Note that the electric Sun hypothesis assumes that nuclear fission is taking place on its surface, and possibly in its corona, chromosphere and photosphere as well.
Nuclear fission is an exothermic reaction for all elements heavier than iron, and quite possibly for lighter elements as well.
This means that energy is added to the external environment through fission of heavy elements. The Sun is an electrical accelerator. It has a greater output of electric energy than its input.
This in turn explains where the cosmic currents come from. The source of the currents that power our Sun is other stars.
I like your suggestions about our electric Sun. I would caution about the last sentence on this page: “..explaining where the cosmic currents originate in the first place. The source of the currents that power our Sun is other stars.”
The key point of the Electric Universe theory is that electricity flows through the plasma filaments or Birkeland currents that form the Cosmic Web. These twisted tubes not only conduct but generate electricity by inductive means. After all they are detected by their circulating magnetic fields!
Both stars and galaxies are nothing more than z-pinch points (initially) in these conductive filaments. Galaxies form the power distribution platforms with stars converting the high energy electron flow into life-sustaining em radiation.
The point of my final sentence is that the cosmic Birkeland currents must have a source. Something must be driving them, and I’m suggesting that the driving force are the stars themselves. Birkeland currents create galaxies and stars, and stars create Birkeland currents. All of this is in turn driven by a process in which matter becomes heavier, as suggested by Halton Arp. My suggestion is that matter has a life cycle. Other suggestions as to the ultimate source of the energy driving the universe are of course most welcome, especially if they fit the Electric Universe paradigm.
