*'''Introduction''' - CEB - compresssed earth block - regarded as the highest quality natural building method; also used in upscale housing; does not require curing - so may be built continuously; lends itself to 100% onsite building material sourcing; excellent thermal, acoustic, and strength; aka structural masonry. Also usable in fences, cisterns, road paving, Usable for ovens in a bakery, pond dams, thermal storage cisterns, silos. Used for barns, dairy plant, bakery building, additinal housing, greenhouses, etc. I would go so far as that could be the secret weapon of the entire operation. Other connections in diagram: requires soil to be pulverized, which may be done with the agricultural spader. May be used for building raised beds, modular building and greenhouse units. High value flex fab enterprise opportunity for any entrepreneur interested in fabrication of machine- huge profits are possible, because other CEBs are expensive ($25k for one of 3-5 brick/minute performance). Livelihood opportunity for independent builders. Requires as little as 1 person to operate. OSE design is based on power from tractor hydraulics - where the tractor is a general tool that can supply power to a large number of devices. Output with 2 people - a 6 foot high round wall, 20 feet in diameter, 1 foot thick, can be built in one 8 hour day. Fabrication is absolutely simple - after metal is cut - only a drill press is required. Zero welds in structure. Summary: a high performance, rapid, semi-skilled building technique, which lends itself as a building method for creating advanced civilizations. DfD, lifetime design.

This OSE Product Development Cycle is:
{{GVCS Header}}


#Assemble a core development team for each product. This team must serve the functions of: (1), social enterprise website development and fundraising management; (2), technical development; (3), strategic development; (4), review team.
=Overview=
#Publish Ecological Review on website. This review introduces the product of interest and all its attributes, and requests feedback on product choice for meeting a particular service. For example, for renewable energy production, the boundary layer turbine with solar concentrators is considered. In this technology choice, we propose a certain set of deliverables, and challenge the audience to come up with a better solution based on ecological design and localization agendas. We provide the Ecological Review as a motivation for certain products, which is our marketing effort to attract stakeholders to our technology choice. After considerable review, we believe that our product choices represent the best available technology for meeting certain needs, as supported by the Product Selection Metric in this proposal, and as motivated by ecological features, ease of replicability, and localization potential.
 
#Beyond the Ecological Review we define the Product Specifications of the Deliverable. This fills the clear deliverables requirement of Fig. 14. This includes a timeline and budget for product delivery.
[[File:Machine.jpg|right|400px|thumb|CEB Press (aka "The Liberator"). See [[CEB_Press_6#Instructional_Files]] for detailed pictures of the latest machine build (v6), and for an exact picture of v6. Version shown is v3.]]
#Next, we produce a Design, BOM, Sourcing Information, and Fabrication Procedure. This is published on the enterprise website.
[[File:Liberator_bricks.JPG|right|400px|thumb|Bricks pressed on [[The Liberator]]]]
#We then send the information from step 4 out for review. The first level of review is a technical review team. This team of about 5 qualified people reviews the (1) technological aspects, (2), social merit, (3), P2P economy effects, (4) Quality of Life merit, (5), merit from the standpoint of liberatory technology if production time is counted , (6) ecological and regenerative merit, (7), dissemination and replication potential. The results of this review process are then sent out to an external, distributed review team, to verify whether the technical expert opinion holds merit with non-experts in any of the fields.
 
#Three bids are requested from prospective fabricators for prototype fabrication after the design has been agreed upon.
The Liberator is OSE's automatic, high throughput Compressed Earth Brick Press. It is named The Liberator because it is intended to free people from the single highest cost of living - housing. See [[Cost of Living]].
#Now the fundraising cycle proper begins. The first step is to recruit a fundraising team. This team of 10 or so individuals who will lead a publicity effort to direct others to our social enterprise site to request funding. We are looking for a large number of stakeholders to share the development risk, with small donations, and a possible funding collection tool such as Fundable.org.
 
#The role of the fundraising team is to identify potential stakeholders, contact them, and direct them to the website. We propose a week of conscientious fundraising by this team to collect the necessary funding. After 1 week, progress will be evaluated to update fundraising strategy. Details of disbursement upon successful funding are determined on a project-by-project basis, and are to be documented in the deliverable definition (step 3).
The CEB is at product release status and is being actively manufactured at Factor e Farm. The presses was used heavily as a part of the [[Factor e Farm Infrastructure Buildout 2011]]. Builds using the OSE CEB ress continued with the [[Microhouse 1]], [[Microhouse 2]], [[Microhouse 3]], and [[MicroHouse 4]] built in 2014 - [http://www.prweb.com/releases/2015/01/prweb12440135.htm]. We have also built a utility room brick floor and an 8' wall section out of CEBs in the 2016 build of the [[Seed Eco-Home]].
#After a successful funding cycle of approximately 1 month, the building of a prototype (or other deliverable) is funded and product is delivered to Factor e Farm.
 
#The funding cycle is repeated for every step of the product development process. The step after an initial prototype is product testing. This may require certain infrastructure or outsourced testing procedures, and if costs are associated, this step will cover them.
In 2020, we did a [[CEB Microhouse Build in Belize]].
#The next funding iteration is to deploy an optimized prototype. This includes any redesign, and involves the fabrication of an entire device, from gound-up if needed, to document the ergonomics of optimized production.
 
