HN 用户常推崇的硬核 DIY 范例，用极具说服力的动手实验证明了被动辐射制冷在实际中完全可行。
「关于自制高反射率涂料的绝佳视频。」HN 网友原话：Great video about making home-made high reflectivity paint
英文原摘要（HackerTube / Claude 整理）
Tech Ingredients shows how to make a homemade radiative cooling paint, with a custom liquid panel that cools below ambient temperature outdoors. The video covers the materials and how to apply the paint.
HN points to it as an impressive, hands-on DIY demonstration of passive radiative cooling that works in practice.
HN 上的提及
There's definitely something here, hopefully someone sells it pre-made, I'd love to try some.
Their latest video is on passive cooling and very impressive.
Yes, it is better than regular white paint
Great video about making home-made high reflectivity paint
they've been working on making paint using this technology with an at-home DIY process
