to 0.0005, which is the positioning accuracy of the stepper motors at 16 microstepping and 1” GT2 pulleys.&lt;br /&gt;
&lt;br /&gt;
Using the Universal Axis, CNC linear motion control, and CNC rotary chuck control - we can get a wide array of functionality of a screw machine for making various precision parts. With a surface grinder, we can get precision parts down to 25 microns of tolerance. If we build a precision CNC surface grinder, then we can achieve up to 1 micron accuracy for making air bearings.https://www.youtube.com/watch?v=sFrVdoOhu1Q  Air bearings open the possibility of lubrication-free engines and high pressure pumps for storing hydrogen and a prerequisite for certain clean-room semiconductor manufacturing.&lt;br /&gt;
&lt;br /&gt;
==Robotic Arm - trainable for welding + 3D printing==&lt;br /&gt;
&lt;br /&gt;
The robotic arm is a powerful manufacturing tool as it is can move almost as flexibly as a human arm - but with increased precision and strength. Practical tasks that a robotic arm can accomplish depend on the end effector or tool that the arm is holding. For the GVCS, two good applications include automated welding and 3D metal printing using a MIG or TIG welder.&lt;br /&gt;
&lt;br /&gt;
Fig. Robotic welding - [nice pic] is useful for high quality welding to assist the open source renaissance woman. Spot welding or wire welding can be used.&lt;br /&gt;
&lt;br /&gt;
A useful application of robotic arms emerges from trainable robotic arms. Trainable robotic arms are arms which a human operator can train to move as needed. This eliminates complex programming tasks, making robotic collaborators accessible to the general public. An open source software platform already exists for robotic arms in the Robotic Operating System (ROS) project, including trainability.http://moveit.ros.org/  - such that the open source trainable industrial robot is around the corner by building on existing prior art. &lt;br /&gt;
&lt;br /&gt;
==Induction Furnace==&lt;br /&gt;
&lt;br /&gt;
An induction furnace is a device use to melt metal.  Metal can then be recycled - from scrap to useful stock. The advantage of the induction furnace over any other means of melting metal is a clean, energy-efficient and well-controllable melting process. In a typical induction furnace, a water-cooled copper coil with alternating current induces a current in a crucible of metal - hence the name Induction furnace - and that current heats up and melts the metal. Due to the heat being generated within the work piece, energy transfer is extremely efficient.&lt;br /&gt;
&lt;br /&gt;
Fig. In an induction furnace&lt;br /&gt;
&lt;br /&gt;
The induction furnace brings us from the stone and wood age - when stone and wood were the most common materials for making houses and machines - into the iron age - which is synonymous with the industrial age and modern civilization.  &lt;br /&gt;
&lt;br /&gt;
It may be said that modern civilization has culminated with the production of ball bearings. Bearings are a critical component that allows for engines, turbines of modern power to work - and precision machines that use precision ball bearings are used to manufacture these machine. Finally,  vacuum pumps and precision instruments - necessary in semiconductor manufacturing - depend on the use of bearings. As such, the information age today also relies on ball bearings - a combination of material science and precision manufacturing.&lt;br /&gt;
&lt;br /&gt;
==Metal Rolling, Rod &amp;amp; Wire Mill==&lt;br /&gt;
The induction furnace can be used in metal casting, where round rods or billets are cast and then used as feedstocks for metal rolling.&lt;br /&gt;
&lt;br /&gt;
Metal rolling uses rolling dies to shape metal into various profiles, from flat, to round, to angled. &lt;br /&gt;
&lt;br /&gt;
Fig. Metal rolling uses dies of various shapes to produce final stell shapes.&lt;br /&gt;
&lt;br /&gt;
Rolling of thin rounds - or rods - around dies and pulleys - is used to elongate and thin the rounds results in wire - a fundamental building block of civilization. Wire is used for house electrical wiring, suspension,  or fencing.&lt;br /&gt;
&lt;br /&gt;
Fig. A wire drawing machine starts from rod and stretches it to wire through a number of dies. The modular open source version can take rod and turn it into wire of any diameter.&lt;br /&gt;
&lt;br /&gt;
Metal rolling that occurs above the crystallization temperature (700C) is called hot rolling - and it takes less energy to do so as the metal is pliable. Cold rolling occurs at room temperature, and therefore requires more energy to deform the metal - but it also provides more accurate dimensions in the metal.&lt;br /&gt;
 &lt;br /&gt;
==Forging, Ironworker==&lt;br /&gt;
&lt;br /&gt;
The press forge is a heavy duty press than can be used to squeeze metal like butter. When metal is hot, it can be deformed into useful shapes by using a die. Bolt heads are made this way.&lt;br /&gt;
&lt;br /&gt;
Forges can take the form of press, drop, or roll rolling - preferably using the induction furnace for efficient forging. Cold forging may also be done, but that requires larger force for a given deformation.&lt;br /&gt;
&lt;br /&gt;
Forging is useful but the disadvantage is using specialized forming shapes or dies. Thus, the preferable route to forging would in many cases be subtractive machining, metal 3D printing,  or welding - as these are general-purpose procedures that do not require custom forms or dies.&lt;br /&gt;
&lt;br /&gt;
Fig. The press forge can shape hot or cold metal like butter.&lt;br /&gt;
&lt;br /&gt;
==Plasma Cutter, Welder==&lt;br /&gt;
&lt;br /&gt;
The plasma cutter, welder, and induction furnace are high-power electronics that use modern technology for efficiency. By using transistors and inverter circuits instead of large transformers, they can be light-weight and low cost - as the cost of power transistors is 10 cents/kW of power handling ability. This means that the simplest welder circuits can cost only a few dollars in electronic components (not counting wiring, structure, and the balance of system) to get industrial welders on the scale of 10kW (500Amps).&lt;br /&gt;
&lt;br /&gt;
Fig. Diagram of a welder. From first principles, a welder includes power handling electronics, wires, a case, cooling fan, and a welding gun with an electrode, and shielding gas for high quality welds.  In the simplest case - a tungsten electrode creates an arc to the metal and melts the metal, without using filler. This is an example of autogenous welding, where no welding rod or wire is required.  Welding is not complicated - the simplest electric arc welder is a 12V battery connected to a welding rod.&lt;br /&gt;
&lt;br /&gt;
A plasma cutter is a transistor-based power electronic device that cuts conductive metals with a plasma - or ionized gas.  The plasma cutter creates ionized air between an electrode and a work piece. The plasma heats the metal. By directing a focused stream of air around that plasma through a nozzle, the heated metal is oxidized and blown away, creating a clean cut. For comparison,  cut quality  in order of improvement is plasma cutting, oxy-fuel, waterjet, and laser cutting.&lt;br /&gt;
&lt;br /&gt;
Fig. Cut width - or kerf - of plasma, oxyfuel, waterjet, and laser cutting.&lt;br /&gt;
&lt;br /&gt;
Both the plasma cutter and welder are similar to each other. They have similar power electronic circuits.  For a welder or plasma cutter, the main difference is in the gun and electrodes. The gun in both cases has a large copper power wire and a gas line for shielding. For the MIG welder, it also has wire feed. The electrode is tungsten for the TIG welder and plasma cutter, and consumable welding wire for the MIG.&lt;br /&gt;
&lt;br /&gt;
More Power Electronics&lt;br /&gt;
&lt;br /&gt;
Is EDM practical? EDM is a high-voltage spark erosion system for cutting thick metals - where a moving wire at 10,000VDC spark-erodes metals as tiny sparks are established between the wire and metal to be cut. This system is insulated&lt;br /&gt;

Fig 1. The Tractor, Microtractor, Microcombine, Universal Seeder, Spader, Hay Cutter, Hay Rake, Baler, and Dairy Milker, and a Bakery Oven are critical tools of the $8T food industry.&lt;br /&gt;
&lt;br /&gt;
==Tractor, MicroTractor, Bulldozer and Power Cubes==&lt;br /&gt;
&lt;br /&gt;
The tractor is a cornerstone of a farm, construction, or other materials production industries. A tractor has the traction to pull things, and to do utility work with variou implements that can be added to a tractor and use the tractor’s mechanical power through a Power Take-off (PTO). As such, the tractor can be a swiss army knife of heavy duty work. For the smaller individual or home scale, we have the MicroTractor in the set, which is a small, walk-behind or ride-on tractor at the 16-32 hp size that can perform many gardening and utility functions and can fit in a smaller areas where a large tractor would be impractical. If we go up in scale - use a stronger frame and at least 64 hp, and add a bulldozer blade to the tractor - then we have a bulldozer.&lt;br /&gt;
&lt;br /&gt;
The tractor is a machine on the scale of 50-320 hp in the GVCS ecosystem, and unlike traditional tractors, we focus on modular power. We currently use small 16 hp engine units at $17/hp (ref), which is the lowest cost way to obtain engine power, while making maintenance very easy. Like in nature where a tree is made of many branches, our tractor is made of many small engine units. This way, the same design pattern can be used in the 16 hp tractor as in the 320 hp tractor. The price for using larger diesel engines is 2-4 times larger.  &amp;lt;ref&amp;gt;http://opensourceecology.org/wiki/Diesel_Engine_Cost &amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
By using the modularity concept, we create our typical construction set approach for heavy machines. For example, if a large tractor frame is fitted with a bulldozer blade - then we don’t require a separate bulldozer in addition to a tractor. This saves a lot of resources - making technology significantly lower cost to maintain. Exploring the limits of modularity, we found that it is much less expensive to scale our machines usig modular and overbuilt parts that make sense both for small and large machines. For example, we can use 4 of our identical track units, each rated for up to 80 hp - Our track unit, for example, allows for a $30k version &amp;lt;ref&amp;gt; http://opensourceecology.org/wiki/Modular_Track_Unit_v18.01&amp;lt;/ref&amp;gt; that matches the traction of a Cat D7 - a sizeable cost savings comprd to a base price of ½ a million. &amp;lt;ref&amp;gt;https://www.caranddriver.com/reviews/caterpillar-d7e-feature-test &amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Fig. Pattern Language for a Tractor - up to automated control.&lt;br /&gt;
&lt;br /&gt;
The key is making it easy and quick to interchange parts - from small parts to large implements. This is a great challenge for advanced industrial design.&lt;br /&gt;
&lt;br /&gt;
Fig. Industrial smaller parallel and trained configuration. OSE machines can be designed like this, but higher flexibility of the OSE platform can allow for an improved configuration.&lt;br /&gt;
&lt;br /&gt;
Fig. The flexibility of a modular OSE tractor. The modular OSE tractor can be built from the same components, but apply to 16 hp or 320 hp machines while using the same over-engineered components such as the ½” thick steel tracks &amp;lt;ref&amp;gt;Current design is rated for  rated for 40 hp per track or 80 hp with double drive, . (ref - do calculations) and 3600 lbs or 7200 of pull each. Thus, a four-tracked machine can have 29,000 lb of pulling force with direct drive using our current 15k in-lb motors.&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
==Spader, Seeder, Bulldozer==&lt;br /&gt;
&lt;br /&gt;
Your food today is grown largely by tractor-driven  tilling and seeding, unless you’re a breatharian. Tillage in the OSE system chooses the spader as a more progressive technology compared to the age-old plow. &lt;br /&gt;
&lt;br /&gt;
Fig. (Image of 1800 steam tractor with 50 bottom plow) &lt;br /&gt;
&lt;br /&gt;
The spader works essentially like  a bunch of shovels moving rapidly - which till soil without crating a hardpan typical of the more common plow. Manufacturers claim that spading uses 40% less fuel than plowing - because a spader can combine tilling, harrowing, and planting in one operation. &amp;lt;ref&amp;gt;https://www.farmax.info/PDF/Magazine-Farmax-EN.pdf &amp;lt;/ref&amp;gt; A plow, which drags through the soil, requires a lot of wheel-to-ground  traction, whereas a spader requires very little - thus avoiding soil compaction. It takes a spader under 9 minutes and 2 gallons of fuel per acre of field - such that feeding Dunbar Village &amp;lt;ref&amp;gt;A village of 200 -  based on Dunbar’s number https://en.wikipedia.org/wiki/Dunbar%27s_number &amp;lt;/ref&amp;gt; would take 6 hours to plant for a whole year of crop &amp;lt;ref&amp;gt;Assuming field crops planted with a seeder, not slips like sweet potatoes. http://opensourceecology.org/wiki/Acres_Needed_to_Feed_Dunbar_Village &amp;lt;/ref&amp;gt;Thus, one day to plant, two days to harvest - and the village has food for the year. &lt;br /&gt;
&lt;br /&gt;
The tractor and universal seeder is an example of how we approach multiple purpose machines. The tractor is a large-size swiss army knife for doing many different tasks. The Universal seeder is designed to plant all types of seed, from alfalfa to wheat, to tubers, and to live plants like sweet potato slips. Modifying the device rapidly is key to this flexibility.&lt;br /&gt;
&lt;br /&gt;
Fig. Swiss army knife tractor concept&lt;br /&gt;
&lt;br /&gt;
The point of using powerful machines wisely is that in the OSE perspective of lifetime growth -  life could become easy so we can focus on evolving as humans. Our experiment involves building a college campus where peole live this. When they graduate, they know how to organize a village to spend 2 hours per day working on survival, and then the rest of their life they pursue their highest ideals.&lt;br /&gt;
&lt;br /&gt;
The experimental village thus requires one farmer who is employed 3 days of the year, assuming the equipment does not break down, and generates 30 acres * $20k/acre of sweet potato, and $5k/acre for 10 acres of wheat if that is turned into bread  - or $650k worth of food for the community with direct marketing. That is $27k/hour if baking is automated - a decent pay, but not like the $25k/minute rate of Warren Buffett &amp;lt;ref&amp;gt;http://www.businessinsider.com/what-warren-buffett-makes-per-hour-2013-12  &amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Of course these are unreasonable figures, but they do represent the idea. The only way that customer acquisition and marketing costs do not ruin such ideals is in the case of direct marketing - where the on-site farmer-scientist provides for a captive audience of the Dunbar village. If each person eats about $2600 per year &amp;lt;ref&amp;gt;https://www.google.com/search?q=average+cost+of+food+per+year&amp;amp;oq=average+cost+of+food+per+year&amp;amp;aqs=chrome..69i57j0l5.7243j1j7&amp;amp;client=ubuntu&amp;amp;sourceid=chrome&amp;amp;ie=UTF-8&amp;lt;/ref&amp;gt;, feeding 150 people would involve revenues of $390k - but that would be a full time job. We will look more carefully at the business model for resident farmer agriculture in the Enterprise chapter.&lt;br /&gt;
&lt;br /&gt;
Now it would take more time to do a diversified operation, but this is shown just as a baseline to see what’s possible in terms of the effort.  Several Ph.D.’s can be granted to develop a diversified, 40 acre subscription farm, using open source equipment and a captive market, or Local Food Nodes as part of a distribution platform.  &amp;lt;ref&amp;gt;https://localfoodnodes.org/&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The OSE project will develop such a food enterprise both for its campuses and for the outside community - once all the farming machines are done, the aquaponic greenhouse production is optimized, and derivative food processing tools are developed.&lt;br /&gt;
&lt;br /&gt;
The open source tractor can be built at a cost of $125/hp at a scale of 80 hp, compared to $370-$1000 for other brands. It is useful to understand the basic cost breakdown based on off-the shelf parts:&lt;br /&gt;
&lt;br /&gt;
Fig. Cost breakdown of a tractor by Frame, engine, hydraulics, control, automation, and balance of system - $125/hp. (p590MJ)&lt;br /&gt;
&lt;br /&gt;
The cost advantage is less visible at the 32 hp MicroTrac, at $160 per hp - though but a comparable mahine like the tracked Toro Ding costs around  $1000/hp (ref).&lt;br /&gt;
&lt;br /&gt;
Fig. Microtrac with tooth bar bucket can till your garden, and provide valuable utility work. It is an indidspensible utility machine for any prosumer.&lt;br /&gt;
&lt;br /&gt;
==Hay Cutter, Rake, Baler==&lt;br /&gt;
&lt;br /&gt;
If farm animals are involved, then you need these. Or if you want to move large quantities of materials, then a bale is a useful form: from a bale of hay, brush, cotton, cardboard, or plastic - bales allow large scale moving of materials. Bales of aluminum cans are likewise useful for melting down in your induction furnace. If you are making fuel pellets from biomass, plastic pellets for making 3D printer filament - you will need a baler to make 1 ton bales.&lt;br /&gt;
&lt;br /&gt;
==Dairy Milker== &lt;br /&gt;
For animal husbandry, hay baling stores hay for the winter. Unless you are talking about the fish in your home aquaponic system. Dairy products themselves are $116B &amp;lt;ref&amp;gt;https://www.ibisworld.com/industry-trends/market-research-reports/manufacturing/food/dairy-product-production.html &amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
of the global economy - hence the relevance of the dairy milker. &lt;br /&gt;
&lt;br /&gt;
Table: values of the overall food, dairy, cattle, vegetable markets worldwide.&lt;br /&gt;
Combining the dairy milker with computer vision and automation, we envision a solar robotic milker - our MicroTrac with a milking stall - that drives up to a cow to milk her, and then brings the milk back for storage and processing. This allows field milking without human labor for small diversified robofarms that combine the best of regenerative agriculture with modern tehnology to relocalize farming.&lt;br /&gt;
&lt;br /&gt;
Fig. Robotic milker&lt;br /&gt;
==MicroTrac== &lt;br /&gt;
&lt;br /&gt;
A very interesting use arises with a small, solar, robot tractor - the MicroTrac driven by a solar panel. By adding a $10 Raspberry Pi Zero Controller &amp;lt;ref&amp;gt;https://www.adafruit.com/product/3400?gclid=EAIaIQobChMI2rz0mcnd2gIVCzlpCh3MpQgIEAQYAiABEgKi7_D_BwE&amp;lt;/ref&amp;gt; and a $100 solar panel you can be your robotic tractor - for agriculture and other. You can now mow your lawn automatically, and even pelletize it for fuel for a pellet stove. This is possible because today - advanced microelectronics such as the Raspberry Pi is 100 times faster that the first supercomputer, which cost $9M &amp;lt;ref&amp;gt;https://www.theregister.co.uk/2008/01/05/tob_cray1/ &amp;lt;/ref&amp;gt; in 1975.&lt;br /&gt;
&lt;br /&gt;
Fig. A solar-driven MicroTrac concept with solar panel and $50 arduino controller can provide autonomous agriculture &lt;br /&gt;
&lt;br /&gt;
==Bulldozer==&lt;br /&gt;
&lt;br /&gt;
Now add a bulldozer blade to a beefed up, tracked tractor - and you have one of the most powerful devices for regeneration - or destruction - depending on how you use the machine. Bulldozers are powerful earth moving machines - to build roads, grade house foundations, and in agriculture - to build regenerative earthworks for water and erosion. The biggest example is the 12,000 square miles that have been regreened in China - the Loess Plateau. &amp;lt;ref&amp;gt;John Liu reported on this - http://www.aquinta.org/news/2016/10/6/greening-the-desert  &amp;lt;/ref&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Fig.&#039;&#039;&#039; Loess Plateau reforestation&lt;br /&gt;
&lt;br /&gt;
So, if you ever drove on a road - you used a bulldozer. Maybe not you, but whoever graded the road base. &lt;br /&gt;
&lt;br /&gt;
==Microcombine==&lt;br /&gt;
&lt;br /&gt;
The Microombine is used to harvest grains and seeds of any type. This is the core of human harvests world wide. For the OSE case, we have a much more flexible and modular machine in mind. Based on our module-based aproach, we can use the same drive platform as the tractor&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Fig&#039;&#039;&#039;. Showing the base drive platform that can be used &lt;br /&gt;
&lt;br /&gt;
==Bakery Oven==&lt;br /&gt;
&lt;br /&gt;
Humble bread is a $419B global market https://www.ibisworld.com/industry-trends/global-industry-reports/manufacturing/bakery-goods-manufacturing.html . It is the 12th most popular food in the world. https://www.farmflavor.com/at-home/what-is-the-most-popular-food-in-the-world/  And 49% of Americans eat bread  https://www.smithsonianmag.com/smart-news/each-day-50-percent-america-eats-sandwich-180952972/ . &lt;br /&gt;
&lt;br /&gt;
Now bulldozers, tractors, and combines are all good - but the next step for gobal agriculture is the transition to  perennial polyculture  https://www.youtube.com/watch?v=KpJR2yfLUU0  , with only a small fraction of tillage ramaining.&lt;br /&gt;
&lt;br /&gt;
=Construction - 13 Tools=&lt;br /&gt;
If you want to build a charter city or a smaller campus, you will need construction equipment - and a trencher to put in gigabit internet fiber between the locations.&lt;br /&gt;
&lt;br /&gt;
The tools in the construction part outside of the tractors include the backhoe, trencher, cement mixer, sawmill, CEB press, well-drilling rig, soil pulverizer, hammermill. The universal rotor is a tool used in other sectors of the GVCS - and the SeedHouse is a living machine. &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Fig. 13 tools of the construction part of the Global Village Construction Set.&lt;br /&gt;
&lt;br /&gt;
==Backhoe, Trencher, Cement Mixer==&lt;br /&gt;
&lt;br /&gt;
The backhoe or excavator can be used to dig aquaponic ponds, foundation trenches. It can be used to remove stumps, do trenching, and with a grapple it can be used to lift logs or to hoist heavy objects. Backhoes are relatively simple devices - a set of pivot joints that use hydraulic cylinders for their motion - producing thousands of pounds of digging force at the touch of control levers. There are both side-to-side moving backhoes, but a 360 degree rotating backhoe is much more flexible. The small side to side version can be used on a front quick attach of a tractor.&lt;br /&gt;
&lt;br /&gt;
Fig. OSE backhoe from 2010 https://www.google.com/search?q=ose+backhoe&amp;amp;client=ubuntu&amp;amp;hs=ToH&amp;amp;source=lnms&amp;amp;tbm=isch&amp;amp;sa=X&amp;amp;ved=0ahUKEwjLzZKelOLYAhULbawKHQo-DVwQ_AUICigB&amp;amp;biw=1351&amp;amp;bih=731#imgrc=t8j52U9--mn6BM:  mounted on he original lifetrac, a small one used for water line trenching in 2012 http://opensourceecology.org/wiki/File:Bhp1.jpg , and a larger one from 2013 https://www.youtube.com/playlist?list=PL6Jpysxw3Ty-oH4bggp32PR_rPWr8bKC1 . Next iteration is the 360 degree backhoe with remote control drive to facilitate hydraulic line routing.&lt;br /&gt;
&lt;br /&gt;
The trencher in the original GVCS icon is a wheel trencher. We built 2 prototypes, and the next iteration will be a chain-based trencher based on our favorable experience with oversized chain drive on the bulldozer tracks.&lt;br /&gt;
&lt;br /&gt;
Fig. OSE Trencher http://opensourceecology.org/wiki/Trencher - 2011 and 2013 builds.&lt;br /&gt;
The cement mixer is indispensable. Cement has been used in ancient Rome and in mesoamerican temples. Scotland&#039;s County Cork had 23,000 lime kilns at one time - had one kiln per 80 acres. Wood or coal was used as fuel. http://www.lowtechmagazine.com/2013/09/lime-kilns.html  http://www.chapelgatehome.uk/our-blog   Portland cement took over lime cement in the last 100 years, but lime concrete is favorable in foundations becaue it doesn’t crack as easily as Portland. Using modern appropriate technology, lime cement production in solar microfactories is a viable enterprise at the 1 ton per day scale using an open source microkiln the size of a refrigerator. Limestone goes in one end, and lime comes out the other. With such small appliances costing around $1k, cement production can be distributed - while making cement production carbon neutral, annihilating  the current 5% CO2 emission share of the the concrete industry.https://en.wikipedia.org/wiki/Environmental_impact_of_concrete  This is possible in about 50% of America, where the bedrock is made of limestone. That’s a $10B industry in the USA alone.https://en.wikipedia.org/wiki/Cement_industry_in_the_United_States &lt;br /&gt;
&lt;br /&gt;
The cement fryer - a rotary lime kiln - is much like the cement mixer: a Universal Rotor with a heating element. A rotating pipe heated by PV, and an Arduino microcontroller to measure temperatures and guide the process to efficient completion. While not part of the 50 GVCS technologies, it’s a ready derivative:&lt;br /&gt;
&lt;br /&gt;
Fig. PV of the Open Source Materials Production Facility, a solar Power Cube, a Universal Rotor, metal pipe and an Arduino microcontroller constitute the lime cement maker.&lt;br /&gt;
&lt;br /&gt;
If we want to go to the essence of construction, take the backhoe excavator, chase it with a bulldozer with ripper shanks, and then rock under a site could be extracted to build a pond. This rock, if limestone, is feedstock for your lime kiln. In some places, rock outcroppings make access to limestone easy.&lt;br /&gt;
