Using Solar Energy to Create Wind Power

Using Solar Energy to Create Wind Power

© Clean Wind Energy Tower A new type of wind power plant is in the works, and it is claimed to be able to produce clean energy from the sun and the wind with virtually no carbon footprint, fuel consumption, or waste production. And not only that, it purportedly uses heat from the sun to produce its own wind , which would make this new type of plant desirable in areas with low or inconsistent winds. The Clean Wind Energy Downdraft Tower is a skyscraper-sized hollow cylinder that uses the natural downdraft tendencies of air by spraying water (as a fine mist) across the top opening of the tower to cool the hot dry incoming air. As the water evaporates and cools the air, it becomes denser and heavier than the outside air, and then falls through the tower at speeds up to (and above) 50 mph. Once the faster moving air reaches the bottom of the tower, it is channeled through wind...
