 Hello,

I understand that piezo effect on quartz or tourmaline occurs when crystals are presusrized and that when epoxy is dry it's doing so..
I can understand that if crystal is falling on a thin layer of epoxy negative ions of tourmaline can escape around in the air. Some months ago I saw picture of an acoustic revive power strip: the tourmaline wos soaked with epoxy in a large thikness layer. How can negative ions escape from this coumpound? It works so how is it possible?

 They could not sell a finished electrical product with loose crystals without getting a big risk of lawsuit.

From a physics standpoint, the epoxy would heat to dissipate the energy.

 The piezoelectric effect has nothing to do with negative ions, but some crystals generate electricity when squeezed, that's the piezoelectric effect. Tourmaline must be heated to emit ions.

 I use toumaline in copper tubes and it takes a large amount to have a significant effect. A thin layer would not effect a whole lot anyway. But in regards to going through thin epoxy. Yes since it will go through pvc insulation in the magnetic flux close by.

News flash! Tourmaline is pyroelectric. Hel-loo! Nt, posted on August 16, 2024 at 05:02:30

 Rochelle salt is supposed to be more effective, but havent tried that yet. I wonder if it will react will copper and corrode. I intend to try soon. The cheap way. Also an empty copper tube like a foot long infront of my lap top helps somewhat to dampen the rf. Held off the surface like 1/16 by glue and must have caps on ends closed up for a cavity filter. Effective enough that 2 of these in front is to many as will weaken signal. But 5 lashed together by aluminum tape staggerd underneath the laptop seems ok to help somewhat. Not a perfect solution, but cheap.
Enoch is valid !
