In this video I make modifications to the design in order to fit a induction motor used as a generator. I then go over to johns to get the capacitance right and then back to the wheel to get everything up and running.

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
@henkkalter3892 6 месяцев назад
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
@allanallansson9532 6 месяцев назад
@@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.

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. 👍

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 RU-vid by far.

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.

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.

Hi Kris, I'm no engineer. I can't do the math let alone remember all the formulae. I was blessed to be able to work as a technician (the hands on guy or grunt) with many many engineers from all over the world at GM, so I got a chance to converse with them about everything from the theory of relativity to lunch for nearly 40yrs. I'd like to try and add my hairbrained idea if you wouldn't mind. My understanding of how an inside component of an automobile transmission torque converter; the "stator" works is: A row of small stationary "foils" attached to the casing of an axial-flow turbine, positioned between the rotors, that redirect the splashed fluid back into the turbine to add torque. I am referring to the splashing of water that appears to exit over the bucket and freefall through the air offering no further energy after it has splashed. By redirecting the splash inside the automatic transmission torque converter the torque is multiplied so greatly that I don't believe there is an automatic transmission in the world that doesn't incorporate it. My own vision was/ is a shield that is designed/ sized to redirect the splash back into the buckets, sort of the way the housing fits around a turbo charger. Fun to watch you and thank you for endeavoring to persevere seeking solutions to all the issues. Merry Christmas to you Kris. ben/ michigan

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 got it working well now. For those saying that 1-1,5kW is not much, when the system is able to generate 20kWh a day during winter time this actually is enough to run a 7-8kW heat pump for most of the time entirely from water power alone. and it will do it for 24/7 during winter time when heating is needed but Solar doesn't do much. I use a 7kW heat pump, and with an outside temperature of 0°C it uses 800w on average to keep my house warm, it's just when heating up indoor when it uses more power for a couple of hours. So you will heat your house without importing from the grid, which is what you mostly will do when using solar.
@jonclement
@jonclement 6 месяцев назад
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.

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.

@YodaWhat
@YodaWhat 5 месяцев назад
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

Always a pleasure watching you turn theory into practice. I'm looking at the conduit that connects the wheel to the controllers and can't help but wonder what is above it? Any concerning "widow makers" which could fall on that as it is in quite a precarious position to withstand any such occurrence.

I'd love to see some near high-speed shots of the bucket filling/splashing on various load conditions. I wonder wether some kind of baffle inside the buckets could improve performance. Also i dont think using more water is wasting it when it is available. The energy will be dissipated regardless of going over your wheel or just into heat and noise through the bypass. On thing regarding the rod: you added a lot of security systems electronically, big installations usually use intended breaking points as mechanical fail safe. In your case undersizing the mounting screws for the anchor for your tightning rods could achieve that. For example should the engine/gearbox seize up, the resulting torque would compress/extend the rod and its anchor screws then can shear off to release the belt and let the wheel spin free until your govenor stops the water supply.

hello, I love the amazing work you have done. Thank you for sharing it with us. I would be very curious how much more power the wheel would produce with a piece of rubber containing the splashing.

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.

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.

@@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. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-dLC3ZWf7WG0.html

@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.

Love this Kris! Just an idea, if you're going to install a speed monitor and an actuator, why not have a sleuce controller that can cadjust the flow based on either the wheel speed, or the wattage it's producing? You could then remotely tweak the system in terms of the flow etc to always keep it in the sweetspot. Not sure how you would design it, but i'm sure you'd be able to. Always look forward to your videos, never disappointed!

Hi, I was going to say the same thing. If you go to the trouble to design an overspeed shutdown, why not go the rest of the way and make it realtime adjusting speed controller.

I would actually say there is a beneficial environmental impact from the added waterway. More riparian, more habitat for aquatics, more room for floods to disperse. If you don't have beavers, having humans rediverting water intelligently is the next best thing. Not to mention that you are using it to produce power so you aren't leaching off the carbon fueled power grid as much. Also, I really enjoy your content. The knowledge you've aquired and skills you've built are quite impressive. And while these comments from impressed viewers could easily overinflate your ego, you don't seem to let it. Good on ya, mate.

I wonder if a big guard along the front of the wheel would reduce the splashing (or kick it back into the buckets).
@ehombane
@ehombane 6 месяцев назад
Better a wider wheel. There is plenty room for double size. With double capacity, all the flow could be used without splashing. Obviously with the same size of the feed. Or maybe only 50 percent wider. The guard will be useless. till water fall back, the bucket is gone down. The key word is capacity.
