Wind efficiencies

Stormblade Turbine is More Efficient, Quietly Neighbor-Friendly – Gizmodo. ‘The prototype operates quietly in wind speeds from 7mph to 120mph, twice the range of conventional wind turbines, plus it’s a lot smaller and easier to maintain. Install two of them next to each other and they’ll look like a pair of eyes peering into the wind.’

Weird looking, but quiet and efficient. Like having a 747 bolted onto your roof.
