I appreciate your videos and content very much. We have alot in common altho ypu do way better video production and even production of materials and tools, devices. But I really just made the comment to say thank you. I've been toying with the idea to make one of these for a long time but at the water meter location for our city water supply. I just have yet had the proper motivation. However you have proven I'm not so crazy with this idea after all.

[@privateeye2490]

Check your flow rate without the shower head (what's actually going through the hose you're using). Many showerheads have a flow limiter and what you showed on camera was ~2gpm as expected but then you removed the head for connection to the generator. Check this then adjust your math if it's different. Most homes are at least 4-5gpm. And for those that say there's no point if there's a pump somewhere, the point is to save YOU money/energy, not the utility, and you wouldn't run your shower just to charge your phone. You're already running the shower to wash so why not use the energy at the same time instead of literally flushing it down the drain? It would be better, though, if you had a generator tied into your water line just inside the supply so anytime anyone used water anywhere on the property you get to power something, maybe a small battery bank or a fan.

[@arinternationalsas]

I Didn't see you k factor designing your nozzle

[@billkillernic]

Could it be that the gap between the wheel and the 3D printed walls is so narrow that friction due to excess water now flowing down fast enough, causing the wheel to spin slower? I mean if that is the case then it is not only friction but also each "cup" on the wheel has push an x mass of water while it rotates

[@yuvalhuck5437]

Dude, you need an isolation transformer. Also isn't the three phase wiring you converted to more efficient? Like that's why 3 phase is generally used for.

First: I really love your content. Regarding improvement tips. You already got some electronic tips. So here a mechanical improvement. The pelton with two scoops per row spits half of the water to the top. Which in turn slows the turbine down while falling down because of gravity and on escape to the side :-). Maybe switching to a one scoop per row turbine fed at the high point and shooting out the water only to the bottom will increase efficiency.

[@scottadams3544]

weekend stuff, thats sounds better. if i understand your suggestion its basically rotate the device 90° So that the stream is down and splashback is up and away. Im not shure about a single cup pelton wheel improving unless its the plastic twisting stress adding a harmonic wiggle your concerned with. If so, i guess used the 3d print as a cast for puter or other metal casting pour? Somthing with more strength. Or an epoxy layer to reduce plastic deflection /cup twist. Cuz who has time for casting

[@weekendstuff]

@@scottadams3544, if you are able to rotate the complete device 90deg then no need for a single scoop pelton IMHO. The single scoop pelton was only ment to be used if the orientation of the device stays. But you are right there will be an issue with unbalanced forces. Regarding casting a metal pelton, using lost form casting, I could support with the furnace but I don't have access to a 3D printer (yet) :-). And it usually takes more than one try (for me) to get the castings right... So going with turning the device 90deg seems to be the easiest fix.

[@brendontait6968]

Go back to Y wiring and plug a solar mppt charger onto it. The MPPT will alter the current draw to make the Pelton wheel spin at a speed that will give peak efficiency.

[@DetlefAmend]

Hey Quint, some thoughts on the electric side of the project: these simple buck converters are probably not very well suited for the project. You're dealing with a heavy variing input voltage that will probably drop a lot when put under load (e.i. when your Smartfone is connected). What could wirk pretty well is a buffer - let's call it a rechargeable battery. And since you have this wide range voltage input, you can use a solar charge regulator for the charging of the battery: solar panels hve a wide voltage range and the voltage drops depending on the load. A cheap TP5100 regulator would be my choice for a test - you get these in china for pennies. With a 3.7V battery connected, you can use a small boost converter to generate 5V to charge your fone. Keep up the good work with your videos!

[@mspacone]

[@jonathanhughes380]

Current and voltage are directly proportional if the voltage doubles the current doubles if the voltage is halved the current is halved. If you plot it on a graph a change in voltage results in a linearly proportional change in current no matter what your load is assuming it stays constant.

[@deang5622]

Is that true for a diode too?

[@georgevlastos9668]

Try to use an mppt solar charge controller to convert from higher voltage to low. The mppt, constantly monitors the input voltage and tries to squeeze as much energy as possible, without pulling too much.

[@Oliviiiful]

[@oplkfdhgk]

I would be more intrested in collecting the heat from the shower water that goes down the drain. 🙂 It is so much more energy. 🙂

[@yosemiteanemone4714]

There are products that do this. It's basically a coil of copper that feeds your cold water supply to the shower, recycling the heat immediately.

