Seaweed is not only a trendy health food for humans and abundant nourishment for marine life, it’s also a potential tool for reversing climate change. Backed by an XPRIZE Carbon Removal grant, Pull to Refresh is a startup aiming to balance global atmospheric CO2 levels by sinking carbon-rich invasive seaweed to the floor of the deep Atlantic Ocean.
In this episode, Jon interviews company co-founders Laurel Tincher and Arin Crumley about their ambitious plans and the science behind using algae to neutralize carbon emissions. He also explores how Laurel and Arin built a prototype unmanned vessel for seaweed collection despite each having no engineering background.
