 Author Nicola Twilley's new book, Frostbite, details modern refrigeration. This week, Motley Fool Money's Ricky Mulvey caught up with her about the history and what its evolution can teach us about the development of other technologies today. Nicola Twilley's book is Frostbite, How Refrigeration Changed Our Food, Our Planet, and Ourselves. She's also the host of Gastropod, a podcast I enjoy and a contributor to The New Yorker. Thanks for joining us on Motley Fool Money. Thanks for having me.
