On the hot seat: Caltech professor to speak about solar toilet

June 11. 2014

Colorado State University faculty, staff and students are invited to attend a presentation by a California Institute of Technology researcher whose team has developed a solar toilet.

Michael R. Hoffman will speak about the Bill & Melinda Gates Foundation-funded project at 11 a.m. Monday, June 16 in Engineering 120.

Hoffman and his team have created a transportable toilet that uses a solar-powered electrochemical treatment to treat domestic wastewater as well as human waste. The toilet, which can be used by up to 500 people per day, recycles water and turns waste into fuel. 

The prototypes will undergo field-testing in several locations that lack traditional urban infrastructure. Testing started in India in April.  Commercial production of the toilets is set to begin in Yixing, China later this year.

The presentation is free and open to the public. It is sponsored by the CSU Department of Chemical and Biological Engineering and the CSU Department of Atmospheric Science.
