> Globe-scale carbon sequestration would increase demand for olivine massively.

I ask too much, I know, but first-semester freshman macroeconomic comments drive me nuts. As demand increases, and as production rises to meet it, the entire economics of the production chain changes. Purchases amortize more quickly. Processes improve. Infrastructure gets more fully utilized. The effects of mass production are felt all the way down the supply chain. I mean, as far as I know. I'm no economist.

But anyone who implies that increased demand automatically means increased prices probably knows even less than me.
