Video: https://www.youtube.com/watch?v=EtVjGWpbE7k I really need someone to bring me down a notch. This is too exciting!

What material and setup could even fake that result?

Photoshop.

On reality, you would need a good computer with a large set of sound emitters just outside of the screen and a huge lot of tries. It would be a project for a small team and many months of work.

Or maybe a few transparent wires and less photoshop.

I do think the easiest way to fake a video like that would be to use a cool superconductor and change the atmosphere so nobody notices its temperature.

Word is one of the most common tools for writing papers. There was a study a while back that looked at the quality of Word or Latex papers. The study found that researchers using Word were more effective, and the working theory that explained it was that people who focused on the research did better research, and people focusing on the typesetting do better typesetting.

Latex is a waste of human potential. I've done professional typesetting and cataloging with QuarkXPress and InDesign both and it was extremely fast, that's for professional high quality publishing. .doc and .md is fine for information first publishing. Latex is not simple and is in my opinion just a big nerd snipe, its the intrusive thought of layout software, for humanities sake we'd be better off with simpler tools…

I think it would be nice if everyone can decide for themselves which software they prefer. Some people prefer Latex, others prefer Word or InDesign etc.

I would prefer not to have gatekeeping either way, both "It was written using Word, it must be fake" and "Latex should never have been invented."

Indeed, this will change pretty much everything if true. A true room temperature / ambient pressure superconductor will cause a revolution in so many fields that I find it hard to believe. But if... Let's wait for replication before throwing a party. This is on par with the discovery of the transistor and possibly bigger.

Superconductors have a current limit above which they are no longer superconductors. It is possible that a room temperature superconductor could be created that has a limit too low to be of any practical use. It seems this is worth cautious excitement, but don't get too excited yet.

The abstract says that T_c is 127 C, which should be comfortably above room temperature for most of the planet

You're not gonna get a noble prize for unverified results.

Ya no shit. Desperation makes people do dumb things.

You think this team would jeopardize their reputations by faking this data with such easily verifiable and thus refutable claims?

That video isn't very convincing. The usual test is that the material can float above the magnet.

Geopolitically infeasible, look at the mayhem caused by nord stream alone

Maybe it could be a stabilizing factor, because the many interests involved would be mostly aligned. However unstable Middle East is, most of the time no oil well is on fire, or in a war zone.

It is not about the steady state being unstable on its own, it is about how easily it can be brought out of equilibrium with a very small force (of a hand full of people). An inherent flaw in the centralized nature of such a system

This (or something derived from it) would be used for power delivery literally everywhere in the world. It might well be bigger in scale and volume than all the computers.

Superconducting power transmission cables solves the power storage problem of renewable energy sources. We'd just make a global energy grid, and the sunny side powers the dark side.

It solves them for some cost of power cables < $X, where X is the cost of the power lost in traditional cables.

If true, this should dramatically improve the timeline for practical fusion energy, right?

Not necessarily. While obviously it would be nice to not have to cool superconductors, it's not much of a technical challenge. Much more relevant is the strength of the magnets - fusion reactors need very strong magnets which is why they use superconductors, but there is still a limit to how strong they can be made. Unfortunately the higher temperature a material becomes a superconductor, typically the less able it i…

Ah interesting, thank you! Maybe I can hope that the discovery leads to further novelty then :) Maybe the same effect can occur in lower temperature superconductors as well. I guess there's a sweet spot for ease of construction, field strength, and temperature.

Simply using a lower temperature with a known SC would be an easy way.

He should hold it in his hand for 10 seconds before the test.

Dunno. A fancy tape or such made out of lead compounds would be a hard sell in comparison to ordinary copper for household wiring. But yes, for serious uses, this will be a big deal if it works out and can be made into a flexible cable. And I’m sure people will work on a less-toxic version.

Losses to resistance inside your home don’t matter much. In your computer they do, but it’s not clear this helps with that. This would enable really long distance electrical transmission, which solves the whole intermittency issue with solar energy.

If we can't handle / get motivation for long-line HVDC transmission I guarantee you we aren't going to be able to put together the will to make an entire transmission system out of a novel material with unknown mechanical constraints. Long distance transmission is not a solved problem, but it's close. We have the technological capability now to make much, much better transmission systems. We just don't want to.
