John M. said,
"This was a rare failure, no doubt; and no chance to keep the freon from
the Stratosphere. I later checked, 1 lb of freon is worth 1800 lb of
CO2 in ozone destruction, so perhaps several tons of CO2 equivalent went
up, like a couple of tons of best anthracite, burned smokelessly as yet one
more contribution to Global Warning.

Very sad!
One serious contributor to greenhouse gas effects in the stratosphere today
is SF6. It is used by the grid to prevent damage from arcing in the
expensive, large power switches. Some of you know SF6 gas because it is
used in physics for certain fun demos about sound. The SF6 gas molecule is
amazing. That damn gas stores 40,000! times more energy than CO2 gas, by
volume because it has many modes of oscillation in the IR.
Greenhouse warming by the grid is protected because Energy *MUST first* get
sold back to the grid, then *secondly MUST* be repurchased from the grid.
You cannot directly produce Solar, store it and then use it without the
grid. This is true if you live connected to the grid. I am not sure if it
applies if you live in an off-grid community. The energy distribution laws
protect the grid and make it grow as we move to green energy. But a harmful
greenhouse effect comes from the SF6 that it uses.
