Magnetic Wheel on top of Liquid Nitrogen

[GumokCZ]

it's not nitrogen, it's burning :)

[alphakid42]

He picks up liquid nitrogen? Ain't it very cold?

[MrConundrum2020]

it's magic... ooooooooh.... science is like magic.

[shredb79]

powerful looking forearms makes it look like he snaps kids' necks for a living

[blanknot]

My school can't afford magnets and liquid nitrogen, but they can afford brand new uniforms and training equipment for the football team.

[Grundalizer]

@blanknot But football players help to create some of countries most important technologies and are a much better investment than our future scientists and engineers

[MonteLSV6]

That's fucking sick. You can always count on the Japs to make some futuristic technology.

[luc59457]

Make it electric!

[luc59457]

The magnetron doesn't float because they put liquid nitrogen through the rails LMAO! That would take way too much and simply not practical! The Magnetron works with Electromagnetism. You have coil on one end (the rail) and magnets under the train. Once the rail is energized at the proportionate high voltages and frequencies, it can levitate and move the train forward/backwards- similar to an electric motor. The person who made this video needs to go here /watch?v=aIwbrZ4knpg&feature=r­elated

[hjgfweuryfgwuyegfuyw]

so it is just a magnet huh? could it be a metal as well?

[theKRISSsuperV]

The Japanese are smarter than Americans.

[GaolisVideoLog]

@theKRISSsuperV Well, because they have a faster, cheaper and more efficient public transportation like the Chinese, Germans or French, while the US throw money out the window buy using busses and inefficient cars that suck up gas like water?

[kamixaki]

@nekroalex a simple magnetic motor that chases its own pole could be the answer to that

[Banana666]

huge arms on a teacher.

[orange12089]

thats a solid, not a liquid.

[GarrettAndersonTV]

why cant this be a power source?

[Nekroalex]

@GarrettAndersonTV and @1maintoshclover

Because you would spend more energy just to operate a heat pump to keep the temperature low enough for the wheel to keep going.

You can't just create energy out of thin air.

[notsuferatu]

the train doesent float with nitrogen..., its just magnetic induction

[biglincolnman]

@notsuferatu the nitrogen is what allows for superconductivity

[YeOldeHobo]

Why science. Why.

[StixR4drumerz]

is this your phone? and does he know your filming this?

[PX54]

it's not magnatron it's maglev

[SwitchboxProductions]

and where are you from 00maljaso

[SwitchboxProductions]

wrong its a mag-lev. i live and breathe trains. BTW its Shinkansen!

[00maljaso]

0.59 ITS A MAGNATRON TRAIN! fucking americans! its called a bullet train or the real name is shincansen. jeez no wander the americans are dumb as fuck, getting tought like that.

[dadrobit]

@00maljaso you mean "wonder" and "taught"

[abslisa]

HAHA!!

[CrazyUberix]

@00maljaso do some research bullet trains are electric trains, Maglev's are new version trains they are Magnetic Levitation MAGLEV do some research before posting retarded coments

[Ramiel4]

@00maljaso

Thank you for insulting an entire country of people and stating that we are all stupid fucks. Let us all give applause to a certain prejudice fuckwit.

[VintageLoveish]

awesome i want ex credit o.o

[ogiler]

There is no room tempature superconductor if someone finds one we can have vehicles that uses no energy japanese trains uses superconductor but they are activated with electric it uses a lot of energy if someone finds one also he will be very very rich.

[orionasmb]

so if you put it in a magnet with a t(theoretical) room temperature superconductor, when would it stop moving?

[sooper2dooper3]

I am impressed by man's ability to turn science into technology. Wonderful...inspirational

[edfchv1]

I heard about this maglev stuff back in 2002 when I was in 8th grade. I tried to make my own maglev for a science project but I failed since I didn't have a superconductor or nitrogen.

[xtruma]

i loved better watching that nitrogen-carrying magnetic train running in circle on magnetic rails...that was really coooll...

[pwnintime]

not

fake

[iseesquares]

you are retarded

[101100010110111]

retarded how? like a downs syndrome? and how severe? mild or catatonic? you should be more descriptive with your insults you dope.

[TheLostRepublic]

no, not retarded. ignorant.

[angus506]

you're retarded as in mild, there, you have been categorized, and you failed in you're attempt to look intelligent, but that's why you are mildly retarded, IQ aprox. 82

[Joe1729]

@101100010110111 Hahahahahahahahaahahahahahahah­aaaa "I see the strings!!!"

