Wind turbine apparatus

A wind turbine apparatus comprising a shaft, a first wind turbine, a second wind turbine, and a two-piece alternator, the shaft having a longitudinal axis, the first wind turbine, the second wind turbine and the alternator being mounted on the shaft, the alternator being located between the first wind turbine and the second wind turbine, the alternator comprising (a) a circular magnet component fixed to the first wind turbine, and (b) a circular winding component fixed to the second wind turbine so that, when an effective wind blows in a direction perpendicular to the longitudinal axis of the shaft, (1) the first wind turbine and the circular magnet component will rotate around the shaft in a first direction and (2) the second wind turbine and the circular winding component will rotate around the shaft in a second direction opposite the first direction, thereby generating electrical energy.
