Maxwell's Demon Possibility?(Entropy)

AI Thread Summary
The discussion centers on the concept of Maxwell's Demon, a thought experiment proposed by James Clerk Maxwell that challenges the second law of thermodynamics by suggesting a mechanism to decrease entropy. The scenario involves two chambers of gas separated by a gate monitored by an intelligent entity that can sort molecules based on their speed, resulting in one chamber containing only slow molecules and the other only fast ones, thus creating a temperature difference. Participants explore the implications of this idea, questioning its feasibility and relevance to real-world applications. The Ranque-Hilsch vortex tube is mentioned as a practical example of a device that separates hot and cold air through airflow dynamics, hinting at potential connections to the theoretical concepts discussed. One contributor expresses interest in a personal idea related to vortex dynamics that may also address entropy, although they consider it underdeveloped.

"Maxwell's Demon" Possibility?(Entropy)

About a hundred years ago, James Clerk Maxwell imagined 2 adjacent chambers, each containing gas and both sealed to the outside world. The chambers are also sealed from one another, except for a single gate the size of a gas molecule. Guarding this gate would be an intelligence with one power: the ability to discriminate between fast and slow molecules. It would pass slow molecules in one direction only, fast molecules in the other direction only. The net result would, after a time, be one chamber that contained only slow-moving molecules, next to a chamber that contained only fast-moving molecules. In other words, the chambers would not be the same temperature: One hot and one cold. Should such a "Maxwell Demon" prove possible, its discriminatory intelligence would reverse the apparently irreversible entropy, which inevitably has everything existing at the same low temperature? Any Comments?

Have you ever heard of the ranque-Hilsch vortex tube that separates hot and cold air? It operates simply by virtue of the air flow through the geometry of the device.

I have thought about such things, and though the consensus is no, I have a half-baked idea oddly enough also involving a vortex that seems like it would decrease entropy. As it is half-baked I don't care to share it, but if you visit here often I will PM you with the idea, if it proves interesting.
 
Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'
So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
