Powering An Old Mill 1.5 Kw Lake District Overshot Waterwheel Project Part 4

[@rs2024-s4u]

Being an EE retired since 2011 I am impressed with your grasp of the mechanical and electrical specifications and skills needed to correctly design and build a one off generating system to a specified output. Great Job. Ray Stormont

[@slyknowledged]

Maybe you can answer me then. It appears to me that there is plenty of force from the water to turn a different gear ratio for a higher ratio towards the motor. Could this be done to change the 1500-1600 produced, into 1800ish? What fails in this scenario? I'm no sparky, I play with bricks, blocks, and stones!

[@henkkalter3892]

I am also a retired EE about 10 years ago. I don't believe a gearbox could produce more output, as Kris has actually already shown by using more water. Because the resistance is too great and the wheel slows down so much that the water fills the buckets too quickly. The only thing you could do is make the buckets wider. But that means you're actually starting from scratch again.

[@allanallansson9532]

@@slyknowledged The limitations most probably are in the water wheel and that cannot be changed by gearing. As Chris shows the buckets are filling up and peaking at 1500-1600 W. Changing the rpm with other gear ratios should not make much of a difference there, just risk increasing the splashing and losses.

[@you-know-who.]

​@@slyknowledged or give it a higher resistive load with more capacitor

[@rs2024-s4u]

Excelant points pre-loading the buckets would allow for slightly more water and cut down on splashing and could be easily returned to original if benifits were not proved as buckets are not changed just more completly filled.@@henkkalter3892

[@Druls8]

The way I saw micro hydro turbines do their shutoff/deflector setups is they use a weighted flap retained by an electromagnet. When there is an emergency the power to the magnet gets cut and the deflector plate drops in place. Similar could be done here. No moving parts for the actuaction itself, as long as the eights are sized propperly. Anyway amazing job, the survey was really close aswell! Enjoyed watching this series.

A 2.2Kw asynchronous motor can provide 2.6Kw used as a generator. (5.87A*3*230V*cos fi 0.64= 2592W) In the old days here in Denmark we made wind turbines with asynchronous motors as generators. When the speed of the motor reached above synchronous rpm, a contactor connected directly to the mains. In the event of a mains failure, the motor loses magnetisation and runs freely. Nicely done project. Comment from a Danish electrical technician. 👍

[@NigelMarston]

I absolutely love this project and I'm so jealous of the owner. I invested in a load of solar panels and batteries this year which will save me a fortune over the course of the year even though they are pretty useless this time of year - I have over 9KW peak but they produce next to nothing in this grimy-greyness. To supplement them, I've been watching your wind turbine videos, and I'm experimenting with the motors from an old "hover board" but really I'd much rather have a water wheel for the consistency and sheer power you can get from one. Overall, the peak values that solar can produce do not compare to having something generating 24x7. The wheel you've built is the best I've seen on KZbin by far.

[@ilenastarbreeze4978]

Exactly this for me. When i was looking at a house ti buy i was wanting to have water like this. But where we are we get lots of wind so im probably gonna go that route for power gen to augment the solar. Cuzz i dont wana rely on sunnt days though we tend to get a lot of those around here too

[@simplyr62]

[@jonclement]

Here's a thought: since the water picks up speed down the ramp it tends to load into the bucket at a high velocity. I wonder if it's possible to SLOW the water just before it falls into the wheel buckets (to reduce splash)? A mini dam who's 6 inch depth would absorb some water turbulence prior to dumping down into the bucket (or even a couple 1/4" bumps near the end of the ramp). Especially since your power is from water weight and not water velocity. Just a thought! Great project.

[@stuartbazeley-vk6sd]

Some great points there but water inertia increases derived power

[@kleeblattsamuel]

The splashes are caused by the buckets, In my system, i bring the water from the other side of the wheel bu I still have some 20% losses

[@maarten_notjustagrip]

Congratulations on a major milestone Kris! How about a flow divider of some sort, controlled by your sensors, to maintain the wheel at the necessary speed/flow/load by directing more or less to the wheel. Think boat rudder and autopilot actuator. I think the splashing could be attributed to the "Pelton Effect" happening in the bucket, especially if the wheel is being electrically braked but the flow volume is high. There will be that sweet spot where the wheel speed and the flow match. Crack on Mate. Ex Heli Engineer, 30 years in Film. Enjoying following the progress. Thank you

You have created a beautiful work of practical art. You have also demonstrated the sheer amount of intricate work and materials and planning needed for an open falling water system.

Fantastic job, Kris, and a very engaging video as always. I doubt you'll see this comment as there are so many, but my only criticism of your system is your use of an AC-to-DC power supply to power a low-voltage contactor for the load dump. I (an EE) would've used a contactor with a coil that could be powered directly from the mains, eliminating the AC-to-DC power supply and increasing the reliability. Sorry if I've misunderstood your system but I think that's how it works.

[@chox2001]

The water chute to the wheel could be enclosed ,slightly above the water to funnel the water to the buckets more efficiently (less splashing).

[@Henning_S.]

