Powering An Old Mill - 1.5 Kw Lake District Overshot Waterwheel Project Part 2

[@SkyDenali]

Hi Kris, regarding the water splashing over the wheel, years ago when I was working at a small gold mine, we would attach a heavy rubberized tarp (maybe 8mm thick) to the top of the trough which draped over the top of the sluice to prevent splashing, essentially creating a cowling. The tarp was the same width as the sluice (or wheel in this case) and maybe a meter long and rode on top of the flow of water. It created a really smooth delivery.

[@KrisHarbour]

I have seen that before actually. I might give that a try when I back there next. it will be interesting to see if that would help. thanks for the comment.

[@PeterLee-zn3jl]

Maybe alroper screw driven sluice gate...and an adjudtable spillway lip that will stop side losses and aim at correct angle and depth onf water drop...why not make a curved corner out of ss steel and ckntain overslill ..?

[@markschattefor6997]

@@KrisHarbour I'm wondering if it is necessary that the spillway they build follows the original flow. What would be the problem if you would make it straight and adjust the wheel to the right angle? Okay, maybe you have to put new footings in the riverbed. But it is also possible with a few beams and glueclamps on the existing structure to straighten the spillway, and with two planks you could support the wheel temporary, after all it is an experimental setup.

[@invest48]

@@markschattefor6997 Good point. The architect of this project has missed fluid mechanical principles, no turmoil, no bubble. So simple to design a straight stream from the reservoir to the wheel. Is the debit of the water the same on each extremity of the wheel, I doubt it.

[@_CAT-lg4sr]

Met a man who was a retired attorney from New York city. He bought an old ( 1800's ) mill and 30 acre millpond with a high flow rate in a rural part of Connecticut, USA. The property included a dozen or so workers cabins. He restored all the cabins to rentals and converted the mill into his private residence. He converted the site of the old rotted out wheel to a down draught 6 foot diameter vertical shaft turbine with about a 20 foot head column over top of the turbine. The 2400 volt 3 phase 250KW alternator was mounted in a generator house over top of the turbine. Power went to an electric distribution building and transformed to 120/240 for the residences and another transformer for 120/208 3 phase for his shop building. Excess power feeds into the grid. Hydro electric power rocks!

UK has numerous sites where anything from a few kw of power to a few tens of Kw can be generated without environment harm. River Teign has a couple of sites with archimedes screw generators. There are others that could easily accommodate water wheels or turbines. River Teign (a small spate flow from east Dartmoor) is important for migratory fish but so much could be done without hurting any fish.

[@Obermuhle]

Hello Kris, great project :) I built a water wheel with an electrical output of 13.5kW. Runs 24/7 since 2012 at up to 40,000kWh/year. What I notice about your water wheel is that the water falls too far into the wheel and you haven't provided any ventilation. The water jet hits the blade at almost a 90 degree angle. It is recommended to make the wheel slightly wider than the channel so that air can flow away to the sides. The kink in the channel creates a wave that swirls the water as it flows into the wheel, this should be fixed. The water should flow into the wheel just before the upper apex at as shallow an angle as possible to avoid this impact effect. You can make the side rim a little wider than the effective diameter of the wheel, which acts as a side splash guard. You should keep the bearings well covered as they rust fairly quickly. Use a fat that does not combine with water, otherwise an emulsion will quickly form. Many greetings from the upper mill HUBI :) kzbin.info/www/bejne/gGaqeYCwfrZ6d5I

[@lukejay]

Kris, this is BRILLIANT! Yet another of your videos that I watch in awe. Just a quick note on the electrical box at the Generator end - with that copex entering at the top, you'll end up with water ingress. The IP68 box will end up trapping the water inside and as it's the first connection, it'll short the generator out and cause quite a bit of damage. I'd suggest bringing both the generator and the output cables in from the bottom, and ideally fitting an isolator switch as close to the wheel as possible. I hope this comes across as constructive criticism. I'd hate for such a small error to cause any damage. Keep up the good work!

[@avantgarde619]

I would have used a rubber seal tight tubing from the box to the conduit instead of the galvanized MC cable.

