Abstract: A proportional moving air power transmission and energy collection and control system includes a fixed vertical spindle, a vertical rotational hub and a plurality of wings being supported around the vertical hub in 360°. Each of the wings has a blunt leading end and a pointy trailing end and defining an outer surface and an inner surface. In a fully opened position, the trailing end of each wing is moved away from the vertical hub to a diameter of the wing assembly to drive the vertical hub to rotate. In a fully closed position, the wings are overlapped with each other end-to-end to form a hollow cylinder-like structure to furl, such that the diameter of the wing assembly is minimized for facing the wind at all direction.
