Many kinds of algae and cyanobacteria are capable to use the energy from sunlight in order to produce compounds needed for their own survival, and during that process they split water molecules and release hydrogen, which holds promise as a clean and carbon-free fuel for the future. A group of researchers found a way to… »

The energy available in sunlight is a resource we’ve only begun to really get a handle on. Current photovoltaic-cell technology, typically a semiconductor-based system, is expensive, not very efficient, and only does instant conversions from sunlight to electricity. But an artificial photosynthesis system or a photo-electrochemical cell that mimics what happens in plants could potentially… »
