I actually like the Electric Universe ideas but they actually relate to dark matter/dark energy ideas too. When I said I like dark matter for the 3 or 4 to one ratio (via bullet cluster/WMAP observations) not for galactic rotations (10 to 100 to one ratio dark matter to ordinary matter required), I had Electric Universe ideas in mind for galaxy rotations (which in my mind relate to dark energy).

Here's the same guy (Tony Smith) I linked to before for dark energy and dark matter with another dark energy/dark matter link that has Birkeland current pictures from the thunderbolts.info site you mention:

Most of my knowledge of Wallace Thornhill and the Thunderbolts Project came via websites owned by physicist Arkadiusz Jadczyk and his wife Laura. They own a news site where they did a radio interview of Thornhill:

Thornhill from that interview: "the longitudinal electric force was of profound importance... But in the electric universe where you understand gravity as an electrical phenomenon "

It relates to this:

http://en.wikipedia.org/wiki/Talk:Longitudinal_wave

... longitudinal plasma waves and longitudinal electromagnetic waves are similar... the appearance of longitudinal waves in such a case does not in anyway contradict Maxwell's equation. In fact to obtain the waves, you use Maxwell's equations...

back to me: The full symmetry group for Maxwell's equations is the conformal group which also contains the rotations, boosts and translations for gravity. Then add in:

"In American Journal of Physics 39 (1971) 901-904,

David Finkelstein showed that in Unimodular Relativity

the Cosmological Constant is an unavoidable Lagrange

Multiplier beloging to a constraint that expresses

the existence of a Fundamental Volume Element of

Spacetime Hypervolume at every point of Spacetime.

Unimodular SL(4) is related to SU(2,2) which is

isomorphic to the Conformal Group Spin(2,4). "

and you have the same math handling longitudinal EM waves, gravity, and the cosmological constant (aka dark energy). Fitting in regular EM is actually a bit complicated however (it adds in along with the nuclear forces).
