Following your dream's... No matter how long it takes to become reality, just follow your dreams... Dreams and imagination are the fuel to build a great mind. Great work Kris.
Kris loves problems to solve. By nature he feels it as an opportunity to improve and to learn. Super educational for so called the modern high speed managers out there.
Nice example, Just bought 20 ac waiting for snow to melt and My power hydro project goes into full swing . Like the quality put into your set up, good job
Marcin Krukar That would actually be Steam driven turbine power but some of the greatest marvels of hydroelectric engineering like the Hoover dam started just like this: One guy with a need for power.
I'm gonna be pedantic, and mention that the primary purpose of Hoover is not and never has been power generation, but rather flood control. That power station *is* a really nice side benefit, however. :)
kris, you amaze me how handy you really are!! the most i ever learned was how to saw a board after measuring....lol....i have to say tho, i think your pipe is going to get clogged w/clay & sand/silt in about two months because of how small some of the joints are....even w/a filter or screen your still going to have to have to flush it out sometimes to keep it running....it's going to make it difficult to get to the pipe if you concrete it in tho, but i guess you thought of that??? Can't wait to see it up & working/running...thank you for the video as always!!!!!So happy for you that you finally achieved your dream homestead!!!!wish more younger people were like you nowadays!!! :)
Thanks pat. i dont think there will be any build up in the pipe. you have to remember that the water is going to be moving very fast as it tappers down. in fact it will be moving at a speed of 3 meters per second by the time it gets to the smaller pipe. and the only place on the whole system where it goes up hill is right at the turbine. so pipe clogging i dont think will be an issue. but that does means that some silt and clay is going to be blasting out of the nozzle at 22 meters per second and that will slowly wear down the pelton wheel and nozzle. so minimising that will give the turbine a bit longer life.
Kris Harbour I agree with you kris.... there won’t be build up of silt..... with regards to wearing of the pelton wheel.... that would have to be a lot of debris in the right conditions.... I think your talking years of use before any significant wear... the cost of the pelton wheel seems expendable.... on a side note, would you consider doing a video on how you decided to come about this life.... have you given up your old job etc... thanks in advance
You asked in a previous video how to get the fine grit out of your water supply, a settling tank up near the collection point might serve. One of those plastic tanks in a metal frame might be big enough, if it is at the same height as the collection point there shouldn't be any pressure on it. I am really enjoying this build.
Glad to see your using a Mattocks or "grub hoe" for digging. The best tool man has ever invented after the rifle and shotgun. I see your dream finally getting dialed in.
A bit off-topic Kris, but I sincerely hope you have a very good method of cleaning those jeans. I've been up to my waist in muck but you have set a new standard. As an engineer I'm enjoying watching you 'pervert' theory into practical reality. That's what engineers do, ya know. With the limitations you have set for yourself taken into consideration, I admire the progress you have made. (Even though I regard a timber-frame/mud and wattle powerhouse as utterly ludicrous, I simultaneously find it to be absolutely beautiful.) Carry on mate, and don't be surprised if those jeans begin walking on their own... :-)
Haha thanks for the comment. i dont really go much further than just getting the bulk of the mud off in the stream :D i have some work trousers for cleaner work these are muddy work trousers and they mostly stay muddy :D
Living the dream, You da man ! Great job Kris, I`m impressed with your accomplishments. Thank You for sharing your videos with us, it`s such a learning experience ! ATB
Hindsight being what it is, I can't help but think that 4 or 5 sandbags would've been extremely useful. Use them to divert the water, then use the same ones to hold the pipe down.
The Land of the free as a name for the states does not really fit anymore does it. some of the things i have been reading about regarding the making of living off grid against the law in some states. and rules around collecting rain water. very sad. thanks for the comment.
I had quite a few people tell me that all my calculations were wrong and what i was doing would never work so i am guessing it is those people. dislikes are just a part of youtube. some people just like to do it for the sake of it, some are jealous, some are miss informed.
Kris Harbour haha just had a funny thought, it could be the small handful of super rich who profit from energy sales that dislike your rebellion against the system.
I can tell you why cafod. People are jealous and ignorant. You can learn so much from watching these videos (right or wrong- 99% right). Any person hitting the thumbs down key needs to grow up.
