some cosiderations

[FrancoItaly]

Hi J Player
Your scientific reasonings are always interesting and appropriated!

Seden I have a old geophysicist handbook (italian, years 1953) " the electronic dowser" but in spite of title it's a technical handbook.
It deals of Spontaneous Polarization and also of Oxide Reduction battery that it works with one metal that it lies in two different ambients.

Best wishes
