Charge up your gadgets with pedal power while you bike

Here's a clever trick: using the energy generated by you pedaling your bike to charge up your phone or audio player. Dalton's BioLogic FreeCharge does just that, hooking up to your bike's generator hub and creating power to juice up any USB gadget you have on hand. Look for it in March 2010 for $100.