[angus506]

so teh maglev train is fake? haha retard

[MitchellMrMigraine]

They have a super conductor siting in the liquid nitrogen. When a super conductor is super cooled, it and the magnet repel each other as well as attracting each other. When this happens you get magnet levitation. Sence it is a wheel and the air has very little resistance, once you spen the wheel it seems its going on for ever.

[xDecemberFlower]

PRODUCT PLACEMENT

[LeeJHooker]

That is pretty cool stuff man...

[casualbrian]

Maglev trains don't work on superconductors...........

[gabesprofile]

F-A-G

[thepianolover4ever]

wow. that teacher is hot. can i have physics with him?

[xxhasudin]

that guy has some ripped arms

[cloud4an]

the japanese are geniuses

[RobynReginaLyle]

It isn't fake.

[cptblackhawk]

physics is not fake

[forgetfuldays]

@cptblackhawk It may not be fake, but in physics the word "phenomenon" is used a lot, because there are many things we cannot explain.

[annihil8ted]

go to school.

[leroyjenkins369]

this is not fake ive done thiss

[animespreader]

Looks like a dope class, he seems like a chill teacher. Extra credit just for looking up info on the internet?

[sheepball]

that was amazing

[latenight003]

Hmm? When there's no wasted energy(thermal energy), does that mean that the kinetic energy remains the same allowing it to continue spinning? I dunno. I'm a science noobie. q: 5* though. :D

[mecrazy5]

Super conducter technology will be the "fuel" of the future, if only they can find away of keeping the liquid nitrogen the same tempreture Permanantly nay longer.

[skomer26]

they could do it in space and keep it a constant temperature

[thegreatMSG]

I just think that if it is possible for the rotating magnet be able to use as a turbine in the future (Free energy!!!!!)

[wraith0127]

Not quite "free" energy, the superconductor needs to stay very very cold to work (about -166C), how do you plan on getting it that cold and keeping it there? You might say liquid Oxygen or Nitrogen, but how do you make it? You need more outside energy to make those liquids. I'm not saying it's impossible, just with the current technology, it's improbable and impractical. Nice idea though, and perhaps scientists could find a way to do that.

[thegreatMSG]

Yeah...you are right, and in my opinion the most possible solution for this problem is to find a way to increase the critical temperature of the semiconductor rather than fining a way to keep them ultra cool... ^^

[wraith0127]

That sounds like a really good theory. I wonder if it is possible to increase the critical temperature of the superconductor, perhaps to around room temp? I think the only major hurdle would be that the speed of the atoms and their density is what causes a superconductor to exist, and that is only at very low temps, for now...

[thegreatMSG]

Yeah it would be already a major break through if someone else can bring the critical temperature of superconductors to 0 degree not to say to room temperature^^'. If that so the wheel in this video would be able to spin by its own by just put it on ice or just built the generators at North or south pole...Ha ha ha!!!!( by the way your second replay to me is actually quite help full and teaches me quite a lot of new info on superconductors)Thanks... ;-)

[FruityLoopsas]

Space is ultra cool, so in space this technology would be ideal....... and we would invent endless engine....

[agentmabus333]

Outer Space?

[sargeantneo1]

" does it really float?" what a dumn bitch!

[onthecuttingedge2005]

Take two Superconductive donuts and put them together with a dielectric material so that they form a capacitor, hook some wires up to each one, then place the magnet on and rotate it on the superconductive capacitor, when the superconductor starts to fall out of activation Tc it will begin to become a semiconductor and it will fire off the stored charge like a cap. just some thoughts.

[bobcrawman34]

hey do i get extra credit if i look it up to

[GyroscopesAndInfared]

dam i wish my science teacher was that enthusiastic cool tric too

[thezeroskater]

that was pretty interesting. it would have been even better if i knew what he was talking about

[EloquentSilewise]

wow! self producing energy! this is the end to our energy crisis!

[fadedfutures]

Wrong. You have to keep the ceramic cold enough, through liquid nitrogen which needs energy to be created.

[eddie2042]

I want pepsi :)

[rayjay15]

That teacher is ripped, haha.

[snylekkie]

yeah nice bicep

[seanconnery4]

it does take lots of energy to make liquid nitrogen. this is one of the reasons why a room-temperature superconductor would be a scientific breakthrough. it would revolutionize everything

[trogusman]

lol you're so close sean.. you're so close.. :D

[Pioneer4ik]

perepetum mobile .... :)

[MrWombatPPC]

Is it only me who see's take it takes more Energy to make the ruddy liquid nitrogen, than would be possable with that kind of device.?

[Darkfoster22]

Your right it does take alot of energy for liquid nitrogen but this can done with liquid nitrogen in tanks I do think, so it will have to last very long . of time.

