Rechargeable batteries are a boon to mankind as it helps save the environment and money simultaneously, although the recharging period can be quite a pain in the rear end if you need instant juice. The Febot concept makes recharging a whole lot more fun, as this easy-to-assemble device features a torpedo-like design which you place the AA battery inside. It will then rely on energy created by wind around to move its propeller, using such kinetic energy and translating it into pure, unadulterated juice. All you need to do is stick the Febot out the window and leave it alone. Works best in high buildings since the higher floors are really windy, and there is also the risk of having people nick this if you leave it out in your backyard.
