This test is the continuation of the test done on March 6, 2003 about an unlinked Lifter with its wire in a vacuum tube. I have used the same vacuum tube apparatus with the tungsten wire. The purpose of this test is to check if the thrust observed previously was simply an electrostatic attraction of the aluminum armature towards the tube or a real electrodynamic thrust versus the external referential ( the lab ). So, the aluminum armature has been linked mechanically to the wire apparatus so as to build a true Lifter setup. This Lifter has been mounted on a rotating torsion system as shown in the photo below.

The aluminum plate of the Lifter is grounded.

Lifter specifications
  • Aluminum plate : 200 x 20 mm ( 12µm thick)

  • Wire : tungsten

  • Vacuum tubes : 38 mm diameter, 310 mm length, 60W/220

  • Working voltage : 25 KV DC

  • Total weight of the apparatus : 910 g


When the power supply is switched on, the Lifter begins to move in the direction of the wire as a common Lifter. There is neither corona effect nor ion wind effect in the vacuum tube, there is no hissing sound and the lifter moves very silently.

Above, an animated video of the experiment.

Comments : This test of a TRUE Lifter ( with the wire mechanically linked to the aluminum plate ) which moves with its wire placed in a vacuum tube confirms that the trust observed is really relative to an external referential and not a simple electrostatic attraction of the aluminum plate towards the wire.

Since the wire is placed in vacuum, there is no ionisation and Corona effect. The aluminum armature is attracted electrostatically by the dielectric medium ( the air ) outside the vacuum tube polarised by the strong electric field. In the case of the Lifter, the surrounding medium is therefore required for the motion. This is why, the Lifter is a fully asymmetric apparatus. The dielectric medium must not be linked to the frame of the Lifter ( a true Lifter fully enclosed in a box will not move ), it must be linked to an external referential ( the laboratory ). A polarisable dielectric medium is required to get a thrust.
