I've noticed a lot of folks are using FM-200 now (U.S. Patent # 5,124,053
for those interested). I unfortunately don't know much about it,
but they seem to have a lot of propaganda at
http://www.fm-200.com/.
They claim that it's "People Safe", and that FM-200 is used in
pharmeceutical inhalers as propellent. That doesn't necessarily mean
I'd like to breath it instead of oxygen, though.
