MAGNET MAGIC / SUPER CONDUCTORS

[Peterwhitlock]

Ok

so in space this stuff can make non contact machine parts?

Never wear or tear stuff?

what applications has Humanity come up with for this in cold space? i can't find any!

[ManijakTotalni]

Fucking magnets...

[ricosauve08]

i bet the answer to perpetual motion is somewhere in the understanding of that because if it were in a vacum it technicaly should just keep spinning because there is no friction. it makes you wonder what else is out there that we havent figured out yet. science is awesome and confusing.

[improductive]

when things get soo cold they turn to a super conductor... electricity can pass through it without loosing electricity

[mygaffer]

Wow, what an awesome technology. Do they have to be so cold to work though? Imagine the things you could do with that technology if you don't have to keep it super cold. I would get a levitating bed to sleep in.

[alihaggis78]

Unfortunately they do have to be that cold at the moment. This is actually what would be termed a high temperature superconductor. The first generations of superconductors had to be cooled with liquid helium which is much colder. Reserch is still continuing to find new superconductors that will work at even higher temps with hopes of producing one that will work at room temp.

As for your levitating bed I'm affraid you'd have to be magnetised to float above a superconducting mattress.

[allblack456]

that would be awesome to have a huge one of these in ur house

[Nemisis906]

God is an amazing man...

[5859987]

that thing stick like glue , then can it fly??????

[Darkslither]

real life hackers ... damn noclip phys objects

[ryusassori15]

lol'd at comment.. (im a Garry'smod veteran XD)

[UberTroll13]

hax lol

[F4ntomDimitris]

science is just really fascinating!!!!!

[sethdavid1997]

thats science for you

[ilove3dcomics]

that was cool!

[098green098]

thats so kool

you used the liquid nitrogen ans the super conductor with a magnet

smart

[mrwideboy]

it works by lens law of magnetoc induction "An induced electromotive force generates a current that induces a counter magnetic field that opposes the magnetic field generating the current."

Also by the meissner effect of superconductors which expells the magnetic field from the superconductor

[pmarceau]

The levitation I understand, what boggles me is the dual force. Not only is the magnet held up by the SC, but the magnet also pulls enough to hold up the SC.

Could the magnet hold up the SC the whole time, or is it a transitional period as it warms?

[mrwideboy]

it works by lens law of magnetoc induction "An induced electromotive force generates a current that induces a counter magnetic field that opposes the magnetic field generating the current."

Also by the meissner effect of superconductors which expells the magnetic field from the superconductor above Tc. This was solved by the london equations.

[jamieball]

There is something really magical about magnets and the magnetic properties of our solar system! :D

[Nirdian]

faKE?

[brucegray666]

No, science.

[roadtorandomness]

this was on oops tv lol

[addiecody]

this is what interests me.this is really fascinating

[cuneyyyyy]

You can not even reach the absolute zero it is laws of thermodynamics. you can get close to it, it's 0 Kelvin, closest they've got was (1×10−10K)

[eddahahaha]

science is really cool

[yellowrox12]

awesome....

[snowyyyyyyyy]

awesome omg

[animalresercher]

teach us how!

[miztahfrawg]

yowzerz.

[DeathXLight28]

that kind of gas cause too much right..?? and it must be cooled below absolute zero

[brucegray666]

Don't know about the cost of it but I do know that it impossible to cool anything below absolute zero - it just cant be done!

[esdlive]

actually that's why there are different medition parameters...

in centigrees, de 0º actually represents the point that at normal conditions the wather turns into ice... the absolute zero is the farenheit 0.. and thats when all molecules stop moving.. sort of -127º (something like that... google it)

[brucegray666]

Asolute zero is 0 degrees KELVIN, not farenheight. It's the equivalent of -273 degrees C.

[firehawk97]

Yes... and why people are saying that you can cool matter below absolute zero is baffling me as much as it is you! It's called Absolute Zero for a reason... I suppose people don't get that. So what metal did you use in the videon anyway? Or was it an alloy

[slipknot3daysgrace]

yeah, they are bullshitting. when matter reaches 0 kelvin, there is absolutely no thermal energy in the substance, and an object is cooled by taking out thermal energy, sooo...it can't be cooled...cuz theres no thermal energy.

[firebug12690]

I know they say we can't reach absolute zero on earth because the material is always touching something so some heat is always transferred, but what about in space? Where stuff floats (or falls, however you want to say it) and doesn't need to be touching something?

[Tamalain]

@brucegray666 Niquid Nitrogen is much warmer than LOX , LHe, or LH. It cost less to produce and tends to stay colder longer than most gasses. Still, to use it large scale, the power cost outway the benifits you might get from the SC currently in use. We need to get Conduvters up to dry Ice temps before they would be effective in a commercial use.

[btmonson]

@DeathXLight28

It's not the cost of the gas, it's the cost of cooling it. Researchers have blown millions trying to achieve absolute zero and have gotten close, but not quite there. It is theoretically impossible to achieve true absolute zero. The only way to do it would be to shield off every bit ofthe heat from the rest of the universe with a perfect insulator. Of coarse, in our world, perfection does not exist.

[GAspieler]

@DeathXLight28

it is liquid nitrogen and it costs less than 10$ / liter.

[Siruiel]

see how slowly it landed, wow :)

[MrFairygodmother]

so... It looks like the kinetics just stop when that superconducting thing is super cooled... cooool....

[hydrogenman15]

Brain wave!! While sc's only work a very low temperature's , they still can have super insulaters and if a magnet can be suspended in a vaccium you could spin it at a very high velocity. Which could hold a lot of energy.

[brucegray666]

however.... wouldnt you need to put a lot of energy in to maintain the vacuum??? i see your thinking tho.
