I can’t wait until they makes these no cost, low-maintenance, and self-replacing. Oh man, just think of how easy it would be to fix our climate issues!

Happy to see that nobody in the comment section seems to fall for this. I’m sure that’s representative for the global human race
But if we can pretend that we might have an idea to solve it in the future we don’t have to even pretend to do anything now!
Fuck no I hope this fail, plant trees or die
In the middle of a desert? Planting trees is good, but its not enough to save us by itself.
Fun fact: it isn’t nearly enough and is prohibitively expensive making it never feasible to be enough
It’s prohibitively expensive and inefficient, but also it’s a necessary early step in making a way to take carbon out if the carbon cycle that isn’t prohibitively expensive and inefficient.
I’m not a huge fan of this approach.
Who’s gonna pay for the build cost and maintenance? Just curious.
I was thinking how much CO2 it would take to build it and maintain it
The biggest carbon sink on the planet are oceans. We need to stop messing them up.
Too late.
The thing about oceans is they have massive amounts of inertia.
We’re still surviving on the inertia from before we fucked them up, but we’ve already fucked them up, and some of the consequences of that won’t be apparent until 50 or 100 years from now.
Same with fixing them. We won’t see the effects (or the unintended side effects) of anything we do to fix them for decades, and even then they’ll probably be unnoticeable under the effects of how much we fucked them up before trying to fix them.
Stopping is probably indeed the best option, hopefully we haven’t damaged them enough that they won’t fix themselves eventually… but that’ll take hundreds or more probably thousands of years.

Fuck this postt, this is all fiction. There are initiatives that AMERICA IS DESTROYING.
Occidental and 1PointFive can’t secure permits, let alone funding, it’s all hand waving slop.
3 fucking minutes of research is all it takes
I knew it was bullshit the moment I saw “The US is building…” and it wasn’t a concentration camp
I remember seeing something about fitting ACs for carbon capture. What ever happened with that?
Nowhere because it makes no sense. ACs aren’t directly burning fuel, nor would capturing carbon help in their operation. It’s like selling an extra unrelated device on top of an already expensive appliance. Sounds like a marketing scheme to shift responsibility to individual consumers.
Mechanical forest, because organic forest are too darn archaic
Only if there was a small pipe or “smoke stack” that could emit these in super high concentrations of CO2 where we could just pipe it straight to the ground instead of capturing it through the air. Better yet, if we find all of those sources we could even stop them producing in the first place and leaving all the carbon in the ground. 🤔
/s
There’s actually a new kind of gas turbine thermodynamic cycle that does in fact emit super-critical CO2 in a highly concentrated form that is extremely easy to collect and sequester. https://netpower.com/technology/
They’re building a 300MW facility in Texas right now. I’d say this is a really solid contender for a transitionary power generation while we stand around with our heads in the sand.
Yeah, capturing it from the source is way better than capturing from some random air. A capture rate of 90% as an addon to current coal/gas infra including cement production would buy us a ton of transition time
Well we still need to capture the excess CO2 that we’ve pumped into the air for the last 200 years.
carbon capture is always a bad idea because the energy it uses cancels out the co2 it pulls from the atmosphere
If you put it right on the exhaust of a power plant it should be good no? Or not good as in good good, but better than nothing.
No. Direct carbon capture is essentially burning fuel in reverse, and at a bare minimum requires roughly the same amount of energy as was released when you burned the fuel. Consider you have a coal power plant operating at 45% energy conversion efficiency. That means for each 1,000 kW of power produced, you actually released 2,200 kW of thermal power total burning the coal. Guess how much energy you need to completely negate the impact of the power plant? It’s much closer to that 2,200 kW number. Let’s say that it only has a thermodynamic requirement of 2000kW due to a favorable storage reaction. However, those machines aren’t 1000% efficient. Even at something like 80% efficiency (much higher than I have ever seen) that still bumps you up to needing 2500 kW, and at 50% efficiency you get to 4000 kW. So in order to run your carbon capture scheme, even in the most optimal conditions, you need more than double (and potentially quadruple) the power output of the plant you’re putting it on. Now you might say “but you could use green energy to run the carbon capture!” But you could also just replace the plant with green energy and bypass the whole problem.
Carbon capture technology is essentially just PR from fossil fuel companies and it’s a total scam the way that it’s sold to the general public. It’s like if you saw a toddler going around dumping out containers of glitter and said “We need to invest in a better vacuum cleaner to keep the house clean of all this glitter to keep up with this toddler” instead of focusing on stopping the toddler from dumping out more glitter first and worrying about the vacuuming up later. Carbon capture cannot possibly keep up with or make a meaningful dent in total CO2 concentrations until we dramatically reduce emissions. It is a thermodynamic impossibility, and it legitimately pisses me off that there are engineers working on these scams who are either too stupid to realize this or are complacent in the scams.
Unless it uses hydro, nuclear, wind, solar
It still uses the energy, and most of the time it just makes more sense to directly swap whatever you’re running to one of those cleaner energy sources instead of using more energy than it would take to run the machine that releases carbon to undo that.
And the amount of CO2 it captures is miniscule in comparison.
This technology doesn’t work. It is nothing more than a way to avoid taking the steps necessary to prevent catastrophic climate change for future and even our generations.
There is no stopping it. We will evolve through crisis, if we survive to evolve at all, which sounds silly now but won’t by the end of the century, or sooner, if we continue on the path we are on.
How about we start with using those sources instead of generating co2 we have to clean. Tht would be more effective.
Which Trump has canceled many projects of those.
so burning fossil fuels to take Carbon dioxide out of atmosphere? hmmm
We just need to put solar pannels on them!!!
They put all the trees in a tree museum.
“The Mechanical Forest” sounds like a Ray Bradbury story.
