    The Bill and Melinda Gates Foundation has announced the winners of this year’s Reinvent the Toilet Challenge, handing over a US$100,000 first prize to the California Institute of Technology in Pasadena, for work on a solar-powered toilet (right) that recycles water and generates hydrogen and electricity

    The Reinvent the Toilet Fair brought together participants from 29 countries, including researchers, designers, investors and representatives of the communities who will ultimately use the new inventions. At the event, Loughborough University, UK, was awarded the $60,000 second-place prize for a toilet that produces biological charcoal, minerals, and clean water, while the University of Toronto in Canada won the third place prize of $40,000 for a toilet that sanitizes faeces and urine, while transforming waste products into resources and clean water.
