I was kind of curious about what happens to a turbine
when you make it smaller and smaller. I discovered this paper at the
UCLA engineering library today. Looks like we will have no
problems. This 1/2 inch diameter compressor still had
65% efficiency at 420,000 RPM.

I am going to contact some of these guys and see if we can get
some academic help for a very worthy cause. Namely 20% reduction in the
worlds use of gasoline for cars. In the mean time we will learn
enough to make some turbo compound rotaries for our use
in airplanes.

They thought it might blow up.
