Several years ago I was traveling around Germany and saw hundreds of wind
mills with the blades stationary. Same thing here in the US.
If you are going to pollute the visual environment with wind mills you might
as well make them work. I suggested to my German friends that they construct
a mine shaft into the ground and hollow out an under ground water reservoir.
You also need a lake or large tank above ground to store the water when
the wind blows.

Now.... remove the generator in the wind mill and replace it with a simple mechanical
pump. Much lower cost and far more reliable than a geared generator. Over 100 year
old technology.

Now use a water turbine below ground to generate the electricity when
the wind is not blowing and release the water in the above ground lake.

This Canary island did almost that.
