Electrically-powered Sun claims have far more severe problems than the standard solar model. The standard model difficulty in a thin layer above the photosphere. Electric Sun problems extend from the photosphere to the heliopause (~100 AU) and impacts everything from conservation of particle number and energy to radiation exposure of astronauts. Much of it can be demonstrated at the level of high-school AP physics.
