If electricity is cheap enough, you can take CO2 from air and make fuel (not sure what is the threshold? 5-10 times cheaper then now?). then you can use that fuel where you need its energy density. I agree that it seems pretty dumb to ignore China (and soon India) CO2 emissions. Again, if you manage to make nuclear cheap enough, you could just gift reactors to everyone that needs them. It can be argued that cheap and safe nuclear was not really tried.
Well, it is quite difficult indeed, but I am curious what will happen in the next 20 years, with China very interested in this, and some renewed interest in the west too. I am also not sure which is more unrealistic, cheap nuclear or fusion.
Yea, I mean.. the point isn't the price imo. We can build out nuclear and sequester CO2 without it being super cheap. We can do massive projects like that anyway.
