Radio Psychedelica

It should be possible to;
Use an electroplating rig to remove solder from old circuit boards, freeing up the components without heat and nasty solder fumes. Or perhaps a bath of dilute sulfuric acid, and an extra electrode?
Using the Pb + H2SO4 = PbSO4 + H2 + 2e reaction to generate (miniscule) amounts of power, and to recycle the parts.
Will dilute H2SO4 eat PCB material?
Will have to try this one out. Even if it doesn't work, the idea of spending an afternoon with Oil of Vitriol and Lead
sends a tingle right through my Mad Scientisty bits.

woooo chemical formulae. Brings me right back to my misspent youth. Ah, the smell of burning eyebrows...
