A Stirling engine includes: a housing for storing a heating medium in an internal space, a rotor eccentrically disposed in the housing and having a plurality of vane slots, a plurality of vanes inserted into the vane slots, a heater for heating the heating medium in the housing, a radiator for cooling the heating medium in the housing, and an output shaft coupled to the rotor so as to output power to the outside. In the Stirling engine, heat absorption portion-side vanes and heat radiation portion-side vanes are installed to the single rotor in the housing, a heat absorption portion and a heat radiation portion are formed in a single enclosed space in the housing, and the heating medium continuously undergoes isothermal expansion and isothermal compression under a constant volume, thereby generating power.

A system of captive oxygen fuel reactor to efficiently generate electricity from hydrocarbon fuel utilizes a flow of oxygen and a flow of hydrogen from an electrolysis unit and a flow of carbon monoxide in order to complete a fuel oxidizer reaction within a heat exchanger unit. The fuel oxidizer reaction emits a flow of steam and a flow of carbon dioxide from the heat exchanger unit re-direct them through a steam rotary piston motor unit, a carbon dioxide rotary piston motor unit, a steam carousel motor unit, a carbon dioxide carousel motor unit, and a duel drum motor unit to generate electrical current. The exhaust gases within the system are properly discharged and stored within respective storage containers for the use of the system or other possible requirements.

An alternative heat source for an internal combustion engine with an elongated compartment with first and second ends, a directed energy device capable of sending a pulse of photonic energy to a focal point within the first end of the compartment, an intake allowing for the entry of a gas into the the elongated compartment, an exhaust allowing for the exit of the gas from the elongated compartment, and a piston capable of moving within the elongated compartment between the first and second ends. The pulse of photonic energy at the focal point heats the gas and causes a corresponding expansion of the gas in the elongated compartment, driving the piston toward the second end of the elongated compartment, where the piston movement can be translated into motive force. The same principle can work with a rotary chamber, or a dual chambered linear system.
