I think I've found Maxwell's Demon, however the demon is quite large...

Yes.... Damn I think the picture needs some change, this system will be totally different than what I had mind.
Connecting a bunch of those pipes together, maybe in groups of eight, now that would have been interesting!

I realize I shouldn't be thinking about volume at all when this system is so small and just meant to be tested.
First of all we should try to guarantee a positive increase in temperature, and a couple of these pipes connected together with a little isolation in between is no big hazel to build 

Even if unlikely, I suggest adding a pressure safety valve on the last pipe, just in case steam builds up, though I don't know how many pipes that would be needed to make it happen....

I was thinking PVC pipe, but with one pipe inside the other and using a vacuum in the wall spacing to form a large thermos bottle.

Then just fill the inner tube with water and three thermocouple thermometers, one at the top, center and bottom, shake it up well and see how well it separates.
Once the separation rate is recorded it could be used to calculate any practical application.

So you mean like using one larger pvc pipe to isolate the other smaller one, with vacuum?
Do you not think that any where close to a vacuum would shatter the pipes, since they are only made of plastic?

Was this also what you talked about last time, because I envisioned that you meant almost what I suggested here, only that they were instead placed inside each other, with isolation in between.

Sorry if I misunderstood you, but I just wonder if it will be more practical than having them placed side by side.
If you meant more units in one cylinder then a heat pipe solution would be quite complicated, but maybe that "heat amplifier" you talked about did it in another way?

No, the vacuum idea is something totally different than the other tank inside a tank heat amplifier from the early days.

The PVC vacuum bottle concept is just to insulate the inner tank chamber to get an accurate test of heat separation in the water with the smallest outside influence as possible.
It should not be a problem since a total vacuum is only about 15psi.
