Abstract: The present invention provides a system of wind turbines connected to a single unit electric generator to produce electrical power whereby the wind turbine blades rotate coaxially with a main rotor shaft instead of perpendicular to the shaft axis. In this respect, the wind turbine rotor can face the wind from any direction and does not need to be pointed into the wind to be effective, thus, eliminating the need for a yaw system. Moreover, translation of mechanical to torque of the main rotor drive allows the drive components such as the gearbox and generator to be placed near the ground of each wind turbine improving accessibility for maintenance.
