I have a question for you, I have now checked the Puharich patent a bit and I find it hard to understand why he has ceramics all the way up between the cylinders and he just gets gas between the edges on the top?
Have you tried stove clay between the cylinders, do you believe that is something Stan used? Considerring the picture of the ultrasonic resonator in Stan´s GP, what is the material in the resonator? I can easily try the stove clay concept soon, now my pipes are pretty tuned, finally...
Funny this patent. And also he calculates and show us the 120% OU at 300 deg F water temp...

It is not even controversial that claim. Furthermore, low efficient cells draw alot of amps increasing temperature and hence efficiency. So why are we bothering so much about efficiency at room temperature? If you make the water stay cold you get no dry steam... Go-rounds and teeters...
