ABSTRACT:
A system for extracting useful energy from two masses of matter having polarized hot and cold temperatures operates in its primary embodiment with a looped circulation passageway having a condensing phase, an expansion phase and a working generally gaseous fluid that circulates through the loop. The expansion phase of the gas contains a relatively standing liquid through which the working gas, which is injected at the bottom, is allowed to buoy up to drive gas pressure turbines and principally a flotation turbines (floturbines).
The rest of the loop defines a return path which includes the condensing phase in which the expanded gas from the end of the last turbine is condensed to either a denser gas or to a liquid, and re-injected into the bottom of the condensation phase again, in a continuous cycle. Net energy output is achieved by heating the vertical expansion phase side of the loop with heat from the high temperature source to further expand the working gas and thereby increase the power that it delivers to the turbines, while using the cold temperature source to cool the working fluid in the condensing side, reducing the energy for reinjection.
