Hydroelectric custom stainless steel intake Part 2 Installation
Вставка
- Опубліковано 18 чер 2020
- In this video i install the intake i made from scratch. it was a very wet and rainy day that made fiming very difficult.
it dose seem to be working great. time will tell if i need to make any changes but i will need to monitor it for a while first.
Even liked the bucket plunks sort of like Japanese water bamboo sounds went with the job. May all your engineering be as super quality thanks.
I got so excited that you posted a second video that I forgot to compliment you on your TIG welding on the first one. A perfectly acceptable job for a new welder.
And your hydro set up is very good also.
You get a well done sir. Keep up the great work 👍
Im not sure what quarantine is doing to my brain, but watching the developments of a tiny dam in the english countryside is the most interesting thing I've been watching for the last 12 weeks
lol so true ..
Kris, you never fail to impress. It was really cool to see your hydro set-up starting up after watching you build all that a while back 👍🍻
I have watched several of your videos now. I’m 60 years old and not easily impressed, but wow all the different things you try and master! Your positive attitude is refreshing and your patience! Keep those videos coming!
Looking really good Kris, nice to see it self cleared most of the heavy leaf matter. And the extra head giving just a smidgen more power is the icing. Well done and kitty looked like she was watching a fish or something have a swim in that little bit of water. I could see you were excited to get that in and testing, lovely to see your video's, thanks so much to you.
I have seen many videos shot in the rain. Yours is much better than most, you did a great job sheltering your camera from the rain while maintaining a good view of your work.
Super! Excess power from such small flow, I call that a success... the flow over your Coanda accelerator appears very smooth and laminar and you seem to be getting plenty of flow through the screen despite the fine debris - looking forward to the next update on how the screen is holding up. Fingers crossed it stays OK, because fitting a Coanda screen would add considerably to the complexity and cost - and you don't want that!
I vounteer maintaining a microhydro (18kW) in South Wales, our screen gets blocked even with a coanda screen...we go up once a week and clear it, sometimes needs more in Autumn. It's surprising how much water gets into the top tank even if the screen is well covered in leaves.
Looking good from the video though...well done.
Hi Chris, that sounds like a nice job to do, i would love to get to mess about with an 18kw system. :) Thanks for the comment.
@@KrisHarbour I'll dig out some info and email it over if you are interested - it's only been running 3 years so far but seems to be doing well so far.
Chris, could you give us a video tour of it? :-)
@@MarkRose1337 I suppose I could do...I'll see whether the owners have an issue with that - don't see why not.
@@TheTaff224 This would be good to see :)
Shower head caps are great for covering over cameras in the rain. Always take a couple with me for that reason
You a legend mate 👍🏻
Shaun Curr cheers :-)
That's a nice tip there!
Mme. Hyraelle thanks I use them when I do bit photography:-)

I love watching other people work! There is just some serenity over it. Good job there, Kris.
Love watching you work Kris, we can all live vicariously through you.
You have a tremendous amount of ingenuity tenacity!
I really don't understand why people would click on the 'dislike' button. This is free content you are watching, someone has gone through the trouble of sharing it with us and whilst it is not 100% perfect, I suggest, give it a go and then comment with how Kris could have improved.
I look forward to learning from you and with you Kris.
Keep it going and GOD BLESS,
Hi Kris!
Not sure if you remember me but we used to go to school together many years ago. My husband and I love watching your videos, living the sustainable dream. Hope your keeping well. Kx
Well done Kris, ingenuity and perseverance wins the day. Look after the Dewalt gear, my own experience is that it doesn`t like the wet. Keep up the great videos please.
Love the videos. My girlfriends family live in dense forest in Laos. Amazing to see how they diversify and work the land. Large snakes, wild cats etc are the norm, but you learn and learn quick !
You have some of the coolest projects, been following since halfway through the round house. Can't believe how far you've come. Love all your videos and your lovely banter towards haters! Keep up the good work, Kris! Thanks for bringing us along!
Thanks for another interesting video, Kris. It's amazing what hard work and ingenuity can achieve. Strength to your elbow.
Use a small bristled brush that rotates on the screen from the power of the water. 👍🏻
Great work... just a thought... would there be any benefit from a sort of floating boom that runs from the edge of the overflow out across the pond.. to prevent the crud actually getting to the intake? In low flow situations all the leaves would end up in the corner near the overflow then get washed away when the level increased. . In fact it could be a fixed piece of timber across from the overflow to the other side of the pond that stops the floating leaves and diverts them to the overflow while the clean water flows under the timber leaf free to the intake screen
Nice sturdy shovel. Envious of your weather. It's going to be 26.6 C today here on Long Island NY USA
Like your water inlet screen- saw another style that rotated- yours seems so simple and will work really well.
