<p>VDP: </p> <hr /> <div>{{Category=Home fittings}}<br /> {{Category=Food Storage and Processing}}<br /> <br /> ==Thermal mass fridge==<br /> [[File:Thermal mass refrigerator.png|right|thumb|150px|Thermal mass refrigerator]]<br /> Described in Volume III of the [[Earthships|Earthship]] manual. Basically uses the coolness of the earth in summer to keep cool.<br /> <br /> ==Persian windcatchers==<br /> A [http://en.wikipedia.org/wiki/Windcatcher windcatcher] is a tower rising up to catch high winds and funnel them down into an area to be cooled. Simultaneously, it acts as a chimney letting hot air rise out. <br /> <br /> ==Eutectic Fridge==<br /> Designing a refrigeration on the Eutectic cell or Eutectic fridge principal can increase efficiency by a great deal. By using the phase change point of a medium you get to utilize temperature regulation at an optimum desired point, and only using the compressor after phase change has occurred. The thermal mass has an advantage here of being able to absorb heat without changing in temperature during phase transition. it means a compressor or regulator can be utilized less.<br /> http://www.autofridge.com.au/page/technical_information.html<br /> http://www.ozefridge.com.au/?page_id=22<br /> <br /> ==Heat Pump==<br /> A heat pump can produce cooling in one region, and heat on another. A complete home hot water/heating and refrigeration/air cooling system could use a heat pump to eliminate both needs with one system.<br /> http://en.wikipedia.org/wiki/Heat_pump<br /> A heat pump is also a rare and useful case in thermodynamic engineering where total energetic output can exceed input the user paid for - the electricity used for the compressor. The additional energetic input is acquired from the environment. A common fridge can produce 3-5 times more energy than electrically input as an example.<br /> <br /> In a heat pump total output = (energy for compression + energy provided by environment) * efficiency<br /> <br /> eg. 2.5 units = (2 units + 3 units) * 50%<br /> <br /> COP (Coefficient of Performance) Formula = total output / input you paid for (energy for compression)<br /> <br /> eg. COP 1.25 = 2.5 / 2<br /> <br /> Therefore it is possible in a heat pump for total output to exceed the input the user paid for, like flying a kite. You only hold the string, the wind does the rest - both are required though for the system to work.<br /> <br /> ==Einstein fridge==<br /> [[File:EinsteinFridge.JPG|right|thumb|150px|Patent drawing of Einstein's fridge. Fluids move around a series of pipes and chambers. Click to enlarge.]]<br /> Albert Einstein invented a refrigerator with no moving parts. It is powered by applying heat to one of the chambers; no electricity is required. The [[File:Einstein_Fridge.pdf|expired patent]] gives basic plans of how it works. This should be developed into a full open-source design with building instructions, bill of materials etc. It fulfils all the criteria for an Open Ecology product: it is in the public domain, it should last a lifetime and be cheap to build, it would be extremely useful to an off-grid community, it could help alleviate poverty .<br /> <br /> ==Evaporative Cooling==<br /> Very low energy consumption is required to use evaporative cooling. In the case of evaporative cooling, efficiency is reduced with increased humidity in the environment. <br /> http://en.wikipedia.org/wiki/Coolgardie_safe<br /> <br /> ==Concept for combined thermal mass/ windcatcher system==<br /> [[File:Concept for fridge.JPG|thumb|300px|center|The top of the tower is high above the ground, where air is cooler and wind is faster. At the top of the tower are openings facing all four directions so that it always catches the wind. This wind goes down into the underground pit and cools it. During hot weather, the pit is cooled by the thermal storage of the earth. Hot air rises out of the tower. The roof of the larder is domed so that the hot air has nowhere to go except out of the tower. Food stored in the pit would need little to no energy to keep it refrigerated.]]<br /> <br /> ==Fridge efficiency methods==<br /> fullness: If a fridge has more space it thus has more air to cool to keep food below room temperature, So keeping space occupied in a fridge leads to energy savings.<br /> Shape: Simply put it should be a box with a lid that holds the cold air in when it opened like a deep-freeze.<br /> [http://www.thesimpledollar.com/2009/08/10/freezer-and-fridge-hacks-seven-ways-to-maximize-the-value-of-your-refrigerator-and-freezer/]<br /> <br /> As the [[Earthships]] manual points out, it is wasteful to put a fridge in a heated room (as most homes do). If you want to keep the fridge cool, allow it access to cool outside air.