There are two things I've noticed about your side over the years, you hate electrical astronomy theories with a passion and you will go to any lengths to oversimplify everything to "magnetism". The problem DRD is you have the magnetic cart before the electric horse. The "current flow' is the power source, not the magnetic field. The magnetic field is a direct result of the current flowing through the thread. The coronal loop is not there hanging out all by it's lonesome as some kind of dense, non moving plasma and a sterile magnetic line. You have *EVERYTHING* backwards and "dumbed down" to "magnetism".
Let's look at one of these "current first, magnetic field second" "Birkeland solar models" shall we?

No PS, this is a matter of historical accuracy and historical reality. Birkeland certainly had a "solar model". I posted the NY times article for you didn't I? It wasn't limited to a "solid surface" concept, it was related to an "electric universe" concept. I'm personally willing to go with "solid" or "rigid". I'm completely and utterly "flexible". Both of those solar models however are "subsets" of a "Birkeland solar model". We could apply a Birkland solar model to a Anaxagoras type sphere. We could also apply it to a plasma layered and "rigid" type surface too. There are a million different possible ways we might try to express a "cathode solar model" but if there is current flow from the sun to the heliosphere, then they are all "Birkeland solar models"!
Start with "
from the sun": let's assume it's the cathode, i.e. the place to which electrons flow; let's also assume that the actual cathode is the photosphere, which is 700,000 km from the centre of the Sun (we can adjust the numbers a bit later).
Next, "
to the heliosphere": let's assume this is the surface of a sphere, whose radius is 100 au, with the Sun at its centre.
Now in all "
"electric universe" concepts" that I have seen, out there on the world-wide internet, the Sun is powered by a "
current flow", so in this first "
Birkeland solar model", the current must produce ~3.8 x 10^26 W, which is the observed power (energy per second) of the Sun.
How does the "
current flow" produce this power? Let's assume it does so by converting the kinetic energy of the electrons into electromagnetic radiation, on (or at) the photosphere. We won't worry ourselves about how this happens ("
electrical processes" perhaps), for now.
Let's keep it simple and assume that electrons arrive at the photosphere at the same rate as they leave the heliosphere - x electrons leave the heliosphere in one second, and x electrons arrive at the photosphere in one second. In other words, electrons are neither created nor destroyed between the heliosphere and photosphere, and that the current flow is a steady one.
So, how many electrons leave the heliosphere every second? Well, the electron density there is 10 million per cubic metre, and the electrons are moving at 6 million metres per second (again, we can adjust the numbers later), so across each square metre of heliosphere surface there will be 60 trillion electrons crossing every second. Now the heliosphere's surface is ~3 x 10^27 square metres, so 1.8 x 10^41 electrons depart for the photosphere every second.
How fast are these electrons moving when they reach the photosphere? Well, let's keep it very simple and use the physics of Birkeland's day; specifically the part of Newtonian physics which says that the kinetic energy of a body moving at speed v is half its mass times v squared. Now the mass of an electron is 9.1 x 10^-31 kg, and every second 1.8 x 10^41 electrons give up their kinetic energy for light. So we have a simple equation (Ne is the number of electrons, m the mass of an electron, and v its speed):
1/2 mv^2 * Ne = 3.8 x 10^26
which, when we plug in the numbers, gives us the speed of the electrons as 700 million metres per second.
Before I proceed to check this model against empirical reality (i.e. results of experiments in the lab),
I'd like MM - and brantc - to check this "Birkeland solar model" for any flaws, errors, shortcomings, etc.
Of course, every other JREF member reading this is more than welcome to do so too, but if you could, please limit your comments to any mistakes I may have made in my math.
I should add that I have developed this model using only the simplest formulae/math I could; in fact there's little here beyond arithmetic; some extremely simple algebra; the standard definitions of things like energy, power, and density; and the formula for kinetic energy.
