Much of this reminds me of the skill of "scrying". To scry or descry is to divine images usually from a still pool of water, slightly inked to make it darker. A polished thumbnail, also painted dark. And of course the old Hollywood standby of crystal ball gazing.
What perplexes the bejeepers out of me on the whole thing (having not been present to observe and/or record) is the clarity of the images produced. Especially given the budgetary and technological constraints of the time. You have to admit, those images are stonking good. Too good.
Personally, scrying is something I have no gift for. The time or five I was exposed to the process by a self-described psychic or sensitive - no results could be obtained if I was in the room. Yeah, I am that guy - that kills Ouija boards and crystal balls dead if I so much as think in their direction. *chuckle*
Now in a vacuum, the rarefied atmosphere will allow for more vigorous molecular/Brownian motion as there are far fewer particles to interact and collide with one another.
This is why a gizmo like the "Radiometer" works. The black and white painted sides create a "differential pressure" when the particles do collide. It's about 95% vacuum inside there. Heat stirs up the few remaining air molecules and strike the cards and vanes. If it strikes the black side, the energy of the impact is absorbed. If it strikes the white side, well, that energy is rebounded. This reflection of energy makes the vanes spin.
So I pose this question:
Without there being *something else* added to the vacuum that IS visible or at least interacts with infra-red/near infra-red light, how are these images produced and recorded? There is a missing "X" in the middle of all this and the report as rendered on the Vemboss web site.
Now I have more trust in the idea of vacuum tubes possibly working. As they are not physically capable of being in a complete vacuum when made. Note the dark, reflective ring where the flash pot went off and tarnished the glass envelope. That's fired when they seal the tube after drawing down the best possible vacuum on it. The flash pot burns all remaining oxygen in the tube, leaving other inert gasses behind. Hot cathode elements do not take well to oxygen in small amounts at the temperatures they operate at. :D
But here lies the "what if" in my post here - there is residue and free floating materials left within the void inside the vacuum tube that *may* be possible to image after the cathode heater's been active for a while and then shut off. It will DEFINITELY show up for a while until the infra-red spectrum quiets and the tube cools completely to ambient temperatures. If spirit can seem fit to be bothered to push a few threads of semi-warm residue suspended as vapor in a glass bulb, we'll have it cracked. :D One can get Sovtek power rectifier tubes, plenty of big, bulging bulbous glass to peer into once you remove the cathode heater current to stir up the vapors inside for $20/shot.
