==='''WHO''' are you?===
*''Name'' - Alvaro

*''Location (city, country)'' - Isle of Wight, United Kingdom

*''Contact Information (email, phone, Skype)'' - e: alphydan (at) gmail (dot) com, t: @alphydan, s: alvaro.feito

*''Introductory Video'' -

*''Resume/CV'' -
Education:
MSc Theoretical Physics (Madrid, Spain) 
PhD in Quantum Physics (Imperial College, London) 
Degree in PedagogyExperience: 
Engineers without Borders (@Uni). 
International Design and Development Summit participant. 
2 years working in the wind industry (large scale, >2MW) 
I have lived in Spain, USA, United Kingdom, Germany and Denmark.

==='''WHY''' are you motivated to support/develop this work?===
*''Do you endorse open source culture?''
certainly. At work, at home, with friends, in the bathtub, every-time I can!

*''Why are you interested in collaborating with us?''
Mostly to change the world for the better!

*''How do you think that the GVCS can address pressing world issues?''
I think the largest contribution is to demonstrate that it is possible. Show that open source and small scale works.

*''What should happen so that you become more involved with the project?''
I would need more savings / income.

*''What are you missing in the project?''
More focus and documentation on agriculture / food / health / social interaction. A deeper self-sufficiency assessment (Energy I/O goal)

*''What are your suggestions for improvement of the project?''
Why do all machines of the construction set look black? :) Not critical, but not sexy either.

==='''WHAT'''===
*''List all of your skills in these areas: Communications - Organizational - Computer Support - Finances - Design - Natural Building - Electronics - Automation - Metallurgy - Engineering - Fabrication - Agriculture - Energy - Architecture - Video/Graphics/Art - PR/Marketing - Education - Construction - Industry - CNC - Chemistry - Product Design - Other''
 Communications --I speak Spanish, French, English and German, blog and I am a good speaker, if I may say so myself! :) (especially to explain complex concepts) 
I also use Poetry and Dance to communicate.
 Computer Support --5 years of linux experience, 2 years of web development (python, django, drupal, wordpress, html, css). 
Math: LaTeX, Octave, Python, ... 
Design --Some web and logo design experience 
Natural Building --have done a full reform of a mountain house (structural beams, lifting stone walls, treating wood, making cement floors, insulating with hemp, re-doing roof, etc). 
Engineering --PhD in theoretical physics. With some experimental involvement with lasers. Worked 2 years in the wind industry. 
Energy --Worked with life-cycle-analysis of energy systems, analysed wind potential of sites, have done repairs in wind-turbines. Good grasp of world energy situation (I maintain a Spanish blog on it www.cenit-del-petroleo.com). Currently working on a small-scale energy web-startup 
Video/Graphics --user of Inkscape, Gimp, Blender, 
Education --I very much like teaching. I have a degree in pedagogy, have worked as private teacher, tutor for baccalaureate, ... mostly teaching science. 
Chemistry --Good theoretical foundation. As a physicist I can easily learn, grasp and improve concepts. 
Product Design --Experience in building and designing Appropriate technology (solar ovens, water filters, ropeways, ram-pumps). I collaborated with MIT's http://iddsummit.org/ developing millet threshers, manual brick presses, battery chargers, etc.

*''How have you already contributed to the project?''
Small contributions. I updated the brochure, made a few graphs, and participated in OSE-Europe discussions.

==='''HOW''' can you help?''===
*''How are you interested in contributing to the work of GVCS development?''
As a first step, I would like to help develop renewable energy solutions. I can definitely help with the wind turbine.

*''Can you volunteer to work with us, and if so, how many hours per week?''
3h/week at the moment (as I have a full time job + a startup on the back-burner)

*''Are you interested in working with us for pay? If so, what services can you offer, and what is your hourly or per-project rate?''
no money yet.

*''Are you interested in [http://openfarmtech.org/wiki/Dedicated_Project_Visit Dedicated Project Visit]?''
Definitely.

*''Are you interested in purchasing equipment from us to help bootstrap development?''
Not yet.

*''Are you interested in bidding for consulting/design/prototyping work?''
yes.

*''Are you a [http://openfarmtech.org/wiki/True_Fans True Fan]? If not, why not?''
I may be jobless soon and need all my savings for a startup.

*''Would you like to see yourself working with us on a full-time basis?''
yes.

*''Are you interested in using the technologies that we are developing directly?''
yes, in a couple of years.

*''Are you interested in being part of the world's first, open source, resilient community? The GVCS is the preparatory step for the OSE Village Experiment - a 2 year, immersion experiment (2013-2014) for testing whether a real, thriving, modern-day prototype community of 200 people can be built on 200 acres using local resources and open access to information? We are looking for approximately 200 people to fill a diverse array of roles, according to the Social Contract that is being developed. This may be the boldest social experiment on earth - a pioneering community whose goal is to extend the index of possibilities regarding harmonious existence of humans, ecology, and technology - as a beacon of light to benefit of all people on Earth.
possibly.

