Power generated by a wind turbine is applied to drive reverse osmosis (RO) desalination. Rather than discharging the brine back into the ocean, it is concentrated and modified through industrial-scale processes to produce sodium hydroxide (NaOH). Direct air capture of CO.sub.2 occurs when liquid NaOH, created from the RO desalination brine, is conveyed to the rotor hub and emitted from the wind turbine blades to react with CO.sub.2 in the atmosphere. The power of an offshore wind turbine is used for the onboard production of fresh water to supply shoreside water needs, or water may be electrolyzed to produce hydrogen while adding the vital process of CO.sub.2 sequestration to the ocean.

Various embodiments of a submerged sailing vessel are disclosed. Such a submerged sailing vessel may comprise a submersible hull assembly, a keel coupled to and extending upwards from hull assembly towards a water surface, and a wind-catching assembly coupled to and extending upwards into the air from the keel for propelling the submerged sailing vessel. The hull assembly and keel are submerged below the water surface as the vessel is propelled by the wind-catching assembly above the water surface.

A motion damping system includes a tank compartmentalized to have a first compartment having a first opening, a second compartment having a second opening, and a third compartment disposed between the first and second compartments. The third compartment is in fluid communication with the first and second openings. A first piston is movably sealed within the first compartment and is in fluid communication with its first opening. A second piston is movably sealed within the second compartment and is in fluid communication with its second opening. A liquid fills the third compartment, a portion of the first compartment up to the first piston, and a portion of the second compartment up to the second piston. A coupling fixedly attached to the first and second pistons moves in correspondence with the first and second pistons. Motion damper(s) coupled to the coupling resist movements of the first and second pistons.
