Ocean thermal energy conversion primer

This is referred to as OTECfor Ocean Thermal Energy Conversion. Several techniques have been proposed to use this ocean thermal resource; however, at present it appears that only the closed cycle (CC-OTEC) and the open cycle (OC-OTEC) schemes have a solid foundation of theoretical as well as experimental work.

Ocean Energy

Ocean energy is classified as tidal energy, wave energy and ocean thermal energy. Potential energy resources associated with major ocean currents, such as the East Australia Current or the Leeuwin Current, are not considered here. Tidal energy. Tides result from the gravitational attraction of the Earth-Moon-Sun system acting on the Earth''s oceans.

Marine energy

Marine energy or marine power (also sometimes referred to as ocean energy, ocean power, or marine and hydrokinetic energy) refers to the energy carried by ocean waves, tides, salinity, and ocean temperature differences.The movement of water in the world''s oceans creates a vast store of kinetic energy, or energy in motion.Some of this energy can be harnessed to generate
