Olivine; can we save the planet?

Kiwi scientists have devised a way to sequester massive amounts of carbon dioxide.

"New Zealand academics have figured out a way to sequester massive amounts of carbon dioxide using a common rock.

Sequestering is a method of capturing a material, in this case the climate change gas carbon dioxide, with another material from which it cannot escape.

So far, they’ve sequestered only a few grams of CO2 in a proof of concept exercise, but it looks theoretically possible to sequester an entire year of manmade CO2 emissions (about 40 billion tonnes in 2020) using a small percentage of the world’s supply of the rock, which is called “olivine”.  That’s a long way off because the scale needed to achieve anything is massive, say the academics leading this research, Allan Scott from the University of Canterbury and Christopher Oze from Occidental College, California."
