The problem isn't that you can't publish papers. It's that you can't even understand the papers you cite.

So your assertion based of a 1938 paper is not correct, unsurprisingly!
So, let's first have a look at the list of authors for that paper;

O. Pezzi, F. Pecora, J. le Roux, N. E. Engelbrecht, A. Greco, S. Servidio, H. V. Malova, O. V. Khabarova, O. Malandraki, R. Bruno, W. H. Matthaeus, G. Li, L. M. Zelenyi, R. A. Kislov, V. N. Obridko & V. D. Kuznetsov

We'll come back to a few of them.

Let's also look at some of the papers referenced in that paper;

F.V. Coroniti, On the tearing mode in quasi-neutral sheets. J. Geophys. Res. 85(A12), 6719–6728 (1980)

P.L. Pritchett, F.V. Coroniti, V.K. Decyk, Three-dimensional stability of thin quasi-neutral current sheets. J. Geophys. Res. 101(A12), 27413–27430 (1996)

M.I. Sitnov, H.V. Malova, A.T.Y. Lui, Quasi-neutral sheet tearing instability induced by electron preferential acceleration from stochasticity. J. Geophys. Res. 102(A1), 163–174 (1997) (I believe the latter author is known to Tusenfem. The second author is a co-author on the paper Sol88 linked!)

Back to the authors of this paper that Sol, for reasons known only to himself, thinks contradicts Alfven's claim that the solar wind has to be net neutral;

Let's just concentrate on the lead author and a couple of others, whose papers I have already dealt with on here;

O. Pezzi, H. V. Malova, & O. V. Khabarova.

(Bolded authors are co-authors of the Pezzi, et al paper linked by Sol.)

Differential kinetic dynamics and heating of ions in the turbulent solar wind
F Valentini, D Perrone, S Stabile, O Pezzi, S Servidio, R De Marco, F Marcucci, R Bruno, B Lavraud, J De Keyser, G Consolini, D Brienza, L Sorriso-Valvo, A Retinò, A Vaivads, M Salatti and P Veltri

Note that the average charge density over the simulation region is close to zero, which mean that the current sheet as a whole remains electrically neutral.
I could go on, but it is getting boring. Suffice to say that Sol's claim that the paper he linked contradicts Alfven's 'zero net current' claim form 1939, is due to his inability to understand what he is reading and quoting. Surprising absolutely nobody.

The problem was YOUR (mainstream Models)

Abstract

Our understanding of processes occurring in the heliosphere historically began
with reduced dimensionality - one-dimensional (1D) and two-dimensional (2D) sketches
and models, which aimed to illustrate views on large-scale structures in the solar wind. However,
any reduced dimensionality vision of the heliosphere limits the possible interpretations
of in-situ observations. Accounting for non-planar structures, e.g. current sheets, magnetic
islands, flux ropes as well as plasma bubbles, is decisive to shed the light on a variety of
phenomena, such as particle acceleration and energy dissipation.
Current Sheets, Plasmoids and Flux Ropes in the Heliosphere

When you do use the correct model,
Quote:
Modern theories and observational studies describe the HCS and similarly strong CSs as
essentially non-planar complex plasma structures surrounded by a plasma sheet in which numerous
small-scale reconnecting CSs separated by plasmoids occur (Khabarova et al. 2015;
Malova et al. 2018; Adhikari et al. 2019; Mingalev et al. 2019). CSs are unstable in natural
plasmas. Owing to the constantly changing environment, CSs are subject to different instabilities,
including the tearing instability (Zelenyi et al. 1998, 2004; Tenerani et al. 2015a).

These instabilities may impact CSs simultaneously with various fluctuations, destabilizing,
triggering nonlinear processes at CSs and even destroying them. Therefore, strong quasistable
CSs, such as the HCS and CSs at leading edges of ICMEs and CIRs/SIRs, represent a well-known source of turbulence and intermittency. On the other hand, numerous thin and
unstable CSs are generated in turbulent and intermittent regions (e.g., Servidio et al. (2009),
Matthaeus et al. (2015)). This dualism reflects an intrinsic tie between instabilities,

Quote:
Summarizing the results of studies of particle acceleration associated with magnetic
reconnection, we would like to stress out the fact that, besides the obvious role of the
reconnection-induced electric field, charged particles can be energized by the first- and
second-order Fermi mechanisms and the so-called anti-reconnection electric field operating
during contraction and merging of FRs/plasmoids/MIs (Zank et al. 2014; le Roux et al.
2015, 2016, 2019; Xia and Zharkova 2018, 2020).
The ELECTRIC UNIVERSE are not really concerned with magnetogravity of the mainstream in the least. Electric fields, Electric Currents...Electric Universe!

Modern views on this point

that the lack of 3D models due to an obvious complexity of their building as well as the insufficiency

The solar wind @jd116's scale is indeed homogeneous quasi-neutral plasma and no net current anywhere, doing anything.

