Who can edit my messages and why?

[AVGresponding]

Mods and Admin can edit your posts, and will be doing it because you are posting something that goes against the forum rules.

[Hydro]

Thanx
Is gnif a moderator?
OK, I didn't know.

But I don’t see anything that my post was edited - as I put it, that’s how it is.
It's strange that you could edit there without editing anything.

I didn't read your message very carefully.

Do you think that I am  posting something that goes against the forum rules ??

Please clarify - what exactly?

[AVGresponding]

How should I know? Go read the forum rules, and apply them to your posts.

[Hydro]

I have read the rules and follow them exactly
Therefore, my messages are not deleted or edited.

The admins didn't tell me that I was violating anything.
For some reason you said it.

gnif administers the forum software and database. There were recently some upgrades that might have required fixing some image references in posts, so it is possible that your post was updated to maintain the correct appearance after the upgrade. Just a guess.

Do you have any objections or did you find errors on the first three pages?

The derivation of equations (5) and (6) are incorrect.

Andy Chee, so what's with the errors in the equations?
Have you found them?

As you can see, these equations have been derived by other scientists and in other ways.
Moreover, the basic equation of hydropower is derived from this equation.

Will you oppose the entire hydropower industry?

Which scientists?  You've just quoted Mr G.V. Treschcalov's article again.

As far as I can tell, he was referring to some scientist from Michigan who came up with Equation #3 and the basic hydropower equation that has been known for 100 years or more.

Or am I wrong?

Just saw this sorry. I had intended to delete a different post and had too many tabs open, as such I modified the wrong one. The edit comment is just to state that something was changed, where in reality here nothing was, I just undid my mistake. Sorry about that.

No problem.
Looks like we've already sorted it out.
Thanks for the apology.

Based on the lack of objections, I can conclude that I am right.

By the way, I think I found that article by a specialist from Michigan who derived the equation.
Strange, but it is also in Serbian.
I'll try to translate.

This is how the translation from Serbian turned out.
Google doesn't translate better.
But it seems clear.
Any objections?

Well, the opponent was  finaly blown away.
Andy Chee still haven't found the error ?

[AVGresponding]

I think he just doesn't see the point in answering you, given you clearly are not able to understand the maths involved. Feel free to continue your pointless spam posting of this technology, but no-one on this forum will give you any money.

@mods, surely this nonsense belongs in the dodgy technology section, along with solar roadways etc?

[Hydro]

Are you his lawyer? Is he not able to answer for his words himself ?
It is not me who needs to answer, but those specialists who compiled these articles and derived the equations.
One of them, as far as can be seen, is an employee of the University of Michigan.
Do you think that they also understand things worse than the clowns on this forum?

Feel free to continue your pointless spam posting of this technology, but no-one on this forum will give you any money.

Open your eyes - I'm not asking you for any money.
And that is not the purpose of the forum at all.

@mods, surely this nonsense belongs in the dodgy technology section, along with solar roadways etc?

So you don’t even know what we’re talking about?
What are you doing here then?
Do you work as a lawyer here?

[Hydro]

 Feel free to continue your pointless spam posting of this technology,

By the way, the good thing is that you understand that this is technology, and not mere chatter.
This is already a progress in your understanding.

[Kasper]

Well, actually, for now I’m only talking about the fact that - Behind the turbine, the water has a speed 2-3 times greater than the flow entering the turbine.
How can this provide power and also accelerate the flow?

Here's another video, it's more clear here.

First, define 'speed' and also 'flow'. 

Then ask, how can current output from buck SMPS be higher than current input?

[Hydro]

What is "buck SMPS"?
What do you mean by "current"?
Who should I ask?

[Kasper]

Buck SMPS is an electronics circuit.  Plenty of definitions on google and probably in the beginners section of this forum.

[pcprogrammer]

Based on the lack of objections, I can conclude that I am right.

I did not want to participate in this thread, but boy is someone here full of himself and blind for what is obvious.

The fact that you can't even see analogies between different technologies proves the above.

There is no need to go deep into the given formulas, the real world test shown in the first video you presented gives enough evidence that it does not bring what is expected. The mechanism is stopped with little effort of the guy in the water next to the device, so how can it then drive a generator to provide several KW of electrical energy?

But my conclusion of this whole thread and the other one about the use of waterwheels is that you are an attention seeker, and most of the frequent users of this forum don't want to play with you.

1. There are definitely analogies between electric current and water flow. But they are never complete.
This is exactly the case if you haven't noticed.

2. The video shows a turbine with a height of 50 cm. If you had bothered to delve a little deeper into the topic, even for a minute, and did not make hasty conclusions, you would have seen that as the height of the turbine increases, the power increases to the cubic degree.
Look here https://www.eevblog.com/forum/chat/unusual-design-of-a-free-flow-hydropower-station/msg5281537/#msg5281537
Pay attention to the numbers on the tables there. They are even specially allocated for you.

3. I don’t need your attention and I’m not going to play with anyone. But you still play...
But I’m not dragging anyone here on a lasso.
If you don't want to play, pass by. The topic about cats is just for you.

I don’t know why you suddenly decided to talk about some kind of money, although there was not even a hint of this in my messages.
But you intrigue me. I'll think about it.

In the meantime, you think about this.
Your consciousness has already reached the understanding that this is technology.
Your consciousness still needs to take a tiny step to understand that this is not just technology, but a highly effective and promising technology.

But don’t tense up and relax - your consciousness itself will take this step to understand the essence of things.

This is called "Overton window".

Again.
This gives someone the false impression that I need some attention.
I repeat - I don’t need the attention of amateurs and clowns !
If you are not able to carefully read at least the essence of the topic, and you have nothing substantive to say, then it is better to pass by.