[@oplkfdhgk]

@@yosemiteanemone4714 true.

[@iamdestructoman]

go back to the wye wiring and instead of using a normal 3 phase rectifier, use thyristors with an arduino to control the firing angle. Your dc out voltage is determined by the angle. Then you can the converters at the input voltage where they are most efficient. My theory here is similar to MPPT instead of PWM for solar in that I think you need to keep the velocity of the generator rotor in the sweet spot as well.

[@siryouda4985]

Hi, I am not an export, but I saw this same concept in The Great Escape with Richard and Tory on Amazon. When they overdid the flow with the wheel, they got and effect that made their wheel a lot slower.

[@krissfemmpaws1029]

Quint it is likely you are over speeding the alternator. It's likely designed for shaft speeds around the 150 to 200 Hz output range. With many alternators they are designed for a given shaft rpm range, if they are running outside of that range their efficiency drops off Another thing to look at is your bridge rectifier suitable for the frequency you are feeding it with the high RPM of the Pelton wheel? You could try a larger sized jet to flow more water to increase torque to the unit. You are playing with compromises regardless of the math.

[@JamesTsividis]

You answered my questions about the shower, rain gutters and also potential energy storage with the water stored on your roof. Thank you!

[@92MrSandmann]

Please do look into this further, it's very exciting. Keep up the good work

[@colinstamp9053]

You could try rigging up something to measure the torque from the Pelton wheel. Perhaps mount the whole unit on a pivot, with an arm to a weighing scale or something. That way you could measure the mechanical power being generated by the turbine under various speeds and loads etc. and compare it with the electrical output from the generator.

[@kenneths1585]

Great video .This is a great idea!. My suggestion would be tapping into the flow from the main water inlet into the property by fitting a turbine to convert the flow to electrical power, it would be be easier than tapping each individual water outlet to generate power as the flow rate of the incoming water supply is much greater and only one turbine would be required. Using this method power would be generated everytime a tap or faucet or appliance such as dishwasher, shower, washing machine, bath etc; is used. Using hydro power for generating electricity in the home is essential now that energy costs are spiralling.

[@adensmore100]

this is a great suggestion, you could put a larger generator on the main line to power/charge a large battery for the house to run of of and put smaller generators onto the spigots to power water heaters…the water heaters can have batteries that would heat the water instantly on demand and use the power generated from use to recharge an continuously heat the water being used…

I’d love to see if a reduction gearbox would solve the power problem by slowing down the generator and reducing the load on the water wheel to help with surging.

It is not a power problem, it's an over voltage problem. Whatever power the generator produces, he wants all of it. He doesn't have excess power, he has excess voltage.

[@robbjr7879]

I'm always happy to see a new QuintBUILDs!

[@stevenmackay3289]

Hi there: Wild guess. 1. Slow your jet stream a little bit to counter the 500hz problem. You might lose some output because of it, but it's better than your generator thrashing from being run too fast. 2. You may have some losses in the wiring. Try shortening the length a bit. 3. By using the Delta config, you may have made things harder for yourself. Use the voltage converter to limit your current prior to any other electronics that will performing the actions of charging the phone. That way your converter can take that 65v's from the Wye setup instead of the Delta setup and convert it into a higher amperage instead. (Assuming I understand correctly.) 4. How well lubed are your gears and other apparatuses? Use some silicon lube I think. Or more of it if you are already using some. Might not be quite enough to get a proper glide. 5. Stick a hybrid ultracapacitor between the converter and charging station. (I think) This way the capacitor can help smooth out the flow of power between devices by acting as a reservoir or dam of sorts. 6. Split your jet into two separate streams using a Y split before the water exits. This way you can hit both of the spoons on the impeller. Or possibly from different angles to increase output? You will definitely be splitting the psi output of the water, but by splitting that output into separate spots, you can make a more controlled spin occur, maybe. Or better yet, you could run two generators with half the psi on each; thus taking that 65v output of one and turning it into 32.5v between two instead. This can then be run to those capacitors I mentioned earlier, and create a more solid flow of power. (i think) That's about all I can think of. I am not an electrical engineer. I just read things and look at stuff and etc. I think changing the Wye to Delta was a mistake overall.

[@thomasvnl]

This is why maximum power point trackers exist. Also, not all bearings work that well in all orientations. You now have the bearing "faced down", sometimes these bearings work better facing sideways.

