* * I did miss that! However, I have seen ultrasound generating equipment of various types, both electronic (Stringham) and mechanical (the Hydrosonic pump). I know a lot of readers have complained about what may seem to them like overly-heated arguments of late, but sometimes important insight can come out of the give-and-take process of digging as deeply as possible. This may or may not turn out to be a key piece of the riddle, but it would probably have not become apparent at all - if we had not been struggling to find correct answers without guidance from the inventor. The ironic thing is that Rossi may not even appreciate this cavitation route. My guess is that he will be using a high flow pump from now on whether it is understood or not since he got better results with the high flow. Jones