&lt;br /&gt;
==CEB Press , Soil Pulverizer, and Sawmill==&lt;br /&gt;
&lt;br /&gt;
The Compressed Earth Brick press and sawmill are critical tools for construction in that they produce materials. The CEB Press allows one operator to load raw dirt right from the building site to produce about 5000 bricks in a day - enough for a small house. &lt;br /&gt;
&lt;br /&gt;
Fig. The CEB Press is the first machine that we have prototyped, and it is ready for widespread replication around the world.&lt;br /&gt;
&lt;br /&gt;
We have used the soil pulverizer to prepare soil for pressing CEB blocks. The soil pulverizer was used to both pulverize the soil, and its bucket was used to press bricks for CEB construction.&lt;br /&gt;
&lt;br /&gt;
Fig. Soil pulverizer - Aidan on the tractor + loading the brick press by Yoonseo&lt;br /&gt;
&lt;br /&gt;
Our next step on the CEB press is a full soil conditioner which pulverizes soi, adds cement at a measured quantity of 5%, and then loads the mixture into the CEB press - to allow for production of high quality, stabilized block.&lt;br /&gt;
&lt;br /&gt;
Fig. The soil conditioner accepts raw soil from a tractor loader, mixes a measured amount of cement, and loads the prepared mixture into the CEB press for effective production of stabilized block at 12 cents ( 10 cent cement cost for a 20 lb block, and 2 cents gasoline cost). per block in materials. This means that we can build a 1’ thick CEB wall section for $50 in materials.&lt;br /&gt;
&lt;br /&gt;
The sawmill is a machine that can produce dimensional lumber - a staple of construction. Our sawmill is a variety known as a swing-blade sawmill, which has a single blade that can rotate 90 degrees and make a dimensional piece of lumber by going forward and back on a piece of wood.  We chose the dimensional sawmill for its simplicity over a bandsaw mill, as blade sharpening is much easier - and maintenance is the larger cost of any equipment if that equipment is designed for a lifetime.&lt;br /&gt;
&lt;br /&gt;
The sawmill is a good example of how we can use GVCS product ecologies to reduce complexity and reduce the cost of equipment. We design not just individual machines, but machine ecosystems that feed off one another. We can obtain drastic cost reduction by borrowing existing modules from the GVCS. For our case, it makes sense to design the sawmill as a Bobcat standard quick attach implement. We borrow the tractor as a  quick attach point, so that we do not need a bed upon which the sawmill head would otherwise ride. We borrow 32 hp from the tractor Power Cubes. We also  borrow the hydraulic motor which we attach with hydraulic quick-connect hoses. Thus, we have essentially stripped down the entire sawmill to the long carriage with the cutting head - saving $2k https://www.ebay.com/itm/30hp-Kohler-Engine-1-1-8-D-Command-15Amp-Exmark-CH750-0026/132423001888?epid=26011371639&amp;amp;hash=item1ed506a720:g:4YUAAOSwH2VaS3-h  on the engine, $2k https://sleequipment.com/dovetail-utility-trailer-7x20-with-3500lb-axles.html?fee=8&amp;amp;fep=524834&amp;amp;gclid=EAIaIQobChMIws349azn2AIVBqxpCh1rMwbpEAQYASABEgIeHPD_BwE  on a trailer. The greatest advantage would be the setup time - if designed as a quick attach implement, the sawmill can be taken to a log, rested right by the log, and ready for action - as compared to systems where the carriage base must be set up or the log moved into cutting position. If the sawmill can straddle right over a log or be raised with the loader arms, there is no limit ot the side of log that the mill can handle. &lt;br /&gt;
&lt;br /&gt;
Fig. The simplicity of the OSE swing-blade sawmill involves a long linear track mounted as an implement for the tractor. To provide 3 axes of motion - the loader mounting includes height adjustment (z motion), and a lightweight cantilevered head provides side-to-side motion. The cost of about $1500 is significantly lower than the $15k http://www.dltimbertech.com/dl-180-swing-blade-sawmill-10-x-20.html   minimum for a comparable 32 hp sawmill. (ref)&lt;br /&gt;
&lt;br /&gt;
And the sawdust that we generate can be used as animal bedding, insulation, or it can be pelletized to make fuel pellets.&lt;br /&gt;
&lt;br /&gt;
==Universal Rotor==&lt;br /&gt;
&lt;br /&gt;
The Universal Rotor is a fundamental building block for just about any moving machine. It is a combination of rotary motion and a useful tool-head. As a design pattern consisting of a shaft, bearings, and a motor -  a wide array of working tools can be attached to it - so that the Universal Rotor can constitute a drill, a wind turbine,  a wheel, a hammermill, cement mixer, sawmill - etc  - essentially any machine at any size - from small cordless electric drills to a larger 50kW rotor of a wind turbine. &lt;br /&gt;
The Pelletizer , Chipper/Hammermill, Dimensional Sawmill, Rototiler/Soil Pulverizer, Cement Mixer, Well-Drilling Rig, 50 kW Wind Turbine, Microcombine Thresher, and Bioplastic Extruder are direct applications of the universal rotor, and combined with precision machining structures, the Universal Rotor also include the heavy duty CNC Multimhttps://www.opensourceecology.org/portfolio/pelletizer/achine with lathe, drill press, slow cutoff saw, surface grinder, and other machines of fabrication.&lt;br /&gt;
If we can build a Universal Rotor, a Power Cube, and weld together  a supporting structure - then we have - broadly speaking - build 23 of the 50 machines of the GVCS. For example, if we consider the electric motor - it is a a shaft, 2 bearings, a structure, and the ‘tool head’ could be considered the electrical windings that make the shaft spin. Or, if we consider the metal lathe - a part of the Multimachine - then it is clear that the lathe consistr faksdjdfjks of a heavy shaft, 2 heavy bearings, and the tool-head is a chuck for holding work-pieces.&lt;br /&gt;
&lt;br /&gt;
==12. Well-Drilling Rig and Chipper/Hammermill==&lt;br /&gt;
The well-drilling rig is a machine used to dig deep water wells. It consists of a universal rotor which uses 3” (https://www.aquascience.net/grundfos-10sq05-160-230v-10gpm-1-2hp-230v-2-wire-96160140-3-stainless-steel-submersible-well-pump?gclid=EAIaIQobChMIlt-S3PDn2AIVC6tpCh369g34EAQYASABEgJr__D_BwE. 10’ of this pipe store 4 or 6.5 gallons of water. ) or 4” drill pipe to drill down to a depth of 100m or more using hydraulic rotary drilling. In this method, a stream of water is sent down the pipe during the drilling operation to send up tailings and soften the area of the drill point. A heavy duty hydraulic motor spins the drill rod - and new sections of drill rod are attached one after another. When the operation is done, the drill pipe is left underground and a submersible pump is inserted to pump water from the well.&lt;br /&gt;
Fig. A hydraulic deep well pump drilling system explained. The water swivel is the key part here. Otherwise 3” pipe that an be used as  drill pipe and casign is $12/foot. https://www.discountsteel.com/items/Galvanized_Steel_Pipe.cfm?item_id=172&amp;amp;size_no=11#skus  &lt;br /&gt;
The chipper/hammermill is another application of a universal heavy rotor with swinging or fixed blades. This machine shreds or pulverizes materials, and can be as small or large as needed.&lt;br /&gt;
Fig. Hammermill variations with various blades to chip wood or crush rock. A modified version of a heavy rotor can be a grinder. The scale can be from the largest - shredding cars - to the smallest - with small electric motors - if you have hydraulic drive and electric drive.&lt;br /&gt;
&lt;br /&gt;
==The House - Seed Eco-Home and Aquaponic Greenhouse==&lt;br /&gt;
&lt;br /&gt;
The Seed Eco-Home is a living machine - and becase it is the single largest cost of living today, we dediced to include that in the GVCS. (Initially, the house was not in the GVCS - but it was added as the Microhouse.) The  The Seed Eco-Home is the culmination of all the construction machines put to use. Homes are  also about  $3T (https://en.wikipedia.org/wiki/Construction#Industry_characteristics - residential construction is about ⅓ of all construction) market worldwide - which if open-sourced, could provide 30 million regenerative housing jobs for open source home building entrepreneurs Earning $100k each per year. This is 30 million potential collaborators - through we need only about 1000 at this time.&lt;br /&gt;
&lt;br /&gt;
The OSE/OBI https://www.openbuildinginstitute.org/  Seed Eco-Home is a an affordable, expandable eco-home that can be built for ⅓ the cost of a typical home, while including ecological features. Rather than building a large house, we propose starting with a seed home, and then growing it as the need arises. &lt;br /&gt;
&lt;br /&gt;
We are pushing ecological limits in our autonomous house design. The house is  off-grid with PV, provides its own cooking fuel from a biodigester, includes roof-top rainwater collection, and grows its own food with an aquaponic greenhouse. Mowed lawn or biomass is used to provide heating biomass pellets for a hydronic stove that is fueled by pellets. The eventual product vision is a house that  produces fuel for cars as compressed biogas or compressed hydrogen - by splitting water. Thus, we are correcting the oil and gas industry with 100% renewable energy, using simple, proven technologies. We are not relying on advancements in battery technology as a prerequisite to sustainable transportation, and by not requiring scarce lithium for batteries, we are aiming for an abundant and environmentally friendly energy future. http://www.kitco.com/ind/Albrecht/2014-12-16-How-Green-is-Lithium.html  We favor rooftop PV plus electrolysis as the preferred route for transportation fuels, where every house becomes a gas station. Using medium pressure electrolyzers that can produce hydrogen up to 33 atmospheres without needing a compressor - we can readily store hydrogen in large propane tanks or higher pressure steel pipe. &lt;br /&gt;

&lt;br /&gt;
Fig. Aquaponic greenhouse glamour shot.&lt;br /&gt;
&lt;br /&gt;
The aquaponic greenhouse is designed to provide a year-round supply of fresh eggs, vegetables, fish, and mushrooms. The goal is to include automated planting with a small Farmbot (https://farm.bot/ . By Shuttleworth Fellow friend Rory Aaronson.), where the resulting deep pots are planted in the  towers. With a 1000 plant growing capacity in the main towers, the greenhouse can provide a robust salad daily, where we plant and harvest 15 plants per day from a small 800 sf greenhouse. A mushroom yield of 1lb is obtained per week from a tower that takes only 1 square foot. We also intend to use automated 3D printed aerial drones for planting seeds directly into towers - a great example of useful product ecology. Local food addresses the issue of food miles, where food travels an average of 1500 miles in the USA before ending up on someone’s plate. https://cuesa.org/learn/how-far-does-your-food-travel-get-your-plate  This is one of the numerous inefficiencies that will be addressed by a more efficient, open source economy. This brings us to transportation.&lt;br /&gt;
&lt;br /&gt;
=Transportation. =&lt;br /&gt;
&lt;br /&gt;
The microcar, truck, electric motor, and hydraulic motor are the 4 GVCS machines directly related to transportation. &lt;br /&gt;
&lt;br /&gt;
The worldwide production of cars is a total of 95M per year, 75% of which is done by the top 15 companies. https://en.wikipedia.org/wiki/Automotive_industry#World_motor_vehicle_production  This lends itself to massive distribution of power. The OSE paradigm proposes instead that there would be on the order of million distributed enterprises - essentially one per 10,000 people. Each facility would produce cars on the scale of dozens or hundreds in the community-supported manufacturing (CSM) scenario. Thus, car producers replace car dealership  - as the producer takes to dealing.  This would go well with a gas station at every home, splitting Seed Eo-Home rooftop water for fuel at a cost of 80 cent per gallon of gasoline equivalent. http://opensourceecology.org/wiki/Hydrogen_Production &lt;br /&gt;
&lt;br /&gt;
Fig. Seed Eco-Home to car fuel infrastructure consists of rooftop water collection, 10kW of PV panels, a storage tank for hydrogen, and compression to 200 bar. Piece of cake if you consider not doing this - wars for oil. This gives us about 100 miles of fuel worth per day in a 100mpg microcar.&lt;br /&gt;
&lt;br /&gt;
==OSE Microcar==&lt;br /&gt;
&lt;br /&gt;
The OSE Microar is a Hydrogen Hybrid Hydraulic (H3) vehicle. Hydrogen is chosen because an internal combustion (ICE) engine running on hydrogen is twice as efficient (40%) as a normal ICE (20%), and only 25% under the 50% efficiency of fuel cells. http://environment.yale.edu/gillingham/hydrogenICE.pdf A hydraulic drive train (71% efficiency) - has a higher efficiency than a continuously variable transmission (60%) for fuel cell electric vehicles - meaning that the humble hydrogen hydraulic car gets a higher mileage than a fuel cell car, at significantly lower cost. At a design weight of only 850 lb, less than ¼ of a typical car, the OSE microcar focuses on moving the passenger, not a large chunk of metal accessory to the core purpose. Lighter cars have a good safety record. Before the S.U.V. boom, the country (USA) had the world&#039;s lowest highway death rate.http://www.nytimes.com/2004/05/05/business/averag e-us-car-is-tipping-scales-at-4000-pounds.html  Additionally, gas mileage for the OSE Microcar is specified for 100mpg. While not as testicular as a Tesla, the OSE specification requires higher self-esteem on the part of the driver to accept acceleration from 0-60 of 12 seconds, as opposed to under 3 seconds for a Tesla Model S.https://en.wikipedia.org/wiki/List_of_fastest_production_cars_by_acceleration&lt;br /&gt;
&lt;br /&gt;
Fig. The OSE Microcar concept.&lt;br /&gt;
&lt;br /&gt;
Can smaller cars are safer? This is controversial. https://www.ptua.org.au/myths/smallcar/  Physics says that energy of motion is proportional to v squared, and data shows that 56% of car deaths are single-car collisions. So unless you are going to hit another oncoming car or an immovable object like a large tree, your tiny car of under 1000 lb  has 36x less energy to dissipate than a Chevy Suburban of 6000 lb. And, the lightest car - the Smart Carfortwo at 1800 lb http://driving.ca/hyundai/accent/auto-news/news/these-are-the-ten-lightest-cars-you-can-buy-in-2015  and it certainly does get eaten up in a frontal 2 car collision with a larger car. And crashes took more than 37k lives in the US http://www.iihs.org/iihs/topics/t/general-statistics/fatalityfacts/state-by-state-overview#Crash-types  , with 20-50x more if injuries are counted. http://asirt.org/initiatives/informing-road-users/road-safety-facts/road-crash-statistics (are injuries better or worse in large cars?)&lt;br /&gt;
&lt;br /&gt;
But this is all before self-driving cars enter the scene - which have been tested for 0 driverless car crashes over 1.8 million miles by Google - with 13 fender benders caused by other cars. http://bigthink.com/ideafeed/googles-self-driving-car-is-ridiculously-safe  In other words, the case is there for super-small, super-efficient cars that are robotically controlled. &lt;br /&gt;
&lt;br /&gt;
What we have in mind follows the standard of the 200 mpg fuel efficiency of the VW  L1 first prototype car, at 640 lb weight, 8 hp, top speed of 75 mph, with tandem seating for 2. https://en.wikipedia.org/wiki/Volkswagen_1-litre_car. The efficiency dropped to 170 mph in a hybrid version - http://gas2.org/2009/09/14/volkswagens-diesel-hybrid-1l-concept-gets-170-mpg-available-by-2013/  If OSE achieves the same with 16 hp instead of 8 hp, and using hydraulics while not needing to go to a hybrid drive-train that apparently reduced its initial mileage performance - then we will have a major victory for open source-  Hydraulic accumulators may be used for peak power.  Plus, we’d like to achieve this with hydrogen as fuel in later versions.&lt;br /&gt;
&lt;br /&gt;
More specifically - our model is an H3E car - including a hybrid electric component.  The hydraulic component is a peak power electric-hydraulic micro-Power Cube of about 40 lb additional weight - powered by the onboard starter battery for its cranking amps.  This additional 30 seconds of a starter battery would double the power of the 16 hp engine - such that burst of energy for passing and sudden acceleration can be achieved easily.&lt;br /&gt;
&lt;br /&gt;
==B The Solar Car==&lt;br /&gt;
&lt;br /&gt;
The Solar Challenge is a fascinating event that shows PV-covered cars traveling 62 mph average across Australia. Granted that the driving is in expensive prototypes ad a sunny country - only in daytime - this still bodes well for the feasibility of solar transportation. The typical cars used are small - surface area of a Toyota Prius - and the OSE version would be twice as large 24x8 feet for 3kW of installed PV + 44 lb Lithium ion batteries + 2.5 kW small engine. http://opensourceecology.org/wiki/Solar_Car This allows for a total of 7kW of continuous power for one hour, or 4 kW total power continuous - at 750 lbs of weight. This just may work - if we 3D print a form frame for carbon fiber layup. 3D printing here may be the enabling technology.&lt;br /&gt;
&lt;br /&gt;
==Truck==&lt;br /&gt;
&lt;br /&gt;
The truck is a medium-size, hydraulic, 80 hp driven vehicle comparable to the Mercedes Unimog. https://en.wikipedia.org/wiki/Unimog  With a design top speed of 62 mph,  a weight of 6550 lb, and a hydraulic power take-off, the OSEmog could function as an agricultural tractor as well. The OSEmog is designed to accept a loader or various implements on the front or back. Using basic hydraulic circuits, the machine would have high and low gear, and speed cotrol via simple flow control valves.&lt;br /&gt;
&lt;br /&gt;
Fig. The OSEmog is a multipurpose truck for carryng loads or operating various implements. With off-the shelf parts, it is designed to be field serviceable, and the working hydraulic fluid can be grown - canola oil with additives.&lt;br /&gt;
&lt;br /&gt;
==Hydraulic and Electric Motors==&lt;br /&gt;
&lt;br /&gt;
Both the car have a choice of using hydraulic or electric drive. The advantages of hydraulics are low-cost, high torque, and simplicity of resulting drive design. Hydraulic motors cost only $10/hp, half that of electric motors - but a typical 40 hp hydraulic motor weighs about 50 lb http://opensourceecology.org/wiki/45.6_Cu_In_Hydraulic_Motor as opposed to about 350 lb https://inverterdrive.com/group/Motors-AC/TECA2-200L-4-Pole-B3-High-Efficiency-AC-Motor-200/ .  Typically electric motors are high speed and need to be geared down - whereas hydraulics can be used largely with direct drive. If high torque electric motors are used - these are more like $100/hp when the controller is included - making the drive system 10x as expensive for larger machines.  Electric motors are sensitive to moisture and dirt, while hydraulics are designed for dirty environments. &lt;br /&gt;
&lt;br /&gt;
We electric motors and generators - in solar electric power cubes - or in wind turbines. But the flexibility, power, and simplicity of hydraulics is a better choice for practical applications - especially when powered by hydrogen and transmitted by canola oil as the hydraulic fluid.&lt;br /&gt;
&lt;br /&gt;
The electric motor can also be 3D printed, making it fit with the OSE product ecology. &lt;br /&gt;
&lt;br /&gt;
Fig. A proprietary, 3D printed, 600W, 80% efficient electric motor. The equivalent is worthwhile to open-source.&lt;br /&gt;
&lt;br /&gt;
Electric motors can be both linear and rotary. In the linear form, they are known as solenoids - very useful devices that are used to make valves. For automation - we use dydraulic valves to control machines like the brick press - and solenoids are used wherever pneumatic or hydraulic controls are needed. This means any automated system - from the water control in aquaponics to the control of an industrial robot.&lt;br /&gt;
&lt;br /&gt;
The electric motor of interest ranges from a small 5W one to power a cordless drill - to the 50kW scale for use in the 50kW wind turbine.&lt;br /&gt;
&lt;br /&gt;
This brings us to the energy sector.&lt;br /&gt;
&lt;br /&gt;
=Energy Tools=&lt;br /&gt;
&lt;br /&gt;
The sun currently shines 10000 times more power to the earth than the entire civilization uses. The implications are profound: there is no such thing as an energy shortage. Energy scarcity is an imagined problem if we talk about actual availability of energy.&lt;br /&gt;
&lt;br /&gt;
We look at it as- it is a high priority to trap solar energy directly - by effective solar design of buildings (Homes and businesses spend about 50% of their energy on heating and cooling. )- and using photovoltaic energy (Solar Concentrator) to generate electricity locally, with wind (50kW Wind Turbine) wherever possible. For machines, the choice is to use hydrogen, charcoal, and compressed biogas. &lt;br /&gt;
&lt;br /&gt;
Hydrogen is by far the most efficient and clean when derived from water (as opposed to refining from oil and gas).  The process gives 0 pollution, and the product of hydrogen combustion is water. The OSE platform calls for provent internal combustion engines running on hydrogen as an immediately executable transition to a renewable energy future in transportation. Leading research institutes, such as the Rocky Mountain Institute (ref), promotes the hydrogen economy as the future, and hydrogen as a future energy source is not controversial if one assumes abundance of fuel feedstocks and distribution of energy production. Solar hydrogen can be produced anywhere, and wind hydrogen can be produced in most places around the world. We do not put such a high stake into batteries or supercapacitors when it comes to energy for cars, simply because chemical fuels are up to 140 times as energy dense. A typical energy density chart typically has chemical fuels off-the-charts good:&lt;br /&gt;
&lt;br /&gt;
Fig. Show specific energy density of storage media, with bats and caps, and chemical fuels, for perspective - https://en.wikipedia.org/wiki/Supercapacitor#/media/File:Supercapacitors-vs-batteries-chart.png. With supercapacitors having 100x less energy storage per weight than Lithium-Ion batteries, while costing 10x as much as ($2.85/kJ) as those batteries ($0.8/kJ), they are super-completely out of the question with today’s technology except for niche applications. Engines are .5kW/kg https://en.wikipedia.org/wiki/Power-to-weight_ratio#Engines  and Fuel (gas, diesel, methane) is 50MJ/kg and hydrogen is 140MJ/kg - or 50-140x more energy per weight than batteries. Given the environmental challenges of mining and recycling scarce metals, there is little case for battery-powered cars.&lt;br /&gt;
&lt;br /&gt;
That means that a non-battery car can lug around a higher percentage of payload (persons, cargo) rather than carrying around more car structure and batteries. &lt;br /&gt;
&lt;br /&gt;
For other purposes, biofuel pellets are desirable for heating fuel (after energy efficiency and solar thermal is maxed out) - such as by an aquaponic greenhouse with a black tubing heat exchanger.&lt;br /&gt;
&lt;br /&gt;
Biofuel pellets can be burned partly to release heat in winter - and if taken out of combustion after the volatile chemicals are burned off but before carbon burns to ash - then we have produced charcoal that can be used in a combustion engine. Thus, dual-fuel hydrogen/charcoal cars are in our view the transportation of the future. We are open to fuel cells entering the scene, and at $134/kW they are almost feasible.https://energy.gov/eere/fuelcells/fuel-cell-technologies-office-accomplishments-and-progress  They are too complex at this point for easy DIY production, so we may revisit this in 10 years if the technology becomes more accessible. Currently, fuel cells require exotic plastics and platinum, both of which are scarce resources. We are aiming for a sub $10k car which can be made with a standard internal combustion engine (ICE) running on hydrogen. Did you know that the first internal combustion automobile in the world ran on hydrogen in 1808? https://en.wikipedia.org/wiki/Fran%C3%A7ois_Isaac_de_Rivaz  Furthermore, ICEs are about 20% efficient - ICEs running on hydrogen are about 40% efficient. For comparison,  fuel cell vehicles are 50% efficient.http://environment.yale.edu/gillingham/hydrogenICE.pdf  Given that the efficiency gain of 25% of fuel cells over hydrogen ICEs comes at a 10x larger cost today, the case for pursuing hydrogen ICEs is much higher than the case for fuel cells. much cheaper H2ICE are seen by many experts as the means to provide a transition between emitting and non emitting transport and stationary system. https://pureenergycentre.com/hydrogen-engine/ &lt;br /&gt;
&lt;br /&gt;
Fig. The possible cost of a fuel cell car today for a 200kW sedan is $26k - and an overall minimum of about $75k. The open source hydrogen microcar is aimed at an under $10k cost and more than 100 mpg using widely available technology. (comparison of components and price, using ref 3 above)&lt;br /&gt;
&lt;br /&gt;
The answer already under our nose that is perhaps the most optimistic case for the energy revolution is solar power - at 0.015 cent per kilowatt-hour - demonstrated in 2016 by the Seed Eco-Home. http://opensourceecology.org/wiki/Hydrogen_Production  This is 4x cheaper than gas turbine electric generation  https://qz.com/135032/fuelcell-energy-fuel-cell-profit/  , and it allows for an equivalent 80 cent per gallon electricity cost for producing hydrogen.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
