Swiss breakthrough could mean rain on demand
Close up of the condensation cloud formed in the laser's wake
Article Summary
Swiss researchers have reported laser-powered cloud seeding success, both inside and outside the laboratory. Inside the lab, a powerful infrared laser caused visible clouds of vapor to follow in its wake when fired into a water-saturated chamber and sensitive weather apparatus recorded spikes in water droplet density when it was fired into the skies of Berlin, although nothing was visible to the naked eye.
