Man-made tornadoes may produce green energy (PHOTOS)

Massive man-made twisters reaching to the skies from cyclopean structures on the ground may be the future of suburban landscape. A Canadian firm is developing the technology to use the tornadoes to produce electricity – and assures it would be safe.
The company, AVEtec Energy Corporation, is working on a proof-of-concept device after winning this month a grant from The Thiel Foundation, a non-profit organization created by PayPal co-founder Peter Thiel. The machine is meant to make a rotating column of air that sucks air from its base like a natural twister.
The company already built a four-meter diameter prototype and will now use the grant money to construct a version twice as big, which it hopes will produce a 40-meter tall vortex with a diameter of 30 centimeters.