Nicely done Kris. Can't imagine it did not get good test with the rain that we just had.
Great work Kris. Good to see your progress. I love the off grid videos. Hopefully you'll have an update on your wind turbine soon. Looks like you've also created a lovely wildlife area at the new intake. I'd be sticking a bench in to sit on up there to enjoy a few beers
Great video. I'm glad your hard work and effort has fruited results. Really enjoyed watching
why don't you bend a pool noodle in u shape and attach so that it floats in front of inlet to prevent leaves from even entering (like they do on some dams)? I can't remember what they call it but its normally logs attached together with chains that float in front of the inlet. ok, hope that helps. you don't need to worry so much about how to clear if it never gets onto the mesh in the first place ..love your mind.. it is very calming to watch you work! you have a great product thanks for sharing your inventing process with us.
Log boom
That sounds like a good idea to me.
It is called a log boom.
I think silt is the main issue here (looking at the video, leaves just seem to wash away by the current), don't think the boom would stop that. Then again i'm not an expert in such things
Morning kris just watched the crabs video...amazing.u r such a clever guy...the things u do.imagine what the world would be if most guys were like u...watching u from cyprus meditteranean
Kris I really think you are on to something here, especially your wind turbine - well done!
I found your channel last week and have watch all of the shop build to date. You have really inspired me to look at hydro electric production. You have great ideas and very eager to turn your energy into action. I do have a suggestion for your screen trash buildup. Take a beam about 50mm thick from between your overflow and your intake spillways to about 2 feet on the left side forming a triangle. Notch the beam so the bottom is 25 mm below the surface of the intake spillway. It will stop the debris from flowing over your intake spillway and when enough overflow is running it will wash it out the overflow spillway.
Kris I've been watching your channel. for a while now and your garage ,house,shower room,bath room your really doing something only a few would be brave enough to do my work and on top of all that I think your doing a really top notch job.I get a lot out of your videos I'm now just getting to solar power and now your doing Hydro Turbine,so I see that not only do you have to work hard but really smart took congrats on a he'll of a job.
Thank you :)
I actually enjoyed the rain in the background. Brilliant video. I wish I was this able.
Great work you make it seem so simple I do see the hard work that goes into it though beautiful!!!
Great Job. Exciting to see how the system improves over time.
On your question for suggestions for cleaning your screen. You could put a stepper motor at the top or bottom with a squeegee (like for windows). Small arduino programme to do a few strokes every hour up and back down and it would wipe the top of the screen. If you put the squeegee at the bottom then it would clear debris, but it would also create a slightly raised lip at the bottom diverting more water into the screen :-)
Great work Kris, enjoy that Welsh Summer.
Wow very pleasing. Such a great job you did on this.
I love watching your vids i hope one day to build a cob house and all your bits you do will come in handy for then. Hope you do alot more vids in the future 😊
This video is one of the best ever. Congrats Kris!
Looks great, however me personally would want to catch all the water through the manifold then have it run over. maybe remove the screen go wild at the intake and add in one or two clean outs further down the line. or less finer at the intake and again clean outs further down. i use to design and weld custom stainless parts for building industry, Your definitely on the right track. Nice work. You have a great mind. Thank You.
To use all the water available all the time would mean the turbine would have to be able to run at all those flows. that would mean making a turbine work from 50w up to about 2k you cant do that efficiently there is a power curve to a hydro electric system and if you run more water than is designed the efficiency drops off to the point that it adds no additional power due to losses. so if you want to run massive flows you have to have massive parts. then there is massive loss at the low end and it wont run well at lower flows. The turbine makers job is to size the turbine to work at peak performance at average flows. This way you get the most out of the system over the course of a year rather than just getting a big spike of power while its chucking it down with rain. My system and the intake are designed around my average flows around 3lps but can run up to 6lps anything more than that just creates to much friction to be worthwhile for the sort period of time that amount of water will be available so the extra water is used to clear the screen and it is a great use of that water as having the screen clear results in more energy being available than just using more water because the turbine will run for more hours in the year due to less blockages.
Kris Harbour Natural Building Completely understand the theory. How about Twin hydro turbines? Just split the line ( feed ). However another plan for leaves, etc You definitely have the gears in my mind moving on a way to use all the water. 👍
Beautiful job Kris. That intake should last forever. If 6-ish hours of running resulted in 3 small leaves being stuck on the screen, then clearing them off by hand once a day or so is probably good enough. The large opening is more than enough to run the hydro, even if 1/3 of it is blocked for a few hours.
hold up, two videos back to back! love it
Good job Kris! I hope your plans for designing the intake and selling them comes through for you!
