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!

    It can, but it isn’t and it won’t. DAC is a scam and a distraction until fossil fuels are out of the equation. It is a false hope, a glamour, to keep us from addressing the root causes.

      Once fossil fuels are out of the equation, we will still need to sequester carbon. And at point, it will actually be powered by renewables.

        When fossil fuels are out of the equation, civilization will have to learn to live on a roughly 3 to 1 EROEI as opposed to the 100:1 of the prewar period and the roughly 20:1 today.

        Your surplus energy decides your civilizational metabolic rate and is a key pillar of what is possible. Are we building shit like this at 3:1? What are we giving up for it?

          No, and we never will if the technology doesn’t improve. The carbon has to go, there’s no two ways about it

            The carbon, or us has to go. If we couldn’t afford to not emit it in the first place during the years of plenty, there is zero chance of getting rid of it in the lean years.

            Any carbon emitted is carbon we will have to try and live with.
