    Algae does it for free all the time. Physically trying to capture carbon dioxide is dumbassery. We need more investment in algae production.

      Algae doesn’t capture it for long. Trees do it for longer but not long enough to be more then a speed bump. Unless we start dumping algae and trees into giant pits and sealing them up three is no long term carbon capture.

        Biochar (created in a retort) is how you sustainably sequester carbon for the long-term using trees (and similar biomass).

        Algae doesn’t capture it for long.

        Not true, it depends on how it’s contained. Drying algae and removing the water will stop it from decomposing. Think of seaweed used for sushi except ground up into a very dense powder. Algae will decompose if left hydrated in the sun though.

      Techbros were pitching how we’d invent self replicating carbon capture nano machines in the future

        That’s so annoying about motorsports in recent years. Commentators are tasked by the race series owners to hype up that BS. Researching the technology is fine. Scientists may find ways to capture carbon at a better rate at acceptable energy cost but shouting that an inefficient combustion engine is somehow better for the environment than EV because “batteries bad, carbon capture great” is just stupid.