I love the plastic compression connectors your using & the needle valve set up on your outlet to the turbine. The seem very sturdy & very easy for use with The penstock as well as the inlet & outlet connections. What are the make & models of the equipment & who is the MFG? I’d like to see if they are available in the US at a reasonable price...
A lot of great work.. I can't help but think it would have been much easier and less precarious to put the power house on dry ground and simply create an outlet shoot to return the water to the creek. Rather than build directly over the creek...
Everything looks great Kris! Just wondering though why build the generator house on the stream? Seems like it would be safer to build it off stream in a low area to avoid flood risks damaging the building and equipment. Build a catch basin to bring the used water back to the stream..
Because in the stream where the building is is the lowest point within my boundaries. If I had put it anywhere else i would have lost over a meter of head. And it is safe there it can’t get flooded.
Hi Kris, May I suggest something to you... You mention you will go back and concrete in your piping I wouldn't and would like to share why... I built a hydraulic ram pump and found that my 2 inch pipe would clog up with silt on occasion and it was a bummer getting it unclogged because the pipe run was a total of 120 feet (36.58 meters) long and if it had been cemented in it would have been much harder to clear the blockage... I was able to pick up sections of the pipe and shake it up and down and it cleared itself easily... You can snake the pipe if you do cement it in...Food for thought project is looking awesome buddy... Peter
Just a bit of a tip! If you put concrete over the pipes if you ever get a leak in your pipes or connections its going to be a nightmare to get the concrete out to fix the leaks
@Kris Harbour Natural Building: HI, just discovered this series, and just finished this episode. By my knowlegde you dont loose anything because of redused pipesize. Actually you will probably gain a higher pressure at the nozzle, making the turbine able to maintain the rpm (and output) even if you put a higher load on it. Because the intake fills the same amount of water into the pipe, and as long as the fluid is flowing, gaining momentum down the hill. And then, at the end where you have a smaller pipe, this momentum pushes even harder. Why do you think the nozzle is so much smaller then the pipe? love the vids, tho.
@@KrisHarbour Ok, I'm not going to argue with you. You are the one that actually did this, so I recon you have done the needed research. I've been informed by commercial hydro-plant-operators during a tour last week. But maybe it only applies to larger (commercial) setups or higher head? Keep the good vids comming. Kris.
I still have 100m of armoured cable to run. 200m of plastic pipe in 2 400kg rolls, wiring and testing.... it’s going to be a while yet before it’s running
hi i am from nepal .i am thinking .i have water source .from 600 meters distance from 25 mm plastic pipe . Its head height is about 200 meters .Can I generate hydroelectricity from that source and if I can, how much electricity can it produce?
No it wont. you would think that would be the case because it seems like it would when you think about it. but no. the presure is the same regardless of pipe size (when the water isnt moving) as soon as the water is moving there is a pressure drop from pipe friction. so this smaller pipe will cause a pressure drop when the water is flow. and that is where the loss in efficiency comes in that i was talking about.
Considering your tools, future workshop power requirements, is the combination PV cells, hydro and wind turbine power generation going to be enough to allow you to build without running the generator or will you always have to rely a bit on gasoline/ petrol?
it will be somewhat weather dependant. i will only be able to do things like using a table saw for hours on sunny days/rainy days or generally when the stream is flowing well. on a dry summer day that is overcast i would have a lack of power for much more than lights and basic stuff. but those days are very few and far between. most of the time i have sun or rain. and it only has to rain every few days to keep the stream full and the hydro going well. so i wont be dependent on the generator once everything it set up. i will just have to work around the weather.
It’s a little more difficult for me. Some of my tools require 50 amp service. As much as I know about woodworking, I have to say I’ve never considered using my chainsaw the way you do. Going to try that out as well as break out the old chisel set.
I am no expert, but is having the turbine at a higher elevation than the pipe at the end going to lose some power? It's difficult to gauge how far the intake is to the powerhouse, could you give us a tour of how long a distance that pipe is going in order to build up water pressure? I note another comment below about width of pipe and clogging with clay, again I imagine you have a plan for that if you intend to concrete it in? Great work as always.
yes there will be a little bit of a lass there but that was factored in to the calculation. there needs to be some space under the turbine so its a loss that has to be there unfortunately. the pipe length is 200m in 110mm pipe, it will have 24psi by the time it gets to the turbine. i did a video explaining all the calculations and pipe sizes.
