I've been told that there is now evidence that the ban on freons
(including Halon) has had zero effect on the Ozone layer but that the US
government is unwilling to admit that it was wrong about the relationship
between freon and the loss of the ozone layer.

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.