[@QuintBUILDs]

Agreed on both points! 👍

[@stevesether]

There is a practical use of using water pressure as backup power. It's a water pressure powered backup sump pump. It uses the venturi principle to create a partial vacuum, that can suck water out of your sump basin. Generally used as a backup pump. I'm sure it's not very efficient, and of course increases your water bill. But it's a very reliable pump that doesn't fail when the power goes out.

[@DannySullivanMusic]

[@medlevinger]

Love all of your experiments. it gives meaning and fun to all these apparently dull formulas

[@gabrielhacecosas]

If you shower without using the generator all that energy is also there and I assume it will be converted into heat, does that mean that when you shower with the generator the water comes out slightly colder? Like if the water heater is 70W less powerful?

[@de-bodgery]

1. Go back to WYE. Under load it turns easier for motors. It will probably be the same for a generator. It's probably why they wired it that way for a generator to begin with. Now get a BUCK capable of the output voltage at WYE to step down to 5v. 2. It is possible that in having your son wire it up that he got a phase backwards. For delta, a start of a phase connects to the end of the next phase. You don't do start to start or end to end in delta. In WYE, all the phase starts are usually wired together, but that could be all the ends instead. its either all starts or all ends that are wired together for WYE and you don't want starts and ends wired together. If you get these backwards, you lose a lot of generated power as the phases that are generating are fighting the ones wired backwards. 3. I doubt you have a phase short, but it's possible. If the the generator spins like it is full of honey, you either have shorted phases or reversed phases. You can simulate shorted phases by touching the phase wires together. Spin the generator by hand and you will feel that it is sluggish and stiff like it's full of some kind of very viscous substance.

[@topsecret1837]

I’m curious whether it would be possible to generate electricity through the electrostatic buildup between the ground and the clouds during a thunderstorm system. The apparatus would involve a very large kite connected to a beefy cable able to handle the enormous electrical loads, where normally a small wire would be vaporized upon spontaneous discharge. This would at the very least neutralize the charge build up that causes lightning and would prevent damage in the local area from it. It could also serve as an emergency source of electricity in case wind damage destroys power lines for a local community. Also would reduce people’s electric bills through storage of electricity and returning it back to a power company without regulations required around solar power. Obviously it’s more dangerous, but if it has to be dangerous because dumb zoning laws restrict the usage of solar panels, then so be it.

[@solarpowerelectricityandel2915]

You are having a great loss from voltage drop the amps and load from your PWM or pulse-width modulation charger. You need an MPPT charger or Maximum Power Point Tracking charger. With this you can use it at the full power point the motor is good at and power 10 or 15 phones for an example 52 volts * 1 amp is 52 watts 5 volts * 1 amp is 5 watts

[@elvindekle9835]

Your housing might be causing restriction. The water needs to clear quickly . Also , aiming your water jet closer to the inside side can capture more energy . Removing some of the cups can increase the speed . A larger diameter wheel can reduce rpm . But ! If it's power / amps you want to increase . Use the star configuration and add a transformer . Current increases by the same ratio as the voltage drop . So 60v at 1amp squeaks 2amps at 30v . Your phone uses 5 volts to charge . So 65v can be reduced to 10-12v or around 6:1 . Thus 1amp becomes around 6 . Got an old 10amp 110 to 12 volt battery charger ? Or a microwave oven transformer ?

[@AhmadAhmad-hc1hd]

Thank you for this a hugest beneficial video. 😊😊 17:55 I think the friction inside the pipes is one of the variables that decreases the power. 😊

[@Reddit-shorts]

I would try changing the bearings to ceramic or hybrid ceramic and changing the motor to a brushless drone motor or brushless rc motor and size the kv to match the output rpm of the turbine. trying two lower flow nozzles on opposing sides might help balance the power output.

[@charlespaine987]

Note Three phase power requires three rectifiers to capture energy generated. Each rectifier has losses. Delta phase configuration 3wires but does “weird buck/boost” thing. WYE configurations uses 3 or 4wires to achieve different voltage output. I am not electrical engineer just a tinker. I’m not good at math so I struggle with formulas they kind of put dampers on the fun😣

[@aarravoltics4592]

Very interesting project. I think you can rewind the generator with thicker copper wire so that the current will increase. This will also help in reducing the speed of the turbine.

