500 Miles on a 5 Minute Charge

Texas start-up EEStor, has capacitors that can store huge amounts of charge, and release it in a relatively controlled fashion, have already started showing up in hybrid cars, but EEStor seems to have taken this further. They claim to have an ultracapacitor that can store enough power to drive a car 500 miles. Not only are ultracapacitors entirely free of toxic substances, they can be charged extremely quickly and never lose capacity. EEStor is already licensing the technology to Toronto based Feel Good Cars (http://www.feelgoodcars.com/) and they should be on the road by 2008. Soon after, we could see them in larger vehicles, as well as portable electronic devices. (via: http://www.ecogeek.org)
