Swiss researchers try to make it rain with lasers

formaggio writes Last year, a team of researchers at the University of Geneva in Switzerland came with an interesting way to make it rain by firing lasers in the sky. At the time it seemed that science fiction, but now they are one more step after the team has successfully completed testing around Lake Geneva From the article:. ‘Records from 133 hours of fire revealed that intense pulses of laser light creates nitric acid particles in the air that acted like glue to the atmosphere, water molecules link together into droplets and prevention. them to re-evaporation Within seconds, the drops became stable within a few thousandths of a millimeter in diameter. too small to fall as rain, but large enough to encourage scientists to build on the work
