What they say is what I say and what most people who have actually done some study on the matter say - it is appaling pseudo-scientific nonsense.
I spent some time looking into 'plasma physics' and 'electric universe' theories. They are so full of holes that no scientist I know even considers them to be real science - let alone credible physics.
What I think has happened is that all the electric and electronics lads have got a bit peed-off at all the attention the physics community is getting. They have therefore (through the IEEE) decided to establish their own cosmology and apply for nice grants :-)
Hannes Alfvn was a good plasma physicist but an awful cosmologist.
I recommend a search of the literature before taking this seriously. You will find a couple of dozen papers in the standard references - most from a journal setup by the IEEE specifically. Look further and you will find one name comes up time and again - A. L. Peratt.
Check the content of the papers and what you get is:
In my plasma lab I can make displays that look reely reely like that stuff in them galaxies and things. Therefore the universe must all behave like my lab machine...innit....