Hi Kris, very nice job. Last week we had a lot of rain, my stream is full of water. My turbine give me around 650/700W. it will decrease a lot with the summer. you should add a large cap at the bottom of the intake, to be able to evacuate very fine sludge which will accumulate in the bottom.
Hi Kris, I'd suggest to use rivet nuts to mount the mesh in case you'd continue to use it. But the easiest way to clear debris, as MrHydrohead found out couple years ago, is to use the coanda screen. Wish you all the best and I'm looking forward to many more hydro and workshop videos :)
Two videos in a day. Brilliant.
Don’t understand the technical stuff but I know you’re brilliant :)
Getting more and more like modern infrastructure, good work.
Thanks for this, I’ve been waiting to see how this would turn out. Good work!
Top quality job Kris - going to have a look at my proposed stream intake area again now !! I can come up with a plan now...
Jack of none, master of all
Simple and to the point.
An (DC)electric roll brush with a timer ⏲️.
Hi Kris, Most mesh has a smooth and rough direction, you can tell with your hand, give it a try. I could be the wrong way around.
Very nice build, well done.
Not often I rush to a video, but this was inexcusable not to!
Excellent work Kris... up to your usual standards of innovation and design
My garden pond filter has a "bow screen filter" (in german "bogensiebfilter") to separate dirt from the water. Works for 8 years now. It does not clog. Size is similar to your mesh.
P.s. all the best with that project. Always a great watch chief🙏
The sediment buildup could most likely be dealt with by changing the top plate. The curvature on it is causing the flow to skip the top of the mesh. A plate that's flush would likely allow the water flow to do a much better job.
Wow! Hydro, solar, metal, wood, glass- is there anything you can't do, except maybe hair cutting? Lol. Impressive!
Im quite good at cutting hair :) just dont do it much to myself.
Okay. I stand corrected. There is nothing you can't do! You're the best. Thanks for the great videos!!
Notice that nothing sticks toward the bottom?
It seems the faster water towards the top is holding the debris in place because of the bernoulli principle. It looks like it slows toward the bottom because of the slight edge created by the attachment strip. Maybe try a small spoiler at the bottom to slow the flow down upstream. I would replace the lower attachment strip with a wider strip that angled back up (closet to level). The other option might be to change the angle of the whole intake, but that might be more difficult. Excellent project. Your hydro setup is very impressive.
how about rotating the screen 45 degrees, diamond rather than checkerboard.
Could you explain why that would make a difference for the idiots like me
@@lord123j You're no idiot, for asking a question. Quite the reverse. It'd create different wave dynamics on the surface, and maybe a beneficial effect wrt to litter shedding. Cheap experiment that wouldn't require further out lay too.
Thank you very much. It's something I've been looking for a lot.....👌👌🏆🏆
The ratchet moving invisibly to your hand at 1 min 50 seconds is impressive 😉
It looks like the only reason it's not clearing is because the screen is sagging a little. It you put a few thin supports under it to prop it up (in line with the water flow), the water will be in continuous contact with the screen and keep it clear. Or, you could back the existing screen up with with a stiffer piece of course screening underneath.
Kris, when you had your loose sleeve next to that spinning turbine it had me feelin really uncomfortable!
Please be careful.
You could add a semi circular strip of metal about 100mm wide and long enough to fix to the upper side of the sleeper 50mm above water and 50mm below water level. that would stop the majority of debris getting onto the screen but not stopping the water getting to it.
You need the screen/mesh to arch ever so slightly upwards, so that the water actually flow along the surface of it. As it is now, the water is actually skipping a big part of the screen. Some steel wire like construction under the screen, with an arch on it, to keep the mesh from bulging down, to keep it at an small small upwards arch. That will force the (excess) water to flow in contact with the whole mesh and not only a part of it.
Hi Kris, looking good mate, I think maybe the sediment problem could be resolved by reducing the screens to just 1 layer as the sediment is probably stuck between the screens. 👍
Yeah i am thinking that to. just one layer is quite flimsy. i will do some more testing and observing and maybe change it if necessary
@@KrisHarbour maybe put a barbeque grill underneath to support it?
Excellent innovation 👍👏
I used to love to work in the rain..but it doesn't rain much where I'm from...southern California
Get a little white hardhat for that kitty, a very well time inspection visit!
I wish I had enough money to live that cozy, and like a Hobbit.
A thing of beauty great job my friend ❤️👌
Just a thought about that grime building up on the screen, I believe that other hydro power video from a few years back also had that problem .. and if i remember correctly it has something to do with that 'bump' where the water flows over (and creates a bit of an air gap underneath) and the angle of the screen...
