Crealev levitation demo

[nilaozi]

There is no actual sound in the clip of this prototype.

I guess other similar clip has no sound too.

I think it is because the Spinning motor is noisy. This could be the 'upside down version' of LeviTron toy, where the bottom black plate got wired motor spinning a magnet at high speed, and your little black plate on top does not need to spin, to float on it.

Am I right, Crealev?

[kungfuseadog]

Fucking magnets. How do they work?

[valcarni1]

Cool.. only 4 more years til we have hovering skateboard parks like in back to the future 2 lol

[unohoo09]

Can a Mormon please explain how this works?

[QueefTaco]

Oh shit, Are we in Limbo?

if so I am hitting that bitch mal

[dezrad11]

how much does this cost???



[dezrad11]

how much des this cost???

[71296105195]

if they can keep inreasing the load it can repel, we are very close to the new age of man. magnets.

[Siemah]

@71296105195 I wonder how people with pacemakers feel about that :)

[71296105195]

@Siemah good point.

[danielcarlo01]

what's the name of the "black thing" and the "silver thing"?

[Siemah]

@danielcarlo01 The black thing is called the 'base' and the floating thing is called a 'carrier'. And they now have a new one that can lift 10kg! :P

[KnightChatX]

What about adding gas that's lighter than air?

[TheLuisinho666]

incridibile

[aaronrocks87]

could you do this with your Ipod or would it screw up the circuit

[Siemah]

@aaronrocks87 You'd have to ask the guys who made it but I don't think a strong magnet like this is good for any electronic device...

[MrAwsome514]

@aaronrocks87 Well that depends. My guess (a relatively educated guess) would be that this device uses lenz law for the levitation. This would mean that an electromagnet (mostlikely multiple electromagnets for stability) being powered on alternatingcurrent at a high frequency are inducing electric currents into a metal plate in the levitating disk. This causes a magnetic field to form around those currents repelling it away from the coil/coils. (Too long see next comment)

[MrAwsome514]

@aaronrocks87 If alternating current is being used in a coil on this device then yes it could induce current inside the circuitry of your Ipod or other electronic device which could damage it. However if I am wrong and the device does not use alternating current then the risk of damage is significantly lower but still present (though still highly unlikely).

[elfmetereins]

levitation or blown air?

[Siemah]

@elfmetereins magnetic powerrrr

[mindstormmaster]

Now if only they could make it work with a non-electromagnet.

[viniciuspedrozo]

I need emails and paypal account.

[jewifeifei]

are these avalible to buy?

[viniciuspedrozo]

How I can buy?

[2xAtotheRon]

It has been shown that a system consisting of two opposing magnets will have a saddle point in only two directions - the system is in unstable equilibrium along the third axis, thus no levitation. However, if one of the magnets is spun, the system is placed in a state of dynamic equilibrium. Usually, one sees this trick done with the floating magnet spinning. In this case, it is the magnetic in the base that is moving. Hence the visible cord attached to the base and the lack of sound.

[longboarder717]

it's called the flux effect or something? but i thought you need below 91 kelvin to do that

[xXx00701]

i know how that works, they are both magnets. one is negative and i think the other is also negative, causing it to push away from each other

[wikinerd]

@xXx00701

Slightly more than that, I should think. A simple negative-negative would not hold a stable levitation that easily. Something more along the lines of flux pinning is probably responsible for this...

[matthias2986]

agreed: still i beleive this device to be simple, maybe 2 magnets in the levitation platform of opposing feilds, one center, one around rim - then one eletric magnet in the base to acheive a push and pull. maybe not i really have no clue how this device works yet, i think i will check into it...

[survivorevil]

u are a fucking genius!!!

[isiah29sixteen]

ok now make a root beer float

[vlaxatron]

cheap

lol

[Rainy0ayProductions]

then why do you watch it

[Mailit2marko]

hamster fun

[LocustsOfSteel]

I would put my weed in it!

I have been trying to find a levitating dish for a while now, & now i have at last found it.

*QUESTION TO ANYONE WHO KNOWS* does it sell for $50 or less?

[clod262]

I want it!!!! great!

[lankey32]

I would put my mixed drink on it!~

[star0the0legend]

thats not even a magnet!

[niiidar]

How do you know that it is not a magnet?

I think it is, there would be no other explenation (Except for a superconducter. Which is very unlikely it is.)

[jjaacckkwweebbeerr]

your fucking stupid!

