Scientists Test the World’s Largest “Artificial Sun”

Scientists in Germany flipped the switch 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.

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.
