Bionic Leaf Uses Bacteria To Convert Solar Energy Into Liquid Fuel

From Science 2.0:  Harvesting sunlight is old technology for plants but it's a level of efficiency in solar energy we would love to be within a billion years of - artificial photosynthesis is needed if we want to go beyond the energy density of things like combustion engines. 
 
Solar energy, using electricity from photovoltaic cells to yield hydrogen that can be later used in fuel cells, would be terrific but has technological obstacles.  Now scientists have created a system that uses bacteria to convert solar energy into a liquid fuel. Their work integrates an "artificial leaf," which uses a catalyst to make sunlight split water into hydrogen and oxygen, with a bacterium engineered to convert carbon dioxide plus hydrogen into the liquid fuel isopropanol. 
 
Pamela Silver, the Elliott T. and Onie H. Adams Professor of Biochemistry and Systems Biology at HMS and an author of the paper, calls the system a bionic leaf, a nod to the artificial leaf invented by the paper's senior author, Daniel Nocera, the Patterson Rockwood Professor of Energy at Harvard University.

US Battery - Solar RE L16XC Renewable Energy Battery

Our batteries have Xtreme thick plates with (XC Diamond Plate Technology) added to them. They have been designed for hours of heavy discharge each day, followed by a fast recharge during the daylight hours. Very few batteries can take the grueling deep discharge-recharge cycle every day for long periods of time. U.S. Battery has proven time and time again that our solar battery line can stand up to this type of battery torture day in and day out for years to come. When you demand reliable energy storage count on U.S. Battery every time!
