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 ). The basic principle of the Lafforgue's device is to use an asymmetrical electrostatic pressure for producing a thrust Vs external referential ( the Universe ), this is fully explained in his patent. Lafforgue has called this the " Action Force " or the " Expansion Force ".

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

This experiment shows the electrostatic pressure in action on a soap bubble.

Experiment description :

This experiment is very simple and can be replicated by anyone. You only need to have :

Experiment : The HV output of your power supply is connected as shown in the diagram above. Then, with the ring, blow a big bubble, drop it on top of the container and switch on the HV power supply...

TESTS RESULTS :

When High Voltage ( +25 KV DC ) is switched on the soap bubble inflates and leaves the device upwards only by the electrostatic pressure ( see the photos below ) :

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.

Systèmes isolés auto-propulsés par des forces électrostatiques

Les forces électrostatiques sont " engendrées " par interaction d'atomes polarisés (q) sur un champ vectoriel électrique (E), soit F = q. E positive ou négative selon le signe de (q). Par une géométrie adaptée des armatures polarisées, et / ou par l'utilisation de charges électriques induites par effet d'influence, et / ou par l'utilisation de diélectriques convenablement disposés, il devient possible de rompre la symétrie des forces d'expansion sur l'un des axes du trièdre de référence et obtenir ainsi une force résultante ( F n ) non nulle. Le système isolé est alors propulsé et il entraîne avec lui les charges (q) et (E), donc F = q. E reste constant. Cette force peut être utilisée comme moyen de propulsion de tout engin ou bien comme force motrice pour produire de l'énergie.

Un très court extrait de ce brevet ( 55 pages ) : " Cette disposition permet à tout engin ainsi équipé, et surtout aéronautique et spatial, de pouvoir changer de direction extrêmement rapidement, voire de s'immobiliser, puis de repartir en sens inverse promptement…"