Why are you using compression joints? For the price of a couple of those bigger joints you could build the whole thing in 4 inch PVC sewer pipe with glued joints with any curves or junctions specifically designed to reduce flow loss. with clean outs and inspection points ready made to measure.
You have 16meter of head, four inch schedule 80 sewer pipe operating pressure is 20 meters of head, (burst pressure is 100meters) Smaller diameter pipes have even greater pressure resistance. . Sewer pipe is designed specifically to reduce efficiency losses and turbulence (because shit sticks to areas of turbulence or efficiency loss as you demonstrated with the leaves getting stuck by the turbulence below the lip of your upper filter). If glued properly sewer pipe has no significant increase in efficiency loss at joints especially when compared to compression joints at radius reductions or branches. not forgetting that benefit of being able to put in the occasional inspection port and clean out. I was not talking about you 100m pipes just the hardware at the ends. You also got hung up on the efficiency irrelevance, all the pipe is doing in your system is transferring water pressure not water velocity, since you have a small valve at the turbine end as long as the pipe can deliver slightly more water than can get through the valve nozzle it would keep the system working at its maximum and water being wasted by overflowing at the collection end. ie if you cannot get the pressure reading to drop when the turbine is at maximum then your limiting factor is turbine design not water delivery. If you measure how many gallons per minute can be captured without loss at the top and compare it to what is exiting the turbine at the bottom when the valve is fully open (if there is a significant difference you could add a second turbine) It is only if the turbine capacity closely matches what could ideally be collected at the top but the pipe is not able to deliver the flow would the efficiency of the pipe ever become a factor otherwise your other losses dwarf those caused by pipe design The point is mute since you have already installed your system, I was just pointing out that you chose a rather expensive pipe jointing option.
thanks for the long comment but you are very much mistaken in how pipe loss works. as soon as any amount of water start moving through a pipe the pressure will drop. if it is a small pipe with lots of joins and bends the presure will drop by alot. if it a massive pipe in a straight line the pressure wont drop so much. so the sive of the pipe, number of joins and straightness of pipe directly relate to how much loss there is. yes i have an adjustable valve. that means that my efficiency will go up when the flow is lower, and down when the flow is higher. it sounds like you are saying pipe size does not matter as long as it is slightly bigger than the nozzle and that is completely wrong. unless i have misunderstood your comment.
also as far as the joins are concerned there are only 3 compression fittings. £150 cost and they are the right thing for the job. strong, pressure rated way over my requirements and uv treated. why would i try and save £50 and make my system just about rated for it pressure and have two different plastics joined together (PVC to MDPE) pvc is much more brittle. all to save £50. im sorry but all the points you have made make no sense to me at all.
Pipe size is important, up to a point, that point being "can it supply the nozzle when it is at full flow". if it can supply more water than can get through the nozzle then the efficiency of the system is being throttled by the nozzle size i.e. the water in the supply pipe is not flowing as fast as it could and although this will show on paper as a increase in pipe efficiency it will result in reduction of 'system' efficiency which makes the pipe efficiency mute. If you are unable to make the standing pressure at the nozzle drop when it is fully open then the pipe is supplying more than the generator can utilize so pipe losses are effectively irrelevant because the pipe is not the system bottleneck. similar points can be made about the collection system if the collector is unable to collect enough water to keep the pipe full if it was disconnected at the bottom and allowed to flow freely, then again the pipe is not the bottleneck. that is why I suggested you measure how much you can collect compared to how much is leaving the generator. a 4inch pipe is unlikely to be drained by a half inch nozzle. As for the joints, fair enough if you want to spend the money that is your choice, however out of interest what is your estimated payback on your total project. and why drop the pipe diameter so far away from the generator house, is the water velocity gained actually being transferred through the nozzle or is it just a potential bottleneck if you do match your generator output to collector input in future. if your filter fails and the system becomes reduced or blocked do you have a method to clean it out?
i just make it up as i go along. i just visualise something in my head have many sleepless nights thinking about it. then i just start working on it and keep at it until it works. i have no training in any of this.
