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!

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.
Some of the carbon might return to the atmosphere via rot, but far more of it would be put into the soil or trapped in lumber. Besides, the solution is extremely cheap and effectively self replacing, just let new trees grow as old ones die.
Go look up how much CO2 is actually in the air. Then look up how much air exists in the atmosphere. Then, finally, look up how much air these things are capable of filtering out.
Then you will see why this is a scam.
Some trees can continue to grow for hundreds to thousands of years before just dying and rotting away. I don't see the carbon capture machines lasting that long without steady power and maintenance.
And when they rot away, that carbon is released back into the atmosphere. Hundreds or thousands of years isn't nearly enough, we need to take it out of the carbon cycle permanently. These particular machines will last maybe a couple of years, and will probably generate hundreds of times more carbon in their construction and maintainence than they'll sequester, but it's a necessary first step. It's not possible to put the carbon back in the ground where it belongs at a viable cost and energy expenditure without building these machines first.
One of the many problems is at least in the US, it tends to be used for fracking ….. storing it under ground to pump more oil
