Why is it not used more often? Gas cooling that is.

You can use heat to cool something. The process is called an "absorption refrigeration cycle." My parent had a refrigerator that use a gas flame.
Without going into the details of an absorption refrigeration cycle, I can tell you this. The refrigerant used can either be ammonia gas, or something called Lithium Bromide. Both are used in large commercial applications where gas or low pressure steam are available.. But the cost of the lithium bromide system, and the hazard of ammonia systems, has made them non-competitive for home use.
One thing to keep in mind....both systems mentioned above still use electricity to run pumps and controls, but not a compressor. So the big energy use is the natural gas or steam.
If you really want to learn more about absorption refrigeration, just do a yahoo search with key words "absorption refrigeration".

Rich answered your first two questions. As to why it is not used more often, it's because it is more expensive than conventional systems and is relatively rare to be found. Not many techs are trained for gas systems so finding a repairman can be a nightmare.

My parents had an a/c unit that was gas about 30 years ago. It worked just fine. I don't know if they're used anymore.