The modern, mid 2000's on, is showing this interpretation to be totally incorrect. Pretty confident the Parker Solar Probe will upset the current paradigm.

These Electric currents (Birkeland currents for brevity)

CSs, FRs/MIs, and plasmoids/blobs of various origins and scales exist in the turbulent

in the heliosphere.

Including,
Quote:
"The fast solar wind helped to maintain the magnetic field signature over such a large distance. If it can persist as far as Ulysses, there's no reason to presume that it wouldn't continue to the edge of the heliosphere (the boundary about 100AU from the Sun between the solar wind and the interstellar medium)," says Jones, "This discovery makes us wonder whether Ulysses or other spacecraft have crossed a comet tail before. So we're going back to look again for other signatures. But it's probably a rare event," says Jones
PR 24-2000: Ulysses Feels the Brush of a Comet's Tail

There will also be a return current. As jd116 says.

It appears to me that Sol88’s EU is a version of the God of the Gaps argument: So far nothing indicates that EU is right, but there is still hope! The solar wind is more complicated than previously thought, so maybe EU can still topple all physics and be right after all! The Parker Solar Probe may still deliver results that could topple all of physics! Maybe another probe in a 100 years could prove EU right after all.

Hope is vanishing, but as long as magic is possible in some far future result, EU could still be right!

All electric phenomena are Birkeland currents! Plasma is not a gas!

Yes, it has to have ~ equal numbers of positive and negative charges in it. And nobody is claiming any differently.

Yes, we have already told you that there are currents within the solar wind. That does not make the solar wind a current. As Alfven explained in terms a 12 year old could understand. Learn to read.

The EU loons haven't got a clue about plasma physics. They have precisely no-one qualified in the subject, and nobody with a clue about the subject. Nor have they ever performed any sort of plasma modelling.

No it hasn't, and nobody with a clue is claiming otherwise. Which is why you can't show anyone claiming otherwise.

Quote:

There are no Birkeland currents in the heliosphere, other than those that exist in planetary magnetospheres.

Quote:
Which is not a Birkeland current! Learn to read. The only current you are getting in a cometary tail is a cross-tail current. Which is not a field-aligned current, and therefore cannot be a Birkeland current. As has already been explained to you.

Is a lie. And there is a very easy way to settle the question. Sol merely has to name the author/s he thinks have shown that the solar wind is not net neutral at macroscopic scales. Then I'll contact them. Loser never posts on here again. Deal?

I think we all know that Sol will avoid such a deal with yet another gish-gallop of wilful ignorance.

I’m working on a screenplay for a movie about the EU proponents titled The Fear of All Sums. It’s a comedy, of course.

Bumping the bolded part as it was predictably ignored.

Added to which it can be asked where are the gamma rays from the impossible fusion on the surface? Why aren't they there? Why are we here if such fusion was impossibly occurring?

Where are the incoming electrons that Scott requires? How are they getting past a magnetic field heading in the opposite direction?

All these questions cannot be answered by the adherents of the impossible electric sun woo.

And he screwed up the equations in that 'paper', as was discussed here and elsewhere. That is why it only exists in a predatory, non-peer-reviewed, pseudoscience rag.

Vague similarities?

That’s why I read the whole couple pages dedicated to plasma is a gas… it’s not it plasma, of which there is a zoo of types.

Do you accept that mainstream, with the clarity of the correct mode/model of plasma instability being applied, will come to the realisation that the solar wind is far more complex than just being a quasi neutral zephyr?

Data, from a number of mission to various planets n moons, asteroids, comets(great solar plasma probes) and thru the suns plasma boundaries, looks pretty solid when it includes current driven plasma instabilities.

Or

Is all a bit confronting?

Real scientists already know what the solar wind is, and what it contains. It is quasi-neutral at macroscopic scales. And has to be. As Alfven explained.
There is nothing proposed by EU non-scientists that anybody needs to take any notice of, as none of them have a clue about plasma physics, or even know what the solar wind is.

No.

Scott hit the nail on the head… the hang up was here, as I recall;

Quote:
One of the most extensive reviews of force-free currents in a cylindrical geometry by Botha & Evangelidis [25] con- tains several references to similar studies.

However, none of these investigators make the simplest assumptions: adopt a piece-wise linear approach, assume α to be any scalar value, and assume no variation of j or B in either the azimuthal or axial directions.

Such simplifications may not be justified on the solar surface, but are in deep space. Therefore, we derive here a simple solution that follows from this and carefully note the effect of the parameter α on the resulting model.
Scott Currents? Less turbulent plasmas.

Highly turbulent plasmas like the solar wind close to the stars, HH objects, AGN’s, quasars…, flux ropes seems the most common term used. Happy to call them Parker Currents. Seems these currents have not had time to get field aligned.

Birkeland current in planetary plasmaspheres.

ALL need an electric field.

