Hyperion Energy is looking to build a gigantic, kilometer tall tower in Australia. Where it really gets interesting is the ‘why’. The base of the two has holes in it. The land around it, for almost fourteen square miles, would be covered, creating an air gap between the ground and the cover. The sun would heat up the air under the cover, and hot air would rise up through the tower, drawing in cool air from the perimeter of the cover. Turbines installed in the base of the tower would be turned by the rising hot air, thus generating electricity. Perhaps the best part is since this operates on a temperature DIFFERENCE between the ground air and the air at the top of the tower, when night falls this will continue to generate electricity as the ground will retain heat while the air above the tower cools down. Natural power storage. So, not only is this clean, renewable energy, but…the plant pictured here would produce about as much electricity as as small nuclear reactor (200MW)! Awesome! They’re hoping to get this build and operational by 2014.
