Can Turning CO2 to Stone Help Save the Planet?
Out of Our Elements hosts Caitlin Saks and Arlo Pérez Esquivel, joined by NOVA Producer Alex Clark, investigate how the planet naturally turns CO2 into stone over long periods of time, and how scientists and engineers are trying to speed up this process in hopes of capturing and storing atmospheric CO2.
They’re joined by Cornell University Environmental Engineer Greeshma Gadikota, who illustrates how you can test out a small-scale form of carbon sequestration in your own home, and Lamont Doherty Earth Observatory’s Angela Slagle, who explains which places on Earth and the kinds of oceanic rocks that could play a role in scaling up CO2-to-stone transformation.
