Piezo-electricity.................
mechanical motion produces gobs of electricity
never heard of that before - does that make golden pinkish colors too?
One Oct morning 2011 in north Jersey my mom and I saw the whole sky and air outside had this rolling golden pinkish coloring it was after sun rise maybe like 8am, it lasted about 10 minutes from the time we first saw it out the window, rolled from east to west. we took pictures. no one else seemed to see it, never saw any news reports on it either from that day.
yes
Yes, either the piezoelectric or triboelectric (friction) effects.