==The Power Cube==&lt;br /&gt;
&lt;br /&gt;
Our current Power Cube is a universal power unit that can power any of the large GVCS  machines, from cars to lathes to the brick press. The Power Cube is gasoline powered and has a 16 hp engine. We already ran this on charcoal gas - and as such - the same power cube can readily be used in dual-fuel operation - gasoline on the one hand, and charcoal on the other. Once we add the gas production infrastructure - the power cube can run on the hydrogen and biogas production from the House.  Because the pelletizer is part of the GVCS - we can make charcoal pellets from biomass pellets as a byproduct of space heating.  The concept of pellets is important - in that pellets are a flowable fuel. Meaning - that just like gasoline or tradition fuels - it can be stored in a tank and delivered as fuel as if it were a liquid - by using a small auger. This makes pellets a convenient fuel source, which unlike wood - can be used automatically in small machines.&lt;br /&gt;
&lt;br /&gt;
Moreover, the Power Cube can be run on solar energy, allowing for autonomous tractors and solar cars to enter. Solar power cubes are a good idea for shop power - where PV on the workshop roof feeds electric power cubes for hydraulic shop power. Power cubes can also be made very small - on the 1 kilowatt scale. They can also be stacked readily for higher power, so if we want a 160 hp bulldozer, we can do that based on our existing Power Cube.&lt;br /&gt;
&lt;br /&gt;
The Power Cube involves developing open source engines so that they enter the realm of lifetime design public technology. A universal version of an open source engine means that such an engine could be maintained and produced in a distributed fashion, bringing it closer to appropriate technology with a lifecycle that includes more reusability of parts.&lt;br /&gt;
&lt;br /&gt;
Fig. The Power cube and its different fuel sources - from gasoline, to charcoal, to compressed biogas, hydrogen, and electric.&lt;br /&gt;
&lt;br /&gt;
The large torque of hydraulics makes them very flexible for driving a wide range of machines. A small power cube, such as a 300W version running on a single solar panel, can be used to drive a 2000 lb MicroTrac as a practical, autonomous tractor.  The idea is that the machine would move very slowly - all day - on solar power. This is afforded by that fact that hydraulics have high torque at any speed - making this a perfect application of solar energy to autonomous, robotic tractor drive via a small microcontroller such as a $10 Pi Zero with Wireless.https://www.adafruit.com/product/3400   Thus, we can pull chicken tractors or pig tractors with a solar robotic tractor for a diversified agriculture operation.&lt;br /&gt;
&lt;br /&gt;
Fig. Infographic. Mega power cubes for 160 hp for a bulldozer, and a micro power cube for a solar grinder/pelletizer or chicken tractor.&lt;br /&gt;
&lt;br /&gt;
Autonomous animal tractors are another possible application of Power Cubes…&lt;br /&gt;
&lt;br /&gt;
Fig. The economic breakdown of an autonomous chicken tractor. PV panel + micro power cube at $500, plus the tracked drive for another $500 with open source hydraulic motors. The hydraulic motors (SME) are produced on the open source lathe (SME).&lt;br /&gt;
&lt;br /&gt;
==The Gasifier ==&lt;br /&gt;
&lt;br /&gt;
The OSE  gasifier is a device that converts charcoal into gas for fueling engines. Note that this gasifier uses charcoal that is produced as a byproduct of space heating. The gasifier is a metal container filled with charcoal, which upon being lit via in a small burn zone with an air inlet - burns and produces gas. This gas can be used as fuel in a regular internal combustion engine. The power of this lies in that with minimal modifications, a standard engine can be fueled by charcoal - which is derived from wood or other biomass.  This means that wherever plants grow - they provide a distributed and practical fuel source byond oil wars. https://www.cnn.com/2013/03/19/opinion/iraq-war-oil-juhasz/index.html  To produce charcoal, biomass is first pelletized. Burning pellets for space heat - and removing them from the burn before they turn to ash - produces charcoal pellets.&lt;br /&gt;
&lt;br /&gt;
Fig. Infographic. Space heating produces charcoal in the OSE ecosystem.  The Gasifier vaporizes charcoal, which is then burned in a standard engine. This process can be used to fuel cars - no engine modification required.&lt;br /&gt;
&lt;br /&gt;
The first reaction may be that if we turned plants into vehicle fuel - then we would destroy all of nature. That is not true, because there is plenty of biomass reserve that can be used to fuel the entire American car fleet, which uses about 60% http://needtoknow.nas.edu/energy/energy-use/transportation/  of all the energy in the transportation sector. Did you know that the largest single crop in the United States is lawn? There are 40 million acres of turf grass. http://scienceline.org/2011/07/lawns-vs-crops-in-the-continental-u-s/  What if we turned lawns into fuel crop, while increasing esthetics and reducing herbicides? Yields of grass are 4 dry tons per acre https://en.wikipedia.org/wiki/Biomass  - and if charcoal is produced at 25% efficiency - that is one ton of charcoal per acre - or 40 million tons of charcoal can be harvested from lawns alone, with no effect on food production, while increasing the ecological diversity of lawns. The average american uses 500 gallons per year of fuel.  https://www.treehugger.com/culture/pop-quiz-how-much-more-gas-do-americans-use.html  Lawns could thus provide ¼ of the entire car fleet fuel in the USA! (Charcoal is ¾ the energy content of gasoline by weight. At about 3 kg/gallon - 500 gallons is 1500 kg- about 1.5 metric tons - so 33M people could be supplied by fuel from lawns. If 95% of households have cars - https://photos.state.gov/libraries/cambodia/30486/Publications/everyone_in_america_own_a_car.pdf - and household is 2.6 - there are about 120M drivers in the USA. Thus  - ¼ of US drivers can be fueled by lawns.) This is at the crappy USA 23 miles per gallon - so increasing fuel efficiency to 100 mpg https://www.motherearthnews.com/green-transportation/green-vehicles/build-your-own-car-zm0z13amzmar with super-efficient micro-cars could mean that the entire US car fleet is supplied by fuel from grass. Efficiency and ecology - as opposed to battery technology with questionable environmental side effects and its centralization based on scarce resources - make the OSE platform converge on biomass and hydrogen as the fuels of choice. The OSE platform reserves the role of batteries only as a small part of vehicular power, not the backbone of the auto industry. &lt;br /&gt;
&lt;br /&gt;
The biomass route needs no technical invention to realize - today - and is also a carbon-neutral route. From the OSE perspective - hydrogen is clean (it produces water as the byproduct) but not better on ecological grounds (it does not contribute to biological ecology) - but it is much better on efficiency grounds.&lt;br /&gt;
&lt;br /&gt;
When discussing biofuels, it is important to point to the food-fuel-fiber integrated agroecology route as the preferred OSE route to agriculture. As opposed to genetic engineering to produce super-crops, the OSE platform favors ecological integration over genetic manipulation - so that we avoid creating super-problems at the same time. The ecological route means that we learn more about dealing with integrated ecosystems, not trying point solutions (genetic engineering) as a cure. When dealing with powerful technologies like genetic engineering, we must pay attention to unintended consequences. The current economic paradigm of profit maximization is not compatible with care in the use of genetic engineering. We favor increasing productivity by stacking yields of multiple crops that work harmoniously in a polyculture setting - with tree crops as a significant component. For us, the breakthrough work of Badgersett Research Farm is seminal in providing this leadership. They are developing perennial crops (hazelnuts and chestnuts) that could serve as a viable replacement for soybeans and corn. (ref).  Hazelnuts and chestnuts provide the same nutrition as their annual counterparts - but are perennial - and therefore do not contribute to the average 4 ton per acre annual soil erosion in the United States. (ref). Let me repeat that - the avarage topsoil loss in the United States - per acre - is 4 tons. What that means is that agricultural soils today are so depleted that they could not grow crops if it were not for the heavy inputs of fertilizers. The biological activity of commercial farmland is severely depleted (ref), not sustaining the soil food web of microbes that bring fertility back to the soil. (ref). Our proposition for perennial polyculture - is not new (ref on seminal works, Tree Crops, Regrarians, etc) - and it can produce food, fuel, and other materials.&lt;br /&gt;
&lt;br /&gt;
To improve the world, all you need to do is plant trees. Desertification still claims an additional ______________ square miles every year, and it would be good to reverse that.&lt;br /&gt;
&lt;br /&gt;
It takes less than 60x the land area to produce solar hydrogen compared to the land area required to grow biofuel crops.  Between biofuel (easy) and hydrogen (hard), humanity’s fuel needs can be met. Let’s look at numbers: we already said 300 gallons of fuel equivalent per acre (enough to fuel one car for a year at a fuel economy of 40 MPG https://www.google.com/search?q=average+miles+per+year+usa&amp;amp;oq=average+miles+per+year+usa&amp;amp;aqs=chrome..69i57j0l2.7415j0j7&amp;amp;client=ubuntu&amp;amp;sourceid=chrome&amp;amp;ie=UTF-8 ) fuel consumption -  roughly one gallon per day. If we apply this to hydrogen - 50kWhr of electricity is required to produce 1 kg of hydrogen, roughly one gallon gas equivalent. This can be obtained from a 9 kW PV array - running 6 hours per day - 54kWhr. The space required for a 9 kW array is 60 square meters if the panels are 15% efficient. An acre is 4000 square meters - so producing solar hydrogen requires 66 times less land area than growing the equivalent grass. Our materials cost for 9 kW of solar panels is under $9k. So one can obtain 20 years of hydrogen fuel for a PV investement cost of $17k.&lt;br /&gt;
&lt;br /&gt;
Fig. Home hydrogen production. The OSE open source goal is $9k for PV panels, $2k for storage, $2k for pump, $2k for plumbing, and $2k for the electrolyzer. That is $17k for a lifetime supply of hydrogen. Compare to gasoline - $1250/year on average. Payback time for  home fuel station is 14 years in the USA and 7 years in Europe. We intend to make hydrogen production a standard feature of the Seed Eco-Home.&lt;br /&gt;
&lt;br /&gt;
Add a paragraph about renewable energy plantations - perennial polycultures for fuel, food, fiber. &lt;br /&gt;
&lt;br /&gt;
Fig. Basic economic model for renewable energy plantations involves $x/acre in coppiced fuel, $1000/acre in nuts, and $2k/acre in sustainable chickens that fertilize the crop via autonomous chicken tractors.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
==Heat Exchanger==&lt;br /&gt;
&lt;br /&gt;
The heat exchanger is a device that takes heat from one medium and puts it into another. For example, in the Seed Eco-Home - we have a hydronic stove with heat exchanger which is used to heat water for heating the house.&lt;br /&gt;
&lt;br /&gt;
Fig. Hydronic stove with heat exchanger. A heat exchanger heats water, and if that water is boiled, it can be used to run a steam engine or turbine. Small steam engines have been used for shop power 100 years ago, and they can be used even more effectively today. You can get a working kit for $275 on Ebay.&lt;br /&gt;
&lt;br /&gt;
Simpler examples of the heat exchanger are the Hillbilly Heater. This device traps solar heat and puts it into water circulating through the black tubing. This energy is released through another coil in the aquaponic ponds, for example. A closed heat exchanger means that the water in the black tubing does not mix with the pond water. Or, this heat exchanger could be an open heat exchanger, where the water is heated and then used as hot water in a shower - so that a steady supply of new water is fed through the exchanger instead of just circulating - as in the pond heating case.&lt;br /&gt;
&lt;br /&gt;
Fig. The hillbilly heater can be used to heat ponds or to provide hot water for the house.&lt;br /&gt;
&lt;br /&gt;
==Modern Steam Engine==&lt;br /&gt;
&lt;br /&gt;
The modern steam engine is an engine that produces power from steam. The industrial economy was created by steam power. And steam turbines are the main way that power is generated today. &lt;br /&gt;
&lt;br /&gt;
A modern steam engine is a small engine that makes sense to build wherever space heating is involved. For example, a centrally heated building could be generating power at the same time as its being heated - if a heat engine with a generator is added to the system. Thus, we are piggy-backing on an existing power source, while using all the waste heat.&lt;br /&gt;
&lt;br /&gt;
Under 500 hp - or in any small scale installation - it is more effective to have a steam engine as the engine of choice. Above 500hp, it is more effective to use a steam turbine. Large power plant steam turbines reach 50% efficiency. https://en.wikipedia.org/wiki/Steam_turbine#Practical_turbine_efficiency &lt;br /&gt;
&lt;br /&gt;
A flame-fired or solar-powered heat exchanger can produce steam - for electricity generation. This makes sense for combined-heat-and-power systems. Most of today’s electricity is produced by water that is boiled in power plants to provide electricity via steam turbines. (ref) This can be done effectively on a scale of 500 or more horsepower - which is village scale, not home scale. For the smaller scale, a small steam engine can be used. For this reason, we have incorporated a modern steam engine into the GVCS - as a machine for producing electricity on top of a heat source. This could be done in our hydronic stove - where the water goes from the steam engine and then to house heating after some power has been extracted for electricity. It makes sense to convert the heat into high grade electricity - when the steam engine is connected to a generator.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
Did you know that the modern steam engine - a specific advanced version -  is more efficient than the internal combustion engine? The Cyclone engine is a high tech, high temperature steam engine made of stainless steel and exotic materials - with thermal efficiency over 30%. http://cyclonepower.com/ &lt;br /&gt;
&lt;br /&gt;
There is another steam engine that received a lot of attention on the internet but appears not to work well - the Green Steam Engine. We do not endorse the engine, as suggested by Tom Kimmel of Kimmel Steam Power  http://kimmelsteam.com/green-robertengine.html  - and you can read more in an old blog post. (http://opensourceecology.org/steam-meet-report/ . I have since contacted Mr. Greene for data on Feb 1, 2018, but I have not been presented with any data.)&lt;br /&gt;
&lt;br /&gt;
All together, the modern steam engine is valuable for household power, if the Power Cube is used for mobile power. Would would be the cost of a steam engine add-on to a household infrastructure? Small models of ¼ hp are available for under $300 in parts, (http://ebay.to/2EwmHWt ) and these are scalable readily to larger sizes. The current seed eco-home stove has sufficient power to run this engine, so only an additional pump would be required to feed water to this system.&lt;br /&gt;
&lt;br /&gt;
Integration of such a system would work well if pelletized biomass were used as fuel - and subsequently - charcoal would be produced for use in cars as a byproduct of household power generation. An interesting milestone would be an automated biomass energy system from an autonomous tractor-pelletizer - up to the production of charcoal as car fuel using gasifiers - all from one’s former lawn converted to bioenergy crop.  In such case, nickel iron batteries may be desirable in so far as excess energy storage from daytime solar power.&lt;br /&gt;
&lt;br /&gt;
Fig. The energy product ecology of the Seed Eco-Home includes solar hydrogen, biogas for cooking, and production of car fuel from the lawn.&lt;br /&gt;
&lt;br /&gt;
==Solar Concentrator==&lt;br /&gt;
&lt;br /&gt;
The modern steam engine equation becomes much more exciting when solar concentration is used. Using 30% efficient, modern steam engines, proven linear solar concentrators, and a night-time storage system based on large, insulated propane tanks with hot water - it is possible to produce an off-grid energy system with $100/kWhr energy storage costs - 4x cheaper than lithium ion batteries. https://en.wikipedia.org/wiki/Lithium-ion_battery  A breakthrough company - Terrajoule - has already demonstrated this. Then the question becomes - if this has already been shown in the first prototype of Terrajoule, why isn’t everyone doing this when the technology is all proven? One cannot beat the simplicity of water and solar heat as the ultimate storage medium. &lt;br /&gt;
&lt;br /&gt;
What can water really do? When water is heated but not allowed to expand, it turns to what is known as saturated water. A saturated liquid is a liquid whose temperature and pressure are such that any decrease in pressure without change in temperature causes it to boil. In other words, if a tank was not holding the water at pressure - that water would turn into steam.&lt;br /&gt;
&lt;br /&gt;
Just how much energy can that water store at a medium pressure? A lot. Looking at the total heat content of water that would otherwise turn to steam, but is held under pressure at 18 atmospheres (250 PSI) in a tank instead http://opensourceecology.org/wiki/Saturated_Water  - we see that each kilogram of such saturated water holds about ¼ kWhr of energy. That means that a 10,000 gallon propane tank can store about 4MWhr of energy! We can extract that energy with a modern steam engine, where steam engines from the 1950s got to about 30% efficiency. https://en.wikipedia.org/wiki/Uniflow_steam_engine   After all the losses, we we would have 300kWhrs of electricity when the modern steam engine runs a generator.&lt;br /&gt;
&lt;br /&gt;
We can scale that down to a residential system - just a 1000 gallon propane tank - and 30kWhrs of electricity produced.&lt;br /&gt;
&lt;br /&gt;
Fig. Cost and energy of a home-scale solar energy storage system using water and modern steam power. From energy content of 400kWhrs to 30kW hours of electricity is quite doable using proven technologies, at ¼ the cost of battery storage.&lt;br /&gt;
&lt;br /&gt;
==Nickel Iron Battery==&lt;br /&gt;
&lt;br /&gt;
Nickel-Iron Batteries are long-life batteries that have a track record of lasting 50 or more years. Unlike other batteries, these can be discharged fully without decreasing their lifetime. These are chosen for the Global Village Construction Set specifically for their long life - and becuase nickel and iron are not scarce resources. While heavier and 2x more expensive than lithium ion batteries, (Read an intereresting pro-con discussion - http://opensourceecology.org/wiki/Nickel_Iron_vs_Lithium_Ion_Battery_from_Tesla_Motors ) they make up by their long lifetime, and lend themselves to decentralized production. New developments are in progress, ( https://news.stanford.edu/news/2012/june/ultrafast-edison-battery-062612.html )  though OSE does not rely on new developments for feasibility given that OSE internalizes social and environmental aspects for true cost accounting. The cost is currently high because production volume is low - only 2 US manufacturers. Based on a nickel price of $6/lb and iron at 25 cents/lb, and a weight of 100 lb for 1kWhr - and a 20% content of nickel in nickel iron batteries https://www.solarpaneltalk.com/forum/off-grid-solar/batteries-energy-storage/ni/7052-how-much-nickel-is-really-in-a-ni ckel-iron-ni-fe-battery - the base materials cost of materials in Nickel Iron batteries appears to be $150/kWhr. That is similar to lead acid batteries and ½ of lithium ion costs - but if the lifetime of these batteries is really 50 years, then they are 5-10x cheaper than other batteries based on lifetime.&lt;br /&gt;
&lt;br /&gt;
According to recent research: https://link.springer.com/content/pdf/10.1007/s10800-015-0911-3.pdf &lt;br /&gt;
&lt;br /&gt;
There are many reasons favouring the use of NiFe cells as cost-effective solutions to store grid-scale amounts of energy, such as low cost of raw materials, environmental friendliness, electrical abuse tolerance, long life (in the order of thousands cycles of charge and discharge) and compatibility with photovoltaics (PVs). Due to the nature of the heavy metals involved in its construction this technology is suitable for stationary low gravimetric energy applications (30–50 Wh kg-1 ). As a consequence, there are good reasons to foresee a large scale utilization of this technology. Due to their outstanding safety properties (zero flammability, fail safe, no over/ under charge), low cost and long lifetime, we anticipate that they will receive widespread public acceptance for customer-connected energy storage.&lt;br /&gt;
&lt;br /&gt;
It is our hope that the nickel iron battery would be only a small fraction of electrical power storage needs in the future - such as replacing 5-year lifetime starter batteries in vehicles. For night time electricity, it would be useful for warmer regions to use solar concentrator saturated water storage - as one possibility - or solar hydrogen as another.&lt;br /&gt;
&lt;br /&gt;
In colder areas, biomass is typically available as an abundant energy crop - where PV may not be adequate if there are weeks without sun. The exact mix of solar concentrator electric, PV, wind, charcoal, biomass, biogas, and hydrogen is to be determined at Factor e Farm as we measure the value of all these systems side by side. The main requirement for OSE is true service to humanity, environmental regeneration, and freedom from resource conflicts.&lt;br /&gt;
&lt;br /&gt;
==50 kW Wind Turbine==&lt;br /&gt;
&lt;br /&gt;
A wind turbine converts a renewable form of energy - wind - into electricity. It provides a good backup to PV electricity, as wind typically blows when the sun is not out.&lt;br /&gt;
&lt;br /&gt;
We propose a vertical axis wind turbine for the initial OSE version based on integration with hydraulics and the Universal Rotor.  A simple system can consist of a pole mounted 40 hp hydraulic motor ($400), serving as a pump - which transfers fluid power to an on-the-ground hydraulic motor ($300) + 24 kW generator ($1000). The power generator related costs are ~ $2000 here, and the rest is the tower and structure. With $6k spent on the materials for this wind turbine, this would be $250/installed kW in materials costs - with installation being 15% on top of this http://www.esru.strath.ac.uk/EandE/Web_sites/14-15/XL_Monopiles/cost.html  - a very attractive package in a sweet spot of cost for readily-available components. This is compared to $1590/kW standard costs of large scale wind installations. https://www.awea.org/falling-wind-energy-costs &lt;br /&gt;
&lt;br /&gt;
The OSE design features a generator that is mounted on the ground, with only the hydraulic motor on top of the tower. This facilitates maintenance considerably. The savings is due in part to the great simplification of the nacelle - in the OSE case, the vertical axis design doesn’t have a yaw mechanism - it’s just a hydraulic motor that accepts wind from any direction. These turbines are not as efficient in terms of wind capture as they are lower to the ground - but the low capital + maintenance costs make up for the lower efficiency. Because they can be packed more tightly in the same area, however - VAWT wind farms can actually produce 10x the energy of a propeller-type wind farm. https://en.wikipedia.org/wiki/Vertical_axis_wind_turbine#Advantages  They also self-regulate their speed, so they do not need a braking meachanism for overwind conditions.&lt;br /&gt;
&lt;br /&gt;
Fig. OSE VAWT concept. Simplification of design include ground-mounted generator, yawless rotor, screw pile foundation https://en.wikipedia.org/wiki/Screw_piles#Modern_Use_and_Benefits  , and braking via the hydraulic motor as the overspeed protection. The wind turbine module is designed for 24 kW, and it includes the Electric Motor/generator, Universal Rotor, Hydraulic Motor, Power Cube, and Universal Power Supply for managing power.&lt;br /&gt;
&lt;br /&gt;
8. Universal Power Supply&lt;br /&gt;
The Universal Power Supply (UPS) is the last of the energy machines. It is a universal device for powering large electronic machines - induction furnaces, welders, plasma cutters, laser cutters - and for controlling power delivery and transmission to homes or electric cars. It is also used for charging. The UPS has feedback such that it would know when batteries are full, or for optimizing the power transfer into a load of metal that is melted with the induction furnace. &lt;br /&gt;
&lt;br /&gt;
The Universal Power Supply in general  converts AC and DC into voltages and currents of any amplitude and frequency. The UPS is scalable from a few watts to 20kW based on the same design of modules.  The Universal Power Supply can also be used to condition power from the wind turbine or PV system and pump it into the grid. It can also be used as an inverter to convert DC to AC, or it can be used to control the speed of an electric car. It can also be used to step power up to high voltage for power transmission over longer distances, such as up to the 69,000 volts for rural power lines. &lt;br /&gt;
