A system for converting the mechanical energy in the wave motion of a body of water into electrical energy. A frame is fixed with respect to the wave motion of the water. A flotation element is buoyantly supported by the water and constrained to follow only the vertical component of the wave motion.

A system for converting the mechanical energy in the wave motion of a body of water into electrical energy. A frame is fixed with respect to the wave motion of the water. A flotation element is buoyantly supported by the water and constrained to follow only the vertical component of the wave motion. The motion of the flotation element is transferred to an electrical generating device which includes a device for producing electromagnetic flux and electrical coils. The motion of the flotation element causes relative motion between the flux-producing device and the electrical coils thereby generating an electromotive force. A positioning subsystem is provided for moving the electrical generating device relative to the flotation element when the average depth of the body of water changes so as to maintain a symmetrical relative motion between the flux-producing device and the electrical coils.
