Haotian Wang, Stanford University (IMAGE) Stanford University Caption Stanford graduate student Haotian Wang and colleagues have developed a novel water splitter that produces clean-burning hydrogen from water 24 hours a day, seven days a week. Unlike conventional water splitters, the Stanford device uses a single low-cost catalyst to generate hydrogen bubbles on one electrode and oxygen bubbles on the other. Credit Courtesy of L.A.
