    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.

      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.