hello, really like what you are doing, very instructive and as you said "entertaining" Haha! As I suppose it take you an enormously amount of time and it would be very interesting that at the end of your project you make a kind of report of how many time did you put on the project and how much did it cost to you. Also ( don't know if you already did) it would be nice to know where did you learned the skills you needed ( for examples the books you used or the differents websites ). anyway very good job and sorry if i made any spelling mistakes, greetings from france!
yeah sure, i can make a video going over all the costs and things for you. i will do it once the system is complete of course. as for learning i just do things. i just start a project and learn as i go. if i dont know something i get on youtube and learn it. after years of doing this i have built up quite a varied skill set. my advice is to just pick a project that pushes you and just start. :)
did you watch the first video? i did a basic explantation on that video. but its somthing like this....www.google.co.uk/search?q=micro+hydro+system&source=lnms&tbm=isch&sa=X&ved=0ahUKEwjRu-zQvNDYAhWrAsAKHV91Cv0Q_AUICygC&biw=1434&bih=799#imgrc=A-Q0PPpP5uoqfM:
Just a quick one, did you get permission to do that. The reason I ask is that the guy at work has a large plot of land with a stream running through it at a good flow rate. He looked at putting a small water wheel to give a small amount of electricity for his dog kennels in winter, when the heat lamps are on. From what I remember you do need permission( environment agency? ). I Will ask next time I see him and re post.
Hi Kris, my Pelton générator is runing now. I can produce up to 715 Watts ! I saw you change your generator, is it from US, and what is the model ? my last video: th-cam.com/video/JDcU4jbmAnI/w-d-xo.html
im just watching now mate. my french is not so good but im enjoying it anyway :D really nice system! i wish i had that much head! i believe we are using the same us made alternator.
81M of head! that is crazy. although if i could make a constructive criticism your pipe loss is quite high. you are loosing 20m of head in your pipe. if you wanted to make even more power you could upgrade the pipe size in the future. but im sure you already know this... really nice system cristof. well done.
not 81m, but 64m . the manomiter is faulty, it start at 1,8 bar? I will change it. My US generator is 4000W / 240 volts, but in the real life, it's less. Never trust the seller. I will use it at about 300W, that's 7200 Watts/hour a day. I am waiting for your result.
hi Kris, I will use battery, lithium ion battery, I am building a powerwall made from 18650 battery from old laptop. I have a few video about it in my chanel. th-cam.com/video/jyxPUEhEwOM/w-d-xo.html? my filtering is simple, I juste have to clean the small tank every two month, the pipe outlet is in the midle, and all the sand go to the bottom of the tank
I love the plastic compression connectors your using & the needle valve set up on your outlet to the turbine. The seem very sturdy & very easy for use with The penstock as well as the inlet & outlet connections. What are the make & models of the equipment & who is the MFG? I’d like to see if they are available in the US at a reasonable price...

Enjoy ure dream Mate and go for it!
I was hoping you would get it up and running!
I still have 100m of armoured cable to run. 200m of plastic pipe in 2 400kg rolls, wiring and testing.... it’s going to be a while yet before it’s running
Is that a mouse running at the back of the shed at 10:12-10:13?
cant wait for more!
You’re on it bro!!!
hi i am from nepal .i am thinking .i have water source .from 600 meters distance from 25 mm plastic pipe . Its head height is about 200 meters .Can I generate hydroelectricity from that source and if I can, how much electricity can it produce?
Wait what happened with the whole wood intake box thing?
that is at the other end of the pipe. that box feeds the pipe that come down the hill that eventually connects to the turbine.
oh so that box is further up the hill and will connect to that pipe you just put in. Right? I love your channel bro keep it up im watching everything
Will the decrease in size result in a increase in pressure
No it wont. you would think that would be the case because it seems like it would when you think about it. but no. the presure is the same regardless of pipe size (when the water isnt moving) as soon as the water is moving there is a pressure drop from pipe friction. so this smaller pipe will cause a pressure drop when the water is flow. and that is where the loss in efficiency comes in that i was talking about.
So why the bigger pipe at the top? Might be obvious but my brain doesn't get it.