[SpiritsoftheWolf]

look, it's doing burnout

[roboawsome]

lol

[WoWhacker64]

3 letters, UFO

[need1more1sugar]

it's not flying, it's not unidentified so basically it's an O

[WoWhacker64]

i know, ideot u didnt really think i was stupid did you???

[need1more1sugar]

No and i never claimed you were stupid and since i am such an "ideot" why are you wasting your time that is so precious to a brilliant mind like you on an "ideot" like me.

Before you go out claiming others are idiots please first look at yourself you asshat.

[WoWhacker64]

fuck you, it was 4am when i wrote that OK????????

i was out of it

im going to go kill myself, cya, bitch

[WoWhacker64]

oh ya and FUCK YOU!!!!!!!

why do you have to ruin lives???

[need1more1sugar]

Have fun with that.

[WoWhacker64]

i will

[Rafael0mar]

YeAh, YoU ToLd HIM. hahah ROFLMFAO!!!! ASSHAT... LOL i love youyube controversies, makes the word a pitifully funny place to live ... Have fun with that

[WoWhacker64]

ya, i will (jk)

[Und3rEstimat3D]

i completely agree with u broo (Y)

[winged1joe19]

Ah, and I was wondering how the Japanese bullet train worked. This helps put things in a better perspective. Thank you.

[jcobaltss2005]

its not really how maglev trains work...physics is boring as fuck, and will tell you that when you induce a current through a conductor it will produce a magnetic field. this is called and electro magnet. they pump electricity into these electro magnets of same poles to create levitation. to create movement they have a computer system calculate when to induce a current into the electromagnets ahead of the train so it attracts ones on the train and it moves forward, change strength, change speed

[Yakishamy]

Well i don't know where he is popping out the fact that japanese use it in their railways, because it would cost too much to make it.

[jcobaltss2005]

not to mention the tracks would crack and shit cuz of it being so cold. the inside would be super cold, the outside would be warm from the air so the inside would contract, outside would expand, and the whole thing would bend and deform like a bimetallic strip

[fumamonourequiem]

kind of makes you wonder why there arent any selfsufficient energy plant, that could save us a lot of trouble

[cpringuer]

what class would this have been?

[marceltony]

very neat thanx

[VirginExtrodinar]

What if you provided liquid nitrogen within a circular tube or pipe and kept it cool, then if you were to put a circled magnet on the outside of it, could it spin and increase speed as more nitrogen was provided?

[REHardinG]

only in the nitrogen was directed with velocity at the surface of the magnet at an angle greater than perpendicular then the small amount of friction from the liquid and the surface would cause the magnet to absorbe some of the kinetic energy from the liquid nitrogen. you will never get energy from nothing its always just a transfer between one body/material to another

[VirginExtrodinar]

Greater than perpendicular as in a slant? Would the angle have to change of the liquid in accordance to the change of motion of the magnet forwards and backwards? Also I understand that all energy is used, however is there anyway of actually keeping the liquid's kinetic energy? (Like a battery looses it's power, but then you're able to re-charge it)

[hackedminds]

At the risk of making someone a billionaire at my expense, is it not possible to make a large version of this and hook it up to a dynamo and generate energy extremely efficiently?

[iwanthalo3]

it would take a lot more energy to make the liquid nitrogen than you would get out of the generator, which would need to be spun again every-so-often, and the generator would increase friction to the point where even if it did spin, it would stop so quickly, it wouldnt be viable.

[gavincurtis]

The drag from drawing electrical energy from the rotating magnet and its field will cause it to stop spinning by EMF eventually.

But could be a potential for a very efficient transfer of mechanical into electrical energy (motor output into generating electricity or visa versa).

But ultimately, you still have to provide energy input to keep that nitrogen in liquid state. So any gains in that apparent 100% efficient system is lost.

[GreenKoldAid]

put it side ways to make it float O_O

[abizzo]

UUUUUUUUUUUUUUUUUUUUUUUUUUUUUU­U

[intelpentium5]

i learned something

[Souhii]

He never said the Japanese did it first. He just stated that the Japanese has a train using the same technology.

[random1peter]

He said "it's almost like perpetual motion

[trw45q]

this video makes me wanna have my time at school back... and learn something :p

[littlecuzz34]

i wish my physics teacher did shit like that

[anth427]

so with this experiment, can someone make an EXACT replica of the our solar system? like a mini-SUN mini-Earth ect.? that'd be cool wouldnt it?

