The problem is that this is a theoretical minimum, not an actual, proposed process. We’d need a way to attract CO2 to separate it from the rest of the air, and afaik that doesn’t exist. Any actual process is likely to be far less than 100% efficient, probably an order of magnitude or more less.
This is an example of a real proposal, but I have no idea how efficient it is. It would be a lot more helpful if this article provided a realistic example instead of some back-of-the-napkin math.
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.

Call me crazy but what about plants and trees?! 🤷🏼♂️
They might not be 100% efficient but it’s dirt cheap to plant them, let alone not destroy the rest we still have
That’s important too, but it doesn’t scale very quickly, and requires a lot of space (read: lifestyle changes).
