My evidence is that the spacesuits shown have never in their over 50 years of alleged use been publicly demonstrated by NASA to work in a high vacuum chamber on Earth duplicating environmental conditions of orbit.
False according to evidence presented, and in any case a narrowly-tailored straw man. Your contrived personal definition of a "public demonstration" does not create a controversy that others are bound to respect.
Only until recently after my agitation could a photograph of a spacesuit ice sublimator be seen on the Internet.
Records were produced proving otherwise. You are not responsible for the publication on the internet of photographs of sublimators.
And despite representing one of the most interesting and exotic heat transfer devices ever contrived...
Phase-change cooling is far from "exotic." Have you ever heard of swamp cooler? And sublimation cooling is no more exotic than, say, a Joule-Thompson device, which is also commonly used on spacecraft.
...no spacesuit ice sublimator is mentioned in any academic-level heat transfer or thermodynamics book.
The most widely referenced free textbook (Lienhard) on heat transfer, from an MIT professor, has an entire chapter on phase-change methods of heat transfer.
Further this is another straw man. Heat transfer and thermodynamics textbooks rarely describe
any commercial products that effect the principles they describe. They are primarily physics textbooks. The standard
engineering reference on spacecraft design (Fortescue
et al.) has an entire chapter on thermal design, including a discussion of both practical phase-change mechanisms and limits on practical testing of thermal control methods on Earth. Looking in the wrong places and handwaving about allegedly suspicious omissions does not create an argument those skilled in the art are obliged to respect.
It's evidence of anomalous spacesuits.
No, the more parsimonious interpretation is that you overstate the degree of research you have done as well as misrepresent the findings, and present only a fairly easily refutable argument from silence. Your personal incredulity and your personal ineptitude at research is not probative of anything except those things.
