Abstract: By optimizing the degree to which water is accelerated through a venturi device, the amount of power that an energy device extracts from the ocean is maximized. Prior venturi-based wave energy devices have proven to be inefficient because of the relatively small amount of power that they generate relative to their size and cost. By optimizing the venturi effect created within the submerged venturi components of such devices, the speed of the water moving through the narrowest portions of such a devices is maximized with respect to the wave environments in which they operate, and a maximal amount of energy is extracted from the ocean. This optimization of a wave energy device's power is sufficient to render such devices cost effective. The method of extracting energy from the accelerated flow of water moving through such venturi devices is not limited, and many alternatives exist, each with its own potential benefits.
