Apparatus for harnessing wave energy comprises a buoyant support structure with various pumps to be operated by the wave action or the reaction from the wave action. One type of pump is actuated by a disc that depends to a depth below the apparatus, and that is hollow and air-filled so as to have a buoyancy close to zero, and that responds to the wave action by actuating a piston within an upright cylinder. Vertical flaps, some of which depend downwardly and others of which extend upwardly, respond to the horizontal wave action to actuate further pumps. A third form of utilization of the wave energy is by pendulums mounted for horizontal swinging movement about vertical axes, whose inertia upon swinging movement of the apparatus, actuates further pumps. The wave energy can be transmitted to shore either as a fluid (air or water) pumped to shore by the pumps, or as electrical energy through an electrical cable, from a generator on the apparatus. In either event, the cable or conduit extends down along the anchor chain, and then to shore.
