I think it must be global warming which excites electrons. I have been able to stabilize the disks for up to 4 hours when I use their "atmospheric equalizer" which changes the atmospheric pressure from 760 to 763 by making the nitrogen content 79.5% rather than the usual 78%. This also has a profound effect on the listening experience as it is well known that NO2 conducts soundwaves the way they were meant to be conducted.
