	~~== Personal Rapid Transit (PRT) ==~~

	~~Have you guys seen this~~? http://en.~~wikipedia~~.org/~~wiki~~/~~Personal_rapid_transit~~		There are at least 17 open-source car projects out there. See the [http://p2pfoundation.net/Product_Hacking#Cars list at p2pfoundation]. Some of the more promising ones for Open Source Ecology:
			#'''Trev''' - lithium-ion batteries, two seats, very light. The car has been built and tested and the team are in the process of open-sourcing the designs [http://www.trevipedia.net/index.php?title=Main_Page here]
			#'''[http://www.cmmn.org/nc/en/home.html c,mm,n]''' (pronounced "common") - a Dutch open-source car project, one of the more active ones. It uses hydrogen fuel cells for storage and ultracapacitors to transfer energy to in-wheel motors.
			#'''[http://40fires.org/ Riversimple Hyrban]''' - Carbon fiber monocoque. Like c,mm,n, it stores energy as hydrogen and uses ultracapacitors to transfer it to in-wheel motors.
			#'''[http://www.edag.de/pr/press/pressemeldungen_2009/pm_20_01_2009/en EDAG]''' - [[Basalt fibers]] are used to make the body. Lithium-ion battery powers the car.
			#'''[http://www.theoscarproject.org/ OSCar]'''
			As you will notice, most of these are interested in hydrogen or battery energy, not biofuels. If we want a biofuel-powered car (which would fit better with the other GVCS tools), we can still use the designs for the body and other parts from the above projects.
