Could you make a 'frictionless' bearing using magnets?

[dug777]

and the bearings keep overheating...

They did just that with the MAGLEV train in Germany; look what happened!

Try ceramic bearings.

I guess i could just turn off the conveyor belt, but where's the fun in that

If heating over are they, then with solution cold what is you need.

I wonder if i can buy them anywhere in bulk online? Like 10lbs bulk...

I hear they sell them in alternator sized chunks, raw.

long as the damn plane is not on a treadmill they should be fine.

What if the plane was going to quiznos and considering not tipping? Would it get there?

It would arrive, but not leave.

no it would leave because it would get upset with the business practices of the store.

I'm sure a magnetice "bearing" system is feasible, for certain applications. You'd need a fairly strong magnetic field, proper housing of the innards making the field, and supply sufficient Energy(electricity) to make the magnetic field. That said, I ain't no fancy schmancy city boy with thems new learnins to know what all would be involved or even WTF you're talking about.

Ah, I am corrected.

What "frictionless?" - impossible. . .

 

[Zenmervolt]

Technically they would still have friction from air resistance, but not enough that it would matter.

You've seen "Snakes on a Plane". Now, prepare yourselves for "Planes on a Treadmill!"

 

[destrekor]

magnets do not provide a frictionless environment.. sure they lack physical friction from the envrionment, but a new factor is presented: magnetic friction.
case in point: when watching Top Thrill Dragster, at the last segment of track when the train is coming in screaming, and all that is there to slow the train are large rare earth magnet slabs. when the train (coupled with its own magnets) glides over the magnets, one can view the waves of heat that come off of the magnets on the track. the heat is coming from the friction between the magnetic waves.

Foil air bearings and hybrid air/magnetic bearings are more practical.
