When Kurt Vonnegut was working as a PR flak at General Electric, his older brother Bernard was a famous scientist. And Kurt was there when Bernard demonstrated his incredible new invention: a way to seed clouds with dry ice and silver iodide and make it rain. Could this be used as a weapon?

At the time, Bernard Vonnegut really believed that we had the means to control the weather and reshape the climate. And the U.S. military was very interested in using this to attack enemy forces by redirecting hurricanes and other natural disasters towards them. It wasn’t until later that we discovered cloud-seeding was much less powerful than Bernard had believed


But this dramatic demonstration had a powerful effect on Kurt Vonnegut, as author Ginger Strand explains to the Geek’s Guide to the Galaxy podcast. Vonnegut believed he was seeing a science-fictional scenario coming to life—weather manipulation, along with weather-based weapons! Strand has written a new book about this time in the author’s life, called The Brothers Vonnegut: Science and Fiction in the House of Magic.
