Patent abstract
A wind turbine has a hub mounted on a rotatable shaft with a ring concentrically mounted on the shaft. The ring is connected to drive wheels, which in turn drive generators to produce electricity. A controller is connected to control the speed of the turbine by controlling the number and force of contact between the wheels and the ring and also controlling other components such as the pitch, yaw and brakes for the turbine while monitoring the wind conditions.
