The present invention is directed at the thermodynamic property amplification of a given thermal supply, provided by hydrocarbon combustion or in the preferred application heat provided by low-grade geothermal energy from the earth, for a vapor power cycle. The present invention achieves the desired objectives by segregating the compressible supercritical energy stream from the heat exchanger (boiler) into hot and cool fractions using a vortex tube, where the hot temperature is elevated above the heat exchanger temperature; and adding back heat (enthalpy) to the cool stream increasing the cool temperature to that of the geothermal heat exchanger. The heat-exchanger (boiler) supercritical gaseous mass flow segregated by a counterflow vortex tube (or bank of vortex tubes) forms hot and cool fractions where the hot temperature is raised above the heat-exchanger supply temperature, and heat (enthalpy) is added to the cool stream thereby increasing the cool temperature to that of the heat exchanger supply temperature.
