Abstract:
1. A method of capturing wind energy using a cross-flow wind turbine comprising: providing an airfoil stator that has at least one surface that has a portion that is curved; generating a low pressure area on a leading face of a rotor blade by accelerating the flow of air across said curved surface of said airfoil stator that is positioned to form a predetermined gap between said rotor blade and said air foil stator during a power stroke of said rotor blade; using a blocking stator to substantially block wind from impeding movement of said rotor blade during a return cycle of said rotor blade and directing said substantially blocked wind to a trailing face of said rotor during said power stroke of said rotor blade so as to create a pressure differential between said leading face and said rotor blade and said trailing face of said rotor blade during said power stroke that creates a force that rotates said rotor blade.
