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.

In contrast to these high-tech commodes, the traditional toilets we know so well are clunky relics. They haven’t changed much since the 18th century and require between 1.6 and 3 gallons of water per flush and a hookup to a expensive sewage system.They are also luxuries that most communities around the world don’t have. Some 2.5 billion people lack clean, safe bathrooms; this costly sanitation problem kills nearly 1.5 million children annually.

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.
