There is one claim in the video that I think is probably partly true, about the cause of X-rays seen from comets having an electrical origin. So it's a shame they have to bury some interesting information like this in a sea of twisting the facts about no water ice on comets (it's in them, not on them), formation of things that look like impact craters from electric arcs rather than impacts, etc.

The biggest discrepancy is the electric comet video claims the comet has a negative electrical charge, and that has something to do with it, where as the Japan space agency description says this charge exchange might occur even with neutral materials in the comet.
A clue to pinpointing the origin of the mysterious X-ray enhancement was provided by quite an unexpected finding: the discovery of X-rays from comets. In 1996, comet Hyakutake approached only 0.1 AU (astronomic unit) away from the earth and observations were conducted in various wavelengths. Since X-rays are generally emitted from hot gases of 1 million Kelvin or more, it is unthinkable that comets, ice and dust-clustered objects, alone would emit X-rays. Contrary to our expectations, strong soft X-ray emission was observed from comet Hyakutake. Intrigued by this discovery, X-ray emission from comets has been confirmed in succession, which convinced us that soft X-ray emission is a common phenomenon with many comets. With this new finding, theoretical and experimental research on soft X-ray emission mechanism advanced. As a result, it was posited that “soft X-rays from comets are emitted by the charge exchange interaction between ions in the solar wind and neutral materials in the comet.”
Slightly off the topic of the electric comet video but not too far off and possibly somewhat related, EU proponents do cite work done by Nobel-prize winning scientist Hannes Alfven. Alfven did some good work on MHD but his denial of big bang theory in spite of all the evidence supporting it didn't get him a lot of mainstream support. His theory didn't really explain the evidence:

In 1993, theoretical cosmologist Jim Peebles criticized the cosmology of Klein (1971) and Alfvén's 1966 book, Worlds-Antiworlds, writing that "there is no way that the results can be consistent with the isotropy of the cosmic microwave background radiation and X-ray backgrounds".[21] In his book he also claimed that Alfvén's models do not predict Hubble's law, the abundance of light elements, or the existence of the cosmic microwave background.

Venus doesn't have a comet tail. Please actually read the article you linked. Venus' ionosphere (which is invisible) stretches out away from the Sun like a comet's tail.
I have been looking into the EU some, but the more time I spend doing that, the more ridiculous it seems. A large part of "evidence" towards it seems to come from comparative mythology and interpreting cave paintings and clay tablets. Another off-putting factor is the allegation that we've all been lied to, that there's a global conspiracy to keep the truth from us, etc. apparently for some kind of gain or power hold. Typical conspiracy opera.
Still, my curiosity is tickled, and I'd love to see something more solid come out of the EU bonanza than big articles, long videos, and convention meetings. Science is what it is - show that a theory works, that it is supported with evidence, and that it answers the questions, and you're on a roll.

I dont really have the knowledge to form an informed conclusion on the matter, so as far as I am concerned the stuff in the video may be true or a load of BS. But I think it is important to consider claims of electric universe separately.
Actually, the Moon is a strong source of X-rays, and those originate from the solar wind particles striking heavy elements in the lunar soil. Perhaps cometary X-rays could have the same origin, i.e. interaction of solar wind particles with heavy elements in the comet?

The standard theorists are a bunch of lying thieves, intent on misleading the public so they can keep collecting their paychecks and wasting our money on their ridiculously expensive experiments.
Not just the comets, and not just the moon, but possibly most if not all objects in the solar system bombarded by solar wind, according to the Japan space agency's write up about research from their X-ray probe Suzaku:

The difference between comets and the moon would be that comets have a coma and the solar wind can interact with that. It doesn't have to wait until it reaches the surface of the comet to start interacting as happens on the moon.
On Jupiter, an X-ray emission phenomenon called the X-ray aurora is observed. Observational results from Suzaku suggest that a similar event occurs on earth. Of course, this result is a world first. ...
Soft X-rays are emitted around comets because of the charge exchange interaction of solar wind. In addition, it is suggested that the whole solar system also emits soft X-rays by the same mechanism. The emission provides us with an important clue for observational research on outer layers of atmosphere around the earth and planets, low-density neutral matter around comets, the ion composition of solar wind, etc.
That's a good question and I think it identifies one of the problems with the electric comet theory.

If comets produce OH due to solar win then would not all rocky bodies in the solar system lacking atmospheres display this same effect?
