I'd like to ask the silly question here, but, where does the pressed air comes out?
Maybe i missed something...

Thanks for the tuto.

.:FFH:.

You're not!
This IS a stupidly designed device.
the air actually escapes thru the shaft hole.

This is actually correctly designed, with the exhaust escaping through the shaft hole.

The Tesla turbine relies on the boundary layer effect and centrifugal force. The air gets forced to the center and out the shaft hole. An exhaust port on the side would ruin the design of the turbine.

no. CENTRIPETAL. not centrifugal. why does everybody think its centrifugal??

Centrifugal doesn't even exist!

Centrifugal does exist, it depends on your plane of reference. If your plane of reference is the object which has a centripetal force acting on it, there is a centrifugal force.

Nope! :) Centrifugal is merely inertia perceived as a new force.

It's all to do with plane of reference.
If you have a rotating plane of reference, you can have a centrifugal force. Look at the Wikipedia article for it.
