Jung-Chih Chiao is an electrical engineering professor and he decided to make very tiny windmills. They are only 1.8 mm in diameter! They are made from a type of flexible nickel called alloy and a single wafer. Researchers are thinking that they might sell them in packs of 100 for emergency cell phone chargers. A few thousand could power the communication, security, and lighting of a house. It won't be long before the micro windmills are on the market.
