NOVELTY - The system has a heat engine exhibiting a pause in a cycle of heat engine sufficient in time to induce rise in temperature, and resultant pressure rising at constant volume of gas in thermal compression and expansion cylinders (183) in an isochoric process due to combustion of the gas and fuel mixture in thermal combustion chambers (137, 139). Heat transfer volume is in thermal communication with the heat engine, and a drawing unit draws fluid into the heat transfer volume such that the heat is added to the fluid by unit of the exhaust gases form the engine in the isochoric process.    USE - Thermal compression and waste heat recovery system for converting potential energy in fuel to kinetic energy through a heat engine to produce electricity for residential application e.g. residential hot water heating application, residential baseboard heating application and residential radiant floor heating application, commercial application and business/other applications e.g. driving stationary systems application e.g. heat pumps, energy storage systems and industrial equipment application, and transportation applications e.g. hybrid passenger transportation vehicles application, locomotives transportation application and marine transportation applications.    ADVANTAGE - The system minimizes moving parts of the heat engine so as to create a robust and durable system that is efficient to manufacture. The system provides a hybrid system that combines a thermal compression and internal combustion engine and thermal compression waste heat recovery system to convert potential energy into kinetic energy in an efficient manner, thus maximizing overall system efficiency and reducing fuel consumption, fuel costs, and greenhouse gas emissions in an effective manner. The system allows expansion occurs adiabatically as the expander walls to be insulated so as to prevent thermal losses to the engine block and other mechanical structures, and allows full expansion, air containing residual heat and waste products from combustion to be exhausted as waste, and the cycle is repeated. The system allows for recovering waste heat from large heat sources and offering a self-sustaining completely free of green house gas emissions so as to convert percent of that available heat into work to generate electricity or to drive other applications in an high-efficiency manner.
