Love the video. Thanks a lot. Looking forward to more

Why would you dislike this video, what’s wrong you people??? This is some hard work put together come on!

Excellent thanks

The efficiency of these machines is truly amazing. There are some historic mills still operating on hydraulic turbines.

Just a note re: the dam shown 7:00 of the video. The water going through the dam is being spilled - no generation. It's a flood control dam. The photo partially shows, in the right foreground the power station which was built over 40 years later. I really liked your video and it brought back memories of that dam being built. My father was the project manager.

Great presentation. Thanks👍🏻

thank you, very good presentation, and very explanatory.

Thank you so much for the information.

Hello John love your videos

Very good video

Please make a comment here to request a tutorial video for a specific machine. Add a comment, otherwise I don't know what to do next! 😀 Thanks!

Thank you so m uch for making this video.

Good video

Very good presentation and very explanatory! My questions to you are the following: I want to build a hydroelectric system and It's my understanding all these turbines might come in European or north American voltage which is 110 V. In Africa, especially where I am trying to install one of these turbine, we use 220V. Do you think I should be mention it to the manufacturer about the 220 V? do you know places I can get 220V turbines. Which turbine do you suggest and they must be expensive as well. I'm trying to build the system in a river and also a place where there's only a well. I'm also thinking of adding a transormer, breaker, may be an inverter. Please advice. Thank you again for your help.

I really love this vídeos,,,,,,,,my memories ,,so good

Thank you!

Thank you very much!

Great vid. So if I wanted an inline turbine in my shower hose to power leds, which would i use for best efficiency. presumably the pelton/impulse given the pressure, but its unbroken flow so that would suggest one of the others - bit confused

Excellent

I would be Interested in an analysis of the use of an Archimedes type Screw as a turbine In a Lo head application. I am presently using a post hole digger augur with four flights inside of a six-inch pipe with about 15 feet Of head In a Vertical orientation, mainly because of the availability and price of the auger as a turbine. I am getting somewhere between 1500 and 2000 RPM. With enough force to drive an alternator to give me Around 300 W. Or so. Very inexpensive to build and quite easy as well. A Francis turbine would be ideal but hard to find and expensive.

Hello, I am doing a thesis on hydroelectric power plant design, but I could not find a clear enough source. If there is a source that explains the principles of hydroelectric power plant design step by step, could you suggest you know?

Good Video! Can you do a video or model about that crossflow turbine? I never saw that model before...

+Rafael Schimuneck I will try to make a model and video over the next few months. There will hopefully be one model and video for each turbine (at some point). The plan is to make a video a week, so stay tuned! ;)

Pressureless turbine would be the least efficient due to frictional losses and broken linear water flow. I would believe that the Kaplan turbine is the best for efficiency, assuming enough flow rate.

Where could I learn more about the three types of turbines and more on the hydroelectric front? I’m study for an DWR apprenticeship exam so any advice is appreciated!

May i know the warnings and safety instructions?

Good video for choosing which one to use . Not common , and not sure of claims . But if possible , I would like to see if the Tesla - boundary layer turbine can be tested & compared on chart .

Thank you very much

You are welcome!

No mention of the Tesla turbine? It sure would be nice to see how it fits in your graph.

Thanks. Check out the new channel for more videos.

You can increase the penstock pressure double by a jet theory to the Pelton turbine

What would happen if I use a kaplan turbine in a high head and high flow situation, would it still perform well?

Cavitation - likely catastrophic. That's why large ships have such large propellers - same problem.

gud job dud.

What makes the vertical Kaplan different than the horizontal?

@nedegt1877

Higher flowrate, thus more efficient above 20 Meter Head of Pressure. Lower Head of Pressure is the horizontal more practical. But the turbine it self is no different. Only how you install it.

I believe pelton wheels are different from and should never be called turbines since they operate at lower speeds and efficiencies . . . Peltons are more akin to water wheels as such . . . So it goes ! ! ! - Kurt Vonnegut - Slaughterhouse Five -

What about Tesla turbines?

Your slide shows a "WICKET". I think it supposed to state: "WICKER".

RDP Marine Australia for the new multi stage turbine update systems

😊 🫂 🙏

You write kw / hr when you mean kw hr.

Why are there no multi stage turbines ?? Answer the tech is available from RDP MARINE AUSTRALIA The techs will say the issues are turbine surging OR to much backpressure OR the dissolved gasses issue ALL are nonstarters So were is the price drop you can have by fitting this item ?? YES YOUKNOW WHY
