The problem I have is that I fail to see how it caused so much consternation. The way I understand it the demon could passively allow or not allow particles of gas to pass or not pass, and thus gradually create a more ordered state free of charge.
I have learned that the problem with the demon was 'solved' because it had to keep a tally of what it did and eventually this information needed to be erased in order to store more information and the erasure caused heat and there fore entropy to be increased.
The problem I have is that even before the above, would not the demon be generating heat anyway merely by opening and closing a door or somehow directing particles. Why is it not sufficient to say that the demon was using energy in order to create more order? It seems obvious to me but I must obviously not be understanding something because I'm this would also be obvious to the people in the 19 century who were worried about the demon.
