That's a new one. I hadn't heard that one before. I'll have to add it to
my list of other ones.

If the Earth has an excess of electrons and some of them move away to some
distance, what is it that causes a voltage difference to appear?

FYI, I've been in a location with a clear sky that had more "charge" than
other areas. After noticing my 2m ham antenna on the car was giving me
1/4 inch arcs to the frame of the car, I decided it was best to leave the
area. The sky was clear. By the time I was 4 miles away, the spot I was
at had big cloud starting to billow up from it.

So why that one spot and not another spot in the same clear sky?
