But I’m pretty sure this guy’s “science” was somewhat questionable. It would be interesting to track it down.

It is pretty clear the guy knew how to make batteries. Perhaps he had a method that worked.

I have to believe the source gets it wrong, since it couldn’t act as a source of electrical energy with the two conductors in direct contact. It could supply plenty of thermal energy however. Zinc melts at 787 °F, silver at 1,763°F — and the mixture doesn’t appear to be a eutectic:

I did a bit of searching on “Karl August Weinhold” but I didn’t find much. Guess I’ll have to check out the book.
