Because the spectrum required (UV-C) to do so is harmful to humans and the environment. Putting it EVERYWHERE would cause all kinds of problems.
The article blathers on for page after page after page talking about technology is back in the '60s and '70s, an experimental technology using UV wavelengths that supposedly don’t bother humans. And systems that only point up in a room like the UV light isn’t going to get reflected into your eyeballs. I get the feeling the author doesn’t have much of a background and was really just trying to stitch a bunch of research together without really understanding most of it.
You can safely blast the shit out of central air ducts, but it doesn’t do anything for infected breathing viruses into the air sitting next to you or the people that touched the bathroom door handle.
I suspect if we see any real non biased studies come out of any of this equipment the difference will be close to within the error bar.
You’re assuming it’s not more “AI” nonsense though.
I remember back in my childhood reading all kinds of stuff about vampires, aliens and what not in articles starting pretty seriously found through search engines. So the skills to resist human or machine text generators are there, everybody had to develop those.
It’s just that the new (after 2005 or so) majority in the Web considered those skills and many others irrelevant and useless, just like the people and the culture associated with them.
It took a new kind of the same threat to make them take it seriously.
And it was in some way amazing to read something weird created by a human brain. Just like music, it has some kind of “movement”, “direction”, “structure”. “AI”-generated things in comparison to those old texts are like Ludovico Einaudi, no offense to that guy, compared to Vaughan-Williams.
Will there be any benefit to say putting it in the air duct? Like on a forced air system the main exhaust from the unit (I’m guessing it’s exhaust but that sounds wrong). I know some air filters are supposed to filter out airborne viruses and whatnot but I have no way of testing that. But I know what ultraviolet will do. And I’d have to assume sitting in the metal ductwork wouldn’t really hurt anything.
The article talks about this specifically. Far-UV (222nm) doesn’t penetrate skin or eyes and is harmless to humans. The usual UV-C used for disinfection is 254nm and is quite dangerous.
This article is a longer version of “bleach kills it fast - what if that could be brought inside the body somehow?”
Just eat a tide pod and wash it down with some bleach!
