Body
Norm,
I read your proposal on this when asking about the problem with resonant
technology and tuning for every load. Did you develop the system to the
point of selling it or building a full blown proof of concept?
I was at Feuling engineering when they were running the Tesla turbines
they built for race car water pumps, the energy savings over a regular
impeller pump was from 10-40 times.
I always thought they would be cool in jet boats or the irrigation pumps
they use and watercraft. I don't know about the torque curve though, I
assume they need to be spun quickly but a conical hybrid version with
Schaberger spiral flow would be something else and would likely overcome
the lack of low end torque.
I think the Sr71 ram jet engines work almost in a Schauberger mode with
the variable metering cone inside the inlet cowl.
