Im posting this reply from my mainstream smartphone: a pocket supercomputer with a 4K 60Hz HDR video camera. I’m chock full of designer vaccines and can watch a catalog of almost all the movies ever made on demand tonight. I listened to an podcast in my EV on the way to work. And SpaceX probably launched 60 satellites this week on the 14th flight of a rocket that flew home afterwards. Things have been moving along. e…

>can watch a catalog of almost all the movies ever made on demand tonight. You must have one hell of a different streaming services experience from that of most people today if you can pull this off without engaging in a fair bit of torrenting and general piracy.

No you just decide what movie you want to watch and pay $4 to rent it on demand. Very common experience available to anyone with a smart TV or connected streaming device.

On a completely different front, let's say the paper completely checks out and they have discovered this miracle. How strong are the patent protections on materials science? For example, if someone could replicate the effect with lead + gold, would that be considered a novel material which would not be subject to licensing? Is it the material itself or the method of production?

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

The worst possible outcome of weak protection is not creating new materials.

I feel like the host of “in 30 years we would have X” made 40 years ago are suddenly manifesting.

Important correction… the catalog of movies is likely significantly smaller than all the movies ever made… the ongoing removal of new movies for business reasons and the market fragmentation mean that reduced profits are leading to corner cutting with respect to the size of stream catalogs, licenses cost money… pirating via torrents while larger also has diminishing returns as you step outside the mainstream movies, unless your lucky and find someone diligently sharing bandwidth to keep content online happens to share an interest in that niche… we’re rapidly losing access to an entire generation of analog only media as people throw source material into the trash and corporate stewardship of original recordings slowly fails one papercut at a time for the decades it will take for work to enter the public domain and be properly archived by the people trying to hold onto all of this.

We could have maglev trains and superconducting supercomputers and copyright will still be deleting our culture to “save money” for corporate copyright owners to increase their profit margins.

It’s a breath of fresh air reading about actual revolutionary science happening. The deluge of news about non-replicable results, fabricated data, overhyped press releases from both academia and industry had become really depressing. For once after a long time it’s the real deal. Even if this is not a RT superconductor, it’s now evident that the original authors didn’t cheat and are not crackpots as initially suspect…

What is interesting is that assuming it all pans out these are all in entirely unrelated fields. That sets the stage for a whole raft of follow on inventions. Similar to how the telephone + basic electromagnetism led to radio, tv, radar, transistors and ultimately to computers small enough to be practical for businesses, the internet, cell phones and so on. My grandmother was born in a house without running water, no…

It's exactly like we got one critical item in the tech tree of humanity taken care of.

Technology trees are fascinating, how much sometimes hinges on one tiny invention.

I believe there’s no way to stably suspend an object on permanent magnetic fields, so if this is stable and doesn’t fall down then it’s hard to argue superconductivity isn’t involved.

There are diamagnetic non-superconductors like pyrolytic graphite that can also evade Earnshaw's theorem, but this would be the first metal with this strength of diamagnetism at room temperature AFAIK.

Pyrolitic graphite can evade Earnshaw's theorem only with either specific magnet array shapes or with rotation, they still can't stably levitate on a regular dipole without rotation.

From what little I understand the levitation effect doesn’t necessarily equal all the properties of a superconductor. It’s one of them though.

Are other forms of diamagnetism temperature dependat? Because this one is.

Yes, there exist diamagnetism-paramagnetism phase transitions.

Why are folks trying to prove that this material is a superconductor in roundabout ways, like levitation, dimagnetism, etc? What is the reason they don't just test to see if electrical current flows without resistance? Surely there is something I am missing here.

How would you prove there isn't any water in a cup?

I didn't see any references to cups or water in these papers.

I'm not too familiar with this space. Could someone explain how big of an impact to the world this discovery is? What does the future of this technology look like over the next 5 years?

If true, five years not that much difference. A few decades, large differences.
