Darn near every laser printer, and most scanners have used air bearing technology for 20 years. The product I work on has a 30,000 rpm polygon motor in the laser to paint the beam across the photobelt. Been that way since it's intro in '85. It is very rare that they fail, and most have 24/7 operation for 10 years or more.
There will probably still be those who will argue that "thicker" air will provide "better protection" for your turbine's bearings. Amsoil will sell this "thicker" air packaged in high pressure tanks through a multi-level marketing strategy.
It will be a leading edge, fully synthetic air won't it?
