"I'm pretty sure this is just ionising air (stripping off some of the electrons from the N2, for example), and driving them through the electrical field between the strips of Aluminum foil; your TV does a similar thing when it take a cathode-ray (a beam of electrons) and uses electrical and magnetic fields to bend the beam in such a way to draw pictures on your screen...
The easy way to prove that it is just atmospheric ionisation, and not "anti-gravity", is to put one of these things in a vacuum chamber; if there is "anti-gravity", it should produce lift, otherwise it will just sit there..."You haven't done your homework on the subject.
But I have.
Biefeld-Brown Effect
Dr. Paul Biefeld used to do Einstein's homework while they were studying at the Polytechnic University in Zurich in 1900.
Dr. Paul Biefeld was a classmate of A. Einstein.
“Yes,” Biefeld told the Denison campus newspaper, “when Einstein would forget to go to a class, he would come and borrow my notes to get caught up on what he had missed."
Experimental proof that the vacuum consists of ether.
(vacuum test performed by Gravitec, increasing the voltage from 15kv to 18 kv, clear movement/thrust of the capacitor can be seen; near the end the power is switched off, and then turned on again, and we can the visible thrust of the capacitor for a second time)
The first video supplied by Gravitec in 2003:

One of the best videos which exemplifies the Biefeld-Brown effect in vacuum:

At the pressure of 1.72 x 10^-6 Torr ( High Vacuum conditions ), the apparatus rotates when the High Voltage is increased from 0 to +45 KV.

http://jnaudin.free.fr/lifters/musha/Musha.pdfExplanation of dynamical Biefeld-Brown Effect from the standpoint of ZPF field
In 1956, T.T. Brown presented a discovery known as the Biefeld-Bown effect (abbreviated B-B effect) that a sufficiently charged capacitor with dielectrics exhibited unidirectional thrust in the direction of the positive plate.
From the 1st of February until the 1st of March in 1996, the research group of the HONDA R&D Institute conducted experiments to verify the B-B effect with an improved experimental device which rejected the influence of corona discharges and electric wind around the capacitor by setting the capacitor in the insulator oil contained within a metallic vessel . . . The experimental results measured by the Honda research group are shown . . .
. . . The theoretical analysis result suggests that the impulsive electric field applied to the dielectric material may produce a sufficient artificial gravity to attain velocities comparable to chemical rockets.

Direct experimental proof that the ether propagates through vacuum, causing the antigravitational Biefeld-Brown effect.
No gas left in the experiments: they were performed in vacuum.
Calculations indicate that ionic wind is at least three orders of magnitude too small to explain the magnitude of the observed force on the capacitor (in open air experiments).
Also the experiments carried out at the Honda R&D eliminated the possibility of ionic winds.
