Hi Troy

Interesting topic and just wondering about the cost-to-gain? How much is a salvaged kilo of gas worth and when do you break even after having bought the (assuming fairly pricy) freezer?

Cheers

Nic, this one wasn't that expensive although I'm not intending to gain or break even from it. Although if I finish up making my own N2O, then I probably will. It's something I've been looking at for a while now and can be handy for some auxiliary applications eg. chilling elastomer stock for clean machining of special gaskets and keeping Trout fresh for eating over time (my father, like Pete Lamb enjoys his Trout fishing and I enjoy eating them, so long as they're *fresh* though). Keeping fish like this fresh over time requires -60C or below storage.

Cheers,

you could always catch a new fish?

Seriously though, that sounds like a neat project and I look forward to hearing the results/seeing the progress of your own N2O.

That’s it! I’m not letting you bloody queenslanders anywhere near my wife when I’m negotiating such purchases :P

Just been informed by Norm that a D bottle from BOC is now $265 :evil: :evil: :evil: :evil:

Time to talk to Air Liquide to see if an account can be setup, until we can make it ourselves.

Outrageous!!! I just filled up last week for my previous price and I was pleasantly surprised to beat this year's round of ball gouging price rises.

It sounds as though things may not be quite as bad as they seem... I spoke to Norm a few days ago, and it turns out that it may actually be a balls-up on the part of BOC. It seems they mistakenly charged him a fairly hefty delivery fee when he collected it. The actual cost of the nitrous was in the order of $180 +GST. That said, it still seems somewhat OTT. It will be interesting to see whether Air Liquide can supply nitrous, however I have a feeling that they only supply medical N2O.

The $100 for a D-size bottle of acetylene was a kick in the teeth, so I'm not thinking they'd be pulling any punches on any of the other gases...

Troy, I've been reading this thread with interest. Did you have any success with homebrewing your own nitros?. It wouldn't appear to be to difficult based on internet information but whether it's viable on a worthwhile scale!!!!!!

No I haven't even tried yet. I agree it's probably not terribly difficult to do, although you have to keep an eye on controlling the decomposition temperature. It does help a lot having the capability to chill the N2O down to a condensed phase without pressurization. N2O's decomposition (especially catalysed decomposition from say stray organic contaminates) is very pressure dependent.
One of the reasons I've not actively pursued that area of tinkering is that BOC's N2O prices have stabilised over the last 2-3 years and there's also growing competition in that market with more and more smaller suppliers entering the market. Even Supagas (here in Melb at least) are now supplying N2O at very competitive prices and are keen to do business.
