Inside IBM's sprawling campus, James Gould gazed at the water coursing through the device he and his colleagues had constructed from the tank of an old carpet cleaner, several clear plastic CD cases, cotton-like quilt batting and lots of duct tape.
"It's a filter," he explained. "We came up with it because we're trying to clean the dirty stuff out of water so we can save people's lives. We tested it out 15 times. We added more duct tape all over. And it worked."
He suggested it could be employed in Africa and Madagascar or anywhere clean water is in short supply.
