First Claim
Patent Images
1. An electrical system, comprising:
- a magnet constrained to move relative to a support structure, a ferrofluid disposed between said magnet and support structure to provide a low friction interface, a conductive coil disposed with respect to said magnet so that relative movement between said magnet and said coil generates an electrical signal in said coil, a pair of end magnets on opposite sides of, and opposing polarity to, said magnet to limit said magnet'"'"'s movement, and an operating system coupled to be provided with electrical energy by said electrical signal.

Abstract
An electrical generator includes a magnet constrained to move relative to a conductor by a support structure, with a ferrofluid bearing providing an ultra low friction interface between the magnet and support structure. The assembly has a critical angle of displacement from a horizontal static position of less than 1 degree, and preferably less than 10 minutes. An electrical signal is generated in the conductor by the moving magnetic field.
