Gutes Video! Aber sprich bitte nicht so schnell. Dein Englisch ist schwer zu verstehen, wegen dem starken deutschen Akzent. z.B "cushion" wird "kuschen" ausgesprochen.

Super conductors have a dirty secret: There is a maximum voltage you are allowed to apply or the Cooper-pairs break apart and it becomes resistant again; usually more resistant than copper. AC then causes energy to leak between the cables more than traditional onces, because they are closer and therefore have greater capacitance.

Let me advertise my new innovation 'Iron lift light'. It replaced magnetic lifts with steel weels. This dramatically reduces friction and makes it allot cheaper.

the ones in Japan do like 500km/h

How do you brake?

I have a sonic toothbrush with Maglev motor and i kid you not, it only has to be charged every 1-3 months depending on how intense the use is 🤙🏼🗿

Very good video😊

Vielen Dank fur diese Expose von ein andere Gadgetbahn. Our rulers are so rich that too many engineers are pitching stupid ideas to even stupider greedy people... because existing railways either can't or don't want to spend money to hire engineers for projects that would really expand range and frequency. Railways go where roads go more cheaply, with less maintenance, pollution and injury. If we built more tracks to take more traffic and service more businesses directly, then rail would also move more people and stuff faster. Yes, trucks can handle steeper grades, but most trucks aren't driving up and down mountain passes. Our world does just fine with steel, copper and aluminum to move us around.

I wonder if this can magnetize the rails, and if it only works on welded track.

I've watch this twice and I don't see where the lifting force for the vehicle? The magnets affect sideways forces but nothing is proving the lift above the rail. So what I'm I missing?

The best area to concentrate research here is better insulation. You have to reduce those cooling costs and infrastructure requirements as much as possible. But if we keep getting better cables, I wonder if it will be possible to (eventually) implement a world-wide grid of DC transmission cables primarily relying on solar panels covering the Sahara, Australian outback, and North American desert.

It can't work, this is literally how emergency brakes of ICE trains work. I just don't understand how can they pull this stunt for so long.

That would be awesome if it can keep its promises

10:25 Wait!??? So not only, is a continuous flow of liquid nitrogen needed, and probably some kind of venting system for the nitrogen that gets too got & boils off?... You ALSO in this case, need basically a 1.5 Km long HYPERLOOP vacuum tunnel... filled with the inner liquid hydrogen cable (with venting systems)??? Yeah... nah, I don't see how this would become successful in a large scale power-grid. (12:00 Yeah... that's just one of the problems)

5:03 *Does this mean that the cable transports TWICE as many electrons ("per electron"* normally transferred?*) (*Eg. instead of moving 1 electron at a time, now it moves 2 electrons in a pair instead?) Also, because the 2 electrons form a Boson, does that mean they can't spark like electricity normally does? Does "boson arcing" exist?

“China says” -Lying Chinese Government Officials-

Imagine a big super conducting cable going all around the world, and Solar power feeding all around the clock....

Can't say I'm a fan of using cryogenic superconductors for carrying extremely high power over long distances: you are only one refrigerant leak or refill failure away from a very expensive catastrophic failure. Once you have HVDC, you can use arbitrarily thick conductor cross-sections in whatever material is most cost-effective to accommodate higher current at reduced losses.

Don't say ,activate die Bell ' 😆

I checked it out and it’s still off-line and does not work at all. I cannot connect to it or do anything with it.

Sounds nice. Competition is good for the consumer.

Nope, still to expensive mainly due secondary infra needed. Same as why planes can compete with trains on both time and total costs of that railroad infra even at relative short 100~500km runs.

Imagine a leak and it would take weeks to fix during war time. Just increase the thickness of the cables instead. Much simpler and easy to repair.

