- In this video I make modifications to the design in order to fit a induction motor used as a generator. I then go over to johns to get the capacitance right and then back to the wheel to get everything up and running.
My 5yr old son and I watch all your videos… then we go outside, build something… He even says ‘well pleased with that’ when we are done… 😂❤
Being an EE retired since 2011 I am impressed with your grasp of the mechanical and electrical specifications and skills needed to correctly design and build a one off generating system to a specified output. Great Job. Ray Stormont
Maybe you can answer me then. It appears to me that there is plenty of force from the water to turn a different gear ratio for a higher ratio towards the motor. Could this be done to change the 1500-1600 produced, into 1800ish? What fails in this scenario? I'm no sparky, I play with bricks, blocks, and stones!
I am also a retired EE about 10 years ago.
I don't believe a gearbox could produce more output, as Kris has actually already shown by using more water. Because the resistance is too great and the wheel slows down so much that the water fills the buckets too quickly. The only thing you could do is make the buckets wider. But that means you're actually starting from scratch again.
@@slyknowledged The limitations most probably are in the water wheel and that cannot be changed by gearing. As Chris shows the buckets are filling up and peaking at 1500-1600 W. Changing the rpm with other gear ratios should not make much of a difference there, just risk increasing the splashing and losses.
@@slyknowledged or give it a higher resistive load with more capacitor
Excelant points pre-loading the buckets would allow for slightly more water and cut down on splashing and could be easily returned to original if benifits were not proved as buckets are not changed just more completly filled.@@henkkalter3892
Ive been planning my future dream home in a journal at the moment and was looking for a bunch of different ways to sustaibably power my home so I can live off the land, and this little series is PERFECT! it's inspiring and given me the desire for hydroponics on my property❤️❤️
Thanks for explaining that this was fed from a leet, which was a minor diversion from a much larger river. That made a lot of sense and added good context to the project.
I would love to have access to water like that. You’ve done a top notch job on this system.
But would you be OK with the rain that's required for that water?
I’m in Oregon. I live with the rain. It’s not like where Kris lives though. 😊
@@flowerstoneI think rainfall levels in Oregon are higher than in West Wales.
@@MaritimeFox I just don’t have a creek close by.
@@MaritimeFox West Wales? I thought this was Lake District.
I really like how you can't stop smiling when you look at your creation. You are, and should be, very proud of what you've imagined, designed, and built.
Awesome work.
Would be possible to add Archimedes' screw for that spillway? for extra generation ?
We are all gradually going back to how our ancestors lived.. and that’s a good thing because there was no impact on the earth and people were happy just to be housed and warm xx amazing job you are so very clever xx
HI :) Good job !!! :) Nice hydroelectric !!! :) Beautiful !!!!!!!!!!! :)
Regards - Paul P.
As a fabricator I am really impressed. As an insaller I am blown away. How many trips up and down the ladder an in and out of the river. I hope you made great money and I thank you so much for sharing your knowledge. This video is a master class in the challenges of invention. Congrats!!
guess he doesn't need to remember leg day while on this job
Do you wear safety glasses?
@@richspillman4191 Wtf does that have to do with it?
@@unhippy1 One million eyes are lost per year, always wear safety glasses, don't take shortcuts when it comes to safety THAT's wtf it has to do with it. Unless you think it's cool to look like a pirate.
@@richspillman4191 I mean... it does look cool to be a pirate but it's also good to avoid eye injuries anyway
you can still wear an eyepatch without bodily harm anyway
Was literally just watching an older video thinking to myself "Man I hope Kris uploads today." Thanks for the great content over all these years Kris, and I hope for many more! Merry Christmas to you and yours.
Totally agree.
for me whenever it comes to Kris upload schedule I stop watching like 4 and 5 months i come back where I life at and I have so many videos to watch 😊
Very impressed Kris. Watched this series from the beginning, trials, and Tribulations; and your problem-solving. Your client also deserves credit for working with you and having the faith to persevere.
You’re a genius mate. I like the fact my son is also called Kris, he’s a little brain box too!
I'm in absolute awe of everything you have achieved but this my friend, is an absolute masterpiece!
