German scientists create artificial sun to produce clean energy…and it is amazing! At the German Aerospace Center’s research facility in Jülich, a group of German officials and scientists have unveiled a $3.8 million system. Across a single wall in the building sit a series of Xenon short-arc lamps, spread across a surface 45 feet high and 52 feet wide, there are 140. This artificial sun meant to focus the energy of 10,000 sun-Earth radiation rays to a single 20 x 20 cm cone. Watch the video below for more info about the largest artificial sun in the world!
