A wind motor includes a post (1) tower or other supporting structure, a bottom base (2) that supports at least one pair of shafts (4, 5), at least one rotor (6) on each of the shafts (4, 5), a mechanism for synchronizing the rotation of the rotors (6), a front shield (7) secured to the bottom base (2), an arrangement for the free rotation of the bottom base (2) with respect to the post (1), tower or supporting structure, at least one electric generator or another device for converting mechanical energy, driven by one of the rotor shafts (4, 5) or by the synchronizing mechanism, and an inertial body driven by the energy provided by the rotors.

An effective method to increase the efficiency of any vertical axis wind turbines attached to any stationary objects to generate electricity, Is to attach a reactive-shield system to the turbine. The reactive-shield system is any shield system that can change and align itself with the direction of the wind in real time. The system needs to be stable enough to always make the shield stay in front of the turbine once it is aligned with the wind. The shield shields most of the turbine front from the wind except the blade open facing the wind direction allowing it to experience the full force of the wind which increases the turbine efficiency, while shielding the blade spinning against the wind to experience no wind which reduces drag.