{{Category=Solar Turbine}}
A ''solar concentrator'' is a key part of a [[Solar Turbine]], and also a key part of a [[foundry#concentrated solar foundry|solar furnace]].

Please contact joseph.dolittle at gmail.com for more information.

==Survey of Solar Concentrator Implementations==

First, see a comprehensive review of solar concentrator power by Achmed Khammas (in German) - [http://www.buch-der-synergie.de/c_neu_html/c_04_11_sonne_verstaerkungstechnik.htm#LPT]

==Example==

We are proposing a [[Linear Fresnel Solar Concentrator]] such as this designed by [http://www.hdsolar.com/ Heliodynamics Ltd.]:

[[Image:fresnel_collector.jpg]] from [http://www.redrok.com/images/hdsolar.jpg]

The differences:
*In the above design, the structure holding the collector panels is curved. Ours will lie flat on the ground; only the mirrors will be angled. This will reduce structural costs.
*The collector will be higher and wider: 6 inches wide to match the width of the mirrors.

==Design v1.0==

Just a question, is the fiberglass mandatory?
Are there alternatives?
Googling gives me cotton, cellulose, sheeps wool...
Fire retardation can be done non-toxic according to these articles (through borates).

=== Working Questions ===

*what is the ideal spacing between slats? The current design is assuming optimum functioning at the equinox. Is this appropriate?
*What is the best engine to use? We are considering building a Tesla Turbine for the purpose. Will we be able to produce enough steam for the purpose?
*The collector is a bit short on design. How will the water be fed in? What is the best way to join sections of pipe? What is the best way to mount the collector?
*What details need to be considered to modularize the collector?

Please submit drawings, designs, ideas directly to this page or forward to joseph.dolittle [at] gmail.com

Thanks for your contributions!

==Feasibility Study==

We must go through a basic feasibility study to understand the importance and potential of solar concentrator power. First, we are considering ''solar concentrators'' for solar '''electric''' power. While there are many solar electric system options available- from photovoltaics and stirling engines to Rankine cycle low temperature electrical generators and many others - we believe that solar concentrator-powered [http://openfarmtech.org/index.php?title=Boundary_Layer_Turbine boundary layer turbines] are the lowest cost, most ecological, and simplest to manufacture route - for bringing in solar energy as a '''mainstreamable source of energy for advanced cultures'''. The future of energy ''is'' solar.

NOTE: Note also that solar cells do hold good promise in the future. This would be feasible, in a decentralized economic system, if solar cells are able to be produced in small scale facilities. One such technology is ribbon PV technology, extruded using an appliance-sized machine that takes only 1 kW of power (see [http://www.evergreensolar.com/app/en/technology/ Evergreen Solar] for an example). Moreover, this can be accomplished in a decentralized economic system only if the raw feedstock - solar grade silicon - can be produced in distributed locations - such as, even, [http://openfarmtech/weblog/ Factor e Farm]. Silicon is made from sand, and sand is ubiquitous. If abundant energy is available (such as solar concentrator power), then it is just a matter of procedure to produce all the solar grade silicon that is needed - and transcend the present "shortage" of pure silicon. The latter is merely an artifact of the economy of scarcity, where non-value-neutral technologies promoted by special interests dominate the landscape.

==Solar Power Basics==
Consider these basic facts relevant to solar power:

*Solar insolation on a clear day is about 1 kW/square meter
**Considering cloud cover and day/night cycles, a place like Missouri gets 6 kWhr/square meter/day of insolation throughout the year, on average. [http://rredc.nrel.gov/solar/old_data/nsrdb/redbook/sum2/03947.txt]. You can check the insolation for your location in the uSA as well. Other sources indicate it is less, only 4.73. (http://solardirect.com/pv/systems/gts/gts-sizing-sun-hours.html) *detailed weather data is available for free here http://www.ncdc.noaa.gov/oa/ncdc.html free if you are coming from a .edu address otherwise about $20.* Good for simulations. Also there is a program distributed by Sandia labs called the Solar advisor Model. It is quite good and can be used in combination with other simulation methods to do earlier phases of the simulations (e.g. determine the sunlight present at the absorber for various types) as you can extract the data from various stages of the simulation from it in table form easily.
*The earth intercepts 10,000 more times energy from the sun than we currently use in all fossil and nonfossil fuels today.
*The energy intercepted per acre of land is 4 megawatts.
*If overall energy conversion efficiency for that land area were 5%, then you would produce 200kW of power from that acre of insolation.
**The boundary layer turbine is proven to be at least 25% efficient for unoptimized experiments in the literature. [http://openfarmtech.org/index.php?title=Boundary_Layer_Turbine] Note that this page is missing and I cannot find the reference on the wiki, but that may well be the mechanical efficiency of the turbine, not of a steam engine utilizing it. That is very low. A normal bladed turbine is more than 60% efficient mechanically. More importantly and fundamentally the centrifugal force on a steam turbine of small size is the main limiting factor here. There is a more detailed analysis of this in the forum http://openfarmtech.org/forum/discussion/149/steam-engine .
**Counting overall system efficiency, 10% efficiency is easily attained. In fact it is even higher for dish stirling engines. Infinia gets 28% with the thermal-electric conversion at full sun, and the dish collectors are more than 90% efficient, the absorber is about 80%, so that leaves 20%. Low cost rankine engines using automobile supercharger turbines used for hospital electric power can get 8% or so at full sun. Note it goes down substantially at lower insolation, unlike solar panels, and this must be factored in to estimate overall system performance accurately.
**If only half the land area is solar collectors (rest is access, etc.), then 5% is a reasonable figure. There's no reason we can't do substantially more than half.
*The 200 kW obtainable per acre is comparable, on a per-acre basis, to coal power plants.
**Coal power plant of 1 square mile - 640 acres/mile * 200kW/acre ~ 100 MW output per square mile if the area was in solar concentrators. So, 10 square miles would constitue a gigawatt solar power plant. This is comparable to the area and output of coal plants.
**A solar thermal electric plant of 177 MW on one square mile was recently installed in California - [http://ausra.com/news/releases/071105.html]
**Nuclear power plants are typically 1 square mile in size [http://www.nucleartourist.net/areas/areas.htm]
*The 200 kW/acre is also twice the per-acre power of the most advanced Stirling engine thermal electric generators. [http://peswiki.com/index.php/Directory:Stirling_Energy_Systems]
**This might not be because the advanced Stirlings are not efficient, but because there is so few of them per acre. This would be no different for a steam system though. A concentrator is a concentrator.

==Cost==

And basic cost figures are:

*For comparison:
**coal and nukes are about $1500/kW of installed power
***Fuel costs for coal are about 1.5 cents/kWhr
***Total energy production costs are 4-10 cents/kWhr [http://www.maintenanceworld.com/Articles/turbosteam/thecost.html]
**Solar Cells are about $6000/kW of installed power
*OSE Concentrator (all figures are general estimates):
**Estimated $180 per "panel" of 4x8 feet
***Frame costs $47
***SLATS cost $87
***Dial cost (16 set-screws is the major cost) $2
***Receiver cost: $36
***Receiver frame: $8
**An estimated 10 panels are needed to run a tesla turbine or equivalent. Total cost of panels would be $1800.
**Turbine and generator are estimated to cost $600.
***Assuming a low 5% efficiency, 300 ft2 of collectors will produce 1.5 kW of electric power.

Original estimates with more details and links
*Cost of mirrors for such a collector is about $1/sq ft
**The heart of a solar collector is mirrors
*Balance of system costs for the collector incude structure and collector tube assembly
**Balance of system costs should be about $5/sq ft
*Costs for solar cells that are presently available are $40/sq ft, or a factor 8 more
*The boundary layer turbine [http://openfarmtech.org/index.php?title=Boundary_Layer_Turbine] material cost is negligible compared to the collector cost - $300 for the model that we are developing
**5 kW turbine, with off-shelf generator head [http://openfarmtech.org/index.php?title=Boundary_Layer_Turbine#Bill_of_Materials:_Boundary_Layer_Turbine] - is $600 total, plus $400 in labor = $1000 neocommercialization [http://www.p2pfoundation.net/Neocommercialization] cost
*Collector costs for the 5 kW turbine generator are:
**500 square feet => 50 sq meters => 50,000 W @10% efficiency => sufficient for 5 kW electric generation
**But, turbine scales at $20 per additional kilowatt of power output, and $40 for additional electric power output.
**Cost of 500 square feet is $2500.
*'''Nominal 5 kW system costs $3500, which is <80 cents/watt of installed power'''
*Nominal 100 kW system costs $50,000 for solar concentrators, and $2500 for generator heads, and about $2500 for the turbines.
**'''Total of $55k for 100 kW or about 55 cents per watt of installed power
'''
Bottom line: For anyone who understands these numbers, this "we can be sure it will change life as we know it", quoted regarding energy from [http://www.internationalistmagazine.com/2007-earlyfall/2007-earlyfall_commentary.html another article] discussing P2P energy solutions. This is cheaper than any known power generation strategy.

