Donald Sadoway, MIT materials science professor and inventor of a new liquid metal battery that could revolutionize energy storage, went on Stephen Colbert’s show last night. The segment wasn’t all that funny, per se, but it was surprisingly informative — Sadoway didn’t get rattled by Colbert’s “relentless ignoramus” routine, and Colbert knew when to back off and just let the good doctor do his spiel. Definitely not the biggest laugh riot of all the Colbert clips we’ve posted, but you will come out of this one knowing more about liquid metal batteries and their potential.
