Yup, no comparison with N.
I asked Philip once this question;
Dear Philip,
I'm all for Nitrogen but not with an exit-bag. So I would like to hear options of using Nitrogen in another setting.
Like: filling up a small space (like a tent or small bathroom) with Nitrogen in which you then temporarily reside with an oxygen-mask until the level of Nitrogen is high enough to put the mask off. I guess you'll then need a measuring tool and more than 1 nitrogen cylinder.
I truly hope you will address this.
Thank you and best regards,
And lo and behold, I got an answer back from the man himself;

At the time the existence of both gas and liquide was an eye-opener.
I assume, the liquid Nitro will immediately evaporate into a BIG gas cloud the moment you press that button inside the Sarco (correct me if I'm wrong).
@ here a wiki link about liquid nitro;