Observations have shown that these loops have axially uniform cross‐sections (Bellan 2003). Their very small inverse aspect ratios are often used to justify the neglect of curvature and to model them as straight cylinders, which is known as the thin flux tube approximation (see Zhugzhda 1996; Van der Linden & Hood 1999; Lothian & Browning 2000, and references therein). Coronal loops are line‐tied to the photosphere (Berger 1991). As such, boundary conditions at the ends of the cylindrical axis are important, as the coronal physics are influenced by conditions at the photosphere and chromosphere (Aschwanden, Nightingale & Alexander 2000). As the solar wind moves away from the Sun, it carries the coronal flux tubes along with it.

More specifically, coronal mass ejections (Low 2001) form solar flux ropes (also known as interplanetary magnetic clouds) as they move in the solar wind away from the Sun.

Usually the plasma β≪ 1 for these flux ropes (Burlaga 1988), and Shimazu & Vandas (2002) have shown that as the flux ropes expand due to the ambient pressure decrease with distance from the Sun, they maintain a force‐free state. As such, the flux ropes are modelled locally as infinitely long cylinders described by linear force‐free magnetic fields (Burlaga 1988; Lepping et al. 2001; Berdichevsky, Lepping & Farrugia 2003).

Jd116, you may benefit from jotting this down somewhere….

They, being the multitude of electric currents and current driven instabilities.

Plasma is not a gas and the solar wind is not quasi neutral.

Scott's 'paper' was crap. As has been pointed out here and elsewhere. He screws up the equations at the start, and it just gets worse from thereon. If that were possible. He is not a plasma physicist, and is utterly clueless about the subject. Not to mention a whole bunch of other physics. Because he's an engineer. Not a physicist. He is suffering from a terminal case of Dunning-Kruger syndrome. Which seems to be contagious in EU circles. You and Thornhill have certainly caught it.

Yes it is, and nobody sane is claiming differently. And you cannot point to anyone sane making such a claim.

Are you saying, you, are a plasma physicist? Or that G. J. J. Botha, E. A. Evangelidis don’t know what they are talking about?

You seem to be hung up on a 1939 paper by a pioneer in plasma physics.

They are not saying that the solar wind is a net current. Learn to read. Nobody sane is claiming that. If you are claiming that these two authors are making such a claim, then accept the challenge I offered - I'll email them and see what they say about the net neutrality of the solar wind. Loser never posts here again. Deal?

No, that's just quasi-neutrality.

Heck, why do you think the charges might tend to get separated in the first place? Gravity is one reason.

Sure if it make you feel any better.

Not really even sure if that will clear up the point that the solar wind may be considered quasi neutral at the scale of the solar system.

I'd be more interested on their take of the pervasive electric currents that thread the solar wind.

Are you able to ask them that as well?

Quote:
Notable events

From May 10 to May 12, 1999, NASA's Advanced Composition Explorer (ACE) and WIND spacecraft observed a 98% decrease of solar wind density. This allowed energetic electrons from the Sun to flow to Earth in narrow beams known as "strahl", which caused a highly unusual "polar rain" event, in which a visible aurora appeared over the North Pole. In addition, Earth's magnetosphere increased to between 5 and 6 times its normal size.[64]

Or you saying the solar wind can not contain any current because of its (the solar wind) quasi neutrality?

For frak's sake! quasi-neutrality and currents are not related, apart from that they work with the same paricles.

quasi-neutral:

[img]http://latex.codecogs.com/gif.latex?
\Sigma_k n_k q_k = 0
[/img]

with k meaning all species of ions and electrons, n is density and q is charge, and the sum over an appropriately large volume, i.e. several times the largest Larmor radius.

A current:

[img]http://latex.codecogs.com/gif.latex?
{\bf J} = \Sigma_k n_k q_k {\bf v}_k
[/img]

where v is the velocity, and there is no volume involved.

I am sure jonesdave116 is fully aware of these definitions and also that the two are independent (for example one is a scalar and one is a vector). So, NO JD did not say what you think he is saying.

(not sure why (La)TeX is not working for me)

Great.

Don’t won’t to talk anymore about quasi neutrality in the bulk solar wind as jd116 natters about.

The BIRKELAND CURRENTS (field aligned, force free, electron flux ropes) and the shinanigans the zoo of current driven plasma instabilities causes in astrophysical plasmas.

Throw some nanodust into the mix…

And Sol chickens out. As predicted! Go back a number of pages and you will see where I said the solar wind can contain currents. I also said that the solar wind is quasi-neutral at macroscopic scales. And it is.
You will also see where I dealt with the strahl. Which part of this are you incapable of understanding?;

As previously noted, you haven't got a clue what you are talking about. And neither does Scott. Get over it.

What Birkeland currents? Who is claiming to see them outside of planetary magnetospheres within the solar wind? Nobody sane.

“Birkeland currents” is just Sol88’s shorthand for “something electrical”. He said so himself. It was easier than to find out which actual phenomenon he is dealing with. And it sort of sounds as if it supports EU.

No, we don't agree. Your clueless ex-EE requires the solar wind to be a net current. It isn't. Ergo, your cult is wrong, isn't it?
