The $50 Water Turbine - DIY, Portable, Powerful, and Open Source
Вставка
- Опубліковано 2 гру 2019
- For less than $50 you can build a low head, medium power, super low cost and low tech hydro turbine.
Can be plugged into any appropriate waterway, uses only basic off the shelf and recycled materials, and simple hand tools.
Aiming for 200 to 500 watts of power/ 5-12 kWh per day from 2 meters of drop at about 50 liters per second.
This technology was produced in partnership with COACT, an open source green tech incubator in Barcelona. COACT exists to help all kinds of innovators working on green technologies. To learn more, and apply for a residency visit www.coactlab.org
And thanks to the good people at Ca La Fou (calafou.org/) for the rest.
Once the design is optimized I'll produce a full open source construction tutorial on
the website: opensourcelowtech.org

The aim is for everyone everywhere to be able to build and maintain their own infrastructure; producing their own energy, food, clean water, communications, and anything else they need.
All designs are open source and license free for any purpose, and full construction tutorials and how-tos are available on the opensourcelowtech.org website. - Навчання та стиль
people like you, who use their knowledge to better the wold for free with open source project are one of the few reason i have not lost all hope for humanity. thank you
I was just thinking exactly the same thing 👍
@@andreihossu2749 i do not praise him for making the best most efficient desing, i praise him for doing it free, for the benefit of mankind.
science if full of idea that have been paused and given more interest after. it's also full of idea beeing halted, but the motive for that stop is not always ineficiency, it can be lack of interest, death of the inventor, conflict with lobby,...
in medecine phago therapy came up befor vaccines and yet it was left behind because it was not easy to mass produce, but now that antibiotics have been overused we see it as a new miracle while it is old tech. the electric car also came before the fuel one.
even if it's not the best use of energy (because i agree it's not using the whole potential energy) it could be usefull some place
also people have already pointed out that he should use a load to see the real power of his engine. he didn't say it was the best or that he was the messiah as you seem to think
Sad that our power companies won't buy power generated like this otherwise thousands would be doing it.
@@andreihossu2749 yeah yeah you're not extracting the full potential energy with that kind of device, i can see that. but that might be enough for lights in a small house and it's easy and cheap to build.
i'm sure in some place they would already be happy with this kind of powersource
(plus i've never seen a motor working this way, it's interesting)
@@andreihossu2749 Hopefully you can save the world with your vast knowledge, unfortunately I think your pessimism will keep you from trying anything.
Thank you sir. I decided to move to rural South America to get away from civilization but after some major flooding I rejoined society, albeit in a different way. I started a "critical skills club" in rural Chile and invited many to come build many dozens of these based on your design, we ended up scaling them up in size and capacity, so 30 separate turbines became 12, and then 6, now the entire village has more power than we know what to do with and we are helping many others in the nearby region to do the same. Much love, you helped a lot of people. Damn solar is too expensive and too hard to make raw material wise, THIS is the perfect idea. With the power we were able to maintain palliative care services at a nursing home, you literally saved dozens of lives.
Hey, that's amazing, do you have more information / data / media of this?
Please tell us more! Would love to see pictures of what you did!
He's like Doctors Without Borders but the green energy division. You have inspired me sir. I have water behind my house and I'm thinking of 4 of these in a series would end my dependence on the grid.
A big drop is necessary too, I think. Two meters is tough to come by where I live.
I've seen people do this method with even less steep of a drop, but they used a machine to begin the syphon initially so the pressure was crazy high
Engineers without borders is a thing. Also, as it happens, clowns without borders.
Good to hear it’s about 50% efficiency. That’s pretty good considering the simple to make design using off the shelf parts that were not designed for super efficient hydro generation.
I’d like to make one for camping.
wow never seen a siphon style turbine before.
do you think they're generating power legitimately already downstream, behind this guys camera?
siphon between farm ponds, back and forth, as long as the outlet is longer than the intake it will work.
Dan Di you can only siphon from a higher elevation to a lower one. Never the other way around. Really, this is a gravity powered generator.
Siphon type is highly inefficiënt. It can only achieve a vacuum at the low pressure part of the generator.
Pressure difference over the pump will always be less than 1Bar.
Mounting the pump at exit of the pipe will give extra energy. Certainly when height difference is more than say 10meters
@@fransmulder9326 I think it was done this way to make it easy to test in the area he was given. I liked the design because it gives me other options in some unseen future.
