We need to remember that even if it is a room temp superconductor (and it might be, probably not), that doesnt mean it will be practical. It has a very low critical current, measured in milliamps making it unusable for magnets or energy transport. It is lead acetate meaning it has roughly the mechanical properties as... rock candy. We probably wont be able to use this for any sort of cable.
Still, this would be huge if true, most likely a new mechanism of superconductivity, with new models, making it eadier to find room temp superconductors with more favorable properties.
There's a video of it levitating by the authors here. https://sciencecast.org/casts/suc384jly50n Despite room temp superconductors being the most dramallama area of physics stuffed with...
Despite room temp superconductors being the most dramallama area of physics stuffed with retractions and results which can't be reproduced, this is probably one of the more convincing announcements I've seen. At minimum, I'd wait until this passes peer review for judgement though.
The thing which intrigued me most is that the simple recipe seems doable for a DIYer with a few grand in vacuum and autoclave equipment. It's a simple baking procedure not too different from the Yttrium superconductors undergraduates sometimes make in university.
Right, Im just saying even if it is (and with that vid, im cautiously optimistic), it may be unsuitable for the applications the public thinks of when they hear the term.

One of thr biggest issues is transporting energy to where it's most needed. Having sunshine in Arizona doesnt help Michigan.
But if we could build zero resistance transmission lines all of that could change. I'm sure there are implications in energy generation efficiency as well, but I don't know enough to know how significant
Yeah I'm calling bullshit just based on it being too good to be true. They have a follow up paper with a better R-T plot, which looks pretty weird to me. They're explanation of the mechanism is...

I don't know this group, so I'd guess unlike Ranga Dias' group there probably isn't any scientific misconduct going on. I suspect there's a measurement/interpretation issue. I hope they let other groups test their samples
really interesting although it's only a pre-print as of now so we will see if it gets accepted and actually reproduced. lots of papers about room temp superconductors got published and the...

The interesting parts of this paper (and it’s companion) is that the main author has some very well cited papers in the space, and the paper contains in the supplemental material a very easy to follow process for recreating the material. It isn’t even that exotic of a process. This should be very easy to replicate, probably some people could even do it at home!
Yeah. Not sure how far out we’d be from production but if this is true it’s world changing news. That said I remain skeptical. It’s just such a huge breakthrough I feel like there’d be more coverage

Definitely, I agree with your recommendation of caution here. 🖖

What's wrong with Ranga Dias' work?
I've seen it in the news recently but I haven't seen anyone give a proper breakdown of what the deal with him is.
Here's a decent article from today.

Funny how just today I was served an article from Nature about fraud in room temperature semiconductors
