An ingenious backyard inventor has converted his old car into one that runs just using air. It's not using the pressurized air technology that others are using. This guy using a heating/cooling type of system. It's incredible what people come up with to solve problems.
While it may not work on highways yet, since it only goes 30 miles per hour, it certainly could get someone around town pretty easily...and super cheap. Want one?