<br /> <br /> ==Converting a freezer to a high-efficiency fridge==<br /> See the links below for a very simple open-source method to convert a chest freezer into a fridge. The fridge will run on 150 Watt-hours per day (equivalent to running a laptop for 2 hours); 1000 Watt hours a day is normal. The fridge has the door on the top, which means cold air tends to sit inside it. <br /> <br /> The converted fridge yields a lifetime of service, so we can modify/fabricate with a basic CNC mill.<br /> <br /> *[http://mtbest.net/chest_fridge.html Article and instructions on the conversion]. You need something like this [http://www.amazon.com/gp/product/B0002EAL58?ie=UTF8&amp;tag=selfsufficientlife-20&amp;linkCode=as2&amp;camp=1789&amp;creative=390957&amp;creativeASIN=B0002EAL58 Freezer Temperature Controller] ($53 on Amazon) to cut the power off when the freezer cools itself to fridge temperature (about 4&lt;sup&gt;o&lt;/sup&gt;C or 39&lt;sup&gt;o&lt;/sup&gt;F)<br /> *http://blog.holyscraphotsprings.com/2010/09/chest-freezer-to-fridge-conversion-1900.html<br /> *http://www.aselfsufficientlife.com/chest-freezer-to-fridge-conversion-the-most-energy-efficient-fridge-ever.html<br /> <br /> ==Sundanzer==<br /> According to Abe at Velacreations, his Sundanzer uses 50 Watt hours per day, but it is a small refrigerator. It was $800 direct from the factory (it had a cosmetic blemish). The lifetime is 20 years+, pretty much like any fridge or freezer. It is a chest fridge, extra insulation, very efficient. You can get them in freezer models as well.<br /> <br /> ==STEVEN Ammonia Freezer==<br /> <br /> The basic principles of operation and simple construction of this ammonia absorption solar powered freezer should be easy to adapt to OSE's purposes. Combined with a high thermal mass insulated storage area, this could provide both refrigeration AND freezer storage year round.<br /> <br /> [[Media:AmmoniaAbsorptionIcemaker.pdf‎]]<br /> <br /> [http://www.lightlink.com/francis/prospectus.htm#Icemaker STEVEN icemaker url]<br /> <br /> ==See Also==<br /> *[[Proposed GVCS]]</div>

The file description was previously at appropedia (http://www.appropedia.org/Growing_under_cover )<br /> <br /> * For the 3D printer, I think you best swap the RepRap design with the ORDBot design (http://www.appropedia.org/Open_source_3-D_printers#List_of_open_design_3-D_printers ) It's stronger and I think with some thinkering you could print more materials (perhaps including metal)<br /> <br /> * Besides the seeder, perhaps include a wheeled auger (similar to http://users.skynet.be/sb021277/Pages/Nederlands/Pflanzfuchs/PF.html ) or even better, just make a 2-wheel tractor that can be fitted with an auger. The auger is a cheap tool to allow 2 people to seed quickly, and also allows other uses (ie making holes for construction, ...) The 2-wheel tractor can be based on the BCS 722. Also, it's best to have the 2-wheel tractor electrified, so it can be powered by a stationairy engine running on a biofuel (straight vegetable oil). A tractor with IC engine is possible, yet requires modification so it can run on a biofuel so it's easier to do it this way. <br /> <br /> * swap the spader with a regular rototiller but just make that rototiller easier to fabricate/cheaper. You could also make a version adapted for use on the traction engine design I made (a light vehicle such as this requires less fuel to operate the implement). A spader isn't any better (actually worse in my view as the soil isn't cut up as much. No-till is all the rage these days (see http://www.betuco.be/CA/No-tillage%20Farming%20for%20Sustainable%20Development.pdf ), but really it isn't absolutely necessairy, rather we just need equipment that is much more precise, for example rototilling only upto the depth required for planting (and not more). So make the depth settable. Even better would be to only cut up the soil exactly where you plant, so leaving the interrow-sections unaffected, however that's difficult to accomplish.<br /> <br /> * you also seem to not have many specialized agricultural tools, for example for harvesting fruit from orchards. For harvesting olives/nuts from trees, shakers/vibrators are for example used that clamp on the tree and shake off the olives/nuts. For collecting the fallen off produce, tarps on rolls are sometimes used (tarps being rolled up automatically, sliding the produce off into a bin). An other approach is by using disc brushes (round rotating brushes as used in municipal services to clean up litter from streets)<br /> <br /> ==See Also==<br /> *[[GVCS]]<br /> *[[OSE Spec]]<br /> <br /> [[Category: GVCS]]</div>

