Carbon capture is cool, I just wish it wasn't mainly being used to create hydrocarbon fuel. If only there were some way to turn carbon from the air into, say, fibers, or building materials, or food, or medicine, all using solar power... Oh well, guess we gotta build these huge machines to literally make oil out of air, that'll surely save the environment

If we want to get *really* scifi, maybe these hypothetical carbon capture machines could construct *themselves* out of captured carbon, possibly using some kind of tiny pod containing most of the materials needed to get started as well as the information to construct the entire machine... Maybe these pods could, themselves, be made through carbon capture using the same machines, making them self-replicating without any technical skills needed

But this is all some kind of absurd pipe dream, of course. It's not like self-replicating material-producing carbon capture machines grow on trees

@doppledee Maybe we could make these machines out of biodegradable materials like wood so they just decompose after they stop functioning...

@socalledunitedstates
I mean you do you, I'm here for the unconditional surrender or destruction of mankind tho so :ms_shrug_m3:

@socalledunitedstates @doppledee no they should not decompose - that would release the co2 again

@mrweb @doppledee Not if the carbon (and other materials) gets stored in the environment to help construct even more of the same machines later

(The joke is I'm describing plants in all of these posts)

@doppledee @socalledunitedstates be careful, the gray goo may diversify and evolve and eventually a subset of it might even gain sentience and make witty remarks on social media

@socalledunitedstates TBF, plants do constructive chemical reactions at temperatures way below the boiling point of water i.e. with very low energy requirements.

Not to mention, that all the high energy-storage organic compounds which we *simply burn* at extra energy expenditure and waste are also just compressed plant matter.

As Bucky Fuller once put it: Burning fossil fuel is like someone who has a three figure income discarding all of that and rather uses up their meagre savings account.

@socalledunitedstates @astrid oh my gosh! when i got to the last sentence i dropped my phone in amazement! 😍

(also glad i did not see the first post in the thread first, as that would have ruined the surprise!)

@socalledunitedstates @rabcyr there’s a multi-million dollar x-prize for “turning atmospheric carbon into useful material” and I’m so tempted to mail them a ficus and a 2x4

@cinebox @rabcyr God, that's so funny. We won't be able to make machines that are remotely as efficient as plants at any point in the knowable future. We're better off genetically engineering plants to produce a wider variety of things we need (and actually using the things they already produce)

@socalledunitedstates @rabcyr “to show the utility of this technology I have printed this report on material made of captured carbon...”

@socalledunitedstates @cinebox @rabcyr I'm not so sure. Our machines have already beaten them on light to energy.

@socalledunitedstates We actually have nano-machines that construct themselves out of carbon they capture from the atmosphere. We call them "plants".

@socalledunitedstates Only problem is, getting rid of them release the CO₂ back, so we need some way of storing them somewhere somehow...

@gcupc @socalledunitedstates Sure, now only train the plants to do it on their own and we are done.

@socalledunitedstates That's right! These machines don't grow on trees. They grow on the ground!

@socalledunitedstates you've hit the nail on the head, though. if we don't also do something about the huge dynamic range of the poverty-wealth spectrum, the people at its extents will never stop seeing freestanding, deoxidized capture matrix as fuel to be burned again.

@socalledunitedstates @janboddez and then a runaway scenario with ever more self replicating carbon capture machines, leading to too much carbon capture, abruptly bringing about the next ice age....

@socalledunitedstates @janboddez my bad. Should have read more closely. More plants....the horror! :D

@socalledunitedstates @janboddez or the machines realizing that life forms are the biggest remaining source of carbon for them to capture....

@socalledunitedstates @packbat I find it vaguely frustrating how many people missed the joke and described it right back to you

@socalledunitedstates I'm dumb, i did not pick up on the joke until halfway through
