Of Course the Future of Weather Control Involves Lasers

 

The idea of artificially regulating the weather has a long and vibrant history in science fiction. But who would have guessed we'd get lasers thrown in as part of the real-world version?

That's precisely what biophotonics experts Jean-Pierre Wolf and Dr. Jerome Kasparian of the University of Geneva have proposed. Their experiments revealed that laser blasts catalyze the formation of ice and channel the path of lightning. It would appear that real life weather gods do exist, but they prefer photonic blasts to Asgardian hammers.

Wolf and Kasparian's original reason for shooting lasers at the sky was to detect aerosols. But they soon noticed that pulses of infra-red and ultraviolet lasers caused water vapor to condense into ice. This doesn't work on heavy cumulus clouds, but with cirrus clouds, as “the laser action led to a strong enhancement of the total ice particle number density in the chamber by up to a factor of 100”, the researchers write.
