    "inventor_name": "Roy J. Meyers",
    "publication_year": 1913,
    "device_name": "Absorber",
    "goal": "Generate usable electricity from the atmosphere for lighting and power without moving parts or conventional fuel.",
    "problem_addressed": "Dependence on conventional energy sources and the need for a low-cost, continuous power supply.",
    "concept_summary": "The Absorber is a tower-mounted assembly of magnetized steel plates (disks) that allegedly attract ambient atmospheric electric charge. The collected charge is fed through a transformer core (iron core wrapped with copper wire) to produce a direct-current output that can power lights, engines, or other loads. The device claims to operate continuously day and night and to be scalable to city-wide power generation.",
