Sure you could wait a few months and get one of those fancy hydrogen fuel cell cars coming from Japan, or you could get some fresh air with the Pearl fuel cell bike from Valeswood right now. Instead of pedaling yourself up hills and along the highways, the Pearl helps you out by giving you the extra oomph when needed. Best of all, the only byproduct is water, making this one eco-friendly bicycle.

With a top speed of 15 miles-per-hour and a range of 80 miles, you probably won't have to recharge the two storage canisters that often, but if you find yourself in the middle of nowhere and you're too tired to pedal yourself home, the bike folds in half for easy storage in a car trunk. The bad news? The Pearl sells for $4,000, which might make you think twice about power assisted bicycles. — Stephen Schleicher
