Today's guest is Bara Cola, an Associate Professor of Mechanical Engineering at Georgia Tech. Once a walk-on college football player, Bara currently runs the NEST lab and is a world expert on the use of carbon nanotubes (and related materials) in thermal technologies. He joined me to talk about the history of carbon nanotubes, their uses, and the special place they hold in our hearts. (Recorded on January 15, 2016)
