  I recently saw a DuPont advertisement for what they claimed to be
a replacement for Freon, in freeze sprays and other aerosols.
It is called Fluorinert, and supposedly doesn't damage the ozone
layer or have any other side effects.  (We'll see....)
It's not an entirely new product; they've been using Fluorinert as
coolant in Cray computers for a while.

  I don't know if it's on the market yet, or what DuPont's plans
are for it. But if it replaces freon, I'm certainly looking
forward to it.