<p>VDP: </p> <hr /> <div>Schematic of a food dehydrator designed by VDP, based mainly on [http://www.motherearthnews.com/real-food/preserving-food-homemade-dehydrator-zmaz75jazgoe.aspx?PageId=1 Peter Murphy's food dehydrator].<br /> <br /> Peter's dehydrator was modified significantly by changing the dimensions (currently 45 cm long X 70 cm high X 35 cm wide -instead 29,5&quot; X 38&quot; X 15&quot; in Peter's design) of eliminating the metal heat spreaders, the chimney (replacing it with a simple air outlet hole in the middle of the top wooden panel (marked with L) and by adding a solar thermal collector (similar to other [http://www.rootsimple.com/2014/06/whats-the-best-solar-food-dryer/ indirect solar dehydrators]). The top hole can also be partly closed -this is accomplished by a wooden block that has been given a nut/bolt in one corner, allowing it to swivel opn/closed&lt;ref&gt;This is similar to the Dick Strawbridge solar dryer&lt;/ref&gt;). Inlet air holes are made in the solar thermal collector. <br /> <br /> The design of this solar thermal collector is similar to other indirect solar collectors -so just a basic flat panel solar thermal collector consisting of glass, an open wooden box and a flat, black sheet of metal. Special about this solar collector however is the addition of a fine wire heat exchanger (marked with D2) attached to the back of the flat, black sheet of metal (marked with B). This heat exchanger comes to outside the wooden box, allowing to be heated by an oil burner (marked with D1). The solar thermal collector is also fitted with 2 nuts and bolts (marked with C), allowing it to be rotated for optimal efficiency for your location/time of the year. See http://www.appropedia.org/File:Solar_energy_harvester_orientation.png<br /> <br /> The solar thermal collector goes into a wooden box (marked with G) at the bottom of the dehydrator. This box is made of 4 wooden panels, of which the top wooden panel is perforated, and a single hole is made in the bottom panel to allow the insertion of the solar thermal collector, while also allowing it to rotate a bit (so the hole is larger than what it needs to be). The box makes the bottom panel of the dehydrator redundant, so this was left out. The excess opening can be sealed by means of a rubber seal.<br /> <br /> Another major change is the door; this is no longer attached using hinges, but is now a sliding door (marked with J), being slided in from the top. 2 angle plates hold the door in place (hence function as a &quot;rail&quot;). They're marked with E. The door can be made to close more tightly by using 2 or 4 screw tighteners between the angle plates and the door (made of a threated plate and a bolt). Another special addition is a stop beam, marked with F; this beam makes sure the sliding door doesn't fall through downwards.<br /> <br /> Then the rest of the parts:<br /> * K: back wooden panel<br /> * H: metal mesh (note that these are not complete trays, so not framed), food comes on top of this. There is about 10 cm space in between the metal meshes<br /> * I: wooden strip, for metal meshes to rest on<br /> <br /> Note that no metal heat spreaders are necessary as space is left on both the front as the back of the metal mesh (the metal mesh is much less long as the wooden strips they rest on), creating a more equal heat spread throughout the entire dehydrator (see air circulation schematic). In Peter's design, this was an issue, and to counter this problem he advised to continuously rotate the position of the trays. This is however cumbersome and might no longer be needed with the current design (although the top trays will probably still get more heat than the bottom ones). If this still remains a bit of a problem, try using 2 types of food, the top food trays then being used for food that needs more dehydration than the food placed on the bottom trays. Another option is to simply not fill it completely (using only the bottom or top trays instead) or to build a less high version of this dehydrator (with less trays). In many cases, you'll probably want to use timber you allready have, reuse old existing cabinets, ... so you'll probably end up making a custom version of this dehydrator anyway.</div>

