U.S. researchers are reporting breakthroughs in artificial photosynthesis that could result in a new source of renewable liquid fuels for cars, ships and planes. Renewable liquid fuels would be a welcome alternative to electricity for powering vehicles, because batteries are heavier than fuel and take up more space, which can work for cars but makes them impractical for planes or ships. Artificial photosynthesis seeks to mimic the action of plants in capturing energy from the sun to produce biomass by breaking down water and combining it with carbon dioxide. A team of scientists from the Lawrence Berkeley National Laboratory and the University of California-Berkeley in April reported...
