If manufacturable at scale, does this allow for MRI machines that could operate without perpetual consumption of liquid helium?
And potentially reduce the cost of fusion reactors by tens of percent.

Re: The first room-temperature ambient-pressure superconductor?
#162The method to produce this material as described in the related paper [1] is fairly simple and could be done at home with a $200 home metal melting furnace from amazon and the precursors (which also seem to be fairly standard easy to obtain metals). If this is real, I'd expect some smart people from hackaday / youtube to reproduce this within weeks if not days. If this is real, it'll change society quickly and perman…
You need a furnace that can hold a vacuum, though.

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.
That won't save us. Not unless you know how to build it in the next 5 years.

#164Insane if true. Unlocks a completely new chapter for the human tech tree.

As someone who knows more about words than superconductors, gentle correction in case it is an actual misunderstanding instead of misspeaking, but a correctly running MRI shouldn't ever CONSUME the liquid helium, it would recycle as much as possible. But as a newly self-proclaimed expert on superconductors as well, yeah this would probably help MRIs. My understanding is that the reason for superconductors in MRIs is…
Liquid helium is very sneaky stuff. Sure, they try to keep it in as much as they can (it's expensive!) but it's gonna leak eventually. A quick web search indicates that MRIs in common use lose 1-6% of their helium per month.

#167This is almost certainly a mistake at best or completely bogus at worst. Reminds me a bit of that situation with someone who claimed they had evidence of successful human cloning - when it turned out all their results were lies.
If it is true, it would be a revolution for nearly every field. So I certainly hope I'm wrong!

#168its been 4 months since they first synthesized it !

Let's hope so. The easiest way to convince the world that you have a room temperature superconductor is to make up a big batch of samples and offer to distribute them to national labs for testing. First test, does it levitate a small permanent magnet, demonstrating diamagnetism?
They have photographs of that on page 7 of the sister paper: https://arxiv.org/ftp/arxiv/papers/2307/2307.12037.pdf Would love 3rd party confirmation as well, of course. Edit: Here's a video! https://www.youtube.com/watch?v=EtVjGWpbE7k
Thanks, I was looking for that video that was referenced in https://arxiv.org/ftp/arxiv/papers/2307/2307.12037.pdf
It's unlisted as well but published back in January of 2023. I wonder what they are going to think with the influx of views on it, (43 views as of this post)
Is it just me or is it odd not seeing the normal condensation of the surrounding air due to a chilled superconductor like you get with a YBCO.
Re: The first room-temperature ambient-pressure superconductor?
#170I see lots of comments saying this is a huge deal if true. Can I ask... well, why? What can we do/make with this?
https://en.m.wikipedia.org/wiki/Superconducting_magnetic_ene... Basically really high density batteries that work efficiently forever, zero friction bearings via levitation, zero resistance long haul energy transport, and an MRI you can probably run on household current. Plus maximally efficient (not perfect efficiency just the best we could theoretically practically get) energy storage, transport, generation, and co…
Wow, that really does make it sound like a potentially world-rocking discovery! (if it turns out to actually work in reality, of course).
