This invention describes a miniaturized hybrid diesel-electric engine formed by a closed-loop system powered by plasma-aided combustion of JP-8 fuel (or other hydrocarbon fuels) working in tandem with a vapor cycle utilizing miniaturized expanders and condensers. The output of this engine is electric power and mechanical work. Water, or organic fluids, heated by the combustion product developed inside a special burner, undergoes an explosive, quasi-supersonic conversion to steam. This steam drives a high-speed turbine connected together with a gas turbine outputting shaft work. This work output is utilized to power internal subsystems, cool down the miniaturized condensers, and to produce torque and electric power. The dimensions of this miniaturized hybrid-engine are so compact that it can fit inside the battery compartment of most applications requiring high-density miniaturized power sources.
