It seems a third paper was just found an hour ago. Original paper: http://journal.kci.go.kr/jkcgct/archive/articleView?artiId=A... Translation: https://www.docdroid.net/UiUrs8c/kci-fi002955269-1-pdf Translation source: https://twitter.com/andrewmccalip/status/1684700783852556288

The first sentence already raises a big red flag. "This paper examines the way of thinking and limitations of physicists regarding the phenomenon of superconductivity". Stop these ridiculous presumptuous claims about "limitations of physicists" before the work is actually verified and proven.

Koreans have a mean and antagonistic streak, that's why they're so good at making dramas, but still outrageous opener lol. I wonder if Korean academic culture is different from ours.

Why is replication of material production the focus when the material ostensibly exists and can just be tested for superconducting properties?

Because this ensures repeatability of the material, that it wasn't some accidental dopant, that the samples weren't doctored, etc. Essentially, a clean room check on all claims.

If any chunk of material can be shipped around and shown to be a room temperature superconductor at independent labs, that would be a revolution.

Then they can worry about reproduction, as every materials science lab on the planet would be trying to reproduce it at that point.

The median prediction for whether this gets independently confirmed is sitting at 25%: https://www.metaculus.com/questions/18090/room-temp-supercon...

Looks like I need to give some sucker 3:1 odds to take his money. Anyone want to bet it’s real?

Now down to 19%. Starting to stabilize, at 143 forecasters.

Alright, I’ll give you 10:1 odds.

Some schmo with an instant coffee company. There's no need to surface random people's opinions.

1000 to 1? Dollars to bitcoins? Shares in their room temperature superconductor monopoly?

Does this mean there would be no heat waste? And devices like phones and computers wouldn't get hot?

One of the biggest use cases (for superconductors that meet their requirements) would be long distance power transmission, where as much as 30% of the power is lost over long distances. Essentially, (and very top level) you could produce 30% more power, without adding any more production capactity.

HVDC has losses of more like 3%.

Portable MRI would be a huge deal. We'd also see superconducting motors in electric vehicles, along with marked efficiency gains in every part of EV systems. We could have a superconducting power grid with solar panels distributed across the planet. Superconducting batteries could give us grid level storage. It also reduces the cost of hypothetical fusion reactors, their magnets can be cooled with unpressurized water…

Those won't happen with the current magnetic field limitations. Ironically, this is the thing that makes me believe them more rather than less: it is plausible that if you find a material that is superconducting at room temperature that it isn't right away going to be ideal in every other respect, and it would have been very easy to fake that one too.

Right. Assuming this paper is true, just knowing that a superconductor with a critical temperature over 100C can exist at all is a huge leap forward.

It should lead to a huge push to understand the physics of this new material and building better materials with more useful properties
