HI Kris, I’m a 3D CAD guy working in IM for 25 years.The paddles look great, but it would be worth putting 2mm fillets on the internal edge where the back of the spoon meets the connecting arms to reduce the risk of any cracks forming. In fact with Injection moldied parts, put fillets on every edge except where the tool splits. Great watching your projects, it must feel good to be off grid with everything going on in the world at the moment!
i tell ya friend, to share the benefits of your experience and knowledge with a friend like this, really cool...i don't even fully understand your advice, i realize it's a reinforcement feature. i'm sure the guy in the video gets it. i thought it was so extraordinary and cool that you shared your wisdom like this, and i had to comment as such. bravo, we all gain from your growth and skills...thank you friend.
@@KrisHarbour I'm just a viewer from the United States ... Question: where (if at all) do patients play a part with this project? I think it's cool what ya already done, doing, and excited for what's coming! Thanks for sharing your journey.
Love your endurance and resolute determination to manufacture a better product. I think your design with the more flexible and smoother nylon injection molding product will result in a significant increase of power production.
Yes, I was thinking the same thing. I think the efficiency loss due to the rough interior of the 3D printed spoons is not insignificant. It will be really exciting to see the test results on the final mold injected (smooth interior) product. I really think Kris is on to something!
You regularly blow my mind with your engineering. Especially when I remember you didn’t spend years of time and loads of your hard earned money going to Uni to learn this stuff.
Many people don't need that type education to get jobs like this done. Much of it can be learned at the school of hard knocks. Even thought there are many degreed people working at SpaceX, you see design changes almost daily in things as they learn what works and doesn't work in a specific job. Kris is doing the same sort of thing with his work as you see the " well that didn't work as expected so lets change it" and "that works better so lets incorporate it in the next design". That is the nice thing about 3-D prototype printing. You can make changes rather easily and try a new design.
I’m so proud of you! Not only did you come up with a great design that is as good as the best on the market, and then some. But you were completely honest and open with the testing. Then you learned from it in order to improve your design. I would put your creativity, intelligence and integrity against anyone I’ve ever seen. That is a formidable combination! Bravo!🐝🤗❤️
@BreatheScotland Exactly! Kris is amazing. I would rather have him design something for me than anyone I can think of. I know he would do it right and then keep improving it. Can’t ask for more than that.🐝🤗❤️
Absolutely fascinating mate! All I kept thinking while watching all this was how wonderful it is that your customers can watch this and genuinely see how much effort you are putting into making a properly high spec and highly efficient turbine! your attention to detail is exceptional and I think anyone that puts their money your way should be very safe in the knowledge, it has been spent wisely! Outstanding mate bloody good on you! Thanks for taking us along too I loved every minute! 👍👍
Kris as a draughtsman - CAD & BIM Manager who did two years for fabrication and metalwork and worked in R&D because I kept designing new products when I was in the drawing office producing drawings using the kit and saw problems on site and come up with solutions too often that they transferred me. I love the way you approach everything and wish I had picked up your carpentry skills along the way. You are a gifted individual and I love the way you explain in simple terms what and how you are testing and how you are going to modify the design. If I lived in the country with access to streams I would defiantly find myself becoming a customer of yours especially with the cost of power doubling.
honestly this is why im shopping for a property that has acreage AND moving water because i like hydro power and im gonna prob do solar and wind if i can
I have absolutely no clue what your doing but I love watching your videos! Your a genius Kris! I enjoy watching your building and creating amazing things @75 yrs young Iam in awe of your talent and ingenuity!! Your channel stays on mist of the day n nite cuz nothing else catches my undivided attention!!!
Wow, I have a feeling that over the next few years your services are going to be in high demand. More and more people will be looking to reliably produce their own power needs (hydro, solar and wind). I sincerely hope after all the work that's gone into these you get some benefit from it all, keep going Kris well done
This was fascinating, it's great how far you have come, keep on exploring we all join you through your videos. Thank you for sharing your life with us your fans!
I was pretty ignorant about hydro power, until now. Thank you Kris for explaining pretty technical knowledge to a newbie in a way I could understand. All the content you put out is valuable, no matter what it is.
