The present invention relates to the utilization of wave energy and its conversion into operating motion of an electrical energy generating system. The system for generation of electrical energy through the conversion of aquatic wave motion includes floating bodies and a constant rotation mechanism, which converts the two-way linear motion of an inflexible transmission shaft or a flexible transmission shafts into one-way rotation of an output shaft of the constant rotation mechanism. This mechanism allows utilization of wave energy in two directions caused by the rise and fall of waves. The output shaft of the constant rotation mechanism is coupled to a force multiplier that is further coupled to a generator which generates electrical energy. Constant rotation mechanism can be driven by inflexible transmission shaft pivotally coupled to the floating bodies at one end, and the other end to an input gear of the constant rotation mechanism. Depending on the height of the wave and the wavelength, various constructions of floating bodies are used. Certain floating bodies are designed for the waves of a smaller amplitude and smaller wavelength, while other floating bodies are designed for bigger amplitude and bigger wavelength.

A device to stabilize, reduce, or control the wave or wind-induced heave (vertical), surge (lateral), or pitching (rolling) motion of a floating or semi-submerged buoyant base, raft, barge, buoy or other buoyant body such as the buoyant base of a wave energy converter or a floating wind turbine base. The device concurrently allows the floating base to self-orient or weathervane to substantially maintains its orientation with respect to the direction of oncoming waves, winds, or wind gusts. The device also facilitates maintaining the submerged depth or vertical orientation of the buoyant base relative to the still water line to compensate for tidal depth changes. The device utilizes a second substantially submerged buoyant body having a center of buoyancy and at least one tensioned seabed connection located substantially below and forward or up-sea or up-wind of the center of buoyancy of the buoyant base. A structural member, which can optionally also be buoyant or integral with the base or second submerged body, connects the submerged buoyant body with the floating base.

This invention relates to method and apparatus for extracting energy from water waves to generate electric power. The wave energy converter uses sea wave oscillations, from a land-based position. It understood a land-based power take off apparatus (3) that is oscillated by waves conveyed to it by canal or tunnel. The canal has a funnel shaped intake (1) at the coastline, a wave control gate (9) positioned near the intake and a power take off apparatus (3) positioned inland across the canal with a float (8) that works pumping cylinders (7) that pump hydraulic fluid to turn an impulse turbine (5) coupled to an electricity generator to generate electricity. The canal depth is predetermined to float the float, of the power take off apparatus (3), at all tide levels.
