    Abstract: One embodiment of an improved thermal power cycle comprising a wet motive fluid, pump (21), evaporator (22), expander (23), and condenser (24). Using a wet motive fluid, it can: (i) operate efficiently over a lower range of heat source temperatures than the steam Rankine cycle, (ii) eliminate the need for superheating the fluid in evaporator (22), (iii) allow for complete expansion of the fluid in expander (23), and/or (iv) reduce back-pressure by the fluid on expander (23), thereby providing higher efficiency than the ORC (organic Rankine cycle), Eliminating the regenerator that is used by ORC systems results in a simpler, less costly system. Using direct-contact heat exchange in condenser (24) rather than the indirect-contact heat exchange used by ORC systems results in more efficient condensation of the fluid. Using a pump (21) rather than the power-hungry compressor used by ORC systems further reduces power losses and expenses.

    Abstract: A thermal utilization system is capable of producing power, storing energy via a chemical or and a hydropower-elevation means. It also capable of transport fluid as vapor over obstacles and terrains, as well as desalinate water. It may in some embodiments do all or some of these tasks simultaneously and with the same amount of energy. It may run with any source of energy including renewable energy sources such as solar energy, and wind. The system may use that energy to run a heat engine and, at the same time, stores that energy via chemical separation. When energy is needed, the system may withdraw the chemical substances and lets them interact to claim the energy back, and then use it to run a heat engine and desalinate water. Some parts of the system can be used for cooling and heating. The system may be configured to be an air conditioner unit or a refrigerator that has an internal back up energy storage.

    Abstract: A system for the generation of mechanical or electrical energy from heat energy, where increasing a height or pressure in a liquid chamber of the system containing a liquid increases an efficiency of the system up to a hundred percent or increases such efficiency until a critical temperature or pressure of the vapor (gas) is reached at the bottom of liquid chamber or in the boiler of the system depending upon the increment in height, pressure and the type of liquid used in the system. An increase in height of the system for such increased efficiency can be adjusted to a smaller height by maintaining a series of liquid and gas chambers where the vapor flows through the series of chambers or by adding pressure valves. The heat energy from high to low temperature sources can be convened to mechanical and electrical energy.

    Abstract: A system method of geothermal energy recovery includes injecting carbon dioxide into a geothermal reservoir through an injection well, extracting a working fluid including previously injected carbon dioxide and hydrocarbons entrained in a flow of the carbon dioxide within the reservoir from an extraction well, separating components of the heated working fluid based on chemical composition, selectively mixing the separated components according to the current conditions of the extracted working fluid to produce an output modified working fluid that having a chemical composition that is optimized for energy recovery efficiency, and expanding the modified working fluid to generate mechanical or electrical energy.

    Abstract: The invention discloses a method for converting thermal energy into mechanical energy, and/or for cooling, comprising the steps of at least partly evaporating a working fluid, expanding said evaporated working fluid, absorbing said expanded working fluid into a liquid absorption mixture, at least partly extracting the absorption mixture from the absorber, pressurizing said extracted absorption mixture, separating said pressurized absorption mixture into a working effluent and an absorption effluent, and feeding said working and absorption effluent to the evaporator and absorber respectively. In particular, during said separation, the absorption mixture is subjected to a pressure at or above the condensation pressure of the substantially pure working fluid, and/or to a temperature at or below the condensation temperature of the substantially pure working fluid. The invention further discloses a closed-cycle absorption system, preferably suitable for performing the method.

    Abstract: In a cryogenic combined cycle power plant electric power drives a cryogenic refrigerator to store energy by cooling air to a liquid state for storage within tanks, followed by subsequent release of the stored energy by first pressurizing the liquid air, then regasifying the liquid air and raising the temperature of the regasified air at least in part with heat exhausted from a combustion turbine, and then expanding the heated regasified air through a hot gas expander to generate power. The expanded regasified air exhausted from the expander may be used to cool and make denser the inlet air to the combustion turbine. The combustion turbine exhaust gases may be used to drive an organic Rankine bottoming cycle. An alternative source of heat such as thermal storage, for example, may be used in place of or in addition to the combustion turbine.
