🪭 How China Deals with the Heat

In the city of Yuncheng (Shanxi Province, China), water mist spray systems have been installed on the rooftops of residential high-rises — they create a finely dispersed cloud in the space between buildings, cooling the courtyard through evaporative cooling.

The idea is that the mist should automatically turn on during peak heat to lower temperatures in residential neighborhoods. According to some reports, the system cools the air by 5–8 degrees in just a few minutes of operation.

🔥 — Yes, absolutely!
