MIT is in a twisted, propeller-capped knot this morning heralding a new discovery it says will unleash a solar revolution. However, the "revolutionary leap" inspired by photosynthesis is not on the glamorous front-end of energy collection, rather, it's related to a simple, highly efficient and inexpensive way to store that energy when the sun doesn't shine. "This is the nirvana of what we've been talking about for years," says Daniel Nocera, MIT neomaxizoomdweebie who with Matthew Kanan developed the unprecedented approach to split water into hydrogen and oxygen gases using the sun's energy. The gases can then be recombined later inside a fuel cell. The key components to the process a
