Resumen de: US2024376858A1
Provided is a wave energy power generation device, comprising a working platform, and a wave energy conversion mechanism, a wave energy storage mechanism and a wave energy power generation mechanism, which are arranged on the working platform. By means of the structures, such as a buoyancy tank, a lever, a gear set and a flywheel, the wave energy conversion mechanism converts wave energy, which is generated by wave fluctuation, into mechanical energy ensuring the continuous rotation of the flywheel. The wave energy storage mechanism, by means of compressed gas, collects and stores the wave energy.

The proposed invention is a direct drive converter of sea waves energy in electrical energy. It comprises a closed floating hull (1) and a weighted platform (2) within, equipped with coils and inductors respectively. The hull moves relatively to the platform upon facing the sea waves and electric current is induced in the coils. Hence, the sea waves energy is directly converted in electrical energy, avoiding energy losses on intermediate systems for the conversion. Also, the proposed invention incurs in more types of motion than other direct drive sea waves converters and is completely closed.

Resumen de: WO2024226442A1
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.
