To talk about these things without saying c ... ies, you still have to understand the basic principles.
Could you consider 1 second that we stammer before understanding something?
You just had to explain, if you had understood the operation.
Apart from saying that they are c ... ies, and noting that I used an abuse of language at the beginning, we haven't heard much from you.
to clarify, I was not talking about you specifically.
It's good to know that when you quote me, you are not talking to me.
I quote you and therefore answer you.
If I may, I would note in you a methodological problem: To approach any subject, it is first preferable to seek to understand it before answering it.
But no,
ABC is above that!
The knowledge that you project is possibly outside the domain of validity for the problem considered.
In order to understand the possibility of extracting electrical energy from heat, a very simple method will be followed. In theory and without raping anyone. You will get on with Carnot afterwards if that makes you happy.
In my opinion, I'm not going to teach you anything but you probably never considered this theoretical possibility:
Any electrical conductor subjected to a temperature above 0 ° K,
generates a noise voltage at its terminals.
https://fr.wikipedia.org/wiki/Bruit_thermiqueAmbient temperature is more than enough to generate nV in a piece of copper wire.
This voltage can be measured, it is REAL and it annoys even electronics engineers who want to amplify useful signals and not noise.
I got big IF.
Si we had rectifying components capable of rectifying nVs and without noticeable loss, that would be won.
One could extract electricity from the ambient temperature, without needing a cold source.
Carnot has just made an attack!
Can you imagine the possibility that another system more astute than the one I have just described and technically feasible, exploits this thermal agitation of atoms?
Consider, before saying it is impossible because you invoke physical laws inappropriate to the framework of the considered problem.
So no
Christophe , no more 1 for ABC's spiel on thermodynamics, it is irrelevant, even if what is said is undoubtedly true for a problem other than the one which interests us here (not read in full)
whatever.
