Do they have enough oxygen and doesn't that get dirty fast like algae?

Sickening. Absolutely sickening. How can these pieces of shit live with themselves? "I think we should seize it." Fuck you, you waste of oxygen, you goddamn piece of shit thief.

Considering the kids oxygen setup I just figured a Darth Vader helmet would have made more sense. The juxtaposition of cute kid/symbol of galactic oppression does make for an odd commercial.

Flux core would remove any slight oxidation between deposits on a continuous weld, or a media blast nozzle in front of the weld zone.
I agree with you if they intend to use it for load bearing structures, but it wouldn't be difficult. Just a loose seal around the work area and positive gas flow keeping oxygen out, problem solved.
The downside I see is cost. It's expensive to 'make metal' with a mig....or any welder. Electrodes/wire aren't cheap, and then there's the electricity. Bending or milling sheets, castings, or blocks is almost always going to be cheaper. This will be useful for designs that require complex interior shapes impossible to do conventionally, but not much else, imo.

Did some more digging.

We breath an average of 11,000 litres of air per day: https://www.sharecare.com/health/air-quality/oxygen-person-consume-a-day

That amounts to 11m^3 per day. So if you lived in a basement with the highest acceptable radon levels, you'd take in 11*150Bq worth per day, or 1650Bq per day. If the prior Idaho reference numbers follow, then living in a basement on the upper limits today is the same as drinking a kg of this undiluted waste water daily.

From that angle it looks like the 'radioactivity' problem is pretty tiny, given that even undiluted you have to drink a fair bit to match current standards for daily radon exposure.

I think the"air" they fill the bags with is really oxygen or an oxygen rich mix. Just air wouldn't keep them alive for long, even sedated.

Wouldn't have anything to do with Nitrogen removing all oxygen from the combustion? \= |

I was watching one of those air crash investigation dramacutaries about the Lear Jet crash that killed Payne Stewart. The first action on the checklist for depressurisation was some troubleshooting. The pilots never got to action two, which was to put on their oxygen masks.
