Scientists have developed pioneering technology that doubles hydrogen gas production after studying the structure of black butterfly wings.\n\nResearchers studied two swallowtails, the Heng-chun birdwing (Troides aeacus) and the Red Helen (Papilio helenus Linnaeus) butterflies, the American Chemical Society's (ACS) National Meeting, in San Diego, USA, heard. Dr Tongxiang Fan and his team at China's Shanghai Jiao Tong University studied butterfly wings to discover ways to increase the amount of useful light gathered by solar collectors.\n\nHe says, \"We realised that the solution to this problem may have been in existence for millions of years, fluttering right in front of our eyes, and that was correct. Black butterfly wings turned out to be a natural solar collector worth studying and mimicking.\"\n\nHydrogen, which is a renewable energy source, can be produced from water and sun. Developing technology can employ sunlight to increase the activity of catalysts that separate water into hydrogen and oxygen. The more powerful the solar collector, the better the technology works, says Dr Fan.\n\n- See more at: http://www.earthtimes.org/scitech/butterfly-wings-idea-boosts-hydrogen-production/1886/#sthash.a83bExkm.dpuf\nRead more at http://www.earthtimes.org/scitech/butterfly-wings-idea-boosts-hydrogen-production/1886/#sk1Cjz8tPahoJX0O.99"}
