NOVELTY - The universal heat exchanger comprises a closed loop thermally insulated line comprising a first heat exchanger coil, a second heat exchanger coil and a water pump inserted along the closed loop line. The water pump comprises a series of in-line pumps periodically inserted along the closed loop line. Each of the in-line pumps comprise an electromotor comprising a spiral blade within a hollow central shaft of the rotor creating a force to move fluid through the closed loop line, where the in-line pumps are inserted along the closed loop line in a downhill route and operated as generators.    USE - The universal heat exchanger is useful in a self contained, in-ground geothermal generator for producing electricity from geothermal sources such as lava and flare stacks, where the electricity is useful: for homes and businesses; and for production of hydrogen, which is used as a clean source of energy in auto industries and to recharge electric car batteries.    ADVANTAGE - The universal portable heat exchanger is capable of harnessing heat from the geothermal sources thus continuously and inexpensively producing the electricity.    DETAILED DESCRIPTION - The universal heat exchanger comprises a closed loop thermally insulated line comprising a first heat exchanger coil, a second heat exchanger coil and a water pump inserted along the closed loop line. The water pump comprises a series of in-line pumps periodically inserted along the closed loop line. Each of the in-line pumps comprise an electromotor comprising a spiral blade within a hollow central shaft of the rotor creating a force to move fluid through the closed loop line, where the in-line pumps are inserted along the closed loop line in a downhill route and operated as generators to supplement power to the electromotor of in-line pumps inserted along the closed loop line in an uphill or horizontal route. The second heat exchanger coil is coupled to a binary power unit comprising a second closed loop system with a working fluid having a boiling temperature lower than the boiling temperature of water, where the binary power unit generates electricity in response to the exchange of heat from the first heat exchanger at the source of heat. The universal heat exchanger further comprises: self-contained heat exchangers coupled to the binary power unit to form a binary power plant; a distiller/evaporator; a desalination building; and a load carrying and distributing system of the first heat exchange coil comprising a derrick with a pulley system, repetitive thermally insulated tubes, repetitive sling cable segments, periodic reduction cable segments and a repetitive cable and tube connector assembly platforms. The first heat exchanger coil is lowered into a damaged nuclear reactor, and the second heat exchanger is placed into a nearby cold environment to cool the reactor and surrounding area with the closed loop system. The first heat exchanger coil is positioned at top of flare stacks, and second heat exchanger is placed into the binary power unit on the ground where electricity is produced. The first heat exchanger coil is lowered into a warm mine, and the second heat exchanger coil is placed into a colder environment to cool the mine with the closed loop system. The first heat exchanger coil is placed near a lava flow, and the second heat exchanger coil is coupled into the binary geothermal power plant. The second closed loop system is engaged with a third set of closed loop system consisting of the first heat exchanger coupled into a condenser of the binary power unit, and second heat exchanger placed into nearby colder environment for cooling of the condenser. The first heat exchanger coil is placed at source of heat, and the second heat exchanger coil is coupled into distiller for heating the distiller. The distiller is filled with salty water and used steam for operating a turbine and generator for production of electricity. The remaining salty water is transported through a piping system into the desalination building and into containers for heating and evaporation. The containers with salty water are heated with the piping system from a first closed loop system and the condenser. The desalination building is a closed structure with a greenhouse effect. The desalination building comprises: the containers with salty water and its delivery system; a heating system positioned under the containers; the condenser positioned on upper portion of the building with its cooling system; a collection of fresh water and its distribution out of the building; and collection and distribution of collected salt. The repetitive cable segments consist of a sling cable ending with standard latched sling hooks. The periodic reduction cable segments consist of a sling cable, an oblong master link connecting two legs ending with standard latched sling hooks to connect with two cables on upper segment through cable and tube connector platforms providing efficient load distribution and overall weight reduction of the apparatus. The cable and tube connector assembly platforms consist of: a platform on which is permanently fastened tube and socket assembly for quick connect and disconnect of tubes; and a multiple steel cable loops assembly consisting of two sets of eyelets with thimbles formed at each end of the fastening block protruding on upper and lower portion of the connector platform. INDEPENDENT CLAIMS are included for:    (1) a method of using a universal heat exchanger; and    (2) a method of using a self-contained geo-thermal generator.
