  • I WANT ONE!!!!!!

  • I am writing an essay about the uses of a YBa2Cu3O7 superconducting levitating disc. Does anyone know how could this frozen disc be of any use to humanity, besides the posability of levitating vehicles??

  • Why is this guy playing with LN2 without any safety gear at all? Not even a pair of gloves?

    He'll be the first person to lose a hand in a model train accident...

  • @grantemsley1 LN2 is pretty safe to handle without gloves. It takes constant exposure to freeze the skin.

  • INVIZINGED

  • are those neodymium magnets because those are retarded expensive and would explain this small scale.

  • Can anyone tell me where can I find super superconductors ?

  • @123walb search google for "superconductor kit" and you should get some good links. also search shopping for superconductor

  • @123walb go to the links on this video.. they sell this train set and the short bar for about ten thousand us dollars

  • Comment removed

  • isn't that quantum trapping??

  • It is the future in our hands ! amazing video !

  • Look! No gloves!

  • Getting minus 190C without nitrogen... now that's the real question.

  • We need room temperature super conductors right now!

  • @Muscleduck and that's why we must nuke the Na'vi

  • :O

  • I'm 25 and I want this for Christmas. Santa, if you're listening, start gathering some super-conductors.

  • Comment removed

  • how much force or weight would have to be applied to the top of the train to stop it from hovering?

  • HAH.... what?...

  • Hola

  • loved it. . .

  • Where can I buy a model of a maglev train, or where can i buy the needed materials to build a track like this on my own? PLEASE HELP :-)

  • @thatBoymathi You will need some YBa2Cu3O7 and liquid nitrogen. Also, a magnetized track.

  • Is the track ferromagnetic or paramagnetic?I have not seen this "distance memory" effect before.

  • Make a hoverboard

  • I know that superconductors repel magnetic fields by producing a similar field, but how is this train staying on the track? This is either fake or the train is more complex than we're being told.

  • @smittythesmith

    "how is this train staying on the track?"

    The supercooled object seeks to minimize magnetic flux change. To do that, it must stay on the track. Why does it want to minimize flux change? It has diamagnetism, a property of a material resisting changes to a magnetic field. You usually observe this by increasing the magnetic field, which will cause repulsion, but it can also cause attraction, which happens when you try to remove the diamagnetic material from the magnetic field.

  • This would never work, liquid nitrogen would have to be kept poured into the train, we need a force which is clean and easy to create, such as M.A.G.L.E.V technology. would we want supercooled nitrogen lurking around the streets, M.A.G.L.E.V is the future! But i have to say both ways do have a major error, there is no magnets under the ground, we would need magnets under the ground fro either one to work efficiently and correctly.

    Also Nitrogen fuel forever!,

  • They should sell it at kranaks

  • does anybody know how to make a conrtainer for the Nitrogen?? the one mounted on the train?

  • Someone should make room temperature superconductor. And give it out for free.

  • What did you use to make the inside of the train??

    please i need an answer?

  • Now I know how UFOa work XD!

  • The Researcher should KNOW BETTER! Handling that stuff without wearing protective gloves is way stupid---typical male! U have to always use safety/protective devices when handling liquid Nitrogen, Oxygen etc! I love the science and the train and think this is the wave of the future but not in the US as we have to many "pantie wastes" who want us to go back to the "horse and buggy"!

  • @rangeclerk You are right about the US. It's a shame that you are so, so awfully wrong about the handling of liquid nitrogen. Liquid nitrogen has quite low heat conductivity, so brief contact with it will not harm you. Furthermore, it evaporates instantly upon or even before contact with human skin. Wearing gloves would actually be the "way stupid" way of handling it, since the liquid would get "trapped" in fabric and cause actual freeze burns.

    Also, what's with the "typical male" statement?

  • @konayasai Still think it is a stupid way of handling Liquid nitrogen and the "Typical Male" is the "Macho Man" who does not use safety equiptment; that being gloves, and eye protection---Had a chem/physics Professors many many yrs ago and both of them always stressed the point of "no matter the substance or experiment, always wear safety equiptment." Better to be SAFE THAN SORRY.

