Abstract: A geothermal heat- and water supply plant comprises a geothermal well to remove brine which communicates with a separator which, in turn, communicates in the steam phase with a jet pump and a high pressure stage of an injector, and in the fluid phase--with the cooled side of a heat exchanger which communicates with the jet pump. Water is drawn from the injector outlet to water and heat supply systems, and once used therein, the water is fed to one inlet of the heat pump whose one outlet communicates with the injector high pressure stage. The other outlet of the heat pump communicates with the jet pump outlet, and the other outlet--with the well for pumping the brine.

Abstract: A liquid-metal magnetohydrodynamic converter comprising such hydraulically interconnected components as a heat source, a two-phase nozzle, a separator, a liquid diffuser, a liquid metal cooler, a magnetohydrodynamic generator and a means for heating and delivering liquid metal supplied from the cooler, all of said components being arranged successively so as to form a loop. A steam diffuser and a condenser are interconnected and hydraulically coupled to the separator and the means for heating and delivering liquid metal supplied from the cooler, respectively.

Abstract: A liquid-metal magnetohydrodynamic converter comprising such hydraulically interconnected components as a heat source a two-phase nozzle, a separator, a magnetohydrodynamic generator, a liquid diffuser, and a heat-regenerating means, said components being arranged successively so as to form a loop. The two-phase nozzle is provided with steam-bleeding units located in different sections over its length and having the outlets thereof coupled to steam inlets of the heat-regenerating means. A steam diffuser and a condenser are hydraulically interconnected and coupled to the separator and the steam inlet of the heat-regenerating means, respectively.

Abstract: An apparatus for the realization of a rock-exploitation method based on thermodynamic cycles utilizing an in-situ energy source including a well with a casing sunk at least as far down as a producing horizon, a string of exploitation pipes having at least one opening at the fluid outlet, and means for varying the heat content of the heat-carrying agent in one of the zones of the thermodynamic cycle of interaction with stratal fluid.
