==c,mm,n==

The "c,mm,n" project is another open-source car project which actually made it to the prototype stage. http://www.cmmn.org [[User:Traroth|Traroth]] 01:50, 22 December 2011 (CET)

== OS vehicle ==

http://www.osvehicle.com/ is another open source car

==Changes to general OS car approach/Velocar==
I have a few more suggestions on how the design could possibly be improved even more :

* first, perhaps it's best to make the vehicle limited to a top speed of 45 km/ph, making it a "motorized quadricycle". No driving permit is then needed in Europe to drive it.

* one could mount the single wheel at the front, make this wheel steerable, and mount the 2 wheels on a non-rotatable axle with suspension at the back. This simplifies matters, makes turning easier and makes the vehicle more streamlined and have less wind resistance.
I think you should take a look at the CLEVER, which is also build this way (see [https://en.wikipedia.org/wiki/CLEVER here]). Adding a similar cage as the CLEVER would also increase safety, and make attaching of the shell easier/sturdier.

* a main reason why people use a car (instead of a bike, ...) is to get groceries from the supermarket. There's currently no storage room at all, so perhaps it's a good idea to include this so people can use it for groceries.

* perhaps that a small internal combustion engine can also be mentioned as the first choice, and an electric one as an alternative.
This internal combustion engine can be a non-powerful one, ie less than 10 HP, such as a lawnmower engine, ... and made to run on a biofuel (ie biobutanol or ethanol, ...)

Mounting the single wheel at the front and the double wheel axle at the back, and changing
the shell/adding a shell support/changing the shell design, and adding some additional space at the back (for groceries) could make the car much more popular, and increase safety and lower wind resistance, and make it a bit cheaper to produce. It should be easy to do as well, by keeping the existing components and simply changing the assembly procedure. Actually, it could be made modular even, having the user decide how to mount the wheels and have give him liberty to make his own shell design.

Proposed GVCS

2015-03-18T09:49:03Z

Thomas Xovady:

==Overview==
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==
*'''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

*'''Solar food dehydrator''' - see http://makezine.com/projects/solar-food-dryer/ and http://www.climatetechwiki.org/technology/jiqweb-edf and File:Food dehydrator (hybrid).png; an electric food dehydrator (using a hairdryer can also be made off course and be used even at rainy/cloudy days; oven's can also be used to function as a dryer -preheat the oven and then turn of before inserting food for drying-)

*'''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

*'''[[Stirling engine]]''' - transforms heat into mechanical energy

*'''[[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, ...

*'''[[Log Splitter]]''' - A log splitter powered by the [[Power Cube]].

*'''Beehives''', - see http://www.opensourcebeehives.net/, and http://en.wikipedia.org/wiki/Beehive_fence

* 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]

* 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 [http://www.turbosquid.com/3d-models/fractionating-column-3d-model/726392 this] or be based on a Journeytoforever or Motherearth design

* 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.

* a large biogas production plant

* 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])

* 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] 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.<ref>Planet Mechanics NGC documentary, episode: air-propelled motorbike</ref>

[[File:CAESUS for vehicles.JPG|thumb|right|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.

[[File:Strawbridge heat sink.JPG|thumb|right|Strawbridge heat sink]]
* 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 )

* 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)

* 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)
