"That might sound like another kind of nuclear reactor, but under their theory, stars are not powered by nuclear fission or fusion at all, but are purely electrical/plasma phenomena."

No. The theory is that it is electrical phenomena that drive the fusion reactions instead of gravity pressure. Fusion still happens, as does transmutation synthesis of heavier elements.

“The theory is that it is electrical phenomena that drive the fusion reactions instead of gravity pressure”

Yes, I suppose I should have said “thermonuclear fusion” rather than just fusion, since there would still be fusing of elements happening, just not through the process that the standard model proposes.