The top hole can also be partly closed -this is accomplished by a wooden block that has been given a nut/bolt in one corner, allowing it to swivel opn/closed&lt;ref&gt;This is similar to the Dick Strawbridge solar dryer&lt;/ref&gt;). Inlet air holes are made in the solar thermal collector. <br /> <br /> The design of this solar thermal collector is similar to other indirect solar collectors -so just a basic flat panel solar thermal collector consisting of glass, an open wooden box and a flat, black sheet of metal. Special about this solar collector however is the addition of a fine wire heat exchanger (marked with D2) attached to the back of the flat, black sheet of metal (marked with B). This heat exchanger comes to outside the wooden box, allowing to be heated by an oil burner (marked with D1). The solar thermal collector is also fitted with 2 nuts and bolts (marked with C), allowing it to be rotated for optimal efficiency for your location/time of the year. See http://www.appropedia.org/File:Solar_energy_harvester_orientation.png<br /> <br /> The solar thermal collector goes into a wooden box (marked with G) at the bottom of the dehydrator. This box is made of 4 wooden panels, of which the top wooden panel is perforated, and a single hole is made in the bottom panel to allow the insertion of the solar thermal collector, while also allowing it to rotate a bit (so the hole is larger than what it needs to be). The box makes the bottom panel of the dehydrator redundant, so this was left out. The excess opening can be sealed by means of a rubber seal.<br /> <br /> Another major change is the door; this is no longer attached using hinges, but is now a sliding door (marked with J), being slided in from the top. 2 angle plates hold the door in place (hence function as a &quot;rail&quot;). They're marked with E. The door can be made to close more tightly by using 2 or 4 screw tighteners between the angle plates and the door (made of a threated plate and a bolt). Another special addition is a stop beam, marked with F; this beam makes sure the sliding door doesn't fall through downwards.<br /> <br /> Then the rest of the parts:<br /> * K: back wooden panel<br /> * H: metal mesh (note that these are not complete trays, so not framed), food comes on top of this.<br /> * I: wooden strip, for metal meshes to rest on<br /> <br /> Note that no metal heat spreaders are necessary as space is left on both the front as the back of the metal mesh (the metal mesh is much less long as the wooden strips they rest on), creating a more equal heat spread throughout the entire dehydrator (see air circulation schematic). In Peter's design, this was an issue, and to counter this problem he advised to continuously rotate the position of the trays. This is however cumbersome and might no longer be needed with the current design (although the top trays will probably still get more heat than the bottom ones). If this still remains a bit of a problem, try using 2 types of food, the top food trays then being used for food that needs more dehydration than the food placed on the bottom trays. Another option is to simply not fill it completely (using only the bottom or top trays instead) or to build a less high version of this dehydrator (with less trays). In many cases, you'll probably want to use timber you allready have, reuse old existing cabinets, ... so you'll probably end up making a custom version of this dehydrator anyway.</div>

<p>VDP: </p> <hr /> <div>Sketch for a low-cost house design for disaster areas/refugee camps. The designed down shelter has been mainly inspired/based on the &quot;straw<br /> bale temporary structure&quot; mentioned in the Earthship Volume 3 book by Michael Reynolds (and also on the circular Haiti home (see<br /> inhabitat.com/earthquake-resistant-earthships-for-haiti-disaster-relief/ to and the Hurricane Home (see Earthship volume 3) to some extend). It has been made simpler by making it much more like a regular storm shelter (hence completely dug out in the soil rather than earth-bermed). In regions with unstable soil (sandy soil, ...), the walls (earth cliffs) need to be excavated as well and replaced with earth bags filled with sand, compressed earth, ... <br /> The design can only be used in reasonably dry soil. Straw bales may be needed in some cases (colder areas) to provide additional insulation. The roof is a plastic plate to provide sufficient light (daylighting). There is no insulation below this roof.<br /> <br /> To avoid needing to build below ground level, and to eliminate water problems, a double berm can was used (this is similar to the Hurricane Home. Earthbags were used between the berms and the straw bales to avoid needing to load the straw bales (to mount the roofing).<br /> <br /> Perhaps that it might be suitable to use natural rubber (latex) or<br /> vulcanised rubber bags to shovel the earth in. This makes it more<br /> similar to a regular earthship and more earthquake resistant. Also,<br /> rubber doesn't degrade easily (atleast far less than natural textile).<br /> <br /> Regarding the material of the bags: obviously this should be a natural<br /> material, as the idea is to build a 100% natural house. If vulcanised<br /> rubber isn't available, natural rubber can be used and or vulcanised<br /> on-site (I assume this is done with non-artificial products). You also found a variant of the building on the right. It uses no bags at all but<br /> simply a plywood board (on pressed against both berms). I got the idea<br /> from regular rammed earth construction (see<br /> http://www.iagram.com/rammedearth.jpg )<br /> <br /> See also<br /> * http://www.naturalbuildingblog.com/straw-bale-dome-home-in-france/<br /> * http://www.naturalbuildingblog.com/straw-bale-roundhouses-built-in-one-day/<br /> <br /> ==License==<br /> {{GFDL}}</div>

