"The whole process was a little experimental and I uncovered it as a side-effect of a completely different area of study. My main goal was to tune two crystals so they can be paired and respond to each other.

I have noticed that when I removed one of them from the tuning apparatus but not the other the zinc rod that was part of it got thinner the longer I kept the single crystal in place and the steel one developed a thin but uniform layer of zinc on it. I already knew that zinc is resistant to damaging effect of sea water so the rest was just extrapolation."

It was a toy project that he got bored with very quickly so there was not much development after those initial attempts. Especially, that the crystal used in the process had to be retuned after each one.