[animesis]

the Japanese were not the first to do this actually it was the Europeans, get your facts straight first if your going to teach them please

[GUKIMER]

Listen!!!!! he didn't fucking say FIRST, he just said they had one.

[animesis]

i suppose ur right... but the Mglev trains dont use Liquid Nitrogen, just pure magnets, sorry for mishearing what he said ^^

[Odinn08]

OH LOOK! Pepsi

[Joo3l]

your teacher looks hawt!

[SSJDrakenZ]

This guy is an idiot, it's not perpetual motion if you must keep feeding liquid nitrogen to keep the ceramic cold. It would be perpetual motion if the ceramic kept itself cold forever as well as spun the magnet.

[biggreenblob]

he said specifically that it was NOT perpetual motion. you have to actually watch the video before you post a comment.

[crapkillerz]

He said it is ALMOST like perpetual motion, gotta listen :D

[Tdani81]

If magnets generate enough electricity we would be able to freely power our homes and save on energy! I see this as the future in the making

[kyle44422]

of course the japs found it

[Buzardero]

i hate pepsi

[biok2006]

omg the stupid ask if is real hahahah... noooooo is bs from the teacher.. asshole

[johnknoefler]

if that is liquid nitrogen in the "container" then he has to have a magnet in there also.

[1ToNJaB]

cool. we never had cool demos like that in school.

[johnknoefler]

looks more like dry ice. I don't see any liquid Nitrogen. .

[PostTheMissing]

Its in side of the cup, so if they dont show you the inside of the cup, of course you cant see the liquid nitrogen. Besides, why would you think it would be dry ice. Its not like you can see any dry ice in the cup either.

Both liquid nitrogen and dry ice sublimate.

[johnknoefler]

ya you are right both substances sublimate. But that is completely dry ice. Liquid nitrogen is just that. LIQUID and the magnets are much denser. So go try it yourself and you will see liquid nitrogen will not support a magnet. Dry ice will. This "science" teacher is vague and sloppy in his lectures. He doesn't understand that the liquid nitrogen on the trains is to super cool the magnets. Besides, the trains are only prototypes. They are not practical.

[PostTheMissing]

Theres a piece of ceramic under it.

Its a superconductor so when it gets cold, it repels the magnet.

I agree the teacher should of explained this more

[kartkid100]

maglev trains dont use liquid nitrogen through the rails, they use electromagnets.

[johnknoefler]

They have used nitrogen to super cool the electro magnets. So this science teacher is moron. "look it up" "ya look it up" "they put liquid nitrogen through the rails" What a moron.

[brumanima]

luxury and futuristic train

[OktoPlasm]

Extra Credit!

[savebigonhot]

wow big muscles for a chemistry teacher

[kuresitos]

I want to do that!!! what is the white thing??

[BMayhew60]

That looks like a styrofoam container. Inside it would have to be a piece of a superconducting material like YBaCuO. It can't work though without being really cold, so you pour in some liquid nitrogen (the evaporating N2 causes what looks like smoke). The magnetic levitation occurs through flux trapping. IF you can get a bit of superconductor, a magnet and some liquid nitrogen, you can do it. You have to push the magnet into the superconducter to get it right first (it will repel initially).

[Fartbelly]

NERD :D

[SirusDiarota]

Maglev. The Japanese have it, but we designed it. Only reason why it's not here in the UK is that the government refused funding for the project.

True Story.

[r0galik]

lol what an idiot

[beliel122]

did he grab the ice at 0.43 o.o

[stackster88]

yeah but i only hurts if you hold on to it for like a little bit longer than that

[eueadan]

u can grab dry ice for likr 6 secs

[brumanima]

you mean this wasnt some kind of whtie colored holder, was it the liq N itself beliel122?d

[12345635]

this guy looks and sounds like my physics teacher.

[jasondubose2007]

the japanese maglev trains aren't superconducting...

...and don't forget about the non uniformity of the magnetic field of your magnet, that is the other source of losses

[ytSouljah]

i like that bottle of pepsi in the back. man that guy looks buff. japanese trains. extra credit.

[yomudda4]

It'd probably work well in outer space, since the the temp is freaking cold outta the view from the sun that is, plus it wouldn't have any wind resistance!?

[tweevr]

Well there is no gravity in space so it would just float by itself lol!

[omegafromalpha]

moron

[StefanBruegeman]

the system is not yet out of prototype phase.

[mouserorignal]

fun :)

[Zim804]

Now I know how to make a UFO lol

[jasonguyperson]

wrap some wires around that son of a bitch and get some current!

[MeCaritUNot]

i agree

[Borat148]

Very Cool
