Smoluchowski's Trapdoor

Charles M Brown: For Smoluchowski's trapdoor, a gas molecule that pushes forwards through a trapdoor into the more crowded volume is not being compressed and getting warmer; the opposite is happening. First a gas molecule in the less crowded volume side adjacent to a trapdoor receives temporarily high momentum from the thermal momentum that is passed around at random. Next it expends its momentum pushing through this adjacent trapdoor where the trapdoor transmits a counter pressure from the more crowded volume that the trapdoor opens into. Approximately meanwhile the trapdoor is in the way of gas molecules near the trapdoor on the crowded side because the door frame blocks the trapdoor from swinging past the closed position the wrong way into the less crowded side. When the correctly arriving gas molecule carries the trapdoor open wide enough, the fluid molecule continues into the more crowded side beyond the trapdoor traveling with any remaining momentum. It has lost momentum so it is colder. The gas molecules on the more crowded side sent in by all the trapdoors in the array eventually drive the return turbine which produces an output of mechanical work and regenerating the less crowded and slowly moving gas molecules similar to the one we started with before it received a dose of thermal momentum.

Beating the wrong parts of the theory to flush out answers won't satisfy questioners concerned with non beaten parts of the theory; the theory has to be beaten everywhere for everybody. The issue is very important.

The heat absorption of microfabricated prototypes is expected to be very small because the performance is limited; nanofabricated prototypes producing large amounts of electrical power should produce correspondingly large amounts of cooling. If an initial large electrical output is observed on a nanofabricated prototype heat measuring instruments will be installed and activated.
