TL;DR: In this paper, a tethered floating helix coupled to an electric generator is used to generate electric power in an offshore water electrolysis plant, where linear alternators are mounted for reciprocation on a column which extends through the air-sea interface.
Abstract: An offshore water electrolysis plant which produces pressurized gas by electrolysis of fresh water and wave power includes the combination of a wave-powered electric generator at the ocean surface, an electrolyzer and storage vessels located on the ocean bottom for providing gas under pressure, and a source of fresh water at the ocean surface forced down to the submerged electrolyzer through the use of a water-filled standpipe. In one embodiment, the electric power generating system includes a tethered floating helix coupled to an electric generator, in which the helix is automatically aligned with the wave propagation direction, while in another embodiment linear alternators are mounted for reciprocation on a column which extends through the air-sea interface, with each alternator provided with a donut-shaped float, such that electric power is generated as each float moves vertically up and down responsive to wave motion.

TL;DR: In this article, an apparatus for converting power from the wave motion of a body of water comprises a chamber with an opening for receiving waves and a float within the chamber is connected to a pump for converting the energy of the waves into useful energy.
Abstract: An apparatus for converting power from the wave motion of a body of water comprises a chamber with an opening for receiving waves. The chamber amplifies the amplitude of the waves. The wall of the chamber preferably has protuberance adjacent the opening for smoothing the flow of water through the opening. A float within the chamber is connected to a pump for converting the energy of the waves into useful energy.

TL;DR: In this article, uncertainties in determining the offshore wind and wave energies were considered to estimate the wind energy potentials in the southern Caspian Sea, and the results showed that uncertainty analysis results in almost 9% lower average wave power density and 7.3% less exploitable energy than conventional analysis.