Yes that should work, but that enclosed funnel needs a hinged "roof" so it can get pushed up if there are any larger objects in the water which doesn't fit into the buckets, for example sticks or an empty bottle or maybe even a soccer ball. If the enclosure is completely fixed such objects would jam between the enclosure and the wheel. With a hinged top plate, it can swing up and let the objects pass through.

That's really cool well done! Perhaps to improve the laminar flow of the water, perhaps fill the trough with pvc pipes- if it works with straws, I'm assuming it could work with pipes- it may help with the splashing- that or fins at the end, if it works on propellers, I could see it working with water- who knows, could get an extra few watts out of the system

Very impressive Kris must admit even though I only get intermitent high flow on the ditches on my farm since watching you I'm concidering a small hydro system to mix with solar and wind One thing that crossed my mind watching the splash loss on full flow do you think a curved shield fixed to the frame round the top third of the wheel just after the shoot would force it back in and improve the peak output by keeping the buckets full Would be an easy and fairly cheap experiment

[@klaasvanmanen8214]

Congratulations! I've been thinking about the amount of splashing you have. It might be useful in future designs to extend the bottom of the buckets upward/outward a bit because you loose most water over that edge. Another point of interest might be the shoot. As there is a bend quite close to the end, you might be able to create some less turbulent flow by putting some parallel thin metal slats in the section between the bend and the end, so as to guide the flow to become parallel (or laminar). I hope your next video will be out soon and show us the progress you made on the barn. I guess you may have fitted a roof on top of it by now.

[@MrRain-hk4zi]

Great job Kris. Enjoying your series. I would like to build something like this for my off grid place so I'm studying.

[@EdOfTheNorth]

Well done. The shape of the buckets can greatly affect the amount of splash as well as the actual torque at the wheel axle you get from any specific diameter wheel. Just something to look into for any future builds. Cupped buckets are far more powerful. Merry Christmas to you and yours.

[@randybass8842]

With a water wheel, it is the mass of the water pulled by gravity that produces the torque that is converted to electrical energy. The straight sides of the buckets maximize the volume, and hence the mass of water in each bucket. Cupping the buckets would reduce the volume in each bucket, reducing the mass, torque, and subsequent energy produced. Cupping is more appropriate for turbine generators where the driving force comes from the directed water jet, as with Kris' home system. The one thing I could suggest, for a water wheel is to increase the number of buckets, each one then with a smaller volume. This might help with splashing at the higher flow rates, but could also make it worse. Testing would be needed. I'm speaking of a future project, of course. This one is excellent, and I see no need to change anything. Well done, Kris.

[@EdOfTheNorth]

@@randybass8842 I built my 8 foot x 2 foot steel water wheel 35 years ago and though it is no longer running I did learn a lot from building it. You cannot add or lessen volume in a fixed space by cupping or not cupping the buckets, you can only direct water flow inside the bucket itself by cupping, exactly as you would observe in a pelton wheel. The key to cupping the buckets is to keep as much water as possible in each bucket over the course of its downward rotation between 12 and 6 o'clock. Cupping actually allows for the inflow of water to occur at 11 o'clock instead of at 12:30 o'clock, adding more volume of water being held while slowing the wheel and reducing splashing. This is what my water wheel looks like with some technical information. kzbin.info/www/bejne/mn2mZI2Nm5yKfZI

[@randybass8842]

@EdOfTheNorth , perhaps I misunderstood your definition of cupping. I was thinking of a rounded bottom, like a cup. Are you referring to a curvature from the top outer rim to the bottom of the bucket? I'm not a water wheel expert, and was speaking from a background in physics.

[@Perma-Gard]

Ive been planning my future dream home in a journal at the moment and was looking for a bunch of different ways to sustaibably power my home so I can live off the land, and this little series is PERFECT! it's inspiring and given me the desire for hydroponics on my property❤️❤️

[@YodaWhat]

Very impressive work, Kris, both the design and the fabrication! 😃 Your restraint in keeping from "turning the air blue" over the Chineseium lies 👿 is also quite impressive. I am curious to know how much the generator frequency varies between minimum water flow and full flow, because changes in the frequency may affect the ideal sizing of the 3 capacitors that help turn the motor into a generator. To optimize the microfarads of those caps, it might be useful to insert a 3-phase Variac between the caps and the motor. Then you can, in effect, smoothly vary the capacitance to find the _ideal sweet spot_ of efficiency. Then, based on the Variac results the exact right size of caps can be installed for an efficiency compromise, or _one or more sets_ of extra caps can be selected to vary the effective capacitance in steps, through one or more sets of relays. 🤔 I am also curious about airflow to the fan of the _motor acting as generator,_ since the new cover seems to be very close-fitting over that cooling fan end. Shall we assume that the cover is solid there, with only a tiny gap to let air reach the fan? Or is the cover open there, causing a risk of some water splashing onto the fan of the motor? (I can see that water will not reach the interior of the motor, since the type you chose is TEFC: Totally Enclosed, Fan Cooled) @Kris Harbour Natural Building
