Good information on Propane is hard to find in the US right now.
Nolff's put out a good book but they were bought by Woodward. They may
have some left. Larry Carley wrote a book, Jay Storer wrote another.
Use interlibrary loan or eBay.

Bret,

What a disgusting thing to say.

I wouldn't even say something that nasty to Bill Clinton himself!

Hmmmmm, maybe if I had a 1500hp monster truck.....

I was reading that, at least, propane could be used to replace the AC
refrigerant. http://en.wikipedia.org/wiki/Propane
and there was an interesting gas-absorption refridgerator with no moving
parts that can cool directly from heat energy.
