Imagine stopping at a gas station, and filling your car with ... poop. Fuel made from poop may sound like science fiction, but it's already science fact. This engrossingly gross book explores the powerful possibilities. We'll discover how scientists are learning to make renewable fuels from something that most people are happy to get rid of. Unlike fossil fuels, poop is cheap, it's plentiful, and it's everywhere we are. Whether it's to the store, or all the way to Mars, poop is going places.
