A fluid energy conversion system using a Magnus Rotor to generate force and electrical power from passing fluid such as wind. A Magnus Rotor is mounted atop support structure which is far enough away from the surface of the Rotor to minimize fluid turbulence around the peripheral surfaces of the Rotor. The Rotor is mounted on a long horizontal shaft supported by a divided pole on either end. This divided pole is mounted on a pivot so the Magnus Rotor will be faced to the oncoming fluid by a weathervane. Minimizing fluid turbulence can result in greater power production.
