Abstract
A wind turbine system to provide electrical power in areas not connected to the electrical power grid. The wind turbine system includes a frame and a rotatable shaft supported by the frame. A ring and idler gear assembly is coupled to the rotatable shaft. An upper rotor assembly is coupled to the rotatable shaft. The upper rotor assembly is configured to rotate in a first direction and thereby to rotate the rotatable shaft in a first direction. A lower rotor assembly is coupled to the ring and idler gear assembly. The lower rotor assembly is configured to rotate in a second direction which is opposite of the first direction and thereby to rotate the rotatable shaft in the first direction via the ring and idler gear assembly.
