AB  - We investigate the limits of high energy transport in multiwalled carbon 
      nanotubes (MWNTs). In contrast to metal wires, MWNTs do not fail in the 
      continuous, accelerating manner typical of electromigration. Instead, they fail 
      via a series of sharp, equally sized current steps. We assign these steps to the 
      sequential destruction of individual nanotube shells, consistent with the MWNT's 
      concentric-shell geometry. Furthermore, the initiation of this failure is very 
      sensitive to air exposure. In air failure is initiated by oxidation at a 
      particular power, whereas in vacuum MWNTs can withstand much higher power 
      densities and reach their full current carrying capacities.
