Abstract
A Savonius Rotor may use the flow of wind or the flow of water from undersea current or tidal movement. The Savonius Rotor is passively vented and has a base support ring, and a space frame support structure supported on the base support ring. The space frame has building block cube elements which facilitate the ease of on-site assembly and erection. The space frame support structure supports sails and louvered panel assemblies for each of the cube elements. The louvered panel assemblies close passively when facing into the wind or ocean flow and open passively when moving into the wind or ocean flow. A distributed gearbox including planetary power takeoff assemblies located on the perimeter of the base support ring is provided for transfer of the extracted wind or ocean flow through the planetary power takeoff assemblies at points arrayed about the perimeter of the base ring.
