New claim of room temperature super conductor has been made. LK-99

I worked on superconductors in the 60's. 8 degrees absolute was the best we had. ~80 degrees absolute today impresses me. Don't expect room temperature this century.

My husband started watching this but then he got SHOCKED and I had to call the wambulance. Be careful out there!

Maybe the turbo pump designs in rocket engines can benefit from superconducting electric motors when they can be cooled by the cryogenic fuel?

Will it fit in my 96 Honda Civic?

At 1:28 Isn't that a CT scanner? You can see the detector array at the bottom (5 fans) and the x-ray tube at the top left

Interesting Video, THX subbed 👍

conventional motors also quite effective (especially on such power) but of course way heavier. but cooling hardware also have weight so not everything are clear.

Big questions... Is it reliable under arduous conditions? Is it's cost within the reach the average consumer? Is it sustainable?

Must have massive torque!

Would be good for a generator rather than a motor. The mechanical to electrical conversion would be over 95%

I did not know about it. But very high conductivity could mean that the skin-depth with a varing external magnetic field is much smaller. This would increase the inner current density inside the super-conductor and decrease the total rotating current capability. I did not read much about skin-effect in super-condutors, it seams they are for static fields.

I theorize that with magnetic bearings and magnetic gears we could achieve over 100% efficiency.

The torque potential could destroy the smaller lighter motor when full power potential is applied. ( i.e. due to its lower mass relative to input power ) it would have to be optimised to function within the operational limits of the motor, due to material strength limitations. I guess they've done all that testing, so they know it can work.

nice to see other uses than levitating a magnet. Also 99%efficiencies have been achieved by commercial electric motors long time ago, it's only unheard of by people who don't follow tech.

At anywhere near ~20T, steel cores would be pointless, as they saturate ~1.5T. Additionally, steel would have enormous core losses at ~20T. What do they use? Air cores now?

Sounds encouraging if they can raise the superconducting temp.

Even if this motor is 99% efficient, at 2 MW power output one still needs to remove 20 kW of heat to keep it at the same temperature. That sounds difficult to achieve. But hey, engineers...

FYI, some lower tesla MRI's use permanent magnets.

Imagine the intensity of a staredown between an ICE driver waiting for his motor to warm up and an superconducting EV driver waiting for his motor to chill

I am not shocked. What industry was shocked by this well-known, decades old development?

I don't see where boosting a motor's efficiency another 10% will ever be cost/power effective when cryo equipment must be used to do the cooling. Any size improvements are immediately lost as well.

so esxciting... cheers!

I have worked with a ceramic-type superconductor applied in a dispositive to limit an induction motor starting current. It is incredibly challenging working with these materials. Finding a superconductor material at room temperature and/or developing a manufacturing process for mass production with high-quality levels will be a turning point in society. It will powerfully increase efficiency in energy production, transportation, and computation.

Oddly enough, the motor is not crazy and it didn't shock the entire industry.

One possible use of this. Use high voltage DC for transmission and using the dc to turn this motor generate AC for cities.

What magnetic material can conduit 20T flux?

Room temperatures are not needed for this to be useful. Motors usually already have active cooling systems, so we just need a colder one. The losses and hassle from this cooling will only be offset by the gains in power, materials, and efficiency in very powerful systems. So this would be very unlikely for daily passenger cars. High temperatures in this case means liquid nitrogen. Liquid nitrogen isn't cheap or easy to work with, but neither is jet fuel or steam. Its the classic trade-off : do I just put in a bigger engine, or do I add a turbo and a bottle of NOS? I can imagine racers topping off their nitrogen tank at the welding store just like they do now.

This happens when a perpetual motion machine spins so fast or something

What usage would a motor of these specs best suit?

Shockingly shocking shocker

So a 400, or 800lb motor, with 10, or 20 tons of batteries, copper, and cooling equipment, to run it. Genius.... I'm guessing large scale gas turbines, or diesel gennys at the airports to charge the mega ampere batteries?

How much more powerful is superconducting motor compared to the same size non-superconducting motor?

99% efficiency isn't "unheard of" (04:10) - it can be achieved with conventional copper and clever motor designs.

Considering that there is a finite amount of helium I don't see how this could be sustained if it is required. Liquid nitrogen is not cheap either. 2666 hp would be pretty sweet though.