Daniel congratulates you for your initiative.
The world needs more people like you, who help by doing, showing how to do it and not charging for the teaching you give.
God bless you. Jalmar from Brasil.
I love this stuff this is the kind of things that can really change peoples lives
Please show how to build
This is the stuff my father taught me growing up to build
Really excellent work, guys!
This is really important work you're doing, which will have significant benefits.
Someone give this man some funding , let him build a water tower and watch him light up a city. Great effort keep up the good work, the world needs more people thinking like you
So, first off, this is a fun little contraption that does indeed have real-world applications, so keep it up. This is the first time I've heard of this open source project, but I think I might like to get involved! Anyhoo, others have mentioned a few issues here and there, and things that need to be considered, and I'll just throw a few items in here as well (some of these may have already been mentioned in other comments):
1. Any air drawn into the siphon tube will want to find a place to collect. The longer your discharge tube, the greater the chance that some of the air will be trapped at the top elbow. A "band-aid" solution to this problem is just to add a large air-gap reservoir at the top where you've placed the cap. A long term solution would be to use a small take-off siphon line to develop vacuum in a smaller diameter pipe along with your main discharge. In this way, you could create an "eductor" (yay Bernoulli's principle!) which draw any air out of the reservoir, thus preserving the main siphon.
2. Your impeller is one of your major bottlenecks for producing max, continuous power. One solution might include a multi-stage impeller with stationary blading in between. This will maximize torque if you get it right.
3. Blade seals - I'm not sure how you would do this simply and cost-effectively, but the trick here is to prevent any flow from passing the impeller blades without imparting any force. Typically, a labyrinth seal is used for this, but I don't know if that's easily applied. Perhaps someone could come up with something via 3D printer.
4. Suction screen - you don't want to accidentally suck up large objects which could damage your impeller. You need to put a large screen at your suction - larger is better because you will want to compensate for partial blockage in the event something gets stuck on the screen. Simply having a section of your suction piping that has a zillion holes drilled into it, and a capped off end would work.
Eeeeeeee e eeeeeeere la ee de los de ee
Somebody understands what's happening. Wonder if they have a channel on youtube with a 3-d instructional video? I guess I'll go searching now.
@@aicram62 I don't, although I've considered making vids like that. So far I only have videos about growing exotic peppers lol. I'd be happy to explain any part of what I said (or any other principle in this family of physics) if you have questions. Also, I'm 100% sure there are other people who have great explainers, too.
Governments could make available injection moulded turbine blades, perhaps in glass-reinforced polypropylene. Also, a blade design that could be reproduced locally with simple indexing lathes would allow villagers to make lots of blades and rotors. Really the blades could even be carved out of wood.
@@MichaelIreland Thank You I'm still feeling out options so I'm not ready yet. I was just impressed with your reply.
THis is so satisfying. "Free energy". Also the priming part was super satisfying.
Speechless!!! Men as you, will made this world a better place where live! Awesome job!!!💪☮️
My hat off to you sir, respect.
I am fascinated by the way people are reinventing the hydropower systems. Most of this was done in the late 1700's for mechanical power and around the late 1800's for hydroelectricity. The major difference between then and now is really lower power levels. Now 500 Watt will provide a lot of light and communications. I strongly suggest finding a copy of a 19th century Water Power textbook. It should be very helpful.
You are a great guy ... love your spirit ... thanks a lot for being selfless ...something we have lost in this world
Really cool! Can't wait to see the final version.
Love brother!!!😍😍👍 Well done!!! You have just given me some ideas. Thank you very much!!! And keep up the good work!!!
such a simple design yet its so efficient. wow
This is exactly what i was thinking of for getting power when on camping trips, thanks for the knowledge!
You are a awesome person, as are all ppl who were involved in this open source low tech turbine.
Especially the cameraman, cameramen in generall deserve more praise.
Definitely subbing your channel & looking forward to more ingenious stuff like this.
Documentation crew are so often overlooked, yes. Thanks.
I like the whole idea of winning free energy from the nature. Keep up the good work mates.
Muy bueno felicitaciones por el proyecto ! Siempre me interesó la energía renovables y todos estos campos es muy interesante saludos desde Argentina 🇦🇷👏
This is great work for humanity you open source people. What a great Vision it is, IF this technology gets adopted as well as optimized for people in remote rural communities. Great Humanitarian folks! you deserved all the love in the world.

