Sanitation is a serious issue in many countries.

The number one killer of children in the world is disease caused by contact with feces.

Toilets, or lack of toilets, are a big part of the problem. Many third-world countries don't have them and current models are not efficient.

Bill Gates wants to fix that. He called for a Reinvent The Toilet challenge and several universities submitted designs.
