solar car project

For the past several years I have been working on a solar powered car. It is not meant to be practical...more like a kind of test vehicle to try out ideas on. Anyways, now that I have a good sized bank of ultra-capacitors, I intend to try to experiment with them over x-mass break and see how they work on the car's power system. Because ultra-capacitors can charge much faster than batteries, they have the ability to recapture some of the energy lost through braking. By using the cars electric motor as a generator in the breaking action. Hybrid cars do this, but are only just starting to use ultra-capacitors.
