A winning way to deal with waste: The toilet, reinvented

A solar-powered toilet that turns urine and feces into hydrogen and electricity has won a $100,000 first prize in the Reinvent the Toilet Challenge sponsored by the Bill & Melinda Gates Foundation. The prize was announced this week at the foundation's "Reinvent the Toilet Fair" in Seattle, Washington, which continued Wednesday and showcases dozens of projects that aim to create an inexpensive and eco-friendly alternative to the flush toilet. Researchers are expected to use more than 50 gallons of soy-based synthetic feces to demonstrate their prototypes during the 2-day fair.

The flush toilet is convenient and hygienic, but the technology has its drawbacks: It uses clean water to flush away a potential source of nutrients and energy, and it's prohibitively expensive for many of the estimated 2.6 billion people who lack access to sanitation. The Gates Foundation launched its toilet challenge a year ago, funding eight projects that aimed to invent a toilet that could be operated for 5 cents per user per day while recovering salt, water, nutrients, and energy.

The winning design, developed by Michael Hoffmann of the California Institute of Technology in Pasadena and his colleagues, uses solar power to run an electrochemical reactor that breaks down human waste to produce hydrogen gas. The gas can be stored and used to run the reactor at night or on cloudy days.

The $60,000 second place prize went to M. Sohail Khan of Loughborough University in the United Kingdom. He and his colleagues developed a toilet that transforms urine and feces into biological charcoal, which can be burned, and clean water.

Third place and $40,000 went to Yu-Ling Cheng of the University of Toronto in Canada and her colleagues whose design dehydrates and smolders solid waste, sanitizing it within 24 hours.

Tove Larsen of the aquatic research institute Eawag in Dübendorf, Switzerland, Harald Gründl of the design firm EOOS in Vienna, Austria and their colleagues won a special $40,000 prize "for their outstanding design of a toilet user interface."

    The NCAA once cracked down on colleges that went too far luring top prospects, then it targeted teams that lathered players with special treatment. That was until the NCAA's get-tough approach backfired, rendering it ineffective and creating an opportunity for those who want to play dirty.

  • Has the iPad lost its swag?

      The company reported this week that sales of its sleek, pricey tablet were down 19 percent from last quarter and 9 percent year-over-year.

"This isn't something that worries us," he said of the iPad sales decline. But the numbers are disappointing no matter how you spin them.
