Water scarcity and a lack of proper sanitation are two of the main issues affecting the developing world. Bill Gates, the famous creator of Microsoft and one of the richest men in the world, is on a mission to tackle these issues. With the backing of Gates, Janicki Bioenergy has created the Omniprocessor, an ingenious machine that makes water, ash, and electricity from human waste.

This viral video explains the machine and even shows Bill drinking some of the water.
