Steam or hot water deposits exist in relatively shallow depths within the earth's crust and can be used directly or by boreholes; the state of engineering allows the conversion into electric power or for a domestic and agricultural utilization. The maintenance of water pressure in a geothermal deposit requires the water injection : it is intended to exploit the heat and not the water. There are two principal types of geothermal deposits : the deposit of high enthalpy, the deposit of low enthalpy.  2, record 4, English, - geothermal%20deposit

Bladeless turbine... An assembly of plain metallic discs is mounted on a shaft, with narrow spaces between the discs. Geothermal fluid-hot water and/or steam-is admitted to the spaces between the discs at the periphery, and is directed to follow an inward spiral path towards a central exhaust port. The driving force is derived from frictional boundary layer drag between the fluid(s) and the disc surfaces. Such a machine would be very cheap to construct and to maintain : the discs could easily be dismantled, cleaned of chemical deposits and reassembled.  1, record 12, English, - bladeless%20turbine
