    A recent startling discovery in electrostatics has been made, which
    200 year old physics predicts, but which for some reason has been
    overlooked until recently.

    Apparently if you charge up a sphere to a modest few kilovolts,
    fixed in place, and then suspend two other spheres close by, the
    other two spheres rotate. In the experiments described in the
    references below, they didn't
    actually rotate, but instead torqued up their suspension filaments
    until the restoring force equalled the torque.

    They characterise this effect as a "Coulomb motor". My question is
    this: If it's a motor, where does the energy come from?

    I assume that femm could model this in axisymmetric mode...but would
    it come up with the observed torques?
