    摘要: A geothermal energy installation and system, in which the field of potable water is utilized by a secondary conduit system to route potable water from an inlet in the user's line coming from the potable water field but upstream of the user's meter, through the heat exchanger equipment of a user, and back to the field at a point upstream of the final treatment processing stage of the field. Thus, the thermal energy of the water of the field is utilized without adding the cost of the volume of potable water use by the user, and is re-processed if somehow contaminated in the secondary conduit systems; and although the secondary conduit system delivers water back to the field at a changed temperature, depending upon the heat exchanger effect, the relatively large volume of water of the potable water field assures that the returned water does not even substantially alter the temperature of the potable water field.

    摘要: The Hot-Weak-Rock process avoids the technical limitation of the Hot-Dry-Rock process that, from a given depth, the shear forces building up in the rock for releasing the heating area through hydro-frac cannot be overcome. The hot-weak-rock process shifts the creation of a heating zone into a region of the continental lithosphere where the shear forces of the hot rock drop abruptly as the superimposed pressure increases and already initiates Hydro-Frac to split a heating zone through the hydrostatic pressure of a hydraulic column of a suitably deep and lined bore-hole. All that is needed to split the lower, unlined section of the bore-hole is additional pressure in its water column, which presents no technical problem.
