The solar updraft tower is a way to harness solar power . Air in a very large greenhouse-like structure is heated by sunshine and rises up a chimney. The flow of air drives turbines which produce electricity. A research prototype was created in Manzanares, Spain in the 1980s, by the German engineer Jörg Schlaich, and many modelling studies have been published as to optimization, scale, and economic feasibility. In December 2010, a solar updraft tower in Jinshawan in Inner Mongolia started operation, producing 200 kilowatts of electric power. A company called EnviroMission proposed to build a large solar updraft tower in Australia but never completed the project. Now it has announced plans to build two 200 megawatt towers in western Arizona.
