Abstract:
A reciprocating electric generator for use in an oscillating fluid comprising:a magnetic core having a magnetic center pole and radially configured outer poles to form an elongated annular bore extending thereinto and capped on both ends, said magnetic core being adapted to be submerged in an oscillating fluid; a plurality of permanent magnets mounted in said magnetic core along the outside diameter of said annular bore; a generator coil formed on a bobbin and slidably mounted in said annular bore; damping plates rigidly attached to the upper and lower ends of said generator coil at a minimum of three equally spaced angular locations and extending out from said generator coil for resisting the movement of generator coil to applied forces on the coil, thereby maintaining the generator coil in a stable position; said magnetic core having at least three linear spaces in the outside diameter of said annular bore to allow said damping plates to extend out from the said generator coil; vertical structural members connecting said upper and lower damping plates to form a rigid structure; buoy member floating on the surface of an oscillating fluid; and a rigid structure rigidly attached to the underside of said buoy member to hold said magnetic core and said generator coil at a predetermined fixed distance beneath said buoy member; whereby said magnetic core moves responsive to movement of said buoy on an oscillating fluid and said generator coil remains in a steady position with respect to the moving magnetic core to thereby produce electric power responsive to the movement of a buoy when positioning said buoy to float on an oscillating fluid.