I absolutely love this project and I'm so jealous of the owner. I invested in a load of solar panels and batteries this year which will save me a fortune over the course of the year even though they are pretty useless this time of year - I have over 9KW peak but they produce next to nothing in this grimy-greyness.
To supplement them, I've been watching your wind turbine videos, and I'm experimenting with the motors from an old "hover board" but really I'd much rather have a water wheel for the consistency and sheer power you can get from one. Overall, the peak values that solar can produce do not compare to having something generating 24x7.
The wheel you've built is the best I've seen on TH-cam by far.
Exactly this for me. When i was looking at a house ti buy i was wanting to have water like this. But where we are we get lots of wind so im probably gonna go that route for power gen to augment the solar. Cuzz i dont wana rely on sunnt days though we tend to get a lot of those around here too
A 2.2Kw asynchronous motor can provide 2.6Kw used as a generator. (5.87A*3*230V*cos fi 0.64= 2592W) In the old days here in Denmark we made wind turbines with asynchronous motors as generators. When the speed of the motor reached above synchronous rpm, a contactor connected directly to the mains. In the event of a mains failure, the motor loses magnetisation and runs freely. Nicely done project. Comment from a Danish electrical technician. 👍
The way I saw micro hydro turbines do their shutoff/deflector setups is they use a weighted flap retained by an electromagnet. When there is an emergency the power to the magnet gets cut and the deflector plate drops in place. Similar could be done here. No moving parts for the actuaction itself, as long as the eights are sized propperly. Anyway amazing job, the survey was really close aswell! Enjoyed watching this series.
You can use water for power without destroying the enviroment, thanks for showing us that.
Great video for a Friday. Amazing design, engineering, and fabrication. A great achievement!
Epic. You know when you can understand how to harness natural energy that you do not need anyone to tell you how to live........ there are a few who know, there are less who understand.
I'm well pleased to find your videos :) Amazing job
I enjoy these hands-on videos from Kris, great stuff!
Love the safety squints at the start. Would some kind of cowl/hood around the area the flow meets the wheel to catch the splashing help keep more water bearing down on the wheel?
Look at the size of the generator,,,,sweeet! Now I watch rest of video
Great success, congratulations and greetings from Finland !
Congrats Kris - this is and incredible project. I am truly amazed at your skills and I love to see the obvious joy on your face as you see this working. Thanks for sharing this with us!
I'm impressed by your ability to teach yourself advanced skills. Then to design and build things is divergent as your shop with its wonderful roof your own wind power your own barn your home. Your credit to people who focus on learning and delivering May you have a wonderful Christmas
He will be welding blind if he keeps welding with no hood or safety glasses.
He DID utilise the safety-squint.
It’s always the fine tuning that the tricky part. Never give up.
Thank you for your work, I enjoy your video's, be safe
Great job will last for years ..theres lots of haters and negitive people ..if we listened to them we would never move forward ..keep educating son ..your a positive force ..mike Scotland
Kris you are an absolute genius...great work great learning great prototype for future projects..keep up the excellent videos I'm enjoy your content your special camper. ignore the haters
You got it working well now. For those saying that 1-1,5kW is not much, when the system is able to generate 20kWh a day during winter time this actually is enough to run a 7-8kW heat pump for most of the time entirely from water power alone. and it will do it for 24/7 during winter time when heating is needed but Solar doesn't do much.
I use a 7kW heat pump, and with an outside temperature of 0°C it uses 800w on average to keep my house warm, it's just when heating up indoor when it uses more power for a couple of hours.
So you will heat your house without importing from the grid, which is what you mostly will do when using solar.
Functionality and aesthetics ... a build to be proud of for sure!
And it's a thing of beauty as well as purpose, and has a wonderful sound. Brilliant, really enjoyed seeing this fantastic project to the finish, great to see you working through the problems to this wonderful piece pf engineering that will be turning for many years ahead. I think you need a plate on it with the date of construction and your name for future generations to see.
From an EE point of view I have found this series fascinating. I have to add that I am far from an expert in generator systems, so I have been learning along with you.
