I can’t wait until they makes these no cost, low-maintenance, and self-replacing. Oh man, just think of how easy it would be to fix our climate issues!

    Current state of the art DAC plants are incredibly inefficient. Also, even if they would come with efficiency that is comparable to trees, they would still lack other positive ecological functions of trees.

      It was always going to be inefficient trying to capture something that’s 400ppm.

        Currently running an algae farm. First step is water, which holds 8x the gasous CO2 as the air it is exposed to.

          Algae make our oxygen. Biomimicry is the way to go. Or is it bioengineering? Idk

            Genetically modifying algae to be more efficient at photosynthesis would be the way to go. However, I think it was attempted many times in the last 30 years and I have not seen any breakthroughs.

              I think there could be physical solutions to maximising co2 absorption. Like a sort of vertical farming scenario - put up massive algae farms where alot of air naturally moves through.

      current state

      No state will be efficient. Burning shit in reverse takes more energy than you got out of it in the first place. It’s a physical impossibility to make an energy efficient direct carbon capture plant.
