Power your gadgets with a portable, miniature windmill

A couple of researchers at the University of Texas Arlington have come up with an even cool concept that you might use in the future to help charge your devices, and that is through the use of minuscule windmills that are apparently so tiny that you could fit about 10 of them on a grain of rice itself, meaning that it is also small enough where you could embed it into a phone, hold it up to a fan or just walk with it that it could potentially juice up your device.
