Sure, it's an early prototype, but the rolling pile in this video may just be the key to the future. It's a car than runs on air, not gas.

Right now its top speed is 30 mph, and it only goes about three miles on a single, uh, fill-up, so to speak. But it's still early in the game.

Take a look. Do you think he's discovered something? Will the big oil companies squash this like a bug?
