Update on the Wind Concentrator

I had previously proposed a wind turbine with spherical wind concentrator. While I was thinking about the idea further, I recognized a problem. The air is less dense at higher altitude. Therefore, a wind hitting a wall would have more tendency to raise up instead of going down. As a result, the wind concentrator would converge the wind towards its top section not on its bottom. The wind turbine would need to be placed on top of the sphere. This would make the structure top heavy and increase its construction cost as well as maintenance cost. However, compared to traditional wind turbines, it is still easier to install a horizontal turbine which is supported in all directions.

I had also proposed a variant of these turbines that are only used as a kinetic energy source. The wind turbine on the top of the sphere would be designed to generate compressed air. The compressed air would then be directed towards the bottom via channels inside the spherical support structure. Then the machines on the ground would be driven by high pressure pneumatic systems.
