Abstract: Engine systems and methods for performing a new chemical/thermodynamic cycle, termed a Chemo/thermodynamic Closed Combined (CCC) cycle, are proposed herein. The CCC cycle is composed of an Endothermic Chemo/thermodynamic Open cycle (En-C-O) and an Exothermic Chemo/thermodynamic Open cycle (Ex-C-O), which together complete the larger CCC cycle. CCC cycles may operate as a Combined Heat and Power (CHP) cycle. Since the En-C-O and the Ex-C-O cycles are able to operate independently of one another, they can be distanced from one another in time and/or space. To complete the larger CCC cycle, the En-C-O and Ex-C-O chemical working fluids are stored and/or transported between one another. An Exothermic Reactor Exhaust Compressor (EREC), for permitting otherwise-waste CCC heat to convert said chemical working fluids from liquid/frozen pressurized states into pressurized vapors and/or gases, is also proposed herein. Finally, various En-C-O and Ex-C-O cycles are proposed herein.

Abstract: The present invention proposes methods and apparatus for improving the technology disclosed in U.S. Pat. No. 3,225,538, U.S. Pat. No. 3,067,594, and U.S. Pat. No. 3,871,179, wherein are detailed techniques for creating a unique thermochemical cycle, termed the Bland/Ewing Cycle (B/E Cycle) after the co-inventors, involving “molecular expansion” and “molecular compression”. The advantage of the B/E Cycle is best exemplified in FIG. 3 and FIG. 4 of U.S. Pat. No. 3,225,538, where P/V and T/S charts indicate the potential for increased “power density”. This power density is a result of the reduced compression work following exothermic conversion of a single mole of gas relative to the increased expansion work following endothermic conversion of multiple moles of gas. The present invention improves power density and/or overall heat engine thermal efficiency by capturing otherwise-waste heat in the exhaust of a B/E Cycle heat engine.

Abstract: For efficiently exchanging heat between two streams of fluid at approximately equal pressure while simultaneously reducing the internal volume and general overall mass of the heat exchange means per quantity of heat exchanged over time, a means termed a Synchronized Thermal Regenerator Exchange Pump (STREP) is proposed.

Abstract: The present invention proposes a thermochemical battery cycle, termed a Benzene Battery cycle, for efficiently storing electric and/or thermal energy for later and/or distant use. The methods and apparatus herein proposed utilize reversible endothermic fluid and exothermic fluid thermochemical means for efficiently storing H2 in a liquid state at STP. The present invention is generally based on the technology disclosed in U.S. Pat. Nos. 3,225,538, 3,067,594, and 3,871,179, wherein techniques are described for creating a unique thermochemical cycle, termed the Bland/Ewing Cycle (B/E Cycle) after the co-inventors, involving “molecular expansion” and “molecular compression”. The present invention is also based on US Patent Application #18-0954634 which proposes optimizing endothermic and exothermic “segments” for the creation of either Combined Heat and Power (CHP) or Combined Cycle (CC) applications.
