ABSTRACT:
A Savonius rotor assembly includes two blades. Each of the blades has an outer edge and an inner edge with the outer edges of the blades lying on a circle which define the diameter of the rotor. Each of the blades has a linear portion adjacent to the inner edge and a first curved portion which is substantially an arc of a circle tangent to the linear portion and tangent to the circle defining the rotor diameter. A second curved portion is substantially coincident to the circle defining the rotor diameter.
