It's not us versus nature." more »
A Moment We've Been Waiting For: Stanford scientists develop water splitter that runs on ordinary AAA battery
Hongjie Dai and colleagues have developed a cheap, emissions-free device that uses a 1.5-volt battery to split water into hydrogen and oxygen. The hydrogen gas could be used to power fuel cells in zero-emissions vehicles."Using nickel and iron, which are cheap materials, we were able to make the electrocatalysts active enough to split water at room temperature with a single 1.5-volt battery," says Dai.