&lt;br /&gt;
As with the mechanical machines, the Universal Power Supply is based on modular design, such that we can arrive at a Construction Set. Just like power units, wheels, shafts, hydraulic motors, control valves, and frames can create any mechanical industrial machine, so can a small number of modules provide just about any electrical power function in the Universal Power Supply. These modules are mainly: a microcontroller, a current measurement device, a transistor, wires, laminated cores, ferrite beads,  diodes, optocouplers, resistors, capacitors, and inductors - plus a few mechanical components such as plugs, cases, cooling systems. With advanced transistors that now cost $1 per kW of power handling, large power electronic devices can be built on the cheap if open source knowhow is available.&lt;br /&gt;
&lt;br /&gt;
Wires and metal cores themselves produce a wide range of devices: inductors, transformers, relays, solenoids, switches for large currents, electric motors, spark generators, electromagnets, and other devices. &lt;br /&gt;
&lt;br /&gt;
Lasers, charge controllers, inverters, welders, induction furnaces, plasma cutters, oxyhydrogen generator power supply, and motor controllers are all functions that can be generated with the Universal Power Supply. These are all based upon currents and voltages at different frequencies and amplitudes that perform radically different functions. This has to do with the nature of electricity - jus like a few atom types (100 or so) make up millions of different substances that are all around us - so can electricity be manipulated to perform a wide array of functions. Any of the above devices consist of a microcontroller and a power transistor - along with some resistors, capacitors, and inductors. The microcontroller could be an Ardduino or a Rasperry Pi - which now cost as little as $5 for these small computers running with a 700MHz cpu. This CPU - via software - can produce a voltage of any amplitude and frequency using transistors. In other words - a ‘brain’ - the CPU - can massage electrons so they maifest at any voltage or frequency - by using transistors - or devices where a small signal from a CPU controls a large voltage. Essentially - a transistor is a switch - which is activated by a small signal.&lt;br /&gt;
&lt;br /&gt;
For example - taking DC voltage - one can make it pulsed and appear as an oscillating sine wave. This is an inverter for household power - which can for example take electricity from PV cells and convert that into household current. Or - this same inverter can be pulsed much faster to create a 30kHz voltage used in an induction furnace. And regulation can happen - such as an induction furnace delivering power most effectively to the molten charge - when the same microcontroller can measure the voltage, and change the frequency of the applied voltage to pump power more effectively into the melt. &lt;br /&gt;
&lt;br /&gt;
This is all possible because superfast microcontrollers, and high power handling transistors - can all be purchased now for a few dollars.&lt;br /&gt;
&lt;br /&gt;
Energy Summary&lt;br /&gt;
&lt;br /&gt;
Combining biomass, charcoal, biogas, wind power, the solar concentrator,  steam electricity, hydrogen, PV - and the electronic controls of the Universal Power Supply -  makes for a resilient power infrastructure without necessitating resource conflicts.&lt;br /&gt;
&lt;br /&gt;
=Open Source Microfactory=&lt;br /&gt;
&lt;br /&gt;
The Open Source Microfactory (OSM) is the crown jewel of the Global Village Construction. It is the part that allows for GVCS self-replication - in that the Open Source Microfactory allows for the production of all the  GVCS tools - including the Microfactory itself..&lt;br /&gt;
&lt;br /&gt;
The Open Source Microfactory is broken into 2 main parts: precision CNC tools, and metal production tools. The CNC tools - which stands for Computer Numerical Control - are automated machines that can be programmed to build things - from small parts, to engines, and everything in between. The metal production tools allow for the production of virgin steels from scrap. The steel that can be produced with the GVCS metal tools thus allows for the creation of advanced civilization - wherever there is access to scrap steel. Scrap steel is abundant, and so it iron ore from which steel is made. Iron is the 4th most abundant element in the earth’s crust - after oxygen, silicon, and aluminum. https://en.wikipedia.org/wiki/Abundance_of_elements_in_Earth%27s_crust &lt;br /&gt;
&lt;br /&gt;
What if there is no scrap steel available? We can go to aluminum - which is even more abundant in terms of the crust’s composition. Aluminum is found in common clay. Clay is aluminosilicate, from which aluminum can be extracted. Because Aluminum is so abundant - the GVCS goes so far as the extraction of aluminum from clay. This is intended to break through any notions of scarcity in today’s civilization.  Clay is abundant, and it’s an essential part of the GVCS: compressed earth blocks, soil for growing food, clay for 3D printed pots and cookware - in addition to the production of aluminum metal.  &lt;br /&gt;
&lt;br /&gt;
Fortunately - silicon is even more abundant. We get solar cells for producing electricity from silicon - a core technology for the GVCS such as in the Seed Eco-Home. In less than the time it takes to read this paragraph, the sun will have provided as much energy to Earth as used by all of human civilisation in one day. Thus silicon solar cells are important. And silicon is used to make semiconductors - so silicon creates the computer age.&lt;br /&gt;
&lt;br /&gt;
With the Open Source Microfactory - we thus aim to show that literally, modern civilization may be created -  from dirt and twigs. This can happen on any parcel of land - as solar cells can easily produce about 500kW of energy - from an acre. So a facility such as the OSE headquarters can produce all the technology required to produce an advanced civilization. For example, 500kW of solar energy - or 3MWhrs per 6 hours of daylight - can produce 200 kg of aluminum per day. Aluminum requires 15 kWhr per kilogram to smelt. (http://wordpress.mrreid.org/2011/07/15/electricity-consumption-in-the-production-of-aluminium/ . This one says ,05 GJ/kg - http://wordpress.mrreid.org/2011/07/15/electricity-consumption-in-the-production-of-aluminium/ )Aluminum is energy intensive - but its production may one day be improved for more environmentally-sound production - as can any other process by internalizing environmental costs.  https://www.sciencedirect.com/science/article/pii/S0360544207001065#! &lt;br /&gt;
&lt;br /&gt;
This shows how energy intensive aluminum production is - but its 3x better weight to strength ratio compared to steel makes it a desirable product. With the proposes 200kW solar microfactory - we can produce 80 kg of aluminum per day. That’s not a lot - but acceptable as a proof of concept for an appliance-size machine.&lt;br /&gt;
&lt;br /&gt;
Aluminium is the most abundant metallic element in the Earth’s crust (about 8%) and the&lt;br /&gt;
second most widely used metal next to steel. The aluminum production process involves taking ordinary clays such as abundant kaolin clay - and leaching out alumina with hydrochloric acid to produce Al203, which is subsequently turned to Aluminum via electrolysis at a cost of 15 kWhr per kg of aluminum produced. For reference in terms of energy requirements - this is like converting one gallon of gasoline to one kg of aluminum. That’s a lot of energy. But the main point here is that this can be done anywhere where there is soil - clay for making aluminum is an abundant feedstock.&lt;br /&gt;
&lt;br /&gt;
If we talk about the carbon dioxide emissions - whether from aluminum or steel production - the way we propose to make it sustainable is to make the CO2 recyclable. If the carbon involved in the reactions for producing metals - or for that matter any other product - comes from charcoal derived from biomass - then the industrial process is regenerative as the plants that were used to produce the charcoal took the carbon out of the atmosphere in the first place. Thus, a sustainable industry is possible  when civilization evolves to using charcoal  instead of fossil fuels. &lt;br /&gt;
&lt;br /&gt;
However, it should be stated that CO2 in the long run may be more advantageous for ecology - even from fossil fuels - if that CO2 yields more plant growth. While many people see CO2 per say as a global warming problem - it is also possible that the CO2 will make the earth more green. Nobody knows what will happen at this point - we can only speculate as to the long term effects of increasing CO2 in the atmosphere. &lt;br /&gt;
&lt;br /&gt;
The open source microfactory is intended to produce an entire technosphere from local resources, pushing the limits of what can be done:&lt;br /&gt;
&lt;br /&gt;
Fig. Open Source Microfactory cyclic material flows can be based on local resources. Metals, bioplastics, ceramics, PV cells, concrete, carbon, hydrogen, glass, rubber, fuels, food, construction materials, and many other chemicals can be produced from local abundance.&lt;br /&gt;
&lt;br /&gt;
If it is indeed that PV cells can be made from local sand, and aluminum from clay - and everything else as noted - then we have truly stepped into a world of post-scarcity. At the point where material production is guaranteed, it may be possible for people to evolve full time - without being held back by mere survival. That is the essence of society that OSE intends to create - one in which material needs are not in the way of human evolution.&lt;br /&gt;
&lt;br /&gt;
For any other processes of industry - the Open Source Microfactory can provide. If you can make buildings, glass, metal, and plastics + other materials - you can build anything. Advanced processes such as chemical plants or semiconductor fabs - are nothing but buildings, metal vessels, motors, vacuum pumps, and a few other basics - and from there spews out any product - in a nutshell. This does not even involve the nanotech of molecular manipulation - where it is deemed that in the future we will be able to synthesize substances by moving atoms directly - without regard for chemical reactivity as we know it today. Yet we do not invoke the Technological Singularity as a prerequisite for meeting all human needs.&lt;br /&gt;
&lt;br /&gt;
Let’s move to the specific tools in the Open Source Microfactory:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
And &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Fig. Tools of the Open Source Microfactory. They include everything needed to produce precision metal parts starting from scrap metals, glass, bioplastics, and even semiconductors for solar cells. &lt;br /&gt;
&lt;br /&gt;
==Universal Axis==&lt;br /&gt;
&lt;br /&gt;
Six of the Open Source Microfactory tools are based on the Universal Axis. The Universal Axis is a modular, and scalable CNC axis which can be used to create cartesian CNC machines. The core of the axis design is belt drive and linear motion rods where carriages are pulled on the rods. The system is scalable to any size and number of axes, including rotary axes. The system uses a combination of 3D printed parts, metal plates, and belt-driven shafts. Applications include 3D printers, CNC torch tables, heavy duty CNC machines, and many other production machines.&lt;br /&gt;
&lt;br /&gt;
We intend to use the 5/16”, 1”, and 2” versions for 3D printers, CNC torch tables, and heavy duty CNC machines - which are among the key machines that can be built with the system - though a variant of any size and shape can be designed.&lt;br /&gt;
&lt;br /&gt;
Fig. The universal axis comes in 5/16”, 1”, and 2” variations, and is based on belt drive, though a screw and nut system can also be used as a drive. Various tool heads can be attached. Non-contact tool heads are attached magnetically, such as the laser cutter and 3D printer. Rotary attachments can even be used for 3D scanning or indexing.&lt;br /&gt;
&lt;br /&gt;
For heavy duty applications, the plastic plates may be reinforced with steel plates - making a steel-plastic composite that has the required strength - while being easy to produce because the complex geometry is 3D printed. The metal plates themselves can be CNC cut using the CNC torch table. This allows for the lowest cost route - the 2” bushings capable of 8000 lb force on these axes currently cost only $9.41 at McMaster Carr.&lt;br /&gt;
&lt;br /&gt;
Fig. Metal-plastic Universal Axis System.&lt;br /&gt;
&lt;br /&gt;
The power of the universal axis lies in its flexibility. The same design of the drive system can be used to make an unlimited range of fabrication machines, putting the manufacturing process completely in the hands of anyone - without high barriers to entry. This is aimed at the Open Source Microfactory in every town, where our goal is to distribute at least 10,000 of these open source microfactories around the world, each generating at least $100,000 of net revenue per year. Once production returns to communities, we expect that taxes will go down as communities once again become responsible for their own prosperity.&lt;br /&gt;
&lt;br /&gt;
==The 3D Printer, Bioplastic Extruder, 3D Scanner==&lt;br /&gt;
&lt;br /&gt;
The 3D printer is a machine with diverse applications. Essentially, the technosphere is made from plastics, ceramics, and metals. 3D printers can print with all of these, and are as such ubiquitously applicable to manufacturing of all sorts. Currently, it is easy to print with all kind of plastic, including rubber for printing tires and polycarbonate for printing glazing. It is likewise easy to print ceramics - by printing clay and then baking it. Here we can produce ceramic cookware or clay parts such as insulators or building bricks. If the clay contains a large fraction of glass or metal - then upon kilning - 3D printed glass and metal objects can be printed as well. Metal printing can also happen via a MIG or TIG welder as the working toolhead - where large metal structures can be printed additively like this. If we go a step up to lasers - we can do selective laser sintering of any kind of powder - from plastic, to ceramic, to metal. Extremely strong, precise metal parts can be created this way - such that for example the rocket engine for Elon Musks’s SpaceX rockets has been 3D printed.&lt;br /&gt;
&lt;br /&gt;
Fig. Different applications of 3D printing: plastic, rubber, glass, metal, ceramic, and housing.&lt;br /&gt;
&lt;br /&gt;
Carbon fiber or metal fibers can also be embedded in plastic 3D prints to make the parts as strong as aluminum. 3D printing can also print ceramic molds which can then be used for casting directly into these molds - using either molten metal from an induction furnace or a MIG weld right into the metal form.&lt;br /&gt;
&lt;br /&gt;
Fig. Apparatus for automated metal casting using 3D printing of molds + induction heating of melt to fill the molds.&lt;br /&gt;
&lt;br /&gt;
Currently - open source printing includes  plastic + rubber 3D printing, welder 3D printing, clay printing for ceramics, clay-metal 3D printing for metals, selective laser sintering of plastics, and 3D priting of concrete or clay buildings. With a little bit of work,  the full printing with metal or glass using selective laser sintering can be developed by using off-the-shelf technologies. An 80W laser tube like in the Laser Cutter + shielding gas allows for selective laser sintering of off-shelf metal powders. http://opensourceecology.org/wiki/Metal_Selective_Layer_Sintering#Literature &lt;br /&gt;
&lt;br /&gt;
Fig. If metal powder is available (it is, such as iron at $1/lb) - then we can use a laser to fuse a powder bed to complex 3D objcts that cannot be produced in any other way.&lt;br /&gt;
&lt;br /&gt;
The world of 3D printing is in its infancy - and this is definitely worth refining to achieve full 3D printability in any material. Perfecting all of the above 3D printing can go far towards local production of just about anything.&lt;br /&gt;
&lt;br /&gt;
==Bioplastic Extruder==&lt;br /&gt;
&lt;br /&gt;
The Bioplastic Extruder is part of a system that enables the production of biodegradeable bioplastics from natural feedstocks such as cellulose or sugars. The system includes 3D printing filament production as well as direct extrusion of useful parts.  &lt;br /&gt;
&lt;br /&gt;
Four main aspects are involved in the Bioplastic Extruder System. First, a bioplastic reactor is used to make bioplastic from abundant biological feedstocks such as cellulose, sugar, or starch. Second - once the plastic is produced - or is available from the waste stream - it can be extruded with the Bioplastic Extruder to make 3D printing filament. Third, the 3D printing filament is then used directly in 3D printers to make useful objects. Fourth, other useful products can be made with the extruder: plastic lumber, which can be made from recycled plastic and sawdust. This could be a great way to recycle plastics into durable construction materials. Other useful profiles - such as tubing and glazing panels - can also be produced with the bioplastic extruder. Thus, the bioplastic extruder per se can be used for 2 main purposes: making 3D printing filament as an intermiediate feedstock for 3D printers - or extruding useful products directly.&lt;br /&gt;
&lt;br /&gt;
Fig. The bioplastic production system of the GVCS consists of bioplastic synthesis followed by extrusion to produce 3D printing filament, tubing, sheets, or plastic lumber. 3D printing filament can be used for 3D printing. Thermoplastic elastomers - or rubber - can also be printed.&lt;br /&gt;
&lt;br /&gt;
There are 3 types of bioplastics - those derived from: (1) petroleum and biodegradeable; (2) biomass and biodegradeable; and (3) biomass and non-biodegradeable. OSE is most interested in bio-based, biodegradeable bioplastics, as the feedstocks are most widely available and can be produced ecologically anywhere in the world. &lt;br /&gt;
&lt;br /&gt;
The OSE bioplastic system allows for local recycling such that the plastic never ends up in the landfill - but is either reused or recycled. By eliminating plastic waste and turning it into valuable products, wealth can be multiplied. Also, we can clean up the environment by reusing plastics - which can otherwise persist in the environment for 1000 years. Such recycling also reduces the need for petroleum - the typical feedstock of plastics.&lt;br /&gt;
&lt;br /&gt;
Bioplastics derived from biomass that are non-biodegradeable can be produced from petroleum substitutes. Petroleum can be replaced with charcoal. As such, any plastic typically derived from petroleum can also be produced from renewable, plant-derived charcoal. In the OSE system, plant matter is pelletized, then burned partially for space heating or process heat - with the byproduct being the important charcoal feedstock. If one is interested in replacing petroleum-derived chemicals - charcoal is first burned in a gasifier to produce CO and H2 - just as the gasifier fuels regular engines with CO and H2 - a combustible mixture. Instead of being burned in an engine as a renewable fuel, these molecules can combine under heat and pressure and an iron catalyst to produce long hydrocarbon chains and water. The long chains are alkanes - the typical long-chain molecules of -[CH2]- found in petroleum. This conversion process is known as Fischer-Tropsch synthesis, and is important from the abundance mindset - in that all products than now come from coal and petroleum can be made more ecologically - from plants. https://en.wikipedia.org/wiki/Fischer%E2%80%93Tropsch_process  &lt;br /&gt;
&lt;br /&gt;
Fig. The circular economy of OSE is based on wood - to make charcoal, paper, bioplastic, rubber, and fuel.&lt;br /&gt;
&lt;br /&gt;
Cellulose acetate is a bioplastic that is easily made from the most abundant organic polymer in the world - cellulose. It can be made readily from trees. Did you know that wood fibers can be converted to this bioplastic by reacting these fibers - with glacial acetic acid? The product is 3D&lt;br /&gt;
&lt;br /&gt;
printable.http://www.designforcraft.com/new-materials-for-3d-printing-cellulose-acetate/  You can make windows with it.http://nvlpubs.nist.gov/nistpubs/jres/19/jresv19n4p367_A1b.pdf  Instead of trees, one can use any source of cellulose - paper, cotton, straw, or other cellulose materials. &lt;br /&gt;
&lt;br /&gt;
Straw and wood are thus very important in the overall product ecology for making fuel pellets, insulation for the Seed Eco-Home (with borax), strawboard, charcoal, paper,  steel (charcoal with iron ore), and bioplastics.&lt;br /&gt;
&lt;br /&gt;
Polylactic Acid, or PLA, is the most popular bioplastic used in 3D printing. It can be derived from bacterial fermentation of sugar - and is thus an accessible technology within the GVCS.&lt;br /&gt;
&lt;br /&gt;
Polyhydroxyalkanoate (PHA) or polyhydroxybutyrate (PHB) bioplastic polyesters are considered the best candidates to replace the current petroleum-based plastics due to their durability in use and wide spectrum of properties. https://www.intechopen.com/books/biotechnology-of-biopolymers/conversion-of-biomass-into-bioplastics-and-their-potential-environmental-impacts  They are made by bacteria from sugar or starch at an efficiency of up to 80% of bacterial cell mass.https://www.intechopen.com/books/biotechnology-of-biopolymers/conversion-of-biomass-into-bioplastics-and-their-potential-environmental-impacts  Some PHAs are elastomers. Thus - it is realistic to include rubber production for tires - from sugar or starch - within the industrial ecology of the GVCS. Unlike latex resin from dandelion roots - which can be used to produce thermoset plastics - PHA rubber is thermoplastic, so it can be recycled easily. Both PHA rubber and dandelion root rubber can be grown anywhere - thus removing the strategic importance of tropical rubber tree plantations. It appears that PHA rubber is more viable from the decentralization perspective. Wood, broken with acid to simpler sugars - can also be used a feedstock for PHA - thus making PHA rubber production possible anywhere in the world. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4964529/   However, woody crop can compete with food crops - so we once again emphasize perennial polycultures as ways to produce food, fuel, and fiber. With perennials, it is also easier to use degraded lands, which can be regenerated back to fertility and health when annual crops are removed from the equation.&lt;br /&gt;
&lt;br /&gt;
In addition to sugar and cellulose, starch from common sources such as potatoes or corn can be polymerized readily in the kitchen. For example, mixing vinegar and glycerine with the starch makes a bioplastic.http://opensourceecology.org/wiki/Starch_Bioplastic   This is the easiest route  that can be used for 3D printing&lt;br /&gt;
&lt;br /&gt;
The bioplastic extruder has 2 main functions: one is to perform extrusions directly - or to produce intermediate 3D printer filament which is then used to 3D print final objects. For the latter, we are currently building upon two open source projects working on plastic extruders: the Lyman Filament Extruder,http://opensourceecology.org/wiki/Lyman_Filament_Extruder  and the Thunderhead Filament Extruder from Tech For Trade.http://opensourceecology.org/wiki/TechforTrade  These are simple versions of plastic extruders - which if scaled up and made more robust - can produce not only 3D printing filament, but larger extrusions.&lt;br /&gt;
&lt;br /&gt;
==3D Scanner==&lt;br /&gt;
&lt;br /&gt;
The 3D scanner allows for scanning of 3D objects to produce Computer Aided Design (CAD) models for reverse engineering. This is very useful - as we can take existing parts and digitize them for use as editable CAD models. A single camera can be used for photogrammetry, which is a computational technique for converting a set of pictures of an object taken from multiple angles into a 3D object.http://opensourceecology.org/wiki/Open_Source_Photogrammetry There is a number of open source programs that can do this. A 3D digital object can also be generated using multiple cameras, laser beams, or other light sources reflected from an object. As the simplest route, OSE  will build on existing work to develop the toolchain and procedure for photogrammetry - as that requires no hardware outside of a simple camera and a computer to process the images. If markers are used on objects, accurate CAD can be generated with proper dimensions. &lt;br /&gt;
&lt;br /&gt;
It gets more interesting: we can 3D scan internal features, too. This is known as industrial Computed Tomography (CAT) - essentially - a CAT scan for metal objects. By using an x-ray or gamma ray source - and then photographing an image - we can build a low-cost DIY CAT scanner.https://www.youtube.com/watch?time_continue=25&amp;amp;v=hF3V-GHiJ78  http://www.tricorderproject.org/blog/tag/openct/  Combined with an open source code base for image processing  from CERN, 3D industrial tomography scans can be obtained.https://home.cern/cern-people/updates/2016/09/new-open-source-medical-imaging-tools  &lt;br /&gt;
&lt;br /&gt;
==CNC Circuit Mill + Small Laser Cutter==&lt;br /&gt;
&lt;br /&gt;
We have already prototyped a circuit mill - the D3D CNC Circuit Mill.http://opensourceecology.org/wiki/D3D_CNC_Circuit_Mill  This shows a great example of the Unversal CNC axis modularity - where we have used the same motion system as in the 3D printer - but now strengthened the motion system by doubling the x axis to hold a small router. While the 3D printer is a non-contact manufacturing method - the circuit mill requires that the axes withstand contact forces of the milling operation. The strong, steel space frame of the D3D platform can handle these forces.&lt;br /&gt;