The image was made based on an image in the book &quot;Practical self-sufficiency by Dick and James Strawbridge&quot;<br /> <br /> Producing biodiesel so as to use it in an unmodifyied (modern) Diesel engine is much simpler than converting Diesel engines to run on SVO/WVO (requires changing to indirect injection, heating the fuel, ...) It involves following steps:<br /> <br /> # making the mixture by combining the catalyst with ethanol or methanol. When using potassium hydroxide as the catalyst, you need about 3g per litre of WVO. For the alcohol: when using methanol, you need about 20% of the volume of WVO<br /> # adding mixture to SVO/WVO in biodiesel reactor<br /> # heating SVO/WVO + mixture to 60°C using an immersion heater and circulate it (done in a biodiesel reactor)<br /> # leave to stand for 6 hours (no circulation)<br /> # drain the glycerol which has formed and sunk to the bottom<br /> # wash the SVO/WVO + mixture with water in a tank with a fish tank aerator (bubble washing). This is done by adding 1 part water to every 2 parts biodiesel and then turning on the aerator.

<p>VDP: </p> <hr /> <div>==Overview==<br /> The [[GVCS]] list is currently locked at 50. Though additions are welcomed to be researched for later integration (after completion of the GVCS 1.0).<br /> <br /> See [[Adding a GVCS Tool]] for more information.<br /> <br /> ==Proposed tools==<br /> *'''Loader''' - an attachment for the [[LifeTrac]] tractor<br /> <br /> *'''Village-scale washing machine''' - powered by the universal rotor<br /> <br /> *'''[[Fridge]]'''<br /> <br /> *'''Reversible heat pump''' - for controlling the temperature of homes and greenhouses, refrigerating food and medicine, harnessing solar and geothermal heat, see File:HeatAndColdStorageWithHeatPump.png<br /> <br /> *'''[[Stirling engine]]''' - transforms heat into mechanical energy<br /> <br /> *'''[[Spectrometer]]''' and '''computer oscilloscope''' - adding these to the GVCS would form a complete Fab Lab. Most of the work will be done by other open-source groups.<br /> <br /> *'''[[Juice Press]]''' - A horizontal screw (juice) press powered by the [[Power Cube]]; a continuous screw press design could also prove valuable, ie for pressing canola, olives, ...<br /> <br /> *'''[[Log Splitter]]''' - A log splitter powered by the [[Power Cube]].<br /> <br /> * a solar thermal collector; based on the [http://www.appropedia.org/Zaragoza_Solar_Hot_Water_System Zaragoza SHWH] with [http://www.appropedia.org/Talk:Solar_hot_water#Tank_placement modifications]<br /> <br /> * a large biodiesel reactor<br /> <br /> * a large still (for production of ethanol); can be similar to [http://www.turbosquid.com/3d-models/fractionating-column-3d-model/726392 this] or be based on a Journeytoforever or Motherearth design<br /> <br /> * a solar still either similar to [http://www.turbosquid.com/3d-models/seawater-solar-plant-distillation-3ds/727791 this] or based on the Zonnewater B.V. stills. Both designs use an electrical heater and the second design uses a PV panel. This means that besides better efficiency (as heating/cooling is seperated), the design can also be used when the sun doesn't shine by using electrical power from other renewable energy sources. <br /> <br /> * a large biogas production plant<br /> <br /> * production plants of other emissionless fuels, for example biobutanol and nitrous oxide (see [http://www.appropedia.org/Comparison_of_alternative_ICE_fuels appropedia link 1] and [http://www.appropedia.org/ICE_fuel_generator appropedia link 2])<br /> <br /> * a compressed air energy storage system; a small scale system like this doesn't exist yet, should be similar to [http://www.turbosquid.com/3d-models/3d-model-compressed-caes/727270 this design]<br /> <br /> [[File:CAESUS for vehicles.JPG|thumb|right|CAES&amp;US system for use in vehicles]]<br /> * For the GVCS car, see the image at the right and the description. I think that experience gained with this idea would be useful for the compressed air energy storage system mentioned above. The file description was previously at appropedia.