A Boring Dystopia

Only need half a million of them to keep up with current emissions.

For comparison, there are far fewer power plants that release co2. Based on some rough estimates I foind, there are fewer than 10,000 in total plants, most have more than one generator.

And those turn a profit, no one is going to fund half a million capture plants. Building out more solar and wind is insanely more financially prudent. N.

Over building with nuclear power with its massive capital costs makes far more sense than these things.

These solutions always remind of this scene from Futurma.

Trees do not permenantly sequester carbon, they act as a reservoir. If we cover the entire land area of the earth in amazon rainforest, it'll sequester like 150 years worth of our carbon emissions. After that, there would be no more land left to plant trees on, and we would be back to where we are now. The only solution is to simultaneously stop bringing carbon from outside the carbon cycle into the carbon cycle, and also remove the carbon that we've already brought in.

Why does this look like someone threw it together in Minecraft

It would probably take decades to offset its own carbon footprint, let alone making it negative. And then it would need to actually be significant.
Just plant trees and restore carbon sinks you fucking techno fascists.

so burning fossil fuels to take Carbon dioxide out of atmosphere? hmmm

I'm not a huge fan of this approach.

Now reunite Mythbusters and stack like 30 seconds of freeway traffic worth of cars facing it. Go.

It can't even look cool. God this timeline sucks.

Forests: are we a joke to you?

everyone seems to be jumping on how shit of an idea this is and that we just need more trees, but the point of this is that they can directly sequester the carbon back into the ground. Yes you can plant a lot of trees but when those trees die and rot away the carbon just ends up straight back in the atmosphere, you need to actually bury it to stop it re-entering the atmosphere again.

Nice, now the techbros can finally achieve their lifelong dream of paving all the forests and selling tickets for the tree museums.

After that they can plant trees on Mars.

They put all the trees in a tree museum.

If they can make like the size of 100-floor building, maybe there will be some differences rather than using trees that only occupied horizontal plane.

What would work better... Trees? Or a machine consisting of rare earth metals which need to be mined and processed and are only partially recyclable... A tree outlives a machine. Replacing old machines with new ones is good for the economy, so yeah, let's do that! Wait, what was our goal exactly?