Amazing stuff! I'm preparing to live off the grid and was looking for a cheap reliable water turbine to power some of my appliances. Thanks for sharing this awesome water turbine with the world
How is it going
J1 & CHP it's been a learning experience good days and hard days but all and all I'm glad I've made the decision do this currently living out of a waxed canvas tent have most of my electronics and my led lighting running off solar and the more demanding things like a small fridge and a back up generator I keep charged off of the turbine found in this video, for anyone thinking about doing this I strongly suggest giving it a try its hard work but its very rewarding, you know the feeling after a long day at a 9-5? the exhaustion you feel after working on building your homestead knowing all your hard work benefits you and your loved ones it makes you feel good as you sit back and look over all you have done. considering starting a vlog series about my experience.

Hello Daniel is very nice to see A light of hoop in the work that you do we need more people in the world with a heart like yours.
Hi all. Been getting quite a few queries as to how the turbine is developing, which is good to see that there's a high level of interest in the project.
I just shot the next update video yesterday, will edit and release that as soon as I relocate from Berlin back to Scotland later this week.
In short, it works, produces a decent amount of power (full details in the next video), and I'll be doing longer term field tests and a full open source construction tutorial imminently.
Hello sir, can I use your idea in creating my research project and papers? I am really in need of your answer because without your consent, I will be marked with plagiarism in my papers. Email me at my account😊. Thanks in advance❤
@@barbequesaucy967 Everything on the channel is open source, and can be used for any purpose including commercial.
So please do.
Thank you very much sir! I really like your work and appreciate every help you gave thanks a lot and I hope more people get interested in your project that you've been doing it is really innovative and helps the people and the environment. Keep up the good work and God Bless you❤😊
Sorry, I didn't see your update notice a few comments back.
Nice system! I'm interested in trying something similar to power an RFID system. We previously built a high-head, low-flow system with the 5-gallon-bucket design, and later rebuilt it with a real Pelton wheel. I've got a few videos about our system on my channel. We moved to a site with a weir that might make a low-head generator like yours feasible, especially with needing something to engage two teenage boys out of school for at least the next month. I'm looking forward to your follow-up video!
I am very impressed with your invention, I am a interested in making this system, because this I believe we will have to depend on systems like this, in the future.
wow esto es lo mejor que he visto en mucho tiempo buscando informacion. Muchisimas gracias, porfin podremos tener luz en el rancho. Intentaremos aplicarlo
Wow!! What an incredible creation!! Respect!!
UA-cam algorithm on point! I've been wanting to do exactly this but didn't really have access to a good site until recently.
I was looking to send this to you Joe!
@@yv6eda I was like #50 to watch it somehow.
The efficiency on this will be absolutely terrible I know I have tried it many times please show us the numbers of the wattage it is putting out that way everybody understands completely what is going on truthfully. I applaud you for trying to get power to third world countries at a reasonable price. But if you are not siphoning the water over a culvert the efficiency would be greatly improved.
@@SpencerLAPowerSpencer I agree, low head requires really really high flow but if this could power some lights for as cheap as it is it would be just fine. He could even run multiple in parallel.
@@JoeMalovich in most countries I've sold 2 over the years out of the United States most of them can't get or afford batteries so it has to run Direct to the lights or whatever they want to run . Just curious as to how much power it actually makes given the tremendous head that he has their looks like it's about 10 to 12 feet or more The on-demand power is very minimal but should be able to run a few LED lights. But over time it would charge a battery bank and they could power mini lights and appliances off of it as you know charge controllers and inverter cost money. I'm not trying to knock this guy I think he's doing a great thing to help people that can't afford it.
thats great project!
This is the very exact video I was looking for on UA-cam, thanks for your ingenuity.
Thanks. You see the part 2 as well?
ur a legend man!! glad theres people like you still out here
Brilliant job as always, Daniel! Kudos!
I'm wrestling with zero head hydro power at the moment, but I too have been looking at e-scooter or hoover-board motors for the application, but I might need something even smaller for optimizing for my very small stream... I wish I had head like that... (The village Ram Pump is occupying our only good head and flow)
Thanks.
If you find a smallish salvageable PM motor which is generally accesible and does decent volts per rev please let me know, it's proving a bit of a bottleneck..