Rochester, Reddmatter, 20.9 degrees Celsius. Near room temperature superconductors… but I doubt Toshiba is using this, there’s a lot of development required.

Make a video on quantum generator patent...

Does it heat up when under heavy load? Seems cumbersome.

Cool.....

If its a motor its also a generator. I think Rolls Royce was working on something like this driven by a turbine to produce around 2-3MW of electric power for longer duration eVTOL aircraft.

Interesting. Early. Days for this

"helium, which is a lot more plentiful... well, at least on Earth" wtf? what planets have you been to?

Power plant can use this concept to generate electricity 10 times more in same space

Peculiar...

"an over hyped," not "a over hyped."

Have I been misinformed? I thought graphene can superconduct at room temperature.

Probably not going to be in a car unless high temperature superconductors manage to be found.

Megawatt scale electric motors using superconducting coils are not a new thing. The US navy has been chasing this for decades to the purpose of electrifying its destroyer fleet and increasing its efficiency.

How do electric motors gain torque? More current or more coils or something else?

I think it has insane military use. On a missele per chance? Just load it up with liquid helium in a tank. Give it autogenous pressure and boom! Literally. It just has to keep the thing cool long enough. Maybe I'm just not being creative enough but until the technology matures significantly I don't see a lot of civilian uses.

I thought it was a bicycle motor ;-)

Awesome video, induction motors are better than BLDC motors because induction motors requires less fancy sensors and chips they to change poles with AC current plus there's no risk of demagnetising the permanent magnets, copper windings on steel core are best.

So, I had an idea about how cool it would be to have the opposite of a microwave beam. Heh, I said "Cool' idea", because that's what it would do. to COOL , rather to radiate. Almost timing the radiation to radiate against the materials natural vibration. If you are reading this and can achieve this idea, DO IT. Design it and get it done.

Toshiba is going broke, and getting sold...They still have some assets or is it PR?

Few hundred kilos!? That's basically a truck engine but 5-6 times more powerful!

Probably pulse tube cooled

The wires are super conducting so they don't lose part of the electric energy in heat. But how do we keep the environment heat reaching the wires? Simple we cool it with super cold helium. But how do we take out the heat from the helium to trow it back to the environment? Easy we use very energy inneficient cooling systems like a refrigerator. So what happens to the total energy we use to make the whole system work? It's not in the paper. Everytime I hear about new breaking ground technology that don't mention the overall energy efficiency of the whole system, I know it's a marketing scheme looking for 'free money' to finance the R$D of some project. This has been going on for decades with the nuclear fusion (potential) industry.

prob marketing, see some real footage of it working 1st

I've developed a distinct🤬 dislike for these things that 'SHOCKS Entire Industry'. I nearly blocked the channel for that. If I didn't also like actual information that I can make sense of...

liquid helium cooled ac motor, that compresses and pumps liquid helium.

cooling gas gens is good model reminds on airplane engine and nuclear salt reactor type cooling weight lose is ok if price in production large is resumble what if air turbine air cooler aditionaly added on gens like tesla has this part such as eficent airstream airgliding acc to swuush electric sound and then is even faster and air cooled and nitrogen too

0 I'm sure it works,, but that's in a lab....no money was spared for a one off ,,very clean cut electric motor..that makes your jaw drop..NOW..the problem is ..to the masses = very expensive..to scale down all that wonderful cooling system from a room/lab into a tight compact car/train/plane/boat = very expensive..safety in those mediums- test after test years after years = expensive and a little to late..I'm sure the real science is [ NEED IS NOW - and that the masses can afford such a great motor ..and the safety box is ticked ] ya goofy m8te from Australia

I think this motor could be very useful as a thrust drive, for changing direction of space craft, or even powering it.

Elon Musk was here. He is now calling TOSHIBA 🇯🇵

"A over-hyped..."? AN over-hyped??? Skipped Fifth Grade?

I think I am unqualified to speak on this topic ;-)

At 01:58 - How does one cool something to an extreme temperature? I think he meant to say 'extremely low' temperature. I'm no physicist, so who am I to argue.

Not impressed. Even a puny Tesla motor has higher specific power than this. 1/4th of the power but in 35-40 kg? It seems the cooling of this motor requires a lot of hardware.

now, this title made me unsubscribe.....

A waste of time, axial electric motors are superior to radial ones, a priori
