Re: [TCML] Tesla Turbine

[DC Cox <resonance@xxxxxxxxxxxx>]

There is a huge club of Tesla turbine builders in Milwaukee, Wisconsin.  He
may wish to contact them for more information.

Technical papers I have read, published by Phd's and college researchers,
seem to indicate efficiencies that are not very high.
