Resumen de: US2025172118A1
Disclosed is an apparatus that floats at the surface of a body of water over which waves pass. Passing waves cause a nominally vertical axis of the apparatus to tilt away from an axis normal to the resting surface of the body of water. Tilting of sufficient magnitude and duration 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. Flowing water is trapped at a plurality of levels which in an un-tilted apparatus are higher than the respective levels from which the fluid has flowed. A subsequent tilt of the apparatus in a sufficiently different direction, and of a sufficient magnitude and duration, causes the trapped water to flow to new, yet higher levels. Successive wave-driven tilts of the apparatus incrementally raise water to a height and/or head from which a portion of its gravitational potential energy can be released, and/or converted to electrical power, by causing the water to return to a lower level by flowing through a water turbine thereby energizing an operationally connected generator, or through some other apparatus that performs a useful function when supplied with a flow of high-pressure water.

A method by which an environmental energy (e.g., wave energy) is harvested, converted into electrical power, and thereafter used to electrolyze seawater into hydrogen and chlorine gases. Those gases are recombined into hydrogen chloride from which is formed hydrochloric acid solution which is diluted and deposited at a depth sufficient to ensure its neutralization and sequestration for a significant period of time (e.g., for over a millennium). By removing chloride ions from a portion of the sea adjacent to its upper surface and depositing them into a portion of the sea more adjacent to its bottom, acidity is shifted from the surface to base of the sea, and the surface ocean is given a greater ability to absorb and buffer atmospheric carbon dioxide without a corresponding increase in acidity.

This invention introduces a kinetic energy recovery wind-wave integrated system for offshore wind power generation. The system consists of a semi-submersible platform equipped with a fan and an internal wave energy device. The device includes a shell housing a Power Take-Off (PTO) system, featuring a permanent magnet synchronous linear motor and an active controller. The motor's stator is fixed inside the shell, while its mover is connected to a counterweight block outside the stator, linked to the shell's top via a spring. Limiters are installed at both ends of the shell to restrict the counterweight block's movement. This system utilizes the wave energy device to absorb kinetic energy, which otherwise affects wind turbine stability, and converts it into usable electrical energy via the PTO system. This enhances the stability and safety of offshore wind turbine power generation.
