Bill Gates Is Reinventing The Toilet, We're Not Sh**ting You
American billionaire Bill Gates has made one of his more bizarre speeches at the opening of an expo in China, holding a jar of poo.
Gates was speaking at the World Toilet Expo, where international groups were unveiling their future loo designs.
The Bill and Melinda Gates foundation has spent $200 million developing a waterless one.
"This is non-sewered sanitation," Gates explained.
"So they take both the liquids and solids and do chemical work on it, including burning it in most cases, so that at most you have some ash that isn't smelling bad and doesn't have any disease in it."
Poor sanitation kills half a million children under the age of five annually and costs the globe more than $200 billion a year in healthcare costs and lost income.
That's why the philanthropist is investing so much time and money into it.
Host country, China is currently undergoing a three-year "toilet revolution" to build or upgrade 64,000 public toilets by 2020 to help boost tourism and economic growth.
Gates believes they're onto something big, comparing the move to waterless lavatories to developments in computing in the 1970s when he founded Microsoft.
