1 particle of freon stops roughly 10,000-15,000 particles of O4 from forming.

They should keep all their sheep indoors and then they can collect the methane gas off of the ceiling and use IT to keep themselves warm instead of using the sheep.
If methane is a greenhouse gas and you were to burn it in a IC engine what would the emissions be?

Eh, I have a somewhat small 36" tall one. I had forgotten about it as I was around 16 when I made it. I never really got around to tuning it too well, but I used a rotary spark-gap made from some motor I had layin' (think it was an airconditioning fan motor). Power came from a Lincoln 220v crackerbox. Duty cycle on it before cables melted was about 20 seconds. I think I fired it a grand total of 4 times. The longest arc I made from it was about 4' My stepfather figured out all the really fine details. It was great to say the least, we never did get to use it's output at 100% though. May have to dust it off and have some fun with it

ODS include CFCs, HCFCs, halons, methyl bromide, carbon tetrachloride, and methyl chloroform. ODS are generally very stable in the troposphere and only degrade under intense ultraviolet light in the stratosphere. When they break down, they release chlorine or bromine atoms, which then deplete ozone.
I was going to try to find a rule of thumb for gasser versus diesel in greenhouse gasses emitted annually but I can't find the information, let's just say a diesel let's out roughly a third of the greenhouse gasses that gassers do.

Made a few of my own windows in my addition to the cabin recently. If I were able to harness a fart between the paines of glass, would it help insulate without fogging up every time it rains?

Well, I'm not convinced the Ozone problem is real or caused by CFC's. There are a lot of people who believe that the reason CFC's got banned was because Dupont's patent expired and anyone could make/sell freon. So who has the patent on R-134A?
Freon is about 6 times heavier than air also so how does it get into the upper atmosphere to breakdown ozone?
As for global warming, the climate model was tweaked until it rendered the results the green scientists wanted. It was found that if you fed noise to the same model it rendered the same "hocky stick" upswing in temperatures. This completely invalidated the whole model and chicken little global warming scientists theories.

R-134a is an HCFC which really isn't much better than Dupont's R-12 which is a CFC. The HCFC was supposed to breakdown before it gets to the stratsophere but I don't believe it is happening as planned. As far as I know there aren't any exclusive rights to any of the freons anymore.

HOW?

Chlorine is the bad actor in the refrigerant/ozone depletion mechanism.
R-22 IS an HCFC but since it is a much more hydrogenated molecule, it contains WAY less chlorine than the old CFC's (Freon-11 and Freon 12 etc.) ever did. That's why R-22 was allowed to remain in use for so much longer than CFC's even though it had an atom of Cl.
The hydrogenated(HFC), or mostly hydrogenated (HCFC) refrigerant molecule breaks down much easier at a lower UV energy level than the very tightly bonded CFC's.
The problem with 134a is it has a larger GWP or Global Warming potential than R-12 did.
Get rid of one problem and you have to deal with an other...
R-134a in some applications(centrifugal, stationary hermetic, etc.) is MORE efficient than R-12!
Different compression ratio's and improved condenser performance makes all the difference!
You're right about the exclusivity statement. The molecule is not patented, but the processes to get there and the trade names are! There are many ways to skin a cat but some are sure messier than others.
