Air rotor system

Magenn Power aims to use a helium-filled blimp with curved fins to harness winds at altitudes between 180 and 300 metres. The fins cause the aircraft's midsection to spin, rotating generators at each end. The company flew a 3 by 7 metre prototype in 2006.

Looks better than normal windpower with blades that has placed (birds and other species) in danger.

@Signzit actually the wind basically slows downs after the mesosphere

A 1.5 MW generator for a normal tower mounted wind turbine weighs 7.5 ton and the gearbox to step up the speed off the blades weighs 16.2 ton plus a 50 ton Nasal to hold it all together.

So these blokes propose lifting 75 ton plus the weight of the blades on a kite?

I'd want to stay WAY out of the fall raduis of that thing.

that high or even higher the wind never stops.

I would fly it as high as the law would allow.

does anyone want a eyesore like that in the garden!

Same way that helicopter blades can turn without rotating the rest of the helicopter.
