Poop as Fuel - The new future

Last month, we were in collective awe of the Bio-Bus, better known as the Poop Bus, when it made  international headlines. The 40-seat bus, which runs on biomethane gas collected from human waste, was put into service in the UK, where it now travels the Bristol-to-Bath route.

The Bio-Bus, a 40-seat mass transit vehicle that can travel 186 miles on a tank of compressed gas produced from human waste, is a lot less disgusting than you think. It may even be an ingenious, carbon-neutral way to make use of our waste.

One tank of fuel on the Bio-Bus is roughly equal to the waste produced by five people in a year’s time. The exhaust emits about 30% less carbon dioxide than the standard diesel engine of a similarly sized bus.
