Patent ID: 7498685

Claim:
An electrical generator; wherein said generator is located in a body of water having a top surface, a water level and a bottom; wherein said generator is operable to generate electrical power in response to a change in said water level; and wherein said generator comprises: a buoyant pylon located in said body of water; a flexible attachment to anchor said buoyant pylon to said bottom of said body of water; a float carried by said body of water; two generator components; and a holder to hold said two generator components in a desired relationship with respect to each other; wherein said two generator components comprise an electrical coil and a magnet having magnetic fields; wherein a first one of said two generator components is attached to said buoyant pylon; wherein a second one of said two generator components is attached to said float; wherein said change in said water level causes relative motion between said float and said buoyant pylon, which in turn causes relative motion between said coil and said magnet and its said magnetic fields; and wherein said relative motion between said coil and said magnetic fields of said magnet causes electrical power to be generated by said coil.
