On January 23, 2002, I have tested successfully the Jean-Claude Lafforgue's basic experiment about the Electrostatic Pressure. An asymmetrical electrostatic pressure is the main principle used in his patent for producing a thrust Vs external referential ( the Universe ). Lafforgue has called this the " Action Force " or the " Expansion Force ". The setup of this electrostatic pressure experiment is fully described in his patent FR2651388 page 35. Some translations of the Lafforgue's patent can be found here.

This experiment is well known in high schools ( i.e : See " Electrostatique, Electrocinétique " by Maurice Ravaille - Collection de Sciences Physiques dirigée par Marcel Peschard Edition Baillère, page 125 ).

Tested apparatus description :

I have used a glass aerometer ( hydrometer ) commonly used for measuring the liquid density. The upper part of the glass aerometer has been covered with an aluminum sheet on about 50mm length, see the photo below :

Then the areometer ( hydrometer ) is placed in a plastic vessel filled with a mixture of 1.25 Liter of water and 1 coffee spoon of salt. The bottom end of the aluminum shape must be just about 15 mm below the surface of the salt water. A copper wire is immersed in the water and connected to a +30 KV DC power supply.

TESTS RESULTS ( 01-23-02 ) :

When High Voltage ( +30 KV DC ) is switched on the aerometer ( hydrometer ) goes upward because the resulting electrostatic pressure on all the conductive surface of the aerometer becomes asymmetrical ( see the photo below )

The electrostatic pressure is independant of the voltage polarity,
perpendicular to the conductive armature surface
and always towards the outside of the shape

P = dF / dS = s2/2eo

I encourage anyone who wants to conduct some researches in this domain, to study this patent very carefully....

Isolated systems self-propelled by electrostatic forces  by Jean-Claude Lafforgue ( France )

Abrégé
The electrostatic forces are "generated" by the interaction of polarised atoms (q) on an electric vector field (E), i.e. F=q.E, positive or negative according to the sign of (q). By suitable geometry of the polarised armatures, and/or by the use of electric charges induced by induction effect, and/or by the use of suitably arranged dielectrics, it becomes possible to break the symmetry of the expansion forces on one of the axes of the three-axis reference system and thus to obtain a non-zero resultant force (Fn). The isolated system is then propelled, and it draws the charges (q) and (E) along with it, thus F=q.E remains constant. This force can be used as a means of propulsion for any vehicle or even as motive force for producing energy.
