Patent ID: RE43014

Claim:
A wind turbine assembly for mounting atop a building, comprising: a support assembly configured to mount atop a building, in proximity to a parapet of the building, wherein wind directed at a side of the building flows over the parapet to create an enhanced wind region above the parapet and a wind shadow behind the parapet; and a rotor assembly including a rotor coupled to an electric generator to generate an electrical current; wherein the rotor includes an elongated hub and a plurality of blades disposed about the hub; and wherein the rotor assembly is mounted to the support assembly in such a manner that wind flowing over the parapet interacts with the blades to cause the rotor to rotate about the axis of the elongated hub, with the blades disposed in an upper portion of the rotor's rotation disposed in the enhanced wind region and with the blades disposed in a bottom portion of the rotor's rotation disposed in the wind shadow of the parapet.
