Energy complex I is designed to produce primary energy from renewable energy and supply it to various customers to ensure hydrogen, are what eghosa the main fuel for diesel generators, generating electricity is the main product of the LME.

Energy complex I is equipped with the primary sources of electrical energy:

- wind power plant 3. The proposed design differs from prototype high efficiency. This is due to the new design of the rotor and a new method of converting kinetic energy into electrical energy, which allows to extend the range of the used wind speed of 0.2 m/s to 50 m/S.

The rotor of this turbine produces two halichondria blades resting on the top and bottom hoops with a diameter of 2 meters to the bottom Hoop is attached to the rim of the worm wheel which engages with the worm driving shaft of the generator, producing electric power;

- photovoltaic station 4, differs from the prototype high rate of conversion of light energy into electrical energy. This is due to the use of concentrates light and use photocells;

- hydroelectric installation 5, unlike the prototype converts the kinetic energy of sea of unrest (swell waves) into electrical energy. This is done using network float micro elements power station;

- thermoelemente battery 6 is installed in a tub of deservedness 10 (figure 2). It consists of a number of thermocouples (figure 2 - in which ISE in position "a").

thermocouple is installed on the bottom of the tub of deservedness 10. In the lower part it has a thermo stabilizer 22. It served him deep water with a constant temperature of + 4°C.

The upper part of thermocouple is a thermo stabilizer 26. Inside it is the heating element 27, which is connected by wires 25 to thermoelectric power generator 24. Between the upper and lower parts of thermocouple is provided by insulating gasket 23.

The upper part of thermocouple (thermo stabilizer) 26 is in the upper (hot) bath water. In addition, water is heated by thermoelectric power generator 24, which is on the border of thermal stabilizers.

Due to the temperature difference at the boundary of thermocouple, separating the two metals, for example iron and bismuth, is formed thermopower is proportional to the temperature difference between the upper and lower stabilizers. From thermogenerator is energized to heat the upper part of thermocouple.

Galvanostatically battery 7, consisting of galvanisation produces electrical energy by chemical oxidation reaction between the aluminum and the electrolyte is prepared from sea water.

Unlike the prototype for continuous operation haloaluminate battery 7 is provided with an automatic replacement aluminum electrodes as well as the window is of electrolyte and unloading of the formed slag (Al 3O3). Uploaded aluminium dioxide is sent to recovery. After restoring the obtained electrodes for the BBB that allows you to organize waste-free production of electricity.

Fuel and chemical elemental station 8, consists of vodorodovozdushnykh elements and is designed to convert the chemical energy of combining hydrogen and oxygen into electrical energy. For the occurrence of this reaction required the electrolyte and a platinum catalyst, and strict maintenance of thermal mode.

In the proposed device the supply of hydrogen is made from totalizer that produce hydrogen from hydrogen sulfide.

The battery pack 9 (BAB) is designed to provide continuous operation and energy complex, as well as to ensure the smooth operation of totalizer 13 generating hydrogen for the power block. As batteries are used, for example, condenser batteries with long life, or iron-Nickel batteries, low self-discharge.

To ensure collaboration of primary energy sources among consumers provides the power control and distribution of primary sources of renewable energy (not shown). It ensures the operation of pumps, compressors, heating devices, totalizer and other

B is OK fence deep water II is designed to be transported by sea water from a depth of over 100 m It consists of a mechanical screen filter 1 and an intake deepwater pipeline 2. Pipe length may vary depending on the location of the station in the waters. The upper end of the assembled intake deepwater pipeline is fixed in the lower part of the bath deservedness 10.

Water flow produced by a pump (not shown).

Complex processing of sea water (CPMV) III is designed to produce clean fuel, hydrogen, used diesel generators, which are the main sources of energy CMAS.

It contains a bath of deservedness 10 located therein thermopiles 6, the electrolytic bath 11, a bath evaporation of sea water 12, totalizer 13, installation, cleaning and drying of the hydrogen 14 and block liquefaction of oxygen 15.

Food processing sea water are hydrogen, oxygen, hydrogen sulfide, sulfur, sea salt and distilled water.

Hydrogen is used in a gaseous state to clean power TEN and diesel generators power unit. Part of the hydrogen is stored in a water tank of hydrogen 16.

