I'm deeply offended on a cosmic level by the concept of boxing up a small area, heating it up from freezing, and then cooling it back down to freezing in a smaller area. Just seems like such a waste.

mahershalalhashbaz posted:they absorb microplastics and other pollutants, which mostly show up in their foliage and other green bits. once a tree is fully grown nothing eats its mature leaves much (bugs and birds prefer the fresh shoots), so at least the particles just stay there until the leaf falls off. then they're back in the soil. i am sure there's some denaturing and weathering that occurs from the leaf's processes working on the phthalates or whatever the hell is going on, not enough to totally remove the harm but something would happen. nobody has studied how microplastics get recycled through the trophic network or what happens to them over time, we only know enough to know they're there and they're causing problems. bioremediation is going to be a big field in about 5 years, with mostly disastrous results Speaking of pollution remediation - Have you seen the paul stamets work with osyter mushrooms and crude oil contaminated substrate? https://paulstamets.com/mycorestoration/the-petroleum-problem Super curious to see this get repeated/tested/etc with microplastics. Paul asks it himself - do the oyster mushrooms fully break down the oil?

This is all the poo poo that helps me really deal with my depression btw - clinical and climate change induced. There's so much poo poo you can do in your local area that doesn't involve worrying about what some dipshit moron loving politicians are doing. Find plants that are local to your area to plant and feed the local wildlife. Reintroduce plants that have been killed off because dumb rear end land developers didn't want to replant them and once they are bigger you can spread them far and wide for free or you could make money selling shoots and poo poo on etsy. Whatever. Or just give them to goons. I got my fig tree from a goon

even if we were to stop all carbon emission now, right now, we would still be locked in for a whole lot of global warming due to all the carbon dioxide and other greenhouse gases already released into the world

Carbon capture is dumb for all kinds of reasons, but thermodynamically, the energy needed to capture CO2 emissions is A.) unrelated to the energy released by oxidizing the hydrocarbons and B.) not necessarily large, at least on fundamental grounds. Even in the (maximally stupid) case of direct air carbon capture, where you are attempting to separate out CO2 after it's been diluted into the ambient atmosphere, the fundamental thermodynamic energy required to do so is related to the free energy of mixing, which is small. I bring this up because, arguing from simple thermodynamic grounds, it is easy to make a "good" argument for carbon capture, and its advocates do exactly this. This masks the (very big) actual problems with carbon capture such as: -Energy requirements being often much higher than the simple thermodynamic limit, due to practical and engineering considerations -The impossibility of implementing direct air capture at the necessary scale within the needed time -Carbon capture "at the source" being impossible for transportation, and impractical for residential heating together which account for ~half of all use -Engineering and geological limitations to sequestration, and the consequences of failure -Costs as compared to alternatives like wind, solar, nuclear -The implicit continuance of fossil fuel subsidies to make any such scheme workable -The inherent problems arising from continued extraction and exploitation of fossil fuels, even if some of the carbon is neutralized -That the entire scheme is often put forward in bad faith as a fig leaf over a "do nothing" strategy

lol the D&D thread gets hype for weird modding so I checked and I see they're having a discussion about market forces which have always externalized ecosystem cost maybe, possibly not doing that lol. people go 'bwahhhh capitalism' but really don't understand how capitalist principles being universalized will always undermine any effort.

Marenghi posted:If carbon capture worked so well, why did none of those clean coal power plants succeed? I used to design amine based carbon capture units for a living. Flue gas capture is tricky because it's at low pressure; capturing 95% of the CO2 from the flue gas will consume about 30% of the power plants energy production. However, compared to atmospheric carbon capture, flue gas capture is a loving walk in the park. It's another way to think about how dumb direct air capture is. If we can't even get capturing CO2 from our power plants to work under capitalism, how the gently caress are we going to get DAC to work when you're dealing with orders of magnitude lower CO2 partial pressure (which directly correlates to ease/difficulty of capture)?

When atmospheric carbon hits a million ppm, carbon capture will be easy. Just open a box and then close it again and pop it in a ditch

this was the song that broke my brain and make me start viewing every individually wrapped snack package as oil. millions of years of heat and pressure, creating a fluid that's a super-dense form of pure energy, pumped out of the ground in less than 20% of a millennium so that our gummy snacks would remain fresh and chewy and not get all dried out or stick together. thanks josh tillman i really appreciate not being able to view anything in these terms anymore, seeing the entire world as the stupidest waste of energy that will ever be

I don't know if this was posted in the thread, but it was an interesting video: https://www.youtube.com/watch?v=hX2aZUav-54 basically, the natural gas industry realized that the only thing that people even vaguely liked about natural gas was gas stoves, so they have a whole push to promote gas stoves to ensure that the gas infrastructure gets built into new buildings and lets people use natural gas heating/water heaters

Do you happen to have any links or papers showing what you mentioned re: the thermodynamics? Yeah, here is one for example: https://www.sciencedirect.com/science/article/abs/pii/S0360544212006901?via%3Dihub Like I said, very fundamental thermodynamic argument are often put forth in advocacy of direct air capture or similar projects...because from a very basic thermodynamic standpoint there isn't necessarily anything wrong with it--the problems (as with many or most things) are more complicated. At the end of the day, the problem amounts to taking one mixture of gases, (mostly N2 and O2, some Ar and H2O, and ~0.4% CO2), and ending up with two gases--one CO2, and the other a mixture of everything that remains. Or more generally, the end state is two mixtures, one enriched in CO2 and one depleted in CO2. Since there are no significant chemical reactions going on between the various constituents, the change in starting energy and final energy arise purely from entropic terms, which for dilute mixtures will scale something like RT ln (P) where P is the partial pressure ratio https://en.wikipedia.org/wiki/Entropy_of_mixing The energy released from, say, CH4 + O2 -> 2H2O + CO2, has nothing to do with the energy of de-mixing CO2 + N2. This is all kind of interesting when thinking about the theoretical barriers to DACC, but the real problems have practically nothing to do with the thermodynamic cycle efficiency and a lot to do with...everything else.
