    I had the same reaction until I read this.

    TL;DR: it’s 10-50x more efficient at cleaning the air and actually generates both electricity and fertiliser.

    Yes, it would be better to just get rid of all the cars generating the pollution in the first place and putting in some more trees, but there are clear advantages to this.

      I appreciate Rebecca Watson’s opinion. Watched the 6min video, now convinced 👍

      Also learned a new term: kneejerk cynicism

      How long does it take to break even from the pollution and electricity spent to make and install these?

            I mean yeah it’s a great idea but what if someone comes out with 6 minute abs?

            Step into my office.

            Why?

            Cuz you’re fucking fired!

            -pooly paraphrased from one of my favorute scenes in Something About Mary

            *bonus cuz noone asked, my favorite scene is when he asks his buddy how it’s been and his buddy says “you know each day is better than the next” without thinking it sounds like each day is great but he’s really saying is every day is worse and worse🤣

      It provides fertilizer but needs “some food”.

      How much food and what is it?

      Typically for aquariums you have to feed these things fertilizer so it seems odd

        It’s just some circle of life stuff, fertilizer, carbon dioxide, light in, The algae produces more algae. It loads up on a bunch of carbon, some of the bloom dies off, by removing it, you take the carbon with it along with some of the fertilizer components. You add a little more fertilizer in and the algae blooms more and sucks up more carbon dioxide.
