It's like if we took sleeping pills every time we had trouble sleeping. Having said that, I just realised I have the impression that's exactly what people do in the USA?

Cool! You missed peak covid hysteria. But, there are people that will never recover/realize. Like the type of lunatic that would subject everyone to one of these for a thanksgiving dinner in 2025.
I don't know if that's true, but it's what GP suggests to me.
This is dangerous misinformation. Like any toxic, it's the Dosis that kills
There are very powerful far UVC products available which will give you sunburn on your skin in a couple of seconds
Somebody blasting UVC in a room of people is crypto monkey level of stupid
Lots of "toxic" things are beneficial for public health. I'm sure you could poison yourself with soap but we put it in every bathroom.
Like with soap, it does not seem plausible that you could unintentionally harm yourself with far UVC lights.
The only studies i can find suggest this is an issue. For example:
https://www.mdpi.com/2076-3417/13/7/4141
The results of the study showed that far-UVC irradiation causes significant color degradation (∆E00 >5) in all the polymeric materials tested, after 290 J/cm2 radiant exposure. In addition, significant changes in mechanical properties were observed when evaluating elasticity modulus, elongation at ultimate strength, elongation at break, and tensile strength. A particularly large decrease in elongation at break (up to 26%) was observed in fiber-reinforced composite materials.
Is there anything that suggests this will turn out okay?I don't think "stop using polymers in any place where far-uvc may exist" would fly. So it's cool that we've made something that isn't going to hurt humans, but if it destroys the stuff humans depend on, not sure that works either?
I also don't think the world is going to move to UV-stable polymers for everything just to make far-UVC work (in some cases this isn't even possible). We almost always just make things more UV-resistant instead of UV-stable.
If you want to deploy UV in a specific space (think conference room or hospital ward), I don't think the problem is that hard. There are coatings you can put on top of existing plastics which protect them from UV light. However, I imagine that customer education around managing risk to plastics is going to be a key issue for UV companies if they are to succeed.
It's perfectly possible to put small data centres in city centres and pipe the heat around town, they take up very very little space and if you're consuming the heat, you don't need the noisy cooling towers (Ok maybe a little in summer).
Similarly if you stick your datacentre right next to a big nuclear power plant, nobody is even going to notice let alone care.
- You have to size your cooling towers for your hottest hour. Doing this saves you no capital costs.
- You barely have to run the fans on your cooling towers in the winter because the air is so cold. So often this also won’t save you much operating costs.
- Already there is an essentially unlimited amount of so called “waste heat” from power plants and factories. Building district heating systems is extremely capital intensive, which is why this isn’t done more.
- As a municipality it’s just a horrible idea to make the heating system of your whole city rely on a random company continuing to operate (even worse if said company is in a potential bubble). This is why most district heating systems work with power plants - they already have the government involved in ensuring their continuing operations.
