Who said this "It [the "Birkeland solar model"] wasn't limited to a "solid surface" concept, it was related to an "electric universe" concept"?
Now according to a large number of JREF members (mgmirkin, solrey, sol88, Anaconda, Zeuzzz, ...), Don Scott is the most reliable, most comprehensive, most up-to-date definitive source when it comes to "electric universe concepts" (though Wal Thornhill comes a close second).
This is a conclusion backed up by google searches - google "electric universe" (and exclude the music) and you'll find a great many websites confirming the above (and none, that I could find, to the contrary).
Now Don Scott has written a book on this topic, in which he makes perfectly clear that it is external current flows which power the Sun (and indeed all stars); he and Thornhill even had a paper published (by IEEE) on this.
But, as we have seen so many times already, perhaps what you, MM, mean by ""electric universe" concept" is something totally different?
