Reinvent the Toilet Challenge: Eawag/EOOS | Bill & Melinda Gates Foundation

Tove A. Larsen from Eawag (Swiss Federal Institute of Aquatic Science and Technology) talks about their prototype for the "Reinvent the Toilet Challenge." In 2011, the Gates Foundation issued this challenge to create a toilet without piped-in water, a sewer connection, or outside electricity—all for less than 5 cents a day.

The eight finalists attended the "Reinvent the Toilet Fair" to showcase working prototypes of their entries. Finalists include innovations such as a solar-powered toilet that generates cooking gas, a toilet that turns human waste into biological charcoal, and a toilet that turns waste into electricity.
