I've heard this response and it still doesn't make sense to me. If I get caught downloading a movie, it's not a defence to point to the ripper and say "I didn't violate the copyright, they did!"
This might be the first feature driven upgrade cycle that I can see people really wanting. This isn't an incremental update to an existing thing. This is a whole new thing that brings hype wagon to the masses in a probably the best integrated into daily use I've seen pitched.
Water plus carbon dioxide gives you a carbonic acid solution which when mixing with metal oxide-bearing rocks like basalt (rich in calcium and magnesium, etc.) forms stable carbonate minerals like calcite and magnesite.
This is high school chemistry stuff, right? Or was my poor Southern state public HS education actually exceptional?
The chemistry part is not surprising [1], but I have very litle idea of the composition of rocks, I expected them to be salts like silicates, carbonates, sulfates that don't react with carbonic acid. [2]
[1] I had a specialization in Chemistry in my high school, so I don't know it it's normal to know that.
[2] IIRC someone posted a project to make huge beaches of malaquite. (It would be weird/nice, becuse it's green.). The idea is that it reacts with the CO2, and the waves would do much of the work to break them in small pieces. If I guess correctly, the reaction is Cu2CO3(OH)2 + CO2 -> 2 CuCO3 + H2O
