A means of reducing fluid density in front of Savonius blades by installing magnus rotors to accelerate onrushing fluid away from the blade itself. Several magnus rotors are mounted on either external side of the centerline of each blade, so as the Savonius rotor is revolved by the surrounding fluid and the magnus rotors are revolved on either side of the centerline in opposite directions, then fluid pressure is reduced and the Savonius rotor's speed is increased. Also, if the magnus rotor is formed from a sheathed flexible shaft and attached to an underlying contoured surface of a vehicle, such as a racing car or a helical Savonius rotor, fluid resistance to the forward motion of the vehicle is reduced.
