those old trees of wood that give you shadow in hot days are pretty outdated, it’s time for trees 2.0!! without all that shadow and all that pesky wood!

    So years ago something similar to this was floated as a green alternative to street lamps and similar things. Basically big tubes of algae. They actually figured out how to get and store energy from the photosynthesis of the algae and use it to power a light in or above the tank. The crazy part is the efficiency of the algae at removing CO2 from the air. One tank could pull as much CO2 in one year as one tree does in it’s average lifespan. At least that’s what they reported. Course it would take a ton of maintenance and not sure what you do with the waste algae. As a method for sequestering CO2 it has merritt. Course then there’s always the thought of how much CO2 is generated from actually making one of said tanks. That I do not know but I still don’t think it’s a bad idea. Not really as a replacement of trees though. Hell even in the pictures of this bench thing there are still trees around it. You can see the trunk of a tree behind it and the some branches off to the side on the other image.

      Well, if anyone could figure out how to ferment waste algae into something tasty, it’s you, so get your thinking cap on 🌱🧑‍🔬🫙🥗

        Well the plan was to convert it to fuel alcohols for other purposes but realistically the best possible thing to do with it is dry it out and sequester it in the earth. Seeing as how that’s where all the excess CO2 is coming from. Until we can figure out a way to mass produce stuff like carbon nanotubes and similar shit out of raw plant material there’s a limit to what we could do with carbon we pull from the atmosphere without just sequestering it underground.

          Two good ideas. I wonder if it could be dried and compressed to be used as some kind of insulation?
