Long-distance energy transfer without energy loss will make it possible to connect more energy grids and sources together, so stuff like the saharan desert providing solar power to Europe, for example, suddenly becomes feasible. Maglev trains will no longer require lots of power to run, since they could utilize superconductor magnetic levitation. You could make super-efficient processors that wouldn’t really heat up at all. Superconductors are also key to quantum computers, so expect lots of advancements in that field as well. They will also make it much easier to build and run fusion power experiments.
Lots of tech in general would benefit from this discovery, stuff like MRIs, electric vehicles, space telescopes or particle accelerators would become way more efficient, cheaper and easier to produce.
Not really. If that turns out to be true (nothing is guaranteed yet), the processes described are pretty straightforward and don’t require any super-advanced tech to be reproduced. Full-scale production could be rolled out in mere years. That would become beneficial for stuff like MRIs or electric cars as soon as production starts.
After that, my guess would be that some large-scale energy infrastructure projects, for example, could be completed in about a decade.
Does this get us hovering without rails? Could we theoretically generate a magnetic field strong enough to repulse the earth? Or is that still Science Fiction?
You still need a magnet-superconductor pair for quantum locking and magnetic levitation. This is called the Meissner effect and it seems like it has been confirmed for this material. Here’s a video showing an example of such a system.
Before, the best way to scale this up might’ve been to make permanent magnet rails and run a superconductor train along those rails, but that would have been totally infeasible and inapplicable in real life, since building rails out of permanent magnets is expensive and dangerous, and the train would need to house a really large superconductor chilled to liquid nitrogen temperatures. You couldn’t have built a track out of superconductors irl because good luck keeping those at the temperatures required for superconductivity to kick in.
If this material turns out to actually work as claimed and to be producible at scale, you can switch those and make an electromagnetic train that travels along superconductor tracks. Which is way easier, cheaper and much more doable in general.
But the earth’s magnetic field is extremely weak, and even the tiniest pieces of superconductors are unable to lock with it. So no, it does not allow for trackless levitation.
But a cool new train system design becomes possible though!
You’re right, haven’t heard about that one. They actually do use superconducting magnets on a train that runs along a magnetic track.
But I feel like my feasibility comment still stands. It seems like all they had built is a 18km test track, and there’s some info about extending it to 48 km, but it doesn’t seem like the extended part uses superconducting tech yet, it only mentions regular maglev. The Tokyo — Osaka line is planned for 2037. So yeah, its technically possible, but it’s not like you can cover Europe or the US with this type of track for any sensible amount of money.
That’s the cool part about room temperature superconductors, they make this type of tech possible on much larger scales.
I’m most excited for fusion power generation. Currently we can ignite a fusion reaction but it takes more energy to control and contain it than you get back because it takes a huge amount of electricity to generate a magnetic field strong enough to contain the plasma. The strength of the magnetic field is proportional to the current flow, which is limited by how much cooling is required to maintain superconductivity. Without cooling taking a huge chunk of the power created by the fusion reaction we could net positive energy from the reaction and finally have a clean source of scalable nuclear power.
If they can be made into wires (or close to them) you can create things like lossless electricity transmission, lossless batteries, electronics without heat generation (or very low), etc. Transmission lines would likely still need some sort of cooling but at room temp it would be a lot less than for the current superconductors that require at least liquid nitrogen.

God damn this sounds exciting… But also like 100 years away 🙁

I hope you are right

Superconducter maglevs are feasible and have been in service for years. They are building a large line in Japan.

Yeah it is really neat. Especially since we are ostensibly close to net positive energy in some of the experimental reactors already.

I’m not entirely sure about the practical applications, but my gut feeling tells my it’s hella cool.
USB-D
No. Just no. C is good enough. I’m not buying anymore fucking cables.
Well for one, we’re running out of helium and fast. Helium is used to super cool existing superconductors, like those used in MRI machines.
And then there’s the power transmission benefits. Right now we’re wasting upwards of 50% of the electricity we generate.
What do you mean by wasting if it’s referring to transmission losses that’s closer to 3-6% not 50%
Ah hell I meant to type 5% and actually typed 50. I got that number here: https://www.eia.gov/tools/faqs/faq.php?id=105&t=3
Ok fair enough
floatation devices? I would like to know as well.