'''Note the assumptions:'''
#'''Open source design fuels advanced, small-scale, optimized digital and flexible fabrication'''
#'''As such, labor costs are minimized'''
#'''Fabrication infrastructure may be capitalized via voluntary contributions from stakeholders, such as we're exploring- as a novel way to fund productive infrastructures'''

Note that laser cutting may be required for turbine fabrication, but this tool should also be opensourced and made available at a predicted cost of $5k for a laser cutter for 1/16 inch stainless steel plate.

==Reality Check==

One must study the above data carefully to become convinced of the possibility. The greatest question that may arise is not whether the efficiency of the turbine is correct. The figure of 10% that we are using has been proven, and it is conservative. The real question is, can the cost deliverables be met.

Using the simplest possible structural design for the concentrators, described in our [http://openfarmtech.org/OSE_Proposal.doc proposal in Fig. 5a], such as:

[[Image:hd16.jpg]]

the $5/sq ft balance of system cost should be achievable. If it is not achievable by utilizing off-shelf steel or lumber components, then we will utilize [[CEB Press|compressed earth blocks]] and [[Swingblade Sawmill|self-milled lumber]] to reach the cost requirement.

==Weak Link in the System==

The weak link in the system is the boundary layer turbine itself. So far, we have heard conflicting messages on its feasibility. Scientific journals have showed 25% efficiency for a small, steam-powered boundary layer turbine. If that is true - then this is enough information to go on to take on the development of the turbine. Indeed, I found that Dan Granett ran a 16-disk, 12-inch diameter turbine successfully on compressed air to generate 4 kW of electric power. His design did not have seals, so he designed a simplified turbine, with seals - [[Boundary Layer Turbine]] - which is the design that we're working on.

We are interested in tracking down those researchers. One of them is Warren Rice, author of the above 25% turbine paper. He was professor of Engineering Science at Arizona State University, Tempe, AZ, when he wrote the paper in 1963. We would appreciate any help in tracking down the true story of why the boundary layer turbine has not attained wider acceptance. Note: it needs to be verified if this 25% figure refers to mechanical efficiency or not. If so that is the explanation; bladed turbines have more than 60% efficiency at optimal speed.

If there is a small-scale turbine that is so efficient, why has this not been commercialized? Our research indicates that this is because much more efficient bladed turbines have been produced. However, those turbines are at least a factor of 10 times more expensive. '''''Thus, for particular applications, the boundary layer turbine may be a suitable, cost-effective option.''''' This is also the conclusion drawn on p. 35 of Rice, Warren, Transactions of the ASME, Journal of Engineering and Power, January 1965.

If the turbine does not work as expected, we will move on to other options. One retrogressive option could be as primitive as proven steam engines, which are 5% efficient for unoptimized models. We are talking of ridiculously low performance, but if the final system cost is correspondingly low, then we just might have a technology that could change the world. Indeed, 5% efficiency is a factor 3 lower than solar cells - and given the significantly lower cost per installed watt than photovoltaics, that may be a much better solution than photovoltaics.

==Night Time Operation==

Night time operation is feasible by using heat storage. This is done by Ausra on the commercial level already. [http://ausra.com/technology/]

Tamera has hot oil system in place - http://www.solarpowervillage.info/

http://peswiki.com/index.php/Congress:Top_100_Technologies_--_RD#Top_100 says:

==Competition==

Stirling Energy Systems utility solar - 20-year purchase agreement between Southern California Edison and Stirling Energy Systems, Inc. will result in 20,000+ dish array covering 4,500 acres capable of generating 500 MW, at a cost competitive to grid power. 37 foot diameter dishes. Each dish yields 25 kW. Nice. pi*18^2= 1074 sq feet, or exactly 100 square meters. 25% overall efficiency for the most advanced Stirling engine.

''Note:'' The above example yields 100 kW/acre. Our calculations indicate the following for our system. 4 MW/acre is the basic insolation rate. If it is converted to electricity with an overall efficiency of 5%, this results in 200 kW/acre. If we have a 50% fill factor, we have 100 kW/acre. Our simple system is predicted to be competitive with advanced Stirling engines on a per-acre power basis. Our cost will be approximately 10 times lower.

==Ecological Review==

Flat concentrators are the simplest to manufacture. They can also be scaled infinitely. Parabolic ones are scaleable, too, but expensive. Dish systems are even more expensive, and not scaleable.

Photovoltaic systems have been out of reach for society since they were invented. In our opinion, they will not become affordable to consumers until a true renegade innovator, not mainstream companies, make them available. Today, with no technological breakthroughs, solar concentrators may be implemented. If developed in the open source context, we predict 80 cents/installed watt as above. Welcome energy abundance, bye-bye to many of the present geopolitical quabbles.

