Then why are you here asking what you need?I didn't ask what was needed for this.
I asked what it would take to start a campaign.
Does anyone here have experience?
So we are the first with our know-how and it will be cheaper with us.
Just tell me where and what button to press to start the campaign.
Do u know that ?
Yeah, it seems we to have figured out how to start.
The boss asked me to create a start page on Indiegogo for one of our projects.
Has anyone used this platform?
Can you give any useful advice?

1: Indiegogo is responsible for so many scams and unfulfilled 'products' over time with 'backers' (not customers because that is not guaranteed or even a requirement) left out of pocket.
2: The fact you are here in public asking how to go about it shows you are secondly fundamentally unqualified to execute 'the boss's request' and put your name to it.
Suggestion is find a job you are better qualified and have the skills to do.
Could you describle the energy flows of your solution with some few simple maths please ?
I don't specialize in this, but it seems to me that everything is quite simple here
1. propeller with a diameter of 0.15 m and an area of 0.018 m^2
2. water speed 3 m/s
3. power 80 watts
4. for 10 hours 1 kWh
error 15%
enough ?
They asked for math, I gave it.
They asked for math, I gave it.Hello, a Pleton impeller would give a better efficiency even without injectors...
but the real problem is the resistive torque of your generator, have you calculate it ?
Hydro is that you again?
do you understand well what you are talking about?

enough ?Whoops, we didn't know you were making a water turbine. To efficiently extract energy from an unconstrained axial turbine in an incompressible fluid like water you need blades shaped like a boat propeller rather than an aeroplane propeller, and a lot more blade area relative to the swept area.
Also, immersed generators are problematic. Maintaining a watertight seal on a rotating shaft long-term, that will stand up to the abrasion of possibly silty water is *difficult*. To avoid significant loss of energy, smooth flow over the generator body is desirable so it must be well streamlined.
Lastly 3m/s is nearly 11 km/h, a flow velocity that can typically only be found in mountain streams, rapids, and fast flowing floodwaters, and it will typically be impractical or dangerous to camp close beside them while your USB device charges, and certainly not good for your phone to attempt to charge it in the splash zone!

Hey Sergey, interesting to see you back.
I am not sure whether it is acceptable on this forum to re-join under a different account name after you have been banned. You might want to seek approval from the admins, explaining why you consider this appropriate.
Hydro is that you again?pardon ?

He asked a very reasonable question. Considering you're the same human behind both accounts, do you want to look silly in front of everyone and pretend you're someone else, or are you going to admit that you created another account after you were banned? Decide carefully because my tolerance for games is low today.

Just penpals from your earlier visit here as "Hydro"...
It's a step in the right direction that you now disclose your affiliation with ERG, rather than trying to act as an undercover claqueur. Like Halcyon, I would encourage you to be open about your background and intent.
In that spirit, could you clarify your location? You claim to be US-based, both in your forum profile and on Indiegogo -- but actually seem to be based in Uzbekistan?
I don't know you. I don’t know your last name or first name.
If you corresponded with someone from our team, then obviously not with me.
And your statements look strange. If a Microsoft employee writes to you, will you be sure that Bill Gates is writing to you?

I don't think you need to know my name. In contrast to you, I am not running a crowdfunding campaign and pitching it here.
Since ERG is a tad smaller than Microsoft, I do indeed assume that "Serg" from ERG is Sergey Shevtsow, their "Chief Product Officer". If I am mistaken, feel free to correct me. And no, you and I have not corresponded via email or such; just discussed here on the forum when you were registered as Hydro. (Which you were, right? You have not commented on that yet.)
Thanks for the clarification regarding your location. I'll take your word for the US entity, and would hope that Indiegogo verifies such things. I never understood why those seeking funding on that platform don't have to disclose their company details to the audience of potential backers; but apparently that's how they work.

ERGroup is much smaller than Microsoft, but has employees and volunteers. Don't you think that I myself translated the subtitles into Arabic, voiced the text of the video and did the accounting?
Yes, my name is Serg, but my last name is different, SergeyShevtsowShevtsov - CPO, I am a programmer, web designer
I don't know what you mean by Hydro. Has anyone registered under this nickname? Please clarify.
I don't care whether you take my word for it or not. I don't have to answer to you for this. Especially without knowing who is hiding behind this strange, meaningless nickname.
We do not seek funding on this platform.
We are looking for funding on the Kickstarter platform.
This platform is used for public opinion research, information and feedback. As far as I understand, this is what it is intended for.
In conclusion, I will say a proverb in our language. I don't know if the translation will be accurate, but try it yourself.

ebastler makes sensible points. YTA.
If you want people to invest their money in your company, it is necessary for you to be open an honest - about the technology, its performance, its state of development, the company, the country, etc etc.
Adding an untranslateable/ambiuguous proverb in a language that gurgle (mis)identifies as Kyrgyz is not a good ending point.
....identifies as Kyrgyz
It's clear. Thanks for the detailed explanations.
They require a detailed answer.
I won't have time today. And I need some advice.

Not in that video there aren't.
It is stock footage of windmills (etc), "hooray" advertising slogans, cartoons, and zero technical claims with any substance. Classic example "80% more efficient than existing similar devices". That statement could be satisfied if your device generates 2µW rather than 1µW.
Don't forget that we are engineers, and that means a standard part of our everyday job is to assess what isn't being said, and to weed out advertising bullshit. That's why lawyers (allegedly) don't like selecting engineers for juries
Can I suggest that in the near future you add your device and campaign to this thread.
[...] you launched into some kind of personal showdown that I’m having a hard time understanding.
Talk is cheap. Show us the numbers. Every project like this is considered BS until numbers are presented. Demonstration of a working prototype is also a requirement.
[...] 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.

https://www.eevblog.com/forum/chat/unusual-design-of-a-free-flow-hydropower-station/
There was another one in the Crowd Funding section, but I think that got deleted entirely.
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
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.
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.
i quickly looked at your link TL;DR - som kind of nonsense. Some kind of incomprehenible design that has nothing to do with ours.
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?
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?

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.
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.

For some personality types like mine, this is very important.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.
