What does it mean? More efficiency? No heat generated?

[–] There1snospoon7491@lemmy.world 44 points 1 year ago (1 children)

Iirc (and as an extreme novice) superconductors allow for transfer of incredible amounts of energy with little to no loss, but require extreme supercooling to do so. A superconductor that doesn’t need that cooling would allow super-efficient energy transfer with very little to no cooling needed, meaning the overhead costs are reduced dramatically.

This would be a wonder technology if proven to be true, but my understanding is most of the rest of the world is highly skeptical at the moment. It’s like having your cake and eating it too.

I’d say it’s more like simulating the best tasting cake ever in a computer, then telling everyone else to go bake it.

Hopefully someone can figure out a process to create the material in real life (then hopefully it’s durable and eventually economical to produce).

Afaik they did build it in real life, and the paper in fact is about the process for manufacturing it, not just about the properties or simulations.

People have replicated the simulations so far, but are still working on replicating the manufacturing process, as it has low yeild and some variability apparently

[–] Maximilious@kbin.social 4 points 1 year ago (1 children)

The problem with that paper as I understand it is that the writer was recently outed for making many false claims in his research.

[–] aebrer@kbin.social 4 points 1 year ago

Interesting I hadn't seen that. Do you have a source I could check out? There's six authors so it'd help figure out what you're referring to

[–] tsz@lemmy.world 24 points 1 year ago (1 children)

Most scifi movie things you can think of would be on the table.

[–] clgoh@lemmy.world 6 points 1 year ago* (last edited 1 year ago) (2 children)

Warp drive?

Artificial gravity?

Time travel?

[–] aebrer@kbin.social 5 points 1 year ago* (last edited 1 year ago) (2 children)

Maybe (or at least an albecuire drive)

Maybe

Probably not

Also some more "basic" things like cheap MRI without requiring helium (which we are running out of), cheap and easy magnetic levitation (more available high-speed trains)

[–] SkybreakerEngineer@lemmy.world 6 points 1 year ago (1 children)

Last I checked, alcubierre drive still requires negative mass, which is not a thing. Time travel and artificial gravity are still theoretically impossible.

[–] aebrer@kbin.social 3 points 1 year ago

Yeah artificial gravity I was thinking more along the lines of faking it via magnetism.

Albecuire drive I was just wrong about, you're right it's not a maybe it's a nearly 100% no lol.

Sorry just excited.

[–] WarmSoda@lemm.ee 1 points 1 year ago

Albecuire drive is basically science fiction. If it's actually possible we won't be seeing it any time soon unless we find a crashed ship on Mars or something.

[–] cassetti@kbin.social 18 points 1 year ago (2 children)

Yep. You know how hot your phone gets when charging? Or how hot a playstation gets when gaming for hours at a time?

That's due to heat-loss generated by the circuits. Superconductors would allow them to run much cooler generating essentially zero heat. Which means they can run more efficiently or faster without the need for larger heatsinks or complicated expensive cooling systems.

[–] Mrduckrocks@lemmy.world 2 points 1 year ago

This is huge if true.

[–] asdfasdfasdf@lemmy.world 17 points 1 year ago

Way more efficiency, almost no heat generated. Quantum computers in your pocket. No need for fans in computers anymore, even for supercomputers. Way more efficiency at sending electricity long distances. Things like maglev trains and fusion reactors and MRI machines can use superconductors without needing to keep the temp at negative 450 F. Cheap MRIs mean accessible, inexpensive MRIs for all. The list goes on and on.

[–] orca@orcas.enjoying.yachts 15 points 1 year ago
  • Much less heat output
  • Much less power usage because the components traditionally used to cool are not required (which makes it much cheaper to run)
  • Lossless power transfer which is much more efficient

[–] Djeikup@lemmy.world 8 points 1 year ago

Yes, because less heat. So we can crank it higher with no drawbacks. (Simplified reasoning I dont know a lot about circuit boards)
