Scientists at a solar thermal power plant in Germany are using the "world's largest artificial sun" as well as a large amount of solar panels to conduct research into CO2-free production of hydrogen.
Researchers at the plant in Juelich, operated by the German Aerospace Center (DLR), are using 149 Xenon short-arc lights, which together make the structure known as "Synlight," to produce a glare that is 10,000 times the intensity of the solar radiation at the Earth's surface.
