  In this work, we analyzed an anomalous effect verified from symmetrical
capacitor devices, working in very high electric potentials. The mastery of
that effect could mean in the future the possible substitution of propulsion
technology based on fuels by single electrical propulsion systems. From
experimental measurements, we detected small variations of the device inertia
that cannot be associated with known interactions, so that the raised force
apparently has not been completely elucidated by current theories. We measured
such variations within an accurate range and we proposed that the experimental
results can be explained by relations like Clausius-Mossotti one, in order to
quantify the dipole forces that appear in the devices. The values of the weight
losses in the capacitors were calculated by means of the theoretical proposal
and indicated good agreement with our experimental measurements for 7kV and
with many other experimental works.
