| >From Lawrence Berkeley National Laboratory, April 12, 2007: [Only registered users see links. ] "Quantum Secrets of Photosynthesis Revealed" BERKELEY, CA -Through photosynthesis, green plants and cyanobacteria are able to transfer sunlight energy to molecular reaction centers for conversion into chemical energy with nearly 100-percent efficiency. Speed is the key - the transfer of the solar energy takes place almost instantaneously so little energy is wasted as heat. How photosynthesis achieves this near instantaneous energy transfer is a long-standing mystery that may have finally been solved. Scientific American has a news summary about this research: [Only registered users see links. ] or [Only registered users see links. ] As does the journal Nature (in which the full article will be published). "Knowing how plants and bacteria harvest light for photosynthesis so efficiently could provide a clean solution to mankind's energy requirements. The secret, it seems, may be the coherent application of quantum principles....": [Only registered users see links. ] PhysicsWeb also has a piece: [Only registered users see links. ] Quite interesting.... -- Brett [Only registered users see links. ] "The 100 finest sites on the Web, all in one place!"
