> Strebe has coated a $2 million (£1.6 million) 16.78-carat natural yellow diamond in the material Wouldn't it have been smarter to, say, make a glass replica, coat that, and pocket the $2 million diamond?

Perhaps they did and are lying about the diamond.

I think it would be cool to walk into a room painted entirely with this material. I bet it would be so disorienting that people would fall down and get vertigo. So weird.

It would just be....completely dark? I had this experience when working at a mine at one point, and if you went down one of the tunnels and switched off your headlamp.....it was absolute darkness. Like, we think that our bedroom at night is "completely dark" - but that's usually not true, that's always some source of light, after some adjustment you can see at least faintly. In an underground corridor without any lig…

I think they meant an illuminated room, but with absolutely no light being reflected by the wallls/floor/ceiling etc.

So all the visual spatial cues would be missing, despite being illuminated, like being in an infinite space. I could see how that might be disorienting and strange feeling.

An almost perfectly black and almost perfectly anechoic chamber with almost zero external sound. Peaceful or nightmarish?

The last I heard about anechoic chambers, most people can't stay in them for very long, apparently it's incredibly unsettling after a while.

I was thinking about car/plane applications. At first thought, it's "that reflects no light that's a terrible idea". Thinking further, the absolute absence of anything itself stands out from a normal background, day or night. Would be a bit interesting to see.

If you want to see something very black, look at the side of a stack of razor blades or x-acto knife blades. The individual blades are shiny, but the geometry of the stack makes it absorb almost all the light hitting it.

This is, in fact, the same principle behind how Vantablack works!

Found a small blog post about it since I was wondering what it looks like: https://erossel.wordpress.com/2015/08/24/beamdump/

Earlier quoted context omitted.

That's very interesting, I was thinking about stealth bombers. Do you think it would have applications in say, military uniforms? I wonder how it compares to digital camo, mirror based camo, etc in regards to detection.

Carbon nanotubes are similar to asbestos fibers, so it's not something that you'd want to put in a garment.

Rapidly moving lead will kill you faster than asbestos, there might be a few tactical uses for such a garment.

As will rapidly moving copper, or rapidly moving depleted uranium, or even a rapidly moving wooden stick with a stone point on it. :)

It would probably be similar to one of those sound "clean" rooms. After a while you can hear the fluids in your ear and you will feel quite uneasy.
