from wikipedia: "All the CO2 that is produced by burning one liter of oil can be sequestered by less than one liter of olivine."
Doesn't that require a monstrous amount of olivine to obtain significant effects?

A liter of oil produces 3 kilos of CO2, density of rocks is 3-4 kilos per liter.
Rather nice image for the idea of "not sustainable".
