trouble is neither electrostatics or magnetics can provide stable levitation
from a static field. In both cases there will be an equipotential (surface
that the levitated device can move in without doing work against the field)
and since this equiptotential will surround the base station it will be
possible to fall down it.

so you need to dynamically adjust the field to correct for errors in the
objects position and try and keep the object sitting on top of the field.
This will take energy and the ammount will increase significantly if the
load contains any movement.
