I hate to be stereotypical but I believe this is my medicine kicking in after a week of not having it and being able to hear a billion thoughts a second. Now I'm looking at hydrogen torches and what they're used for. Someone made a DIY one and I wonder if you could have a side gig as jewelry repair or something? Probably not.
It's so tiny I'm not sure what else you'd do with it. It's cool, don't get me wrong. I imagine it's more accessible than normal welding is. Debatable if that's a good thing. Maybe I should just give up on my whole IT thing. If I can't remember a shitzillion acronyms and tech from 20 years ago, it might not be worth it. Maybe Welding tests are easier? They have unions at least.
