A tiny black tablet could prove to be a very big deal from impoverished countries to the Pacific Crest Trail. Researchers at SLAC National Accelerator Laboratory and Stanford University have developed a tiny, Chiclet-sized device that uses solar energy to disinfect water. During lab experiments, the device killed 99.999 percent of bacteria present after just 20 minutes. Unlike boiling a pot of water which requires fuel or purifying water with an ultraviolet wand, which requires charging, the tiny tab needs only sunlight, and can be infinitely reused.
