It's interesting that you bring up Thermal Noise... Thermal Noise would indeed have to be considered alongside The Casimir Effect and Capacitance -- because even though Thermal Noise could be reduced by cooling -- it is unknown if it could be eliminated entirely... If these three effects are always present alongside one another in an electronic system, most notably the metal plates of a metal plate Capacitor -- then it would seem that they are indeed related, although, I'll leave it to future Scientists to state that for a fact, and to better quantify the math of those relationships if there is one... Thus, these phenomena should definitely be studied alongside one another... Anyway, thank you for your excellent addition of the concept of Thermal Noise to the discussion!

[Assuming I made no horrible mistake in the GP...] In general, you can make systems that show only one of the effects. * If it's big enough and the voltage is big enough, you can almost get a system that is a classical capacitor, without noise. * If you reduce the voltaje, you may see the noise. You can increase the temperature to get more noise. I wonder if it's possible to measure a Casimir-like effect here. I never heard that, but it looks possible. Anyway, if the temperature is too high you will have some nasty new things like electrons jumping like in a vacuum tube. * If you reduce the size and keep it very cold and apply no voltaje, you can get the almost pure Casimir effect. A big part of physics is understanding which simplifications you can make and how to build a device where the simplifications are correct. Each of the effects are useful, but a device that use all of them is probably too complicated to think about. I wonder if the people building microprocessors have these problems. They have hot devices that must be at room temperature, that are tiny because they must put a lot of them in a small piece. The only part they don't have is the vacuum, so the material between the plates can keep them away.
