I don't want to stop anyone from debating the merits of using plants for carbon sequestration. But the ones explaining why my article did such a bad job of explaining those merits are kind of eye-opening, yes.
- tito 2mo agoSame here, I wonder if there’s some missing conversation in the hacker news community about climate. Seems like some people really wanna talk about it even off topic. I get to spend plenty of time working on climate already, so I was particularly interested in the indoor air pieces. Someone below suggested there’s a ventilation system alternative. I wonder what you could do with a little miniaturized direct air capture machine. Probably crazy energy inefficient and whatnot, but maybe a cool experiment.
- jonahbenton 2mo agoLong ago I ordered an indoor algae system from a couple of CMU PhDs. It is very cool, it looks cool and has a nice water flow backgroundy sound, the algae grows quickly, allegedly doing the co2 consumption equivalent of 20 houseplants. Space efficient! But immaterial relative to human co2 production.
- tito 2mo agoIf it was circa 2010 I think I remember those guys. It was partly for people who wanted fresh algae smoothies? How big a tank do you need to remove 1 kg of CO2 per day…
