Billionaire Microsoft founder Bill Gates has unveiled a futuristic toilet that doesn’t need water or sewers and uses chemicals to turn human waste into fertilizer. The mega-rich philanthropist is known for this potty-minded obsession with all things lavatorial, having famously swigged ‘poo water’ to prove sewage could be turned into drinkable H2O. The toilet is about to go on sale and is the brainchild of research projects funded by the Bill and Melinda Gates Foundation, the world’s biggest private philanthropy organisation. When Gates announced the new loo on Twitter, he admitted he ‘loved’ discussing toilets.
There are few things I love talking about more than toilets. pic.twitter.com/rQdY3ZiIpC — Bill Gates (@BillGates) November 5, 2018 Which might sound strange until you hear that poor sanitation kills half a million children under the age of five annually and costs the globe over $200 billion a year in healthcare costs and lost income, according to the foundation. There are multiple designs of the new toilet, but all work by separating liquid and solid waste. ‘The current toilet simply sends the waste away in the water, whereas these toilets don’t have the sewer,’ Gates said. ‘They take both the liquids and solids and do chemical work on it, including burning it in most cases.’ He compared the change from traditional toilets to waterless models as similar to development in computing around the time he founded Microsoft in the mid-1970s.
