Looks like this guy really wants to build a vapor core reactor, but hasn't found a suitable problem it would solve.
If turning CO2 into graphite was a viable idea at all (it isn't, but that's besides the point), doing it purely thermally still wouldn't make sense. Even if the machines made of unobtainium existed, the dissociated gasses would just recombine when cooled down. It's much easier to operate at "low" temperature (say 1200K instead of 4000K, which is still a challenge!) and do it in multiple steps. But that is casually dismissed as slow and expensive in the article---I suspect, because it wouldn't need a vapor core reactor.
- jleahy 7y agoTo be fair, when the dissociated gases recombined they would now likely have captured some neutrons, so it wouldn't be entirely without effect. You'd likely end up emitting a lot of C-14 monoxide, which fantastically is both poisonous and radioactive. I agree with a previous poster that the water electrolysis followed by the Bosch reaction would be a much more sensible approach. Of course it's unlikely that anybody will bother.
