Patent ID: 7887284

Claim:
A turbine powered by wind comprising a rotor on a shaft, said rotor having blades extending outward therefrom, said blades being shaped to rotate said shaft when a velocity of said wind exceeds a predetermined minimum, said shaft being rotatably supported on a support that moves said blades in a yaw movement into and out of said wind as said wind changes direction, said turbine having a pitch adjustment mechanism to change a pitch of said blades, said shaft having a ring concentrically mounted thereon separately from said blades, said ring being longitudinally offset along said shaft from said blades, a plurality of rotators mounted to removably contact said ring, said rotators being connected to drive energy producing equipment, said rotators being constructed to rotate with said ring when said rotators are in contact therewith, thereby driving said energy producing equipment when said wind rotates said blades, a controller connected to control a speed of said turbine when a velocity of said wind exceeds a predetermined minimum by adjusting a force of each of said rotators that are in contact with said ring and to control each contact between each of said rotators and said ring independently.
