Abstract

A long cylinder shaped beam is submerged in the ocean and suspended horizontally by multiple floats for converting ocean wave energy. The long length (at least the distance of the crest of two waves) and heavy weight of the beam, give the floats something stable to pull against. The weight of the beam pulling at the floats is transferred back and forth, as the ocean swells move over the beam, which activate machine components that may be installed in the beam, the floats or with rods connecting the floats to the beam. An individual float will not lift the beam except when the tide raises all the floats. The floats will pull and release the tension of the weight of the beam at randomly different times. The shape of the beam is straight. The ocean surface is continuously curving up and down and the beam will not bend to the shape of the ocean surface, but the floats will mimic the undulating or curvy shape of the ocean surface, and that motion actives the machine. The energy of the floats pulling against the elongated component is then turned into mechanical or hydraulic energy.
