ABSTRACT:
A wind turbine assembly includes a venturi passage and a rotor in proximity thereto for rotation about an axis lying substantially perpendicular to the venturi passage. A rotor chamber partially surrounds the rotor. A port communicates between the rotor chamber and a low pressure point of the venturi passage. A remaining exposed portion of rotor is rotated by wind forces pushing the rotor. Communication of the rotor chamber with the venturi passage reduces pressure in the rotor chamber to increase efficiency of the wind forces pushing on the rotor blades.
