Healthy soil and sustainable growing

Right, but in areas were windmills have to be taken down often due to above 50mph winds, this windmill would be advantageous.  If you look at how it works, at higher winds it shuts itself to the wind and at lower winds it opens up.  Have friends in the windy plains of Montana that are looking at it.

Huh?

It's a Savonius wind turbine (VAWT), which, according to Wikipedia ( http://en.wikipedia.org/wiki/Savonius_wind_turbine):

[was] invented by the Finnish engineer Sigurd J Savonius in 1922.

...

Because they are drag-type devices, Savonius turbines extract much less of the wind's power than other similarly-sized lift-type turbines. Much of the swept area of a Savonius rotor is near the ground, making the overall energy extraction less effective due to lower wind speed at lower heights.