Fascinating watching the testing of all the variables that go into maximum efficient output! John's test rig is fantastic. Numbers don't lie! Looking forward to your design update and its testing after what you learned in this satisfying number crunch!
amazing work and reasoning ... a walk in the woods to clear the mind and it should be all good ... I really like your vision and dedication to quality ... whatever video you will put out most viewers will watch so just do whatever is better for you ... thank you
Love your work, the world desperately needs people like yourself and helper. Keep on expanding your talents, nobody can take them away from you once learnt 👍💪👍💪
Hello Kris, it’s a pleasure and as fascinating as ever to see what you’ve been designing and making. It’s exciting to see the advantages of your slant back offset idea even on printed spoons, polished production examples will surely win the day! I hope you are both well and that your pusser is enjoying spring walks!
Once you get your designed dialed in you'll have to build your own injection mold machine. Then you can use recycled plastic and your own power to make it all in house. Very cool. My intuition says you would only need a single mounting bolt(the closer one to the spoon) if its sufficiently supported behind the spoon. Would simplify the mold and the costs associated with it and remove more material.
'''you would only need a single mounting bolt(the closer one to the spoon)'' ... my intuition says the bold farther from the spoon as it will create good tension between the spike and the bold ... but maybe there is a reason Kris is using 2 and not 1
@@kevdel Mass in motion is of great importance. I saw a carbon fiber presentation where they showed that for automobiles, the importance to fuel efficiency between stationary and rotating mass was at least a factor of four (Oak Ridge National Laboratory, USA). Carbon fiber wheels would be 4 times better towards fuel efficiency than a similar mass reduction to the body of the car. Attack the mass - one reason that the saw tooth design would be expected to be less efficient- it should weight more. But if the sawtooth support could eliminate the use of one screw, that might produce a lighter assembly.
You can't "recycle" glass reinforced nylon at home into injection molded parts. Maybe HDPE though. Not sure it would be worthwhile as he wants to sell this stuff and having parts wear out much sooner is not great for the end user.
You’re level of understanding makes me feel good. I tend to dig as deep as I can on things I’m working on. It is so cool to have you explain all of this stuff. I just think I like how you think. I don’t know what to say. I completely understand. I think alike. I make my own tools though. I can’t afford the machines you have.
Fabulous!! Kris, I love your video's and wish I could join you in person, but alas, I am in the states. I look forward to a follow up on the modified design. I've read a good majority of the comments and your followers are always so positive and like minded. They also provide some good suggestions based on their years of experience which is always thought provoking and helpful. Keep pushing forward!
Greetings from New Zealand Kris .... What an Absolutely Brilliant vidclip .... As a retired Engineer, Toolmaker, CNC Machinist etc I so wish that I was closer to you. You are so inspiring and are one of those Very Rare 'Natural Engineers' .... Just having the ability to be able to 'rasionalise' intuatively is a Real Blessing. There is Maybe something else to consider .... Something called the 'Solidity Factor' ... i.e. The ratio of the 'Active Area' as compared to the 'Open Space' between the Spoons. You can get into the situation where 'Less is More' and related to the Volume, Water Velocity and RPM.... Thanks so much for sharing your Super Interesting vidclips .... Cheers .... Keith
If you want to compare your shape modification, you should 3D print copies of the models you currently buy. That way all versions would be made of the same material, and have the same surface roughness.
Excellent video. Some really useful work you’ve done there, especially with the current energy climate. I wish I had a 40 meter head lake in the garden now.
I knew nothing about hydro before I started watching your video's but I'm finding this really interesting. I just need to buy a house with a hill and steam to make use of all this knowledge now!
I live in the middle of the high desert so these videos are fun to watch but not super applicable to me as water sources not owned by the government are hard to find But your enthusiasm for this project is intoxicating. I can tell how much effort you put into the project and Im glad it's working for you! Favorite channel on UA-cam. Keep it up!
Very interesting Kris. It sounds like your theory is very similar to a combustion engine. Focusing on inputting power (fuel) and focusing on porting the exhaust (water splashing). So water in - water out with the least disturbance. A inverted funnel to remove the waste water without influencing the water wheel. Great progress, thanks for the video 👍👍.
Thanks for putting that explanation in layman's terms for those of us who didn't study physics. That was pretty cool, or wicked awesome as we say in Boston.
... And now I find myself asking... What would Kris do???? Huge fan since the beginning. Setting out to start my roundhouse project! First order of business...a chainsaw!!! Scary but I'm going for it! Have a small stream on the property can't wait for all to laugh at! Thoroughly enjoy the vids... All of them. Stay safe everybody!!!!
