Professor M. Sohail from Loughborough University 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.
