New system surpasses efficiency of photosynthesis. Prof Nocera, and Prof Silver of Harvard University, have co-created a system that uses solar energy to split water molecules and hydrogen-eating bacteria to produce liquid fuels. “This is a true artificial photosynthesis system,” Nocera said. “Before, people were using artificial photosynthesis for water-splitting, but this is a true A-to-Z system, and we’ve gone well over the efficiency of photosynthesis in nature.”

While the study shows the system can be used to generate usable fuels, its potential doesn’t end there...