As a mechanical tech i can say BRAVO !, its a hell of alot of work and keep in mind that this is a functionnal prototype, it was a high risk of complications project, absolutly beautiful !
Hi Kris. What a fantastic looking hydro wheel system 😊 It’s absolutely brilliant that you never give up until you’re 100% satisfied 👍🏻 Hopefully the customers will be satisfied with your design and work you’ve put in and you’ll get more commission out of it 👍🏻 Well done 👏🏻
Here's a thought: since the water picks up speed down the ramp it tends to load into the bucket at a high velocity. I wonder if it's possible to SLOW the water just before it falls into the wheel buckets (to reduce splash)? A mini dam who's 6 inch depth would absorb some water turbulence prior to dumping down into the bucket (or even a couple 1/4" bumps near the end of the ramp). Especially since your power is from water weight and not water velocity. Just a thought! Great project.
Some great points there but water inertia increases derived power
The splashes are caused by the buckets, In my system, i bring the water from the other side of the wheel bu I still have some 20% losses
Hi Kris, I'm no engineer. I can't do the math let alone remember all the formulae. I was blessed to be able to work as a technician (the hands on guy or grunt) with many many engineers from all over the world at GM, so I got a chance to converse with them about everything from the theory of relativity to lunch for nearly 40yrs. I'd like to try and add my hairbrained idea if you wouldn't mind. My understanding of how an inside component of an automobile transmission torque converter; the "stator" works is: A row of small stationary "foils" attached to the casing of an axial-flow turbine, positioned between the rotors, that redirect the splashed fluid back into the turbine to add torque. I am referring to the splashing of water that appears to exit over the bucket and freefall through the air offering no further energy after it has splashed. By redirecting the splash inside the automatic transmission torque converter the torque is multiplied so greatly that I don't believe there is an automatic transmission in the world that doesn't incorporate it. My own vision was/ is a shield that is designed/ sized to redirect the splash back into the buckets, sort of the way the housing fits around a turbo charger. Fun to watch you and thank you for endeavoring to persevere seeking solutions to all the issues. Merry Christmas to you Kris. ben/ michigan
Inspirational serie. Peak problem solving skill.
The water chute to the wheel could be enclosed ,slightly above the water to funnel the water to the buckets more efficiently (less splashing).
Yes that should work, but that enclosed funnel needs a hinged "roof" so it can get pushed up if there are any larger objects in the water which doesn't fit into the buckets, for example sticks or an empty bottle or maybe even a soccer ball.
If the enclosure is completely fixed such objects would jam between the enclosure and the wheel. With a hinged top plate, it can swing up and let the objects pass through.
the screens Kris uses on is micro projects could improve water flow but then thy need to empty quickly How could that work . Secody exist hols parps like in life boat's
Been looking forward to this.
Bit surprised to see you welding without your visor on, but glad to see the good old safety squint in use.
Loved the stack of crates of carling in your friend's otherwise super high tech workshop :-)😂
What an interesting game your in, your doing what I dreamed of, fantastic
I would actually say there is a beneficial environmental impact from the added waterway. More riparian, more habitat for aquatics, more room for floods to disperse. If you don't have beavers, having humans rediverting water intelligently is the next best thing. Not to mention that you are using it to produce power so you aren't leaching off the carbon fueled power grid as much.
Also, I really enjoy your content. The knowledge you've aquired and skills you've built are quite impressive. And while these comments from impressed viewers could easily overinflate your ego, you don't seem to let it. Good on ya, mate.
Brilliant job, glad you got the issue sorted out and the plan worked out ok.
Great job Kris, glad you were able to find a work around. It looks stunning in its setting. Shame about the mis info on the first genny. Onwards and upwards now and better armed. Well done. Stay well.
I would love this in my garden! 😍
Well Done Chris, you did it!!
Outstanding job Kris, it’s a great feeling when you’re proud of what you’ve achieved.
Really pleased you got it sorted. I'd love to see the temps of the new motor at peak flow in the next video! 🔥
A great job Kris. You have come a long way!
