German scientists began tests on Thursday of what became known as the "largest artificial sun in the world," which consists of a device with 149 light bulbs, officially called "Synlight." Thirty kilometers west of Cologne, the equipment uses short-arc Xenon lamps commonly found in cinemas, to simulate natural sunlight, which strikes Germany in a smaller amount in winter.
By concentrating all the light bulbs and a single 20-by-20-centimeter point, German scientists will be able to generate the equivalent of 10,000 times the amount of solar radiation that would normally reach the same surface, which can reach temperatures up to 3,000 degrees centigrade. An important step in testing the conditions for hydrogen production.
Believed that hydrogen will be the fuel of the future because it does not emit carbon when burned, which means it does not interfere with global warming. Since hydrogen does not arise naturally, it must first be produced by separating water into two substances in a process that currently requires enormous amounts of energy.
