Fill the tube, slap the Febot on your window and your batteries will be recharged by wind power. This sleek, battery charger comes flat-packed, so you put it together.
A single AA battery fits snugly in the missile-shaped holder which has an attached propeller that spins in the breeze to collect energy. The entire unit sticks firmly on a glass surface with a suction cup. It is kind of cute and multiple mini wind generators would look fun in a group - good thing, we usually need to recharge more than one double A at a time.
The Febot concept was designed by Ji-yun Kim, Soon-young Yang & Hwan-ju Jeon.
