Hydrogen gas is used to power zero-emissions fuel cell vehicles, but most hydrogen is made from fossil fuels that contribute to global warming. Stanford University Professor Hongjie Dai has developed an emissions-free electrolytic device that splits water into hydrogen and oxygen at room temperature. The device runs on an ordinary AAA battery using electrodes made of inexpensive nickel and iron. For more information see: http://dailab.stanford.edu. Support for the research was provided by the Precourt Institute of Energy and the Global Climate & Energy Project at Stanford.