[@wardfiction5693]

This was my thought.,... I probably would have wired a 3 core shielded cable to the alternator and had less conduate. or have gear and shaft system back to the room where the isolator switch was and had all the alternators and such in there..

[@garyviveiros2557]

So-o-o, be sure to silicone-seal the connector to form a better seal against water, and mist incursion. Could use water tight connectors and outdoor flex cable that has a plastic flex jacket.

[@69Buddha]

That whole system is so intelligently designed, and I love how you put it together like it's an art piece -- because it IS that too!

[@Robert_DeVille]

Hi Kris - just a point to consider. If you want 1.5kW out of the alternator, setting the voltage to 100V means that you are essentially generating 15A. It is possible that this is too high for your alternator stator (without me knowing the nameplate rating of course) & the current is causing the windings to get hot, but unfortunately, this also increases the resistance in the windings & this makes the problem worse. The heating effects from the increased resistance & reactance of the windings can be reduced by decreasing the current & increasing the voltage without power loss & you might find your efficiency improving. Something else to consider is the conductors from the alternator. If the cross-sectional area is too small for the current being generated, this will create additional problems & also check the resistance & tightness of your electrical connections. Another point to consider is the flow of heat from the stator heat sinks on the casing. From a still image of the vid, there doesn't looks to be any air gaps in the casing, so if your cowling around the alternator is preventing the heat escaping &/or not allowing a reasonable air flow across the casing, it might be trapping the generated heat which could also have an effect. However, it looks fantastic & you should be justifiably proud of yourself - well done sir!

[@greggv8]

Gearing up the alternator speed would make it worthwhile to make a fan to mount onto the alternator shaft. Make a disk of sheet metal then cut some radial flaps to bend. Even if it only moves a little air over the alternator it would keep hot air from stagnating under the cover. A hole in the top, covered by a plate spaced up a bit and larger than the hole, would let heated air out. Would want to put a temperature sensor on the alternator to test if the fan helps any.

[@SaltGrains_Fready]

@@greggv8 that's what I thought of also. The air inside that large cover must me kept moving. In the dead of winter it will not be much of a need but on the warmest days of summer that will burn out with forced air over the unit. The only other ideal solution is an alternator with a water jacket that can take a small hose from the sluice and feed some water over the alternator and let it be water cooled. That's a different design concept.

[@KEhydro]

This is a run-of-river scheme and all r-o-r installations have changing water availability through the seasons; setting the inverter to work in 'constant voltage' mode was never going to allow the wheel to work in all seasons: when water is scarce, the alternator pulley may not turn sufficiently fast to generate the 100v he set, whilst when water is plentiful, as in the video, and as @old-seadog has said, the current is too high and risks damaging the alternator. Kris's plan, at the end of the video, is to increase the size of the drive pulley in order to get a higher rpm at the alternator (and thus higher voltage) whilst achieving the slow rpm he wants at the wheel. This would provide the combination of higher voltage / lower current which will see the alternator not getting overheated, but it risks the open circuit voltage, - the highest voltage which could ever be produced when the alternator is not under load, - being too high. Grid tied inverters are rated to receive a maximum dc incoming voltage of around 600 v; if changing the ratio of the pulleys makes the open circuit voltage encroach on the maximum permitted for his inverter, then some form of voltage capping will be needed to cover those times when the inverter is going through its self-check before connecting to the grid, and for when there is a grid outage. There are always 'trade-offs' to be made, - a trade-off being "a situational decision that involves diminishing or losing one quality, quantity, or property in return for gains in other aspects".

[@Robert_DeVille]

@@KEhydro An excellent explanation sir, I love generator theory (& transmission, transformers, protection, switchgear, etc & yes, I *am* _that_ dull!).

[@greggv8]

@@KEhydro It needs a two speed drive between the wheel and the alternator. Fix two pulleys on the wheel shaft then have the pulleys on the alternator shaft run on bearings. Fit a clutch between the alternator pulleys to engage one or the other or be in neutral. When one alternator pulley is engaged, the other one spins independently from the shaft. The extra tricky bit would be automating the shifting to accommodate two ranges of higher and lower flow, and shifting to neutral when there's not enough flow. Also useful would be controlling bypass flow for when there's too much water to run through the water wheel.

