    "concept_summary": "Plauson's system uses thin metallic leaf balloons equipped with sharp, ionizing pins (zinc-amalgam, radium, polonium) to collect static charge from the atmosphere. The collected charge is rectified into continuous current pulses and can be stored in condenser banks or used to drive an electrostatic rotary motor that operates without conventional coils.",

        "A single balloon sent aloft to a height of 300 yards gave a constant current at 400 volts of 1.8 amperes, or in 24 hours over 17-1/4 kilowatts!",
        "By using two balloons in connection with a special condenser battery, the power obtained was 81-1/2 kilowatts in 24 hours. The actual current delivered was 6.8 amperes at 500 volts.",
        "The balloon, when made airtight, is filled with hydrogen or better, with helium. The outer surface is dotted with extremely sharp pins, made sharp electrolytically.",
        "The pins themselves were made from amalgamated zinc, containing a radium preparation, in order to ionize the air.",
        "By sending up a second balloon with an antenna to the same height at a distance of 100 meters from the first balloon, a current of over 3 amperes was obtained. Then by putting into the circuit a large condenser ... the current rose to 6.8 amperes with about 500 volts mean tension."
