00:00China demonstrates large-scale evaporative mist cooling systems operating across city streets,
00:05highways, and public spaces to reduce extreme heat. Fine water droplets are sprayed from
00:10rooftops, roadside poles, and dedicated misting units, cooling the surrounding air through rapid
00:16evaporation by an estimated 3 to 6 degrees Celsius. The deployment appears to prioritize
00:22high-traffic urban areas where heat stress is greatest, although implementation is managed
00:27at the city level rather than through a single nationwide system.
