The plus as well as the minus-potential (/pressure) are not the same along their lines and this may also affect the result.
If an an electrical discharge through the air is largely carried by positive ions then, I guess, a current of air (wind blowing) should be detected between the electrodes.

I found an experiment video on youtube, and I think it's relevant to put here.(+) vs (-) Underwater Lightning- is there a difference?//www.youtube.com/watch?v=a1NvSSuuVF4

This is one more evidence that the Plus-electricity has a property of blowing, whereas the Minus-electricity a property of suctioning.
This principle can be found in many things, among others also in the so-called “Bernoulli’s principle”.
(see What is the Bernoulli's principle? https://www.thenakedscientists.com/forum/index.php?)topic=17067.msg587651#msg587651)
In other words, the electricity is Plus, the magneticity is Minus.
This is a polarity of first order. There is further once more a Plus and a Minus both in electricity and in magneticity. It is a polarity of second order.
Why do you do this?
If you live long enough, you will understand.
Thanks for letting me know about the bad link.

The time will tell what a nonsense is, whether my explanation or some tiny particles running through the wires.The time will tell what a nonsense is, whether the real flow of the current is from Plus to Minus or vice versa.The time will what a nonsense is, whether the magnetic field (actually the magnetic current) is spirally shaped or like many rings closed in themselves.

I tried reversing the polarity but it doesn’t levitate. It sits a couple of mm above the bottom plate. Also the Corona hissing goes away with the polarity reversed. May need a different aluminum form.
What is a complementary device and why has it not been possible to create a complementary VFET?In conventional metal oxide semiconductor field effect transistors (MOSFETs), we have n-type and p-type devices –NMOS and PMOS respectively. This is readily possible since semiconductors can be doped either way. The availability of these two types allows construction of a CMOS with the two devices working as a pair. When connected to a common input voltage, they work in opposite fashion: when one transistor is on, the other is off. This allows the CMOS to operate using less power.Complementary operation of VFET has not been possible because there is no semiconductor material in the channel for doping and no possibility to create holes to make a p-type device. VFET is unipolar since it is electron only.How does your design overcome these challenges?The primary (or the only) source of carriers in a vacuum device is electrons, resulting from the field emission in the source electrode. In the absence of holes, we need an external mechanism to invoke complementary operation (see figure below). That mechanism here is the nanoelectromechanical (NEM) actuation of the gate that modulates the vacuum channel length and resultantly the electron transport across the source-drain channel with the gate voltage. A shorter vacuum channel length is formed, and a positive input voltage turns on the n-type device and a negative input voltage turns on the p-type device.The NEM-driven gate modulation is a successful technology employed in NEMS-relay switches and other low power electronics.
