Open a window?
- rufus_foreman 4y agoIt's 420 ppm outside now.
- ad404b8a372f2b9 4y agoBackground ppm is no longer at 330, so opening a window would not get you there. You would need to keep the window closed and remove more CO2 than you produce.
- batch12 4y agoFair point. I wonder if there is a big difference depending on where one lives. For instance, if one were to live in the country, surrounded by trees...
- rufus_foreman 4y agoYeah that's my question. How would I remove more CO2 than I produce. I've got the window closed, I have a few houseplants, and I am already considering getting rid of Mr. Tiddlesworth, my cat. Is there some sort of machine I can buy? Like direct air capture? I only need this in like two rooms of the house.
- ad404b8a372f2b9 4y agoI don't think so. I guess what you want is a CO2 scrubber like they had in Apollo 13, but I don't know of any consumer, room-scale, ones. Plants make basically no difference sadly, in my room it gets to 1600ppm in under an hour just from me and my cat Gazpacho, although I've admonished him for breathing so much.
- rufus_foreman 4y agoGets to like 1200 here. I think you might have a bad cat. Wasn't Apollo 13 pretty much room sized?
- OJFord 4y agoCertainly wasn't 'consumer'.
- HyperSane 4y agoI will never understand how people can just get rid of their pets.
- rufus_foreman 4y agoYou just drive it up to the country and open the door and let it free. You know? Like, run free!
- lucb1e 4y agoI really don't think they were serious.
- stuaxo 4y agoJust checked my Aranet 4, in a room no one has occupied for a few hours, it's at 497
- pfdietz 4y agoIf the window opened onto 1980, sure. I guess you could try to live in a place where the plants are photosynthesizing vigorously.
- rufus_foreman 4y agoIs that like an actual thing? Like you would have a CO2 meter somewhere and it would be down to 330 because of all the vegetation?
- pfdietz 4y agoWith no wind, a corn field in full sunlight will become CO2 limited in just 10 minutes or so.
- MobiusHorizons 4y agoThat’s fascinating. How do you know? (Research? Personal experience?)
- pfdietz 4y agoI was told that, but I can't find a link for that specific claim. However, I can find a link to some old research that shows CO2 falling during the day in low wind: https://joannenova.com.au/2013/09/plants-suck-half-the-co2-out-of-the-air-around-them-before-lunchtime-each-day/ https://joannenova.com.au/2013/09/plants-suck-half-the-co2-o...
- MobiusHorizons 4y agoThanks for digging that up. Looks very interesting.
- pfdietz 4y agoThis suggests using a greenhouse to absorb CO2 to keep the air you breath fresher. To absorb CO2 at night, plants using the CAM photosynthetic system could be used. These plants absorb CO2 at night for use during the day, storing the CO2 temporarily as malate. https://en.wikipedia.org/wiki/Crassulacean_acid_metabolism https://en.wikipedia.org/wiki/Crassulacean_acid_metabolism
