Wind turbine direct drive alternator system includes a supporting structure, at least two turbines mounted on the supporting structure to rotate in opposite directions when exposed to the same wind, a respective number of alternator rotor disks whereby each turbine is directly connected to an alternator rotor disk, and a stator unit having two sides each facing a respective rotor disk. The stator unit is arranged or constructed such that torque generated by rotation of each turbine can be transmitted therethrough with a view toward balancing the torque induced on the supporting structure by rotation of the turbines. When the stator unit includes two stator disks, each stator disk transmits approximately the same magnitude of torque as, but in an opposite direction to, the other stator disk. The two stator disks balance the torque of each other and almost no external torque is needed to balance the system.
