As
threatened promised, here is a take on part of Anariba's buffoonery.
This is from the intro pieces to the videos on dupetube, which I refuse to watch. It comes from
https://www.thunderbolts.info/wp/latest-tblog/ .
This is episode 3 – Solar Wind Sputtering and Its Relation to Water Observation in Comet 67P.
He basically quotes the findings from the paper, which is fine. Then his abysmal knowledge of comets comes to the fore. The following sentence sums it up: "Solar wind sputtering can explain dust jets and water ice formation in less illuminated areas of the comet, but not those areas facing the sun as the solar wind does not penetrate through the plasma sheath of the comet. These findings suggest another mechanism must be at work along with solar wind sputtering to generate all of the dust found in the coma. A corollary of this study is that proton ion implantation is more likely to occur in areas of less illumination."
Eh? Totally failing to grasp that sputtering has nothing whatsoever to do with the dust seen in the coma, which demonstrably comes from the outgassing vapour! If he'd have bothered to look at the figures in that paper (
http://www.aanda.org/articles/aa/pdf...aa25980-15.pdf) he'd have seen that the sputtered species counts were extremely low, and in no way could be seen in the coma. Therefore, there isn't a snowball's chance in hell that they could "explain dust jets and water ice formation in less illuminated areas of the comet." In the regions of highest sputtering ~600 counts, H2O >>>greater, hard to tell but probably 100s of thousands or more. So how many H2O molecules can be made from 600 SiO grains?
The rest of the stuff is about the lack of water ice on the surface, and has already been dealt with elsewhere. Seemingly he is unaware of MIROs latest findings of subsurfaace ice, as well as previous evidence at other comets. It is therefore irrelevant, and just further shows his apparent ignorance of the proton fluxes of the solar wind. And how it manages to burrow beneath the surface to create ice, whilst leaving the upper layers unaffected.
His conclusion is:
"Taken together, it is reasonable to attribute the observed water ice formed in less illuminated areas to proton (H+) implantation into refractory silicates where they interact with oxygen atoms located in the refractory silicate lattice structures. This is not unusual as it has already been demonstrated to occur in laboratory experiments and thought to be the dominant mechanism for water ice found on crater rims on the moon."
Where do they find these people?

. Even without the shielding of the coma, any proton ion implantation is less likely in those areas.
