This thermal energy technology uses the heat generated from underground power transmission cables to drive steam turbines or other similar technologies to produce electricity and steam. Solvent/fluid is pumped under pressure with a temperature differential between the exit point from the "heat exchange station" to the entry point of the proceeding station where the temperature is near or at the critical point. At this point, heat is extracted form the solvent to produce steam to drive a steam turbine which in turn drives a generator to produce electricity. Exhaust steam is used to provide space heating and hot water for industrial plant processing. Also, the hot solvent (water) is cooled and mixed with the condensate (steam) in a cooling tower or combined with cold water (300 C) to be pumped into the encasement around the cables to create the low temperature zone and the process is repeated at specific intervals along the entire length of the transmission cable system. Depending on the required energy load, the location of the heat exchange station is a function of distance travelled, flow rate and pressure of the solvent flowing over the power cables within the encasement acting as insulation. Not withstanding, the claims implied in this technology includes the generation of electricity or steam from an underground transmission power cable at any voltage or temperature. The lattice or cross-over configure of the encased cable is designed to optimized temperature and pressure by converging the cross flow at the points of heat extraction within the closed loop. Spent steam will travel from a condenser to a cooling tower and back into the flow direction away from intersection for both arms in the loop.
