Germany recently completed its enormous Synlight project. Towering three stories high, the project is the world’s largest collection of film project spotlights in a single room, and the company behind the project — the German Aerospace Center (DLR) — just switched it on.
When on, the lights create a combined intensity that’s 10,000x stronger than sun’s light on Earth’s surface and temperatures of around 5,400 degrees Fahrenheit. It’s basically the world’s largest artificial sun.
Synlight would easily fry a human, which is why no humans are allowed inside the test chambers during experiments. Watch this project melt metal and learn why Germany spent the US equivalent of around $3.7 million to build Synlight.
