Abstract: A wave energy converter (WEC) system includes WEC devices which can function to produce useful energy (power) efficiently in response to heave motion and/or pitch motion and/or roll motion. Pitch responsive devices are deployed around the outer periphery of a container and one (or more) heave responsive device is located about the center of the container. The pitch responsive devices may be of the type defined as PDWECs which include two reaction masses which are primarily operable in response to pitching motion or they may be of the type which includes one reaction mass operable in response to pitch and/or heave motion.

Abstract: A wave energy converter (WEC) system includes a shell containing an internal oscillator comprised of a reaction mass suspended from the shell by an elastic spring in parallel with a constant force spring. The constant force spring provides a relatively constant force (Fc) to counterbalance the static weight of the reaction mass and reduce the extension “static” length of the elastic spring while the elastic spring exerts a force (Fes) on the reaction mass that is proportional to the displacement, x, of the elastic spring. A power take-off (PTO) device, located within the shell, coupled between the shell and the internal oscillator converts their relative motion into electrical energy.

Abstract: A wave energy converter (WEC) includes a float tending to move in phase with the waves, a spar tending to move out of phase with the float and power take off device (PTO) coupled between the float and spar for converting their relative motion into useful energy. The PTO includes a rack and pinion mechanism which drives a high-torque, multi-pole, permanent magnet generator (PMG) to produce electrical signals of relatively high frequency relative to the frequency of the waves and the basic motion of the rack and pinion mechanism. In accordance with one aspect of the invention, the rack and pinion mechanism may be located within the spar which may be hermetically sealed by a sealing mechanism which allows a thrust rod coupled between the float and spar to move up and down with little friction to ensure efficient operation. In addition, a braking arrangement is provided for inhibiting relative motion between the float and spar during extreme severe wave conditions. In this way, the pinion gears and generators need only be sized for the operational wave conditions.

Abstract: The stability and power conversion efficiency of a wave energy converter (WEC) which includes a float, a spar and a power taken device (PTO) connected between the spar and the float is increased by connecting a heave plate to the spar in a very secure manner and by carefully limiting the movement between the float and spar to one direction (i.e., up-down motion). Buoyancy chambers may be attached to the WEC to facilitate its transportation and deployment. The WEC may be formed in sections and assembled at, or close to, the point of deployment.

Abstract: A WEC system embodying the invention includes a column and shell, arranged to move relative to each other, and a lever-like apparatus having an input end and an output end and an intermediate point, between the two ends, the intermediate point being rotatably connected to the column. The input end is connected to the shell and moves at the same velocity and in the same direction as the shell. The output end moves in the opposite direction and at a rate which is a multiple of the shell velocity. The multiple being a function of the ratio of the length of the intermediate point to the output and input ends. In systems embodying the invention, one of two components (a PMA or an ICA) of a linear electric generator may be attached to the shell and the other of the two components may be attached to the output end of the lever-like apparatus to produce high relative velocity between the two components resulting in higher amplitude and higher frequency output voltages.

Abstract: Piezoelectric electrical generators comprise cantilevered beams of piezoelectric material, cross sections of the beams preferably being triangular and of increasing area from free end to fixed end. Arrays of spaced apart beams are disposed in overlapping, interdigitated relationships with arrays of cams, and the cam arrays are moved relative to the beam arrays for causing engagement and deflection of the beams by the cams for the generation of electrical energy. One system comprises a raft floating on the surface of an ocean. Cam arrays are suspended from the raft for interaction with vertically extending beam arrays mounted on the ocean floor beneath the raft. Relative vertical movements are caused by passing surface waves. In another system, beam arrays are suspended from an above surface structure, e.g., an oil drilling ocean platform, and the beam arrays extend towards and interact with cam arrays mounted on the upper surface of a floating raft.

Abstract: A system for converting the mechanical energy of ocean waves to electrical energy comprises a weighted member supported from a piezoelectric element for applying a preselected strain to the element. In one embodiment, the element is supported by a float floating on the surface of the water. In another embodiment, the element is supported above the surface of the water and the weighted member, of negative buoyancy, is immersed in the water. The system functions, in use, as an oscillating, weighted spring and, for tuning the system to cause it to enter into mechanical resonance in response to passing waves, means are provided for tuning the natural frequency of the oscillating system.