[bakosburner]

lol you say that yet you put your instead of you're

[jjaacckkwweebbeerr]

oh no i put what i meant

[CO0LTUBE]

..... just shhhhh

[chattmataz]

where do i get on of those? if you put a bowl of dip on one and nachos on a nother that would be a cool idea for snacks when your buddies come over for the game :-D

[Xykarioz]

omg, look what you think about, ur so american haha

[chattmataz]

I´m american????

[verduras]

wtf are you talking about dude

[Xykarioz]

the first thing he thinks is eating nachos.. jackas

[jjaacckkwweebbeerr]

dude, fuck you. i am so sick of douchey people from other countries thinking that all americans are fat and stupid rednecks

[jjaacckkwweebbeerr]

Ah yes the 2008-2009 varsity state champion in pole vault, long jump, and high jump is a fat stupid redneck.

well as least i know that americans can spell cause you sure as fuck can't

another note: in america there are americans, not a single american. just to clear that up for you

[jjaacckkwweebbeerr]

no, no you didn't

[tj1990]

and to you...are you that narrow minded and stereotypical? open your all seeing eye.

[tj1990]

you pwned.

[Herooftheday64]

He's not American...

I'd set a double quarter pounder with cheese on it.

XD

[Xykarioz]

lol

[KaSzTaN1275]

UFO :D

[magictutorials123]

my science teacher has someting like that only its a magnetic globe

[AZURA888]

It could be foucault currents induced by an alternating current coil under a metal sheet.

[UpcomingJedi]

Yet another useless gadget.

[Anoninfinity]

Why do people like you exist?

Please do read the title and description before watching a movie.

Doing this clearly indicates that this is a Demonstration. demonstrating levitation of an object, taking in question if this were posible large-scale e.g. floating vehicles/trains.

[calebthellama]

but its so fun to play with

[arinhyspam]

Now I know that in lots of things to do with magnetism, there is some energy lost through magnetic induction (making a current). Does that apply to this? And about this limit... Even if it's done in a complete vacuum, the fastest you could get it going would be the speed of the driving force. You'd have to use light to get the edges up to that speed. What happens if the outer edges of the disk are going close to the speed of light, when the middle is hardly moving?

[thedefog]

LOL the wise-ass comments on this page are hillarious. I particularly like the one about a "limit" to it's max speed and the Physics guy's comment about air resistance.

[schawt]

Two words: floating coaster

[KnightChatX]

The cool thing about that is it's frictionless, so if you ran an electric motor like that to produce power if wouldn't have friction so you wouldn't need oil to lubricate a physical metal surface.

[Siemah]

Interesting suggestion, canceling out friction could save a lot of energy

[Jadedoto]

No, absolutely no friction because air resistance does not exist.

[jjaacckkwweebbeerr]

dude if air resistance did not exist then planes could fly much faster...dumb-ass

[Jadedoto]

I have a degree in Physics. I was being facetious.

[DJMonk3y]

If air resistance did not exist.. the planes would not be able to fly AT ALL.

[commandercool1337]

true

[Zethux]

Explain The Sun and other planets, then. It's the gravitational pull, not air resistance.

[cuteboymimmi]

@Zethux LOL!!!

[alan3djoseph]

LOL, without air resistance planes would fall out of the sky. Wings and engines would have nothing to push against.

[modwebby]

lol a plane uses resistance to get lift..

and the shape of the plane uses to lower the resistance but the wings need resistance to have lift, and on alan3djoseph's commend bout engines, you can use rocket power, they dont need resisitence from the outside --* points at space*

[demigod76]

@KnightChatX there is the friction of the air. To prove this, it will stop spinning sooner or later.

[zyarc]

This looks like better technology than most of the magnetic levitation junk that on the market. I'd buy it if they sold it in the states and the price was right.

[EinhanderSn0m4n]

Cmon spin it faster! FREEBIRD!

[Siemah]

I wonder if there's a limit to how fast it can spin, it being nearly frictionless and all.

[uniraptor]

A limit? think about that.

[LocustsOfSteel]

that would only be based on how well balanced it is.

[kitcatkitty505]

thats really cool! :D

[solomonsk1]

weak

[therealeaea]

wow

[Qwerty0791]

The disk can also be very light weight, just a low, steady, flow of air could sustain it. But yes, I'm sure polarity could also do this.

[Siemah]

I don't think it's very light, on their website they put larger things on the floating thing like a small buddha statue. I guess they use some kind of enhanced polarity trick...

[InevitableHawk]

Is this polarity?

[Cromag3]

Hmm, ive read that they use a technology only they in Crealev knows about.

But polarity is the only thing i can think about.

[mullanimal]

looks like Superdiamagnetism and flux pinning, the coolest effects in physics :)

[Karan13]

nice
