I get the idea of superconductivity at room temperature in theory. But I don't have enough knowledge to understand in real terms, how will the world change if this is true?

You know all those bird scooters people leave lying around cluttering up the sidewalk? With a room temperature superconductor they will become hover scooters cluttering up the sidewalk!

And all of the high voltage transmission lines we want to build but can’t because of permitting reasons would have zero energy loss if we actually built them, which we won’t.

Maybe success in life and science isn't about becoming a billionaire? Even so - if this works out, their prizes and paid speaking gigs will cover a very comfortable life if that's what they want. I'm not sure why they should be entitled to more than that.

If it pans out I'd rather they become billionaires than your average tech bro.

Hey Jacques, It's been fun watching your comments on this, you're very knowledgable. :) I had a question, I see some "we made a totally perfect/pure LK-99 it didn't work" - is pure/perfect what they should be going for, to me perfect/pure != correct, however I knew literally nothing about this subject till this week so I have no idea what I'm talking about. Thank you.

I hope they're as weak as possible. The worst possible outcome of a room temp superconductor being discovered is stifling innovation to make money off it

I'm generally anti-patent, but if there were any valid case for patents, this is it. Long, hard labor to discover something entirely new that has massive uses for society. I'd rest my hopes on them not being dicks about it, not on them not getting benefit from it.

Long, hard labor should be rewarded. And it is. They're receiving a salary, and now fame. That's more than enough.

For one, lossless storage of electricity.

I think you mean lossless transmission? If we can actually replace transmission lines effectively with it, unclear whether it's practical for that yet.

Also energy storage: https://en.wikipedia.org/wiki/Superconducting_magnetic_energ...

So far lab replication efforts are: Two from HUST: https://www.bilibili.com/video/BV14p4y1V7kS/ https://www.bilibili.com/video/BV13k4y1G7i1/ One by USTC https://www.bilibili.com/video/BV1Ex4y1X7ix/ this tiny sample can stand on its pointy side. One by Qufu Normal University https://www.zhihu.com/zvideo/1669820225079070720 One with THU background but claims a personal project https://www.bilibili.com/video/BV14z4y1s7V…

> Why are't more labs outside China making LK-99 and publish videos? Good rigorous science takes time to produce. It can take anywhere between several months to a year or more, and the career implications for rushing something out that is later found lacking is not great.

While it's true that good science often takes time, I believe it's not necessarily the whole picture. In fast-paced and rapidly evolving fields like this one, swift and open sharing of progress can be incredibly valuable. This is evident from the recent developments in AI and large language models (LLMs), where real-time collaboration and data sharing have led to exponential advancements.

Is this actually true?

Almost instant battery charging for example.

Both. There are coil based ideas for storage.

For those experiencing this type of "black swan, but good" event for the first time, it is helpful to recognize that the human tendency to believe that all future "big events" will be dystopian downers, is statistically unsound. For a while I've kept a list of the things that could be "good" swan events, but to be fair I didn't have "room temperature superconductor on that list" :-) Other things that could happen: 1)…

I like the idea of this list. Some others: - Quantum supremacy - HIV vaccine - Synthetic life - Discovery of ET life - P vs NP solution

Low cost carbon capture

1) Subset breakthrough here potentially related to cancer, we'll see how the peer review and evolution to becoming an available standard of care goes.
