    "inventor_name": "Carlos F. Benitez",
    "publication_year": null,
    "device_name": "Self-Recharging Battery Supply (Benitez Battery Charger)",
    "goal": "Provide a self-charging battery system that yields net energy gain (overunity) and can power a motor/generator without external power.",
    "problem_addressed": "Batteries lose charge and require external charging; conventional chargers waste energy and cannot sustain continuous operation.",
    "concept_summary": "The Benitez system uses a network of condensers (capacitors), transformers, a rotary commutator, and switching circuitry to repeatedly transfer energy between two battery banks. By charging one set of batteries while discharging the other, and by employing high-frequency oscillations and resonant transformer coupling, the system claims to charge the batteries more than they are depleted, producing a net energy surplus.",
    "detailed_description": "Patented designs (GB191417811, GB191505591, GB191514311, GB121561) describe a primary condenser charged from a supply, a rotary commutator that alternately connects the condenser to transformer primaries and to earth, and secondary windings that charge additional condensers. The commutator rotates in steps, causing sequential discharge and recharge cycles that drive a motor/generator and a the excess energy through additional transformers. The circuit includes rectifiers, a spark-gap, and a \"Benitez-plug\" that couples high-impedance AC to earth. Demonstrations by Peter Lindemann (2018 ESTC) and RS Stafford used low-quality garden start batteries and reported that the batteries charged more than they discharged, especially when low-impedance deep-cycle batteries are used.",

        "Peter Lindemann demonstrated a system at the 2018 ESTC that ran on one battery bank, while charging another and it ran a motor/generator. The batteries charged up more than they discharged.",
        "RS Stafford repeated this demonstrated with a \"poor man's\" method that only required breakers from the hardware store. It also kept itself charged up and demonstrated more work than the net loss from the batteries.",
        "These are all overunity circuits, which have one thing in common, they all appear to have their roots in one man's work and that is the Self-Recharging Battery Supply of Carlos F. Benitez.",
        "The system being self-working, the switch 14 may be opened. When the commutator is rotated through a quarter of a revolution, the condenser 1 discharges through the primary 3, and the charge on the condenser 9 is increased."
