RollerGen uses pedal power to generate electricity

Remember the small little dynamo powered lights on the bike as kids? They would work great for as long as you were moving, and fast. High Tide Associates has upgraded this simple technology to generate power that can be stored to charge the portable electronics. RollerGen is a bike mounted generator that generates power as you pedal. Yes, thus it uses the principle of kinetic energy and stores and then charges your devices. It can spit out a whopping 30 watts that gets stored in a small battery called BOS (Bar of Soap). Priced at $495, personally I feel it is a tad too expensive, but useful nonetheless.