  • @rangeclerk You totally miss the point. The "safe" way of handling liquid nitrogen is to NOT wear gloves! Small spills on bare skin won't really hurt you, but small spills on skin covered with fabric will trap the fluid and badly freeze you!

    Also, you're a sexist for saying that. I don't know what country you're from or what decade you grew up in, but in this day and age and in my country (Sweden) the "Macho Man" stereotype has been virtually extinct for the last twenty-odd years.

  • @konayasai Got ya! First am a Yankee and an American Male! But there are so many "dudes" on this mudball who do stuff without realizin' they are actin' like a Macho Man---will always wear safety equiptment and that means wearing sealed gloves and glasses and stuff...oh ya am 59! When I turned 50 use to tell folks at work I am a "JR Gizzer"---about 4 yrs ago dropped the "JR" from the Gizzer---

  • Better idea about Russian women gettop5.info

  • now that is magic!!!!

  • @mjtunstall1976

    No, it's physics.

  • @SuperKranius same thing lol

  • How much did the track?

    And the project in total?

    I'll make one but I think Maglev is going to be expensive ...

    Thanks

  • Now we need a research about hoverboard

  • GREAT

  • this is already a reality in japan

  • wow! i need more info

  • the man who finds out a compound that is superconductive at normal temperatures will be rich

  • this dude needs to read up on his lab safety manual; WHENEVER you work with liquid nitrogen, you wear gloves!

  • what are the materials?

  • Wow!!!!!!!!!!, just amazing. But, without liquid nitrogen, not only will the train wouldn't move but, the friction will occur and the temperature will start increasing rapidly?

  • can i do this for a science fair project? im in the 11th grade please answer asap.

  • @win2rgirl yeh. u do it for year 12 physics

  • AWSOME..SUPER AWSOME!!!!

  • what's the soundtrack(s)?

  • what would happen if you had a metal spoon on that train ...

  • @jmills1501 Nice question... Never thought of that.. :D

  • 2060

  • @AZURA888

    hi

  • that's HELLA COOL!

  • hmzbrauche dringend beschäftigung bin so einsam! Jemand lust zu chatn

  • çok ilginç, gelecekteki trenler

  • çok ilginç

  • This is cool, but we need to find a room-tempeture super conductor.

  • @vivalaresistanc That is what they are trying to make.....or find a material that is not on the chart yet...,but their is a few fundamental clues they are missing.

  • we are looking at the future

  • Look like Star War's spaceship

  • Super, maybe in 2121 year it looks reality.

  • @Tomasinio77 they already have these trains in japan

  • Is the superconductor solid material, or wound tape etc? Where can i get my playful hands on it? Is it verrrry expensive?

    Does superconductor "lump" become a magnet with the same field (but opposite) as the permanent magnets below?

  • It is a solid yes, and some are downright poisonous.

    Bear in mind, that not only do you need a superconductor metal, you also need a powerful coolant to make the metal supercondutant, such as liquid nitrogen.

  • The only problem is that you need energy to reduce the N2 temperature to liquid state...

  • BWAHAHAH fucking awesome!

    <3 Germany

  • @W1NT3RMU7E

    Hi

  • @W1NT3RMU7E Germany = Fail.

  • @blackcrow6667

    not trying to feed you with this comment, but please troll elsewhere.

  • @W1NT3RMU7E Here come the Holocaust Train, Choo Choo!

  • Woukld be interesting to put a graphite shim in the track...

  • "On top ot that, it really steams"

    MUAHAHAHAHAHAHAHA

  • Not in the sense that it's easy to obtain and maintain in a liquid state.

    In some ways it's like ethanol - it is renewable in the sense that you can never really run out, but making it, transporting it, and storing it are expensive and the motors are still going to require non-renewable resources to make.

  • I WANT TO MAKE SOMETHING LIKE THIS !!

    well 2 bad i cant get any liquid nitrogen = (

  • is this superconductor is bismuth strontium calcium copper oxide??

    is it available in the market?

  • it's actually bismuth technetium hydride

    lolz

  • Is it practically possible to do it?

  • The atmosphere is nearly 80% nitrogen; so I doubt we'll run out anytime soon.

