The wind is moving air! When warm air rises through the atmosphere, cool air flows in to take its place, creating wind! Did you know that wind power can produce electricity? Tall machines called wind turbines are solar-powered and becoming the fastest-growing renewable source of energy–they burn no fuel and cause no pollution. Turbines can be found on many wind farms, especially in Europe!

Learn what wind does, how the wind can vary in strength from gentle breezes to hurricanes and tornadoes, and how the wind can help us.

And when he served in the Army Air Corps during WWII, Vollis kept right on tinkering. His ingenuity allowed him to build things no one would have thought to create from scraps—a washing machine out of airplane parts and a motorcycle out of a bike. After the war, his passion for metal creations picked up speed—turning into a whirlwind of windmills as far as the eye could see.