&lt;br /&gt;
Furthermore, other tool heads can be used on the Universal Axis. One useful example is a small 4W laser cutter, which cut up to ¼” plywood for prototyping purposes.&lt;br /&gt;
&lt;br /&gt;
Fig. The OSE CNC circuit mill and example circuits produced. The Router Tool Head is one of many tool heads that can be used on the Universal Axis system. A small laser is another, and can be retrofitted readily. The laser cutter toolhead allows for cutting cardboard for rapid prototyping. (4-picture - mill+product, laser+product)&lt;br /&gt;
&lt;br /&gt;
Prototyping with a laser cutter is important to the GVCS because the laser cutter can simulate the cutting that is typically done with a CNC torch table. Just like the CNC torch table typically cuts ½” thick flat parts out of sheet steel - the small laser cutter can cut parts out of paper stock. These parts can then be glued or fit together - just like the CNC-torch-cut metal parts are welded to make real-life 3D machines such as the CEB Press.&lt;br /&gt;
&lt;br /&gt;
Fig. Flat metal is used to generate 3D objects by welding. We thus use 2D cutting to create 3D objects.&lt;br /&gt;
&lt;br /&gt;
An open source project for a larger laser cutter - the 100W Lasersaur - is already well-developed. We can use this platform to build upon as well, to reduce cost from its current $7k to something more on the scale of $3k for a large format laser cutter. The Universal Axis could be applied here, such that only the laser system ($2000) remains as a significant cost - and the rest of the system is ($1000). This would be another great application of the Universal Axis to show its flexibility.&lt;br /&gt;
&lt;br /&gt;
Another useful example of a practical tool-head is a ceramic 3D printer head - which is an extruder for clay materials that can be fired to make functional ceramics. Examples of very useful ceramics are insulators and pottery - especially stovetop cookware made of flameware clay - which can replace commercial cookware and provide artistry in the open source Seed Eco-Home kitchen.&lt;br /&gt;
&lt;br /&gt;
Fig. The ceramic print head allows for the production of practical objects such as pots and pans for cooking, bringing artistry back into the kitchen.&lt;br /&gt;
&lt;br /&gt;
Collaborative Prototyping + Model Kits + Product Ideas + The Open Source Everything Store&lt;br /&gt;
&lt;br /&gt;
With access to the OSE Developer Kit - 3D printer, CNC Circuit Mill, and Laser Cutter - all as different tool heads on the same Universal Axis system - collaborators access a powerful capacity to prototype the larger machines of OSE. Using these tools, accurate scale models can be built. This can extend the collaboration capacity on OSE machine development significantly. There are 4 major ways that collaborative prototyping can be done using the 3-in-1 Universal Axis machine. &lt;br /&gt;
&lt;br /&gt;
First, there is collaboration is CAD verification. Computer Aided Design (CAD) is used in the OSE design process in order to save countless hours during the build. In a proper design process, it is easier to design in virtual CAD - and figure out how everything fits together - rather than going straight to a build and having to fit everything on the fly. The ability to model accurately in CAD is the power that allows OSE to do builds on the scale of a day - as opposed to weeks. However - this works only if the CAD is accurate, because if the CAD drafting is not accurate, it may be impossible to build a machine. CAD quality depends on the skill of the draftsperson. For this reason, it is important to verify the CAD as one of the steps that takes place prior to a build. If mistakes are not caught prior to the build, time and materials are wasted, people can get frustrated, and schedules are delayed.&lt;br /&gt;
&lt;br /&gt;
How do we guarantee that a machine can be built as drafted? With an accurate scale model. First, we must make sure that the CAD of individual parts is correct. This can be assured when accurate CAD files are available - whether the files are generated from measurements, provided by manufacturers, or 3D scanned with the open source 3D scanner. Second, we can verify the actual buildability. This can be done by laser cutting from paper the parts that would be CNC Cut from steel, and then 3D printing the components that we would otherwise get off-the-shelf. For the 3D printing - it is critical that we print every single part - up to bolts and nuts - so the entire assembly we can verify every single step of the build.&lt;br /&gt;
&lt;br /&gt;
This leads to the second use of collaborative prototyping - producing build instructional manuals and videos using the scale models. This allows contributors all over the world to produce meaningful content - without requiring that the contributors have access to a workshop. Since qulaity intstructionals production requires as much effort as the design work - this is another way to contribute to a large, parallel development effort.&lt;br /&gt;
&lt;br /&gt;
The third route to collaborative prototyping is the production of Model Kits for actual products. For example, the Seed Eco-Home lends itself very well for such modeling. Another company, Arckit (ref), is a good model for how we can design the model kit for the OSE’s collaboration with the Open Building Institute.&lt;br /&gt;
&lt;br /&gt;
Fig. Arckit is a great example for modeling. In the OBI case, the models correspond to real building panels and real build procedures. This makes the OBI Architecture Kit a tangible way for people to get involved in meaningful design of future house models.&lt;br /&gt;
&lt;br /&gt;
The OBI Architecture Kit lends itself well to 3D printing as well as laser cutting. 3D printed parts would snap together like Lego blocks.&lt;br /&gt;
&lt;br /&gt;
Another model kit that would be very useful to GVCS prototyping is the Machine Build Kit -  a kit for producing tractors, heavy equipment, and other automated machines. Combined with the OBI Arch Kit for buildings - this would produce the Civiliation Model Kit. The concept for the Machine Build Bit is a mixture of Lego Mindstorms, MakeBlock, Erector Set, Capsela, Box Beam Sourcebook, and Solar Micro Power Cube (all refs) - so that the system can run on solar power. The value proposition is that the kit would once again be based on real buildable parts - thus extending its use from childsplay to real design work.&lt;br /&gt;
&lt;br /&gt;
The OSE Developer Kit + Model Kits pave the way for the 4th route to collaborative prototyping - that of developing open source enterprise. These 2 kits are products in themselves - and can be used as the basis for collaborative business development of distributive enterprise (ref). The concept here revolves around reaching the $1T tipping point for the open source economy - the point at which mainstream adoption of open source economics is likely ($1T is calculated as the 10% tipping point at which viral adoption of open source economics can occur. This coincides with the next Enlightenment of humanity - see Tipping Point on the wiki - http://opensourceecology.org/wiki/The_Tipping_Point  ). This is as large as the combined revenue of Apple ($229B), Google ($79B), FB ($41B), Amazon ($178B), and Walmart ($486B) combined (Microsoft ($90B) - not includes so total is $1T.) - the latter being the single largest corporation in the world.&lt;br /&gt;
&lt;br /&gt;
OSE’s distributive enterprise approach to the tipping point is distributive. The core of OSE’s economic theory is that, by definition, a distributive enterprise serves its customers more effectively than any proprietary enterprise. Thus, a DE has a high likelihood of deposing the corporation http://opensourceecology.org/wiki/The_Corporation  as the dominant societal institution, replacing it with the next phase of the human economy - the open source economy. The transition is in our view likely - because the goal of a distributive enterprise is to produce free enterprise - defined as  distributing wealth most equitably. Current economic paradigms do not internalize distribution in their economic models. The next economy is achievable via full cost accounting and zero competitive waste, thereby achieving zero marginal cost (ref ZMCS). This proposition is simple to grasp, but most challenging to execute. We are not interested in DE as an ideology - but as a pragmatic proposition that simply meets needs more effectively - in an integrated sense -  than current models.&lt;br /&gt;
&lt;br /&gt;
The ask for distributive enterprise is to create the Open Source Everything Store - a networked and collaborative store based on Open Source Microfactories. That is - for people to collaborate on open source product development as a massive parallel effort. Decentralized, distributed, networked production is not a new idea - many people love and claim the idea as their own. To date no successful, economically-viable implementation exists, and certainly not open source. There were many attempts, from the FabLab, Local Motors, 1000 Garages, Ponoko - but none are both distributed and open source. The FabLab is a distributed microfactory concept, but none of its machines are currently open source. FabLabs are are externally funded, and none are used to run a successful business. Local Motors works on distributed production, but their designs and microfactory tools are not open source. 1000 Garages appears stalled. Ponoko and many operations like Ponoko are available. They are successful enterprises, but they do not use open source production tools or software. None of these projects provide open source enterprise information. Perhaps the best examples are 2: first, Lulzbot, which shares its machine designs and enterprise blueprints (blog post from 2014 visit, google Distributive Enterprise) - which makes it a fully open source hardware company - but it has a centralized business model. Second, there is the poster child RepRap project - which is the design/collaboration repository for open source 3D printers. RepRap is responsible for producing most of the consumer 3D printing industry’s companies - both open source and proprietary. (ref) However, RepRap in itself does not have a revenue model. Our own work is also based on the RepRap - it’s the basis that saved us hundreds of development hours - as we could simply build upon their designs. We do have a successfully-demonstrated revenue model of ongoing Extreme Manufacturing workshops.&lt;br /&gt;
&lt;br /&gt;
For The Open Source Everything Store (TOSES), any product developed must include open source blueprints, as well as open source enterprise documentation. Assets such as marketing materials, revenue models, business plans, projections, and entrepreneurship training - among others - must be included to facilitate startup by others. For successful startup - the enterprises themselves must be tested and proven. Thus, case studies of projections, actual revenue, and growth must be included. &lt;br /&gt;
&lt;br /&gt;
With as small an infrastructure as a Personal Microfactory with 3D printing, the CNC circuit mill, laser cutter, filament extruder, and off-shelf components - production of many valuable products can be distributed far and wide. Moreover, open design allows for extended product lifetime - as parts can be upgraded, modifications can be 3D printed, and breakages fixed with readily-accessible parts.  The success of TOSES  revolves around a massive parallel open source product development process - resulting in best-in-class products. These products are then produced by distributed players. Thus, a networked effort could reach substantial distributed production - and distributed sales volumes on the scale of Amazon. &lt;br /&gt;
&lt;br /&gt;
Our claim is that Distributive Enterprise has a good chance of succeeding because of its distributive nature. The cost structure of distributive development is efficient - as it relies on an open source process. We are assuming here that the zero marginal cost prediction - that everything trends to zero marginal cost - which is the competitive advantage of TOSES. However, zereo marginal cost is inherently impossible within the current system. The profit motive of the corporation prevents zero marginal cost, and leads to a permanent inefficiency in human economics. This can be resolved only by a transition away from the traditional corporate IPO form (ref). This is the reason why OSE proposes that a transition to the open source economy is inevitable. However, leading economic theorists such as George Gilder claim that human constructs are not inevitable - they have to be created. Thus, it remains up to human will to decide whether we would like to implement true-cost accounting to transition to the open source economy.&lt;br /&gt;
&lt;br /&gt;
The choice is up to us, and as such we are working on the DE model. Once open source product and enterprise blueprints are available - it means that everyone has access to them. This indicates that efficient production can be distributed into a networked form, which can gobble up Amazon and Walmart. Such a transition to the true-cost accounting economy is the promise of open source economics.&lt;br /&gt;
&lt;br /&gt;
In practice, this requires that open source microfactories, as well as open source materials production facilities - are distributed far and wide. These take abundant natural resources and convert them to a modern standard of living in a distributed way. People can produce with their personal microfactories. Using the 3D printer, circuit mill, laser cutter, and filament extruder - and off-shelf components - people can produce many household goods, electronic gadgets, toys, tools, kitchenware, small appliances, lab equipment (ref), and many others.  The size of the plastic industry alone is $2T - and the size of the injection molding industry is about $100B. Between vaccuum cleaners ($1B), consumer 3D printers ($1B),  cordless drills ($1B in the USA alone), drones, phones, cameras - the market size for those goods is on the order of hundreds of billions of dollars worldwide.  The current limit is 20% of GDP - the manufacturing sector of the economy - or about $16T.&lt;br /&gt;
&lt;br /&gt;
The centralized factory can become obsolete, and many parts of global resource flows can become localized. Specifically - as resource constraints to longer fuel resource conflicts and poverty - humans as a whole have - for the first time in world history - a chance for collective evolution. That simply means that the leading preoccupation transitions from making a living, surviving, or paying off debt - to thriving. This means that the multidisciplinary genius will become much more common - as society reaches a new level. An Einstein could be born every minute. (That makes it 1/250 - or 0.4% of the population.) This means that we transcend William Gibson’s — &#039;The future is already here – it&#039;s just not evenly distributed”. This means that most people will gain access to significant improvement in their quality of life. But this is also not a state of coerced equality as in communism - there will always be outliers who are more ambitious or skilled. But all have a good oportunity to thrive. &lt;br /&gt;
&lt;br /&gt;
CNC Torch and Larger Machines: Heavy Duty CNC Machining&lt;br /&gt;
&lt;br /&gt;
==CNC Torch Table==&lt;br /&gt;
&lt;br /&gt;
The universal axis can handle much larger forces - up to one thousand pounds - when it is scaled up. The universal axis has aleady been used with the 3D Printer and the CNC circuit mill. http://opensourceecology.org/wiki/Universal_CNC_Axis   &lt;br /&gt;
&lt;br /&gt;
We have already built a prototype of the CNC torch table using the Universal Axis, scaled up to a 2x3 meter working area:&lt;br /&gt;
&lt;br /&gt;
Fig: CNC Torch Table build workshop results. (https://www.facebook.com/marcin.jakubowski.378/posts/10213076897374250) &lt;br /&gt;
&lt;br /&gt;
The CNC Torch Table is near release status, and it will be the critical machine used in digital fabrication. The CNC Torch table will be used to cut all metal from flat sheets, which are then welded into 3D machines such as the brick press and tractor. The CNC Torch Table will also be used for cutting holes in 4” square tubing - which is our characteristic life-size erector set design.&lt;br /&gt;
&lt;br /&gt;
Typically, acetylene is used as a cutting gas. In the OSE case, the CNC torch table integrates with the oxyhydrogen production - where water is split into hydrogen and oxygen using electrolysis. These hydrogen and oxygen gases are used as the cutting gases. Oxyhydrogen cutting has been in use prior to the discovery of oxyacetylene cutting in 1903 https://en.wikipedia.org/wiki/Oxy-fuel_welding_and_cutting  - and was preferred for 2x the cutting speed with thick metal. Currently, oxyhydrogen is use whenever a clean cut is required. Otherwise, the gas is 2x as expensive as acetylene. The advantages of hydrogen are the ability to cut aluminum and stainless steel, which acetylene cannot do. Furthermore, if the open source oxyhydrogen generator is used with PV electricity at 1.5 cents per kWhr, then the cost of the gas should go down to about 5x lower than acetylene. Given these advantages, it is interesting to see that oxyhydrogen cutting is not used more commonly in the workshop. The apparent reason for this appears to be the lower price of fossil-fuel derived acetylene. Off-shelf on-demand oxyhydrogen generators appear to be expensive, so they would benefit greatly from being open-sourced. https://www.alibaba.com/product-detail/Gas-generation-equipment-for-oxgen-hydrogen_1950398042.html?spm=a2700.7724838.2017115.380.1b0840b43VI2AU  Hydrogen generators which can produce enough gas for cutting ½” steel are  are available for around $300, not including power supply. http://opensourceecology.org/wiki/Oxyhydrogen_Generator_Cost &lt;br /&gt;
&lt;br /&gt;
The OSE CNC torch table system includes a water bed to minimize smoke and prevent steel from warping while cutting, automatic height control which follows the surface of the metal for optimal cutting, an automatic ignitor, automatic gas control, open source controller, and open source controller software. Each of these piecces has been tested separately, and now we are putting the entire system together to a product that from 2018 onwards will be used to cut all steel for OSE in house. We cut steel for frames of the 3D printer, metal for the brick press, tractor, and just about every other GVCS tool.&lt;br /&gt;
&lt;br /&gt;
==Heavy Duty CNC Multimachine==&lt;br /&gt;
&lt;br /&gt;
The CNC Multimachine is a mill, drill, lathe and other tools in one machine, designed for modularity and flexibility, including rotary indexing and a grinding attachments. It can be used to produce engines and hydraulic motors, threaded parts such as bolts and pipe threads, as well as myriad other parts. The lathe has historically been the cornerstone of precision machining, and is a critical tool in civilization.  It is also another application of the OSE Universal Axis system - using the 2” rod size.&lt;br /&gt;
&lt;br /&gt;
Two other GVCS machines - the induction furnace which melts scrap metal to make virgin steel -  and the Mill which makes Rods and Wire - provide feedstocks for the CNC Multimachine.&lt;br /&gt;
&lt;br /&gt;
Fig. The 2” Universal axis can produce parts with accuracy of 10 microns, based on the deflection of 2” rods with 200 lb of force. This image shows the size comparison between the 2” version - and the 1” and 5/16” versions. The belt drive system can be identical to the smaller machines.&lt;br /&gt;
&lt;br /&gt;
We are interested in developing a core set of modules for a heavy duty machine - including mill, drill and lathe, with rotary and angle tables, plus capacity to function as a screw machine for making threads and bolts. We also include internal threads splines. &lt;br /&gt;
&lt;br /&gt;
Just like with the OBI Arch Kit (make sure reference is correct to rapid prototyping above), the Multimachine Construction Set will allow for modeling with 3D printed parts, which will correspond directly to real life - and thus serve as an educational kit and product. Together with the Multimachine Design Guide and FreeCAD workbench, people will be enabled to build their own multimachines and screw machines.&lt;br /&gt;
&lt;br /&gt;
For the 2” universal axis system, the practical limit is 400 lb of tool force with 0.001 precision and GT2 belt drive. For higher tooling forces, we must use lead screws instead of belts.&lt;br /&gt;
&lt;br /&gt;
The goal of the CNC multimachine is to produce electric motors, hydraulic motors, engines, cylinders, and valve blocks, among others. With a grinder attachment, the idea is to be able to achieve high precision, down to 0.0005, which is the positioning accuracy of the stepper motors at 16 microstepping and 1” GT2 pulleys.&lt;br /&gt;
&lt;br /&gt;
Using the Universal Axis, CNC linear motion control, and CNC rotary chuck control - we can get a wide array of functionality of a screw machine for making various precision parts. With a surface grinder, we can get precision parts down to 25 microns of tolerance. If we build a precision CNC surface grinder, then we can achieve up to 1 micron accuracy for making air bearings.https://www.youtube.com/watch?v=sFrVdoOhu1Q  Air bearings open the possibility of lubrication-free engines and high pressure pumps for storing hydrogen and a prerequisite for certain clean-room semiconductor manufacturing.&lt;br /&gt;
&lt;br /&gt;
==Robotic Arm - trainable for welding + 3D printing==&lt;br /&gt;
&lt;br /&gt;
The robotic arm is a powerful manufacturing tool as it is can move almost as flexibly as a human arm - but with increased precision and strength. Practical tasks that a robotic arm can accomplish depend on the end effector or tool that the arm is holding. For the GVCS, two good applications include automated welding and 3D metal printing using a MIG or TIG welder.&lt;br /&gt;
&lt;br /&gt;
Fig. Robotic welding - [nice pic] is useful for high quality welding to assist the open source renaissance woman. Spot welding or wire welding can be used.&lt;br /&gt;
&lt;br /&gt;
A useful application of robotic arms emerges from trainable robotic arms. Trainable robotic arms are arms which a human operator can train to move as needed. This eliminates complex programming tasks, making robotic collaborators accessible to the general public. An open source software platform already exists for robotic arms in the Robotic Operating System (ROS) project, including trainability.http://moveit.ros.org/  - such that the open source trainable industrial robot is around the corner by building on existing prior art. &lt;br /&gt;
&lt;br /&gt;
==Induction Furnace==&lt;br /&gt;
&lt;br /&gt;
An induction furnace is a device use to melt metal.  Metal can then be recycled - from scrap to useful stock. The advantage of the induction furnace over any other means of melting metal is a clean, energy-efficient and well-controllable melting process. In a typical induction furnace, a water-cooled copper coil with alternating current induces a current in a crucible of metal - hence the name Induction furnace - and that current heats up and melts the metal. Due to the heat being generated within the work piece, energy transfer is extremely efficient.&lt;br /&gt;
&lt;br /&gt;
Fig. In an induction furnace&lt;br /&gt;
&lt;br /&gt;
The induction furnace brings us from the stone and wood age - when stone and wood were the most common materials for making houses and machines - into the iron age - which is synonymous with the industrial age and modern civilization.  &lt;br /&gt;
&lt;br /&gt;
It may be said that modern civilization has culminated with the production of ball bearings. Bearings are a critical component that allows for engines, turbines of modern power to work - and precision machines that use precision ball bearings are used to manufacture these machine. Finally,  vacuum pumps and precision instruments - necessary in semiconductor manufacturing - depend on the use of bearings. As such, the information age today also relies on ball bearings - a combination of material science and precision manufacturing.&lt;br /&gt;
&lt;br /&gt;
==Metal Rolling, Rod &amp;amp; Wire Mill==&lt;br /&gt;
The induction furnace can be used in metal casting, where round rods or billets are cast and then used as feedstocks for metal rolling.&lt;br /&gt;
&lt;br /&gt;
Metal rolling uses rolling dies to shape metal into various profiles, from flat, to round, to angled. &lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
Rolling of thin rounds - or rods - around dies and pulleys - is used to elongate and thin the rounds results in wire - a fundamental building block of civilization. Wire is used for house electrical wiring, suspension,  or fencing.&lt;br /&gt;
&lt;br /&gt;
Fig. A wire drawing machine starts from rod and stretches it to wire through a number of dies. The modular open source version can take rod and turn it into wire of any diameter.&lt;br /&gt;
&lt;br /&gt;
Metal rolling that occurs above the crystallization temperature (700C) is called hot rolling - and it takes less energy to do so as the metal is pliable. Cold rolling occurs at room temperature, and therefore requires more energy to deform the metal - but it also provides more accurate dimensions in the metal.&lt;br /&gt;
 &lt;br /&gt;
==Forging, Ironworker==&lt;br /&gt;
&lt;br /&gt;
The press forge is a heavy duty press than can be used to squeeze metal like butter. When metal is hot, it can be deformed into useful shapes by using a die. Bolt heads are made this way.&lt;br /&gt;
