I made a comparison video about the ultra blacks that are freely available https://youtu.be/ElVzQ2M6vh0
Regarding VB and the MIT stuff, they are hi-tech and useful for optical applications like space telescopes.
Interestingly, the creator of Vantablack told me that there are also some export restrictions due to it's possible usefulness in stealth technology where you want to get rid of stray light.
Let me know if you have additional questions
Nevermind - it’s not even feasible
>> Typically, the lidar unit can spot things from more than 328 feet away.
>> In this case, the company said the darkest of dark BMWs would need to be about 72 feet away before the lasers and ambient light register the moving black hole.
I assume the AC has to work a little bit more during driving though.
What's most interesting about this watch is the steel/vanta combo costs the same as the solid gold version without vanta. Apparently just that small bit of vanta costs more than a large chunk of gold right now.
I wonder if there are any narrow bands that it specifically excels at compared to existing materials, and how big the difference is.
How do these materials both perform against radar?
Will we be seeing them as stealth paints on planes or satellites?
Also, i am anouncing right now my freedom to destroy any facial recognition cameras i come across. Its my fist amendment right to not be supressed with facial recognition because i am free to say anything i want, and using facial recognition is a violation of my first amendment rights.
Also, if i were to dimple an an entire plane’s body like a golf ball, and paint it with this... how stealthy would that be?
Put it this way: If you shine a flashlight at a cosmetic hand mirror, does the flashlight shine back and hit you in the eyes? Now tilt the mirror so that the flashlight doesn't blind you.
Stealth surfaces are supposed to work like a tilted mirror.
Now imagine a polished chrome golf ball. If you shine a flashlight at it, you'll still catch a bounce from the flashlight reflection, even if the surface is dimpled.
Compare the chrome golf ball's performance to an icosahedron faceted with mirrors. The faceted platonic solid is less likely to shine the flashlight back at your eyes, depending on it's angle of rotation. And a dodecahedron would perform even better.
google my friend. There are other specially formulated paints that aim to absorb the correct wavelength.
Now I’m envisioning a system where the spy drone sows down significantly and little machanized graphene “hairs” stand up all over its body to absorb any wavelengths of radar it wants to avoid...
This material absorbs every spectrum, what makes it really bad for that application.
