Jesus, your delusion knows no bounds, does it? Look up a definition of 'diamagnetic cavity'. There is nothing electrical going on on the surface of this comet. If there were there would be signs of it. It would be detected. Electric currents create magnetic fields. The comet, and the region within 4000 km of Halley, and within at least 186 km of 67P on 29 July, has no magnetic fields. That means, yet again, that there is no electrical activity within this cavity. There are no solar wind ions, with their easily detected magnetic field, within the cavity. It is an electric woo free zone.
And yet outgassing still occurs. How? Explain it genius.
If these currents you prattle on about were actually produced by the Sun, they would be detected. They are caused by interactions with other bodies which create those fields and various phenomena. If there was any current coming from the Sun it would be detected by various satellites and spacecraft that have been flying around for decades. They would be affected by such currents. They aren't seen because they aren't there. They would be obvious, and detectable everywhere. If you want to create a thread on the non-existent electric Sun garbage, I suggest you do that. The fact remains that for this comet you have absolutely zero evidence for any of this nonsense causing the outgassing. Zilch.
