Micro windmills. As the windmills for wind farms get larger and larger, these go in the oppoite direction. Small isn’t only beautiful, it also seems to be efficient – if you can just make enough of them and put them to use all at the same time…

Innovative Wind Turbine Smaller Than a Penny Could Power Your Smartphone

The micro-windmills designed by electrical engineering professor Dr. J.-C. Chiao and research associate Smitha Rao are so tiny that a single grain of rice could hold about 10 of them, according to a news release from the university.

The duo envision embedding hundreds of micro-windmills in a sleeve for a cell phone. Users could generate electricity for the phone’s battery by waving it in the air or by holding it up to an open window on a windy day.

Thousands of turbines could be mounted on home or building walls to produce the energy needed for lighting, security, wireless communication and more.
