 Wave powered buoy generator

Details

The wave powered buoy generator includes a hollow buoy which has inner and uter surfaces. The buoy is preferably spherical in shape. One or more windings are mounted to the buoy parallel to its surfaces with each winding having a pair of ends. A magnetized device which, is preferably a ball, is located within the buoy for rolling back and forth therein. A device is connected to the ends of the windings for rectifying current flow therefrom. With this arrangement the buoy can be moored in a body of water, and, when there is water motion, the flux lines of the magnetized roller device cut the one or more windings so as to cause electrical current flow to be provided through the rectifying device.

DETAILED DESCRIPTION What is claimed is: 1.
A buoy generator comprising: a hollow buoy having inner and outer surfaces; at least one winding mounted to the buoy parallel to its surfaces, the winding having a pair of ends; magnetized means freely disposed in all dimensions within the hollow buoy for unrestricted rolling on the inside surface of the hollow buoy whenever the hollow buoy has any rolling movement; and means connected to the winding ends for rectifying current flow therefrom, whereby, upon mooring the buoy in water, the flux lines of the magnetized roller means cut the winding when there is water motion and electrical current is provided by the winding through the rectifying means.
2.
A buoy generator as claimed in claim 1 including: the buoy being spherical; the magnetized means being a ball with at least one magnet located therein.
3.
A buoy generator as claimed in claim 2 including: the spherical buoy having a top and a bottom; a plurality of windings mounted to the buoy parallel to its surfaces, each winding having a pair of ends; said windings lying within vertical planes which include the vertical axis of the spherical buoy; and the windings crossing at the top of the spherical buoy and the ends of the windings being located at the bottom of the spherical buoy.
4.
A buoy generator as claimed in claim 3 including: a junction box mounted on the bottom exterior surface of the spherical buoy; the rectifying means being located in the junction box; and the ends of the windings being connected to the rectifying means.
5.
A buoy generator as claimed in claim 4 including: the spherical buoy being constructed of plastic and the windings being imbedded in the wall of the spherical buoy; the spherical buoy being split into hemispheres between its top and bottom; and each hemisphere having means for connecting the windings when the hemispheres are placed together to form the spherical buoy.
6.
A buoy generator as claimed in claim 4 including: the magnetized means being a ball with bar magnets aligned along the vertical axis and along each of a pair of orthogonal horizontal axes of the spherical buoy; and each axis having a pair of magnets aligned north to south and north to south in the same direction
