Move your butt over, Prius. Japanese toilet manufacturer Toto has a new take on a green driving machine. The Toilet Bike Neo combines a three-wheel motorcycle with a latrine. The kooky contraption runs on biogas.
Biogas is just a fancy way of saying poo power. In case you were wondering where the source of the stool is supposed to come from, the bike's built-in toilet should answer your question. It doesn't leave much to the imagination. Could we get a privacy screen, please?