Headroom for scaling
How bigher the diameter, how less friction, ones the water runs. How less friction overall, the more pressure left from the teoretical value (head)
So there is less pipe friction. Meaning higher glowing pressure and lower losses
Considering your tools, future workshop power requirements, is the combination PV cells, hydro and wind turbine power generation going to be enough to allow you to build without running the generator or will you always have to rely a bit on gasoline/ petrol?

Are you going to bury the whole drive pipe all the way up?
Planning in your head for so many years means most of the potential problems are already ironed out, it’s something i rearly do...
I am no expert, but is having the turbine at a higher elevation than the pipe at the end going to lose some power? It's difficult to gauge how far the intake is to the powerhouse, could you give us a tour of how long a distance that pipe is going in order to build up water pressure?

Because I would have to have about 50 joins all taking away efficiency and sewer pipe isn’t pressure rated. I spend months researching all this stuff.
You have 16meter of head, four inch schedule 80 sewer pipe operating pressure is 20 meters of head, (burst pressure is 100meters) Smaller diameter pipes have even greater pressure resistance.
.
Sewer pipe is designed specifically to reduce efficiency losses and turbulence (because shit sticks to areas of turbulence or efficiency loss as you demonstrated with the leaves getting stuck by the turbulence below the lip of your upper filter). If glued properly sewer pipe has no significant increase in efficiency loss at joints especially when compared to compression joints at radius reductions or branches. not forgetting that benefit of being able to put in the occasional inspection port and clean out.
I was not talking about you 100m pipes just the hardware at the ends.
You also got hung up on the efficiency irrelevance, all the pipe is doing in your system is transferring water pressure not water velocity, since you have a small valve at the turbine end as long as the pipe can deliver slightly more water than can get through the valve nozzle it would keep the system working at its maximum and water being wasted by overflowing at the collection end. ie if you cannot get the pressure reading to drop when the turbine is at maximum then your limiting factor is turbine design not water delivery.
If you measure how many gallons per minute can be captured without loss at the top and compare it to what is exiting the turbine at the bottom when the valve is fully open (if there is a significant difference you could add a second turbine) It is only if the turbine capacity closely matches what could ideally be collected at the top but the pipe is not able to deliver the flow would the efficiency of the pipe ever become a factor otherwise your other losses dwarf those caused by pipe design
The point is mute since you have already installed your system, I was just pointing out that you chose a rather expensive pipe jointing option.
thanks for the long comment but you are very much mistaken in how pipe loss works. as soon as any amount of water start moving through a pipe the pressure will drop. if it is a small pipe with lots of joins and bends the presure will drop by alot. if it a massive pipe in a straight line the pressure wont drop so much. so the sive of the pipe, number of joins and straightness of pipe directly relate to how much loss there is. yes i have an adjustable valve. that means that my efficiency will go up when the flow is lower, and down when the flow is higher.
it sounds like you are saying pipe size does not matter as long as it is slightly bigger than the nozzle and that is completely wrong. unless i have misunderstood your comment.
also as far as the joins are concerned there are only 3 compression fittings. £150 cost and they are the right thing for the job. strong, pressure rated way over my requirements and uv treated. why would i try and save £50 and make my system just about rated for it pressure and have two different plastics joined together (PVC to MDPE) pvc is much more brittle. all to save £50. im sorry but all the points you have made make no sense to me at all.
Pipe size is important, up to a point, that point being "can it supply the nozzle when it is at full flow". if it can supply more water than can get through the nozzle then the efficiency of the system is being throttled by the nozzle size i.e. the water in the supply pipe is not flowing as fast as it could and although this will show on paper as a increase in pipe efficiency it will result in reduction of 'system' efficiency which makes the pipe efficiency mute. If you are unable to make the standing pressure at the nozzle drop when it is fully open then the pipe is supplying more than the generator can utilize so pipe losses are effectively irrelevant because the pipe is not the system bottleneck. similar points can be made about the collection system if the collector is unable to collect enough water to keep the pipe full if it was disconnected at the bottom and allowed to flow freely, then again the pipe is not the bottleneck. that is why I suggested you measure how much you can collect compared to how much is leaving the generator. a 4inch pipe is unlikely to be drained by a half inch nozzle.
