Researchers in China are looking to solve water shortages by using rain machines. To create rainfall, the machines burn a chemical fuel to produce silver iodide particles. Once it reaches the atmosphere, the silver iodide creates crystals that encourage rain clouds to form. To increase efficiency, the rainmakers will be plugged into a computer network that uses weather satellites to time the release of silver iodide during periods of cloud coverage. They are considering installing a network of machines high in the mountains of Tibet, and plan to cover an area that’s three times the size of Spain.
