On 29 February 2012, Sadoway gave a TED talk on his invention of the liquid metal battery for grid-scale storage. The talk is as much about the inventive process as it is about the technology.
Sadoway was named one of Time magazine's 100 Most Influential People in the World in 2012 for accomplishments in energy storage as well as his approach to mentoring students (hire the novice instead of the expert).
On 22 October 2012, Sadoway appeared as a guest on The Colbert Report to discuss his liquid metal battery technology and his view that electrochemistry is the key to world peace (batteries usher in the electric age reducing the dependence on petroleum dropping its price thereby destabilizing dictatorships).
Sadoway appeared in "MIT Gangnam Style".
