    That amount sounds like total bullshit. Diamonds can be manufactured and once that is done at scale, it won’t be all that expensive. Even at $10000 a ton, five million tonnes would cost just 50 billion.

      These are not good ideas. Remember that global warming is just an overarching effect of pollution which we will still have. What diamond dust pollution effects will be, no one knows, but I doubt we want to find out.

        The fossil fuel oligarchy would prefer to give all mammals on Earth emphysema than stop burning fossils, and do it for 10x the price.

      That number is for doing it anually for 65 years. It lists roughly 18 billion per year for the cost.

      But besides that, I think you are greatly underestimating the cost of the diamonds. Synthetic ones are way cheaper than natural ones, yes, but there’s a lot of room between “natural diamond expensive” and “actually cheap”. Going by these prices https://www.diamondtech.com/products/categories/diamond_powder_price_list.html

      It’s $2.5 million per tonne. I assume you could get a cheaper price per weight if you’re buying five million tonnes of anything, but it’s still two orders of magnitude more expensive than you are guessing

      Firstly, it’s 5 million tonnes per year. For 65 years. Secondly, the cost is for a 65 year SAI program, including developing the tech and running the missions. Thirdly, this is all explained in TFA or the links therein.

      $10000/ton is $5/lb from a quick google search they are about $250/lb for industrial diamonds. So 50* 50 or 2500 billion or 2.5 trillion with no idea if they can use run of the mill industrial diamonds or if there will be additional processing to get them into the aerosolized form also how are you going to launch them, and for how many years would we need to do it
