Bill Gates Awards Grants for Reinventing the Toilet

August 15th, 2012 Scott Jung News, Public Health

Last year, we wrote about a challenge that former Microsoft CEO and philanthropist Bill Gates posed to the scientific and engineering community: reinvent the toilet. According to the Bill and Melinda Gates Foundation, forty percent of people on Earth, or about 2.5 billion people, don’t have a safe and sanitary way of doing their business, so the Reinvent the Toilet Challenge was born.

The diversion-toilet. In the foot underneath the toilet bowl the containers for urine and feces and the seal against odors. Behind the water-wall with opportunities for hand-washing, anal-cleansing and cleaning the bowl. On top the transparency indicator for the level of the cleansed water. Credit: EAWAG

This week, Gates awarded grant prizes to three universities for their innovative commodes. The California Institute of Technology won first prize for their solar-powered toilet that also generates hydrogen and electricity. In second place, Loughborough University in the UK designed a toilet that produces biological charcoal, minerals, and clean water. Third place went to the University of Toronto in Canada for their toilet that sanitizes fecal matter and urine, and recovers clean water. An honorable mention was given to Eawag (Swiss Federal Institute of Aquatic Science and Technology) and EOOS, an Austrian design firm, for an innovative toilet user-interface.

Congrats to all the winners! Here’s to a less crappy world!
