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

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.