==Possible Design Alternatives==

'''Compound Parabolic Trough Solar Concentrator'''.
This design uses non-imaging optics and therefore does not require daily tracking, only some seasonal tracking. More details at Fossil Freedom [http://www.fossilfreedom.com/increase-output.html]. A variation on this concept would be a bi-paraboloid Fresnel-like arrangement of flat mirrors, similar to the example above.

=Dish Systems=

Dish systems are inherently capable of higher concentration ratios because they focus in two dimensions rather than one for linear concentrators. Therefore if more intense sunlight is required they may be preferred. Examples where higher concentration ratios would be needed are

* Higher efficiency turbines by providing a higher temperature ratio, thus a higher theoretical Carnot efficiency
* Multi-junction concentrator photovoltaic cells, which are approaching 40% conversion efficiency, and operate best at 400-1000 suns illumination. They use a large amount of cheap mirror area and a small amount of PV cell, so even though the cells themselves are difficult to produce independently, they are only a small component of the overall system.
* Metal casting/processing which may require high temperatures
* Calcination of minerals to produce cement, which also requires high temperatures.

Parabolic shapes can be generated by the method of spincasting. Rotating fluids assume a parabola under gravity as explained at [http://en.wikipedia.org/wiki/Liquid_mirror_telescope#Explanation_of_the_equilibrium Liquid Mirror Equilibrium]. Thus by spinning a casting bed or mold and adding a molten or castable material (paper fibers with setting agent, reinforced concrete, etc) it will automatically produce a paraboloid. Segments for an expandable or large dish can be made by offsetting the mold from the center of rotation on a pivot arm, with a counterweight for balance. Once created, the surface is then polished if needed, and covered with a reflective material such as small mirrors, aluminum foil, etc.

===Low Tech Strip Concentrator===

This would be suitable for occasional or batch uses. For more regular use a more robust design would be preferred.

* Strips of a flexible, smooth surfaced support material are formed into parabolas with support ribs as needed. For example 5 mm Lauan plywood with exterior paint fastened to curved ribs. The strips should be approx as wide as your rolls of aluminum foil, and a convenient length such as 8 ft for plywood.
* Use contact cement to glue foil to strips.
* Mount strips in parallel on a support frame, and tilted to a common focus.
* Support frame in turn is hung from polar aligned pipe, so single axis motion will follow the sun.
* Target for sunlight is supported by a frame with a sliding adjustment parallel to polar aligned pipe. This allows for seasonal adjustment of sun elevation. The frame should be metal with foil wrap to deflect intense sunlight.
* Target mount should allow for using various targets for different uses.
* Alternately the upper end of the polar aligned pipe can be raised or lowered for seasonal changes, but this may be too heavy to adjust for a large system. Another alternate is to angle one end of each strip vertically for seasons.
* Counterweights are added below the dish to balance the heated target.
* The entire system is tarped over to protect it from rain, and accidental burns when not in use. Covering some strips or parts thereof can adjust power level as needed.
* The focal line would be approx one strip wide by whatever surface accuracy the foil has in the length direction. Uses are any that need batch high heat.
* Extra low tech: rests frame on ground propped up by support legs to sun angle, and moved manually. This will only be practical for small versions.

Wind Turbine

{{Category=Wind energy}}

{{ToolTemplate|ToolName=Wind Turbine}}

Open Source Ecology is involved in researching, developing and building open-source technologies for clean, local electricity-generation. As well as [[:Category:Solar Power|solar power]], we like wind power. Wind power or solar or both may be appropriate, depending on local materials and local weather conditions.

Specifically, we are interested in open-source designs for a wind turbine that can provide electricity for a small community. Small wind turbines like this are usually 7 feet (2m) to 25 feet (7.6m) in diameter.

==Design specifications==
{{Wanted|We need to define exactly what we need from our wind turbine. Edit this list.}}
*'''Scalability''' - scalable from ??? to ???
*'''Low-cost''' - must cost less than $1 per installed watt and $0.05/kWh produced on a medium speed site (6m/s average speed [13.4mph, 21.6km/h])
*'''CAD files''' to allow parts to be digitally fabricated. We could just take an existing open-source design, and get one of our draftsmen to make the CAD file. Good CAD files could allow for scalable digital fabrication: the blades could be printed in a range of sizes, depending on what you need

==Existing open-source wind turbines==
Several wind turbines have already been open-sourced and it should be possible to use them for the [[Global Village Construction Set]]:

*[http://www.applied-sciences.net/library/zoetrope.php '''Zoetrope'''] is a vertical-axis wind turbine made from common materials such as stove pipe, metal brackets, plastic sheet and a trailer hub. Generates about 150-200W in winds of 20mph (32km/h). [http://www.applied-sciences.net/library/data/zoetrope-wind-turbine.pdf Construction Guide]. The major parts are: [http://69.175.14.181/catalog/product_info.php?cPath=22_30&products_id=175&osCsid=11bdc6671edf38fcc578ca1da051f8d8 parts kit for $159] (unless you could order one from a Fab Lab/ a hackerspace with a water-jet cutter), [http://www.amazon.com/2x1x1-Turbine-Generator-Neodymium-Magnets/dp/B0012DIXE4 24 neodymium magnets for $140], [http://www.etrailer.com/Trailer-Hubs-and-Drums/Dexter/34822BX.html?feed=npn trailer hub for $26]. There are also a bunch of pieces like nuts and bolts, but those are the main one, and come to $425 excluding shipping.
*[http://www.otherpower.com/otherpower_wind.shtml OtherPower.com] have several complete plans for wind turbines that can be built at home. Their site has -
**[http://www.otherpower.com/turbineplans.shtml Complete plans for a 10 foot (3m) turbine] that puts out 100W in 10mph (16km/h) winds and 700W in 25mph (40km/h) winds.
**[http://www.otherpower.com/bigmills1.html Design of a 14 foot (4.25m) turbine] that does 200W in 10mph (16km/h) winds and 1500W in 25mph (40km/h) winds. This is the record of a project rather than a replicable open-source design.
*[http://www.velacreations.com/chispito.html '''Chispito''' Wind Generator]. Chispito is made from recycled/salvaged materials, completely open-source with clear instructions and designed for simplicity. Open-source instructions for building both the turbine and the tower are available. Each turbine generates about 100W; most people seem to use a bunch of them. This is probably smaller that what we are looking for.
*http://www.scoraigwind.com/ has a lot of information on wind turbines, but no fully open-source plan
*[http://www.scoraigwind.com/pmgbooklet/itpmg.pdf Open source alternator] for wind turbines
*[http://www.onawi.org Onawi] is a not-for-profit organization dedicated to developing open-source wind turbines. No signs of progress yet, but watch this space.

==What kind of turbine?==
The first design decision we have to make is which kind of wind generator best suits our needs

===Vertical Axis Wind Turbine|Vertical-axis wind turbines===
[[File:Pac_wind.jpg|200px|thumb|right|Pacwind VAWT Vertical Axis Wind Turbine Seahawk]]
Verical Axis Wind Turbines or VAWTs offer a number of advantages over traditional horizontal-axis wind turbines (HAWTs). They can be packed closer together in wind farms, allowing more in a given space. This is not because they are smaller, but rather due to the slowing effect on the air that HAWTs have, forcing designers to separate them by ten times their width. VAWTs are rugged, quiet, omni-directional, and they do not create as much stress on the support structure. They do not require as much wind to generate power, thus allowing them to be closer to the ground. By being closer to the ground they are easily maintained and can be installed on chimneys and similar tall structures.

In addition, by being closer to the ground, VAWTs have the ability to take advantage of the tunnelling effects of small buildings and structures (provided the structures are build close enough) small VAWTs are also used in corners of buildings (usually the corner of a balcony).

Although VAWTs are not as efficient as HAWTs they are considered more reliable and much easier to maintain. One disadvantage of the VAWT is that the blade that moves ''into the wind'' also moves ''against'' the wind, slowing down the turbine. This could be addressed by a shield that adjusts to the direction of the wind and covers the blade that moves into the wind. This could be done with some kind of vane. However, this would complicate the design significantly, incl. bearings for the shield. So this may not be worth it ... probably easier to just build more VAWTs or build them bigger. But who knows ? Come up with a good sail/shield design and this might be just the breakthrough that VAWTs have been waiting for.

A good step by step guide can be found on [http://www.instructables.com/id/VAWT-Lenz-type-Stage-1-Converting-wind-power-to-/ this link]: a small Savonius wind turbine that takes advantage of the [http://en.wikipedia.org/wiki/Venturi_effect Venturi effect].

There is a small scale printable VAWT on thingiverse http://www.thingiverse.com/thing:6899

===Horizontal-axis wind turbines===

===Airborne wind turbines===
A turbine attached to a lighter-than-air ballooon, such as being developed by [http://www.magenn.com/ Magenn]. I think we can reject this as too complex and too experimental for our purposes.

#[http://www.google.com/patents/about?id=2is6AAAAEBAJ Wind driven apparatus for power generation] - expired patent for a tethered airborne turbine. This design generates power at the turbine and transmits it to the ground.
#[http://peswiki.com/index.php/Directory:High_Altitude_Wind_Power High Altitude Wind Power at PESwiki]

===Kite generators===
A high-flying power kite tethered to a generator on the ground. The kite tugs on the tether, which spins a turbine and generates electricity. All the machinery can be kept at ground level; only the sail is airborne. This allows for easy maintenance.