With the efficiency of the motor/generator your calculations are spot on. 1.7KW at 86% is only 1.4KW. So really you are getting more power than estimated. (If my Brain is thinking about it correctly that is... :-) Excellent vid and glad that it worked out.
Isn't it the most awesome feeling to take an idea and make it manifest? It's why I adore making things. Especially things that take you and stretch you a bit beyond what you've done before. No other feeling like it.
I love to see someone that understands the whole process and can actually build a system from scratch. As someone that has been heating a 4000 sq ft home for 21 years using WVO that costs me zero I really love the quality of the hydro system posted. Keep rocking. Philip from the emerald isle.
Excellent job, congratulations ! Great video too.
yay great gift you have produced for the end of the year as your Christmans control of water wheel energy to start of the New Year with beautiful sense of power and light. happy holidays aloha
Fantastic job, Kris, and a very engaging video as always. I doubt you'll see this comment as there are so many, but my only criticism of your system is your use of an AC-to-DC power supply to power a low-voltage contactor for the load dump. I (an EE) would've used a contactor with a coil that could be powered directly from the mains, eliminating the AC-to-DC power supply and increasing the reliability. Sorry if I've misunderstood your system but I think that's how it works.
Congratulations on a major milestone Kris!
How about a flow divider of some sort, controlled by your sensors, to maintain the wheel at the necessary speed/flow/load by directing more or less to the wheel. Think boat rudder and autopilot actuator.
I think the splashing could be attributed to the "Pelton Effect" happening in the bucket, especially if the wheel is being electrically braked but the flow volume is high. There will be that sweet spot where the wheel speed and the flow match. Crack on Mate. Ex Heli Engineer, 30 years in Film. Enjoying following the progress. Thank you
I gotta stop commenting before I watch the whole video, innit? Lol.
These should be put all across the land.
_MAGNIFICENT!_
That slow flow-rate sounds like a well balanced locomotive chuffing along a flat track.
That's really cool well done!
Perhaps to improve the laminar flow of the water, perhaps fill the trough with pvc pipes- if it works with straws, I'm assuming it could work with pipes- it may help with the splashing- that or fins at the end, if it works on propellers, I could see it working with water- who knows, could get an extra few watts out of the system
Congratulations! I've been thinking about the amount of splashing you have. It might be useful in future designs to extend the bottom of the buckets upward/outward a bit because you loose most water over that edge. Another point of interest might be the shoot. As there is a bend quite close to the end, you might be able to create some less turbulent flow by putting some parallel thin metal slats in the section between the bend and the end, so as to guide the flow to become parallel (or laminar).
I hope your next video will be out soon and show us the progress you made on the barn. I guess you may have fitted a roof on top of it by now.
Brilliant hydroelectric work. Finding the proper motor generator for this job, means you're set for building next projects. Your patience with the armchair ecolo ignoramuses is phenomenal.
Thanks for sharing this smashing project. Very interesting indeed. BTW, haters will hate, fact resistant haters don't care about the environment more than using it to shame people with catchy statements. This project will give environment friendly power for years to come.
Love this video series, brilliant work and so jealous of this facility! Cannot believe the people complaining about creating 100% green power by temporarily redirecting some water.... you'd think they'd prefer your client used a diesel generator maybe! 😂
Great work Kris. Dedication to the job and pride in your workmanship. Often a rarity these days. You can be rightly pleased with yourself especially in the knowledge you achieved it even in the face of adversity from those who don't care as much as you do.
Really impressed with what you do. I have just discovered your channel and am enjoying it immensely and learning a lot in the process. Thanks
Well done, young fella. Nice job.
Excellent work and perseverance Kris! Can't wait to see more hydro projects you do
Well done on getting those figures and getting in line with your model expectations. I imagine with all the variables that isn't easy to do on a first project like this.
ive watched them all . just one to come . its clear your a happy man with that .i also loved your home wind mill . Thank you both you and the wife and merry Christmas to you both
Fantastic job. I want 4 of these.!! Keep at it 🦾🧬
Great video!! Fantastic to watch an honest appraisal & in a way public can understand. Thanks heaps for calling them out. Cheers from Australia
Kris you never fail to amaze me, glad you managed to get the water mill working to everyone's satisfaction. Merry Christmas and a happy new year.
excellent job Kris! Your tenacity anf knowledge saw you through and the end result is fantastic. Also the sound the wheel makes at steady state is dreamy :D
Well done! The young Oliver Evans would've been impressed (said the yank).
