    "concept_summary": "A sealed generator uses an electrolyte containing dissolved zinc hydroxide and a pair of electrodes: an aluminum electrode that is consumed, and a composite electrode made of a non-ferrous conductive tube with an internal magnet whose outer surface is coated with magnetic nano-particles (nickel, iron, tungsten, cobalt or alloys). The nano-particle coating forms a second electrode that contacts the first. Chemical reactions between the aluminum, zinc hydroxide, and the nano-particles generate hydrogen gas without any external electrical input.",
