Santi, G G

The invention concerns a thermo-electric power station, supplied by a geothermal heat source, involving the use of at least two fluids. The first fluid (Water) makes it possible to transfer the geothermal energy from the subsoil to the power station. The fluid is pumped into the subsoil through a downcast shaft and returns, after being heated to a pre-establish temperature, via an outlet shaft. The second fluid is carbon dioxide, which, through direct contact with the first fluid, absorbs the latter's thermal energy and transforms it into mechanical energy via successive machines. A possible third fluid (Ammonia) produces, in an absorption refrigerator plant, the refrigeration necessary for lowering the temperature and, therefore, the pressure of the second fluid when it leaves the last machine, thus making possible the preestablished optimal pressure stage.
