Abstract
A wind turbine having one or more magnets for reducing friction between the turbine support and a turbine rotor. The reduction of friction between the turbine rotor and the turbine support allows for an increase in energy production and scale of the wind turbines. The magnet configuration employs a ring of cylindrically-shaped magnets at the bottom and opposed by a corresponding number of generally rectangular-shaped magnets. Bearing magnets are also employed for axial stabilization.
Claims20
A wind turbine, comprising:
- a turbine rotor;
- a turbine support;
- a first magnet set located on a lower surface of said turbine rotor, magnets therein having a generally rectangular shape and disposed in a ring along said lower surface of said turbine rotor;
- and
- a second magnet set located on an upper surface of said turbine support, magnets therein having a generally cylindrical shape, each of said generally cylindrically-shaped magnets being disposed in a ring and substantially aligned below at least one of said rectangularly-shaped magnets in said first magnet set,
- whereby, in operation, said first magnet set on said turbine rotor and said second magnet set on said turbine support separate due to magnetic repulsion, wherein a space is created by the magnet sets in opposition allowing the rotor to rotate with reduced friction.

A method for generating electricity, comprising:
- lifting, through magnetic repulsion between opposing magnets, a vertical turbine rotor off of a turbine support, thereby reducing the friction between the vertical turbine rotor and the turbine support,
- wherein a first magnet set being located on a lower surface of said vertical turbine rotor, magnets therein having a generally rectangular shape and disposed in a ring along said lower surface of said vertical turbine rotor, and
- wherein a second magnet set being located on an upper surface of said turbine support, magnets therein having a generally cylindrical shape, each of said generally cylindrically-shaped magnets being disposed in a ring and substantially aligned below at least one of said generally rectangularly-shaped magnets in said first magnet set;
- rotating, after said lefting, the vertical turbine rotor relative to the turbine support using the wind, the rotation of said vertical turbine rotor generating energy;
- and
- converting the energy of the moving vertical turbine rotor into electric power.