Have you tried the fluid dynamics analysis tools in Fusion360? Seems like different streams (nozzle sizes) and a force sensor could tell you a lot, not to mention looking at the waters behavior based on cup shape.
Another interesting test to do would be head pressure against nozzle size, going up from 12mm to 20mm in 1cm increments and seeing what sized nozzle is best for the different head pressures you are averaging on your working setup
Awesome Kris! Now like variable exhaust turbo’s, you need to invent variable spoons that rotate for maximum power! Might be just a divot that causes water to rotate instead of forming sprays
Well done! Great result. You must be so happy and proud of yourself. Love the channel and I'm so pleased all of your hard work is showing great results. X
As long as those "losses" is coming out towards the nozle, is not a loss. What the turbine is trying to do is convert all the momentum of the water and into a rotation around the shaft, so as long as the water is moving backwards it's not a "loss" since this is exactly what you're trying to achieve!
@@KrisHarbour a) Your test was static, this behaves very differently when at speed (just add all the speed vectors and you'll see) b) It's only the upward momentum component that's a loss (it's similar for the water you deflect down - any excess speed is also a loss, and this component will be much larger!) c) didn't know the housing has so tight tolerances that water couldn't flow out to the sides? (because that's where it will go) Efficiency also depends on the rotation speed, water pressure and flow speed, so one design will have a sweet spot that is most likely not equal to any other, so if you want to do rigorous testing you'll have to plot the efficiency across speed, water angles, nozzle sizes and water pressure (and there's probably a couple of more dimensions to test as well). I think it's more important to test what's actually happening instead of trying to reason about losses in a dynamic system you can't possibly simulate in your head (don't fret - even supercomputers struggle with these kinda simulations). Either that or hire a supercomputer to do the job for you :P
Great video Kris. It was good to see you and John working together again. The numbers are impressive, can't wait to see what prototype three shows. Also, I'm dying to see the windows. Stay safe and good luck with the numbers.
Hi Kris fascinating stuff, great video as always! The smoothing of the spoon face due to injection molding will reduce the face surface area, and the amount of friction generated or captured because of it. The more surface, the more the load will be retained. Perhaps try a stepped, ridged or grooved spoon face, increasing the face area as a way of perhaps holding on to the load, increasing the load capture and thereby reducing the high pressure waste perhaps? Just a thought. It's great watching your progress throughout your journey, things are really lining up, its great to see!
Gotta be honest, I used to not really like these sorts of vids, with too much engineering involved. Just because it was kinda scary for me, scary in the sense that it's kinda difficult to grasp and it reminded me of highschool maths/physics teachers. Glad that I stuck around though, because they're my favourite video's now, just because you explain it so well and I actually understand most of the concepts involved.
Love the video Kris! Solidity ratio also plays an effect here as the speed ramps up. I think that is why the backwards slanted ones work better at higher speeds, seeing as they would have a reduced solidity ratio.
Without seeing more I cannot be sure. But I believe some of the current design will be impossible to injection mold, to much "over hang" and no draft angles for easy ejections. Still love the idea and it will be great, if you just fix so they really are able to be cast. :) And these prototyping videos are amazingly fun to watch almost as fun as prototyping yourself, keep them coming. ;)
I have been thinking about that in my design. I have even modelled the moulds (just as a test) everything has draught angles other than the side of the mounting. the holes will need to be formed with pins from the sides and its going to require some quite high forces to eject them but I think its doable as the mounting sides are not that big. Once my design is tested im will look further in to getting moulds made and if I have to change something I will start again.
This was my first view of your channel and your work. It seems very scientific and logical and I’m sure your life‘s accomplishments are many that I would admire and mimic. However, as a retired program and project Manager of highly technical infrastructure projects, as well as lots of creative projects involving machines as varied as hot rods and motorhomes as well as fine homebuilding and renovation, I must suggest a alternative for your turbine assembly; an actual turbine. That’s correct - I believe a recycled diesel engine turbocharger (turbine side only) could replace your turbine assembly with all of those plastic spoons - after all, they have been designed, tested, refined and integrated the better part of a century now and optimize performance of almost all Diesel engines in service. This application is a “solid state/closed” flow-through piped system rather than having to deal with flow characteristics through multiple spoon surfaces and mounting points that fights against itself if not precisely aligned. Compare that to a single-piece hub supported by sealed bearings connected to the generator and I don’t even know why you are still thinking of anything else after the light bulb over your head turned on after realizing this. I mean, I’ve purchased brand new surplus turbo chargers from US government surplus sales for less than $200 apiece - which is pretty cheap compared to the time and expense involved in what I saw in this single video - a 3D printer, all that plumbing to contain the splashing and all that plastic - turbos are steel and aluminum and uses a CLOSED SYSTEM - NO SPLASHING!
