    "publication_year": 1990,
    "device_name": "Hyde Generator",
    "goal": "Convert high-voltage/low-current electrostatic energy into low-voltage/high-current DC power, allegedly achieving over-unity (free-energy) performance.",
    "problem_addressed": "Provide electrical power derived from static electric fields with minimal mechanical input, reducing reliance on conventional energy sources.",
    "concept_summary": "The Hyde Generator uses externally charged electrode plates to create opposing electrostatic fields. Pairs of stator discs with conductive segments are positioned opposite the electrodes. Rotating conductive rotor discs partially shield the stator segments, periodically varying charge linkages between electrodes and stators. This modulation induces a high voltage between the stators, which is stepped down by a diode-capacitor output circuit to deliver low-voltage, high-current DC power to a load. The inventor claims the device outputs more power than the mechanical input, implying over-unity operation.",
