    "problem_addressed": "Low agricultural yields, heavy reliance on chemical pesticides and fertilizers, disease spread in crops and livestock (e.g., African swine fever).",
    "concept_summary": "High-voltage electric fields are generated by copper wires strung above greenhouse crops or animal pens. The electric field (up to 50 kV, micro-ampere currents) kills bacteria and viruses, reduces water surface tension on leaves, and accelerates ion transport within plants, thereby boosting photosynthesis and growth while suppressing disease.",

        "The technique has boosted vegetable output by 20 to 30 per cent. Pesticide use has decreased 70 to 100 per cent. And fertiliser consumption has dropped more than 20 per cent.",
        "The wires are capable of generating rapid, positive charges as high as 50,000 volts, or more than 400 times the standard residential voltage in the US.",
        "The electric current flowing through the wires is only a few millionths of an ampere by volume, a lower than a smartphone cable's workload. It does absolutely no harm to the plants or to humans standing nearby.",
        "One hectare of electrified greenhouse requires about 15 kilowatt-hours of electricity per day, which is about half the power usage of an average American family.",
        "The high-voltage discharges could break down chemicals such as ammonia ... reduce biological aerosol by 50 to 90 per cent, kill germs and generate negatively charged particles in the air that bind to air-polluting chemicals and make them harmless."
