Requiring nothing but abundant, non-toxic natural materials, this discovery could unlock the most potent, carbon-free energy source of all: the sun. "This is the nirvana of what we've been talking about for years," said MIT's Daniel Nocera, the Henry Dreyfus Professor of Energy at MIT and senior author of a paper describing the work in the July 31 issue of Science. "Solar power has always been a limited, far-off solution. Now we can seriously think about solar power as unlimited and soon."
Inspired by the photosynthesis performed by plants, Nocera and Matthew Kanan, a postdoctoral fellow in Nocera's lab,
have developed an unprecedented process that will allow the sun's
energy to be used to split water into hydrogen and oxygen gases. Later,
the oxygen and hydrogen may be recombined inside a fuel cell, creating
carbon-free electricity to power your house or your electric car, day or
Jay-Mah's comment: Amazing, 'yes'. But a 'real' world for the masses; or, the elite only?
