"this may spark a revolution in electronics as significant as the invention of the transistor, vacuum tube, and induction motor." How, exactly?

More destructive weapons. Of course I am being cynical, but that will certainly be one of the outcomes.

Maybe around the edges, but existing weapons are plenty destructive and many of them do not operate in an electronic regime except for control systems. Rail guns would probably get more effective but they're still not really all that useful and lasers might get more effective but again not really a material change to the battlefield, only an incremental one.

It's hard to develop a technology that can't be used by the military in some capacity but as such things go this one seems substantially more useful to everyone than useful to militaries.

Pushing this higher up, this is the first real expert commentary I have seen.

Someone posted a ChatGPT answer, which seems a pretty good response: Energy Efficiency: Superconductors conduct electricity without resistance, which means they don't produce heat as a byproduct.

So basically 'more efficient'? I'd dispute the 'dramatically' more efficient power grids, unless that's couched in industry terms - ie a 10% reduction in transmission losses might be 'dramatic' for energy grid engineers. But not really world-changing, for the rest of us.

Think of all the workarounds that we have to use to offset the waste heat and signal degradation of electricity (everywhere, including your computer/phone), and now imagine those things not existing.

My issue here is: This new material is essentially standard "high temperature" YBCO superconductor material just slightly modified, or? The authors are not doing anything dramatically new, like a new chemistry. How likely is it that all the other 1000s of labs doing research on this topic just missed this lucky combination of baking, cooling and whatnot?

It’s not a standard matrix and what do you mean by no new chemistry?

To create such a dramatic increase in critical temperature, I would expect you need a dramatic change in chemistry (as in: formula, materials,...) as well.

The space of possible combinations of just three different elements of the periodic table is huge. This is before you get into added dimensions of processing, ratios of each element to the others, different possible crystal structures, etc.

Q: Das Layout sieht Scheiße aus! A: Jo, das ist das historische Default-Layout. solid.

My German is poor. Does this say:

Q: The layout is very shitty!

A: No, it’s the historically default layout.

In a week there will be a lot of thinkpieces on how the internet got this so wrong. A lot of people just want to believe, full of hope, because their life situations (poverty, housing crisis, hot weather) are so dire.

I haven’t seen this get much play outside of HN and… those are not the problems facing most HN commentators

Just for fun: Am I the only one who thinks there's connection between this and the UAP news that's coming out? RTSC would probably enable a lot of incredible energy & maneuverability capabilities... Sorry, indulging in a little off-topic conspiracy theorizing.

I guess climate change will also destabilize society. But I know what you mean.

That is what I would call a slightly modified approach. They just "bake something together" and hope to get lucky. No way.

Anyway, I am not an expert. I hope they have a win here, but hard to believe at this point.
