German scientists test 'artificial sun' for producing hydrogen

Frank Jordans reported, "Scientists in Germany flipped the switch Thursday on what's being described as "the world's largest artificial sun," a device they hope will help shed light on new ways of making climate-friendly fuels. The giant honeycomb-like setup of 149 spotlights—officially known as "Synlight"—in Juelich, about 30 kilometers (19 miles) west of Cologne, uses xenon short-arc lamps normally found in cinemas to simulate natural sunlight that's often in short supply in Germany at this time of year. (...) By focusing the entire array on a single 20-by-20 centimeter (8x8 inch) spot, scientists from the German Aerospace Center, or DLR , will be able to produce the equivalent of 10,000 times the amount of solar radiation that would normally shine on the same surface. Creating such furnace-like conditions—with temperatures of up to 3,000 degrees Celsius (5,432 Fahrenheit)—is key to testing novel ways of making hydrogen, according to Bernhard Hoffschmidt, the director of DLR's Institute for Solar Research.
