I’ve recently been thinking a lot about pumping CO2 out of my bedroom. By coincidence, so has Diffractor (in a slightly different context / with different goals). His post on the CO2 scrubber he built is a pretty good read, although I think he might be making a mistake about the plausibility of vacuum swing adsorption using zeolites. I wrote a comment outlining what I think is the mistake, and I guess I wanted to highlight it here in case I later want to come back and find it, and because I want more people to see it and potentially write dissenting opinions.
