Febot mini wind turbine charges up a battery right outside your window

Check out this wind-powered battery charger. Febot is a design concept for charging up a single AA battery, where you attach its suction cup outside a window of your house or car, and the tiny generator uses the power of the wind to give you all-free energy as long as the wind blows.

We usually think of huge wind turbines cranking out the megawatts, but Febot taps into wind power on a comparatively micro scale. It's this kind of innovative thinking that will usher in the new age of completely renewable energy.
