Bill Gates, co-founder of the the Bill & Melinda Gates Foundation, checks out a toilet demo at the Reinvent the Toilet Fair in Seattle, Wash. The festival featured prototypes of high-tech toilets developed by researchers around the world.
Harnessing Energy Through Scientific Leaps and Bounds
A team from the California Institute of Technology, lead by environmental engineer Michael Hoffmann, created a solar-powered toilet that produces hydrogen and electricity.

A group from Loughborough University in the U.K. built a toilet that uses energy from the feces to decompose the waste and recover clean water.
And chemical engineers from University of Toronto invented a toilet which sanitizes waste within 24 hours by dehydration and smoldering.
Over the past two years, the Bill and Melinda Gates Foundation has invested nearly $150 million into improving global sanitation, Carl Hensman, a program officer at The Gates Foundation, tells Shots.
The next step, Hensman says, is to take the top-performing technologies at the Reinvent the Toilet Fair and start making larger scale pilots. The foundation’s goal is to have one of these super toilets up and running in a community by the end of 2014 or 2015.
