    "publication_year": 1978,
    "device_name": "Moray Radiant Energy Receiver",
    "goal": "Capture ambient cosmic radiant energy and convert it into usable electrical power for lighting, heating and mechanical work.",
    "problem_addressed": "Dependence on conventional fuel and electricity sources; desire for a free, ubiquitous energy supply.",
    "concept_summary": "The Moray device consists of an antenna, a ground connection, and a solid-state \"Moray valve\" made from a soft white semi-conductive stone with silver wiring. When tuned with a magnet, the system couples to an unspecified high-frequency radiant energy that permeates space, rectifies it, and delivers high-voltage, high-power electrical output without drawing energy from internal batteries or the grid.",
    "detailed_description": "The apparatus is housed in a small wooden box containing a magnet, switch, and light receptacle. An external antenna (copper wire up to 200 ft long) is stretched high above the ground and connected to the device via insulated leads. A ground rod (water pipe) is driven into the earth. The user tunes the device by stroking a magnet across metal projections, which allegedly brings the internal circuitry into resonance with the ambient \"radiant energy\". Once tuned, the device produces voltages up to 250 kV and powers loads such as a 100-W incandescent lamp, a 655-W flat-iron heater, and a space heater, delivering up to 50 kW of power. Demonstrations were performed miles from power lines, and the output ceased when the antenna or ground was disconnected, requiring retuning.",

        "He was able to show that none of the energy came from within his device. Internally the device was electrically dead when it had not been connected and tuned to the antenna.",
        "The device produced up to 50,000 watts of power and worked for long periods of time.",
        "When the antenna lead-in wire was disconnected the light went out; reconnecting it caused the light to re-appear.",
        "Dr. Eyring found no fault with the demonstration and suggested that if the device operated miles away from power lines it could not be induction.",
        "The light was about 75 % as bright as a 100-watt globe connected to an ordinary house socket."
