    "inventor_name": "C. Earl Ammann",
    "publication_year": 1956,
    "device_name": "Activator Transformer / Atmospheric Generator",
    "goal": "Harvest ambient atmospheric electricity to provide unlimited power for lighting, propulsion and other uses.",
    "problem_addressed": "Dependence on wired power supplies and limited access to electricity.",
    "concept_summary": "A compact cylindrical device containing steel wires, iron, brass spheres and assorted minerals is claimed to draw ambient electric currents from the atmosphere, condense the charge and convert it into usable electrical power that can drive an automobile and light buildings.",
    "detailed_description": "The device is described as a roughly fist-sized cylindrical unit with two small brass spheres protruding from the top. Inside are steel wires and minerals arranged to capture the Earth's natural electric currents. An auxiliary \"Activator Transformer\" (size of two fists) placed within 10 m of the main coils is said to amplify the effect. Demonstrations reported in 1921 showed the apparatus attached to an old electric automobile, which allegedly ran without batteries, climbed hills and traveled through city traffic. The inventor claimed the system could also power buildings, battleships and steam turbines, and would work anywhere except underwater.",
