Elon Musk this year partnered with The X-Prize to create a $100 million prize for the best solutions for removing carbon dioxide from the atmosphere or ocean. This $100 million represents the biggest incentive prize in history, and likely the biggest single investment made into negative emissions to date. We talk wih the X-Prize's Executive Director Marcius Extavour and Erica Dodds, the CEO of the Foundation for Climate Restoration about the prize and the lay of the land when it comes to developing and executing these processes that would pull CO2 back out of the atmosphere.
