To Lukraak_Sisser: most of the questions you've asked above would not be asked if you'd followed this discussion. Everyone's time is limited, and that includes my own. But your fourth question makes a key point pretty well.
Your acknowledgment above is probably more significant than you realize. HUNDREDS OF BILLIONS of dollars have been spent globally in recent decades trying to recreate, in a laboratory environment, the imagined thermonuclear furnace at the core of the Sun. The great attractor was the hope of ending the world's energy problems. But it does not appear that any experiment has succeeded in producing more energy than it required to get nuclear fusion. (Keep in mind that I'm making this statement based on information available three years ago; the paper I presented at the NPA mtg in 2011 has not been updated.)
What has not been explored with any seriousness is the possibility of significant electrical contributions to the Sun's activity from the heliosphere itself and beyond. To see why this is so important, one need only consider the results of the IBEX probe exploring the heliospheric boundary. Then ask what is acting to organize the astonishing ribbon of ENAs enclosing the boundary. The boundary environment cannot be electrically neutral.

As a footnote, I've been assured of a fascinating fact by one who would know. All of the theoretical predictions relating to neutral kinetics at the boundary—the very predictions from which the IBEX project emerged—were proven wrong. All, that is, except a prediction concerning electrical transactions across the boundary and into interstellar space.
Out of the Electric Universe movement, a laboratory project has emerged. It involves highly capable engineers and PhD's across a variety of specialties, including laboratory plasma science. It has led directly to the first experimental phases in a new conceptual approach to the Sun and to star formation. The project was initially funded with a million dollars (an interesting contrast to the BILLIONS already spent asking the wrong questions). The first test phase in the design of experiments has surprised every member of the team.
But yes, much more experimental work lies ahead of us. For example, the chamber used in the aforementioned experimental work will almost certainly provide an ideal environment for testing the electric comet. I'd love to say more, but I'd be betraying trust to do so.
