The initial paper claimed superconductivity up until 400 K (127 °C or 260 °F), so I think if that's the case it would be able to withstand outdoor conditions just fine

Indeed, operating temperature seems to me less of a concern. Considering how difficult it‘s been to produce LK-99 so far, some skepticism on being able to manufacture the material in mass is warranted, I think. Still, exciting! I’m hopeful :)

Considering how people are making it at all, within days, with demonstrably poor instructions, seems to suggest manufacturing in mass has massive hope, once some time is given for refining the process.
