India, March 19 -- Stanford scientists have devised a way to generate hydrogen fuel from seawater using solar power, an advance that may help pave the way for a novel sustainable source of energy.
The findings, published in the journal Proceedings of the National Academy of Sciences, demonstrate a new way of separating hydrogen and oxygen gas from salt water.
The technology could also be used for purposes beyond generating energy. Since the process also produces breathable oxygen, divers or submarines could bring devices into the ocean and generate oxygen down below without having to surface for air.
Existing water-splitting methods rely on highly purified water, which is a precious resource and costly to produce.
Theoretically, to powe...
