    "goal": "Provide a self-running power source capable of lighting a 300 W load without external fuel.",
    "problem_addressed": "Lack of portable, reliable power in post-WWII conditions and the desire for a free-energy source.",
    "concept_summary": "The Lockridge Device is a modified automotive DC generator that combines a motor, a generator, a flywheel, a capacitor, and a three-winding inductor. It is claimed to run autonomously, delivering about 300 W to a bank of light bulbs by extracting excess energy from an undefined \"vacuum\" or by reducing back-EMF in the motor.",

        "If the machine works ... it must be getting its excess energy from somewhere since capacitors coils commutators light bulb and wire are poor candidates for this energy source.",
