You (or, for the sake of the argument, let's say "someone") registered as "Hydro" a couple of months ago, presented the same technology, and also looked for "feedback"

Where is it ? May I see it ?

Oh, now you have convinced me that it's not you and you have never seen that thread before.

There was another one in the Crowd Funding section, but I think that got deleted entirely.

[...] you launched into some kind of personal showdown that I’m having a hard time understanding.

Let me try to help you understand... This topic has a history here. You (or, for the sake of the argument, let's say "someone") registered as "Hydro" a couple of months ago, presented the same technology, and also looked for "feedback". Hydro took the unusual approach of hiding a lot of facts he wanted feedback on, and generously dishing out insults along the way. While it was amusing on some level, it also caused a lot of aggravation.

We would like to know why we can expect better this time. Is this new incarnation of ERG going to be civil, sincere and open?

You are not off to a great start with this "who the heck is Hydro?" approach. We can all recognize writing styles; moderators can also compare IP addresses and presumably other user fingerprints. Halcyon, who is a moderator here, has already confirmed that you seem to be the same person as Hydro.

If you level with us now, you may still be able to turn this around.

Based on his current responses, he won't be able to turn it around.

Bad starting continuing points: bluster, not answering questions, and trying to deflect conversations away from those questions.
There are lies, damned lies, statistics - and ADC/DAC specs.

Let's see what Halcyon thinks once he checks back in. It seems that he has looked into these two user accounts, and had specifically discouraged the behaviour we see now.

i quickly looked at your link TL;DR - som kind of nonsense. Some kind of incomprehenible design that has nothing to do with ours.
i havn’t loked further yet, I don’t have time yet.
here is a link to tje draft aplication.
https://www.indiegogo.com/project/preview/157eeca6#/faq
there are links to articles somewere in the texts. you probably need to read them too.
if you have any questions, writ e them here, and when i’m free, ill come in and pick it up.

How much electricity does it produceat a current flow of 1 m/s, 2m/s and so on?
Standard free-flow turbines are efficient only with water flow speeds of 2 m/s and higher. At a speed of 1 m/s, their efficiency decreases eightfold! Our turbine has high efficiency in watercourses slower than 2 m/s. More detailed information is available in the text

sounds like you are quoting fan laws there, or the laws that apply to actual turbines, sure they apply to these paddles too?

Quote
Will the turbine harm fish?
Our turbine does not harm the fauna of rivers as it does not completely block the channel and makes only about 20-30 rotations per minute, which is dozens of times slower than the propellers of boats, ships, or traditional hydro turbines. For fish, this turbine will be similar to a natural obstacle, such as a small island or a waterfall. On the contrary, our turbine will additionally aerate the water which is beneficial for river fauna and flora.

So you have not studied existing turbines like say the ones used in dams, they also do not harm fish, so why is yours special.

Quote
What is the power capacity of your turbine?
The approximate power capacity of the smallest unit is 3 kW. This allows the generation of more than 70 kWh of electricity per day, which is enough to power two to three large houses.In this case, only additional technical means are needed to compensate for peak loads.

be careful. Lots of dodgy products like to claim their 24 hour output for bigger numbers. the standard is kW, stick to established engineering standards, it looks less like you are running some scam then. Chinese wind turbines off amazon anyone?

shall I go on?

 :-DD

So you're saying the fact that this site which is also called ERG, and which also used many of the same graphics as you do, and also does the same work, and was used by Hydro to post files here is all purely coincidence and his posts were nonsense but yours aren't?

And strangely, Hydro even shared his water-power videos using the same "ERG" Youtube channel which Sergey has now advertised. Hydro's old videos have been taken down, but the fact that he used that channel is still documented in the old thread.

Sergey, dear -- you had a chance to own up to the "Hydro" episode, but you have failed epically. How do you expect us to take you seriously and trust you now? Time to say goodbye and come back with a third account in a while...

Wouldn't it be funny if this guy was actually a completely different guy who is really genuinely SUPER EXCITED ABOUT MICROTURBINES!!!!!!!!!!!!, and it's a just a coincidence that he showed up here when he did? 

Should I ask for his help on my MARS ROVER for MARS!!!!

Funny; I am staying at a friend’s home, and on the YT channel TechZone, there were these ERSTREAM water micro-turbines casually being shown as I was reading this thread!

They mentioned that the kickstart fundraiser was successful.
Among the suggested applications were charging cell phones on the woods.

The Principal does have some technical credibility on an ability to design this. BUT the overall premise was based on over inflated claims using unrealistic physical factors showing it was 'perfect' to release and market it on Indiegogo along with a false flag to compound the fake beginning.