I think the debris is just from the volume/rate passing through. I’m guessing it’s not exactly flat and possibly sags slightly so the flow was missing the screen after the lip with the flow rate.
Hope it’s still working well. Great to see home made power systems and people’s ingenuity. 👍🏼
Hope the hot water cistern was full as you must have needed a hot bath by the time you finished playing in the stream 👏🏻👏🏻
Couldn’t you make a paddle wheel that continuously sweeps off the screen?
That sounds like a good idea! There’s so many useful tips and ideas in this comment section!
nice natural stream ruined by plastic pipes.. welldone
Awesome job!! Any stuff that sticks to the screen could probably be brushed off with a toothbrush. It's too bad all screens are made out of nylon now. The screens for our house are the original (circa 1959) metal screen. I like those better.
Ok. So I have watched you build this whole hydro system, starting with building the weir, and I am sorry. I feel immediately compelled to tell you. I am so attracted to you right now. ♥️
The cat just did me in. I need you to come to Australia and help me build my dream. 💕
Might want to think about doing a mechanical cleaner. Some sort of Arduino based spinning brush that runs ever few hours. Could even use the hydro system to power it with some small battery’s. Probably overkill and it would be easier to walk up there each day but it would be nice to be able to leave it for a few days and not have to worry about it
you could add a valve to the backside of the screen to blow water through the backside to clear it every few hours could be as simple as using a ram pump to move the extra water into a small tank when tank is full it tips sending water down the pipe it blast out the backside of the screen clearing stuff off
Fashion a water wheel rake system in front of the collector...before the levy....to grab debris and sling it over top.....like a rake....just an idea..✌
love your supervisor.
Absolutely love what you are doing!
you are sooo clever, really appreciate all you do.
Love this project. I think you can squeeze a bit more power out of that ;-).
You could put expanded sheet under the fine screen to provide support so it doesn't dish out like that. Expanded sheet (has large diamond shaped openings) would not screen out much, but it's stronger and would allow a lot of water through while supporting the screen you have now.
You work is absolutely amazing Kris. You should be proud 👍🏼 Amazing work
Hello, a bow screen is a proven method still used everyday in various industries.
Most important, you should use a wire screen instead of a mesh screen.
(special wire screen with triangular wires sligtly shifted one from another).
The angle of the screen has be be steeper and in a curve.
All the water should go trough the screen, the excess water you dont need can be separated by an overflow underneath the screen.
Hi Kris, great job. Tig welding was more than acceptable. An idea for the screen - could you make a "screen" out of 1mm mild steel (to test the idea out) like 20mm tall and run them 1mm apart all the way across, with the 20mm strips of steel running the same direction as the water flow. Sort of like a miniture cattle grid across a gate way. If you know what I mean. Probably crazy time consuming but might work. Or a variation of the idea... I don't know 🤔. Keep up the good work buddy. Never easy in the pissing rain. 👍👍👍
my sugestion is:regular watermill would
use the same water . pipes wouldn't burst in the cold.
Just in time the rain is coming amazing!!!
Hi Kris, I really enjoyed this video . Great design and very well built. Maybe it just needs to be longer? Just thinking your're missing out on a lot of water that's spills off the front . A longer one will offer a gentler gradient too.
Fantastic job. Stay safe
Your a very clever guy Kris
Hi Kris, I have two ideas for the screen:
*Maybe make an acceleration plate that goes above the wood part directly to where the water enters the intake. That way the water is held closer the screen, if you understand what I mean.
* Although this would be a major rebuilt, you could experiment with different screen angles, it seems by browsing the internet most are steeper.
@Kris Harbour Natural Building You may have thought about it.
What if you got a water pressure sensor and a water height sensor in your dam? You could figure out how much you can "load" your dam for the water height and thus able to produce as much as you can for the amount of water present (little to no waste).
Tu es trop créatif, mec. C'est génial!
Hi Kris. Just a thought... how about using inverted "dimpled" punch plate as a pre screen over the coander/mesh screen ? My thinking is that the raised edges of the dimples will make the heavier debris flow past, the dimpled holes allow plenty of flow through and the raised edged will also cause enough turbulence to dislodge any lighter materials that settle over the holes. As to future kit form design I would think about a two part weir cap. One part overly long (cut to suit application) with a 90 degree bend to sit over the weir edge with the 90 degree upstream facing down and then overlap that over a "30 -45" degree overly long (cut to suit application) accelerator plate. Just my tup`pence worth matey, there's not much that we can teach you about this malarkey ! = ) Hope all is well. Regards from Vienna.
Random: If you were wanting to get the knots out of your hair. Start at the bottom and work up to your head. Take your time and do it in small sections. Gently pull knots apart. Sorry if Im being forward, just disregard.
Good work! Grats.
