23. Bombing the Sky to Make It Rain
In 1871, former Civil War general Edward Powers wrote War and the Weather, in which he documented several battles throughout history that were followed by rain. He theorized that the loud din of battle agitated the clouds, and caused them to release the rain stored within. Powers’ idea gave birth to what came to be known as “Concussion Theory”, which held that clouds could be forced to yield rain via loud noises.
As Powers put it: “If lightning and thunder and rain have been brought on by the agency of man, when bloodshed and slaughter were only intended, this surely can be done without these latter concomitants“. Credible scientists and scholars scoffed at the idea, but two decades later Senator Charles B. Farwell of Illinois read Powers’ book, and decided to test Concussion Theory. So he got Congress to appropriate $10,000 to make the tests.
