Claim:
1. A wave energy harvester for generating electricity from transverse waves in a body of water, said wave energy harvester comprising a buoy that comprises a float and at least one cantilevered member attached to the float and radiating outwardly away from a longitudinal axis of said float in a position located externally of said float for exposure of said cantilevered member to surrounding water under placement of the buoy in said body of water, the at least one cantilevered member having piezoelectric material thereon arranged to generated electrical power under vibration of said at least one cantilevered member, wherein the float has an elongated axial dimension measured along the longitudinal axis between upper and lower ends of the float, the upper end of the float defining an upper end of the buoy and the buoy having a center of mass located nearer to said lower end of the float than to said upper end of the float, and the at least one cantilevered member is spaced a distance from said upper end of the float along the longitudinal axis thereof in order to reside in a submerged position below a surface of the body of water.
