Scientists in Germany flipped the switch Thursday on what\u2019s being described as \u201cthe world\u2019s largest artificial sun\u201d and which they hope will help shed light on new ways of making climate-friendly fuel.<\/p>\n

The giant honeycomb-like setup of 149 spotlights \u2014 officially known as \u201cSynlight\u201d \u2014 in Juelich, about 30 kilometers (19 miles) west of Cologne, uses xenon short-arc lamps normally found in cinemas to simulate natural sunlight that\u2019s often in short supply in Germany at this time of year.<\/p>\n
By focusing the entire array on a single 20-by-20 centimeter (8×8 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.<\/p>\n
Creating such furnace-like conditions \u2014 with temperatures of up to 3,000 degrees Celsius (5,432 Fahrenheit) \u2014 is key to testing novel ways of making hydrogen, according to Bernhard Hoffschmidt, the director of DLR\u2019s Institute for Solar Research.<\/p>\n
Many consider hydrogen to be the fuel of the future because it produces no carbon emissions when burned, meaning it doesn\u2019t add to global warming. But since hydrogen doesn\u2019t occur naturally, it first has to be made by splitting water into its two components \u2014 the other being oxygen \u2014 in a process that currently requires large amounts of electricity.<\/p>\n
Researchers hope to bypass the electricity stage by tapping into the enormous amount of energy that reaches Earth in the form of light from the sun.<\/p>\n
Hoffschmidt said the dazzling display is designed to take experiments done in smaller labs to the next level, adding that once researchers have mastered hydrogen-making techniques with Synlight\u2019s 350-kilowatt array, the process can be scaled up ten-fold on the way to reaching a level fit for industry.<\/p>\n
The goal is to eventually use actual sunlight rather than the artificial light produced at the Juelich experiment, which requires as much electricity in four hours as a four-person household would use in a year.<\/p>\n
Hoffschmidt conceded that hydrogen isn\u2019t without its problems \u2014 for one thing it\u2019s incredibly volatile \u2014 but by combining it with carbon monoxide produced from renewable sources, scientists would, for example, be able to make eco-friendly kerosene for the aviation industry.\u2014AP<\/p>\n","protected":false},"excerpt":{"rendered":"
