Re: What about removing...
"The key question is what this 'Magical Gas' is ?"
Sorry, I should have been clearer.
I was thinking of removing the O2 via a pump, and thereby creating a (partial, or better) vacuum - rather than adding a "Magical Gas" that "used up" or even replaced the O2 (and assuming Halon is not suitable/acceptable etc).
BUT, if the batteries are creating their own O2, then sucking out any original O2 that was in the MegaPack won't really help. :-(
