I think putting carbon in the ground is the wrong approach. We need to take it out the the air, yes. But then we should build things out of it. Replace steel

I think putting carbon in the ground is the wrong approach. We need to take it out the the air, yes. But then we should build things out of it. Replace steel and concrete with carbon. Imagine a rocket made out of 90% air harvested materials.
- honkhonkpants 10y agoIt doesn't make a difference to the amount of energy required. The scale of the problem is the integral of all human energy consumption over all time. We need to reverse it, and the reverse process will require much more energy than was released by the forward process, and we need to do in a few years what was done over 200 years. Whether we put it into the ground or into carbon ingots is immaterial.
