Systems, apparatus and methods for generating power from fluid motion, su ch as wind are provided. The apparatus is a wing-shaped airfoil with cup-sha ped indentations that allow the airfoil to harness wind energy throughout a wide range of wind speeds and from different wind directions. The indentatio ns harness wind energy at low wind speeds while the wing-shape generates a l ifting force at high wind speeds to harness wind energy. The system comprise s one or more of the devices configured in a hollow, generally cylindrical, shape and connected to a ring frame. The system rotates about an axis runnin g through the center of the ring frame. The rotational motion of the system generates electrical power via a generator. The method is a method for gener ating electrical power from the rotational motion of the system.
