A hybrid vertical axis wind turbine using a highly aerodynamic blade-profile is disclosed. The blade-profile is simple, asymmetrical with unequal upper and lower surfaces cambers and is capable of generating high starting torque even at low wind. Wind tunnel tests demonstrated that this aerodynamic profile would generate high torque of similar magnitude when wind comes from leading or trailing edge. Other characteristics of this profile are that it is compact, lightweight, durable and economical. The target users for this patent will be 44% of the world ...
1. A hybrid vertical axis wind turbine structure comprising: a vertical rotating shaft at the center of the turbine; an upper hub and a lower hub to accept a set of upper horizontal beams and a set of lower horizontal beams at one end of the horizontal beams wherein the horizontal beams are formed in the shape of a semi-circular hollowed cylinder to capture wind; multiple blades each connected to the ends of the upper horizontal beam and the lower horizontal beam on the opposite end of the horizontal beams connecting to the hubs; a near end of the horizo...
