Today, no guest - just Matt, with the story of what one writer called “the best idea America ever had”: the national park. In 1872, in a country built on private property, the United States set aside Yellowstone as land that could never be owned by anyone - and then handed the idea to the world.

Today, Matt speaks with Ibhade Eigbobo, Director of Corporate Project Management at Budderfly, about why the small and midsize business sector is one of America's most underused energy assets.

Doug also explains how...

Today, Matt speaks with Peter Reinhardt, co-founder and CEO of Charm Industrial, about one of the most ambitious bets in climate tech: putting carbon back underground permanently.
