This week UCLA scientists posted a video of their poop based biofuel project. By altering microscopic bacteria, the UCLA scientists can feed waste polypeptides to the germs, which then produce biofuels and ammonia. Unlike traditional biofuels, the end product isn’t corrosive to metal. Which, in theory, means you could just fill up your tank with the poop fuel without any special car modifications.
This might be a great way to use up the over 1 billion tons of agricultural waste produced in the U.S. every year.
