    "problem_addressed": "Dependence on fossil fuels, high energy costs, and environmental pollution associated with conventional energy generation.",
    "concept_summary": "A reactor chamber receives hydrogen, chlorine, and oxygen. When exposed to ultraviolet light (solar or artificial), the gases undergo an explosive exothermic reaction that creates a high-temperature plasma of ionized hydrochloric gas. The reaction releases kinetic energy that can be harvested directly by turbines or modified internal-combustion engines, while the resulting hydrochloric acid is recycled back into hydrogen and chlorine. The system claims to produce several times more kinetic energy than conventional hydrogen-oxygen combustion and many times more than gasoline.",
