The method to produce this material as described in the related paper [1] is fairly simple and could be done at home with a $200 home metal melting furnace from amazon and the precursors (which also seem to be fairly standard easy to obtain metals).
If this is real, I'd expect some smart people from hackaday / youtube to reproduce this within weeks if not days.
If this is real, it'll change society quickly and permanently for the better. There's obvious wins in energy transportation and even generation, but actually having a room temperature superconductor is likely to result in an explosion of engineering use cases. It will be like the discovery of lithium ion which slowly transformed the use of energy throughout society, but faster.
Hopefully it repros.

- Maxion 3y agoYou need a furnace that can hold a vacuum, though.
- local_issues 3y agoThere's a surprising number of them around. I think the bottleneck for quick repro will be mat sci people, not equipment.

- overnight5349 3y agoIn the paper, they sealed the material in a quartz ampuole under vacuum. I wouldn't call it an easy process, but it's achievable without highly specialized equipment. Just a torch and a vacuum pump.
- MisterTea 3y agoThose are easy to make.

- lazide 3y agoAre you saying superconducting railguns could possibly cause problems?!?
- post-it 3y agoThey could only cause problems solvable by more superconducting railguns, so they're a net zero at worst.
- JumpCrisscross 3y ago> could only cause problems solvable by more superconducting railguns If the projectile is ferromagnetic, or potentially even just diamagnetic, a defense system involving shaped ultra-high intensity magnetic fields becomes conceivable.
- Arrath 3y agoHopefully they don't cause solar system wide loss of consciousness events.

- VMG 3y agoPlease don't blow the lead smoke over to your neighbors house though
- Roark66 3y agoSeriously, people should stop panicking about lead that much. You know there is this fairly common hobby people have, it's called casting bullets. With lead. I've done it, I know many people that do it regularly and they're all fine. Furthermore, shooting ranges are full of lead in the ground. The laws around here(Poland) require a cleanup by specialised companies every few years and a concrete slab to separate the lead/soil mix from the groundwater near the targets, but still there are tons of the stuff just sitting there for years and no one gets hurt. Fun fact. These specialised cleanup companies don't cost anything for big ranges. They're either free, or they pay the shooting club that owns the range money, because the lead they recover is worth a lot.
- sebzim4500 3y agoYes lead in the ground isn't all that scary. Lead in your body is a concern. So don't blow lead smoke over your neighbors house.

- CamperBob2 3y agoThis post is what happens when chemistry sets don't contain anything more hazardous or interesting than marshmallows.
- sebzim4500 3y agoI think it's more that a generation of people grew up with lead paint and that decreased the average IQ so much that you have people suggesting that lead smoke is harmless.
- marcosdumay 3y agoOk, let me just add the obvious disclaimer: don't try this yourself unless you have a pretty good understanding of chemical lab safety. Really. It's more likely that you will contaminate your land, and possibly your neighbors land too than that you will manage to replicate it.

- hinkley 3y agoWhat do you suppose the odds are that there's a Tin-based compound instead of lead based? (Which would effectively make a bizarre form of brass a superconductor)
- marcosdumay 3y agoI doubt this one chemistry will be all that useful on practice. But after people understand it, I expect them to recreate the effect with completely different components, not on just slightly different ones.
- ivalm 3y agoNot really, cuprates have been the standard for high Tc superconductors since 1986 and nobody could replace them with easier to work with materials.
- Jolter 3y agoBronze, right? Brass is copper and zink.
- hinkley 3y agoI swear I typed bronze…
- m463 3y agoYes, but chernobyl produced a lot of useful electricity (at first)
- JumpCrisscross 3y agoIs the superconductivity present in the powder? Or does it require vapor deposition? If the latter, it implies a cloth versus fibre topology, which forces an interesting rethink of many paradigms forced by the ductility of our present conductors.