Brilliant! Such an exciting and creative process for you and a dream come true in the making. If your designs prove out being that significantly more efficient, I'm wondering how you'll keep up with production. Can't wait to follow your progress and looking forward to the difference all the new windows will make!
It occurs to me that, like the wheels on an electric car, it may be worth considering a cover over the bolts to smooth out the both air and water resistance. Given the speed of the turbines you are generating a lot of air resistance, not to mention water resistance from the bolts cutting through the splash. It would also visually separate your turbines from the all the others on the market. Keep up the excellent work.
While the surface may be rough the grooves all run in line with the water flow so that may also help do away with any odd vibration or turbulence you might get in a smooth surface. Total speculation but I have seen harmonics develop in small speeds depending on the system but not totally sure where they were coming from.
If your old roll of PLA prints badly it is probably because of moisture (as you said). Put in in the oven at 45°C for 1 or 2 hours, the difference in the prints when dried is incredible.
I haven't read lots into the comments, but what I believe would be a great alternative to bolting the spoons to the wheel would be rivets. Minimal mass, less chance of getting completely loose and i would imagine the cost also would be same/negligiable. Would be very quick in a production process too. Just insert the rivet and "pop" it tight. They're still removeable by drilling if you need to replace a spoon/whatever.

As long as those "losses" is coming out towards the nozle, is not a loss. What the turbine is trying to do is convert all the momentum of the water and into a rotation around the shaft, so as long as the water is moving backwards it's not a "loss" since this is exactly what you're trying to achieve!
If it goes up it will come down again on top of the turbine. that is loss. a turgo turbine should have all the water exiting out the bottom.

a) Your test was static, this behaves very differently when at speed (just add all the speed vectors and you'll see)
b) It's only the upward momentum component that's a loss (it's similar for the water you deflect down - any excess speed is also a loss, and this component will be much larger!)
c) didn't know the housing has so tight tolerances that water couldn't flow out to the sides? (because that's where it will go)
Efficiency also depends on the rotation speed, water pressure and flow speed, so one design will have a sweet spot that is most likely not equal to any other, so if you want to do rigorous testing you'll have to plot the efficiency across speed, water angles, nozzle sizes and water pressure (and there's probably a couple of more dimensions to test as well). I think it's more important to test what's actually happening instead of trying to reason about losses in a dynamic system you can't possibly simulate in your head (don't fret - even supercomputers struggle with these kinda simulations). Either that or hire a supercomputer to do the job for you :P
Nice to see a project being tested on a test rig, to get repeatable numbers.
Great video Kris. It was good to see you and John working together again. The numbers are impressive, can't wait to see what prototype three shows. Also, I'm dying to see the windows. Stay safe and good luck with the numbers.
Hi Kris fascinating stuff, great video as always! The smoothing of the spoon face due to injection molding will reduce the face surface area, and the amount of friction generated or captured because of it.
The more surface, the more the load will be retained. Perhaps try a stepped, ridged or grooved spoon face, increasing the face area as a way of perhaps holding on to the load, increasing the load capture and thereby reducing the high pressure waste perhaps?
Just a thought.
It's great watching your progress throughout your journey, things are really lining up, its great to see!
Awesome video Kris. Thanks for sharing it👍👍👍👍👍😺🤗🐺🇺🇸
Gotta be honest, I used to not really like these sorts of vids, with too much engineering involved. Just because it was kinda scary for me, scary in the sense that it's kinda difficult to grasp and it reminded me of highschool maths/physics teachers. Glad that I stuck around though, because they're my favourite video's now, just because you explain it so well and I actually understand most of the concepts involved.
Great test and interesting design features
Love the video Kris! Solidity ratio also plays an effect here as the speed ramps up. I think that is why the backwards slanted ones work better at higher speeds, seeing as they would have a reduced solidity ratio.
