Kite Handle
If you suspend a copper wire (no ground) of a kite or a balloon, static buildup?
The day would be bright and sunny with a little wind. A mechinism handle the cable, I would not be near him.
Air moving through the wire that tend to generate an electrical charge but might not be enough to overcome the leakage current path through the air. Depend on how much area coper is exposed to wind, wind speed is blowing, and moisture. If the end of the cable insulation of the earth and uses a very high resistance voltmeter, you can easily measure the voltage. If you know the coper area can calculate the amount of charge collected.
