This patent-pending innovation in wind turbine technology involves two counter-rotating turbines connected through a novel drive train system. In this drive train, an "off the shelf" alternator is used to generate electricity, with one turbine used in the traditional manner to spin the alternator rotor while the second and counter-rotating turbine is used to spin the alternator stator by spinning the housing of the alternator. Testing data boasts a dramatic 30-35% increase in power output compared to traditional turbine arrangements, and decreases start-up wind speed to as low as 1 meter/second.
