New idea: Magnetic turbo bearings!
ok guys, i was at school and the some of the steam turbines run on magnetic bearings. now a magnetic bearings is basically magnets that float the axial shaft. the advantages to this is it is frictionless, oil less, and the effiency is huge.
now if someone could make a turbo casing that used these magnetic bearings the lag time could be reduced i think as much as like 100-300%
i think this is worth investigating, i dont know of any turbo companies experimenting with this because its pretty new technology.
what do you guys think of my idea?
heres a link to a company that manufactures these bearings.

Re:New idea: Magnetic turbo bearings!
a pipe would be taken from the outlet on the cold side and ran through the bearing section.
aspirated air.
also the bearings on a normal turbo contribute to alot of heat onto the cold side.. if the exhaust housing had a high heat gasket material to prevent heat transfer that could also help.

Re:New idea: Magnetic turbo bearings!
Not a bad idea. Think of the shaft of the turbo as an electron: floating in space due to polar forces. If there was a way to make the magnetics strong enough to hold the shaft in place, but allow it to spool, or even use the magnetics to help it start to spool, the efficiency would be very high. The shaft would essentially be frictionless.

Re:New idea: Magnetic turbo bearings!
Oh ----, my buddy is going to be pissed. He has had this idea for years. Back when I lived with him he would wake up in the middle of the night and drive to the shop to ---- with it because he thought up something. I'm not even bullshitting. He is going to flip out. He had a few "projects" working. You should have seen the mess he had going with busted *** magnets and ----.

Re:New idea: Magnetic turbo bearings!
Controlling magnets it that way is certainly beyond HMT, but the idea is cool as hell. Just look at Mag-lev systems for another example, those trains do like 200 km/h plus easy, and are super smooth doing it. Essentially with some sophistication you could have coils on the turbine shaft and actually start the spool up electronically, and then once the engine gets going, you could reverse the effect and take the power generated from the electrical system in the turbo to store for the next needed spool up. That'd be phat, but again, way beyond HMT.

Re:New idea: Magnetic turbo bearings!
Since we are discussing turbo charger technologies I thought i would share something I read a while back on SCC.
They called it the hydra charger. More or less same as a normal turbo but instead of exhaust gas turnin the wheel it used hydraulic fluid from a pump off the accessory belt. sounds like a good idea.. instant boost like a SC but w/ turbo CFM/psi... any thoughts guys?
