Abstract
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.
Claims3
A fluid energy conversion system comprising:
- a. at least one magnus rotor means,
- b. a long rod means serving as a hub around which said magnus rotor means may be disposed, said rod means suspended on both ends at the tops of a divided pole means,
- c. an energy transmission means operatively connected to said magnus rotor means, and
- d. an electric generator means operatively connected to said transmission means,
- said rod means long enough so fluid turbulence around said magnus rotor means will be minimised and so as said magnus rotor means is operated then electrical energy is produced.
