robert murray smith on YT has a variation on this where he's basically just sticking copper electrodes and galvanized steel (in the form of bridge spikes) into the ground. apparently, soil microbes' metabolic processes provide a vehicle for electron exchange.
there's also a really cool paper from some MIT guys who added carbon black to cement (25:1 ratio cement/soot, iirc) and turned concrete into a capacitor. not sure where/how they connected the anode & cathode, though. i'll look for paper.
Believe it or not most rechargeable "torches" just have batteries inside, usually in a packet but regular batteries. Get some, no bum required, ol chap
An' 'ow we gonna charge the torches, guv'na? Plug 'em into a færie's bum?

That's wild. You've surely come across articles regarding a uranium vein in Africa that is/was able to make power? Very cool earth stuff.
i have not. links? or search terms? sounds interesting.

That's the first article Google gave me for it. I'm sure there's a more technical analysis somewhere.
