Reinvent the Toilet: Bill & Melinda Gates Foundation
"About 2.5 billion people use unsafe toilets or defecate in the open. Poor sanitation causes severe diarrhea, which kills 1.5 million children each year. Smart investments in sanitation can reduce disease, increase family incomes, keep girls in school, help preserve the environment, and enhance human dignity."
"The fair brought together people from a wide range of disciplines—inventors, designers, investors, advocates, academics, and government officials—all thinking about innovative ways to solve this long-standing problem. While at the fair, I awarded prizes to three universities we challenged a year ago to come up with solutions for capturing and processing human waste and transforming it into useful resources. The winners included: first place to California Institute of Technology in the United States for designing a solar-powered toilet that generates hydrogen and electricity, second place to Loughborough University in the United Kingdom for a toilet that produces biological charcoal, minerals, and clean water, and third place to University of Toronto in Canada for a toilet that sanitizes feces and urine and recovers resources and clean water. A special recognition was awarded to Eawag (Swiss Federal Institute of Aquatic Science and Technology) and EOOS for their outstanding design of a toilet user-interface.
Toilets are extremely important for public health, and – when you think of it – even human dignity. For most of us living in the developed world, we often don’t give them much thought...."
