This is huge, is it not? No loss in potential energy means that I could have an infinitely floating coffee cup without the use of power, no?

Room temperatur 127?? You fucking kidding me?

To be honest, this seems very sus to me. A big paper with only three authors?! I went down the rabbit hole of trying to find the lab from which it has been published. It's almost there is no online presence. In another paper they put out along with it, they say that they show Meissner effect (levitating effect of a superconductor) and that a video is attached. I looked for the video but I wasn't able to find it. :/
A big paper with only three authors?!
That part isn't so unusual, especially in condensed matter, where labs can be relatively small. For example, the paper announcing the discovery of high-temperature superconductivity in 1986 only had two authors (Bednorz & Müller).
I went down the rabbit hole of trying to find the lab from which it has been published.
For those who didn't look into the paper: They seem to work for a company called "Quantum Energy Research Centre, Inc.", which does sound a bit... woo-y to me. At least the third author seems to work at Korea University, which, according to Wikipedia, is relatively prestigious. Who knows, maybe the authors just can't be bothered to use Latex and didn't choose the name of the company or didn't put too much thought into it, but for the moment I'm also rather skeptical.
Yeah, in olden times sure. You can say a big paper like EPR paradox one, was written as only three people. These days, a lot of people would jump on a big paper since citations is the currency of research now.

Here we go again...
anyone with a better understanding able to articulate potential trade-offs/complications to using this in practical applications?

the critical field and critical current seem very low … This means you can't actually push big current through this thing (yet). You can't make a powerful magnet, and you can't make viable power lines
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)
Read this comment thread from SC researchers: <reddit link removed>
Lots of problems with the paper, they claim. It is not up to the standards of current SC research. One of them says Dias's work shows more merit than this.
Insane capacity batteries
Lossless power transmission via wires
Better magnetically levitating trains
Much more power efficient computers, electronics
The list is huge
no i know many of the applications, its huge if true! i understand that, but almost everything like this comes with trade-offs, and i was wondering if there are any here that would make it non-viable for some/all applications
The claimed saturation current is very low. If this is inherent and not just a first-try thing it will be less-good than permanent magnets for doing many magnetic-field things and less-good than Aluminum for some current-carrying things.
It's a perovskite, in semiconductor applications these have stability and durability problems.
It might also be a scam. This would make it useless.

If this were true they wouldn’t have released this, they’d have released a room temperature and pressure superconductor and instantly become billionaires.
If they take too long the room temperature won't be enough due the increase in temperatures 😅 /s
Tc is allegedly 120C, so we,ve got a couple of years if it's not a scam.
Maybe it's me misunderstanding, but 127 is considered room temp?
127c is the maximum operating temperature. If it goes above that, it looses superconductivity.
This material below 127c (which is insanely hot for superconductors) will be superconductive.
Operating range is -273c to 127c
