Ultraviolet light can kill almost all the viruses in a room. Why isn’t it everywhere?::Can special lightbulbs end the next pandemic before it starts?
Without bothering to read the article, I look forward to sunburning my retinas like im at a crypto rave.
To be fair, nobody complained about getting COVID from that event.
The article does mention the issue of safety and how to address it actually
Joke aside, looks like they’re using a higher bandwidth of light, 222nm compared to more common 254nm uv for medical uses. It doesn’t penetrate the skin or eyes sufficiently to cause damage.
But will it activate my transitions lenses so I look like a cool guy wearing sunglasses indoors?
And bleaching all materials in the room. And slowly destroying anything made of paper or plastic or wood.
What if, and hear me out,
What if…
What if… we just ran them when people weren’t in the room? 🤯
Crazy what happens when you can come up with your own thoughts instead of parroting reddit comments ad nauseam.
What if… we just ran them when people weren’t in the room?
This is already a thing in many hospitals, and has been used extensively even before covid.
And there are also UV systems that can be added to air ducts to kill off airborne pathogens as well. But they’re not cheap and not commonly used outside of medical facilities.
Won’t work in spaces where people are around all day, like offices, but it doesn’t matter. The eye and skin dangers are already addressed for the most part. The major remaing question is ozone and the VOCs it combines with.
What if, i know, crazy idea but what if you read the fucking article in question?
Ozone is a concern (it’s bad to breathe it), as is using it as a cheap way to do less proper ventilation
It also wouldn’t do much for things like COVID, where ventilation does help
Lemmy users don’t respond well to reasonable criticism or facts.
Only toxic and stupid comments allowed.
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.
This is the most informed comment in the thread where it’s clear you actually read the damn article.
Some of this does appear to be due to a widespread misunderstanding about how droplets spread disease in the medical field. It was thought that UV light far enough away to be safe would also be too far away to be effective. At least, not without additional ventilation, but ventilation itself would help reduce the spread, and we don’t do that because it’s expensive. UV would be cheap.
Research conducted during Covid corrected this scientific misunderstanding, and UV may be effective without additional ventilation. Ozone effects still need to be studied, though, as well as overall effectiveness. It might be that the additional ozone causes a few hundred additional deaths, but with the tradeoff of thousands or even millions fewer respiratory disease deaths. That would be a worthwhile tradeoff, but we don’t know what those numbers look like.
I can’t really blame people for not reading it, They take a long time to get to the point and they’re not very cohesive even once they get there.
I just read an NIH meta study on ozone and covid about half the studies aren’t very useful, as is always the case with meta studies. It seems, at least with the variant they tested that the virus is not particularly susceptible to oxidation. The one study did note that it slightly lowered It’s ability to infect which may be useful.
Thing is, ozone’s pretty rough even on healthy lungs. I think the main worry is cancer risk over time which is a real bummer.
It’s hard because we’re absolutely walking germ factors and anything strong enough to truly knock out the germs is strong enough to damage us over time.
I wonder is in 100 years will have robots in stores walking around behind us sterilizing everything we touch.
The article itself mentions solutions to the issue of it being harmful to humans, either by putting it at a distance in the ceiling or just running air ventilation through it, or choosing a specific spectrum that apparently doesn’t seem to be harmful due to being blocked by the dead cell layer of one’s skin. The environmental issue though also gets talked about, and is suggested to be more the problem.
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.
“X can kill gems! Why don’t we use X everywhere?”
X: Thing that can kill humans too. And/or cause cancer.

I’m so tired of this misrepresented quote. He said take the blood out, THEN bleach it. Covid deaths would drop overnight but y’all ain’t ready for that talk
Boy, this is the internet.
If you’re being sarcastic you better throw a /s on there because no one can tell in 2024 if your a chucklehead or if you’re high on Ivermectin.
“I see disinfectant, where it knocks it [coronavirus] out in a minute—one minute—and is there a way we can do something like that by injection inside, or almost a cleaning. Because you see it [coronavirus] gets in the lungs and it does a tremendous number on the lungs, so it’d be interesting to check that.”
There is nothing in his quote about taking taking the blood out first, he’s talking about doing the cleaning inside the body. But lets assume for a brief moment that what you say is accurate, and someone is going to take out your blood and clean it with bleach… THEN what? Now your blood is too toxic to put back in the body. Do you just kick back for a minimum of 24 hours while waiting for the chlorine to evaporate? It doesn’t work if you only take out some of the blood, because it is constantly being mixed in your body, so you have to somehow completely drain a person without them dying. Now repeat that for 8 billion people, because this process would still do nothing to protect you from getting exposed again as soon as you walk in to a store.
