Oh yeah, I agree it's super inefficient currently. But if the theoretical 100% efficient process is 5% of our current yearly energy expenditure, that sounds promising and suggests we shouldn't just write off the idea.

Exactly. I want to see some investment into CO2 removal. If that's cheaper than retooling everything, we should do it. If it's not, we should do a little bit of it to help remove the negatives of climate change as we transition to a more responsible society.

I say we tax carbon emissions at around the theoretical removal cost, and then use some of that to invest in removal tech.
