I'm just noting the relationship between the ideas described there and those used in eva, especially in the context of PWM, the AT field, and its relationship to the freudian libido. Also, these ideas have been widely controversial due to the creator's association with freud, and since Anno was researching freudian ideas, he is likely to come across stuff like that by its association.
Edit: Odic force had been mentioned in association, but I have never heard of that. I have heard some of the terms associated with this, however, despite not knowing the actual unified thing (cloudbusters and such are quite common elements in other pseudoscientific practices, and despite the fact that these ideas are considered ungrounded and such, they make their way into all sorts of fringe paranormal documents).
Plus, someone studying freud with an emphasis on the nuttier stuff will probably eventually come to this, and since it's more contemporary WITH freud (and despite, or because, of the fact that it's still practiced and given a weak OK by the psychiatric standards people) it would be more available, especially since Anno was looking for that kind of stuff. More likely than not, he wouldn't remember where it was he got the ideas (think chamber of Guf). Even if these ideas were not the original source, he may have gotten it from related ideas (such as Odic force, which I still don't have any idea about).
I would note, however, that Orgone is described as being:
1) A product of the libido
2) 'Body armor'
3) A subatomic phenomenon that is omnipresent
4) Potentially focused and "shot" (as cloudbusters would)
5) Harnessed and stored both by the body and through devices (associated with free energy, presumably meaning it could be converted into electricity despite it being described as heat)
Given the freudian basis of the theory here, I would consider it a good match, but I suggest you guys read about it and voice your concerns about whether or not it FITS, rather than whether or not Anno would know about it (we don't know Anno, but we know Eva -- Ockham's razor applies, since we can never presume to know the mind of Anno-sama our Elohim
).
