    "title": "PODMOD Over-unity power generator",
    "inventor_name": "Scott McKie",
    "publication_year": 1993,
    "device_name": "PODMOD",
    "goal": "Generate electrical power output that exceeds the input power (over-unity) to replace conventional power generation and provide abundant, cheap energy.",
    "problem_addressed": "Dependence on conventional energy sources, high-voltage transmission infrastructure, and the need for a perpetual-motion-type power source.",
    "concept_summary": "The PODMOD device uses two resonant tank circuits (each comprising a capacitor and an inductor) that alternately charge one another. By exploiting electromagnetic resonance and high-frequency switching, the system is claimed to amplify the input energy many thousands of times, producing net output power without fuel or moving parts.",
    "detailed_description": "The prototype is a roughly one-foot-square cardboard enclosure housing two LC tank circuits on circuit boards. One circuit is charged while the other delivers power; the roles are then swapped via rapid switching. The interaction of the capacitors and inductors creates a resonant condition that, according to the inventor, allows the system to output far more energy than is supplied. The design is intended to be scaled up into box-car-sized \"POD Mods\" that can run off a 12-V battery and deliver up to 10 MW of continuous power. No moving parts or fuel are used; the device relies solely on electrical input and resonance phenomena.",
