Methods, systems, and apparatus for generating energy from a process-contained series of thermobaric reactions and/or explosion cycles are provided. The Xplogen™ energy generating system includes several embodiments for stimulating the heat and pressure release episodes, which are directed by the process system toward the task of dissociating a target substance being subjected to the hyper-stimulated pulse of energy. The target substance is thermolyzed by the pulse energy episode and the resulting dissociated gases are either quenched and captured or they are consumed in a direct thermal conversion process and are thus translated into steam pressure, and/or torque, thrust, motive force, and/or super-heat impulses. The methods and systems of the present invention include a comprehensive arrangement of process configurations and components as well as a means of operation.
