Making fuel out of poop

While the idea of making use of the world's cow dung and urine does not have a really great sound, the idea that it will produce fuel is very appealing. Scientists at Obihiro University in Japan have come up with a process to produce hydrogen fuel out of cow dung and urine. They also say that this process could be applied to human waste as well.

This would definitely enable us to have some kind of free energy. Frankly, I don't know any person in this world that doesn't produce some type of poop or urine. Some people are just full of it.
