Unusual design of a free-flow hydropower station
ebastler:
A couple of non-technical facts. Follow the money...
* German Treshchalov, the author whose papers Hydro has repeatedly shared, is not an academic researcher. He has led is own company, ERGroup or ERG, for the past 16 years: https://www.linkedin.com/in/germantreshchalov/?originalSubdomain=uz
* The Youtube channel Hydro has linked to twice in this thread has only those two videos, both put up over the past 8 days. And as it happens, that channel is also named ERG: https://www.youtube.com/channel/UCOTyVjisYjonxLLgKNtsUjw
* Otherwise, ERGroup does not have a lot to show for a company that has been in business for so long. But they will make it big "real soon now"TM, with an innovative energy technology to be launched later this year: https://www.ergroup.asia/
* We still don't know who that mysterious "professor from Michigan" is, whose analysis Hydro has shared three times (and who just happens to publish in Serbian according to Hydro, so we only get censored English excerpts from his work).
And we still don't know how "Hydro" is related to this merry bunch, and what his interests are in all of this. Honi soit qui mal y pense...

One thing that should be evident, Mr. Hydro lacks a certain amount of basic math, engineering, and science background. I'm estimating Grade 10 level math & science.

Relax, guy !
I'm a businessman. I have no academic background. Only technical courses.
When I need it, I hire academics, engineers, programmers.
But it seems that you all don’t even have a technical education, so I definitely won’t hire you.
First does not understand that in order to stop a pulley by hand, you need to know not only the torque, but also the diameter of the pulley.
Another one managed to multiply 3 kW per millisecond and is proud of it.
Hey dude ! Try multiplying it by a nanosecond! You will get 0.000..... 0000952778KWh.
Your wife will be proud of you!
The third already from the first page of the topic threatens to find errors in the formulas.
It would seem that if you see them there, show them to everyone and prove to everyone that this is all bullshit.
But he doesn't do it!
Because there are no errors and therefore he cannot find them!

Absolutely right!
These technologies are not intended so much for Europeans, Canadians or Australians (although for them too).
But to a large extent for farmers in Pakistan, India, China, Africa, and South America.
As we say:

According to the table you posted, such a hydropower station of 1m depth produces 3430 Joule per second. This is 3430W and boils down to 0,000952778KWh. Good luck in powering your house with it.
:-DD :-DD |O

Another factor.
3 kW at with a depth of 1 m (turbine height) is being actively discussed and no longer seems to raise doubts.
A conventional free-flow turbine (Darier turbine or Savonius rotor) under such conditions according to the Betz limit can theoretically produce only 0.5 kW * 0.59 = 0.295 kW
However, as can be seen from the table, increasing the vertical size of the turbine (depth) increases the turbine power in a cubic dependence.
Thus, by increasing the vertical size to 1.5 m, we will increase the turbine power by 1.5^3 = 3.375
That is, up to 11 kW
And daily energy production is 275 kWh!
Is this not enough for anyone else’s home?
