A promising design in wind turbines has recently been developed by Iowa State Aerospace engineers Hui Hu and Anupam Sharma. After exploring the idea of adding a smaller secondary rotor to an existing wind turbine, a more efficient energy output can be harnessed from the wind.

A further scientific analysis has challenged an assertions of the anti-wind organization – that indistinct sound waves (or infrasound) produced when operating wind turbines is directly linked to disease.