You might also consider how covid would have gotten into the blood in the first place – it entered the body through the lungs, and continues to grow there (which is why some many people had lung damage). So I guess while you’re killing the patient by removing all their blood, you might as well take out the lungs and bleach them too? Who here can’t hold their breath for 24+ hours? There’s just no way any of this could ever be used as a serious treatment. Yeah covid deaths would drop overnight, but only because the “treatment” would have a 100% fatality rate.
I guess the comment you are replying to was ment as a joke. But at the same time I was hoping Trump was joking, but here we are.
Unfortunately there are people who really believe this way. The same people who think Trump is some sort of god and can do no wrong.
Exactly. You can live the rest of your life without blood.
tbh I wouldn’t mind running some of my stuff through a cleansing by fire ritual once in a while
It worked for Thích Quảng Đức !
Just use sarine FFS, that’ll teach them little invisible bastards
Don’t forget bleach!

cuz it literally burns your eye holes
Might be a good idea though if you could pair it with timers/sensors so that it only turns on when people aren’t home or something.
Like a 1 hour disinfection every day while people are at work/school.
Don’t most virus just becomes useless on most surfaces after so long anyway?
I’ve got my house kitted out with quite a bit of intelligence. I’ve spent a lot of time and money getting it working right, and it still has issues with human presence among other things.
I would absolutely not trust any automated system with something like this. It’s like buying tools from harbor freight: anything that makes your life easier is fine but never buy something from harbor freight that you have to entrust your life to. Similarly, never trust an automation that has the potential to end your life.
I’m going to shill for LifX here and not get paid for it. I swear.
They already made smart bulbs that you can set a “cleaning schedule” on that uses UV light.
I don’t have any yet because LifX is expensive. I have 11 of their multicolor bulbs throughout the house, though. Bought those back when I had bachelor guy money.
I look at this the same way I look at problems I’m trying to solve at work: is this already an issue causing massive problems with how we go about our day to day operations, or is this something that might have some kind of improvement.
It’s a resource allocation issue. Sure, I can add some bulbs that kill some bacteria and viruses. But how expensive are there bulbs, and how much are we having to deal with the fallout from when someone gets sick? In the grand scheme of things, would spending ~$1,000 on light bulbs to make sure my kid doesn’t get sick (but not when in range of the bulbs…) be more beneficial than just putting that $1000 into their college savings account and learning how to deal with missing a couple days of class when the inevitable happens (which the bulb can’t protect you from anyways - you’ll get sick from other people no matter how many lights you have at home).
That thing looks terrible. t’s wifi controlled and you’re supposed to install an app to use it. And it doesn’t say anything about the UV wavelength or power (HEV=high energy visible light so I guess 9000K can be translated to wavelength). There is a pdf test report about its efficacy against a few bacteria species but nothing about aerosol viruses. I’ll pass.
Ive seen this at universities
Better idea, they turn off if you look at them and then when you look away they turn back on. Simple
Because it burns you. That’s the answer. It kills your skin cells and eyes the same way it kills the bacteria. Also, it is everywhere, it’s fucking outside. The sun. Fucking stupid. Idiots.
Know what else kills bacteria? Bleach. So get chugging.
So stupid.
We use uv light stands in the hospital. We will shut down a room and run a uv sanitizer for a bit. It works in some instances but it’s not exactly something you can just leave running all the time. Everyone would probably have a sick tan tho… To go with their skin cancer…
Those are 254nm. Far-UV is 222nm, which doesn’t penetrate or damage skin or the eyes and seems to be completely safe to humans. The main issue is that it can generate ozone, but how significant that is is currently unknown.
Ozone is also used to disinfect, that’s double the disinfection power!!!
I worked for a company that made a UVC light system for sterilization. The amount of safety you have to build in so people wont nuke themselves makes them hard to use.Also, the bulbs we used were delicate and had issues constantly.
Do you want Ultraviolet resistant viruses?
Do you want tardigrades? Because this is how you get tardigrades.
If i had a tardigrade i could fly my mushroom spaceship.
¯\_(ツ)_/¯
IDK, I kinda like tardigrades.
This thing kills all living things so why don’t we bathe ourselves in it?
I chugged cleaning chemicals. Now my insides are dirt free.
Is UV light the best thing since fermenting alcohol?
If all humans died there wouldn’t be anyone getting sick at all from anything!
I found the A.I.!!! Get’em!
This is the dumbest shit. It kills all kinds of stuff, not just bad viruses. Homes are covered in bacteria which you’ve adapted to and are helpful. Kind of like gut bacteria, but outside your body. Killing all of them isn’t a good idea.
The issue with stuff that kills everything is that… Well it kills everything.
A bit of the old Ultraviolence, eh?
Ultraviolance: solution to anything and everything (ps: this would make a very good name for a custom minigun)
Why not inject UV as a cure for all virus infections!
This way it wont reach our eyes or skin so no problems!
I always thought these were pretty cool. I’m not sure how HEV compares to UV though, or if it even works
