Abstract:
1. A system for harvesting energy from wave oscillation, the system comprising: an energy harvesting vessel comprising: at least one vessel hull for providing buoyancy to the vessel; a plurality of bobber devices retained in relation to at least one vessel hull wherein each bobber device comprises a buoyant float head and a means for retaining the float head for reciprocating movement in response to wave oscillation wherein the float head of each bobber device has a buoyant portion sufficient for causing the float head to rise with a rise in water level and a ballast portion sufficient for causing the float head to fall with a lowering in water level wherein the weight of the ballast portion of the float head is adjustable by a means for enabling an addition to or subtraction from a volume of ballast material retained inside the float head; and a means for converting the reciprocating movement of the buoyant float heads of the bobber devices to electrical energy; whereby energy can be harvested from an oncoming wave.
