Chances are you have quite a few spent AA batteries lying around. Probably because you played with your WowWee robots too much. Well, here’s an interesting concept for quick and easy re-charging of all your AA batteries.

The Febot is a design by Ji-yun Kim, Soon-young Yang and Hwan-ju Jeon out of Korea. It would be suction mounted to your window so it can catch the breeze and recharge your single AA inside. A pretty interesting solution. I have a feeling it may take a while though, unless you are in a hurricane.
