    "publication_year": 1981,
    "device_name": "Jamison Energizer",
    "goal": "Provide continuous electrical power for vehicles and homes without the need for external recharging, by generating more electricity than the system consumes.",
    "problem_addressed": "Dependence on gasoline, oil, and periodic battery recharging for electric vehicles; limited range of conventional electric cars.",
    "concept_summary": "The Jamison Energizer is a double-wound rotor-stator motor that claims to produce excess electrical energy through capacitive coupling of bifilar windings. The generated electricity is stored in batteries, allowing a vehicle to operate indefinitely without external refueling or recharging.",
    "detailed_description": "The invention comprises a housing containing two compartments, each with a double-wound rotor nested inside a double-wound stator. Slip rings and brushes collect current from the rotor windings, while a bridge circuit transfers the energy to a battery and to an auxiliary motor that drives the rotors. The motor-driven energizer is said to generate more electrical power than it consumes, eliminating the need for battery recharging. A prototype was installed in a 1977 Ford Courier pickup, and a demonstration run was performed in the inventor's workshop.",

        "\"It produces more electricity than it uses and stores it up in batteries.\"",
        "\"Jamison's secret is a shiny metal cylinder a little more than a foot long and about 10 inches in diameter. He won't discuss what makes it work.\"",
        "\"He admits it has a couple of small bugs. He said a control switch that acts as an accelerator is giving him problems.\""