If you have low head but high volume, look into a horizontal tub wheel design with a large diameter. The construction of one is detailed in one of the Foxfire books. They carved it from a solid slab of wood, bound with metal hoops like a wagon wheel. A plastic or metal version should be fairly simple to build. With a large diameter and a high volume of water going through, you get a lot of torque which can be geared up to get high RPM.
5Hi there, really do not want to be a small rain parade. My experience with all of this is fairly extensive by this point. Voltage is one of the considerations that tells us RPM. Current draw is the basis for the actual load applied...not just a voltage meter. If you put an actual 50 watt load on the system I believe your RPM would drop to 25% of the reading that you are getting now at possibly 12 to 14 volts which would need to supply a 4 amp output to be 50 watts. It is very deceptive until you completely understand the full process. Hopefully that is not a bummer for you and maybe I am all wet in my summary...just did not see a bulb or motor or something pulling off power other than a meter and that does not count in the real world...
In the process of finding out with the new test version in Berlin. Will post results hopefully by the end of the month.
@@OpenSourceLowTech I second the observation - there is no point in reporting zero load voltage and speculating a current/power availability based on generator specs. Put a simple 10 ohm power resistor across to provide a real world load and then measure the voltage. Make it quick though as (we hope) the resistor to get very hot, very quickly.
Two other observations regarding your very interesting and innovative implementation though.
1) I would worry about maintaining a siphon for any reasonable length of time (days, weeks). Maybe the continuous flow rate will purge any bubbles forming at the top of the siphon so this is not a problem. Hope so.
2) Your observation that the current design with the impeller on top (terrific idea for maintenance etc.) not being dependent on the head as it 'is only dependent on the speed of the water, not the drop height' - I think this is going to be proven wrong. Once you have a load, the weight of the water in the pipe will support the torque on the turbine, meaning the actual power will be directly affected by the head.
Good luck with your project though, I look forward to seeing some real numbers.
@@OpenSourceLowTech you should look into maple sap production and how they run 3/16 lines(as opposed to 5/6) and it actually creates more vacuum in the tubing(sap doesn't just run down the side of the pipe, it seals and pulls vacuum) . I'm wondering If you could see this effect in your device if your down pipe was a smaller diameter that the intake??
@@joshwooten3719 , with that much volume of water at the exit, he could use a much larger impeller and have ten time the torque where he can gear up for more RPM
@@lightrose100 that water means nothing though if there is any air in the tube which could cause cavitation/air pockets. With the impeller at the top, it is completely dependent on liquid vacuum of the water moving through. Ie. You could move the same volume of air through the pipe as water and it would barely spin at all. I'm not sayings that's the case but the sap stuff is at the very least an interesting read.
Hi mate, I just stumbled across your channel by chance and this is exactly what I have been tinkering with in Germany!! Im an Aussie and I've spent a few years playing around with Peltier plates and wind energy. I LOVE THE IDEA!!! Keep it up
Good job guys!
Lowered outlet below waterline, could improve reliability in low water flow situations - then wouldn't drain pipe. Also making additional smaller outlet, to form threeway, and covering bigger outlet with rubber (or plate on hinge and spring) can add enough selfregulation for low flow, without much hassle and cost.
I like this guy
Amazing job, you are an inspiration
truly hope you do the tutorial. It would be ideal for those living off-grid.
just the concept of sharing this knowledge is so beautiful. thank you
Really cool idea. I would like to see it tested under load, even a relatively crude setup like rigging up some light bulbs to it or something, to show that it's not just spinning away and would stop the moment any current is drawn. 5:02 "Will power like half a dozen homes in a developing country ... Italy!" Now that's savage.
@Rens Langendoen Listened to it again, maybe you're right. Besides, Italy wouldn't be the Developing Country - these days that's probably America, given that only the rich have healthcare and many don't have access to clean drinking water. (I'm an American, for context).
@Rens Langendoen Netherlands - relative to you almost everyone's a developing country! I think Italy's doing fairly well though, I had figured this was more a British jab at them - the Brits tend to make jokes like that, and this guy sounded possibly British to me. Though I think the Brits would be more likely to make a joke about some less-well-off portion of their own country in a case like that. Or America, we deserve it!
