Dynamic Geomag: Friction-Free Transmission Gear

[Pyanapple]

This is awesome and I'm 14 and have no idea how I got up here, but look at that!!

[PrimeTargetSecurity]

thx for giving me a new idea. i dont use these toys tho, i gotta nice source on strontium magnets. strong lil'fukrz. i own a custom shop & a security firm so i have these subs i sell and they use 120oz, 140oz, and 240oz magnets made of strontium with the coil being made of kapca (a patented metal) so by mixing 2 worlds i've got alot of ideas working out and this gives me a great idea 2 try. thank you. for the serious ones reading this, try speaker techology and ground-interupt tech. works.

[pyroblaine]

if you give a 10 year old a Phd in physics this is what he will come up with for a thesis..... either that or a really cool robot ^.^

[ross9886]

I believe it will lose energy as heat, caused by eddy currents in the metal parts, which are induced by the moving magnets. As for friction, you should try to levitate the two gears, that would be so cool. Imagine a contact-free drivetrain... Damn, I gotta get some of these geomags!

[Soulrider2012]

This is not friction free as common sense as well as the laws of physics dictate there will be friction. It will not spin perpetually either. It will spin for a short while and stop unless someone introduces more energy into the system (spins it by hand, like he did to start it before filming).

[Blacksite97]

good job dudde _--

[Geniuskid222]

If Im not mistaken those rotating wheels are held in place by magnets which attract it and therefore create a force pulling 2 metal balls one to each other which one turns friction is created between them.

[uberdragonbreeze]

not friction-free, thats impossible, if it was friction free, you would have a LOT of scientists waiting outside of your front door, wanting to interview, and basiacally just annoy you.

[ThePlaymaker94]

AMAZING!

[Scerab]

people are being too picky with this no friction thing. In physics or engineering, if a system has this little friction it is said to be frictionless for simplicity sake.

[goldenman212]

There's still friction on the balls at the top and bottom.

[Dirtboy101]

nothing is frictionless, however, there are many things (like what you made) that have very little friction.

[iammorecoolthenyou]

@Dirtboy101 Actually, if you succeed in creating a space with total vacuum.

Then have two magnets holding a metal ball up in mid-air and spin the ball

Then it should be free of all friction, right

[Dirtboy101]

@iammorecoolthenyou I think, and I could be wrong here, the Earnshaw's Theorum makes it impossible to suspend magnets with the use of fixed magnets. Now applying that to your idea of magnetic levitation, you would require an electromagnet to achieve the aforementioned levitation, which would unfortunately require electricity to power it. Finally, it's impossible to achieve the quantum mechanical definition a vacuum (absolutely nothing in that space)....

[1kwood]

no such thing as friction free... /fail

[RazielKain]

You know

I find your videos interesting the one thing though thats always bugging me is those "FREE ENERGY" idiots who think "THERE IT WORKS"

[gvainskates1337]

Nice

[McFuckNuggets]

One problem: A magnet would have to be pretty strong to work in that manner when you apply 500 hp to one end and a road to the other...

[prepare2fire]

There is a lot of air friction(air resistance) against your spinning machine...

[BreeGaming]

Would be intresting to see the results on a faster scale.. say 6k RPM+ for racing.

[billymagfhloinn]

Torque?

[sharkxelectronics]

it doesn't say the whole thing is friction free, what is showing here is that the transmission of the energy of one wheel to the other is friction free, ONLY THE TRANSMISSION OF THAT ENERGY, there still friction of air, top and bottom magnets and blah blah blah, that's not the point, is just the transmission of the energy of one wheel to the other. sorry for the English I'm latin.

[abrahamstudios]

oh i see its teh same magnetict pulse so there pushing each other

[FlashEF]

It has some friction, even it is minimal. And even if you would make it really float in mid air, the air would be creating drag as well. However, if you put that in a vaccum chamber with perfect vaccum, and make it float in the air touching nothing, it should never stop rotating once put in to motion. In reality it might get stopped by earths magnetic field influence, earth rotation influence and other really minor stuff, but after like a week.

[coder0xff]

@FlashEF Even the magnetic flux is not 100% efficient. There will still be loss as thermal energy.

[kickercaster18]

yeah, but you don't need contact brushes to create electricity, thousands of people have proven that :)

[BHWR]

ah yeah good point, thanks for the reply

[BHWR]

in the future couldnt we put dynamo's on the spinning things and create electricity without having to burn fossil fuels? sorry for bad spelling, and tell me if im wrong because its just a random thought :)

[Malteboy777]

Awesome dude! :D haha.. Made from geomag's.. wow

[snowball1912]

I am suprised they don't hit each other!

[besproductions]

/can you post a vid on how u do it plz :S

[GazerGraff]

how long does that spin?

[RexNunc]

neat

[64298]

How long does this action last once started?

[iEricdaXerd]

forever until you stop it lol

[XeroHeroes]

That would only be true if it was in empty space, but otherwise it would probably last a while.

[ZomgLolPants]

There's also friction between the two spheres.

[findthecomputerroom6]

@64298 if there is zero friction then technically in should go forever

[yomomasface]

is that caused from the magnetic pulls?

[aldoaldoz]

yes

[nikkodabest]

will it go on forever?

[rushfan8]

cool

[SIP100]

air resistance... not friction free.

[aldoaldoz]

Sorry, I'm alone here: I operate in a vacuum!!! :)

[Brok3nC4rrot]

@aldoaldoz actually, there is a minuscule amount more friction: the bearings at the tips of the gears rubbing against the ones on the outer structure

[Gibbstardelux]

@aldoaldoz Even so, there's eddy currents which will slow it down.

[stEPHIQUE]

@aldoaldoz lol, and also the surface friction :) the magnets are in contact, even if it's a single point it also causes friction :)

[TheHadesShade]

@aldoaldoz gravity too, not much of course

[123marijn321]

@aldoaldoz how is it possyble to work in a vacuum?, and dont the balls theirself provide frictrion?

[Jebus495]

@aldoaldoz Still not friction free in a vacuum...

[MrLuke370]

@aldoaldoz most be space you are working in or else you are the richest man in the really god vacuum business cos there are still particles there for friction to occur... really cool tho.

[ventusz]

some friction at the magnets on both gears at the top and the bottom

[ApertureRobotics]

@SIP100 So true there is also friction on the contact of the ball magnets! :p

[Herreviken]

nice video
