If a create a magic microcontroller that would have 0 capacitance, 0 short circuits and 0 transistor leakage (even when working at full load), does it means it would have a power consumption close to 0 ? (so computation would be free). Am i missing something ?

@tigrou I think that idea is tackled by Maxwell's Demon
Maxwell's demon
Maxwell's demon is a thought experiment created by the physicist James Clerk Maxwell in 1867 in which he suggested how the second law of thermodynamics might hypothetically be violated. In the thought experiment, a demon controls a small door between two chambers of gas. As individual gas molecules approach the door, the demon quickly opens and shuts the door so that only fast molecules are passed into one of the chambers, while only slow molecules are passed into the other. Because faster molecules are hotter, the demon's behaviour causes one chamber to warm up and the other to cool down, thereby...
but important questions become things like "how are you storing data"

Maybe Maxwell's demon is out there somewhere, playing with Occam's Razor?

OK I think got it. Even with a perfect CPU that does not exists I would still have to spent energy for something else (eg: input and output in this case)
