Probably <$15/ton if you do it at scale. Here's a good primer: https://old.reddit.com/r/slatestarcodex/comments/pc0reb/an_attempted_primer_on_olivine_weathering

  This is from a preofessor in the Netherlands, 2016 He's giving lots of strategies, other than "Olivine all the things": http://arctic-news.blogspot.com/2016/07/olivine-weathering-to-capture-co2-and-counter-climate-change.html http://arctic-news.blogspot.com/2016/07/olivine-weathering-t... This is a whitepaper from that professor 2017: https://www.scirp.org/journal/paperinformation.aspx?paperid=73520 https://www.scirp.org/journal/paperinformation.aspx?paperid=... His own summarized blogpost, where he is representing the "Olivine Foundation": https://smartstones.nl/the-rate-of-olivine-weathering-an-expensive-myth/ https://smartstones.nl/the-rate-of-olivine-weathering-an-exp... So I'm thinking this is probably a good foundation to start from. How long before someone can convince the US, much less China to olivine their fields? This is not a fake problem. It's a series of problems. I have edited a previous post in the thread to concede the technical effectiveness of this solution.
