NEW HYBRID POWER CYCLE FOR 100% CLEAN, AND CONTINUOUS (24x7) HAZARD-FREE LOW-COST POWER GENERATION AND TRANSPORTATION WITHOUT ANY FUEL AND USING ONLY AMBIENT THERMAL ENERGY

We disclose for the first time principles of a new single hybrid technology comprising a power cycle and a refrigeration cycle in a partial form, using in closed cycles a fixed amounts of the same working-fluid, the vapor part of which in the partial refrigeration cycle undergoes a polytropic compression with the rejected heat removed by the compressed liquid (of the working fluid) in the partial power cycle before both are combined together at the same pressure, prior to entering an ambient heat exchanger where they absorb ambient heat (normally from air flow) and undergo turbo expansion (when the desired temperature is reached) and thus to generate 100% clean electrical and mechanical power with specific power density (60 to 90 kJ/kg·N2 depending on P1,P2 and T1 in the single hybrid mode), using only ambient thermal energy (of air or water) and thus with no gas or emission exhausting to the atmosphere, without using any type of fuel, any solar panel or wind turbine and without using any water to cool any part of the equipment (unlike current fossil power plants) and hence at negligible power generating cost, with possibilities of varying the operating parameters within some ranges around the optimum parameters based on the detailed theory provided in the specification in full compliance of the laws of thermodynamics.

We disclose for the first time an astounding thermodynamic power cycle breakthrough, where a heat engine does not reject any heat portion from the heat input (from the heat source) to the surroundings unlike that in all conventional engines, but the said heat portion is reabsorbed by the engine itself to ensure nearly 100% efficiency of the engine (excluding the small efficiency loss due to frictions of the compressors and the turbo-expanders), this is being possible because the exhaust vapor from the turbo-expansion in a cryogenic heat engine comes out at temperatures well below any ambient temperature, hence it cannot be condensed by the surroundings as it is done in a conventional close cycle steam engine.

A novel technology for the first time to enable a power plant to also do the functions of a refrigeration plant, when the ambient heat exchanger of a hybrid cryogenic heat engine or a binary-hybrid cryogenic heat engine running at temperatures well below any ambient temperature replaces the evaporator in a refrigeration system and thereby the novel technology providing both refrigeration and air conditioning at a domestic and industrial capacity along with power generation, using only ambient heat which is abundant and costs zero dollar and without using any water and refrigerant.
