    "concept_summary": "An electrolytic hydrogen generator (HHO generator) uses electricity (from the engine or an independent source) to split water (including seawater) into hydrogen and oxygen. The resulting gas mixture is injected into the engine intake, where it combines with the hydrocarbon fuel, improving combustion efficiency, reducing emissions, and purportedly doubling fuel economy.",
