Abstract: A wind powered energy generation apparatus, system and method. The apparatus may include a sail member having a windward surface and a leeward surface bounded by side edges and ends. The sail member may have a transverse width defined between the side edges and a longitudinal length defined between the ends. The apparatus may include a wind turbine including a bladed rotor configured to rotate about a central rotational axis. An end or a side edge of the sail member may be arranged proximate an outer periphery of the bladed rotor of the wind turbine. The longitudinal length or transverse width of the sail member may be inclined at an angle relative to a plane perpendicular to the central rotational axis. Wind flowing substantially parallel to the central rotational axis may form counter-rotating vortices about the side edges which vortices augment airflow across the bladed rotor of the wind turbine.
