Project Vesta for olivine drawdown leaves stealth mode

Olivine is a mineral that can sequester carbon dioxide through weathering. It's also one of the most common minerals in the Earth's upper mantle. A lot of it is just sitting around as waste rock from other mining operations. Project Vesta is working to turn olivine from waste into value, reverse climate change, and deacidify the world's oceans. Project Vesta cofounder Eric Matzner comes on the show to tell us how that works and what they're up to.