Technically this will work but the reality is the power output 'claimed' was based on a near flood water flow speed, the simple reality is water flow much above 1/3 of this you would want anything being powered 10+m away minimum. If you do some basic calcs then at the initial claimed power and flow rate given then the actual wattage from a 150mm impeller is well within range and a sensible efficiency. Power output at a reduced velocity falls off dramatically at these lower speeds.

Practically the 'idea' is a flawed one as it only works in a very small subset of locations used by Campers and Water (kayak, canoe etc) users. This is going to be compounded in a stream situation with getting the turbine out into that stream and tethered in place and held above the bed without chopping down a forest or finding that miracle downed tree in just the right spot. Towing is behind you is just DUMB if you have ever done any flat water paddling the last thing to want is a Sea Anchor  :palm:

So this thread should stay in part as a warning to ANYONE thinking of backing a microturbine project or anything put up by the Principal Treschchalov German or his companies including ERGroup.

This is what I really like about the moderation here.  Nothing is ever perfect, and if one admits to an error, and promises to not repeat the problems in communication, they can get a second chance.  But, if they do not and just repeat by creating a new account, they get banned.  This is how it should be, because as humans, we make errors, but can also change how we interact with others.  (Using a pseudonym helps with that, because it reminds one that others do not react to your person, but to your output.  For some personality types like mine, this is very important.)

There is obviously something fishy about the project this thread is about, because of the games with the poster identity.  We cannot know whether it was intentional (as in trying to use EEVblog forums as a harebrained way to gain credibility for something the authors know is basically doomed to fail), or unintentional (someone so blinded by their own idea that they cannot communicate about it without sounding like a single-minded fraudster), but the whole scheme reeks of something rotten underneath.

There are lots of projects for small-scale damless hydropower, from waterwheels to underwater stream turbines.  The common factor in these is that only a tiny fraction of the energy in the water flow is harvested, so the stream/flow is minimally affected; plus the electricity output is very modest; overall, comparable to smallest wind turbines.  There is nothing wrong in starting a yet another project like that, but you do need to 1) do your background work diligently, to find out about similar past projects and their wins and failures, and 2) be open about all that.  None of this will be a huge commercial success, because the field –– hydropower in general –– is centuries old by now.  Everything easy or simple or obvious has been done again and again already; any successful product will have to combine the best features of both existing designs and existing manufacturing capabilities, to be successful.  The project here did not do either.

(I have done some online research on underwater flow turbines, but their major problem is that any debris or water plants tend to clog them up.  My root idea was a hubless turbine with permanent magnets at the tips, and the coils in the enclosing double funnel tube.  For something like charging your phone from a small stream for the night when camping/trekking it should work (with very limited electricity output!), as it ends up being cleaned daily, but for anything longer-term, they just are not suitable.  My own conclusion was that a portable wind turbine would perform much better, especially if you could prepend a hand-cranked gearbox in front for emergency charging.)

Hear, hear! I don't always agree 100%, but it's worth taking the chance to recognize the efforts of the mods. It's absolutely not an easy job, and their work is appreciated.

I'm of mixed feelings on this... I get that it's helpful to you, and many others, but there also seem to be plenty of people who just take the opportunity to treat it as a "disposable" identity where they can say things they shouldn't and wouldn't otherwise, because they don't fear any permanent/IRL repercussions.

True: that is the negative side.

Similar issue exists in real life too, when people see others as part of a business or machinery instead of people, and/or rely on anonymity to shield them from repercussions, when they do stuff they'd never do to people they know.  This shows up even statistically: in urban environments, certain types of crimes like theft increases superlinearly –– more thefts per person –– as the population size increases (source).

In my own case, and most others who I believe use pseudonyms in a similar, shall we say 'positive' way, are heavily invested in them; they are definitely not disposable.  Perhaps not as permanent as ones legal name, but definitely not disposable.  For me, it is the identifier for my output I want to use long-term.  For example, I've had my own matching .net domain for over a decade, in the hopes that someday, I would be ready to put some of the stuff I've created there for others to use and learn from.  As of mid-March 2024, after doing some quick web searches, all occurrences of 'Nominal Animal' as a username or pseudonym I could find, do all refer to myself.  Or specifically my own output, rather.

I bet this would be a very interesting research subject for someone interested in psychology/anthropology/history, because we can see the same in most creative industries across history, especially with performing artists.  I suppose it is how 'brand names' originated, too.

There is a reason people like to live in the countryside or villages. The only reason most don't is the price or the inconvenience as services are more limited and it's more isolating. But it's that isolation (low numbers of people) that bring people together.

We had no moderation at the start on here, or rather no official moderation. Some of us and I was one would wade into the rare arguments and try to get the two parties to be amicable as users. Yes it got harder as an official moderator as we stopped being that cozy community and were much bigger, the anonymity factor kicked in and the official establishment to hate come into being. I miss the days of it being a few hundred users and no moderators. We actively tried to get along as we all knew each other in the much smaller community that we were.
