There is also no radiation or ground heating from DC.

Jon, that's not right (not completely). ANY conductor carrying a current
induces a magnetic flux around itself, the strength of which is entirely
dependent upon current, not voltage.

Although AC transmission produces a moving (alternating) magnetic field
that can induce currents in still objects (like the ground, yes), the
magnetic field around a DC conductor can still induce currents in moving
objects (like people, vehicles, etc.).

So it's not right to say a DC conductor doesn't "radiate", because it
does radiate a magnetic field. It just happens to be a static field, so
long as the current remains constant. Vary the current, and you have a
varying field with similar (if reduced) effects like those of an AC
transmission line.
