I've heard there's a practical green solution to carbon capture. The units are practically maintenance free and power themselves with solar energy. This allows to deploy them on many small patches of land. The captured carbon is stored in solid organic compounds that may be used as building materials. It may sound to sci-fi to be true, but it's actually just trees.
Babe wake up, new copypasta just dropped !
Agree, carbon capture process is quite efficient now. I'm working on (pretty big) company doing Carbon Capture and Sequestration. The idea is to use empty oil&gaz reservoir to inject back carbon where it comes from. So there are several advantage:
That seems like a disaster waiting to (re) happen, what's your thoughts on that?
Density of CO2 produced vs what trees capture is massively unequal. Yes trees can, but not on any tangible scale that would ever keep up with what we are doing to the planet.
Yeah, agreed. Carbon capture won't save us, not trees nor otherwise. We have to slow down what we are doing to the planet.
Ok, but how about we do more than trees? Why are you on the internet when pre-linguistic grunting works just fine?
Yeah, it's different. I think the machine on the left is an infinite energy machine. Those will never work.
The machine on the right is a carbon capture machine which does work. But not well enough. Are fast enough to solve any of the problems that we have.
I'm fine with playing around with a carbon capture machine and seeing if we can improve it, but I would never want to rely solely on it.
I want to try a thousand solutions to the global warming problem. Including societal and government changes. Cuz you know otherwise we all die.
I mean, we already have carbon sequestration machines that are even self replicating, and require minimal, if any maitenance....
Trees and algae.
Most pollution comes from shipping, agriculture, and other large industries. Poor countries/people cannot contribute because they are barely getting by as is. Even if the entire middle class in wealthy countries magically switched to electric/public/bicycling, started recycling, stopped watering grass, etc. it would make no noticeable difference.
The idea that social changes at individual level can help with pollution comes directly from propaganda pushed by cunts who are actually killing our planet for profit. Fuck them. Don't spread their lies.
I don't. When I say social change I'm more talking about like social thinking that individuals are the problem. Sorry if that was not clear.
This is wrong, or perhaps I misundertand.
Entropy is a different concept from economic viability.
The rule of non-decreasing entropy applies to closed systems.
A carbon capture system running on solar energy on Earth (note: wind energy is converted solar energy) is not a closed system from the Earth perspective - its energy arrives from outside. It can decrease entropy on Earth. Whether it's economically viable - totally different issue.
...and I don't think the Sun gets any worse from us capturing some rays.
Also, I don't think entropy has anything to do with carbon in the atmosphere. I thought it had to do with the size of the energy packets.
The problem isn't a missing technology. it's our political and economic system.
I'm all for advancing tech but nothing is going to work until we fix our behavior. We use fossil fuels because they're profitable and allow or growth-at-all-cost economy. There's nothing for which they're the only option. Only a few things for which they're the best option; the power grid and transit aren't on that list.
Yes but no. The two actual uses of carbon capture is to remove the co2 from the air before it would happen naturally and the other is making fuel sustainable for retro or novelty vehicles. You dont have to stop selling gas cars if all the fuel they use is made with carbon capture. This makes the fuel more expensive but more sustainable. Once you have driven a 911 or skyline you will understand why someone would want to drive a gas car ;) Also, technically you are going from a higher energy fuel to lower energy so as long as you can do something with the co2 it abides by thermodynamics but the problems arise when you consider real world losses.
TLDR: carbon capture is a technology we should use after we stopped polluting to fix the earth.

Yeah, it would just give people a blank check to use more fossil fuels. It is kinda like a diabetic person who acquired the disease later in life, and still not adjusting their lifestyle because drugs mitigate the effects anyhow. And the person will keep eating unhealthy food or not exercising.
Carbon capture is problematic. If I remember the area required to reduce C02 would be the size of Georgia and the air intake would be pulling in hurricane force winds. The numbers could be off but it would be a massive project that would require to be built by probably CO2 dumping infrastructure like factories.
Personally I'd say it would be better to colonize the Pacific Ocean so algae goes in deep ocean to be a carbon sink
I've heard that's why the carbon capture is best done directly out of the machinery that creates the carbon dioxide.
the picture on the right isn't demonstrating an engine. They simply use renewable energy to power the fans that suck in the air.
Doesn't change the fact that industrial carbon capture is a scam, and most of that captured CO2 is later released back into the environment to help extract oil from old wells.

Just wait until they figure out how much carbon is captured by planting a tree.
Until the tree dies and rots or burns
Specifically replanting all the forests we cut down during the age of sail is just capturing the carbon that was released when those sailing ships rotted
If we wanted to keep the carbon captured which we captured with plants, we would have to store those plants where they are safe from rot or burn them in a (not yet invented) carbon capturing furnace
Where are we putting all this CO2?
Old oil wells, preferably in high limestone areas
