The World's Largest Artificial Sun
Photoengineer Volkman Dohmen stands in front of SynlightLet there be light! Scientists at the German Aerospace Center or DLR's Institute of Solar Research flipped the switch to turn on the world's largest artificial sun called "Synlight."
Located in Juelich, Cologne, Germany, the Synlight array is a giant honeycomb-like structure of 140 xenon short-arc lamps. When focused on a single spot, the 350-kilowatt array produces the equivalent of 10,000 times the intensity of solar radiation on the Earth's surface. That's enough to heat the target area up to 3,000 degrees Celsius (5,400 degrees Fahrenheit).
