A reference about this extraordinary affirmation would be interesting. The mechanism of ionic wind is well understood, and the effect can be even simulated with results that agree with experiments. There is nothing of "asymmetrical capacitor" in these devices. They don't store significant charge, and are practically pure nonlinear resistive elements.Hi PBT, There is a lot of misinformation and "theories" on force produced by asymmetric capacitors. For instance one misconception is air thrust causes lifting force. Actually, any air thrust is 2-3 orders of magnitude less than lifting force.
AC may work too, specially low-frequency AC, because the travel time of the ions across the device is small. It just happens that symmetrical AC sources of sufficient voltage are not so easy to build and there are less experiments done with them. Anyway, the current through the lifter would be somewhat asymmetrical due to the structure. I have tried a 5 kV NST, but the thrust produced was very small. Even a 100 uA electrostatic machine worked better. Enough voltage is important.Some folks deny lifters can be powered with HVAC. Just shows how much confusion and false theory surrounds lifters. All I can say is do the experiments.
