NOVELTY - The method involves preparing a thermal mass (2100) and lowering the thermal mass to a heat absorption zone (2200). The thermal mass is raised (2400) to a heat transfer zone. Heat is transferred out of the thermal mass. The thermal mass is prepared by attaching the thermal mass to a suspension cable. The thermal mass is transferred (2500) to a thermal reservoir. The mass is provided with a chamber for containing thermal fluid such as water and molten salt that comprises potassium calcium nitrate, potassium nitrate and sodium fluoride. Transfer fluid is passed through a heat exchanger.    USE - Method for transferring geothermal heat i.e. geothermal energy, from thermal mass (claimed) within earth, to generate electricity and to drive an industrial process i.e. pyrolysis, in a production facility i.e. concentrated solar power (CSP) facility.    ADVANTAGE - The method enables transferring geothermal heat from thermal mass within earth without causing seismic damage or groundwater contamination, and utilizing substance with large volumetric energy density to absorb heat inside Earth from depths where temperature is greater than 100 C. The method enables lowering the thermal mass to the heat absorption zone and raising the thermal mass to the heat transfer zone so as to achieve proper lubrication, thus reducing energy losses due to friction and reducing drag encountered when the thermal mass is raised and lowered in a well shaft. The method enables allowing thermal mass to move and down on different sides of a single well shaft, thus reducing operation costs.    DETAILED DESCRIPTION - The transfer fluid is water and glycol-based fluid. INDEPENDENT CLAIMS are also included for the following:    (1) a thermal mass    (2) a method for extracting geothermal energy from Earth    (3) a method for generating electricity.
