On GatesNotes, Bill Gates showcases the Omniprocessor, a machine by Janicki Bioenergy capable of turning human faecal matter into electricity and potable water. Mr. Gates reports that the water "tasted as good as any I’ve had out of a bottle."
I watched the piles of feces go up the conveyer belt and drop into a large bin. They made their way through the machine, getting boiled and treated. A few minutes later I took a long taste of the end result: a glass of delicious drinking water.
The occasion was a tour of a facility that burns human waste and produces water and electricity (plus a little ash). I have visited lots of similar sites, like power plants and paper mills, so when I heard about this one—it’s part of the Gates Foundation’s effort to improve sanitation in poor countries—I was eager to check it out.
