TL;DR: In this paper, a vertical motion wave power generator with a flotation device, a vertical support structure fixed to the ocean bottom, and a single power shaft attached rotatably to the flotation devices is described.
Abstract: A vertical motion wave power generator having a flotation device, a vertical support structure fixed to the ocean bottom, and a single power shaft attached rotatably to the flotation device. By the use of a pair of one-way clutches the single power shaft converts the up and down motion of ocean waves into continuous unidirectional rotational force to drive an electric generator. The power shaft, transmission, and generator are all attached to the flotation device and move up and down in unison with the flotation device.

TL;DR: This paper presents techno–economic summaries of ocean wave, tidal and current, ocean thermal, and geothermal energy, including grid interface characteristics, suggesting these forms of energy represent a significant opportunity to complement diversified energy conversion portfolios.
Abstract: This paper presents techno–economic summaries of ocean wave, tidal and current, ocean thermal, and geothermal energy, including grid interface characteristics. These forms of energy represent a significant opportunity to complement diversified energy conversion portfolios. Ocean wave energy conversion relies on the capture of kinetic and potential energy in moving and elevated water in an ocean wave. Tidal and current technology converts the kinetic energy in moving water, much like a wind turbine. Ocean thermal converts the energy available in the temperature gradient of warm surface water and cold deep water. Last, geothermal conversion utilizes the hot rock and water deep within the Earth. The total global average wave resource is estimated at approximately 2000 GW, with approximately 300 GW in the United States. The total global tidal resource is estimated at approximately 1000 GW, with 50 GW in the United States. The marine current resource estimate for the Florida Current in the southeast United States is estimated at 5 GW. Ocean thermal has a global capacity estimate of 5000 GW. Last, the global conventional hydrothermal geothermal capacity estimate is approximately 200 GW, but with much more possible through enhanced geothermal systems. For cost, it was found that the long-term projected wave energy conversion cost is $0.10–0.15/kWh. The long-term projected tidal cost is found to be $0.025–0.25/kWh. Ocean thermal long-term cost is projected at $0.10–0.18/kWh. And last, geothermal, being more closely aligned with traditional thermal generation, is estimated at $0.03/kWh to $0.15/kWh.

TL;DR: In this article, the authors present a complete review of wave energy technologies describing, analyzing and fixing many of the concepts behind wave energy conversion and highlight the main wave-energy conversion projects around the world at different levels (demonstration stage, in production, and commercialized).
Abstract: The potential of electric power generation from marine renewable energy is enormous. Ocean waves are being recognized as a resource to be exploited for the sustainable generation of electrical power. The high load factors resulting from the fluid properties and the predictable resource characteristics make ocean waves particularly attractive for power generation and advantageous when compared to other renewable energies. Regarding this emerging and promising area of research, this paper presents a complete review of wave energy technologies describing, analyzing and fixing many of the concepts behind wave energy conversion. The proposed review will specifically highlights the main wave energy conversion projects around the world at different levels (demonstration stage, in production, and commercialized projects). In addition, a discussion will highlight challenges that wave energy converters need to overcome to become commercially competitive in the global energy market.
