What is this, a superconductor magnetic levitation train for ants?
SteelMakesMeHard
Quantum locking is pretty fantastic
griffin4cats
That's not the coolest part IMO. You can move it around, position it. Even flip the track upside down and it still works.

These are cool for like 2 sec until u realize the amount of material and energy needed to make this scalable.

"Train"?

For anyone wondering, the way a magnet floats over a superconductor is known as the Meissner Effect.
Ipostdoges
So due to inertia and a near complete lack of friction this thing should go on for a very long time. Only air particles will slow it down?

Warning: secondhand Superconductor Magnetic Levitation Train smoke is just as deadly as Superconductor Magnetic Levitation Train smoke!!
DavidBrooker
Its water condensing / crystallizing out of the air.
ThatsPermanent
So it's exactly as deadly as any other water condensing / crystallizing out of the air! Good to know.

But won't we need giants to push the normal-sized trains?

Just begs the question: how does one stop such a train?

That is not what "begging the question" is.

To "beg the question" is to assume the very thing you are trying to prove in an argument. I'll show myself out.

Drop a wheel, brake as usual.

Also the same magnetic forces that propel it forward (a finger push is used here, without a push it would hover) can be used to slow down.

heat it up... it's only 'frictionless' when super chilled with liquid nitro
Drunkeroc
That won't be expensive.
ErinFromTheOffice
MilDravin
well, it is a magnet of sorts, that's why it levitates. quick n simple:: the super chill keeps the mag field from flipping it etc etc
RamAssScratcher
The track is a magnet the superconductor is the object. You can see the same effect witha magnet dropped through a copper tube 1/2
RamAssScratcher
However since copper is not a super conductor the magnet falls through but at a much decreased rate the maths behind is really cool 2/2
Apeofdeath
Japan's bullet trains ride on magnets
FiftyShadesOfCauliflower
There's also China's German-built Transrapid train. Developed back in the 1960s, ate lots of tax money. Now the only line is in Shanghai
FiftyShadesOfCauliflower
Turns out it's way too costly to operate. Regular German ICE high-speed trains are almost as fast and much cheaper
DavidBrooker
Not the ones in service, those run on standard rail. But their developmental maglev trains do, yes.
GeorgeHWBushsGhost
But they aren't superconducting. Making it superconducting would change it all.
implodingrat
how so?
GeorgeHWBushsGhost
As another user said, they are still on rail, but by making them maglevs it removes the friction that would be present on a track and ->
GeorgeHWBushsGhost
<-allows the train to go much faster as a consequense.
DavidBrooker
How does that differentiate between electrodynamic and electromagnetic systems? That's just conventional versus maglev.
GeorgeHWBushsGhost
Well, electrodynamic systems are the electromagnetic suspension systems used on maglevs.
DavidBrooker
That is patently false. Japan's current maglev designs are superconducting, this is easily verified by a cursory Google search.

GeorgeHWBushsGhost
In both sources you provided it states that the superconducting train is a test train.
DavidBrooker
Of course they are. The only maglev trains Japan has ever operated have all been test trains. Talking about Japanese maglev trains 1/2
DavidBrooker
explicitly means you're talking about full-scale engineering test articles. They've all been superconducting since 1994. 2/2
Ecne
when we will make superconductor that will work in normal temperature.. then it will be awesome
oyoyoyyyyy
There was a paper on arXiv on "373K superconductors". Never really panned out...
LucienTheLuckless
Awesome except for the genicide of the Navi people.
TonyBalogna
Just freeze train down to absolute zero. I don't see what the problem is. People will just have to bundle up.

Earlier this year Harvard researchers claimed to have created metallic hydrogen which may open the possibility of such a thing
pwnscon3
They were saying it was useful as a solid rocket fuel, but no mention of superconducting qualities from what I heard
TheBlueGenie
That's the claim. But the diamonds were coated with aluminum oxide to harden the diamonds under of pressure. More conclusions needed
Malus1n1
And then they lost it!
Tehsyr
It evaporated.
DontBeSheep
I like to think the Russians stole it
DorthLous
Sublimed, rather. No liquid transition.
Hepwolfx
No they literally just lost it. Metallic hydrogen is predicted to be meta-stable. Meaning it will stay solid once created.
ThoseSheepAreFareAway
Ahhh yes using Hydrogen for transport. Super safe
ByThePowerOfSCIENCE
It depends on how much you need to stay off the tracks - the difficulty is keeping it at tens of gigapascals.
puddin151
hydrogen is only slightly more dangerous than gasoline, it still needs a spark to ignite
ScootyPuffSr
Did you drive today? Then you burned hydrogen for transport. It was just tied to a bunch of carbon to keep it safe.
ByThePowerOfSCIENCE
What relevance does it have regarding safety? Carrying NaCl is nowhere near the same as carrying Na and Cl.
ByThePowerOfSCIENCE
That's like saying I had sodium, calcium and chlorine for breakfast.
