Idiotic all the way. If aluminum can be perceived as a battery, then everything else can be. "Poop as a Battery (PaaB)" (am I the first to use this?)(no I won't DDG it).

In that sense, Bill Gatess "Reinvented Toilet" does kinda the same. People pee and poop, sewage is processed and is converted to clean water and can produce energy [0]. Thus PaaB(!?)
