On its quest in finding new, efficient renewable energy, Scientist from Germany spearheaded a new project of crafting an artificial sun, which now considered as the world’s largest.
Synlight, an artificial sun, is the largest collection of film projector spotlights ever assembled in one room, and scientists in Germany are turning them all on at once in the pursuit of efficient and renewable energy.
The energy experiment involving the world’s “largest artificial sun” is taking place in Jülich, a town located 30 kilometres (19 miles) west of Cologne, and it was designed by scientists from the German Aerospace Cente (DLR).
Furthermore, the device features 149 industrial-grade film projector spotlights, and each one boasts roughly 4,000 times the wattage of the average light bulb.
The artificial sun can generates light that’s 10,000 times as intense as natural sunlight on Earth.
Swiveling the lamps and concentrating them on one spot can produce temperatures of around 3,500 degrees Celsius (6,332 degrees Fahrenheit), which is three times as hot as the heat generated by a blast furnace.
Scientist utilized the huge amount of energy everyday hits Earth in the form of light from our Sun. While we do already have ways to harness the Sun’s energy, such as through solar panels, much of it still remains untapped.
Proponents of the project hopes that their experiments with Synlight will illuminate ways to tap into that wasted energy.
The experiment is not without its risks and costs, however. “If you went in the room when it was switched on, you’d burn directly,” Bernard Hoffschmidt from the DLR told The Guardian.
In order to avoid the risk, the experiment will take place inside a protective radiation chamber.
This artificial sun consumes a vast amount of energy when powered up, as well – a four-hour operation eats up as much electricity as a four-person household would use in a year – so it is expensive.
“We’d need billions of tonnes of hydrogen if we wanted to drive [airplanes] and cars on CO2-free fuel,” Hoffschmidt explained. “Climate change is speeding up so we need to speed up innovation.”
