Wow! Weird?
I found a oxygen concentrator a few days ago, attached ropes to it and carried it the ten blocks to home.

I never ever thought I'd find one, ever. This is a beige (not a word we use in NZ) ' suitcase on its side' sorta one.
The oxygen concentrator thing is something I have seen on American TV shows, but I have never seen one used in NZ.

So, I took it home thinking if its got a plug, its probably got a motor or pump, since there's a gas fitting on its side, Copper or Brass piping. And a gas flow meter.
But, I was sorta thinking that I maybe be able to use it for ozoneosis with a industrial ozone generator. For fun.

OK, when I get home I will have a look inside it.