&lt;br /&gt;
Forges can take the form of press, drop, or roll rolling - preferably using the induction furnace for efficient forging. Cold forging may also be done, but that requires larger force for a given deformation.&lt;br /&gt;
&lt;br /&gt;
Forging is useful but the disadvantage is using specialized forming shapes or dies. Thus, the preferable route to forging would in many cases be subtractive machining, metal 3D printing,  or welding - as these are general-purpose procedures that do not require custom forms or dies.&lt;br /&gt;
&lt;br /&gt;
Fig. The press forge can shape hot or cold metal like butter.&lt;br /&gt;
&lt;br /&gt;
==Plasma Cutter, Welder==&lt;br /&gt;
&lt;br /&gt;
The plasma cutter, welder, and induction furnace are high-power electronics that use modern technology for efficiency. By using transistors and inverter circuits instead of large transformers, they can be light-weight and low cost - as the cost of power transistors is 10 cents/kW of power handling ability. This means that the simplest welder circuits can cost only a few dollars in electronic components (not counting wiring, structure, and the balance of system) to get industrial welders on the scale of 10kW (500Amps).&lt;br /&gt;
&lt;br /&gt;
Fig. Diagram of a welder. From first principles, a welder includes power handling electronics, wires, a case, cooling fan, and a welding gun with an electrode, and shielding gas for high quality welds.  In the simplest case - a tungsten electrode creates an arc to the metal and melts the metal, without using filler. This is an example of autogenous welding, where no welding rod or wire is required.  Welding is not complicated - the simplest electric arc welder is a 12V battery connected to a welding rod.&lt;br /&gt;
&lt;br /&gt;
A plasma cutter is a transistor-based power electronic device that cuts conductive metals with a plasma - or ionized gas.  The plasma cutter creates ionized air between an electrode and a work piece. The plasma heats the metal. By directing a focused stream of air around that plasma through a nozzle, the heated metal is oxidized and blown away, creating a clean cut. For comparison,  cut quality  in order of improvement is plasma cutting, oxy-fuel, waterjet, and laser cutting.&lt;br /&gt;
&lt;br /&gt;
Fig. Cut width - or kerf - of plasma, oxyfuel, waterjet, and laser cutting.&lt;br /&gt;
&lt;br /&gt;
Both the plasma cutter and welder are similar to each other. They have similar power electronic circuits.  For a welder or plasma cutter, the main difference is in the gun and electrodes. The gun in both cases has a large copper power wire and a gas line for shielding. For the MIG welder, it also has wire feed. The electrode is tungsten for the TIG welder and plasma cutter, and consumable welding wire for the MIG.&lt;br /&gt;
&lt;br /&gt;
More Power Electronics&lt;br /&gt;
&lt;br /&gt;
Is EDM practical? EDM is a high-voltage spark erosion system for cutting thick metals - where a moving wire at 10,000VDC spark-erodes metals as tiny sparks are established between the wire and metal to be cut. This system is insulated&lt;br /&gt;

&lt;br /&gt;
{{ToolTemplate|ToolName=Steam Engine}}&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
=The Development Process=&lt;br /&gt;
&lt;br /&gt;
[[Image:Project-Process.png]]&lt;br /&gt;
&lt;br /&gt;
The product development process consists of the following steps:&lt;br /&gt;
&lt;br /&gt;
# Gather Requirements&lt;br /&gt;
# Create a Design&lt;br /&gt;
# Specify What Will be Built&lt;br /&gt;
# Describe How to Build It&lt;br /&gt;
## Bill of Materials with Sources&lt;br /&gt;
## Fabrication Plan (Diagrams, CAM, CNC, etc)&lt;br /&gt;
## Assembly Instructions&lt;br /&gt;
# Prototype&lt;br /&gt;
# Final Product&lt;br /&gt;
&lt;br /&gt;
The creation of a prototype will often reveal design flaws, hidden assumptions, new requirements, etc.  This learning is fed back into the development process to create a new design leading to another prototype.  When sufficient quality is reached, the product is released (leading to Marketing Plans, User Documentation, Production Plans, and other considerations).&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
=Status=&lt;br /&gt;
&lt;br /&gt;
As of July 20, 2011:&lt;br /&gt;
* Arrowhead Bump Valve design is complete, see [[Steam Engine Design]]&lt;br /&gt;
* Most parts sourced, see [[Steam Engine Bill of Materials]]&lt;br /&gt;
* Dimension specifications and CAD drawings are complete, see [[Steam Engine Build Instructions]]&lt;br /&gt;
* Ready for fabrication and prototyping&lt;br /&gt;
&lt;br /&gt;
Note that in the process of creating the current design, a number of problems have been discovered [http://opensourceecology.org/wiki/Steam_Engine_Reviews/Arrowhead_Bump_Valve_Summary].  Some of these are simple to correct, others may require substantial design changes (valve design, for example).&lt;br /&gt;
&lt;br /&gt;
Other designs are being considered including one based on rotating valves controlled by stepper motors [http://opensourceecology.org/wiki/Steam_Engine_Design/Rotating_Valve] and a return to the Ball Bump Valve Design similar to what was used in the White Cliffs Solar Installation [http://opensourceecology.org/wiki/Steam_Engine_Design/White_Cliffs].&lt;br /&gt;
&lt;br /&gt;
=Progress=&lt;br /&gt;
&lt;br /&gt;
* 2/5/2009 - We are still developing a strategy for building the first steam engine. We have not decided whether we should cast the engine block or approach it by using stock tubing and parts.&lt;br /&gt;
* 4/30/2011 - Project has been re-started based on dialog between Marcin and Mark Norton.&lt;br /&gt;
* 5/3/2011 - Updated design goes into review at SACA.&lt;br /&gt;
* 5/5/2011 - Design review input received from SACA.  Bump valve spring issues lead to consideration of a piston valve control.&lt;br /&gt;
* 5/7/2011 - [[Solar Fire]] absorbed as the official solar concentrator implementation path for OSE - with solar steam engine as the first real-life implementation planned at Factor e Farm for the September [[Factor e Farm Convergence 2011]]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
=Design Questions=&lt;br /&gt;
&lt;br /&gt;
* What kind of steam control valve should we use?&lt;br /&gt;
** Initially, we will use a dual bump valve design.&lt;br /&gt;
* What will be fabbed vs. bought off-the-shelf?&lt;br /&gt;
** See [[Steam Engine Bill of Materials]]&lt;br /&gt;
* What size bore will we use?&lt;br /&gt;
** Four inch bore.&lt;br /&gt;
* Should we enclose the crankshaft for safety and mess-prevention?&lt;br /&gt;
** Probably not at first, later maybe.&lt;br /&gt;
* How do we control oil flow out of the dribbler?&lt;br /&gt;
** Initially gravity flow.&lt;br /&gt;
* How do we handle water condensation in the cylinder?&lt;br /&gt;
** It will be blown out through the exhaust vents.&lt;br /&gt;
* How do we prevent valve springs from annealing and losing their stiffness?&lt;br /&gt;
** Springs will be placed in a hole and protected from high temperature steam.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;

Not sure if there&#039;s a specific page for the [[Translation]] team.  I think there shouldn&#039;t be.  I&#039;m creating it under &amp;quot;others&amp;quot; pending validation by others.  [[User:LucasG|LucasG]] See above under wiki and forum curators. Please fill out [[Team Culturing]] survey - the more we know about you, the more [[Development Process Transparency]]. Start filling in your team members here or request them to do so.&lt;br /&gt;

&#039;&#039;&#039;Note to project managers&#039;&#039;&#039; - This page should:&lt;br /&gt;
* Serve as a one-page master index to all technical development.&lt;br /&gt;
* Each status step should be hyperlinked to provide details.&lt;br /&gt;
* Each step is scored 1-10 for the level of completion.&lt;br /&gt;
* There are 31 steps times 3 prototypes (different colors). That is a total of about 4.5k pages that will eventually be linked to this Status page. To help organize this page, &lt;br /&gt;
* Each tool name should be linked to the [[Product Page Template]]&lt;br /&gt;
** See also [[GVCS tools]]&lt;br /&gt;
** [[GVCS_Organizational_Status]]&lt;br /&gt;
** [[Development Team]]. &lt;br /&gt;
* Development step columns are explained at [[GVCS Development Template]]&lt;br /&gt;

==March 2011==&lt;br /&gt;
Last October I got together the 1 kW concept with the engine configuration, the generator for direct connection to 12VDC system and self regulating steam generator with gravity hopper feed. These things can be published and crowd-funded and the process can be begun at any time. The initial design is next, then the prototype of the engine/generator, then the prototype burner/steam generator, and the system integration. Then development and production prototype can be built. There is material on hand for a thousand units. With that kind of momentum, further materials will not need to be recycled materials but can be economically sustained by normal manufacture.&lt;br /&gt;
&lt;br /&gt;
==Generators in November 2010==&lt;br /&gt;
The basic components selection of the steam genset are being nailed down.&lt;br /&gt;
The F&amp;amp;P based generator is the key engineering component and all else will&lt;br /&gt;
be sized to this element. Therefore I am at the point where the technical&lt;br /&gt;
details are needed so the system can be designed. I believe it would be best&lt;br /&gt;
to design around the newer technology since it is likely to remain available&lt;br /&gt;
longer, but of course if the units are more available with the older&lt;br /&gt;
technology, the design should accommodate them.&lt;br /&gt;
&lt;br /&gt;
We have said that this is a 1kW basic design, and so I would be interested in&lt;br /&gt;
what the speeds, voltage and current are likely to produce 1kW, and also&lt;br /&gt;
what would the number be if driven at your estimated max of 3kW. We have&lt;br /&gt;
been talking about charging 12VDC batteries, and it is possible to simply&lt;br /&gt;
protect against reverse current but not regulate the output except by the&lt;br /&gt;
shaft power going in. Incremental design advances extending to speed control&lt;br /&gt;
for 120VAC 60Hz are not in the initial concept, and I have said that it is&lt;br /&gt;
much better to synthesize the AC from a battery bank anyway. Our burner,&lt;br /&gt;
steam generator, controls and funding plan have been accepted, so we are&lt;br /&gt;
anxious to begin filling in the details.&lt;br /&gt;
&lt;br /&gt;
The next phase is to show the conceptual design with some technical detail&lt;br /&gt;
and credibility to be able to fund the engineering and prototype stage.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;pre&amp;gt;&lt;br /&gt;
&amp;gt; Karl,&lt;br /&gt;
&amp;gt; Yes, I have a written contract with the local F&amp;amp;P manufacturing facility&lt;br /&gt;
&amp;gt; in Clyde, Ohio which is about an hour and a half drive for me. I had to&lt;br /&gt;
&amp;gt; promise that I would not allow my parts to be used as replacement parts&lt;br /&gt;
&amp;gt; for their washing machines. The use as a generator is excellent.&lt;br /&gt;
&amp;gt; Currently they have over eight hundred &amp;quot;seconds&amp;quot; stored for me. I would&lt;br /&gt;
&amp;gt; love to sell them to you. You could not afford to reverse engineer them&lt;br /&gt;
&amp;gt; or even manufacture them at this price. With a five horse motor driving&lt;br /&gt;
&amp;gt; one you can get about 3,000 Watts output, but I believe that would be&lt;br /&gt;
&amp;gt; the maximum. Of course you can scavenge them out of the junk yards, but&lt;br /&gt;
&amp;gt; the washing machines that use these models are very reliable and we&lt;br /&gt;
&amp;gt; won&#039;t see many for several more years. Let me know how many you want and&lt;br /&gt;
&amp;gt; I&#039;ll figure how much discount I can give you.&lt;br /&gt;
&amp;gt;&lt;br /&gt;
&amp;gt; Here is the standard verbage that I usually send in reply to a F&amp;amp;P&lt;br /&gt;
&amp;gt; inquiry.&lt;br /&gt;
&amp;gt;&lt;br /&gt;
&amp;gt; Great News! I have been able to get a shipment of Smart Drive motors&lt;br /&gt;
&amp;gt; directly from the Fisher &amp;amp; Paykel Appliance Motor plant, and yes, I have&lt;br /&gt;
&amp;gt; plenty left. This motor is comprised of a hub, stator, and main shaft.&lt;br /&gt;
&amp;gt; The Stator is stationary and comprised of 36 wound coils. Each coil is&lt;br /&gt;
&amp;gt; wound with 195 turns of 0.053” diameter copper wire, so without&lt;br /&gt;
&amp;gt; re-wiring it can produce some high voltage. The ends of the windings are&lt;br /&gt;
&amp;gt; easily accessible for re-wiring. Since this doesn&#039;t have brushes, when&lt;br /&gt;
&amp;gt; the hub is spun it actually becomes an alternator producing AC current.&lt;br /&gt;
&amp;gt; The new type 4 magnet hub has 48 magnetic poles. I am in love with this&lt;br /&gt;
&amp;gt; new motor. I put one together with a couple of bearings (6005) and&lt;br /&gt;
&amp;gt; bearing holder and spun it by hand and felt almost NO cogg. Price for&lt;br /&gt;
&amp;gt; this raw Smart Drive bundle is $105.00. To make the motor complete, you&lt;br /&gt;
&amp;gt; will need two bearings, (6005 or USF205-25 4-bolt flange bearing), two&lt;br /&gt;
&amp;gt; 12 x 30 mm Bolts, four ¼-20 x ¾” bolts and a bearing holder or pivot&lt;br /&gt;
&amp;gt; weldment. (I now have a new HAWT design available). The Stator normally&lt;br /&gt;
&amp;gt; is piloted off the bearing to align it with the main shaft for the&lt;br /&gt;
&amp;gt; magnetic hub. That bearing (6005) should stick out from .100” to .125”&lt;br /&gt;
&amp;gt; to allow this alignment. I was in the process of developing a “kit” for&lt;br /&gt;
&amp;gt; these motors, but that has yet to materialize. I am willing to “talk”&lt;br /&gt;
&amp;gt; you thru any problems or questions. If you have any questions, please&lt;br /&gt;
&amp;gt; email. More windmill pictures are posted on my web page you can follow&lt;br /&gt;
&amp;gt; this link to www.randysworkshop.com. Shipping weight is approx. 16# from&lt;br /&gt;
&amp;gt; zip code 45306 and can ship Priority Mail for $18.00 to your US zip&lt;br /&gt;
&amp;gt; code. (Over seas estimate is $58.00)&lt;br /&gt;
&amp;gt;&lt;br /&gt;
&amp;gt;&lt;br /&gt;
&amp;gt;         I have seen the price of Ametek motors go from $15.00 six years&lt;br /&gt;
&amp;gt;         ago to over $150.00. And for that you get what? A maximum of 100&lt;br /&gt;
&amp;gt;         to 150 watts? With a SmartDrive windmill and the correct amount&lt;br /&gt;
&amp;gt;         of wind and a good blade you should see upwards of 600 watts.&lt;br /&gt;
&amp;gt;         Yes, this is the way to go!&lt;br /&gt;
&amp;gt;&lt;br /&gt;
&amp;gt; Randy B.&lt;br /&gt;
&amp;lt;/pre&amp;gt;&lt;br /&gt;
&lt;br /&gt;
==November 2010==&lt;br /&gt;
The plan would be to prepare a blog post for next week, say Wednesday or Friday, where we put this project up for crowd funding to pay you for initial design. Then we can discuss the implementation. With a clear plan, we can promise the crowds specific results, and we could get this funded.&lt;br /&gt;
&lt;br /&gt;
At this time, we can move forward on design work, according to specifications we discussed initially.&lt;br /&gt;
&lt;br /&gt;
The general specifications are here:&lt;br /&gt;
&lt;br /&gt;
http://openfarmtech.org/index.php?title=Open_Source_Steam_Power_Generator&lt;br /&gt;
&lt;br /&gt;
Can you prepare a simple concept 3D drawing for the entire system? I was thinking a vertical hopper next to a vertical chimney heat exchanger stack next to a vertical pellet container. That could be a unit plugged into a regenerator.&lt;br /&gt;
&lt;br /&gt;
Perhaps make Prototype I a bulky stationary system with 100% passive fluid motion, and Prototype II with a much more compact form factor - literally like a mobile generator with forced air and forced cooling for a radiator - literally comparable to regular generators.&lt;br /&gt;
&lt;br /&gt;
Let&#039;s work on the technical details at this time. Could we come up with a budget and timeline for the project? Tell me what you need to guarantee your attention on this, and we can put up a funding basket.&lt;br /&gt;
&lt;br /&gt;
Proposed timeline:&lt;br /&gt;
&lt;br /&gt;
1. Blog post - Wed. Oct 27, 2011&lt;br /&gt;
*Concept fleshed out with more details&lt;br /&gt;
*Bill of Materials&lt;br /&gt;
*Realistic time schedule&lt;br /&gt;
*[[Stan Jakuba]] feasibility&lt;br /&gt;
*[[Larry Dobson]] - on heat generator&lt;br /&gt;
*[[Randy Burmeister]] on Fischer Paykel motors&lt;br /&gt;
&lt;br /&gt;
2. Design funding period - Oct 13-Nov. 13&lt;br /&gt;
&lt;br /&gt;
3. Design complete by Dec. 13&lt;br /&gt;
&lt;br /&gt;
4. Fabrication funding period - Dec. 13 - Jan. 13.&lt;br /&gt;
&lt;br /&gt;
5. Build complete by Feb. 13.&lt;br /&gt;
&lt;br /&gt;
Basically, initial proposal with full budget by next week:&lt;br /&gt;
&lt;br /&gt;
1. Design cost&lt;br /&gt;
&lt;br /&gt;
2. Materials cost&lt;br /&gt;
&lt;br /&gt;
3. Fabrication cost&lt;br /&gt;
&lt;br /&gt;
After funding is complete, then we do one month to complete the design, followed by one month of build. Does that sound feasible? First build by Feb. 13.&lt;br /&gt;

=The Development Process=&lt;br /&gt;
&lt;br /&gt;
[[Image:Project-Process.png]]&lt;br /&gt;
&lt;br /&gt;
The product development process consists of the following steps:&lt;br /&gt;
&lt;br /&gt;
# Gather Requirements&lt;br /&gt;
# Create a Design&lt;br /&gt;
# Specify What Will be Built&lt;br /&gt;
# Describe How to Build It&lt;br /&gt;
## Bill of Materials with Sources&lt;br /&gt;
## Fabrication Plan (Diagrams, CAM, CNC, etc)&lt;br /&gt;
## Assembly Instructions&lt;br /&gt;
# Prototype&lt;br /&gt;
# Final Product&lt;br /&gt;
&lt;br /&gt;
The creation of a prototype will often reveal design flaws, hidden assumptions, new requirements, etc.  This learning is fed back into the development process to create a new design leading to another prototype.  When sufficient quality is reached, the product is released (leading to Marketing Plans, User Documentation, Production Plans, and other considerations).&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
=Status=&lt;br /&gt;
&lt;br /&gt;
As of July 20, 2011:&lt;br /&gt;
* Arrowhead Bump Valve design is complete, see [[Steam Engine Design]]&lt;br /&gt;
* Most parts sourced, see [[Steam Engine Bill of Materials]]&lt;br /&gt;
* Dimension specifications and CAD drawings are complete, see [[Steam Engine Build Instructions]]&lt;br /&gt;
* Ready for fabrication and prototyping&lt;br /&gt;
&lt;br /&gt;
Note that in the process of creating the current design, a number of problems have been discovered [http://opensourceecology.org/wiki/Steam_Engine_Reviews/Arrowhead_Bump_Valve_Summary].  Some of these are simple to correct, others may require substantial design changes (valve design, for example).&lt;br /&gt;
&lt;br /&gt;
Other designs are being considered including one based on rotating valves controlled by stepper motors [http://opensourceecology.org/wiki/Steam_Engine_Design/Rotating_Valve] and a return to the Ball Bump Valve Design similar to what was used in the White Cliffs Solar Installation [http://opensourceecology.org/wiki/Steam_Engine_Design/White_Cliffs].&lt;br /&gt;
&lt;br /&gt;
=Progress=&lt;br /&gt;
&lt;br /&gt;
* 2/5/2009 - We are still developing a strategy for building the first steam engine. We have not decided whether we should cast the engine block or approach it by using stock tubing and parts.&lt;br /&gt;
* 4/30/2011 - Project has been re-started based on dialog between Marcin and Mark Norton.&lt;br /&gt;
* 5/3/2011 - Updated design goes into review at SACA.&lt;br /&gt;
* 5/5/2011 - Design review input received from SACA.  Bump valve spring issues lead to consideration of a piston valve control.&lt;br /&gt;
* 5/7/2011 - [[Solar Fire]] absorbed as the official solar concentrator implementation path for OSE - with solar steam engine as the first real-life implementation planned at Factor e Farm for the September [[Factor e Farm Convergence 2011]]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
=Design Questions=&lt;br /&gt;
&lt;br /&gt;
* What kind of steam control valve should we use?&lt;br /&gt;
** Initially, we will use a dual bump valve design.&lt;br /&gt;
* What will be fabbed vs. bought off-the-shelf?&lt;br /&gt;
** See [[Steam Engine Bill of Materials]]&lt;br /&gt;
* What size bore will we use?&lt;br /&gt;
** Four inch bore.&lt;br /&gt;
* Should we enclose the crankshaft for safety and mess-prevention?&lt;br /&gt;
** Probably not at first, later maybe.&lt;br /&gt;
* How do we control oil flow out of the dribbler?&lt;br /&gt;
** Initially gravity flow.&lt;br /&gt;
* How do we handle water condensation in the cylinder?&lt;br /&gt;
** It will be blown out through the exhaust vents.&lt;br /&gt;
* How do we prevent valve springs from annealing and losing their stiffness?&lt;br /&gt;
** Springs will be placed in a hole and protected from high temperature steam.&lt;br /&gt;
&lt;br /&gt;

=Discussion=&lt;br /&gt;
By Marcin:&lt;br /&gt;
&lt;br /&gt;
Personally I am convinced that we can solve the whole transportation emissions question overnight by switching from fossil fuel to biofuel - by adding charcoal gasification to ICE cars so they can run on regeneratively-grown charcoal pellets derived from pelletized biomass. Charcoal pellets are a flowable fuel, and requires minimum car modification such that new cars could ship with this option. Agriculture wise, this can be integrated with perennial polyculture plantings, such as those including hazelnuts and chestnuts (see [[Badgersett Research]]) that can be coppiced to produce fuel in addition to food.&lt;br /&gt;
&lt;br /&gt;
We are developing this option with Open Source Ecology (please see my TED Talk for context, https://www.ted.com/talks/marcin_jakubowski) , based on first principle calculations. Take the case of 380 million gallon [[Fuel Use in the USA]]. Take the area covered by roadways in the USA.&lt;br /&gt;
&lt;br /&gt;
=Calculations=&lt;br /&gt;
==Case 1: Taking out all roads and planting them with perennial polyculture biomass==&lt;br /&gt;
*[[Acreage of Highways]] - 24 acres per mile, or about 1M acres&lt;br /&gt;
*[[Length of USA Roads]] - over 4 million miles, with 48,000 miles of [[USA Interstate Highways]]. If average road is 30 feet wide [https://www.fhwa.dot.gov/publications/research/safety/humanfac/94023.cfm] - that area is &lt;br /&gt;
:*3 acres per mile - so about 14M acres of non-highway roads.&lt;br /&gt;
*Harvest from area of all roads: 15Mx1000 lb = 15B lb.Sustainable harvest biomass yields are 1000 lb per acre per year. This assumes integrated agroecology of perennial agriculture.&lt;br /&gt;
:*Top biomass crops with such as switchgrass are 5 tons/acre [https://en.wikipedia.org/wiki/Biomass], and oil palm is much more.&lt;br /&gt;
:*For sustainable harvest biomass, get 200 lb charcoal/acre, or 3B lb/year - assuming 20% efficiency of charcoal production from dry biomass weight (ie, 5 lb of dry wood turn to 1 lb of charcoal)&lt;br /&gt;
:*Thus, if total USA fuel use is 380 million gallons, or about 2.5B lb - and suply of charcoal is 3B lb for sustainably harvested biomass - then &#039;&#039;&#039;just covering the area of US roads with biomass production yields half the total fuel supply of the USA&#039;&#039;&#039;.&lt;br /&gt;
:**assumes energy per mass of charcoal is equivalent for charcoal and gasoline [ref?], and 1 gallon of gasoline weighs about 7 lb [ref]&lt;br /&gt;
*[https://en.wikipedia.org/wiki/Biomass] wikipedia article states that current biomass energy is 1.4x larger than all human energy consumption.&lt;br /&gt;
*[[Charcoal Yields]]&lt;br /&gt;
&lt;br /&gt;
==Case 2: Using Farmland==&lt;br /&gt;
*There are 922 million acres of farmland in the USA, see [[Stats]], and 922B lb of regeneratively-harvested perennial polyculture biomass crop - and 1/5 of that for charcoal yield - 180B lb - or 90B lb fuel equivalent.&lt;br /&gt;
*Need in the USA is 2.5B lb per year.&lt;br /&gt;
*Therefore - &#039;&#039;&#039;regeneratively-grown biomass can supply 30x all the transportation fuel in the USA. Or - 3% of farmland would have to be augmented to perennial polyculture to yield all the fuel use in the USA. Because it can be integrated with other use, food production can in principle increase if for example coppiced food/fuel crops are used.&#039;&#039;&#039; Compared to batteries, this is regenerative. Batteries aren&#039;t.&lt;br /&gt;
&lt;br /&gt;
Road percentage compared to land area: 1%. And 2% if farmland is considered.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
=Other Calculations=&lt;br /&gt;
David Mackay calculated that If all the cars on a road were powered using biofuels grown on the verge the planted verge would need to be 8km wide. Is this calculation more pessimistic because it is more efficient to use charcoal in gasification compared with converting biomass to make liquid biofuels?&lt;br /&gt;
&lt;br /&gt;
[http://webcache.googleusercontent.com/search?q=cache:8NaTGWOuyqEJ:www.inference.eng.cam.ac.uk/sustainable/blog/PoweringTransport.html+&amp;amp;cd=1&amp;amp;hl=en&amp;amp;ct=clnk&amp;amp;gl=uk]&lt;br /&gt;
&lt;br /&gt;
Richard Patton estimates that it is possible to replace 75% of current diesel use in the USA with sustainably grown charcoal in a charcoal-water slurry fuel for diesel engines.&lt;br /&gt;
&lt;br /&gt;
[http://s3.amazonaws.com/academia.edu.documents/40407983/Coal_vs._Charcoal-fueled_Diesel_Engines_20151126-3871-1ti984z.pdf?AWSAccessKeyId=AKIAIWOWYYGZ2Y53UL3A&amp;amp;Expires=1488236059&amp;amp;Signature=FyjTT3WrXfpdfvnkerZKwT%2Fqwbs%3D&amp;amp;response-content-disposition=inline%3B%20filename%3DCoal_vs._Charcoal-fueled_Diesel_Engines.pdf]&lt;br /&gt;
&lt;br /&gt;
