World ocean power resources. "Salty" energy.

Salty water of oceans and the seas conceals in itself the huge not mastered reserves of energy which can be effectively transformed to other forms of energy in areas with the big gradients of salinity what are a mouth of the largest rivers of the world, such as Amazon, Parana, Congo, etc. the Osmotic pressure arising at mixture of fresh river waters with salty, is proportional to a difference in concentrations of salts in these waters. On the average this pressure compounds 24 atm., and at a confluence of the river Jordan of the Dead Sea 500 atm. As a source of osmotic energy it is supposed to use also the salt domes concluded in a strata of an ocean bottom. Calculations have shown, that at use of the energy received at dissolution of salt of an average on oil resources of a salt dome, it is possible to receive not less energy, than at use of oil containing in it.

Operations on transformation of "salty" energy to the electrical are at a stage of projects and pilot plants. Among offered variants hydroosmotic devices with semipermeable membranes are of interest. In them there is a solvent suction through a membrane in solution. As solvents and solutions are used fresh water - a seawater or a seawater - a brine. Last receive at dissolution of depositions of a salt dome.

The scheme of operation of hydroosmotic power station

In the hydroosmotic chamber the brine from a salt dome blends with a seawater. From here water driving through the semipermeable membrane under pressure arrives on the turbine bridged to the electrogenerator.

The scheme of operation of submarine hydroosmotic station

The submarine hydroosmotic hydroelectric power station takes places on depth more than 100 m. Fresh water moves to the water-wheel on the pipeline. After the turbine it is pumped out in the sea by osmotic pompes in the form of blocks of semipermeable membranes the residual of river water with impurities and dissolved salts leave the flushing pompe.
