Researchers have developed a reactor that pulls carbon dioxide directly from the air and converts it into sustainable fuel, using sunlight as the power source.
We have this literally every winter in my area, but instead of 200km, it’s more like 20. We get what’s called an inversion where particulates get trapped in our valley, and they don’t leave until the weather changes and all that crap can escape. When it gets rally bad, I can’t see the mountains on the other side of the valley at all, whereas when it’s clear, I can make out specific features on the mountain.
During COVID, we had far fewer bad air days, because we weren’t producing nearly as many particulates.

i guess india can really use it
This reminded me of that video when the covid lockdown caused the air to be so much cleaner that a mountain range could be seen from ~200km away:

you can see it’s peak around 350 km away
