In a new video on Bill Gates’s blog, the Gates Foundation co-founder sips water made from human waste using a machine called OmniProcessor, manufactured by Janicki Bioenergy in Sedro-Woolley, Washington, north of Seattle.

As he writes in a blog post:

The video is meant to raise awareness about ways to improve sanitation and access to clean drinking water worldwide. Some 2.5 billion people lack access to proper sanitation, and more than 1 billion people have to defecate outside or in public, contaminating drinking water supplies—a problem that can cause disease and death.