@@quillmaurer6563 I can go see a doctor tomorrow if I wanted to you just want FREE healthcare paid for by SOMEONE ELSE. America has pretty good drinking water compared to a lot of Europe. We have polluted a lot less due to us being around for less time.
Except California. They are a mess thanks Leftists.
@@rujikin Flint has had undrinkable water for many years now and nothing has been done about it. I will agree that most of the rest of the country is pretty good though, and I'm thankful for that. Even with health insurance I've found seeing a doctor to be far more hassle than it is in many other countries as there is so much bureaucracy involved - the whole system is more concerned about getting paid than taking care of people. This is the experience of myself and of other people I know who have gotten medical care here and in foreign countries. Pretty unanimously they say seeing a doctor is far easier and more convenient - as well as cheaper - in pretty much any other country, even second- and third-world countries. I crashed a scooter in Nicaragua and had the village doctor clean me up, $5 for the whole visit including medication, zero wait time, no hassle, no worries of how it would be paid for, no waivers to sign, no medical history reports, no paperwork. Don't think they ever even asked for any form of ID. They just brought me in and cleaned me up. Granted the place didn't feel super sanitary (open windows and overall a bit dirty), and language barriers were an issue, but still I was very impressed, would take it over an American doctor any day.
@@quillmaurer6563 lol we have great drinking water compared to almost any other country. Classic American talking out of your arse.
Clever man, i'm sending this to someone that does micro hydro generation as this is interesting indeed.
Hi Tailss!! I am going to collaborate for a hydro project here in Italy. Is it possible to reach out to your friend? I might need some tips on how to do it properly. Thank you very much!! Alex
Fantastic job, guys. The turbine looks like the impeller of a centrifugal pump with shroud. So as you pointed out, you only need good flow for this turbine and not much of head.
FINALLY! SOMEONE WHOM DOES SOMETHING I LOVE!
We need people like him to get rid fo the world of polluting and greedy power!!! I am very very very thankful for this video!!!
Hello,
Very good project I love it.
Just one thing you are wrong (or i didn't understand correctly your explanations because i'm not english native). When you say your system doesnt use pressure for its power but more the speed of water. That is not true.
To have power you need P. (Delta V / t) which is a common thermodynamic formula. So pressure and water flow are both important and necessary. And in function of those 2 potentials you will adapt your system (and you did).
Your system works with negative pressures due to water fall. That's why you need to launch it at the beginning. The rotor is runned by this negative pressure with a pulling force.
But with heights higher than 10 metters you gonna reach -1 bar (relative pression) which correspond to vacuum, so a natural limit.
So yeah it becomes more optimised to put the turbine at the bottom of the waterfall with heights > 10 metters.
Another thing, you speak about the cheap price. But you do not include electrical parts and knlowledge to convert this energy to a proper and stable electrical signal.
Anyway still cool !! Did you get 500 watts ? 😁
Wow!!! Well done! You're saving the world!
Great design - quick and easy to manufacture. Thanks.
Great ! Could it be possible to imagine with intermittent energy (solar, wind) to put again the water up 2 meters, so it could deliver stable energy ? How much water could it be necessary to recycle to do so ?
I'd love to see the power results after you have them when you have it under a load! looks promising
In process, hopefully something to broadcast by the end of the month.
Nikola would be proud... Thank you, I love your videos
First time seeing a syphon turbine. Amazing
Sink both sides deeply enough into the water, and then it works year round even if the top of the water freezes.
The pressure would equalize if both ends are in the water. Keep the water moving and it shouldn't freeze.
It is interesting having the driven member at the top. However, it does not matter where the energy is extracted from the flow, because the total amount of energy depends on the volume of water and the distance it falls, no matter where the energy is extracted. Higher voltage means lower loss for transmission of the power but then the higher voltage must be reduced to the voltage that can be used by a particular user. Unless there are fairly high resistive losses in the transmission of the power, which is unlikely over short distances, it would be better to produce the power at a voltage that can be used directly. If the turbine needs to spin fast and only low torque is available then an alternator from a scooter may work well. The rectified output could be used to charge a 12 volt battery. This battery could then be used for 12 volt LED lighting. If 220 volts are needed then modern inverters are energy-efficient and available worldwide.
how does the distance the water falls _after_ the 'driven member' affect anything ? Seems like only the distance above the driven member should matter
This is awesome! This small-scale, upper river type system won't wreck riverine ecosystems, and it's low-tech so that villagers could build and repair. PVC roll pipe would allow much higher drops than what you see here and can go into very rough terrain. Villages could have cell phones, lights, refrigeration, computers, schooling, rechargable scooters and more.
