This sighting, seen by another person besides myself, caused me to ask why the these circular illuminated spots. Thanks to the on~going attempt to replicate the Alexey device I now think I have a possible explanation.
Dielectric Barrier Discharge & Cold Atmospheric Plasma.
It has been known that Cold Atmospheric Plasma's can be made from Helium, Argon, Nitrogen, Heliox, and air. Siemens was the first to conduct experiments on Dielectric Barrier Discharge in 1857. More recently Darpa has verified the ability to sustain an open air plasmoid. There are two types of plasma's. Cold Atmospheric Plasma (CAP) is said to be non-thermal because it's electrons are at a hotter temperature than heavy particles which are at room temperature. Cold Atmospheric Plasma's are created through a dielectric barrier discharge (DBD), and which consists of two flat metal electrodes covered with a dielectric material. A carrier gas, such as air, moves between the two electrodes and is ionized by High Voltage to create plasma.
One electrode is a high voltage electrode and the other is a grounded electrode. Alternating Current (AC) of high voltage powers the dielectric barrier with high frequencies. Electrodes can be cylindrical or flat and the dielectric material may cover one electrode or both.
Atmospheric Pressure Plasma Jet (APPJ).
An Atmospheric Pressure Plasma Jet is a radio frequency plasma. The APPJ consists of two coaxial electrodes between which a feed gas ( can be mixtures of helium, oxygen, and other gases) flows at a high rate. The outer electrode is grounded while a Radio Frequency (RF) power is applied to the central electrode that creates a discharge.
