Bionic leaf turns sunlight into liquid fuel: New system surpasses efficiency of photosynthesis

Bionic leaf turns sunlight into liquid fuel: New system surpasses efficiency of photosynthesis: Scientists have created a system that uses solar energy to split water molecules and hydrogen-eating bacteria to produce liquid fuels. The system can convert solar energy to biomass with 10 percent efficiency, far above the 1 percent seen in the fastest-growing plants.
