krebs’ cycle

Researchers at the University of Chicago are perfecting a solar-capture process that mimics closely the process of photosynthesis rather than traditional photovoltaic that converts sunlight directly into electricity. Instead, the membrane of an “artificial leaf” uses solar energy to convert atmospheric carbon-dioxide into a fuel that can be burnt. The engineers are achieving efficiencies not quite at botanical levels but at least as something comparable to the (sunk) costs of refining gasoline.
