It's a conductor of electricity. But super good at it. i.e. - It has zero resistance to electricity. Currently, the best superconducting materials we can create have to be chilled to near absolute zero, which means designing them to work in liquid helium baths. This is expensive, and difficult. If a material can superconduct at room temperature, now we're talking usage in general purpose consumer goods. As for why we…

Would help with fusion, right?

It would make fusion experiments cheaper, but not more successful.

But now we know its possible, maybe they can figure out the structures that make it work and develop better materials?

I'm hoping for something that isn't made entirely out of a superfund site material, personally.

Unless I misunderstand what you mean / what the stuff is made of, this seems like a huge exaggeration... lead isn't friendly, sure, but it isn't that dangerous? There are worse materials that are in common use. (And we use lead in plenty of places already)

Mostly, I am just glad that all the LK-99 posts are drowning out the "AI" news for a few days.

But fear the news if it is discovered that LK-99 increases AI performance.

A planet completely populated by electronic beings.

Single-celled life, multi-cellular, mushrooms, trees, whatever ate lignin, dinosaurs, rodents, humans, Electric beings? I mean, there's nothing 'unnatural' about a world populated by robots, we just assume that 'alive' means 'made of meat', but the raw materials in a robot and a human are all Earth based.

If it's real, how fast could we see concrete applications using this material? 5-year time frame? 10-year time frame? More?

You'd need breakthroughs in the manufacturing of it (yield, process, scale, etc) and then building the infrastructure and supply chain to support it. Depending on its availability you could see governments hoard the material for "security" and "public interest" use cases, etc. Military first as usual.

If this turns out to be a super conducting material you can be assured that overnight there will be many thousands of people all around the world, from academic, corporate, government, and private labs working with the new theory and materials and discoveries will occur as our understanding of the phenomenon get deeper and wider. There will be so much incentive to find new methods and materials that have the properties of this material.

That's what I meant. It states energy density as 40 kJ/L. Lithium batteries have energy density up to 2.5 MJ/L. Fossil fuels and hydrogen way more.

That 40kJ/L is for the entire system including the cyronics. Get rid of the cyronics and the system gets far far more energy dense.

Yes, that's quite likely how they come up with this number. But is it enough? What's the most energy dense configuration that can be made with room temp SC and does it compete with lithium batteries?

The fun part about this is how easy things are to grasp even though I have zero background in the science.

It certainly doesn't hurt that this thing levitates . No need to squint into a microscope, parse a screen full of numbers, or try to make sense of false-color renderings. Either you have video proof of a levitating object, or you don't. The demonstration is as intuitive as it gets, despite the fact that the theory is crazy difficult to wrap one's head around.

Levitates? Against, what, the earth's inherent magnetic field? Sorry, I haven't seen any visuals that show this behavior.

Don’t be. Twitter/X/whatever they’re calling it this week is crawling with Pepe investment bros talking about bullish sentiment because superconductors equals singularity musk crypto AI blah blah blah. It’s bad. It’s really, really bad.

Yeah, hnews is the place to be, nobody here is ever excited about anything new.

AI has already taken over the internet and is just feeding us news stories based on what it already knows. Super conductor discovered by a team who's been searching for 20 years. Internal conflict 'proves' there's something to argue over. Low quality, confusing information that's hard to decipher, but kind of makes sense. Asian language information streams and videos. Musk buys twitter. A submarine visited the titani…

If you want a tinfoil hat, consider that the LK-99 news dropped around the time that the US military is being exposed for having RTRPS tech flying around for decades

RTRPS is presumably "room temperature room pressure superconductor"

Throughout this whole saga I've had this feeling that at the very least we can rely on China to really pursue this new development to it's logical end. It's kind of sad, but I don't think I can say the same about the US at this moment. You know for a fact China's going to JUMP on this, figure out if it works or not, and iterate.

I don't get the "disappointment" with USA scientists in this thread not having yet published a replication. There has only been one weekday since the LK-99 revelation came to light. Have some patience. The analysis from this article is a publication from Berkeley National Lab that has already come out, and Argonne National Lab has announced they have synthesized the material as of yesterday and will release results f…

I'm astounded that the MSM seems to be ignoring this ATM. I did a Google news search on LK-99 and saw nothing from major publications. A search on the NYTimes returned an article from 1974.

I think them waiting until there’s more research is preferable to them coming out and making random claims which pan out not to be true.

That hasn't stopped them in the past...
