Re: [EVGRAY] Tesla Turbine Question [2 Attachments]

Body

Thank you Norm,

Great information as always!

Just wondered what Dr Tesla may have used for bearings back then before
off the shelf silicon nitride and such.  Something spinning that fast
would eat up bearings if they were not choice.  Perhaps they were ball
as you allude rather than hydrodynamic fluid bearings.

I shall order your presentation.