[@MrWorth66]

add a gear reduction to reduce the speed at the generator. lower rpm might play nicer with the wind turbine

[@troyguererro0898]

BTW, you have great parenting skills. I salute you as an engineer and as a father figure 🫡

[@leonardkjellberg729]

I can see many possible improvements to this build. First is the large closed bearing .It will be a big energy looser with water coming out at high speed wanting to impart its energy on a wheel with low water mass. Try a smaller diameter shaft with 2 ball bearing sets spaced apart (even open ended s/s bearings are far better). Second is the generator . Getting the correct generator for the job is very important. Selecting the correct generator with windings not too thick or too thin or too big in diameter can be a bit tricky. You need the water to come out out the turbine dropping vertically if possible imparting all it's energy. Imagine a base ball player catching a ball , absorbing all that energy and then dropping the ball to the ground. This is how all these water powered generators should work to impart maximum energy. The third very important potential energy looser is the jet nozzle and pipe set up . This is a biggie and has many similarities to resistance in an electrical circuit and is poorly understood. I won't go into this rather I would like to see how you do with the first 2 ideas. Keep up with the good work!!

[@korishan]

Considering that most people pay the utility company for water supply, it'd be nice to be able to reclaim some of that cost. Instead of installing a unit at the shower head, I'd install a unit at the house feed side, that way no matter "what" is using water, there'd be some power generated and collected. Worth the cost to build and install this, meh, what ever :P

[@Kafe51]

Hi, to get maximum of the pelton turbine, the velocity of blades should be half the speed of water going from the nozzle. So you can try put there some gearbox.

[@morlan8228]

I am a bit late to the party, but I have a possible suggestion. I had to work recently with bearings in high air pressure. One of the problems I had to work around was the air pushing out the oil of the bearing. I think here could be happening something similar. As your first bearing got clocked, I think its possible that the water gets into your bearing and washes the oil out. (I am sorry for my bad english, am not native. Still hope its understandible.)

[@fyremoon]

Delta is a 3 phase, 3 wire setup. Wye or star is a 3 phase, 4 wire setup. If you used the centre tap and one of the phases, you will get a much lower voltage.

[@orowizard1369]

So, the thing to do is: put a bi-pass in the main water line passing your property (provided it is something easy to do like it would be with a large pvc pipe like my water supply has in the country) and have the electric apparatus set up there. Then you would get power from all water to your home and everyone else's down the line. (I don't understand all the electric stuff, mental block for years)

[@sabriath]

I would have separated the legs and put each one through a rectifier rated for those legs, then put it through a capacitor step bank to smooth it out. Voltage reduction to increase amperage and you're done. I think the problem might be torque related, the speed of the water is maxing out the spin rate at that arm length....wouldn't a tesla pump be more efficient as the faster the speed, the more arc length you gain in capture? Just a thought.

[@gridfreeca]

the water cover is causing water to bounce back, try making a cover that allows all water to flow away without bounce back, water and air turbulence will effect, turning water wheel 1/4 turn so water and air follows with gravity, and make a new shield like a large motorcycle fender that allows water not to bounce back and allow turbulence and gravity to assist the spinning.

[@DivergentDroid]

I've seen some pretty impressive water generator systems that use ponds and other catchments that I could reproduce here, but I'd like to see if any math will give me reasonable expectations beyond just using it for our water needs. I've thought about tripling it up to also store heat in the water since it faces the winter sun.

That’s something I’ve been wondering about for quite some time while taking a shower & glad to see someone trying to do it. I’m glad recommendations brought this up so I can Sub. To make it simpler try making a in-line turbine that connects to a garden hose first to not make a mess in bathroom. It would be nice to charge something when watering the lawn/garden & have it connected to the sprinkling system eventually or would it be better connecting to the water line coming into your house or conect it just before the water heater. It would be a good combination with Solar Panels to charge batteries. For a simpler salution have something to screw on shower head then run a wire out to the charging station that has a light to light up bathroom when power is out & has a shelf to charge devices on. It would have an on board rechargeable battery to charge 2 phones at the same time. The thing I don’t want to see is people wasting water just so they can charge their phone when power is out. We get power outages all the time & I would buy something like this. I didn’t know there was a shower head that lights up & it would be great to use when power goes out. I have a squeeze flash light & wondered if you can hook a USB port to it to charge phone. I have a Biolite stove that has a thermoelectric generator that charges my phone with wood. Have a thermoelectric generator at the gas water heater. I’ve seen thermoelectric generators you put on wood stoves. I’m all for trying to harvest energy anyway we can to be off grid. I’ll have to go back & check out your other vids.

