First of all, it is nice work that you did with the printer
As far as i know, vibrations release gasbubles from the metal surface and that brings more efficiency.
I am not sure if there is another reaction going on with vibrations...
I think that what you are looking for is a system that when you hit it once, the hit will multiply it self by some kind of resonance?
Or is it an electron avalanche effect you are looking for?
For me, Meyers technology is a wierd one. Why? Because he had several different systems. All which were differend.
The two most interesting ones for me are:
* The sphere shaped cell. Why? Because of the hope that some freed electrons will bounce back and forward on the shiny inner surface.
* The EEC. Why? Because Meyer stated many times, that he extracted electrons who are freed by the water it self, by the self ionization effect from water.
* I never read in his docs about vibrations. Sorry.
But as usual: Keep on going! You do creat!
