Video: World’s tallest building could be a 24/7 Australian solar chimney

By | January 26, 2012, 8:34 AM PST

Bad news for Dubai’s 829-meter high Burj Khalifa. It might lose its distinction as the world’s tallest building, if a bunch of hot air takes root as planned in Australia.

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:

I see...
They are creating an atmosphere heater... transfer ground heat into the atmosphere more quickly than natural processes.

All at a start-up price of $8,500,000 per MegaWatt... not counting maintenance and distribuiton costs.

No - a funnel!
Same principles work in hydroelectric dams.

should have tried the "heat chimney"
400 mw for approx. 1 bln dollars. cheap!

Seen that once.
It had been proposed in southern California back in the 1980s.

Water being used for irrigation was to be diverted to the tower. It was anticipated a natural rain shadow would happen down wind of the tower replacing the need for irrigation.

The big question.
Will the stack be tall enough for effective use? This will be a fun project to watch.

".62-mile high shoot"
Would not 'chute' work better?

Didn't We See This Before???
Didn't we see this before? Planned for Arizona, I believe. Same group proposed it.

It still has the same problems. Very high tower, large ground installation, Wind Shear, high enough to have different wind directions blowing in different directions, and so forth.

Still, all of those problems COULD be taken care of. It's after all just an engineering problem. But it will take more than just a simple stack. There will be a lot of stress in the lower column.
