  • Coal plant burns coal to heat water, makes steam, and the steam powers a turbine to produce electricity. A nuclear power plant uses nuclear fuel to heat water and produce steam similar to a coal plant. It may do this indirectly (e.g. second loop between the nuclear fuel and water loop to prevent the water becoming radioactive). This means that to build a nuclear plant you essentially need to build a coal plant, and then also the nuclear reactor and safety stuff, which makes them more expensive. Since coal plants are being turned off anyways, it might be more cost effective to just retrofit old coal plants so the only cost is the nuclear reactor side of things (plus any necessary maintenance and upgrades)


  • Also if you want a domain but dont care about the actual address, a .xyz domain composed entirely of numbers with less than 10 digits is $1-2 + same as renewal fee per year. $1.22 for me on porkbun

    Just be sure to redact the whois information bc you will get a call from scammers trying to get you to register your domain on some “internet map” for a small fee acting as if its some step in your setup process you havent done yet




  • I got a cheap pair of the orangest non-prescription glasses I could find that weren’t straight sunglasses and it took me from crushing headaches when I get home from work to mild discomfort by the end of the day. The only problem is they can make color perception a bit difficult (greens/blues, yellows/whites), but it’s workable for the most part. My eyes adjusted and I can still tell apart most things and anything that I can’t, I can take a quick glance w/o them. One thing to keep in mind though: they reflect blue light so you might want ones with blinders / wear normal sunglasses if you’re outside, since having the sun behind you can reflect it right into your eyes. They look a bit goofy but I’d take looking goofy over physical pain

    There are also orange clip ons that can go on existing glasses. If they have this kind of coating for prescription lenses though, I’d definitely get them

    Also cuts blinding blue headlights from incoming traffic

    Oil is placed on the pan and then it is heated to form a non-stick coating. This layer can have small holes in it, so the process is repeated many times. The holes do not line up, which makes the path for water to get through much longer or blocks it. This means water can not easily make it through all of the layers. That also means any water that gets in can’t easily get out, and it can cause rust to form if it makes it through the coating and is left on there.

    P. pruinosus could be defined as a macroconcentrator of Cd, Zn, and Cu (BAF > 2) and as a deconcentrator of Pb (BAF < 1).

    Since isopods are food source of vertebrate and invertebrate predators, one threat is the transfer and potential accumulation of these contaminants at higher trophic levels. In a regional assessment of the Greater Washington-Baltimore Metropolitan area, Pouyat et al. (2015b) found a positive correlation between lead concentration of soil, isopod body, and blood of American robin (Turdusmigratorius Linnaeus, 1766) nestlings from the same residential yards.

    One way is just by keeping the heavy metals (Hg, Cu, Zn, Cd, etc) in their body. Any heavy metals they uptake will remain in their body, and while they’re alive they create more isopods to uptake more metal. But, if they get eaten it can accumulate in other animals or if they die it just returns to the soil. They’re also useful as indicators of soil contamination.
