    "problem_addressed": "Provide cheap, abundant, low-carbon energy and reduce dependence on fossil fuels.",
    "concept_summary": "The Energy Catalyzer (E-Cat) is claimed to be a cold-fusion reactor that fuses nickel and hydrogen at temperatures below 1000 K, producing copper as a by-product and releasing large amounts of heat. The device is powered by a modest electrical input (~=400 W) and allegedly outputs many kilowatts of thermal power.",
