Abstract
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 population that live in rural areas where roof-top wind turbine will be cost effective to provide enough household required electric power. This compact turbine can also use batteries to store energy, thereby reducing and possibly eliminating the need for grid power.
