Germans switch on 'largest artificial sun'....(PHOTOS)

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.
The Synlight experiment in J├╝lich, 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.