#The next iteration is to deploy an optimized fabrication facility. This is probably the major cost step for all the technologies, unless the infrastructure and machining requirements are already satisfied by the existing flexible fabrication capacity at Factor e Farm. The goal is to have optimal production capacity for several or all of the products being fabricated at the same time.
The bill of materials cost of the current, fully-automated machine is about $5000 US. See [[CEB Press#BOM]].
#Factor e Farm will provide an in-house fabricator (person) at the outset of a particular production effort. New people will be absorbed into the operation as soon as possible so that the Factor e Team could proceed to other products. This requires preparation of training materials and training time for the new participants.
 
#After a fabrication facility is tested, production results are replicable, and quality control requirements are met, optimizations are made to the production facility itself. This may include installation of additional equipment or reorganization of the work space.
The machine can also be made as a manually-controlled version with hydraulic valves. Other options are:
#Once step 14 is complete, production can begin in full. Orders may be accepted and filled at this point.
*small or large hopper
*with or without hopper shaker
*automatic controller at 6-10 bricks per minute, depending on power unit

The buyer is encouraged to brind additional people to the build event to learn about the machine.
 
A tractor loader is used to provide approximately 2 cubic yards of soil per hour at at 6 block per minute pressing rate. A tractor loader is needed to keep up with the machine throughput. Approximately 3 people are required to keep up with the machine for stacking the block upon pallets. Approximately 30 people would be required to load the machine manually with shovels and buckets if no tractor loader were available. At the minimum, 4 people (1 tractor operator, 3 stackers) are required to produce palletized block on an all-day basis.
 
==Specifications of the Standard Model==
*Block is plain block, not interlocking. Please see discussion on [[Interlocking_bricks]]
*Version 17.08 is our most current model. See [[CEB Press Genealogy]] for past versions.

The CEB Press takes earth/dirt/soil and compresses it tightly to make solid blocks useful for building. Compressed earth blocks have many advantages as a building material: by making the building materials from the readily available dirt on the building site, they eliminate the need to transport bricks from elsewhere, reducing financial cost and environmental impact. Compressed earth blocks are very strong and insulate well against both heat and sound, making for very energy-efficient building (especially combined with the energy savings from not needing to transport them from offsite). Best of all, the material they use is already on-site and does not need to be purchased -- quite literally, dirt-cheap!  See the wiki page on [[Compressed Earth Blocks]] and the [[:Category:CEB|CEB category]] for more details on building using CEBs.
 
The Liberator has been fully designed and tested by the [[Open Source Ecology]] team.  Because the Liberator is an open source technology, you can freely download instructions to build your own from materials you can obtain yourself, or contact ''opensourceecology[at]gmail[dot]com'' to buy a kit or a finished machine.
 
Building a machine yourself might seem intimidating, but every step of the process is fully documented and the OSE community is available on our [http://forum.opensourceecology.org/ discussion forums] if you need help, advice, or a little hand-holding.
 
Using the CEB Press, two people can build a 6 foot high (1.83m) round wall, 20 feet (6.1m) in diameter, 1 foot (30cm) thick, in one 8 hour day, though construction time will vary somewhat depending on preparation time, what equipment is available (tractor to prepare the ground and move the blocks where they need to go), the quality of the soil, and other factors. The bigger the block size, the faster a wall can be erected, but at the cost of heavier blocks that are more of a strain to work with.  Blocks from ''The Liberator'' average 25 pounds (11.3kg).

Overview

CEB Press (aka "The Liberator"). See CEB_Press_6#Instructional_Files for detailed pictures of the latest machine build (v6), and for an exact picture of v6. Version shown is v3.
Bricks pressed on The Liberator

The Liberator is OSE's automatic, high throughput Compressed Earth Brick Press. It is named The Liberator because it is intended to free people from the single highest cost of living - housing. See Cost of Living.

The CEB is at product release status and is being actively manufactured at Factor e Farm. The presses was used heavily as a part of the Factor e Farm Infrastructure Buildout 2011. Builds using the OSE CEB ress continued with the Microhouse 1, Microhouse 2, Microhouse 3, and MicroHouse 4 built in 2014 - [1]. We have also built a utility room brick floor and an 8' wall section out of CEBs in the 2016 build of the Seed Eco-Home.

In 2020, we did a CEB Microhouse Build in Belize.

The bill of materials cost of the current, fully-automated machine is about $5000 US. See CEB Press#BOM.

The machine can also be made as a manually-controlled version with hydraulic valves. Other options are:

  • small or large hopper
  • with or without hopper shaker
  • automatic controller at 6-10 bricks per minute, depending on power unit

We are currently selling the full machine without power unit for $10k FOB Kansas City, lead time 2 months. Email info at opensourceecology dot org.

  • Price is FOB Kansas City, Missouri, USA, for a fully assembled machine, with quick couplers, ready to be plugged in to a power source. Price for other packing/crating options is extra.
