(BERLIN) — Scientists in Germany flipped the switch Thursday on what's being described as "the world's largest artificial sun" and which they hope will help shed light on new ways of making climate-friendly fuel.
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.
