Patent ID: 8552607

Claim:
An electric generator comprising: first and second stators, each stator including a plurality of magnets separated by a plurality of magnetizable materials, the magnets configured such that the direction of magnetization alternates between adjacent magnets whereby magnetic flux is concentrated in the magnetizable materials; a rotor positioned between the first and second stators and configured to rotate in a horizontal plane, the rotor having a plurality of coils in which current is induced during rotation from passing through magnetic fields generated by the stators; a first set of ferrofluid bearings positioned between the first stator and the rotor; a second set of ferrofluid bearings positioned between the rotor and the second stator; a third set of ferrofluid bearings positioned adjacent the periphery of the rotor and configured to center the rotor: and an electrical connector positioned substantially at the center of the rotor for making electrical contact with a receptacle holding a liquid metal positioned adjacent the electrical connector.
