THPOOPSSI don’t have a gross fetish or anything, but I love talking about poop. Even Laura likes busting my chops about it. Sorry, I think dookie is hilarious, but crap is also a largely untapped resource. The stinky stuff is an excellent power source. And this slideshow shows how it’s being used.

The black and white drawing explains how poop was turned into power in 1922. And nowadays, poop even can power a train, and methane from both human and animal waste makes great biogas. Actually, after I have a few beers and some bean dip, I can make great biogas too.