In a Biomass-to-Wheel efficiency analysis, Huang and Zhang estimate that in the longer term, 7% of annual US biomass production could fuel 100% of light-duty passenger vehicle fuel needs with Sugar-Fuel-Cell technology.&lt;br /&gt;

&lt;div&gt;=Overview=&lt;br /&gt;
[[Image:AdCiv3.png‎|thumb|400px|[[Post Scarcity Presentation]]]]&lt;br /&gt;
&lt;br /&gt;
Post scarcity (also styled post-scarcity or postscarcity) is a hypothetical form of economy or society, in which things such as goods, services and information are free, or practically free. This would be due to an abundance of fundamental resources (matter, energy and intelligence), in conjunction with sophisticated automated systems capable of converting raw materials into finished goods, allowing manufacturing to be as easy as duplicating software.&lt;br /&gt;
&lt;br /&gt;
==Post Scarcity Community==&lt;br /&gt;
A post-scarcity community is a community that achieves low work-hour requirement for attaining a modern standard of living, while not participating in any geopolitical compromises whatsoever - as a route to freedom, meaning, and pursuit of happiness - both on the personal and political level. This type of community is marked by transcendence of artificial scarcity that is found in &#039;mainstream&#039; economic paradigms.&lt;br /&gt;
&lt;br /&gt;
==Post Scarcity Production Levels==&lt;br /&gt;
&lt;br /&gt;
Artificial scarcity includes, among others:&lt;br /&gt;
&lt;br /&gt;
#A Prussian-based education system to generate specialized factory workers as opposed to diversified independents&lt;br /&gt;
#Maintaining monopolies on resources and production&lt;br /&gt;
#Guiding human opinions towards particular consumer choices&lt;br /&gt;
#Necessity of warfare for securing material feedstocks&lt;br /&gt;
#Firm police state assistance in maintaining specified patterns of wealth distribution&lt;br /&gt;
#Overspecialization - specialized machines and humans&lt;br /&gt;
#Competitive waste, such as proprietary research&lt;br /&gt;
#Nonstandard components and hundreds of different products with limited coordination of production&lt;br /&gt;
#Dedicated components with little use outside of their specified function&lt;br /&gt;
#Non-customizable products&lt;br /&gt;
#Significant capitalization requirements for startup as a significant barrier fostering monopolization of production&lt;br /&gt;
#Banking procedures that favor support of non-innovative solutions&lt;br /&gt;
#Design for obsolescence, throw-away products, and throw-away society&lt;br /&gt;
&lt;br /&gt;
The above combine to result in production and products that are inferior, short-lived, and inadequate for true human needs. &lt;br /&gt;
&lt;br /&gt;
The remedies for the above, on a point-by-point basis, are: &lt;br /&gt;
#Self-education, online learning, internships, mentorships, or experiential learning&lt;br /&gt;
#Replacing scarce resources with ubiquitous resources, by refining one&#039;s tastes or by using enabling technologies that allows the transformation of ubiquitous resources into services formerly provided by scarce resources&lt;br /&gt;
#Elimination of advertising hype&lt;br /&gt;
#Peace-building by turning to local resources as a means of generating prosperity&lt;br /&gt;
#Wealth distribution is informed by stewardship over resources&lt;br /&gt;
#Generalization - multi-purpose machinery and multi-purpose people&lt;br /&gt;
#Collaboration for open product development&lt;br /&gt;
#Standardized components without reducing functionality, and scalable, modular components&lt;br /&gt;
#Generalized components which can be used in many applications&lt;br /&gt;
#Customizable, scalable, modular, multipurpose products&lt;br /&gt;
#Lowering barriers to entry via low-cost access to equipment and zero access barriers to enabling information&lt;br /&gt;
#Crowd funding, loans from family and friends, access to productive equipment instead of bank papers&lt;br /&gt;
#Lifetime design&lt;br /&gt;
&lt;br /&gt;
The above elements of non-scarcity combine to what is known as abundance - which is a mindset enjoyed by only a small fraction (~1%) of the population. However, as people evolve their index of possibilities to include practical routes towards post-scarcity, as embodied in the GVCS, then the principles of abundance turn into practice.&lt;br /&gt;
&lt;br /&gt;
Post-scarcity production is a level of production attained that is so easy and accessible that it loses its power of control of people over one another.&lt;br /&gt;

=Discussion=&lt;br /&gt;
By Marcin:&lt;br /&gt;
&lt;br /&gt;
Personally I am convinced that we can solve the whole transportation emissions question overnight by switching from fossil fuel to biofuel - by adding charcoal gasification to ICE cars so they can run on regeneratively-grown charcoal pellets derived from pelletized biomass. Charcoal pellets are a flowable fuel, and requires minimum car modification such that new cars could ship with this option. Agriculture wise, this can be integrated with perennial polyculture plantings, such as those including hazelnuts and chestnuts (see [[Badgersett Research]]) that can be coppiced to produce fuel in addition to food.&lt;br /&gt;
&lt;br /&gt;
We are developing this option with Open Source Ecology (please see my TED Talk for context, https://www.ted.com/talks/marcin_jakubowski) , based on first principle calculations. Take the case of 380 million gallon [[Fuel Use in the USA]]. Take the area covered by roadways in the USA.&lt;br /&gt;
&lt;br /&gt;
=Calculations=&lt;br /&gt;
==Case 1: Taking out all roads and planting them with perennial polyculture biomass==&lt;br /&gt;
*[[Acreage of Highways]] - 24 acres per mile, or about 1M acres&lt;br /&gt;
*[[Length of USA Roads]] - over 4 million miles, with 48,000 miles of [[USA Interstate Highways]]. If average road is 30 feet wide [https://www.fhwa.dot.gov/publications/research/safety/humanfac/94023.cfm] - that area is &lt;br /&gt;
:*3 acres per mile - so about 14M acres of non-highway roads.&lt;br /&gt;
*Harvest from area of all roads: 15Mx1000 lb = 15B lb.Sustainable harvest biomass yields are 1000 lb per acre per year. This assumes integrated agroecology of perennial agriculture.&lt;br /&gt;
:*Top biomass crops with such as switchgrass are 5 tons/acre [https://en.wikipedia.org/wiki/Biomass], and oil palm is much more.&lt;br /&gt;
:*For sustainable harvest biomass, get 200 lb charcoal/acre, or 3B lb/year - assuming 20% efficiency of charcoal production from dry biomass weight (ie, 5 lb of dry wood turn to 1 lb of charcoal)&lt;br /&gt;
:*Thus, if total USA fuel use is 380 million gallons, or about 2.5B lb - and suply of charcoal is 3B lb for sustainably harvested biomass - then &#039;&#039;&#039;just covering the area of US roads with biomass production yields half the total fuel supply of the USA&#039;&#039;&#039;.&lt;br /&gt;
:**assumes energy per mass of charcoal is equivalent for charcoal and gasoline [ref?], and 1 gallon of gasoline weighs about 7 lb [ref]&lt;br /&gt;
*[https://en.wikipedia.org/wiki/Biomass] wikipedia article states that current biomass energy is 1.4x larger than all human energy consumption.&lt;br /&gt;
*[[Charcoal Yields]]&lt;br /&gt;
&lt;br /&gt;
==Case 2: Using Farmland==&lt;br /&gt;
*There are 922 million acres of farmland in the USA, see [[Stats]], and 922B lb of regeneratively-harvested perennial polyculture biomass crop - and 1/5 of that for charcoal yield - 180B lb - or 90B lb fuel equivalent.&lt;br /&gt;
*Need in the USA is 2.5B lb per year.&lt;br /&gt;
*Therefore - &#039;&#039;&#039;regeneratively-grown biomass can supply 30x all the transportation fuel in the USA. Or - 3% of farmland would have to be augmented to perennial polyculture to yield all the fuel use in the USA. Because it can be integrated with other use, food production can in principle increase if for example coppiced food/fuel crops are used.&#039;&#039;&#039; Compared to batteries, this is regenerative. Batteries aren&#039;t.&lt;br /&gt;
&lt;br /&gt;
Road percentage compared to land area: 1%. And 2% if farmland is considered.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
=Other Calculations=&lt;br /&gt;
David Mackay calculated that If all the cars on a road were powered using biofuels grown on the verge the planted verge would need to be 8km wide. Is this calculation more pessimistic because it is more efficient to use charcoal in gasification compared with converting biomass to make liquid biofuels?&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
Richard Patton estimates that it is possible to replace 75% of current diesel use in the USA with sustainably grown charcoal in a charcoal-water slurry fuel for diesel engines.&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;I would think &amp;quot;Open Source Ecology&amp;quot; would be about having the Sources of Ecology Open.&lt;br /&gt;
&lt;br /&gt;
Not just the &#039;virtual&#039; Sources such as genetics (DNA) or plans and knowledge about how to raise organisms, what about the [[Physical Sources]]?&lt;br /&gt;
&lt;br /&gt;
Will any part of OSE ever be about Opening the [[Material Inputs]]?&lt;br /&gt;
&lt;br /&gt;
Do we care about insuring access to instances of the designs that have been on the planet for millions of years, or about access to instances of the new designs that are created and opened here?&lt;br /&gt;
&lt;br /&gt;
What if I travel to the OpenFarmTech land in Missouri?  Can I rent land or tools?  Can I become a part owner?  How will such a facility grow?&lt;br /&gt;
&lt;br /&gt;
We need investors.  If those investors are future consumers, they will expect product instead of profit.&lt;br /&gt;
&lt;br /&gt;
Sincerely, -- [[User:AGNUcius|AGNUcius]] 09:55, 25 February 2008 (PST)&lt;br /&gt;

&lt;br /&gt;
Before you read further, please see the [[OSE Mission]]. &lt;br /&gt;
&lt;br /&gt;
OSE Specifications are a way of identifying tools that will allow people to  create abundant local economic production as a basis for community prosperity in an interconnected world. The OSE Specifications are a list of qualities; technologies that have these qualities are technologies that allow people to use their local resource-base to create abundance. Material abundance leaves people with free time and energy to fuel cultural and scientific progress.&lt;br /&gt;
&lt;br /&gt;
These values are to be embodied in the development process, in the recruitment of volunteers, in OSE&#039;s organizational structure and in all operations, public and private:&lt;br /&gt;
&lt;br /&gt;
{{Wanted|Shorten this list and simplify it. A lot of these just repeat other values (In work, see [[Requirements Analysis]]) [[User:DanielRavenNest|DanielRavenNest]] 06:42, 5 May 2011 (PDT)}}&lt;br /&gt;
&lt;br /&gt;
#&#039;&#039;&#039;Open&#039;&#039;&#039; - Open Source Ecology endorses the open-source culture of sharing and collaborative development. This applies to all components of the project: technical design, organizational structure, finances, business and marketing methods etc. Everything we know, you know. We encourage members to collaborate openly, in a culture of respect. We are aiming to create collaboration structures (such as wikis and web forums) to facilitate this open flow of information. We encourage everybody on the development team to be transparent about their work, and to ask openly for collaborative assistance. We encourage everybody to give information away for free – as the cost of sharing information is zero.&amp;lt;br&amp;gt;It is imperative that the technical details of the [[Global Village Construction Set]] tools be published openly on the Internet, with no restrictions, patents or trade secrets. Bills of materials, 3D designs, schematics, build instructions,  and product manuals are to be published on our wiki. This gives the user the power to design, produce, and modify the [[GVCS]] tools according to his or her wishes. The same person is therefore consumer, producer and designer. This leads to robust, tailor-made goods. This allows a global team of developers to improve the tools. &amp;lt;br&amp;gt;Business models should be published openly so that others can replicate any enterprise. We believe it is best to publish plans early and often. This exposes our errors and dead ends to the scrutiny of our online community and leads to faster, better design. We value sharing and collaborative development over greed and exclusiveness. This type of culture promotes co-operation, as opposed to fear-based aggressiveness. &lt;br /&gt;
#&#039;&#039;&#039;Distributive Economics&#039;&#039;&#039; – We believe in decentralizing economic activity. We aim to decentralize the production of food through [[:Category:Food and Agriculture|local food systems]], and decentralize the production of technology by combining local [[Digital Fabrication|digital fabrication]] with global collaborative design to create what we call &#039;[[Industry 2.0]]&#039;.&amp;lt;br&amp;gt;In distributive economics, information should be free because the cost of distributing information is negligible. However, atoms or physical objects are not &#039;free&#039; in the same sense, as significant energy is required to produce and distribute physical goods.&lt;br /&gt;
#&#039;&#039;&#039;Low-Cost&#039;&#039;&#039; - The cost of buying or making our machines are, on average, 5-10x cheaper than buying from an industrial manufacturer-  including an average labor cost of $25 hour for a GVCS fabricator. Commentary: &lt;br /&gt;
#&#039;&#039;&#039;Modular&#039;&#039;&#039; – Components of the GVCS function as interchangeable modules. Motors, parts, assemblies, and power units can interchange, where units can grouped together to diversify the functionality that is achievable from a small set of units. To see how the different parts fit together - see [[Product Ecologies]]. &lt;br /&gt;
#&#039;&#039;&#039;Closed-Loop Material Cycles&#039;&#039;&#039; – As in nature, nothing goes to waste, but instead becomes an input for another process. Our project relies on recycling metal into virgin feedstock for producing further GVCS technologies - thereby allowing for cradle-to-cradle manufacturing cycles. &lt;br /&gt;
{{Wanted|Resolve the clash between &amp;quot;High Performance&amp;quot; and &amp;quot;Sufficiency&amp;quot;}}&lt;br /&gt;
#&#039;&#039;&#039;High Performance&#039;&#039;&#039; - Performance standards must match or exceed those of industrial counterparts for the GVCS to provide a comparable or better standard of living.&lt;br /&gt;
#&#039;&#039;&#039;Sufficiency&#039;&#039;&#039; – We understand that we need to reach a certain level of performance, and that is sufficient. This is distinct from continuous addition of frivolous bells and whistles.&lt;br /&gt;
&lt;br /&gt;
#&#039;&#039;&#039;Ecological Design&#039;&#039;&#039; -  Our products promote a harmonious co-existence between nature and humans. The entire process and technology must fit the criteria for being environmentally friendly and regenerative.&lt;br /&gt;
#&#039;&#039;&#039;Adaptability&#039;&#039;&#039;– The systems that we are designing are designed to be adaptable. This arises from the ability to modify, scale and replicate the components and systems to meet requirement of constantly changing conditions. The tools are useful anywhere - from the 1st to the 4th worlds, from the city to the country, from high technology to low technology applications, at different scales of operation.&lt;br /&gt;
#&#039;&#039;&#039;Systems Design&#039;&#039;&#039; – Our designs consider the whole system of life support, in terms of how the different machines and services interface with one another. Different machines can functions as modules in a wide array of integrated systems. We do not choose technologies with peak point performance, but with peak systems performance as they fit into a resilient community integrated with its natural life support systems. Part of the systems design is synergy – in that the GVCS is intended to attain its maximum potential when all of its components are working with one another.&lt;br /&gt;
#&#039;&#039;&#039;Lifetime Design&#039;&#039;&#039; – Our products are designed for a lifetime of use. Open-source design, where the designer is the user, has no interest in planning obsolescence. Design-for-disassembly, simplicity, transparency, and open-source documentation allows the user to understand, take apart, modify, service, maintain, and fix tools without relying on expensive repairmen.&lt;br /&gt;
#&#039;&#039;&#039;Substitutability&#039;&#039;&#039; – Our products substitute common resources for less common resources. &lt;br /&gt;
#&#039;&#039;&#039;Flexibility&#039;&#039;&#039; – Our tools can be used flexibly in a wide range of applications. Our digital fabrication equipment can flexibly produce a huge variety of products, in contrast with a factory robot that can only produce the same thing over and over again. Our means to [[flexible fabrication]] is the [[open source fab lab]].&lt;br /&gt;
#&#039;&#039;&#039;Simplicity&#039;&#039;&#039; - We design for simplicity without sacrificing performance standards&lt;br /&gt;
#&#039;&#039;&#039;Complete Economy&#039;&#039;&#039; – The work of OSE is intended to be a workable blueprint for a complete economy. Our designs are geared for a  maker lifestyle on the part of community members. This is also known as a neo-subsistence lifestyle – where communities can provide all the requirements of a complete economy, such that trade is only an option, not a necessity. &lt;br /&gt;
#&#039;&#039;&#039;Scalability and holography&#039;&#039;&#039; – The GVCS tools are designed to be scalable to different sizes of operations, from individual households to agglomerations of villages (cities). The design should be holographic, in that each unit of operation should be self-contained (complete) and resilient. With modern technology, human organization can be scaled down to the village scale – empowered by open access to information.&amp;lt;br&amp;gt;We look at the village scale of about 200 people as the optimal scale of human organization for several reasons. First, it&#039;s a historically proven number. Second, it follows [[Dunbar&#039;s Number]] to allow for persistent and meaningful social interaction. Third, it is easily manageable from an organizational point of view without requiring bureaucratic overhead. Fourth, it is sufficiently large to allow specialization via division of labor. Fifth, it allows for a walking- or biking-distance community. Sixth, it is a basic building block - where larger communities may be designed as units of this small scale for the highest possible resilience - as opposed to organization on a larger scale. Seventh, it has been pointed out by the industrial economist, E. F. Schumacher, in his seminal book, [[Small is Beautiful]], that human organization simply breaks down after it reaches a certain scale.&lt;br /&gt;
#&#039;&#039;&#039;Technological Recursion&#039;&#039;&#039; – The flexible fabrication technology also allows producers to produce more complex machines and parts. This allows a local community to, eventually, attain the capacity to produce any technology known to humankind. &lt;br /&gt;
#&#039;&#039;&#039;Local Resources&#039;&#039;&#039; – The GVCS is fueled by local resources, such as water, sunlight, rock and soil. Via technological recursion, these are transformed into useful technology.&lt;br /&gt;
#&#039;&#039;&#039;Community&#039;&#039;&#039; – The GVCS toolset is designed to promote a just, equitable, and life-giving social contract for a community. The tools are designed to be used by a village-scale community, not by individuals. Within this village, there is a social contract based on division of labor, so that the work of each member contributes to the well-being of the whole community. The role of the individual is lifelong learning, stewardship of land and resources and nonviolence. This co-operative arrangement, along with increased freedom from material constraints, promotes connection between people. This reconnection also includes reconnection to one&#039;s true needs, to one&#039;s family, and to the global family of all living creatures.&lt;br /&gt;
#&#039;&#039;&#039;Proven Techniques&#039;&#039;&#039; – We focus on time-proven concepts, techniques, and technologies. All are principles are generally regarded as common, historical knowledge or wisdom learned through eons of civilization. &lt;br /&gt;
#&#039;&#039;&#039;Cross-Disciplinary Integration&#039;&#039;&#039;  – We provide cutting edge practice in so far as they are integrations of knowledge from many fields and disciplines. We value unabashed boundary-crossing and cross-fertilization, drawing from as many cultures, regions, and time periods as possible.&lt;br /&gt;
#&#039;&#039;&#039;New Economics&#039;&#039;&#039; – One aspect of OSE is that it allows for the creation of a resource based economy, where true wealth is based on the value of natural, primarily local resources, where wealth is created from adding value to natural resources by transforming them to human-usable form.&lt;br /&gt;
#&#039;&#039;&#039;Replicability&#039;&#039;&#039; – OSE work is intended to be replicable, self-replicating, and viral. The open-source nature, low-cost, and simplicity of our designs are key to this.&lt;br /&gt;
#&#039;&#039;&#039;Meaning&#039;&#039;&#039; – Technology, when used appropriately, is intended to reconnect one to meaning, and to natural ecosystems. Reconnection to nature can occur from constant interplay between humans and nature, as natural resources are stewarded responsibly to meet human needs by benign processes.&lt;br /&gt;
#&#039;&#039;&#039;Appropriate Automation&#039;&#039;&#039; – We favor automation of repetitive, difficult, dangerous or unrewarding tasks.&lt;br /&gt;
#&#039;&#039;&#039;Long Term Approach&#039;&#039;&#039; – OSE is seeking long-term solutions on the 100 year scale into the future, not band-aids on superficial issues. We are looking at issues for the long haul, with lasting peace and stability for humanity as the goal.&lt;br /&gt;
#&#039;&#039;&#039;Networked model communities&#039;&#039;&#039; – We are interested in creating a network of like-minded communities that follow OSE values, so that cultural exchange can happen between different communities. This is the [[1000 Global Villages]] concept - 1000 villages that serve as model communities and influence the rest of the world in a positive way. &lt;br /&gt;
#&#039;&#039;&#039;Land and Resource Stewardship&#039;&#039;&#039; – Each OSE facility functions as a land steward. Land is not for sale, but is preserved for ever as a permanent site of human heritage and cultural growth. Resources are stewarded so that they improve in quality with time, as opposed to becoming depleted.&lt;br /&gt;
#&#039;&#039;&#039;Iconoclastic Innovation and Transformation&#039;&#039;&#039; – OSE favors iconoclastic approaches which address issues at the root, not symptoms – towards addressing pressing world issues (war, poverty, corruption, distribution of wealth, disease, etc.). We are not looking for mass-culture compromises swayed by political or special interests, but for authentic solutions based on virtues common to all humankind.&lt;br /&gt;
#&#039;&#039;&#039;Absolute Creative Approaches&#039;&#039;&#039;  - We do not promote destroying anything, just creating a better solution that makes the old paradigm obsolete. We have no use for the concept of &amp;quot;enemy&amp;quot;. We do not hate any group or politic, because we are all in this together. We believe in positive psychology, inspiration, and bringing out the virtues in people – by appealing to their absolute creative, transcendent potential for solutions. We do not endorse fear- or punishment-based motivation tactics.&lt;br /&gt;
#&#039;&#039;&#039;Realism&#039;&#039;&#039; - We favor a realistic approach that can be implemented today, not futuristic dreaming. &lt;br /&gt;
#&#039;&#039;&#039;Abundance&#039;&#039;&#039;- We believe that there are abundant resources – minerals, energy, food, water etc. – for everyone, if we use them efficiently and intelligently. We promote social and technological arrangements that lead to abundance, allowing people free time to pursue their happiness&lt;br /&gt;
&lt;br /&gt;
=Methods and Strategic Approaches=&lt;br /&gt;
&lt;br /&gt;
#&#039;&#039;&#039;Distributive Economics&#039;&#039;&#039; - We recognize the challenges of sharing information openly – in that someone else can &#039;steal&#039; an idea and capitalize on it. We address this issue by encouraging people to publish openly, so that prior art makes information accessible to all, and therefore, making information un-patentable and therefore incapable of being appropriated. In order to capture value, we encourage humans to organize around information resource commons, while building in a physical, productive infrastructure to convert information into the substance of modern-day living via benign, industrial processes&lt;br /&gt;
#&#039;&#039;&#039;Notes on Patents&#039;&#039;&#039;. These make sense only in a world based on scarcity. We encourage each community that adopts OSE principles to build complete, open source, economic productivity – where true wealth can be generated easily. In this case, what is the need for patents? If a community can provide all of its needs - then we enter into the concept of sufficiency. State-of-art point technologies that optimize one feature of performance are not necessarily useful for an ecological tool set. We are interested more in overall, or ecological, performance - as opposed to point performance.&lt;br /&gt;
