    "device_name": "BAC Coil",
    "goal": "Improve water quality, reduce fuel and gas consumption, and harness ambient microwave energy for free-energy-like performance.",
    "problem_addressed": "Hard water scaling, high fuel consumption, inefficient combustion, and waste of ambient electromagnetic energy.",
    "concept_summary": "A bifilar-wound closed copper coil is wrapped around a fluid-carrying tube. The coil is claimed to magnetize the passing fluid, improve combustion of fuels, and act as an antenna that harvests ambient microwave radiation (8-15 GHz). The resulting magnetic field and induced voltage are said to lower fuel usage by up to 25-30 % and produce \"magnetized\" water with reduced hardness and contaminants.",