The two main advantages of this design are that reaches the more powerful winds higher up, and it may come in cheaper than a turbine. [http://cfpub.epa.gov/ncer_abstracts/index.cfm/fuseaction/display.abstractDetail/abstract/8602/report/F This] report from the WPI Kite Power Team says there is an "anticipated 50% cost savings over wind turbines".

We can probably buy an off-the-shelf power kite. [http://www.aliexpress.com/product-fm/397570670-Kite-Power-Kite-Sport-Kite-5sqm-Sail-Area-Power-Tricktion-Kite-Quad-line-Control-wholesalers.html Here] is a 5m2 one for $166. [http://www.virtualvillage.com/Items/003300-010 Here] is a 2.7m2 one for $14. [http://www.powerkiteshop.com/ozone_method.htm This] seems to be a top-of-the-range one - it's $600 for 6.5m2. Alternatively, we could try to build our own kite.

This would need to be attached to the open-source [[electric motor]] we're designing, and a microcontroller. All the hardware is on the ground, which makes maintenance and set-up easier. The control will be the main design challenge.

Kites can extract power more economically than wind turbines because they fly at higher heights than turbines can operate."''
#http://www.kitegen.com/en/?page_id=7

==Siting of Turbines ==
A critical step to make wind profitable or optimal is putting the turbine in the right spot or site (turbine siting). This involves two main factors: the speed of the wind and the turbulence in the wind. Since the energy available in the wind varies with (E ~ v^3) a site with slightly less speed can produce a lot less energy. Siting requires measuring the speed of the wind for at least a year with a measurement mast (or small weather station) in a spot close to the site of the turbine. There exist open-source software to then propagate the measurements (using more or less complex computational fluid dynamics) to find the speeds on the topography. One example: http://awsopenwind.org/

= Share your Vision =

Share your Vision with us! We are all coming from different backgrounds with different ideas and different feelings what should be done next in Europe. As there are many people interested in the project give us your Vision what OSE in Europe should be about.

Create a subpage like [http://opensourceecology.org/wiki/Open_Source_Ecology_Europe/Firstname_Lastname this] or put it on another place in the web you like and add the link to the column above.

Don't read Vision Papers of other people before you write your own, so you will be unbiased. You also can put your Vision below your Team Culturing you personal wiki page, as the Vision is somehow an extension of the Team Culturing with more bias on the emotional and motivational stuff.

Put in the vision paper what you expect of OSE Europe. What you want to happen, how you see it in three years, and how you contributed to this process. Put in everything what you can think of, but don't get (too) unrealistic. This will help us all to get a common foundation and what to do next.

Your Vision can of course be in every format you like. Audio, Video or Written or what you can think of. Feel free to do choose your media. More about the idead behind sharing your vision you can find [http://opensourceecology.org/wiki/Open_Source_Ecology_Europe/Vision here]

==Goals==

OSE Europe will be an [[OSE Regional Charter|OSE Regional Group]]. The main goals will be defined soon.

What will be the goals of OSE Europe? There are several possibilities, not mutually exclusive:

* OSE Advocacy and "Publicity" in Europe
* An open business, where people can work for a living building and selling products using OSE technology
* A FactoreFarm for Europe: Means developing tools in parallel with the current Factor e Farm.
* A community: creating a self sustaining village using the GVCS

Wind turbine Intro

2011-06-23T15:09:31Z

Alphydan: /* Design specifications */

{{Category=Wind energy}}

{{ToolTemplate|ToolName=Wind turbine}}

Open Source Ecology is involved in researching, developing and building open-source technologies for clean, local electricity-generation. As well as [[:Category:Solar Power|solar power]], we like wind power. Wind power or solar or both may be appropriate, depending on local materials and local weather conditions.

Specifically, we are interested in open-source designs for a wind turbine that can provide electricity for a small community. Small wind turbines like this are usually 7 feet (2m) to 25 feet (7.6m) in diameter.

==Design specifications==
{{Wanted|We need to define exactly what we need from our wind turbine. Edit this list.}}
*'''Scalability''' - scalable from ??? to ???
*'''Low-cost''' - must cost less than $1 per installed watt and $0.05/kWh produced on a medium speed site (6m/s average speed [13.4mph, 21.6km/h])
*'''CAD files''' to allow parts to be digitally fabricated. We could just take an existing open-source design, and get one of our draftsmen to make the CAD file. Good CAD files could allow for scalable digital fabrication: the blades could be printed in a range of sizes, depending on what you need

==Existing open-source wind turbines==
Several wind turbines have already been open-sourced and it should be possible to use them for the [[Global Village Construction Set]]:

*[http://www.applied-sciences.net/library/zoetrope.php '''Zoetrope'''] is a vertical-axis wind turbine made from common materials such as stove pipe, metal brackets, plastic sheet and a trailer hub.

