Abstract
A float apparatus for harnessing the kinetic energy of waves. The float apparatus includes a float having a central vertical tunnel. An elongated housing is disposed within the tunnel, the housing has a closed top and an open bottom. A wire coil is disposed within the housing. A bar magnet is received within the housing and the wire coil, wherein the movement of the bar magnet relative to the wire coil within the housing results in generation of current in the wire coils. A ballast that submerges in water is suspended from the float body by multiple elastic cords. A shaft extends between the bar magnet and the ballast. The movement of the float body relative to the ballast by waves causes the magnet to move relative to the wire coils generating electricity.

A float apparatus for harnessing kinetic energy of waves, the float apparatus comprises:
- a float body, the float body has a central tunnel that extends vertically, the central tunnel has at least an opening at a bottom thereof, the float body is configured to remain afloat in water;
- an elongate housing disposed within the central tunnel, the elongate housing has a closed top and an open bottom;
- a wire coil disposed within the elongate housing,
- a bar magnet received within the elongate housing and the wire coil, wherein the bar magnet is configured to freely reciprocate within elongate housing, wherein movement of the bar magnet relative to the wire coil results in generation of current within the wire coil;
- a shaft having a proximal end and a distal end, the proximal end is coupled to the bar magnet, and the shaft extends from the bottom opening of the elongate housing;
- and
- a ballast, configured to be submerged in water, the distal end of the shaft is coupled to the ballast, the ballast is suspended from the float body by a plurality of elastic cords, wherein the ballast comprises a hollow body, the hollow body has a plurality of holes in a top thereof, wherein water fills into the hollow body through the plurality of holes.
A method for generating electricity from kinetic energy of waves, the method comprises:
- providing a float apparatus for harnessing kinetic energy of waves, the float apparatus comprises:

- a wire coil disposed within the elongate housing,
- a bar magnet received within the elongate housing and the wire coil, wherein the bar magnet is configured to reciprocate up and down with in the elongate housing, wherein movement of the bar magnet relative to the wire coil results in generation of current within the wire coil,
- a shaft having a proximal end and a distal end, the proximal end is coupled to the bar magnet, and the shaft extends from the bottom opening of the elongate housing, and
- a ballast configured to be submerged in water, the distal end of the shaft is configured to be couple to the ballast, the ballast is configured to be suspended from the float body by a plurality of elastic cords, wherein the ballast comprises a hollow body, the hollow body has a plurality of holes in a top thereof, wherein water fills into the hollow body through the plurality of holes;
- coupling the distal end of the shaft with the ballast;
- fastening the plurality of elastic cords between the float body and the ballast;
- and
- suspending the ballast in water, wherein the float body remains afloat in water.
