Resumen de: US2024151204A1
An apparatus that floats at the surface of a body of water over which waves pass, causing a nominally vertical axis of the apparatus to tilt away from an axis normal to the resting surface of the body of water. Tilting allows a fluid to flow through a channel that in an un-tilted apparatus would require the gravitational potential energy of the fluid to increase (i.e., to flow uphill), but, because of the tilt allows the fluid to flow through the channel in a downhill direction. Successive wave-driven tilts of the apparatus incrementally raise water to a head from which a portion of its gravitational potential energy can be converted to electrical power by causing the water to return to a lower level by flowing through a water turbine, or through some other apparatus that performs a useful function when supplied with a flow of high-pressure water.

An electrical generator with a wave energy accumulator where the generator uses a centrifugal method to convert sea wave energy into electrical energy. The generator has the appearance of a floating buoy and contains a power generation system. The buoy is connected to a frame that rises above the sea surface and is designed to match the characteristics of a variety of sea conditions. The structure can also adjust the height of the buoy pivot point thereby maintaining the balance of the rocking force or the movement of the buoy. Centrifugal rotation and the force and revolution generated by the centrifugal rotation is accumulated by a torsion spring system that is prevented from uncoiling while accumulating rounds and is released to rotate when a specified accumulated rounds has be reached. The accumulated energy from the rotation of the centrifuge is then used to drive an electric generator to produce electricity.
