1.5 million children die each year from preventable diseases arising from poor sanitation systems. That's why some of the world's top scientists are working to make a 21st-century toilet without links to water, energy, or sewer lines, and which costs users under $0.05 a day.
In 2011, a research team featuring several Hertz Foundation Fellows received a grant to participate in the Bill & Melinda Gates Foundation’s ‘Reinvent the Toilet Challenge’. To bring sustainable sanitation to the 2.5 billion people globally who don’t have access to safe toilets, which leads to millions of deaths each year from highly preventable diseases, this team developed a self-powered combustion toilet that transforms feces into biological charcoal (biochar), clean water, and minerals. With the support of the Fannie and John Hertz Foundation, epidemiologist Philip Eckhoff pursued a PhD in applied and computational mathematics at Princeton University, receiving his degree in 2009.
