After an extensive search, the Gates Foundation has given millions to this futuristic power-generating toilet from CalTech--with the hope that it can be the solution to sanitation problems around the world.
Today is World Toilet Day. That’s not as silly as it sounds. Two and a half million people around the world don’t have access to clean toilets, which means they are at risk for a number of diseases--diarrhoeal diseases, in fact, kill someone every 20 seconds. More people die from poor sanitation than measles, malaria and HIV/AIDS combined.
