Geothermal energy

The volume of the Earth is approximately 1085 mlrd.kub.km and all of it, except for a thin layer of the crust, has a very high temperature.
If we take into account the heat capacity of rocks and earth, it becomes clear that geothermal heat is certainly the largest source of energy, which currently has chelovek.Prichem is energy in its pure form, as it already exists as heat, and thus to obtain it required to burn fuel, or to create reactors.
In some areas, nature gives geothermal energy to the surface as steam or hot water, boiling and passing in pairs at the output of poverhnost.Prirodny pairs can be used directly for production elektroenergii.Imeyutsya also areas where geothermal water from springs and wells will be able to heat homes and Greenhouses (island state in the north Atlantic, Iceland, and our Kamchatka and the Kuriles)
However, in general, especially given the magnitude of deep geothermal power, geothermal energy in the world is extremely limited.
For the production of electricity using geothermal steam from the steam is separated solid particles by passing it through a separator and then send it to the turbine.
“The cost of fuel” such power is determined by the capital costs of productive wells and vapor collection system and is relatively nevysokoy.Stoimost of the plant at the same time is also low, since the latter does not have a furnace, boiler plant and chimney truby.V such a convenient form of a natural geothermal energy is ekonimicheski lucrative source of electrical energii.K Unfortunately, on the rare earth surface yields a natural steam or superheated (ie, a temperature much higher 100oS) water, boiling with the formation of a sufficient count of steam.
