It is known that the energy reserves in the oceans are enormous. This thermal energy corresponding to overheating of surface water compared to bottom at 20 degrees, is about 1026 G. A kinetic energy of ocean currents estimated at 1018 G. However, the time being, people can only use a very small proportion of these energies, and the cost of large investments slowly paying off. Until recent times the use of ocean energy seemed unprofitable.

    But now that the ever-growing energy prices force us to seek new ways to extract energy, ocean energy is the most promising direction of future energy development. In recent years a number of countries are seriously interested in the features of the ocean. In some countries okeanoenerhetyka already well developed.

   Most common is the production of energy from energy tides. In 1967, in Delta r.Rans, France, is tidal power station (SES) capacity of 240 MW. Here tides reach a height of 13 m In 1968, Soviet engineer Bernstein developed a convenient way to tow SES in the right place. In the same year he built an experimental SES in acid Bay, near Murmansk. Now based SES capacity of 6000 MW in the Barents Sea.

    Another possibility was rapidly growing giant ocean algae kelp that easy pereroblyuyutsya of methane. In addition, the number of carbon monoxide released by combustion of gas received, you can easily return to the ocean, if equatorial regions dissolve in water pure iron. Iron causes rapid growth of plankton and the number increases by several tens of times, and plankton in water using dissolved carbon dioxide Generally, the ocean is concentrated most of the released carbon dioxide, is carried out studies to reduce the temperature of the planet by dissolution in water of pure iron . Scientists say that 10,000 tons of iron in the ocean rozchynenh can reduce the temperature in atmosveri planet by 0.5 ° C!. A large number of plankton, absorbing the energy settles on the ocean floor and, over time new forms of dependence of fuel resources. In general, for power supply 1 person quite a hectare plantation kelp.

    Also, much attention is drawn "okeanotermichniy enerhokonversiyi" (libraries), that is receiving energy from the difference of temperature of water at different depths.

   Another possibility is the use of ocean currents: flow velocity Holfstrim off the coast of Florida reaches 5 miles / hour. The idea of ​​establishing this giant underwater turbines are quite attractive.

   Already, many lighthouses that are installed on the water off the coast of Japan and the United States, powered only by ocean waves. A power projects that use ocean waves for energy production, but these stations should have gigantic dimensions, and therefore such projects is not taken seriously.

   Oceans also has inexhaustible reserves of the cleaner fuel like hydrogen. Maybe maybutnomu humanity and learn to produce electricity only "clean" means, but is unlikely to aircraft or vehicle on the electric motor will have good characteristics. Another thing - hydrogen. Its fuel quality is several times better than gasoline or diesel fuel. But there are some problems with the storage of hydrogen - it is too explosive. Back in 1996 the corporation "H'yundayi" has developed a revolutionary technology of storing hydrogen in the crystal lattice of metals. This development has allowed a first hidromobil, which was considered sufficiently safe for consumer and came to mass production. Technical performance of the car much better, and the only emissions - water vapor.

    In general, the oceans are the most promising and most beneficial energy source of the future. It seems to be a giant accumulator absorbs solar radiation, wind energy and the energy that appears as a result of changes in gravitational fields of Earth and Moon.
