Buoyancy and thermal differentials energy generator
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 s working generally gaseous circulating generative fluid or gas that circulates through the loop. The expansion phase of the generative fluid includes means to heat at least the generative fluid and a relatively standing liquid through which the generative fluid is allowed to buoy up and drive gas pressure turbines, in this case multi-wheeled flotation turbines composed of closable tube segments. The rest of the loop defines a return path that includes the condensing phase in which the expanded gas released by the turbine is condensed before being heated and re-exposed for expansion through said gas turbines again, in a continuous cycle. Net energy output is achieved by heating the generative fluid before it enters the turbine with heat imported from high temperature independent energy sources to create and/or increase the buoyancy power that it delivers to the turbine, while using low temperature sources to cool the generative fluid in the condensing phase.