<br /> <br /> [[File:Strawbridge heat sink.JPG|thumb|right|Strawbridge heat sink]]<br /> * The Strawbridge heat sink can be added (I modified this from Strawbridge's original design). See image on the right. The file description was previously at appropedia (http://www.appropedia.org/Growing_under_cover )<br /> <br /> * For the 3D printer, I think you best swap the RepRap design with the ORDBot design (http://www.appropedia.org/Open_source_3-D_printers#List_of_open_design_3-D_printers ) It's stronger and I think with some thinkering you could print more materials (perhaps including metal)<br /> <br /> * Besides the seeder, perhaps include a wheeled auger (similar to http://users.skynet.be/sb021277/Pages/Nederlands/Pflanzfuchs/PF.html ) or even better, just make a 2-wheel tractor that can be fitted with an auger. The auger is a cheap tool to allow 2 people to seed quickly, and also allows other uses (ie making holes for construction, ...) The 2-wheel tractor can be based on the BCS 722. Also, it's best to have the 2-wheel tractor electrified, so it can be powered by a stationairy engine running on a biofuel (straight vegetable oil). A tractor with IC engine is possible, yet requires modification so it can run on a biofuel so it's easier to do it this way. <br /> <br /> * swap the spader with a regular rototiller but just make that rototiller easier to fabricate/cheaper. You could also make a version adapted for use on the traction engine design I made (a light vehicle such as this requires less fuel to operate the implement). A spader isn't any better (actually worse in my view as the soil isn't cut up as much. No-till is all the rage these days (see http://www.betuco.be/CA/No-tillage%20Farming%20for%20Sustainable%20Development.pdf ), but really it isn't absolutely necessairy, rather we just need equipment that is much more precise, for example rototilling only upto the depth required for planting (and not more). So make the depth settable. Even better would be to only cut up the soil exactly where you plant, so leaving the interrow-sections unaffected, however that's difficult to accomplish.<br /> <br /> * you also seem to not have many specialized agricultural tools, for example for harvesting fruit from orchards. For harvesting olives/nuts from trees, shakers/vibrators are for example used that clamp on the tree and shake off the olives/nuts. For collecting the fallen off produce, tarps on rolls are sometimes used (tarps being rolled up automatically, sliding the produce off into a bin). An other approach is by using disc brushes (round rotating brushes as used in municipal services to clean up litter from streets)<br /> <br /> ==See Also==<br /> *[[GVCS]]<br /> *[[OSE Spec]]<br /> <br /> <br /> [[Category: GVCS]]</div>

The designed down shelter has been mainly inspired/based on the &quot;straw<br /> bale temporary structure&quot; mentioned in the Earthship Volume 3 book by Michael Reynolds (and also on the circular Haiti home (see<br /> inhabitat.com/earthquake-resistant-earthships-for-haiti-disaster-relief/ to and the Hurricane Home (see Earthship volume 3) to some extend). It has been made simpler by making it much more like a regular storm shelter (hence completely dug out in the soil rather than earth-bermed). In regions with unstable soil (sandy soil, ...), the walls (earth cliffs) need to be excavated as well and replaced with earth bags filled with sand, compressed earth, ... <br /> The design can only be used in reasonably dry soil. Straw bales may be needed in some cases (colder areas) to provide additional insulation. The roof is a plastic plate to provide sufficient light (daylighting). There is no insulation below this roof.<br /> <br /> To avoid needing to build below ground level, and to eliminate water problems, a double berm can was used (this is similar to the Hurricane Home. Earthbags were used between the berms and the straw bales to avoid needing to load the straw bales (to mount the roofing).<br /> <br /> Perhaps that it might be suitable to use natural rubber (latex) or<br /> vulcanised rubber bags to shovel the earth in. This makes it more<br /> similar to a regular earthship and more earthquake resistant. Also,<br /> rubber doesn't degrade easily (atleast far less than natural textile).<br /> <br /> Regarding the material of the bags: obviously this should be a natural<br /> material, as the idea is to build a 100% natural house. If vulcanised<br /> rubber isn't available, natural rubber can be used and or vulcanised<br /> on-site (I assume this is done with non-artificial products). You also found a variant of the building on the right. It uses no bags at all but<br /> simply a plywood board (on pressed against both berms). I got the idea<br /> from regular rammed earth construction (see<br /> http://www.iagram.com/rammedearth.jpg )<br /> <br /> See also<br /> * http://www.naturalbuildingblog.com/straw-bale-dome-home-in-france/<br /> * http://www.naturalbuildingblog.com/straw-bale-roundhouses-built-in-one-day/</div>

