Same 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.