What a treasure of a channel, glad I found it
Use a storage container add a few ram pumps, and a water wheel, battery and multiple generators
Nice concept. Ingnore the haters if this works for you that's what matters.
Excellent . Cheers mate. Sending love and gratitude to you and your family. Many will have their quality of life increase . Many lives will be saved. Many inspired. Our children are the future and they are watching this! Amazing & beautiful.
That was impressive. This looks useful.
Everyone's asking if a second impeller at the output of the tube would increase power. It wouldn't, as each impeller removes momentum from the water flow, and so slows every other impeller as well as reducing the maximum available power in the system.
Having the output water pouring over a water wheel wouldn't have that effect as the water would then be in open air, but the wheel would take up vertical space which you'd get more power from by just having extra pipe.
I'm currently in Berlin working on optimising and load testing the turbine design. Once I'm happy with it I'll be doing a full open source build tutorial, hopefully before summer.
Kannst du mir einen s chicken nach Kroatien? :)
not sure this is completely correct.
after the first stage (first generator), the water is in free run/ free fall.
you may need to adjust the design, but think of the water vortex turbine.
that might work
Is that possible to make perpetual motion water out of that in a way that it will be installed in a huge elevated tank of water, the the passing water on that will be pump back to the same upper tank by couple of ram pumps which basically same water running to the second level tank. Water leak through the ram pumps will be sucked back using air pump system located higher than the main tank?
Please see below systems.
Combinations of all of that will generate continues flow of water and energy?

Is it possible to install eight of these on 25 foot long x 8 foot tall fence post, (as a recharging system), the downspout water is captured into a retention tanks, then with an Archimedean screw, move that water uphill to an organic filter ( sand gravel charcoal ) before splitting into dual feeds for both compost heater( Biomeiler) & Rocket water heater system and Cold Water Tanks?

Definitely cool stuff!
You just have to remember that, in many parts of the world, you have to have legal permission to use waters for most applications (frow aquaculture to hydropower). So you can't just pop you turbine into the next river to generate your own electricity.
Wow, what a guy. Instantly subscribed after your intro. We need more people like you in this world.
Thanks!
I only just realised that the 55 volts I was measuring was from two of the three AC phases, and so the post rectification DC voltage would actually be closer to 90V, which means, other than less line losses, I only have to apply a 3 to 4 amp load to get more than 200 watts output, depending on how much that drops the revs and therefor voltage.
I also know some people currently working on a hack for hoverboard wheel which uses a load braking controller board to short the generation coils and (hopefully) significantly bump up the volts per rev, at the cost of a little efficiency.
OpenSourceLowTech I have a 2kw 70vac low rpm vertical generator that has 3 wires coming out. Is there a budget way to connect it to 2kw home inverter ? How do I do that ?

This system is amazing. I think this will solve my issues by providing power 24/7. I have water on my land here in Florida and this can literally charge up a battery bank, supplement my solar. We have NO wind in Florida so water or solar is king. Solar does nothing after 630pm. This little guy puts out and keeps putting out. I LOVE it. I am assuming that you are priming it to create a vaccum which in turn pulls water from the source , through the turbine and back to source? I need a email for you, I want to send you video of my waterway off the river so you can tell me of I can get this to work. Drop me a line at adnubian@gmail.com please. Check out my videos also , I'm sure I have video of the river up. Great work!!
Good work sir....but instead of 3 phase generator why use a dc generator so you can avoid rectification losses, As your impeller has a good rev range
This really an impressive turbine. We also wants to use it at our fishing pond in Austria. There is no electricity but a lot of water.
which diameter do the pipes have? 100 mm or 150 mm? Is the repeller really a pc fan? The generator is a hoverboard motor, is it AC or DC?
The pipes here are 110mm up to and including the impeller (which is an ATX computer power supply fan), and then immediately after increasing to 125mm. Just because these are standard PVC sizes which seem to work ok.
The hoverboard wheel is putting out three phase AC, which will ultimately be rectified to DC for charging a battery.
@@OpenSourceLowTech That's so cool. You made something and made it from what you had available. Thanks for posting that.
