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?
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’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.
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.
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
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.
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.
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?
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.
“X can kill gems! Why don’t we use X everywhere?”
X: Thing that can kill humans too. And/or cause cancer.

But what if we just inject the bleach? Or what if we just shine the light on the inside?

I always thought these were pretty cool. I’m not sure how HEV compares to UV though, or if it even works
Because it’s great at killing things, including human skin. Seriously, my local gym has people practically sign their life away before letting them into a UV-A/B tanning booth. No way are you putting the even worse UV-C bulbs out in public. That’s how people got their retinas fried at a crypto conference in Hong Kong last year.
People think I’m nuts when I wear sunglasses on cloudy days, but my eyes hurt. Idk why they don’t hurt the same way sunny days, probably I don’t squint when it’s not so sunny.
Probably the scattering effect of the clouds. Instead of light coming from one direction, which you can angle away from to reduce intensity, the diffused light from the clouds is bouncing every which way. Which while making the intensity less, instead keeps it constant no matter where you face. I often wear sunglasses while driving on cloudy days for similar reasons.
Basically, looking at direct sunlight will obviously be more damaging, but diffused light doesn’t give you a break.
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)
Who the hell thought that an NFT festival was a good idea and unprotected UV lights?
Maybe the organisers were exposed to gamma radiation lwhen they thought up the event.
i imagine theres a lot of overlap.
In Macau, they have little trash garages which are flooded with UV at night
UV light kills almost all viruses because it’s ionizing EM radiation. So it also fucks humans up, xd. I mean just stay on sunlight naked for a day. Your body will be so happy. All the mutations from ionizing radiation would be great.
But yeah we life in a society where ppl is scared of Radiofrequency EM waves (non-ionizing), “dangerous cell phone towers, wifi dangerous”. That same people recomends staying long periods of time with direct sunlight contact without protection (yeah we need protection because sunlight spectrum has UV and higher freq ionizing radiation).
Sunlight healthy/radio waves dangerous, that is the most stupid statement ever.
Sunlight is beneficial in small dosis because of how we syntetise vitamins (as little as i know). But remeber if you are scared of microwaves, remeber that sunlight has much more higher freq(higher energy) waves.
This thread might be the worst example of “I didn’t read the article, but I’ll comment anyway” that I’ve seen.
Yeah but ducks shouldn’t do that!!!
(I didn’t even read the headline)

You really dont want to live in a sterile environment, you actually need some stimulation to your immune and other bodily systems. Most body stuff is like muscles including the immune system - when you regularly over load and stress them, thats the impulse to stimulate growth and evolving.
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.
