ABSTRACT:
A wave enhancer of this invention may be employed with a wave power collection system. This system converts the movement of ocean waves into useful energy. In order to convert the energy of the ocean waves into useful energy, the wave power collection system may have a float that floats on the surface of the ocean. Coupled to the float may be a mechanism for converting the movement of the float into another form of energy. This mechanism may be a hydraulic system that causes the up and down movement of the float to pressurize a hydraulic fluid. This pressurized hydraulic fluid can be used to power a prime mover, which in turn can drive a load, such as an electrical generator.
The wave enhancer of this invention increases the amplitude of a given wave. This increase in amplitude causes a corresponding increase in the amount of energy that can be extracted from a given wave. In a preferred embodiment, the wave enhancer includes a plate that is disposed on a cylinder of the wave power collection system. The plate is preferably disposed below the ocean surface, and the cylinder extends upward and is coupled to the float. Preferably, the wave enhancer is disposed in a predetermined angular relationship with the direction of motion of the waves. As the waves contact the plate a vertical lifting force is created. This lifting force causes the amplitude of the waves to be enhanced.
