Interesting that some people make a joke of it. Look up Brown's gas on the web. I don't believe it will do everything "Joe" says it will, but if some of what I hear about Brown's gas is true, it would be very useful.

Weld dissimiliar materials. Galileo predicted the fusion of dissimiliar materials in a vacuum. Brown's gas is supposedly a collapsing flame. Something like 1900:1

Sublimate tungsten. You know what temperature that is???

Melt firebrick.

You can buy Brown's gas welders out of China. The quality is poor.

Several months ago I had a hand injury that required a hospital visit. For reasons I can't remember, the surgeon that was stitching me up mentioned Brown's gas. He had been using a Brown's gas welder the weekend before. He mentioned some of the things I have heard. We talked about them a bit. Run your car on it? No, but welding, YES! I hear the cost of operation is about the same as a Tig welder, but the versatility is much better.

I'm not affiliated with this outfit, it was just the first link in my search. I'm sure there are lots more.
