It has been decades but what I remember is that, when I worked at an electric power plant where power lines emerging from the plant went over the parking lot, perhaps only when raining or high humidity, that if I moved my finger or umbrella tip near the car door handle, a very visible spark perhaps a centimeter long would extend between the handle and the finger and/or umbrella tip.
I am pretty sure this happened but someone told me this was impossible. If it really could have happened, what would you call the phenomenon I was observing?
I know that people who lived under power lines used to complain about health effects and if what I am remembering is real, it would seem to make such effects more plausible.
Note that these were the lines leading from the plant to an extremely large city -- I would guess there was a lot of juice there.
I don't recall that the spark was painful or there were any health effects (although who knows -- I did start to lose hair but there could have been other reasons) but it was concerning at the time.
