HN points to it as a practical, well-researched DIY demonstration of passive radiative cooling.
NightHawkInLight shows how to make ultra-white radiative paint that cools surfaces below ambient temperature without electricity. He walks through the research papers and the household-materials process.
“This YouTuber[0] does an excellent job recreating chemistry research from papers and improving on the techniques to be accomplished with household materials.” (HN, 2023)
This YouTuber[0] does an excellent job recreating chemistry research from papers and improving on the techniques to be accomplished with household materials. He documents his failures and takes an empirical approach to arriving at his successes. I’m not sure of his background, but it’s certainly research that he’s doing. Watching his channel always reminds me that the scientific method does not have “first obtain an expensive degree” as one of its steps. [0] [this video]
Recreates chemistry research from papers using household materials
Two YouTube researchers[0][1] (they make science content that is very much not in the traditional form of YouTube) have been working on Infrared Cooling Paint for almost a year now and have been detailing how individuals can make it at home (although a fairly involved/lengthy process today.) There's definitely something here, hopefully someone sells it pre-made, I'd love to try some. [0] [this video] [1] [link]
It's a thing in from thousands of years ago [link] and today [link] for PDRC there are a couple good videos about it from NightHawkInLight [this video] , [link] and Tech Ingredients [link] [link]
DIY radiative cooling paint from YouTuber NightHawkInLight - [this video] It has pretty impressive performance. Tech Ingredients did one or two vids as well - [link] Was thinking of whipping up a batch for my rv.
DIY radiative cooling paint with impressive performance
And for a better effect they could use paint that can cool below the ambient temperature by radiating infrared to space (if they aren't already using that, but it's probably more expensive): [link] Here is a YouTuber trying to making such paint: [this video] Another article: [link]
