Scientists have created a giant laser to try to control lightning. They’ve installed the 5,000-kilogram, 9-meter-long laser on Mount Säntis, an area in the Swiss Alps that’s hit by lightning hundreds of times every year. Scientists hope that this new technology will help protect airports, skyscrapers, forests, and other places that are negatively affected by lightning.

The team is led by Jean-Pierre Wolf, a Swiss physicist who’s been working with lasers for more than 20 years and has been particularly fascinated with attempting to control the weather with them. The scientists hope to use the laser to safely guide lightning from storm clouds to areas where it won’t cause damage.

Lasers create very narrowly, high-energy beams of light. Every year, lightning starts forest fires, causes power outages, and hurts or kills people and animals all over the world. It creates billions of euros of damage, and experts predict that it will only get worse soon. Climate change is creating stronger storms, increasing the chances that lightning will hit important infrastructure.
