Tower of Power
The Australians are planning to build the world's largest solar heater. Oh, and it will also be the world's tallest structure at 3,280 feet, more than twice the height of Malaysia's Petronas Towers. The Solar Tower will be located on a 25,000 acre sheep station (Australian for ranch) in the outback. The tower will work by heating air inside the structure using just the region's normally blistering climate. The heated air will rise up like in a chimney, turning turbine blades to produce electricity. Like a vertical wind-farm, without the need for wind. Arrangements have already been made to fit the tower with special high-intensity lights to keep airplanes away.
