1. A wind energy conversion system comprising:
A magnus rotor comprising,
a. a cylinder with endplates, said endplates traversed by a shaft about which said cylinder may be rotated,b. a motor operatively connected to said shaft,c. a shield extended over said endplates and substantially half a radial surface of said cylinder,d. an aerodynamic seal circuit enveloping a volume of a vacuum between said shield and said cylinder and extended over a surface of said shield so a vacuum is not lost, ande. aerodynamic seals about said shaft and located on said shield so a vacuum within an interior of said cylinder is not lost, so when said cylinder is made to rotate aerodynamic drag on said cylinder is reduced. |
