Hot air power.

Today's Guardian reports:

"A one kilometre-high tower capable of producing enough energy for 200,000 homes has been approved by the Australian government (...)"

"In effect a giant chimney, it will generate electricity by drawing warm air from ground level through turbines."

"The concrete tower will be (...) almost twice [as high as] the 555-metre CN tower in Toronto."

Fascinating.
