This a post pasted from the LSOC, but though you guys would like it too

Just thought i would enlighten everyone on a couple of new changes to future turbo design that will be revolutionary (evolutionary?) in the near future. Before i go on, I don't have an auto engineering background so if i say something incorrect or piss off someone by all means speak up...or forever hold your peace!.
Anyway the two new techs are air bearings and electrically assisted turbos.
The first, air bearings, is a major step to the design to a turbo. If i asked you what is the main disadvantage to a turbo what would you say? High heat/friction/lag time?
Well instead of having a conventional sleeve or ball bearing on the turbo shaft this would be replaced by a thin layer of air which produces virtually no friction and therefore a lot less heat. As you probably know from high school physics when an object is travelling at high speed it's surfaces are generating high or low pressure fields. Therefore an object placed near this surface starts to 'float' (or in the case of a plane the object itself, the wings, starts to take off). The same principle keeps your hard disk heads floating 1/1000th inch and prevents them from crashing into your disc surface at 5400/7200/10000 rpm. In fact air bearings have been used in hard disks for quite a while now. All the research & development has been on how to apply the air bearing to the more hostile environment of the car, what with the higher temp, much higher rpm(>100,000rpm) etc. Also when the bearing is at rest, it's actually touching the inside wall of the shaft. Special dry lubricants patented by the us army have reduced the spinup/down friction. So this airbearing promises to make a turbo that might just outlive the rest of the car, even if you don't have a turbo timer!
The next part, when i have time, will be a quantum leap to the mechanics of a turbo engine, therefore merits a second part. The electrically assisted turbo. To keep your whistle whetted(?) it promises to improve considerably the efficiency(read more speed!) of the engine by removing a load from the engine crankshaft, provides boost from idle(alright!!!), improving feedback from a turbo five-fold, and does to the turbo what efi did to the pre-efi engine.
Stay tuned!

sounds tops esp the air-bearing. it really was only a matter of time for this development.

Sounds good.
Has to be said - Thats good, because i evolve. But i dont ....... revolve.
