Abstract: A method and device are provided for generating energy from the motion of waves. Fluid is conveyed through stages in series, each stage having at least one unit, and each unit incrementally increasing the energy available. The fluid passes under the forces created by differential pressure within that unit and energy from a preceding stage is input into the succeeding stage in series. Preferably, each unit includes a first member and an associated second member, the first member being immersed in or floating on the surface of a body of water, the first member rising and falling with the rise and fall of wave motion, and the second member being anchored. Energy is created as the result of the relative movement between the first and second members as the fluid passes through a unit. The fluid may then be used to drive turbines and electric generators or other energy conversion devices.

Abstract: A method and device are provided for generating energy from the motion of waves. Fluid is conveyed through a series of fluid pressurization units, each unit incrementally increasing the pressure of the fluid as the fluid passes under the force of differential pressure within that unit. The pressurized fluid from a preceding unit is outlet from that unit and input into the succeeding unit in series. Each unit includes a first member and an associated second member, the first member being immersed in or floating on the surface of a body of water, the first member rising and falling with the rise and fall of wave motion, and the second member being submerged and anchored. The fluid is pressurized as the result of the relative movement between the first and second members as the fluid passes through a unit. The pressurized fluid may then be used to drive turbines and electric generators or other energy conversion devices.
