When one of the richest men in the world drinks water obtained from (there’s no better way to put this) poop, you know something’s not right. Thankfully, when Bill Gates does it, it’s a good thing, because he’s doing so to test an installation, called the Janicki Omniprocessor, that takes sewage material and churns out electricity and clean drinking water. In developing countries that cannot match up to the sewage disposal levels of developed ones, this could be a revolutionary waste disposal technique.