<p>VDP: </p> <hr /> <div>== Summary ==<br /> Schematic of a compressed air energy storage (and use) system for vehicles. The first system is a variation of the Proe compressed air system (see http://www.proepowersystems.com/ ) in which one modest change was done: an air tank was added; the parts were also arranged a bit simpler.<br /> <br /> The second system shows a system designed by KVDP in which the compressor does not work on the stack effect like Proe's system, but rather uses a Beta-type Stirling engine (see [http://www.turbosquid.com/3d-models/3d-model-internal-combustion-motor-2/727584 the Stirling engine used in this system]). The main advantage of this is that a more powerful compressor type can be used (ie rotary vane compressor or even screw compressor -the latter is rather expensive though-) and that this compressor can also be used to recharge the compressed air tank. Another advantage is that the burner should use the heat more effectively (Proe's system could potentially waste much more energy in the form of heat). A major downside to Proe's system is the greater complexity, and the fact that an oil tank is needed, which means a possibly greater weight in comparison to Proe's system, also it may be less compact.<br /> <br /> The compressed air tanks are added in both systems mainly to allow the vehicle to be started right away, without a (15 min) warm-up time. <br /> <br /> The reason that a hybrid (compressed air/biofuel) system is useful is because the energy density of biofuel is much higher than that of compressed air, in addition it also doesn't need a (heavy) tank. An automated pellet burner (or an automated burner burning standardised wooden blocks) can be used.<br /> <br /> == Licensing ==<br /> {{GFDL}}</div>

The auger is a cheap tool to allow 2 people to seed quickly, and also allows other uses (ie making holes for construction, ...) The 2-wheel tractor can be based on the BCS 722. Also, it's best to have the 2-wheel tractor electrified, so it can be powered by a stationairy engine running on a biofuel (straight vegetable oil). A tractor with IC engine is possible, yet requires modification so it can run on a biofuel so it's easier to do it this way. <br /> <br /> * swap the spader with a regular rototiller but just make that rototiller easier to fabricate/cheaper.

The file description was previously at appropedia (http://www.appropedia.org/Growing_under_cover )<br /> <br /> * For the 3D printer, I think you best swap the RepRap design with the ORDBot design (http://www.appropedia.org/Open_source_3-D_printers#List_of_open_design_3-D_printers ) It's stronger and I think with some thinkering you could print more materials (perhaps including metal)<br /> <br /> * Besides the seeder, perhaps include a wheeled auger (similar to http://users.skynet.be/sb021277/Pages/Nederlands/Pflanzfuchs/PF.html ) That's a cheap thing to allow 2 people to seed quickly, and also allows other uses (ie making holes for construction, ...)<br /> <br /> * swap the spader with a regular rototiller but just make that rototiller easier to fabricate/cheaper. You could also make a version adapted for use on the traction engine design I made (a light vehicle such as this requires less fuel to operate the implement). A spader isn't any better (actually worse in my view as the soil isn't cut up as much. No-till is all the rage these days (see http://www.betuco.be/CA/No-tillage%20Farming%20for%20Sustainable%20Development.pdf ), but really it isn't absolutely necessairy, rather we just need equipment that is much more precise, for example rototilling only upto the depth required for planting (and not more). So make the depth settable. Even better would be to only cut up the soil exactly where you plant, so leaving the interrow-sections unaffected, however that's difficult to accomplish.<br /> <br /> * you also seem to not have many specialized agricultural tools, for example for harvesting fruit from orchards. For harvesting olives/nuts from trees, shakers/vibrators are for example used that clamp on the tree and shake off the olives/nuts. For collecting the fallen off produce, tarps on rolls are sometimes used (tarps being rolled up automatically, sliding the produce off into a bin). An other approach is by using disc brushes (round rotating brushes as used in municipal services to clean up litter from streets)<br /> <br /> ==See Also==<br /> *[[GVCS]]<br /> *[[OSE Spec]]<br /> <br /> <br /> [[Category: GVCS]]</div>
