Title: Method and apparatus for generating electricity from a fixed pitch wind wheel

Abstract: A method and apparatus for generating electricity from wind energy, wherein a wind wheel is connected to drive an energy converter which effects a torque reaction on the wind wheel proportional to the square of the rotational speed of the wheel, so that the wheel may be operated at fixed blade pitch and the blade tip speed will be proportional to the wind speed. The wind wheel may be connected to drive an electric generator to generate electrical energy in synchronism with mains supply.
