    "device_name": "Etheric Wave Accumulator",
    "goal": "To collect electrical energy from the atmosphere (ether) and provide usable electric power without conventional generators.",
    "problem_addressed": "Dependence on conventional power generation and the desire for a free, ambient source of electricity.",
    "concept_summary": "Perrigo claimed to have built a device that harvests ambient electromagnetic radiation from the atmosphere (the so-called ether) using a specially arranged antenna of nails and fine wire, stores the collected charge in a pair of accumulator plates with protruding knobs and coils, and then steps the voltage up with a transformer to supply usable electricity. Demonstrations were reported of lighting houses, powering a car, and operating a handheld unit.",
    "detailed_description": "The invention consists of three main parts: (1) an antenna array made from roofing nails partially driven into a board, each nail wrapped with fine wire to form a small electromagnet; (2) two accumulator plates each bearing a 10 x 10 array of protruding knobs (material unspecified, possibly metal, lead, galena, wood, or a composite) with matching holes in an insulating sheet; in each hole a coil is wrapped around a bundle of wires, and the plates are sandwiched together with the insulator between them, creating a measurable voltage between points AA and BB; (3) a complex transformer attached to the plates that further intensifies the voltage. The claimed operation is that the antenna collects ambient \"etheric wave\" energy, the coil-plate assembly stores and steps up the voltage, and the transformer delivers a high-voltage, low-current output that can light bulbs, run a house, or power a vehicle.",
