    "goal": "Activate or suppress biological processes in plants to improve germination, control maturation, and devitalize pests.",
    "problem_addressed": "Low germination rates of seed stock, uncontrolled fruit maturation, and infestations of parasitic fungi and insects in industrial agriculture.",
    "concept_summary": "A method and apparatus that subjects plant material to high-frequency, high-voltage electric fields generated between resonant conductive plates. The material is moved on a belt (or allowed to fall) through the field, where voltage gradients and resonant conditions are tuned to activate or deactivate biological processes, thereby increasing germination, delaying maturation, and killing pests.",
    "detailed_description": "The invention uses an oscillating high-frequency circuit (15 MHz example) to drive voltage across a pair of large conductive plates spaced at a quarter-wavelength distance (e.g., 5 m for 15 MHz). Plant material on an endless belt passes between the plates, experiencing a voltage gradient from maximum at one end to zero at the other. By adjusting plate size, belt speed, and oscillator parameters, the treatment time and field strength are controlled. Resonant tuning ensures most of the supplied energy is transferred to the material with minimal waste. Variations include additional plate pairs for uniform treatment or vertical plate configurations for free-fall processing. The system claims to raise seed germination from 2-4 % to 40 % and to accelerate or retard fruit life cycles.",

        "For example, it is advantageous to treat seed bean stock having an untreated germination factor of from 2 to 4 % and render that stock 40% germinative.",
        "The materials to be treated are subjected to variable high voltage and high frequency electric fields, being passed therethrough for a period of time dependent upon empirical determination of effectiveness.",
        "The frequency of the energy pulses supplied to the plates is preferably maintained by an electric oscillating circuit...",
        "If a larger capacity is desired the widths of the plates 4 and 6 may be increased and the speed of travel of the belt 2 may be enlarged in accordance with the demand for additional capacity.",
        "It has been pointed out that large quantities of energy may be usefully expended incident to the resonant condition between plates 4 and 6 without, however, dissipating excessive quantities of waste energy due to resistance and electromagnetic losses."
