The opening of the ski slopes is not completely in the hands of Mother Nature, and for that you can thank Dr. Ray Ringer. Ringer was not actually trying to invent a way to extend the ski season. His discovery of snowmaking is another happy accident.
Ray Ringer was working with other Canadian scientists to study the effects of rime ice on jet engines. An attempt to reproduce natural weather conditions lead to the discovery of how to make snow. The scientists were spraying water into the air of a low temperature wind tunnel right before a jet engine intake to create rime ice on the aircraft. Instead of creating ice, they kept making snow. The jet engines and the wind tunnel had to be shut down regularly to shovel away the powder. Continue reading “Slopes All Day: Invention of the Snow-making Machine”
