    That’s only helpful after you stop burning fossil fuels, you absolute dipshits. It’s hardly a thing that exists at all, but even if we did manage to invent it it would take more energy to take a ton of carbon out of the air than is produced by burning fossil fuels that produce that ton of carbon. If you’re still using fossil fuels for energy, direct capture just makes things worse

      By some of the experimental prototypes, it’s something like 2/3 of the CO2 absorption is just the power to run it and the remaining third is removing extant CO2. People here are overly skeptical about the capabilities as a reaction to liberal media’s over enthusiasm, which prevents finding the real dunks:

      • current experimental CO2 capture uses quaternary ammonia, which smells like rotting fish and will prevent DAC systems from being installed in population centers (or at least near rich people)
      • the proposed site for this is in Wyoming, where all of those industrial emissions definitely come from
