If you're all about the environment, you know that renewable energy is cool. But new technology has taken a dump on gas-powered vehicles, and turned this 'cool bus' into a 'stool bus'. Who would have thought that all those jokes about powering your vehicle after a meal at your favorite Mexican restaurant would one day be a reality?

The UK's first poop-powered bus is ironically called number two, runs between Bristol Airport and Bath City Center. The Bath Bus Company gets its stool-fuel from Bristol sewage treatment works in Avonmouth.

There's even a cartoon of a man on the toilet on the side of the bus. When you're in England takin' the bus, just remember that someone was takin' a dump to get you from one stop up to the next. Hopefully there are no backups on this route and this bus's schedule is regular.
