    "inventor_name": "Ivan Stepanovich Filimonenko",
    "publication_year": 1995,
    "device_name": "Thermo-emission reactor",
    "goal": "Produce usable energy, generate motive force without reactive mass flow, and provide protection from nuclear radiation.",
    "problem_addressed": "Need for clean, low-radiation energy sources and propulsion methods that avoid nuclear waste and hazardous radiation.",
    "concept_summary": "Filimonenko's concept uses electrolysis of heavy water (deuterium-enriched water) in a palladium cathode. Deuterium is absorbed into the palladium lattice and undergoes a low-temperature (~=1000  deg C) fusion-like reaction that supposedly yields large thermal power with no neutron emission. The system is claimed to concentrate energy (syntropy), suppress induced radioactivity, and generate antigravity thrust by altering space-time curvature.",
    "detailed_description": "The patented \"Process and System for Thermo-emission\" (US 717239/38, 1962) describes a reactor where heavy water is electrolyzed; deuterium ions migrate into a hard palladium cathode where they fuse at ~1000  deg C. The reaction allegedly produces high thermal output (e.g., 12.5 kW per 0.7 m tube with a 9 g palladium cathode) while consuming only a small electric input, thus achieving over-unity. The inventor further claimed that the operating system emits a \"strange emission\" that lengthens half-life periods of radioactive isotopes, providing radiation shielding, and that the curvature of space-time is altered, yielding a syntropic (energy-concentrating) process and antigravity effects useful for propulsion.",

        "Small input electric power produce big thermo-power for this case and it is over-unity system.",
        "In 1989 and 1990 in Moscow area plant \"Lutch\" there were created two Filimonenko's reactors: the tubes of 0.7 m length and 0.041 m diameter. The palladium part is 9 g mass. Power is 12.5 kW for one reactor.",
