I saw a CNN video on running a car on water over a year ago. I was also talking to a friend the other day and he told me about a video about "Who Killed the Electric Car." From what I understand, Chevy had started mass producing electric cars in the 90's, but would only lease them. The oil companies lobbied lawmakers to make the laws on electric cars so strict that it would end up being way too costly to continue making them. When the leases ended, Chevy could not renew any of the leases due to the new laws. Although the source I got this from is quite the conspiracy theorist, it is rather interesting. If I had more time on my hands at the moment, I would try to look a few things up.