Use a camping water cooler with a screw off top- drill a 2 inch hole at the top, and a 2 inch hole at the opposite side at the bottom- attach a 2 inch diameter hose at the top and seal it, add a 2 inch diameter PVC and plug up the end to prevent water from escaping and seal the PVC to the container, fill water all the way to the top Seal the top with a strong plastic bag to create a vacuum, put the lid back on to seal and lock the bag in place.- Drill a hole in the double wide cooler at the bottom side 2 inch hole and attach the hose to it and seal it to the cooler. The side of the cooler you attached the hose to, keep the top closed on the cooler. The other side keep open. Put the water cooler on top of the closed side of the food cooler. Fill the cooler half way, with rain water. Attach a water wheel at the top where the water will flow to produce a current the flows into the cooler. Attach the motor on the outside of the cooler to keep it dry and produce electricity! I'm a huge fan! Your videos are fun to listen to while I drive!

Try looking at the no load voltages on a scope. You can compare the waveforms to see if there is an issue. To test the core loss you could remove the stator and spin the rotor and measure the power input. Then repeat the test with the stator installed and the gen at no load and the stator installed. The difference in power will be the eddy current and hysteresis (core loss) in the stator core. This core loss will decrease some with load, but it will give you some idea. Also you may have increased copper losses due to skin effect if your frequency is much higher than the design intent.

Amazing video and creativity. This is why I love the internet!

I want a part two

[@botas4626]

Gues you need a MPPT to match the impedance of the load to the source

[@deang5622]

It's not an impedance problem. It's an over voltage problem.

[@corjapin]

i think you should upgrade the electrical stuff instead of turning down the capicity of the mechanical parts. because that is where you loose your power, by downgrading stuff and not using it`s full potential, and you get different results every time you use it.

hello quint, i'm from philippines and i am so glad to follow your works, i love physics too. keep it up...

[@trulyinfamous]

12:25 I love the absurdity of this scene. It would be very difficult to guess what you are doing without any context.

[@warchildodin]

Conservation of energy could run to the extreme if you really wanted it and build a system that utilizes some waste energy. You can't create something out of nothing but you could absolutely utilize every expenditure of energy you use. Good thinking and you give me many ideas

[@MartijndeBoer88]

To get a feeling of efficiency and debugging the problem, you could bypass all rectifying, smoothing and USB charging system and just dump all energy straight into some power resistors and measure/calculate the max power the turbine is able to produce. If that results into only about 3 Watts as well, you know you can rule out inefficiency of the electronics and focus on the turbine part.

Hi its also about sinewave switching winks, think about it, when out of phase it causes exotic ripples in the timing of a waves magnetosphere. it happens in a ripple tank using sound oscillation plates and , well THE REST WOULD JUST SPOIL IT. Power is all around us within us traveling with us always

[@rhobesauce]

"ponder hydro power" is that a sneaky orb meme reference? amazing!

[@AdricM]

yeah probably fighting back-emf gearing or going to a larger wheel. and then some losses are the bounce back of water in your housing. im sure its impacting the back of the wheel too.

[@BenMilford]

So... is it cheaper to generate electricity using the city's water pressure or buying or from your local utility? 🤔

[@EET8689]

You do a great job of combining the engineering and practicality of making something work. My personal idea is to use the incoming water supply after my water meter to turn a turbine. Just enough to be a charging station for a battery bank that is sufficient enough to run my home. The incoming water supply will be moving a lot more quantity of water consistently then just the shower. However I’m not at your level of expertise! Thanks for the video, keep up the good work!

[@alexruedi1995]

try to align the impact position of the water and the position of the magnets. both of them have a position where they can absorb most energy, they probably should match. Also, there is water stuck in the head decreasing efficiency. Just a guess.. hope it helps. Otherwise maybe try to copy a working design and start exchanging part by part

[@christianlefler5240]

I think there is a lot of wasted energy in water supply to the typical home. Would love to see an inline solution (inpipe wheel, tesla turbine, etc) to get some electricity out whenever the faucet is turned on.

[@xopexindustries]

I would test the generator outside of the shower with compressed air to verify it producing the power it is supposed to. Also would consider building the casing to hold more water around the fins with a spiral tapered outlet. The idea is for there to be consistent pressure throughout and around the fins with a clean exit for the water.

1:05 Hey... I've been in and climbed (internally) that water tower to do work on the antennas at the top! :)