I mean, honestly, it sounds really cool that they designed a generator that seems to be exactly the same thing an old english bloke designed and put on youtube about 2 decades ago... I mean, it sounds like they upped the operating pressure and therefore the frequency beyond audible, but yeah... It sounds like they managed to copy a (very smart) old bloke off youtube; kzbin.info/www/bejne/qGnIinx9f6yYnKM&ab_channel=barumman

i wonder what would happen if someone were to cut the cable where the coolant resides (one of the outside layers) while digging somewhere, i guess you would have a every expensive normal cable.

Iirc Cooper Pairs only work for low temperature superconductors. Besides that: Since the video of Veritasium I am still confused about how electrons actually transport chsrge through a cable…

Is this why 2 of their submarines sank & lots crewmates?

SWM, alles klar, Stromtarif basierend auf purer Wasserkraft, so grün! Und plötzlich über 60 Cent pro kWh! Weil ... naja ... aus Gründen! Verlogener Saftladen.

The cable between the Iberian Peninsula and the Balearic islands could make a good use of those!!

Great explanations of complex topics and I certainly learned a lot.

I'd expect a channel that declares itself to be about science to bring also some scientific and techincal details. Having all those references is nice but really, the video is just advertisement of the project and all information given could be condensed to two paragraphs, the only reason it is so long is because we get to hear them over and over again.

Interesting, well presented in excellent English. Please check 'blatant' however, It is only used with a negative connotation.

I hope it can be viable for thousands of km in the future

Aren't there a couple commercial cables already working?

Aber haben nicht auch andere nach Silber geschürft ?!

When profit is the main driver progress is too expensive and the environment suffers Utilities should be government owned

Why 150 m of a superconductor cable is a world record when the Holbrook Project with its 600 m long cable is in operation since 2008?

As a Canadian, I am looking forward to when it can be scaled up a lot. Hydro-Quebec's James Bay transmission lines carry over 2000 megawatts (MW) of power more than 1000 km at 735 kV. The savings will be significant when we can start using them to replace high-voltage lines.

But here is the important question: between a traditional latge footprint transformer station and a superconducting one that wlso needs to supply liquid nitrogen, which one is quicker to repair after it got hit by a cruise missile?

You can probably recover much of the cooling energy. Liquid nitrogen expands 700x when it turns to gas, so any boil off could be used to spin a turbine or to cool a supercritical CO2 cycle which would benefit from wide temperature difference between n2o and ambient temperature

Moin! Gibt's eine parallele, deutsche Episode dazu? Inchidentally: Servus from Munich!

also wieder wieder eine Technologie wie der Transrapid Zug. schön das es in Deutschland entwickelt wurde aber vermutlich geht es wieder über ein Pilot Projekt nicht hinaus und andere wie China werden Geld rein pumpen um uns in dieser Technik ab hängen. 🎭

Bei "mein Name ist Dr. Jakob ..." hat er mich verloren. Wenn er immer noch glaubt, dass "Dr." ein Namensbestandteil ist, hat er es wohl nötig. Sorry guys, that was some typical German nitpicking by me.

As a retired Californian, I follow such developments as this in the hope that eventually long distance superconducting cable systems can be built in trenches through our fire prone forests to replace the problematic power transmission towers. Had such system been installed in Altadena to go over (or through) the San Gabriel mountain range, high winds would not have been an issue and one of the fatal massive fires we have been suffering would have been avoided. The system you describe, with appropriate automation for liquid nitrogen support should eventually serve these relatively short energy transmission links as well as the ones in major cities.

Sorry this is just bullshit. Why do you even present such nonsense as tech news and give it a stage? Superconductors have many useful special applications - power cables are not among them. Power loss on power cables is already minimized by stepping up to very high voltage. A cheap stainless steel cable will do the job. Meanwhile for fancy superconducting wires you need... very expensive superconductors and liquid nitrogen cooling which needs an extra LN2 facility and consumes a lot of power. That cooling is way more power loss than traditional cables. Makes neither sense to build and nor sense to keep in operation.