I would like to have such a river.
Great job!
What an epic achievement! Thanks so much for taking us along with you and for clearly sharing your journey.
Your videos are so therapeutic to watch. Both your craftsmanship and presenting style. This series has been my favourite i love watching water flow
I think diversionary hydro will be an important component in electricity generation globally going forward, its really wonderful to see just how well it can scale down, its probably the only consistent source that can do so safely, and with minimal impact on ecosystems.
👌lovely workmanship .
You have created a beautiful work of practical art. You have also demonstrated the sheer amount of intricate work and materials and planning needed for an open falling water system. It now seems obvious to me why those with the will to take on hydro usually choose a pressurized system with pelton wheels. It seems so much less intricate with modern materials. Perhaps at some point you could create a video comparing the scope of each option?
Much respect to you. Thank you for documenting all this, have enjoyed all of the episodes.
Love the stack of Carling crates in johns workshop 😂 good lad
U are great Kris. Very nice and clean project man. Congrats!
Thank you very much Kris, I've learned so much watching your work. Question please, can you discuss with us, the maintains requirements that goes with have a system like this. I love your work, and how your mind thinks. Thank you for sharing all you do.
Kris, I’m absolutely delighted for you in your success and impressed by your array of skills. Learning loads from you, keep up the good work.
Its amazing how much more complicated hydro is compared to installing a solar array.
Inspiring. No grid down with you lot. I'm moving next door.... when the appcolapse hits. Good on yer.
Congratulations Kris, an ambitious project very well executed, when I started watching your channel I thought what a talented carpenter/cabinet maker, turns out you are also quiet the accomplished engineer.
Excellent work 🎉
Now you need a ≈20-30KW hour Batterie and you are safe with your own energy. 24x1,2KW = 28,8kWh, in a house you need about 8-20kWh per Day. so it is possible :). Very Very Nice Build and you are so lucky with your own river!
Like the harmony and tone of the water going over at 800 watts and up. It is a very old familiar work sound. Used for many businesses, get flour from wheat kernels, grinding pulp for papermaking, processing natural fibers for cloth, hammering iron.
Just wish our kitchen cooking ovens were better efficient. Think of 1500 watts for a stove induction cooktop burner, mini convection toasters, air fryers, and add 1000 watts needed when fridge or freezor compressors start.
But at 1200 watts can run room lights or ceiling fans, charge tablets, laptops, phones, or have on a large computer for video games, video editing.
For Chinese purchase, think it needs to be said, have to learn...what item really costs and so can determine true quality. I have bought things overseas from Japan and China off of ebay and for higher priced items happy with craftmanship. Thanks for sharing experience as clean energy is already squirelly enough.
Very impressive as always
I hope you came out with few quid profit after all the messing the Chinese motor caused!
Absolutely love this beautiful job. U continue to amaze me with your skills - can’t wait to see you back on the barn- hope you get the shingles on this winter- the rest can wait until spring- I know financially you wanted to wrap up the water wheel project.
CONGRATULATIONS EXCELLENT work 📣
Love this! Proper motor and proper build and lets not forget.. MADE IN UK!. I hope this goes viral everywhere so these chinese arent selling those crap motors anymore.
I would be proud of your work too. It is a vey well thought out system. It was a shame the Chinese piece didn't work out but it shows how you excel in diversity and overcome obstacles. I Look forward to more of the great content you share with us. Cheers
Kris, fantastic, just thinking back to the days of you building the roundhouse. I come to your site to go off grid myself, it takes to me another place. I understand that there will all ways be faceless warriors who know best, I just wish they would recognise the story you have told over the last number of years, the huge following you have. Congratulations Kris, Merry Christmas to you, the cat and Dot.🎉
Well done ! Very pleasing !
Wow, Great work! I've learned a lot. Thank you very much!
