And that is what I stated in my ETA.No RC, the *SURROUNDING MEDIUM* is air, but the conductive path that enables the "discharge" (release of stored energy) occurs in the CONDUCTIVE PLASMA. The discharge process occurs IN THE PLASMA, not the "air.
Oh please. He called them "electrical discharges" which he associated with limited duration solar flare events. You're the one insisting his statements be "dumbed down" to "release of magnetic or electic energy".Oh please. He called them "electrical discharges" which he associated with limited duration solar flare events. You're the one insisting his statements be "dumbed down" to "big current".
You're the one unable to read his paper and see that the context of his use of "electrical discharges" is high current densities.
You are lying: Alfven and Dungey never define electrical discharges as "a discharge of stored EM energy".
In fact no one defines electric discharges despite your cherry picking of Peratt's first sentence.

Dungey's and Peratt's definition of discharge are different.
Wrong: He specifically used \both terms, definiing a discharge as a "current", i.e. lots of electrons travelling at high speed in the same direction.Yes he did. He specifically used the term "discharge", not just "current".

Wriog: An electrical discharge as used by Dungey is a high current density, AKA a high current density.In other words, high current densities were released from stored electromagnetic field energy, AKA a "discharge".
You are lying again MM:You've been claiming that conductors cannot experience "electrical discharges". He said exactly the opposite RC. He used the term "electrical discharge".
I have stated that the usual defintion of electrical discharge cannot happen in plasma, e.g. Peratt's defintion.
Dungey does not use that defintion of electrical discharge. See above.
I agree - I have no credentials specifically in solar physics. That does not matter (see below).Emphasis mine. In this specific field, none, but "credentials" seem to be irrelevant.
Neither do you. Neither for example does Anthony Peratt - his credentials are in electrical engineering.
You are lying again. I know a lot about the behaviors of *PLASMAS* for a couple of reasonsYou seem to know absolutely nothing about the behaviors of *PLASMAS* (rather than solids), and in fact your "credentials" seem to be in the way of you actually understanding any of the "behaviors' of "plasmas" as far as I can tell.
- Science degrees include learning about many areas of science. I not only learnt about sold state physics (my main area of research). I also learnt about plasmas (and gases and liquids).
- I have continued to learn about science. That includes plasmas.
