Sounds familiar, like Rossi’s?....................
I’m not sure of the history, but I think Parkhamov was the guy who replicated Rossi’s effect just by reading what Rossi wrote. Since Rossi isn’t really a scientist submitting his findings for peer review but more of a tinkerer trying to become a trillionaire, that is a bit like learning magic from watching a magician.
