Abstract

An apparatus for capturing a portion of the wave energy on the surface of a body of water and converting the captured energy to a usable form of power incudes a large array of flotation devices, each connected to one of a plurality of energy conversion devices such as piston pumps. The conversion devices are all secured to a common frame structure which is supported by the buoyancy of the flotation devices. The apparatus floats with a draft which is a function of the average wave height in the area covered by the array. The lateral dimensions of the apparatus are greater than the expected wavelength to maintain a generally horizontal disposition. The apparatus may be moored at virtually any marine location, and the energy produced is transferred to storage facilities by a submerged conduit. The moorings may include winching means to submerge the apparatus during storms and high seas. A plurality of such apparatus may be disposed to form a breakwater to protect a harbor, beach, or the like.
