   I hate to see things like this making the news; so-called “potato-powered lamps” or “mud-powered lamps” or whatever. The principal of these batteries is exactly that of conventional, disposable batteries; two metals of different electronegativity values are placed in an electrolyte, and electricity flows until the metal is spent. The electrolyte, whether potato, orange, lemon, mud or person, doesn’t matter a bit and certainly offers no “green cred”.

   In essence, this is a huge, wasteful disposable battery. The only “green” thing in it is the choice of LED, which is probably a practical one as such a homebrew battery wouldn’t power an incandescent bulb.
