just to let you guys know, the purpose of the wind shield is to get the maximum amount of wind to hit a key area at 90 degrees straight on.  Reducing the wind resistince for the lower half of the wind caching fins.  Kind of like a swamp cooler.  the bottom half of the shield would be curved down producing low pressure pulling the falling fins down.  This concept is kind of like a planes wings producing life yet instead of lift it would cause the turbine to spin up and over and down and back up fast!   what do you think

The returning blade will still offer resistance......a good idea though.
