Perth-based Hyperion Energy wants to build a kilometer-high “solar chimney” in the Western Australian outback, in partnership with German engineering firm Shlalch Bergermann. (Okay, so Saudi Prince Alwaleed bin Talal also has a 1,000 meter edifice in mind, as SmartPlanet’s Tuan C. Nguyen wrote in August. I guess what goes up keeps going up!).
The monumental scheme rests on the principle that hot air rises. A ground level canopy less than a millimeter thin and covering 3600 hectares would heat air that would escape up the .62-mile high shoot. Along the way, it would drive 32 turbines, with a total capacity of 200 megawatts - roughly the same as is often proposed for small modular nuclear reactors.
“The taller the tower and the bigger the collector, the more electricity is generated,” proclaims the Australian narrator in a Hyperion video promoting the CO2-free energy scheme (see below).
Hyperion believes the so-called “solar updraft tower” would provide much needed power to mining operations in western Australia, and could also connect to the grid. It hopes to go live by 2014. Recharge News says the company is currently seeking approval for the $1.7 billion plan.
Unlike many solar projects, this one would keep the generators humming day and night, as the ground continues to give off captured heat from dusk to dawn, Hyperion says. See for yourself:
