@clive Before I got too excited I’d want to see a mass spec of the solution and the before/after weights of the electrodes to be sure it’s not just a normal redox reaction, and the aluminium is slowly being consumed.
I’d wager considerable money that it’s something like that going on.
@clive See my later post - it’s *tiny* amounts of power, but it’s not redox, since there’s only one electrode.
