Cloud Seeding with Dry Ice
Cloud seeding with dry ice is used to create rain! Cloud seeding was discovered accidentally in a General Electric laboratory in New York. Below are several interesting cases in which cloud seeding was used:
- In 1946, GE chemist Vincent Schaefer caused a snowfall near Schenectady, NY by dumping six pounds of dry ice from an airplane.
- Cloud seeding was used by the U.S. Air Force in Vietnam to extend the monsoon season.
- The radioactive fallout from the Chernobyl nuclear disaster in Russia was contained and kept from reaching Moscow with cloud seeding.
- Cloud seeding was used in China to reduce air pollution during the 2008 Olympic Games, and it is still used in airports to remove fog.
