I admit I didn’t read the article throughly, but surely if it’s impossiblely thin it can’t exist. I only bring this up because I’m an obnoxious pedant.
We can make materials as thin as one atom. It’s just very expensive.
Can’t you make one atom thin sheets of carbon with a pencil and tape?
To be clear, the headline refers to yank degrees:
In outdoor tests in Arizona, the textile stayed […] 16 F (8.9 C) cooler than regular silk, a breathable fabric often used for dresses and shirts.
They didn’t really compare it to many materials it seems.
I also don’t know why they said 16+ degrees. That was the largest temperature delta they saw, not the least…
Besides, this is only part of the tale:
-
Is it affordable?
-
Is it mass manufacturable?
-
Is it comfortable?
-
Is it durable?
-
Is it washable?
-
Is it crease prone?
-
Can it be easily mixed with other materials, e.g. to make it elasticated?
-
Is it recyclable?
-
Is it dyeable?
-
is it fine for sensitive skin?
-
etc
Sounds cool (heh) though. I’m often too warm.

We prefer the term freedom units, thank you.
I prefer the term Yankee doodlegrees, thank you.
More like wank degrees, lol.

Nighthawkinlight just released a video on a material that accomplishes this that you could make at home.
So different thickness materials can actually cool you off just from a heat transfer perspective, completely ignoring the PCM capabilities (I didn’t click your link I’m just assuming it’s his latest vid). https://www.thermal-engineering.org/what-is-critical-thickness-of-insulation-critical-radius-definition/
So wearing a thin tshirt in cold weather for example can actually be colder than wearing no shirt at all. Same in reverse. I’m wondering if this material is doing that rather than being some sort of PCM.
Actual degrees or American fantasy units?
I mean, I get it that Fahrenheit is stupid, but this is an American publication.
Fahrenheit is fine for temperatures that humans can experience in our environment (and expect to survive, at least for a little while…)
I guess. But having friends from all over the planet, it becomes a pain running conversions just to have a conversation.
I mean if you need to be using precise temperature units just to have a conversation… Maybe find less particular friends?
Friend: Hey, what’s the temperature? Me: Like 74°F Friend: I don’t understand… Me: Sucks to be you! You require precise temperature units and I follow advice from randos on the internet. See ya! 👋🥴
Or, just, like,
“Pretty warm but I’m not complaining, you?”
You’re the one that brought units into it in your example. Maybe you’re the bad friend?
You want it to be true so bad. What if I’m not discussing the current location? What if I’m explaining where I’m from? We’re both in a mild, Mediterranean climate and I’m saying “oh it’s freezing back home” wtf does this mean? Are you suggesting we do away with measuring temperature at all?
I only brought “precise temperature units” into my example because you brought it up. 😒
Fahrenheit is superior to Celsius because it’s more specific and I will die on this hill. 71F feels different than 72F and yet they’re both 22C (for example).
Metric is better than imperial, though. Obviously.
Ever heard of tenths? 22.1C isn’t noticeably different than 22.2C. And yet both are 72F.
Tenths of a degree are more noticeable in Fahrenheit than in Celsius for the same reason.
The beauty of the metric system is that you can subdivide it infinitely to achieve any precision you wish. For example, you can have +22°, or +22.1°, or 22.15°, or 22.157°, etc.
A good stop-gap while cities de-car-ify and rebuild green space.
Don’t need to decarify to rebuild green spaces.
What are examples of “broadband emitter “ fabrics that I can buy? The only links I can find are for this article.
Nighthawk in light shows how to make your own on YouTube. He has lots of videos about stuff like this. Someone else in the comments linked one of his vids.
