I understand that TEBA (Tesla Engine Builders Association) recommends  peripheral disc rivets on 
the runners of Tesla turbines and pumps.  Is this innovation a contribution by later students of this 
technology or does it come from Tesla himself?  It was never clear from the scant literature I can
scour on the turbine.  To what extent is fluid flow between discs affected by the presence of the rivets?

On the inner wall of the housing facing the discs are what's been
described as grooves.  Can
someone
explain what these are for?  Are these grooves concentric circles?  Or do
they trace a continuous
spiral?
Would an end disc and a grooved housing wall resemble a spiral-groove
bearing.  The rotation of the
discs
or runners  would keep the narrow region between end disc and wall
pressurized.  This perhaps steadies
the runners, keep the discs from warping, keep them parallel?
        
Input on these issues would be appreciated.
