I think the forum is not to convert people from the wrong path, but to explain to them the details they ask about.
In the course of such, even stupid questions, you can learn a lot on other topics, and at the same time everyone broadens their knowledge on various topics.
The whole device may be a fiction, but checking and investigating details often leads to a better understanding of other accompanying phenomena, and thus to their use in completely different fields.
So generally speaking, such topics are not completely meaningless.
Provided that factual answers are given.
Based on my own experience in construction work, I know that often an apparently stupid idea may have an ideal application in a completely different field or situation.
You would be surprised if you had the opportunity to test at my construction sites how a combination of several different "stupid" ideas and pain simple ideas can facilitate the work and achieve long-term results better than professional and standard methods.
Added after 17 [minutes]: Don't write that something is impossible. Provide your version or calculations and at best add that according to the current available knowledge, the calculations do not match, and if you see any arc that can be checked, then a hint, where to look for inaccuracies or disagreements with the way of calculating the detail.
there are often combinations of phenomena that cannot be calculated with known formulas, but one could, for example, modify these formulas, if only by trial, to see what will come of it.
You have a lot of knowledge, but as if you are afraid of the results of its exploitation. :-)
As far as Pinocchio is concerned, you have to decide whether rapidly taking his dreams away from him is better than teaching him gardening slowly. :-)
Added after 31 [minutes]: If this forum is to serve as an advisory board, it means that it has an educational form, so any non-educational statements should not take place.
There are no stupid questions, but there can be stupid answers.
