Yes I do believe it states in the patent he made a ceramic mixture from the minerals that make piezo's.
In a certain combination.
You should be able to see that.
Well, sorry, but you believe incorrectly...there is an insulating "vitreous ceramic"...STOVE CLAY...but, NOWHERE does it say piezo....NOWHERE!
This is what it says about it....
"...Said center hollow tubular electrode carries water, and is separated from the outer cylindrical electrode by a porous ceramic vitreous material, and the inner surface of the outer cylindrical electrode exists a space to contain the water electrolysed."
"...The center tubular electrode is coated with a nickel alloy, and surrounded with a porous vitreous ceramic and a glass tube with the exception of the tip that faces the second electrode"
You are making shit up....if you know anything about piezos...they are NOT porous, in fact they are a seamless crystal matrix.
I deal in facts...not assumptions...get your facts straight
I have included the Puharich patent so u can see for yourself!
