>> Bill Gates has been busy in his second life as a billionaire philanthropist.. On Tuesday in China, he took the next step in his crusade against poverty and disease by showing the room a jar of poop.>> This is a container of human feces.>> He's pointing to what the Bill and Melinda Gates Foundation sees as a big problem, bad sanitation.
As he says in developing countries there's way more of what's in the jar on the streets. They say it kills half a million children under the age of five every year, and cost the world $200 billion in healthcare costs.>> They smell terrible.>> So now he wants to reinvent the toilet.
On Tuesday he unveiled one that turns waste to fertilizer, no water required.>> The current toilet simply sends the waste away in the water. Whereas, these toilets they don't have that sewer, this is non-sewered sanitation. And 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.>> Gates looks at waterless toilets as a paradigm shift, not unlike the move to personal computing in the 70s.>> In the same way that a personal computer is sorta self-contained, not a gigantic thing, can we do this chemical processing actually at the household level?
>> Despite the surprising display, Gates may have had an eager audience in Beijing. Chinese leader Xi Jinping is promoting a three-year toilet revolution to overhaul or build tens of thousands of public washrooms.
