    anybody heard of this?

    I saw it on National geographic once where a tribe somewhere used cow crap and make batteries to charge a radio

    Would be a good science project:D

    they're doing research on this with Pig Manure batteries at a few universities & the show Invention Nation had an episode with some of the researchers

    This idea stinks.

    droll, Canadian, very droll... ;)

    The idea is simple enough, there is a permeable membrane between the section of the fluid that has certain specialized bacteria & the section that does not; the metabolic processes of the bacteria produce ions that in turn are an electrochemical potential differential causing a micro-voltage, hence... a battery.

    They sell a kit at Hobby Lobby where you can power a clock with soil.

    The Proffesor should have thought of this. The Skipper is a big dude.











    j.k.

    I could see burning it for some kind of steam powered generator, but I doubt the return on the olfactory investment would be worth the trouble for dung batteries. Maybe I'm wrong. I'm amazed at the ingenuity of people sometimes.

    Interesting. Never heard of that before, but definitely something to look into. Cow manure is abundant around here!
