The Febot is a rechargeable battery concept that is basically a tiny windmill. The Febot sticks to any window or flat surface via a suction cup bottom. You place a single rechargeable battery inside it, and let the wind charge it up. The whole thing comes apart for easy portability and traveling. Created by Korean designers Ji-yun Kim, Soon-young Yang and Hwan-ju Jeon, the Febot is a great idea that could be adapted in many other ways like putting it on a bicycle to charge a headlight, or on boats, etc.
