Patent abstract
A wave energy converter utilizes a flotation module that rises and falls with the passage of waves, a submerged tube containing a constriction which multiplies the speed of the water passing therethrough, a turbine (or other hydrokinetic apparatus) positioned so as to extract energy from the accelerated flow of water within and/or through the tube, and a submerged gas- or liquid-filled chamber housing one or more energy conversion components (e.g. generators, transformers, rectifiers, inverters). By providing a chamber in proximity to the turbine, generators can be placed in closer proximity to the turbine that turns them, and the shared shaft can be shorter than if the generators were placed in the buoy adjacent to the surface.