Hydrogen on LMEs is produced from two sources:

from hydrogen sulfide by totalizer. This hydrogen is TEN for the generation of electric energy, providing work accessory unit;

the ay electrolysis of sea water. Features of hydrogen on the LME is used as the electrolyte is sea water. This is done by heating the electrolyte to t°=70...80°using perforated multilayer electrodes in conjunction with asbestos diaphragms prevent the formation of explosive mixtures of hydrogen and oxygen. As practice shows, the energy consumption under these conditions is 5.3...5.9 kW·h 1 m3of hydrogen.

During electrolysis the concentration of sea salt in the bath is continuously increasing. The resulting brine flows by gravity into the bath evaporation 12 where to get the sea salt by evaporation. Bath evaporation of sea water 12 is used to obtain the final product is sea salt, which is valuable medical and industrial raw materials, as well as distilled water needed for hydrogen purification.

Device for producing hydrogen by electrolysis of water from the bath provides that a dedicated hydrogen together with electrolyte (sea water) is fed into the separation column, cooled by water flowing through the coil.

In the separation column separates the hydrogen from the electrolyte. The latter flows back into the electrolyzer and the hydrogen enters the washer with distilled water, where it is cleaned from the remnants of the electrolyte. From probyvat the La direct hydrogen in the installation of adsorption of hydrogen 14 and then in the underwater tank of hydrogen 16.

The stabilization unit stations (BSS) VI is designed to provide reasonable parametric rolling LMEs in conditions of sea state up to 5-7 points inclusive. It is equipped with devices for measuring parameters of sea and actuators providing semistability LMEs when the sea is rough. Conditions wolnostojacy LMEs are achieved by creating a platform catamaran base type, the station relies on two pontoons, inside which are the power plant, ballast tanks, fuel and pumps. The geometric dimensions of the pontoons, the distance between them, the sediment, the volume of the ballast tanks and the position of the center of mass LMEs are determined based on the simultaneous execution conditions of buoyancy for a given payload, stability, seaworthiness, wolnostojacy and minimum pitching. One problem that always occurs when you create a catamaran base platforms are the problem of stiffness and strength of the connection between the pontoons. However, these connections can be made useful for the movement LMEs and wolnostojacy. To do this, at the level of the bottom of the pontoons rigidly interconnected wing profiles, defined bulge up and deployed at an angle of attack during the course of LMEs against the waves.

In addition, to increase wolnostojacy LMEs used underwater tank is odorata 16. When the sea is rough, the Executive mechanisms wolnostojacy 28 pumps the hydrogen gas in the outer container, mounted on the platform LMEs, turn the gas tank in a vertical position, upload it calculated for the rough seas of the number of ballast. Moreover, the outer surface of the tank body is a cone-shape in vertical position narrowing to the top at an angle of 10 -140°. This form allows you to exclude the change in stability IEC due to the fact that tapering up the body with vertical strokes decreases the moment of inertia of the instantaneous waterline when immersed in water, and the increase - in surfacing.

Works LMEs as follows. Energy complex I produces electrical energy from renewable energy sources in offline mode. Developed LMEs energy is used to get mostly clean fuel - hydrogen. Using the temperature difference between deep and surface water, galvanizaelectrocasters battery using the electrolyte of the sea water, and hydroelectric station that uses waves or energy undercurrents, dramatically increased the number of generated hydrogen is the main fuel of diesel engines, producing the main product - electricity in the major who's volumes. For uninterrupted supply of diesel generators in the station entered the underwater tank. The presence of the gas tank helps to ensure smooth flow of hydrogen in diesel generators and, therefore, the constancy of the parameters of the output current.

In addition to the generation of electric current on the LME, as by-products produced oxygen, crystalline sulfur and sea salt. Simultaneously, the station conducts reservedartist sea water in the Parking lot, and may perform the tasks of cleaning waters from contaminants.

Measuring devices of sea wave parameters the signals to the actuators, ensuring semistability CME at sea state than itself provide stabilization LMEs when the sea is rough.

The main advantages of LMEs before the prototype is:

the software itself stabilization LMEs when the sea is rough;

eco-friendly more electrical energy that can provide power supply to coastal and marine facilities;

ensuring sinergeticheskogo effect on multiple strengthening derived from renewable energy sources on the sea;

the receiving side useful products, such as oxygen, sea salt, etc.
