Known patent "gas Turbine is a method of obtaining electricity and gas turbine power plant" (see the description of the patent RU No. 2125662 C1 IPC IS 41/32, F03B 13/00)providing for the production of electric power by the drive of the electric generator gas turbine, the compressor which serves the air temperature in the range from -10 to -70 of grads, and into the chamber of the interaction of injected water in the form of fine sprays with droplet size not greater than 0.2 mm

The disadvantage of this method primarily in the fact that he has very limited application, theoretically it is applicable on the Earth's surface only in areas with long-lasting effects of very low temperatures -10 to -70 of grads where problematic any economic activity, besides getting water aerosols with a size of 0.2 mm to perform technically very difficult, since the water will not make the phase transition, leading, apparently, to the ice chamber and the turbine, i.e. to stop the plant.

The known method for the production of hydrocarbon minerals - oil and gas, geological structures, located at the bottom of the seas. To do this, in stationary conditions produce specialized floating platform with drilling equipment, towing is in the sea, set in the estimated location and then perform the drilling and production.

Known technical solution "Floating platform and method of Assembly" (see description to the patent of Russian Federation №2137670 IPC V 35/44, publ. 20.09.99,, bul), which provides a way to build mobile coastal drilling rig is a floating platform with its subsequent towing and anchoring to the ground anchor links. The main disadvantage is that it does not solve the problem of land use for a long time, does not enter into the economic turnover, in this case, coastal areas, in addition, the platform has a complex structure and requires for operation a large number of staff.

On the surface of the Earth there are huge areas that are not suitable for commercial use, either because of geographical, climatic, hydrographic factors, or withdrawn from agricultural use as a result of human activity. Such parts of the surface of the Earth are:

- coastal area of the sea, subject to natural tides and low tides;

- the shoreline of the coast of the waves of the seas and lakes;

- the territory of radioactive contamination resulting from nuclear tests and accidents at nuclear facilities, major nuclear disasters;

- site burial of radioactive materials and radio is effective taken out of the ground;

- the territories contaminated by chemical, toxic and biological substances;

- areas contaminated by oil and oil products, as a result of accidents pipelines high pressure;

- the city of polygons, i.e. directly adjacent to the towns and settlements of urban dump of household waste;

- field irrigation and public treatment plants municipal sewer;

bogs industrial - former natural waters heavily polluted by industrial waste, petroleum products, household garbage;

- non-metalliferous excavation dumps;

- riverine area of rivers subject to prolonged inundation of flood waters;

- low-lying areas in the floodplain of the rivers;

- shallow waters (agricultural and forest lands), derived from economic turnover when they were flooded to create the expenditure of reservoirs for hydropower;

- natural bogs in developed areas;

- areas of economic activity in permafrost;

- circumpolar territories with a very short (1-1 .5 months) and cool summers;

mountainous and rocky areas.

Piles are made resistant to corrosion. The method of use of areas of the Earth's surface, not suitable for continuous commercial use, characterized in that at these sites construct the above-mentioned power generation unit, with the subsequent transfer of electrical energy from this area.

The construction of the electricity generating unit, its adjustment, the construction of transmission lines perform well-established technology small staff in a short period of time. The relatively simple design of the entire structure, good performance of power-generating unit: continuous operation for several weeks is set to automatic start and run without permanent staff, great technical resource (tens of years), high reliability, and fast payback - by power generation unit to enter into economic circulation areas of the Earth's surface, not suitable for any reason, or for household use. Another way, more simple, reliable, quick, efficient introduction in economic circulation of the above areas of the Earth's surface at the present time does not exist.

21 is a vertical profile of some portion of the Earth's surface in mountainous terrain.

JV the property applies to all of the above parts of the surface of the Earth. A typical example might be some remote territory on the riverbed, where diverse economic activities, constant electricity shortages. This area (see drawing) is exposed to annual long-term flood until the water level 1 long-term flooding of the territory. Under intensive lidocane flood waters can rise to the maximum water level rise 2.

At the end of the season the water goes below level 3 Land surface on 1-1,5 months. Thus, this area most of the year withdrawn from economic circulation and is not used. It is in this place being built electricity generating unit.

For this 4 piles embedded in soil 5. To increase service life in wet soils and acidic soils used piles, malopodvijnyi corrosion. The height of the piles 4 on level 3 of the Earth's surface exceeds the maximum level 2 rise of water. The upper part of the piles interconnected monolithic horizontal platform 6, is provided in accordance with the documentation, fixing and mounting assemblies.
