Possibly, but isn't the first question to be answered this: is it even possible to make a carbon capture device, period?<p>Other than flora and fauna, I'm not sure that humankind has actually developed a net negative carbon capture device. Have we?<p>If we have, I'd be super duper excited to see some links to examples.
Do house plants count?<p>If you want something more aggressive, I would explore growing high surface area algae in a fish tank. You can probably even make it look nice.<p>If I was going to homebrew something I would try encouraging algae growth on aquarium bio balls, probably with a nice waterfall for circulation.<p>If you could encourage algae growth on even something like this it could get you started..<p><a href="https://www.youtube.com/watch?v=iXhp3W7jhEQ" rel="nofollow">https://www.youtube.com/watch?v=iXhp3W7jhEQ</a>
