At the " Reinvent the Toilet Fair " competition recently held in Seattle, twenty-eight designs were displayed. The winners, from the California Institute of Technology , were awarded a $ 100,000 prize by the Gates Foundation. "We couldn't be happier with the response that we've gotten," Bill Gates said at the event. Many of the new designs would not only greatly improve hygiene in the developing world, but also help change the dependence on traditional flush toilets in developed nations, he said.
