Hi all,
I used to work at a coal mine/power plant many years ago(before college) and built powerlines there for the drag lines to move to new digging spots. I once parked my truck under one of the big lines on a wet day and could not touch the truck without getting shocked. I also built a line crossing under another one of those big lines and could not touch the wire without getting shocked...even with leather gloves on....The induction field around those wires spreads pretty wide.


There are also cases of things like milking sheds built under power lines where the "step potential" (difference in voltage between two places on the soil, a step apart) caused the cows to be unsettled.


I would be rather easy to wind a large coil with the loops of wire running parallel to the power line and with a suitable cap, have yourself a 60Hz resonant coil to draw power from.


Getting a spark or a tingle is a long way from extracting useful power. Consider the spark from electrostatic charging on a dry day.
