Hmmmmm ..... If I used half the weight of batteries for large coils and
then flew and navigated along the length of power lines, could I induce
enough current to keep me aloft?

Magnetic flux density diminishes with the square of the distance from
its source. You'd probably have to fly pretty close to the
transmission wire to obtain any meaningful inductive coupling.
