Let There Be Light: Germans Switch on 'Largest Artificial Sun'
German scientists are switching on "the world's largest artificial sun" in the hope that intense light sources can be used to generate climate-friendly fuel. From a report: The Synlight experiment in Julich, about 19 miles west of Cologne, consists 149 souped-up film projector spotlights and produces light about 10,000 times the intensity of natural sunlight on Earth. When all the lamps are swivelled to concentrate light on a single spot, the instrument can generate temperatures of around 3,500C -- around two to three times the temperature of a blast furnace. "If you went in the room when it was switched on, you'd burn directly," said Prof Bernard Hoffschmidt, a research director at the German Aerospace Center, where the experiment is housed in a protective radiation chamber. The aim of the experiment is to come up with the optimal setup for concentrating natural sunlight to power a reaction to produce hydrogen fuel.Read more of this story at Slashdot.