To add this the good points made above, a back shot wheel has the highest efficiency of all the wheel designs.

Lovely job. When you change to flow direction in the trough, the momentum causes the water to climb to trough side. There are several ways to reduce or eliminate this - the easiest is simply raising the obtuse side of the trough - e.g. the bottom of the trough would not be horizontal any more. But that would require quite a bit of twisting of the trough to avoid the overflow. There are two ways to get power out of the water - the first is gravity alone, which appears to be what you desire. The other is making use of the momentum of the water as well - which in many cases provides far more energy than you will get from gravity alone. But if esthetics is more important than efficiency, that is fine. The alternator/generator getting really hot means that the method you are using for wheel rotation rate is not proper. Your controller is forcing the generator to operate at reduced efficiency - which means it overheats. Instead, you should probably be running the generator at close to the rated operating rpm and controlling the power output by adjusting the input water flow volume. Keep up the experimentation, such efforts are always a joy for me to watch.

[@canadiannaturalist6369]

I hugely admire your workmanship. The concept popped into my mind when I was watching your "flow slow-mo" and I'm absolutely sure that if you get the water input closer to a laminar flow, you'd have way more efficiency. turbulence=efficiency loss.

Hi Kris, many thanks for the video - the engineering here is truly awesome and I never realised all the intricate adjustments that are necessary to enable it to generate maximum power! Looking forward to the next episode of this project. Congratulations on building this system.

[@adrianlane4256]

One of the top ten projects I’ve ever watched on KZbin, absolutely brilliant. The build quality is top notch and any glitches totally understandable on a unique first build. Well done to you and all involved. Just need to find a location for me to commission one 😂

[@SquareOneForge]

This is awesome. I am loving this build series. Well done mate!

[@frankiepitt9135]

I’ve been reading the comments on this video and I’m amazed just how many water wheel experts there are out there.

[@davemurphy2020]

It’s not rocket science

[@maurice07Birkin]

Loving this build as much as your barn Kris. I am a retired Fitter/Welder so really enjoy all your build work and like how you design your projects, then reassess/redesign as you progress. Maurice

Hydroelectric power plants from 5-100 kW and more. efficiency-99%. kzbin.info/www/bejne/e5XRdKJvp7SJl9E

[@blobstrom]

Amazing Kris. I can watch this content all day (if my wife let me).. What you constructed is amazing. My only minor tweak would have been to ensure the cable exit from the alternator would have been underneath the electrical box, even though it does have the metal cover when finished. Water will always find its way into a top entrance hole..

[@gregorythomas333]

This is an amazing project...very nicely done! You might want to consider running an ethernet cable through the conduit and install some monitoring like couple of temperature & speed sensors. On the house side you can use an Arduino to read the data out and possibly send commands to change the settings to adjust the load. A possible solution for the excess power& to slow down the wheel could be to dump the extra load into one or two water heaters...that should help with the overspeed.

[@garyviveiros2557]

That's great! One of the biggest needs is for hot water so you could run those into a pre-heat tank that feeds a water-heater tank made to support solar water heating. Pretend the pre-heat tank is a solar water heater and plumb it into the main hot water tank made to support solar heating.

[@Itssmial_Ova]

Congratulations Chris, I've been watching since day dot. What you've accomplished here I know is years of hard work and dedication. I remember you saying you'd eventually love to get into the Hydroelectric business and here you are doing that. Watching your bare land turn into a home, Then a smallholding, then a successful small business has been very inspirational. Makes me reflect upon my time seeing all you've managed to accomplish.

[@TomTurner704]

Great job! The chute is problematic. In air-handling systems the flow rate in ducts with sharp corners are improved using turning vanes, a series of curved rudders running across the corner. The discharge should be a steel fabrication adjustable for length and angle, and perhaps a little bit of narrowing.

