Rocks are very dense. We are extremely good at mining and moving rocks. We produce 30 billion tons of concrete per year.
Naively, you would expect that producing and distributing crushed rocks sufficient to capture carbon would be equivalent to at most 10x the concrete industry. In practice, it’s likely closer to 1x.
- GeoAtreides 3y ago> Rocks are very dense Slighty off-topic, but I'm curious: what do you think requires more energy to move, 35 billion tons of steel or 35 billion tons of feathers?[*] [*] https://www.youtube.com/watch?v=-fC2oke5MFg https://www.youtube.com/watch?v=-fC2oke5MFg
- lumost 3y agoheh - I'm going to go out on a limb and guess that it takes more vehicle volume to move 35 billion tons of feathers. As Vehicle volume is correlated to vehicle weight, moving feathers will be more expensive :P but in all seriousness, the correspondence to rocks is beneficial as it's not obvious just how much mass industry moves in 2023. If you add in waste rock at quarries the numbers rise precipitously. A single shovel bucket can move 20 tons.
