  • Wave powered desalination apparatus with turbine-driven pressurization
    Patent number: 5186822
    Abstract: A desalination apparatus including pressure responsive desalination means, a storage tank and conduit means connecting such storage tank to a pump mounted in a caisson defining a resonant chamber having an opening in one side thereof for receiving the incoming ocean waves. The caisson is configured in accordance with the natural frequency of the incoming waves and amplify such waves to drive a float coupled with the pump. Actuation of such pump pressurizes the storage tank to drive brine through the desalination means for separating therefrom potable water. The apparatus includes a turbine generator arranged to facilitate the pressurizing of the brine.
