You don't. The helium layer is ABOVE the iron layer. It the iron layer was above the helium as NASA claims THEN your criticism has merit, hence my model over theirs. |
BZZT. wrong answer. The He line at 304 Angstrom represents a temperature of 60,000 K. Again I refer you to the SOHO scientists who presumably know what they're talking about.

No Mike, I know exactly what I'm talking about. I'm a physicist and have been studying problems such as this for over 20 years. I think I have a good feel for what's physically plausible and what isn't. Solid layers of iron at MegaKelvin temperatures and a sun powered by nuclear fission aren't among them. As to undermining your credibility, I have no need to do that.

Its that kind of arrogance that has led to this problem in the first place. If you have all this experience on these issues, please explain to me why electricity cannot possibly be the heat source rather than the corona.

To say nothing of the arrogance that treats all of the scientists of the last century or so (with the exception of Manuel, of course) as purveyors of a hidebound orthodoxy who don't recognize what's before their eyes. (I refer the reader to Mike's comments on the scientists at LockMart and at SOHO).
Electricity as such is not a heat source. It needs to pass through a material and dissapate energy through resistance. Electric currents in the corona are one possible mechanism for heating it. Others that could also contribute are convection transfer from the sun itself and radiant heat transfer as the corona absorbs photons emitted by the sun. As the temperature of the coronal material goes up, different levels of ionization occur. The different lines seen by SOHO come from these different ionizations. The 284 Angstrom line represents iron that has been ionized 14 times (that is fourteen of the 26 electrons removed) that takes a lot of energy, such as that available at a temperature of 2 MK.
