This is a brilliant idea. It can be adapted to any road vehicle, and is cheaper than buying a whole new car. The balloon has fewer moving parts than an internal combustion engine, which means much lower maintenance costs. You don't even need tires, if you can tolerate a crunchy landing. If you have a rare car, and can't find that important scarce transmission part, no problem. And anyone who participates in hill climbs will have a huge advantage. Take that, Prius!