  • @MCH1984 I alwasys thought it was 90% oxygen.

  • @MCH1984 My bad. It is 80% nitrogen!

  • @MCH1984 On top of that, the nitrogen just evaporates into the atmosphere anyway

  • @MCH1984 yea its gaseous though... not good enough

  • @JrDarkPhantom True; as with hydrogen bottling the stuff almost pure is surprisingly difficult and rather expensive.

  • People seem to think that this train will run forever with little-to-no electricity. While it's more efficient than current maglevs, you still need energy to generate liquid nitrogen (fairly cheap), make the turns (expensive but manageable) keep the conventional magnets from losing their alignment (fairly cheap), and to replace the very large and heavy high-TC superconductors that make the train work (ridiculously expensive). The fact is that these two parts will all decay rather quickly.

  • woww!

  • Wow like a matchbox model of the early 80's

  • something rather pleasing about that

  • Amazing! Simply Amazing!

    A fine example of Newton's (first?) law?

  • hi i hav a innovative project using superconductor but i cant get liquid Nitrogen can any 1 of u guys tell me how to get it in India???

  • Do you have Linde gas in india?

  • How much are the models?

    Are they ££££

  • i hate celtics

    but let's go green

  • theres no problem with that because is less expensive that gasoline and can be used with bovines of pressure to keep liquid the nitrogen i make this experiment once and result very impressive and functional the only problems that we can find is that put one of this on some city its ultra expensive and needs to have infraestructure and the speed can be controled too with te bovines

  • @playanudista88 Bovines? What does this have to do with cows?

  • this douchebag hasnt heard of air resistance...stating no resistance like its a cold hard fact

  • coolest shit i ever seen in my life.

  • i dunno. i guess it depends on how you look at it and what your idea of fuel is

  • aja si esta bueno!ª coman mierda cerotes

  • i dont have no funding, im putting my idea here on youtube, so hopefully sombody will STEAL IT! im sick of the crap rail system!

  • Here's the problem with that idea: your trains would have to be spacecraft to work -- you're talking about running trains in hard vacuum, which is equivalent to putting them into orbit. Extremely expensive and dangerous to operate. Also, the amount of energy required to maintain that hard vacuum over long distances will be extremely high.

  • ok, well i dont know much about vaccums or how strong the vacuum would have to be. I guess you figure the vacuum needed would take more energy than these maglev systems.

  • So it uses potential energy and gravity to accelarate to massive speeds with little friction, assuming low friction wheel design, and the steep slop at the other end of the track is used for breaking back to zero. It unloads moves to the other track which of course is opposite and decends back to point A. No power required no fuel, and no magnets.

    Any questions?

  • Comment removed

  • No fuel? the liquid nitrogen is the fuel when the nitrogen evaporates it stops.

  • the liquid nitrogen provides no energy. the initial push is the "fule" and since there is no friction perpetual motion is possibleand inertia arries it until the magnet warms

  • The Nitrogen keeps the conductor cold enough to have its cool effect. That goes way the conductor heats up and the friction takes place. The friction comes on now motion so the nitrogen in this case is like fuel.

  • That's like saying water is a ship's fuel. The environmental heat is what uses up the nitrogen, not the movement or hovering.

  • DUMB idea, i have a better one. Feel free to steal it.

    Build 2 tracks from point A to point B in a straight line.

    Each track starts at a higher altitude,either above ground or at ground level, and gradually decends at a slight slope of approx 5-10 degrees(maybe less), and ends with a steep slope bringing it back to starting altitude.

    Construct a tunnel around the tracks and evacuate the air, eliminating air friction.

    Train will slowly accelerate to massive speeds, with no POWER!

  • cockgobbler

  • I thought of the idea of magnets for levitation on cars and trains. But i guess these guys stole it.

  • i wonder iin our lifetime if we are gonna see real trains like this!

  • prob not this tech is very nonefficent

  • actually there is sumthing like it in japan or china i forgot

  • it kind of kills it when it looks like the carriage is on fire too

    cool though

  • i SOOOOOOOo want one!!! how much do these things go for?

  • um

    thats KIND OF awesome.

  • LOL yeah it is. I'm writing a paper about this

  • Wow. That is **amazing**. Thanks for sharing it.

