Fabergé of Wind

I had previously proposed offshore wind turbines with wind concentrators. Concentrating the wind has many benefits. The wind captured at higher altitude accelerates as it is directed downward due to air getting warmer at lower altitudes. Heat accelerates the air molecules. Additionally, like an avalanche effect the winds at different altitudes accumulate as they are pulled downward by the concentrator. Ideally, the concentrator should be concave. Therefore, sphere is an ideal shape for the concentrator which has the strongest structural strength. I had previously proposed tightened or loosened fabrics to concentrate the wind. This is technically not ideal because the fabric would get torn while flying freely with the wind. Instead, fabrics can be rolled and unrolled like in roller blinds. Each roller section would be controlled on the ground by cables. As the wind direction changes, different sections of the sphere would be closed to capture the wind. Therefore, no need for a wind synchronous giant rotating mechanism.

Such design has the benefit of generating almost constant electricity by adjusting the concentrator sections. Which is not possible with classical wind turbines. The giant electric generator would be placed on the ground which would reduce the installment and servicing costs. Additionally, very high powers can be generated without need for erecting extremely tall towers. Finally, the turbine would be much silent and can be placed close to a city center where the power is consumed.

A single giant sphere has the potential to power the whole city. In order to turn this giant sphere into a city symbol, I propose the frames and the fabrics to be painted. Just get inspiration by Fabergé Imperial Eggs.
