"......This serie of tests about the Cornille's electrostatic pendulum
has fully demonstrated that the real source of the thrust induced
on the device and responsible of its oscillations is only produced
by a simple EHD Effect. This EHD Effect is generated by the corona
discharge effect in the air between the two thin copper wires which
carry the High Voltage. These EHD forces are mechanically transmitted
to the masses and produce a common parametric excitation of this
pendulum. The shape and the structure of the masses have no importance
in this case ( conductive or not conductive, single or two masses,
spaced or not spaced )....."
