Overview[edit]

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).

See Adding a GVCS Tool for more information.

Proposed tools[edit]

  • Loader - an attachment for the LifeTrac tractor
  • Village-scale washing machine - powered by the universal rotor
  • Fridge; see File:Walk in cooler with thermal mass and outdoor cooling.png
  • A natural house, see File:OD natural house.JPG
  • Reversible heat pump - for controlling the temperature of homes and greenhouses, refrigerating food and medicine, harnessing solar and geothermal heat, see File:HeatAndColdStorageWithHeatPump.png
  • 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.
  • 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, ...
  • a large biodiesel reactor, see File:Biodiesel reactor.JPG and File:Filtering WVO.png
  • a large still (for production of ethanol); can be similar to this or be based on a Journeytoforever or Motherearth design
  • a solar still either similar to 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.
  • a large biogas production plant
  • a compressed air energy storage system; a small scale system like this doesn't exist yet, should be similar to this design for optimum efficiency. A more simple device can however be build by just combining a store-bought air compressor with large integrated tank with a rotary vane pump, and an alternator for producing 220V, 50-60 Hz. This device, though much less energy-efficient, would still be quite useful for coping with mains electricity grid power outtages, as electricity can be convererted to compressed air energy at periods when the mains electricity grid does have power and used when no electricity is available on the grid. The system could be connected to a net metering installation for ease of use.[1]
CAES&US system for use in vehicles
  • 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.
Strawbridge heat sink
  • 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.
  • 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.
  • 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)