==What kind of turbine?==
The first design decision we have to make is which kind of wind generator best suits our needs

===Vertical Axis Wind Turbine|Vertical-axis wind turbines===
[[File:Pac_wind.jpg|200px|thumb|right|Pacwind VAWT Vertical Axis Wind Turbine Seahawk]]
Verical Axis Wind Turbines or VAWTs offer a number of advantages over traditional horizontal-axis wind turbines (HAWTs). They can be packed closer together in wind farms, allowing more in a given space. This is not because they are smaller, but rather due to the slowing effect on the air that HAWTs have, forcing designers to separate them by ten times their width. VAWTs are rugged, quiet, omni-directional, and they do not create as much stress on the support structure. They do not require as much wind to generate power, thus allowing them to be closer to the ground. By being closer to the ground they are easily maintained and can be installed on chimneys and similar tall structures.

In addition, by being closer to the ground, VAWTs have the ability to take advantage of the tunnelling effects of small buildings and structures (provided the structures are build close enough) small VAWTs are also used in corners of buildings (usually the corner of a balcony).

Although VAWTs are not as efficient as HAWTs they are considered more reliable and much easier to maintain. One disadvantage of the VAWT is that the blade that moves ''into the wind'' also moves ''against'' the wind, slowing down the turbine. This could be addressed by a shield that adjusts to the direction of the wind and covers the blade that moves into the wind. This could be done with some kind of vane. However, this would complicate the design significantly, incl. bearings for the shield. So this may not be worth it ... probably easier to just build more VAWTs or build them bigger. But who knows ? Come up with a good sail/shield design and this might be just the breakthrough that VAWTs have been waiting for.

A good step by step guide can be found on [http://www.instructables.com/id/VAWT-Lenz-type-Stage-1-Converting-wind-power-to-/ this link]: a small Savonius wind turbine that takes advantage of the [http://en.wikipedia.org/wiki/Venturi_effect Venturi effect].

There is a small scale printable VAWT on thingiverse http://www.thingiverse.com/thing:6899

===Horizontal-axis wind turbines===

===Airborne wind turbines===
A turbine attached to a lighter-than-air ballooon, such as being developed by [http://www.magenn.com/ Magenn]. I think we can reject this as too complex and too experimental for our purposes.

#[http://www.google.com/patents/about?id=2is6AAAAEBAJ Wind driven apparatus for power generation] - expired patent for a tethered airborne turbine. This design generates power at the turbine and transmits it to the ground.

===Kite generators===
A high-flying power kite tethered to a generator on the ground. The kite tugs on the tether, which spins a turbine and generates electricity. All the machinery can be kept at ground level; only the sail is airborne. This allows for easy maintenance.

The two main advantages of this design are that reaches the more powerful winds higher up, and it may come in cheaper than a turbine. [http://cfpub.epa.gov/ncer_abstracts/index.cfm/fuseaction/display.abstractDetail/abstract/8602/report/F This] report from the WPI Kite Power Team says there is an "anticipated 50% cost savings over wind turbines".

We can probably buy an off-the-shelf power kite. [http://www.aliexpress.com/product-fm/397570670-Kite-Power-Kite-Sport-Kite-5sqm-Sail-Area-Power-Tricktion-Kite-Quad-line-Control-wholesalers.html Here] is a 5m2 one for $166. [http://www.virtualvillage.com/Items/003300-010 Here] is a 2.7m2 one for $14. [http://www.powerkiteshop.com/ozone_method.htm This] seems to be a top-of-the-range one - it's $600 for 6.5m2. Alternatively, we could try to build our own kite.

This would need to be attached to the open-source [[electric motor]] we're designing, and a microcontroller. All the hardware is on the ground, which makes maintenance and set-up easier. The control will be the main design challenge.

''Low-cost - must cost less than $1 for every watt it delivers when the wind speed is 3.3m/s (7.4 mph or 12 km/h)''

This sentence doesn't make much sense.

Do we mean: less than $1 per watt installed? (If by "watt delivered" we mean "watt produced", then we should talk about energy (watt hour) not about power (watt)).

If we are talking about $1/W installed, then the wind speed is irrelevant.
The standard measure for wind turbines will be average $/Wh (currency unit per unit of energy produced), for a given average wind speed. (this too is a rough estimate as the shape of the wind speed distribution can greatly alter the money/energy unit the turbine costs).

So my recommendation:

''Low-cost - must cost less than $1 per installed watt and $0.05/kWh produced on a medium speed site (6m/s average speed)''
