PASADENA, Calif., Aug. 15 (UPI) -- The Bill & Melinda Gates Foundation said a California Institute of Technology team has won a contest to "reinvent" the flush toilet.
Bill Gates announced the Caltech team has won a $100,000 prize in the "Reinvent the Toilet Challenge" by designing a toilet that filters liquid waste through a "sun-powered electrochemical reactor" that oxidizes the chlorine in the urine and kills microorganisms, allowing the liquid to be recycled back into the toilet, The Seattle Times reported Wednesday.
