In this experiment I have used two Basic Lifters mounted on the rotating apparatus, the purpose is to get more datas about the speed, the acceleration and the power ratio.

RotoLifter v1.0 : The design specifications are :

Experiment : I have used the same rotating apparatus and the same High Voltage generator than with the ACT v1.0 for conducting this test.

The two Lifters are fixed on a 440 mm diameter frictionless rotor, and the HV is sent through the main rotation axis.

TESTS RESULTS ( 11-28-01 ) : Successful

When the HV power supply ( 20 KV DC @ 120 uA ) is switched on, the RotoLifter v1.0 starts to rotate and accelerates very fast up to 118 RPM. You will find below the curves of the Linear speed ( m/s ) and the RPM Vs the time.

The detailled analysis of the experimental datas, with the wire (+) is shown below :

  ACT v1.0 ACT v3.0 v3.0 Vs v1.0 RotoLifter v1.0 RotoLifter Vs Act v1.0

Thruster Weight ( Kg )



3.4 more


2.2 less

Initial Acceleration ( m.s-2 )



2.0 less


6 more

Thrust ( mN )



1.7 more


2.7 more

HV Power Output ( W )



1.2 more


1.38 more

Thrust (mN) / Power (W)



1.4 more


2 more

Conclusion : You may notice in the datas above, that the Thrust/Power ratio and the acceleration are the best datas compared to the ACT design.

This experiment confirms that the asymmetry between the armatures of the capacitor contributes to give more thrust and also a better efficiency.
