    "device_name": "Over-Unity Generator",
    "goal": "Generate heat and electrical power in excess of the supplied electrical input (over-unity energy production).",
    "problem_addressed": "Provide a source of abundant clean energy that exceeds the energy required to operate the device, reducing dependence on conventional fuels.",
    "concept_summary": "A fluid (water mixed with a small amount of heavy water) is forced through a small orifice in a dielectric plate while being vibrated piezo-electrically. Cavitation bubbles collapse, causing dielectric breakdown and emission of electrons that create a high-density charge region. The device is claimed to produce excess heat and electricity, possibly via low-energy nuclear fusion (proton-boron or deuterium-deuterium reactions).",
