Inductive heating is caused by magnetic coupling between the source current and the load or heated item. Resistive heating is due to the current actually flowing from the source through the load and does not require magnetic coupling. The thought process mentioned in my last sentence involves direct resistive heating and does not depend upon a changing current. In that case a DC current could generate the heating. True inductive heating requires AC current flow.
Think of inductive heating as heating that occurs due to induced currents flowing through a resistive loop. The integrated time changing magnetic field that links through the loop causes a voltage to be induced. Current flows as a result of the induced voltage which generates heat as it flows through the resistive loop material.

Maybe the current in this case is more like a series of quantum pulses which might have the time varying property required. A great deal of the effect would depend upon the relative magnitude of the current and thus the flow characteristics of electrons within. I assumed that the basic experiment consists of a DC current instead of AC. AC current could certainly be used to generate inductive heating. The thought occurred to me that the uncertainty principle might allow a portion of the electron current to flow within the nearby conductors effectively bypassing the nanotube. If this theory is correct then the effective size of the electrons must be such that they extend outside of the tube.

I don't see why this would be something new.
