a method of enhancing wind farm power production using hybrid wind turbine apparatus includes a pair of counter rotating rotors in tandem . an upright mast supports bearings underlying and rotatably supporting a hub assembly . a first set of rotor is mounted on the windward end of the generator shaft , while the second rotor is mounted on the downwind side of the generator shaft . three alternate approaches are used to increase power production of a wind farm . one approach uses two turbines assembled in tandem . the second approach uses a conventional high - speed induction generator powered by tandemly mounted contra rotating rotors using suitably designed gearboxes . the third approach uses a specially designed low speed direct drive induction generator powered by tandemly mounted contra rotating rotors without the need of gearboxes . thus , contra rotating wind turbines can be used to generate more electrical energy and revenue from the same wind farms .