  • I want these on my foot!

  • lol

  • awhawhaw so funnyxD

  • i wonder if that would work?

  • Very interesting indeed. Thx for uploading this. Amazing to watch.

  • AWESOME, They should make wipE'out" a reality!

  • you should explain propulsion for it becuase im 11 yrs old and i need to know how to propel it

  • The propulsion of this type is just basically magnets pointing N/S, when they are alligned correctly they propel, attracting then reppelling. I actually jsut finished mine yesterday for a science fair. :-)

  • needs to use a maglev train shell.

  • This is really cool on super conducting train model.

  • is there no disadvantage? help! i need this for it's our project!

  • #1 how you keep it cool at -183ºC all the time?

    #2 the rails are regular magnets. If you are building a big train, you need really big magnets, and the only way is to do this is powering up the WHOLE railroad, and you need a LOT of electricity for that.

  • I want one.

  • Won't you have a cold burn from touching the train? And if this is going to succeed, the world is gonna need a lot of liquid nitrogen...

  • The Problem with this Technology is similar to what a fridge does,you see Nitrogen keeps the earth cool,and if for some reason this technology became popular on trains or what ever,then the world would heat up faster,and this fact needs to be addressed,for any one thinking about using this technology,you see there is 78.08% nitrogen in the atmosphere,so if this technology becomes possible then that 78.08 percent that keeps the Earth cool.would go down, while the earth heats up.and that is a fact

  • Bravo. I'm amazed.

  • Thank you!,i just want to say to a lot of people out there that wonder why Irish people are not on the physics ranking from country to country,is because our patenting system in Ireland,wont allow Irish people to patent any thing associated with patents,look it up under the Irish patent!,which is why we are no where to be seen,but we are above Russia and the USA in Mathematics!,and that's a fact!,some patents to London to be approved,which is a joke as far as independence goes!

  • Show off

  • no i am not a show off,i speak the truth!,and i always tell people to research the facts,and if they cant find it,i give it to them.i am a head of my field in Anti gravity in polar Engineering,i have really pushed the boundaries of Anti-gravity in physics,but since i am Irish and live in a country that is bound by politics and Neanderthal Patent law, i keep things to my self,and i don't trust those Anglo Irish Professors in Dublin,but to be honset they are not Irish,shower of bastards!!!

  • I find this insulting, dumbass. I dont give a shit of who the fuck you are, you are a fuckin showoff.

  • Better be quick because I'm patenting my anti-gravity device this week.

  • HAHAHAHAHAH!,

  • Wow, that's quite a mouthful. I guess your used to that sort of thing

  • ha mouthful lol

  • hug trees much?

  • shut the fuck up wanker

  • Brilliant!

  • How much tesla does this use? I saw ...4,35

  • Thats really cool! how much weight can the carriage hold before it sinks to the track?

  • Too cool!

  • hmm nice :)

  • imagine a way to start the train without straight hand contact

    i dont know, i think i'd use some jet motors or something like astronauts use to move in space, some compressed air to make it move, and the same with the brakes, just in the opposite direction

    it's so awesome, no friction = great inertia :)

  • So then what happens if you set it on a "track" made up of a series of computer controlled electromagnets. If it's 'holding' the field - could a change in the field as programmed by the computer cause a change it the direction of the 'train'? What if the surface was the superconductor and the vehicle was a series of computer controlled electromagnets?

    Hmmm...Times like these I wish I were smart.

  • I think that the train should be superconducting not the track. It wouldn't be economical to keep a hole track below 183 Celsius besides these materials can be rather costy to use them as track.

  • You mean like a MagLev?

  • great!!!

  • so how do you stop it? do you have to calculate in advance when the liquid nitrogen evaporates?

  • There are many ways of doing it. You would needs to insert some sort of resistance to counter the forward motion of the object. You wouldn't want the liquid nitrogen to run out in this case, or the magnetic levitation/suspension would be lost and the object would drop to the ground. The trick is to able to activate the super conductor at normal temperature instead of at its critical temperature of 71 K ( I believe that is the temp).

  • thank you for the explanation. i'm sure they'll figure a way.
