Lerner may have an undergrad degree in physics but he is not a plasma physicist. He doesn't have the necessary qualifications. He doesn't have any graduate degrees, let alone a PhD or post doctoral research experience under the supervision of a professor/lecturer at an university. All he has is the right to claim to be a CEO of his own company that deals in this area of physics...nothing more or less. Now, do I have to tell you for the umpteenth time again and again???
How thick can you be??
As for your last paragraph, don't try and hide behind it to make me out as being nonsensical. Crawling to Craig by appealing to him (or others by proxy) will not help you out one little bit. This has nothing to do with inquisitiveness or anything else. This has to do with your inability to to be able to show any verifiable evidence for anything you say....
What has the current density in a transmission line and modes of plasma got to do with plasma cosmology or anything in astrophysics??!!!. You have been told on any number of occasions by not only Steven and myself, but by others, that you cannot apply a lab experiment to a real life situation just by scaling things up (or down). At the very best, you only have an approximation of what is going on, and in most cases you cannot tell what is happening simply because you cannot scale many of the factors involved in order to get a reasonable analogue. But that doesn't seem to sink in.
You have no idea about plasmas...do you??? Dark mode...you guys also love to trot that out as some mysterious factor hiding these currents. Do you even know what dark mode actually is??? Where is either the synchrotron radiation or bremsstrahlung from your said dark mode current??? It must be there, Alex...it's the nature of the current running through a resistive medium (the plasma and interplanetary gas/dust) or electrons accelerated in a magnetic field. Dark current doesn't mean hidden, it's the current that runs through a device (or in this case a plasma sheet) when there is no external input via another source (in the case of a CCD, photons....the plasma sheet, solar wind and CME's). Oh that's right, something is masking it. If something masks a current, Alex, the current breaks down because the separation of charge is negated in the plasma by the other ions present there. Go and read up on your plasmas, Alex. As a matter of fact, describing the plasma sheet as having a dark current is a furphy as there is always an input occurring via the solar wind. So trying to apply some engineering term to an astrophysical process is erroneous to begin with as there is no analogue present.
Here is a definition of dark (mode) current....
You can't even apply it with respect to planetary aurorae for exactly the same reasons. It is not being hidden by anything as any flow of electrons will generate a detectable source of radiation thermal and/or non thermal (synchrotron, x-ray, radio etc). Anything which can mask a current's flow or emissions will collapse the generation of that current...and in the case of the aurorae, there's goes your Birkeland currents.
So, Alex, I suggest it's back to the drawing boards for you all.

You absolute fool.
You do nothing but clutch to copying and pasting
wikipedia articles in some vein attempt to come across as knowledgeable?
There are 3 modes of plasma emission, which track a non linear voltage gradients, all very well understood and scalable.
Dark = yep, generally dark (solar wind etc)... occasionally radio emissions exist.
Glow = yep.. it glows... go figure (flouro lamps, auroras).
Arc = yep... arcs... (lightning).
Sydney Chapman tried to tell
Kristian Birkeland he couldn't scale plasmas... guess who had the
last laugh, once
spaceprobes could take insitu measurements (nasa themis image)?
Plasmas can and do scale, this is a well established empirical fact.
All the best,
PS: only you have said that plasmas and experiments cannot scale, Steven has not.
PS: "It's not who or what funds his work, or what he may have published that makes him what he is, it's his qualifications"
sorry mate... Oliver Heaviside was brilliant... should we begin on countless others? I'd rather go off their achievements and contributions rather than pieces of paper with fancy embossing... maybe we've found our difference here carl?