Congratulations! You're well on your way. Hope to see coanda screen intakes in the near future too!
Love your longer more detailed videos! Yay 😀
Massive strides my guy, good job.
Fascinating and pretty cool, too. Thanks, Kris. 👍🙂🌊
👍👌👏 Extremely well done! Congrats! Best regards, luck and health.
Italian engineers: "these are the best spoons on the market."
Kris: "really? I'm something of a scientist myself"

Without seeing more I cannot be sure. But I believe some of the current design will be impossible to injection mold, to much "over hang" and no draft angles for easy ejections.
Still love the idea and it will be great, if you just fix so they really are able to be cast. :)
And these prototyping videos are amazingly fun to watch almost as fun as prototyping yourself, keep them coming. ;)
I have been thinking about that in my design. I have even modelled the moulds (just as a test) everything has draught angles other than the side of the mounting. the holes will need to be formed with pins from the sides and its going to require some quite high forces to eject them but I think its doable as the mounting sides are not that big. Once my design is tested im will look further in to getting moulds made and if I have to change something I will start again.
@@KrisHarbour Sounds great, I wish you all the best. :)
This was my first view of your channel and your work. It seems very scientific and logical and I’m sure your life‘s accomplishments are many that I would admire and mimic.
However, as a retired program and project Manager of highly technical infrastructure projects, as well as lots of creative projects involving machines as varied as hot rods and motorhomes as well as fine homebuilding and renovation, I must suggest a alternative for your turbine assembly; an actual turbine.
That’s correct - I believe a recycled diesel engine turbocharger (turbine side only) could replace your turbine assembly with all of those plastic spoons - after all, they have been designed, tested, refined and integrated the better part of a century now and optimize performance of almost all Diesel engines in service. This application is a “solid state/closed” flow-through piped system rather than having to deal with flow characteristics through multiple spoon surfaces and mounting points that fights against itself if not precisely aligned. Compare that to a single-piece hub supported by sealed bearings connected to the generator and I don’t even know why you are still thinking of anything else after the light bulb over your head turned on after realizing this.
I mean, I’ve purchased brand new surplus turbo chargers from US government surplus sales for less than $200 apiece - which is pretty cheap compared to the time and expense involved in what I saw in this single video - a 3D printer, all that plumbing to contain the splashing and all that plastic - turbos are steel and aluminum and uses a CLOSED SYSTEM - NO SPLASHING!
very interesting and thorough Kris good video.👌
Brilliant! Such an exciting and creative process for you and a dream come true in the making. If your designs prove out being that significantly more efficient, I'm wondering how you'll keep up with production. Can't wait to follow your progress and looking forward to the difference all the new windows will make!
It occurs to me that, like the wheels on an electric car, it may be worth considering a cover over the bolts to smooth out the both air and water resistance. Given the speed of the turbines you are generating a lot of air resistance, not to mention water resistance from the bolts cutting through the splash. It would also visually separate your turbines from the all the others on the market.
Keep up the excellent work.
That sounds like an excellent idea
Yes, perhaps a shrink wrap would be light and sufficient.
Ingenious design and build
I know it's only for prototyping but you can use "PLA+" instead of PLA, it's less fragile but prints as easily as PLA.
Abs is also cheap and usable option if your printer can handle it. But pla shows working just fine for testing, so only if needed.
While the surface may be rough the grooves all run in line with the water flow so that may also help do away with any odd vibration or turbulence you might get in a smooth surface. Total speculation but I have seen harmonics develop in small speeds depending on the system but not totally sure where they were coming from.
Very interesting you give me courage to try things for my home
It looks better than the old style and your life and the world is going to change in a big way .
If your old roll of PLA prints badly it is probably because of moisture (as you said). Put in in the oven at 45°C for 1 or 2 hours, the difference in the prints when dried is incredible.
Now it gets really scientific!
:-D
Nice hydro jet lab at John's workshop...wow...
Great progess, thx for showing!
:-D
I haven't read lots into the comments, but what I believe would be a great alternative to bolting the spoons to the wheel would be rivets. Minimal mass, less chance of getting completely loose and i would imagine the cost also would be same/negligiable. Would be very quick in a production process too. Just insert the rivet and "pop" it tight. They're still removeable by drilling if you need to replace a spoon/whatever.
