Arizona’s new heat officer said Friday that he is working with local governments and nonprofit groups to open more cooling centers and ensure homes have working air conditioners in a more unified effort to prevent another ghastly toll of heat-related deaths this summer.
Yup. Evaporative cooling was popular in AZ before electricity was available. In the late 1800s to early 1900s there were many homes and building with cooling towers on them. People would hang wet sheets across them and the cooling effect would create a current as it fell down the tower which would on turn create more draft across the cooling cloth.
