The M.W.Youds website mentions patents for his device operating at 7225 RPM to achieve the result he reported. He mentioned gamma radiation present so we are careful.
Our standard gas inductors run at 3450 RPM.
We are working on a design for speeds to 10,500 RPM with VFD drive. Design problems with dynamic balancing , shaft bearing and mechanical seal cooling plague us. In the industrial world products must survive 50,000 hours.

In reply to RC Macaulay's message of Mon, 16 May 2005 21:45:43 -0500: Hi Richard,
Why precisely 3450 RPM? [snip]Ron,
The cavitation products made by Hydro dynamics Inc. apparently differ from the device used by Knuke. Dr. M.W Youds website has a vortex device that may be closer to what Knuke worked with. Youds speculated some " events' could occur that may be what happened to Knuke. We keep a gieger counter handy when testing water vortex research devices at rotational speed above 3450 RPM.
