Vertical wind turbine with two concentric rotors Physics
Jun 19 2019 · An interference pattern between two concentric rotors would minimize the drag produced by the wind as the blade is traveling against the direction of the wind on the opposite side of the vertical wind turbine. (a drawback of a conventional vertical wind mill design) I had a dream about this wind turbine once a vision stuck in my head since.

How Do Wind Turbines Work Department of Energy
A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades which work like an airplane wing or helicopter rotor blade. When wind flows across the blade the air pressure on one side of the blade decreases. The difference in air pressure across the two sides of the blade creates both lift and drag.
