Michael returns to talk with legendary educator and inventor, Donald Sadoway, Professor Emeritus of Materials Chemistry at MIT. After earning his PhD in chemical metallurgy in 1977 at the University of Toronto, he joined the faculty at MIT where he spent 44 years. For 16 of those, he taught 3.091 (Introduction to Solid-State Chemistry)—and his animated lectures, peppered with references to music, art, and literature—doubtless contributed to the subject’s popularity. Among the many accolades bestowed on Professor Sadoway in his 44 years as a teacher and researcher at MIT was a compliment by Bill Gates: “best chemistry lessons anywhere. Unbelievable.” In 2012, for the invention of the liquid metal battery, he was named by Time magazine one of the “100 Most Influential People in the World.” He has founded several hard tech startups, including Ambri, Avanti Battery Company, Pure Lithium and Boston Metal.  Links Review Donald's 2012 TED talk, "The Missing Link to Renewable Energy" here: https://www.ted.com/talks/donald_sadoway_the_missing_link_to_renewable_energy?language=enExplore Avanti Battery Company's tech here: https://avanti.energyExplore Ambri's tech here: https://ambri.comExplore Pure Lithium's tech here: https://www.purelithium.ioExplore Boston Metal's tech here: https://www.bostonmetal.comExplore Sadoway Labs' research here: https://sadowaylabs.orgTake Prof Sadoway's course, 3.091 - Introduction to Solid State Chemistry - here: https://ocw.mit.edu/courses/3-091sc-introduction-to-solid-state-chemistry-fall-2010/   Related Episodes Metals Refining - From Mining to Brining - Ep142: Alex Grant: https://www.cleaningup.live/metals-refining-from-mining-to-brining-ep-142-alex-grant/Iron-Air Man - Ep144: Mateo Jaramillo: https://www.cleaningup.live/iron-air-man-ep144-mateo-jaramillo/
