ABSTRACT:
A device for deriving power from the energy of moving water waves includes a bag of flexible, impervious and inelastic material filled with a liquid to at least half but less than full capacity thereof and being adapted for submergence below the surface of a body of water parallel to the principle direction of movement of the waves. A passageway element having open opposite ends is in communication with the interior of the bag and forms together therewith a closed circuit flow as the liquid is channeled between opposite ends of the bag in a direction opposite the principle direction of movement of the waves. An electric power generator with turbine blades thereon is disposed between opposite ends of the passageway element. The liquid within the bag is subjected to an undulating motion between its ends in response to the movement of the waves in such direction as the weight of the waves creates corresponding currents of liquid within the bag, the currents of liquid thereby operating the turbine blades upon the movement of the liquid waves between the ends of the passageway element.
