The Solar Chimney
To be built in Austrailia, SolarMission Technologies "are developing the world's first commerical Solar Tower (aka Solar Chimney)." The Solar Chimney will be able to generate 200MW of electricity equaling enough power to roughly 200,000 households. The construction of this very tall tower (2 1/2 times taller than the Empire Stte Building) "will take almost three years, almost 3,000 contruction workers, and just 15 employees required to supervise, run and maintain the completed site." The solar tower is expected to reduced carbon dioxide "emmisions by almost 1 million tonnes per year compared to a 200MW brown-coal powered generator."
