I'm terrible at expressing myself.

The original post contains a diagram that has a battery in series with a green box (anything can be in that box as long as it is not containing energy when connected) and a resistor as the load.

There are two questions
A) Is it possible for V2 to be a constant 30V
B) Is it possible for V2 to peak to 30V multiple times while V2 never drops below 5V ?

And I provided my answer to those questions
A) No
B) Yes

A lot of people seems to agree with me and some do not agree or do not want to provide an answer but ask for some proof my answers are correct.

Here you can see Zero999 agreed with me and even provided an LTspice example (simpler example than mine) still it shows V2 >> V1 intermittently.

Also there you can see a description of how a more complex circuit can work but the idea is the same as in the simpler example provided by Zero999 and EPAIII

My criticism wasn't that you edited your post, but lacked transparency in doing so.

Why did you ask the question if you already knew the answer? It it was a brain teaser, then you should have been upfront about it. Going from your posting history, I think many people here thought it was some sort of free energy scheme.

I'm not the smartest person here. Far from it. I'm sure many others are capable of figuring it out. Indeed many probably did, but didn't post a solution due to lack of will or time.

The reason most people are not responding is because he is not asking the question in good faith. It is, as Simon said, a wind up.

This thread, along with other previous ones, is just a big waste of time.

Sorry for not being clear. Yes it was a brain teaser and I always mentioned that I know the answer to the question I was asking.
I think you are modest. You are sure fairly smart.
I did not asked for a solution if you agreed with my answers.
I asked for a solution if you disagreed with me on question A)

Using an analogy to prove a point is in bad faith ?