#&#039;&#039;&#039;Creative Approach&#039;&#039;&#039; - There are a number of movements that cater to fears regarding the end of the world or other comprehensive collapse scenarios. Our approach is intended to empower people from a perspective of what is a-priori favorable and benign - whether or not any cataclysm is on the horizon. It is important to underscore that we focus on positive psychology and transcendence, which we favor over an approach based on fear, because fear-based response is not as likely to create long-lasting solutions.&lt;br /&gt;
#&#039;&#039;&#039;Modular, lifetime design&#039;&#039;&#039; – The core of lifetime design is design-for-disassembly and modularity. Design-for-disassembly is synonymous with user ability to &#039;look under the hood&#039; of a certain device. Modules are interchangeable units of functionality.&lt;br /&gt;
#&#039;&#039;&#039;Closed Loop Manufacturing&#039;&#039;&#039; – OSE endorses closed loop eco-industry, where waste does not exist as the waste is turned into feedstock for other processes.&lt;br /&gt;
&lt;br /&gt;
=Components of OSE Specifications=&lt;br /&gt;
{{Wanted|Get rid of this list by merging it into the other lists above}}&lt;br /&gt;
OSE Specifications cover a number of aspects of economically-significant production, covering the development and production aspects:&lt;br /&gt;
&lt;br /&gt;
*Economic significance&lt;br /&gt;
*Open documentation&lt;br /&gt;
*Distributive economic nature&lt;br /&gt;
*Transformative nature of enterprise&lt;br /&gt;
*Systems design&lt;br /&gt;
*Transparency and participatory nature of production model and development process&lt;br /&gt;
*Creation of post-scarcity levels of production&lt;br /&gt;
*Simplicity and low cost&lt;br /&gt;
*Lifetime, modular design; design-for-disassembly; design-for-scalability &lt;br /&gt;

**Startup Assistance&lt;br /&gt;
&lt;br /&gt;
* Resources (e.g. land) needed for the tool should be locally available&lt;br /&gt;
* The need the tool meets should be essential to a large market. No specialist goods or luxuries.&lt;br /&gt;
* Provision of a robust village economy and sufficient surplus for further developments&lt;br /&gt;
* Generative nature of the product, thus promoting self-replication of the village&lt;br /&gt;
* The GVCS tools together should cover every essential service for a village.&lt;br /&gt;
* Viability of a community on a village scale, perhaps 100 people, but as few as 2 or as many as sustained by the land base&lt;br /&gt;
&lt;br /&gt;
==Economic Significance==&lt;br /&gt;
&lt;br /&gt;
Economic significance refers to the overall economic importance of a given product or service. The assumption here that economic significance is defined on the basis of relevance for meeting the material needs of humans. For example, fuels and tractors constitute multibillion dollar global markets, and are thus economically significant. On the other hand, plain discussion may have little economic significance, if is not more than hot air.&lt;br /&gt;
&lt;br /&gt;
==Open Documentation==&lt;br /&gt;
&lt;br /&gt;
===Readily accessible or downloadble documentation and design===&lt;br /&gt;
&lt;br /&gt;
Distributed information in the computer age is made most readily accessible if it is available for immediate download from the internet. If material is available in electronic format, it may be manipulated or utilized readily with software tools. For example, digital designs may be edited or used immediately in CAD or CAM. If CAM formats are available, then data at one point in space can be readily transformed into a physical object at another point in space, in the presence of digital fabrication capacities.&lt;br /&gt;
&lt;br /&gt;
===Design Drawings===&lt;br /&gt;
&lt;br /&gt;
This is a start towards replicability.&lt;br /&gt;
&lt;br /&gt;
===Bill of Materials (BOM)===&lt;br /&gt;
{{Wanted|Move this section to [[Product Template]]}}&lt;br /&gt;
Next to design drawing, the BOM is the second most important towards replicability. This is a detailed listing of all parts used, sourcing, and prices. Relevant comments should be made alongside the BOM, such as, quality or reliability of certain vendors, their quality of service, and any other useful comments. The only difficulty with a BOM may be that if the audience is global, sourcing may not be readily available or shipping may be prohibitive, so local substitution of parts must be made. If a BOM is available, then the building of a specific product can commence immediately: there is no guessing which parts would work, or which supplier is reliable. At best, the process for one-off individual production can be as follows:&lt;br /&gt;
#an individual decides that they need a certain product&lt;br /&gt;
#they look that product up on an online repository of open source products, download fabrication procedures and parts lists&lt;br /&gt;
#purchase parts locally all on the same day if they are located in an urban area where many suppliers are available&lt;br /&gt;
#and start building a certain project.&lt;br /&gt;
All these steps can potentially be completed in one day when the BOM is available. Open design drawings and plans are only one aspect, but the critical point to enabling immediate production is the availability of BOMs, as the last step prior to actual fabrication.&lt;br /&gt;
&lt;br /&gt;
A possibility then emerges that a large number of people can stop buying goods from who-knows-where and begin to fabricate them locally. This is feasibile on the individual level for anyone equipped with a robust Fab Lab, or when small groups (a few to a dozen people) get together to purchase low-cost, open source, digital fabrication equipment. These people could operate out of backyard garages, rented workshop spaces, co-working facilities, or other community supported manufacturing operations. The types of products that yield themselves particularly to this type of production are those items that fall beyond the class of disposable goods, and are more or less long-use items. These items include electronics, mechanized tools, semi-heavy machinery, green vehicles, renewable energy systems, among others.&lt;br /&gt;
&lt;br /&gt;
====Tools====&lt;br /&gt;
[[CAD by Mariano Alvira]] and [[SKDB]] are two different tools that can improve and automate different aspects of handling a BOM.&lt;br /&gt;
&lt;br /&gt;
===Free information===&lt;br /&gt;
&lt;br /&gt;
If information is free, it is most easily accessible.&lt;br /&gt;
&lt;br /&gt;
==Distributive Economics==&lt;br /&gt;
&lt;br /&gt;
Distributive economics refer to economic models that tend to distribute economic power as opposed to monopolizing this power.&lt;br /&gt;
&lt;br /&gt;
==Transformative Nature of Enterprise==&lt;br /&gt;
&lt;br /&gt;
We are interested in transformative economics, or those economics which tend towards community and global resilience, while having qualities that, proactively, move the world away from: concentration of societal power; perennial warfare; loss of meaning; bureaucracy; globalization of economic activity; [http://en.wikipedia.org/wiki/Newspeak newspeak]; loss of freedom; and so forth.&lt;br /&gt;
&lt;br /&gt;
==Systems Design==&lt;br /&gt;
&lt;br /&gt;
Systems design refers to design of economic paradigms which consider the whole human and natural ecosystem, and the relationships involved, not just an isolated part of that system. For example, non-systems thinking may lead one to conclude that a modern steam engine for transportation is a bad idea compared to biodiesel or fuel alcohol because the thermodynamic efficiency of a steam engine is two times lower than that of diesel engines or gasoline engines. The systems design perspective will claim that the steam engine is a great idea, because biomass pellets can be used as fuel, and the yield of cellulosic biomass per acre is about 10 times higher than the yield of oil or alcohol. The systems thinker will continue, by stating that if the whole system is considered, biomass pellet production is much simpler to accomplish, and that biomass-growing areas can be integrated with other uses such as orcharding or livestock raising, and the systems thinker will continue to make other claims that such an energy source allows for absolute decentralization of production and resilience of communities using the simplest means possible. The point to be made is that the systems thinker can continue to make a large number of claims on how a particular activity is desirable based on a number of systems connections, which the non-systems thinker dismisses as simply not being part of the question.&lt;br /&gt;
&lt;br /&gt;
We believe that destructive non-systems thinking is so pervasive in our society, that in general, individual and societal decision-making is completely partisan, thin on logic, and downright retarded. We are including a metric for systems design in the OSE Specifications to raise awareness of this issue, with a hope, which even if futile, attempts to bring a glimmer of light to the situation.&lt;br /&gt;
&lt;br /&gt;
===[[Systems Engineering]]===&lt;br /&gt;
&lt;br /&gt;
This is the engineering discipline devoted to the entire life cycle of a complex man-made system.  This is distinct from specialty disciplines such as mechanical or electrical engineering which are devoted to specific elements of a system.&lt;br /&gt;
&lt;br /&gt;
==Transparency of Production Model and Development Process==&lt;br /&gt;
&lt;br /&gt;
The development process for products, and their production model, should be transparent to any interested observer. This allows for study of, input into, and improvement of the topic of interest. Transparency allows feedback loops to become active, and empowers those who are interested in learning more about a topic. Transparency is one of several qualities of a distributive, economic process. &lt;br /&gt;
&lt;br /&gt;
Transparency of some program implies that the program is open to suggestions, correction, or replication of itself, stemming from an ethical foundation of the given program. Therefore, tools such as non-disclosure agreements, patents, trade secrets, and other means of protectionism are inconsistent with the creation of transparency.&lt;br /&gt;
&lt;br /&gt;
===Development Process===&lt;br /&gt;
&lt;br /&gt;
1. Participation in the development process is entirely voluntary. No compensation for alienation is necessary. As a result, the best designs are produced from the commitment of passionate stakeholders.&lt;br /&gt;
&lt;br /&gt;
2. Anyone may join or leave the development group at any time&lt;br /&gt;
&lt;br /&gt;
3. Collaborative development process utilizes the input of diverse stakeholders&lt;br /&gt;
&lt;br /&gt;
4. Steps and results of the development process are documented&lt;br /&gt;
&lt;br /&gt;
==Creation of Post-Scarcity Levels of Production==&lt;br /&gt;
&lt;br /&gt;
Post-scarcity levels of production imply the availability of effective tools of production, including both hardware and techniques - which allow for the ample meeting of human needs. Post-scarcity levels of production also imply that local, nonstrategic resources can be utilized effectively, reliably, and with the capacity to produce significant surplus. The goal of attaining post-scarcity levels of production of something are thus synonymous with a particular community being able to transcend physical survival as a basis for evolving to pursuits beyond mere survival.&lt;br /&gt;
&lt;br /&gt;
==Simplicity and Low Cost==&lt;br /&gt;
&lt;br /&gt;
The design and implementation of any product or service should be the simplest from both the fabrication and cost perspective, such that it is the most readily replicable. Attaining simplicity is indeed the most difficult design challenge. Most people confuse high performance with extra features, because they externalize the hidden liabilities that accompany the extra features. Simplicity is synonymous with efficient resource use. Simplicity should also apply to the fabrication procedure of an object. As such, simplicity is also synonymous with low cost. The basic design philosophy of OSE is to include simplicity in design and fabrication - ie, design-for-fabrication should be applied.&lt;br /&gt;
&lt;br /&gt;
==Lifetime, Modular Design; Design-for-Disassembly; Design-for-Scalability (DfS)==&lt;br /&gt;
&lt;br /&gt;
(Note: For mainstream reference on lifetime design, see the work of [[Saul Griffith]])&lt;br /&gt;
&lt;br /&gt;
Simplicity of design promotes the features of lifetime, modular, and scalable design-for-disassembly (DfD). &lt;br /&gt;
&lt;br /&gt;
Lifetime design implies that the value of a product does not depreciate over time. This implies freedom from labor required to replace a certain product, which has direct implication for one&#039;s access to free time.&lt;br /&gt;
&lt;br /&gt;
Modular design is a design which allows different modules to be used and interchanged, giving the user control over and flexibility with the object of use.&lt;br /&gt;
&lt;br /&gt;
DfD means that parts of modules may be replaced readily, by taking the module apart. This has profound implications to lifetime design.&lt;br /&gt;
&lt;br /&gt;
DfS is more than a design that can be scaled. It is the principle of designing things with ease of scalability as one of the features - ie, design that can be scaled easily. This is a slight improvement over design that can be scaled, in that DfS includes explicit features that make scalability easy. &lt;br /&gt;
&lt;br /&gt;
Scalability means that a basic building block can be used to make larger or smaller versions. This contributes to low cost and efficiency.&lt;br /&gt;
&lt;br /&gt;
===Multipurpose Modular Design===&lt;br /&gt;
&lt;br /&gt;
Objects should be designed so that they are made as building blocks, or modules, of other or larger objects. This way, objects can be modified. Instead of a whole object having to be replaced to add new functionality, a module may be added. This gives products a flexibility that is built into their very nature, such that the user has additional control with minimum expense. Modularity may sometimes be synonymous with inter-operability, and may sometimes be synonymous with scalability. It may contribute to lifetime design if an object is 100% modular and each module may be replaced. Modularity also means that an object may function as a building block of other objects. In all cases, modularity implies that an object may be modified. The combination of flexibility, adaptability, scalability, interoperability are desirable. These features expand the range of applications, increase lifetime, reduce cost, as well as provide and retain high value. In a material world, these are features that contribute to wealth and prosperity. In a nutshell, modularity provides large value and has low associated costs. These are good implications for individual and community well-being.&lt;br /&gt;
&lt;br /&gt;
If modular design is followed, then the type of interoperability of using building blocks leads us to a [[Pattern Language]] of technology. In this pattern language, the modules or building blocks serve as the sentences of a larger language, or technology infrastructure.&lt;br /&gt;
&lt;br /&gt;
===Scalability===&lt;br /&gt;
&lt;br /&gt;
Products should be designed so that they can be scaled up or down - such as by addition of new modules, or using multiples of a part in parallel. For example, a solar concentrator system designed according to the principle of scalability should be a linear design (see [[Solar Power Generator]]), so that it could be enlarged either by lengthening or widening the array.&lt;br /&gt;
&lt;br /&gt;
==Localization of Material Sourcing and of Production==&lt;br /&gt;
&lt;br /&gt;
For community resilience, ability to use local resources is key. While it is important that a community have this ability for essential needs, it is optional, though desirable, for other nonessential items.&lt;br /&gt;
&lt;br /&gt;
Using local resources may necessitate that a given community have additional technology to produce a certain item. For example, if a given community does not have the conditions to grow a certain crop easily, it may want to invest in the additional technology required to grow that crop successfully. Or, if a certain community does not have adequate water, it should invest in well-drilling or roof-catchment technology, instead of importing water from unsecured sources.&lt;br /&gt;
&lt;br /&gt;
A community should thus, in general, strive to increase its technology base to accommodate the provision of all essentials, and not settle on its ability to trade to procure these essentials, as trade may be vulnerable to disruption. Trade is quite acceptable for non-essential items, such as musical instruments, since disruption of such supply does not threaten the survival of a community. The level of technology in which a community is autonomous should be determined on practical grounds.&lt;br /&gt;
&lt;br /&gt;
Moreover, in today&#039;s world, we already hear about &#039;produced locally.&#039; We should add &#039;sourced locally&#039; to our vocabulary - as resilience implies not only local production, but also local sourcing. Local sourcing typically requires that a community have additional technological infrastructure and knowhow for providing the necessary feedstocks.&lt;br /&gt;
&lt;br /&gt;
===Localization Levels===&lt;br /&gt;
&lt;br /&gt;
*Level 1 - production is local&lt;br /&gt;
*Level 2 - sourcing of materials used in production is local&lt;br /&gt;
*Level 3 - raw material production is local&lt;br /&gt;
*Level 4 - production machinery used in the production process above is open source and locally fabricated&lt;br /&gt;
&lt;br /&gt;
Localization applies to the creation of natural economies, or those economies based on the substance of their own, natural resources, free of supply chain disruptions.&lt;br /&gt;
&lt;br /&gt;
An example of Level 3 is that local aluminum is made by smelting aluminum from local clays.&lt;br /&gt;
&lt;br /&gt;
If localization is taken to all the 4 levels, for all necessities of sustaining its population - that means that a region is autonomous, and as such, has no built-in tendency to wage war for others&#039; resources. This is the &lt;br /&gt;
critical point of localization - its benign effect on global geopolitical struggle. In simple words, people don&#039;t kill and steal.&lt;br /&gt;
&lt;br /&gt;
==Ecological Qualities==&lt;br /&gt;
&lt;br /&gt;
The product of interest must be good for the environment.&lt;br /&gt;
&lt;br /&gt;
==Economic Feasibility and Replicability==&lt;br /&gt;
&lt;br /&gt;
===Minimization of Waste, Overhead, and Bureaucracy===&lt;br /&gt;
&lt;br /&gt;
The key point to the competitiveness of agile, open source enterprise is its lean structure with minimal overhead. Minimization of waste occurs by collaborative development, such that R&amp;amp;D costs are shared by a number of stakeholders. Competitive waste is eliminated by open enterprise giving services away rather than competing for market share, which is the ethical marketing strategy for open enterprise.&lt;br /&gt;
&lt;br /&gt;
Other strategies for keeping overhead low are [http://blog.opensourceecology.org/?p=391 crowd-funding the production facility], such as in Factor e Farm&#039;s case. We also propose paperwork reduction by operating as an un-incorporated entity, with contractually-based fiscal fiduciaries and liability management, operation in the Republic via private contract, and by in-house legal literacy.&lt;br /&gt;
&lt;br /&gt;
===Product Evolution===&lt;br /&gt;
&lt;br /&gt;
A process should be in place for continued maintenance and development of a product. This could be a support community, foundation, or users.&lt;br /&gt;
&lt;br /&gt;
===Fabrication Facilities===&lt;br /&gt;
&lt;br /&gt;
Concrete Flexible Fabrication mechanism exists for others to purchase the product at reasonable cost. This is a means to assuring that a diversity of suppliers exists, such that monopoly is avoided.&lt;br /&gt;
&lt;br /&gt;
===Open Franchising or [[Open Business Model]]===&lt;br /&gt;
&lt;br /&gt;
This point defines how easily one can obtain access to replicable enterprise design. See our motivation with respect to Open Business Models, as described under the [[OSE License]].&lt;br /&gt;
&lt;br /&gt;
There is a number of details that goes into enterprise replications. These are all the standard details found in a [[Business Plan]], plus the actual technical details that go into that plan, such as designs and CAD, fabrication procedures, BOM and sourcing information, economic analysis, ergonomic analysis, and so forth.&lt;br /&gt;
&lt;br /&gt;
If you are interested in replicating an enterprise, then please inquire with us regarding practical considerations. For those interested in replication, we are looking for long-term commitment to provide the necessary due diligence of business model documentation.&lt;br /&gt;
&lt;br /&gt;
===Startup Assistance===&lt;br /&gt;
&lt;br /&gt;
Producer training is the key to assisting others to start up enterprise. Dedicated workshops should be available for others to learn the trade. We plan on offering a 2 year immersion program, which includes not only workshop skills, but agriculture, as well as theoretical and organizational aspects.&lt;br /&gt;
&lt;br /&gt;
=Calculation of a Metric Score=&lt;br /&gt;
&lt;br /&gt;

=Summary=&lt;br /&gt;
In summary, we aim to raise the standards embodied in open source product development efforts by articulating the possibilities. OSE Specification describes all the desirable features that can be embodied in open economic development, under the assumption that maximum advancement of distributive production is the best route to human prosperity.&lt;br /&gt;
&lt;br /&gt;
OSE Specifications, as applied to technology - imply &#039;&#039;liberatory technology&#039;&#039; - defined as technology which serves the true needs of people and liberates time for other pursuits beyond survival. This is distinct from technology which controls people - where in today&#039;s world - with ever-advancing technology, people enjoy less free time.&lt;br /&gt;
&lt;br /&gt;
=Application of OSE Specifications to Assessing the Liberatory Potential of Technologies=&lt;br /&gt;
OSE Specifications, when applied to production of physical products, allow for transparent assessment of the overall openness or accessibility of &#039;&#039;so-called&#039;&#039; open source products. This specification is intended to help people assess distributive production aspects of projects, by distinguishing between the various degrees of ‘opensource-ness’ embodied in projects. This is because some projects call themselves ‘open source’ when only a small portion of the hardware, or even no physical portion, is open source. &lt;br /&gt;
&lt;br /&gt;
For example, in the case of the [http://green.autoblog.com/2007/10/16/autobloggreen-qanda-open-source-green-vehicle-project/ OS Green Vehicle], the only open source component is an apparent design process, but the output of the design process is proprietary. As quoted from the website, ‘Your rights to use, modify and re-distribute any data from this web site are limited.’ Moreover, the components used in the car are proprietary. Therefore, the OS Green Vehicle has a low OSE Specifications metric score.&lt;br /&gt;
&lt;br /&gt;
Access refers to use for both private or market purposes. The specification is not neutral in its goals, just as no technologies are ever neutral. The intent goes so far as to point out the nuances that contribute to a particular direction of: (1), promoting ecological integrity, (2), contributing to the highest possible quality of life, and (3), creating the widest possible distribution of wealth. Because the open source method of product development has immense potential in transforming the economic system, the OSE Specification aims to address the evaluation of positive change endorsed by various open source projects. &lt;br /&gt;
&lt;br /&gt;
The scope of OSE Specifications is far-reaching: it considers all the steps necessary for a product to be user-accessible. This includes open access to relevant information and affordable access to physical products. The goal is distributive economics.&lt;br /&gt;
&lt;br /&gt;
OSE Specification stipulates access to physical production facilities that can build wealth in re-localized communities. But OSE Specifications go even further: replication and viral spread of wealth - or distributive production. OSE Specifications address the means for replicating the production process itself. This includes not only self-replicating machines and systems, but the development of open business models, training materials, and apprenticeships for entrepreneurs. As the final step, we consider the availability of capitalization assistance within the metric. The capitalization assistance may be part of a new entrepreneur&#039;s apprenticeship - where, for example - real products can be made and sold within the apprenticeship. We redefine the &#039;capital&#039; in &#039;capitalization assistance&#039; from &#039;money&#039; to &#039;the ability to produce just about anything required for business startup at low cost.&#039;&lt;br /&gt;
&lt;br /&gt;
Such level of commitment to the success of replication may imply a hidden agenda behind this program. Indeed there is: the greatest possible empowerment of people and communities to be the masters of their destinies, by unleashed human productivity fueled by open access to information and enabling hardware.&lt;br /&gt;
&lt;br /&gt;
OSE Spec addresses access to both producers and users - both on the individual and community scale. Production could occur by do-it-yourself means on the individual scale in flexible fabrication facilities. The community scale promotes division of labor, and therefore a high standard of living. The OSE Spec addresses the availability of blueprints or digital designs, which can be used readily in manual or automated, computer-controlled fabrication facilities.&lt;br /&gt;
