This is a test of a single Townsend Brown asymmetrical capacitor ( a single Lifter element ) in presence of smoke. The device has been placed on the same high sensitive beam balance used for the smoke tests of Lafforgue Field Propulsion Thruster ( see the Tests of the LFPT v1.2 with smoke ).

The purpose of this test is to check if the upwards thrust observed is produced by a simple electrokinetic effect ( EHD/EKP ) and/or by an electroaerodynamic effect ( AED ).

A smoke generator ( a simple incense burning stick ) has been placed just in front of the middle of the Lifter plate. The smoke path has been observed without and with the High Voltage. If the thrust is the result of the acceleration of the air produced by an electrokinetic or electroaerodynamic thrust, the smoke flow will be sucked downwards while the Lifter goes upwards ( principle of action/reaction ).

Lifter element specifications
  • Aluminum plate : 75 x 20 mm ( 0.5 mm thick)

  • Wire : copper 1/10 mm diameter

  • Gap betwee the wire and the plate : 35 mm

  • Working voltage : 18 KV DC

TESTS RESULTS ( 09-02-03 ) :

The smoke flows upwards in straight line without High Voltage and without motion of the Lifter ( see the photo below )

When the High Voltage generator is switched on, the Lifter goes upwards and
the smoke is quickly pulled downwards ( see the photo below )

When the High Voltage is completly stopped, the Lifter keeps on oscillating for a while.
The smoke returns slowly to its original path upwards
( see the photo below ).

Comments : The test of the Lifter in presence of smoke confirms that the major thrust upwards is produced by an elektrokinetic effect ( EKP ) as Townsend Brown has fully explained in his patent "Electrokinetic apparatus".

It is interesting to compare the Lifter with the Lafforgue Field Propulsion Thruster ( LFPT ) :