[@Riceman-o1p]

Thank you father

[@davidcurd987]

Hi Kris, great work! One way to stop the water overflowing at the bend in the sluice would be to put in thin guide vanes. If you slope the leading edge it would stop debris from building up. I’m a pump and turbine design engineer so if you want some advice on hydraulic design I would be happy to help. You are a true inspiration - keep up the incredible work.

[@kletusbobby7029]

Kris, you are far ahead of me with knowledge and skill, so I suggest this cautiously. Have you considered putting an adjustable funnel type attachment at the end of the shoot, this will allow you to adjust the exact water entry angle to the bucket. This funnel attachment could also have an anti-splash back attachment that acts to keep the water in the bucket. Much as a mud guard works on the wheel of a motorcycle.

[@IndigoChild2000]

Nicely done, but in my point of view, a waterwheel isn't the best solution here. You have a drop of more than 2 meters and a descent water flow. If you installed a vortex turbine, I think you can generate 5KW on this location with this much water flow. Fish and debris can pass through easily trough the system. Also wood and water isn't the best combination as it rots away overtime even if coated with protective products.

[@1Shignog]

Same with the steel he used.

[@brunetyannick1174]

Some woods last centuries underwater, not sure they used the right one though

[@swainscheps]

Yeah I was gonna say….I think you could enjoy even more power if instead of an overshot waterwheel, you bought an extension cord… Seriously though - beautiful work. Johann Euler would be proud…

[@adriansmith827]

😮😂😂😮😂😂o😂I 😂p

[@IONACOMPUTERS]

Definitely should utilize the 2 metre drop

You need good fat in the bearings, or they wont last a year. The fat for river boat propellers should be cheap and good for the purpose

[@boutrosboutrosboutrosboutros]

Cautionary tale about really knowing the ratings of your equipment you are using. Excellent educational and fascinating video!

[@anthonyfoster7206]

Thanks Kris , great wheel mate and you ironed out the problems and overcome faults out of your control. Done by one man and not a team of design engineers in some high paid workforce in a state of the art factory. It’s a credit to you buddy massive achievement and I hope and pray you build many more of these wheels that people can purchase from you or buy the plans etc to build their own. God bless you mate you are an incredible person with true grit who sticks at it regardless of the challenges I hope you make a fortune from this prototype 🙏🏼❤️🙏🏼

[@mechniack]

Make a metal fil nose that's adjustable

[@KrisHarbour]

Yeah I think thats the plan :)

[@jerrylewis7702]

thank you

[@chrisdixonstudios]

That is a beauty! Thanks for sharing and inspiring others. Congrats to you and all the skilled men involved.

[@hotchihuahua1546]

The most efficient use of a water source for the cleanest electrical energy you can harness through human technology ! Makes me want to live by a stream or brook for many reasons , besides it’s natural beauty . ❤️

[@andymccabe6712]

Ha!....I just LOVE the way that, the second a film like this is uploaded HUNDREDS of 'water wheel experts'...whom nobody know existed(imagine that...!!!) suddenly 'out' themselves.... .....and they ALL know how to do a better job then the person who actually DID the job.....!!! SO funny....and so, so SOO predictable....!!!!! It's what keeps me coming back for more.....keep it up, guys.....!!!!!

[@theslimeylimey]

This video is right up my alley and you made a fantastic wheel. I think the buckets would benefit from a little more angle so there is a larger opening for the water to flow in without bouncing off the face of the next bucket. As others have suggested a shroud or rubber mat will certainly help a lot. I understand why you designed it this way and it makes perfect sense on paper to maximize energy extracted from each bucket but the flipside to that is if you can't get the water in and out of the buckets quick enough you are leaving energy on the table because the volume of water coming in from the trough will be greater than the maximum volume throughput of the wheel. Slow the wheel down to fill the buckets completely for maximum energy and excess water energy will be wasted, speed the wheel up to use more of the water and there isn't enough time to fill the buckets. Somewhere there is a sweet spot that I'm sure you will find with some tweaking. Can't wait for the next update!

[@malcpkim8]

I feel your frustration. You've worked so hard just to be let down by sub standard products. The amazing thing is you know why it doesn't work and have already found the solution. I will look forward to the next instalment in presenting the solution which I am sure will display your incredible passion for the work you do.
