ABSTRACT:
A wave energy power generating process and apparatus is presented which takes advantage of the changing hydrodynamic pressure of ocean waves. The present invention comprises a fluid (preferably a gas) filled constant pressure reservoir positioned on land adjacent the ocean, i.e., the beach, which is connected by a hose or conduit to a submerged wave machine. The submerged wave machine consists of a water filled outer housing and a fluid filled inner flexible bladder. The housing includes at least one opening through a wall thereof communicating with the ocean. The opening includes at least one turbine therein which is connected to an electrical generator. When a wave crest flows above the wave machine, the water pressure over the housing and inner reservoir increases thereby collapsing the bladder. The collapse of the bladder will decrease the volume thereof and provide increased volume for ocean water. As a result, water will flow into the outer housing through the housing opening and gas will flow into the constant pressure reservoir. This incoming water into the housing will flow through the turbine thereby generating electrical power. During a wave trough, the process is reversed whereby hydrostatic pressure on the housing and bladder decrease, thereby increasing the volume of the bladder, forcing water back out of the housing via the opening and through the turbine, thereby generating electricity.
