The air conditioner cools a room. China decided to cool the city, the street, and the person, all at the same time. So that is eight ways China is cooling entire cities without the air conditioners you know. And the through line connecting all of them is a single idea worth remembering. Most of the world treats heat as a private problem, something you solve one sealed room at a time. China started treating it as public infrastructure, something a city builds the way it builds roads and water lines. Now I want to hear from you. Which of these would you actually want in your own city? The mist that cools the street without getting you wet? The paint that cools a building for free? Or the little cooler around your neck? Tell me in the comments, because I read them, and the debate on the last video was better than the video.