As for the joints, fair enough if you want to spend the money that is your choice, however out of interest what is your estimated payback on your total project. and why drop the pipe diameter so far away from the generator house, is the water velocity gained actually being transferred through the nozzle or is it just a potential bottleneck if you do match your generator output to collector input in future.
if your filter fails and the system becomes reduced or blocked do you have a method to clean it out?
Great job but you could make your own "strap wrenches" fairly easily...
Is the 11th part missing or just a numbering error? Btw, great series, I really enjoyed it.. Thank You.
great vid as always :)
How did you Learn how to do all this
i just make it up as i go along. i just visualise something in my head have many sleepless nights thinking about it. then i just start working on it and keep at it until it works. i have no training in any of this.
learn to do by doing that's 4-H motto
Pretty exciting!
hello, really like what you are doing, very instructive and as you said "entertaining" Haha! As I suppose it take you an enormously amount of time and it would be very interesting that at the end of your project you make a kind of report of how many time did you put on the project and how much did it cost to you. Also ( don't know if you already did) it would be nice to know where did you learned the skills you needed ( for examples the books you used or the differents websites ).
anyway very good job and sorry if i made any spelling mistakes, greetings from france!
yeah sure, i can make a video going over all the costs and things for you. i will do it once the system is complete of course. as for learning i just do things. i just start a project and learn as i go. if i dont know something i get on youtube and learn it. after years of doing this i have built up quite a varied skill set. my advice is to just pick a project that pushes you and just start. :)
i really dont get it how that thing work
watch the full series and you will
I'd like you to show how all this works in a simple diagram, or just give me a URL to read.
did you watch the first video? i did a basic explantation on that video. but its somthing like this....www.google.co.uk/search?q=micro+hydro+system&source=lnms&tbm=isch&sa=X&ved=0ahUKEwjRu-zQvNDYAhWrAsAKHV91Cv0Q_AUICygC&biw=1434&bih=799#imgrc=A-Q0PPpP5uoqfM:
Just a quick one, did you get permission to do that. The reason I ask is that the guy at work has a large plot of land with a stream running through it at a good flow rate. He looked at putting a small water wheel to give a small amount of electricity for his dog kennels in winter, when the heat lamps are on. From what I remember you do need permission( environment agency? ). I Will ask next time I see him and re post.
Right arm bud. :)
I should have said at the back of the powerhouse
u r a wizard XD
dude; is there anything you can't make? : )
i have never made a cake before and would not know where to start :D so yes!
Hey Kris great video. What ever happened to your girlfriend, why isn't she in your vids anymore?
Hi Kris, my Pelton générator is runing now. I can produce up to 715 Watts ! I saw you change your generator, is it from US, and what is the model ? my last video: th-cam.com/video/JDcU4jbmAnI/w-d-xo.html
im just watching now mate. my french is not so good but im enjoying it anyway :D really nice system! i wish i had that much head! i believe we are using the same us made alternator.
81M of head! that is crazy. although if i could make a constructive criticism your pipe loss is quite high. you are loosing 20m of head in your pipe. if you wanted to make even more power you could upgrade the pipe size in the future. but im sure you already know this... really nice system cristof. well done.
not 81m, but 64m . the manomiter is faulty, it start at 1,8 bar? I will change it. My US generator is 4000W / 240 volts, but in the real life, it's less. Never trust the seller. I will use it at about 300W, that's 7200 Watts/hour a day. I am waiting for your result.
are you using batteries or are you using the 240v straight to the appliances? im loving the filtering setup. very nice idea.
hi Kris, I will use battery, lithium ion battery, I am building a powerwall made from 18650 battery from old laptop. I have a few video about it in my chanel. th-cam.com/video/jyxPUEhEwOM/w-d-xo.html? my filtering is simple, I juste have to clean the small tank every two month, the pipe outlet is in the midle, and all the sand go to the bottom of the tank
HS2o (BTW, HS2 is an ecological disaster and complete waste of money)
I love the plastic compression connectors your using & the needle valve set up on your outlet to the turbine. The seem very sturdy & very easy for use with The penstock as well as the inlet & outlet connections. What are the make & models of the equipment & who is the MFG? I’d like to see if they are available in the US at a reasonable price...