Very useful it help people who live on developing countries like mine....
Wow! That's incredible!
Thanks for all the helpful comments. I'm currently in Berlin working on optimising the design, including ways to maximise the rpms and voltage, so as to be able to have less load for more power overall, and try to hone in on that hundreds of watts figure.
I'll be publishing all the results in a future video soon. Any suggestions and recommendations for ways forward are certainly appreciated.
And if you have any technical questions let me know.
Hey Man, I like this project and live in Berlin, I would like to help you to optimise this project, I have a master in Electronic Industrial Engineering Energymanagement.
Ok cheers, happy for any help I can get. Email me, address is on the opensourcelowtech.org website.
Quality balanced bearings to reduce resistance,
Why couldn't you place generator'(s) in the down flow pipe as well for additional output? Just thinking out loud! Nice work.
Do you know how the dyson vacumm advanced? Vortex within a vortex = exasterbated flow, mite work with kw output too?
I like the idea of the siphon. Nice design. Do you find, with such a small, multi-blade impeller, do you have any problems with clogging due to debris in the water? Also, might your analysis regarding speed vs. torque demands differ when the generator is under load?
Seems the turbine is sitting in a section of pipe where there is little new water. You could always add a big mesh filter at the inlet pipe to minimise any debris entering
Brilliant stuff we need people like you
just finished to build one, can't wait to try! thanks!!!
Nice one, let me know the outcomes and if you have any questions. Personal email's on the website.
I'm about to build one too but for a different purpose. my goal is to encourage allot of farmers to stop pumping with gas powered pumps to pump from a river that's already flowing.
I would be curious to see you put a real load on it,
i'd be surprised if it could handle 5 amps.
It's charging ability is great.
I would like to see it running with a load taking 10 A; wonder if de generator can deliver it at 50 V. The tension will probably drop to 25 V if not regulated. And I wonder what the torque in that case will do with the plastic turbine.
Keep up the good work.
With 10A it will drop way lower than that
that was the invention i was expecting for. thank you
I am looking forward to see the step by steps of construction of it like you mentioned in one of you videos it would make the world a difference even in my family!!!thank you
i hope that the tutorial will come up soon i would like to learn from it and share it to the the remote area in the philippines where people dont have basic electricity this could be a big help.
Yeah please do. I'll be putting the tutorial together in the coming months, once the design is sufficiently optimised and tested.
thank you sir this could be a big help for those people in need once the design is finished ill be more than happy to do it and hoping i can get help from the government once i made some proposals thank you again sir and Godbless you!
Have a merry Christmas and happy new year sir!
You too.
@@OpenSourceLowTech Hi there. In the video that you show how the turbine is turning the motor through the pvc pipe at the channel, can you please tell me what kind of motor you used there. Thanks Leon
SOME PEOPLE HAVE ACTUALLY GAVE A THUMBS DOWN TO THIS VIDEO? WOW WHAT IS WRONG WITH THEM.GREAT VIDEO
For UA-cam this has all been incredibly supportive.
that is crazy! thanks for sharing
I like your design and priming method. Subscribed.
Simple and effective. Have you considered adding more turbines to your shaft? That will provide more power which will be important as load increases.
It wouldn't work
@@johncheetham7789 Just a laywoman's pondering...
Wouldn't more turbines increase torque? That would help maintain speed when load increases.
Am I way off base?
@@r-platt the second would have to run faster and so on. Having another turbine at the same speed in the same pipe wouldn't increase efficiency. It's an easy mistake to make. I wasn't trying to put you down in anyway.
@@johncheetham7789 Thank you! This is an opportunity for me to learn. I take no offense at anything you say.
Reading back on it, I had the idea backward. Increasing the surface area (e.g. adding another turbine to the drive shaft) would slow the water rate and reduce power. But the increased surface area would mean more consistent power with increased loads on the generator. Thing is you would probably need fins attached inside the pipe between the turbines - like a jet engine. This would straighten out the water flow from the first turbine making the 2nd more effective.
What about decreasing the pipe diameter just around the turbine? That would increase water speed and pressure through that segment.
Feel free to keep calling me wrong. I'm no expert. I just get wild ideas now and then.
Needs a 2nd turbine in that water column.
congratulation my fried... muy buena idea lo implementaremos en mi comunidad.
Absolutely fantastic !
