Abstract: A wave energy harvester (100A) includes an element (120A) that converts forward and/or backward of water in a wave (102A. B. C) passing the harveste r (100A) into upward and/or downward movement to thereby increase the vertical amplitude of the harvester (100A) relative to the sea floor (104A. B. C). In most preferred aspects, the element (120A) is a hydrofoil that is coupled to the harvester (100A). Further preferred aspects include those in which part of, or the entire harvester (100A) has a neutral buoyancy, and where energy is extracted from the downwards movement of the neutrally buoyant part (100A) after a wave has lifted that part (110A).
