Wind turbine devices are presented that use counter rotating rotor assemblies 24, 34 in a horizontal axis wind turbine (HAWT) arrangement. This reduces the torque applied to the HAWT 10 thereby reducing the structural requirements of a wind energy generation system. Additionally, the counter rotating rotor assemblies 24, 34 cooperatively rotate an output shaft 50. In one arrangement, this shaft 50 is a vertical shaft which allows removing power generation equipment 60 from the axis of rotation of a HAWT to a position below the wind turbine and/or located on the ground. |
