I love how you sacrifice your home just for our entertainment. You're really an awesome creator.

I really like how you're putting up the equations and showing how to solve them. Exposure like that is super important to helping people get more used to the mathematics.

Idea for the next video, installing a pelton to harvest the power from the urinal :P But being serious, I love your new BUILD and would love to see a part 2 of this project!

What an interesting concept! Thanks for sharing your BUILD and the process you took to get there!

I love videos that are like this. stuff made here, smarter every day, you, its these channels holding me on UKposts. Thank you for making my day, keep it going.

10:00 reminding me of my granpa, he was teaching me some electric stuff when I was ~8, and sadly, he passed away a year ago. What a great memory

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

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.

I'm always happy to see a new QuintBUILDs!

Now I can feel less guilty taking a 4-hour shower. I'm producing power, mom!

the quality of the editing and the graphics are gettin better and better. awsome channel. cheers from italy!

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

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

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!

"Since metric makes everything easier". Thanks a lot !

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.

I love how you use real-world problems as an opportunity to teach your children real-world solutions and lessons. It’s the best way to spend time with your children and teach them so many different things that they can use in their future. 🤙🏽👏🏽👌🏽I try to follow this with mine.

I truly find ur show's very interesting and intriguing. What unique ideas u have, which makes it fun and entertaining. Great job man, absolute thumbs up. 👍 And yes, keep going with the shower experiment.

Thank you, thank you thank you! These videos are awesome and is exactly perfect for my learning style. Great, subject matter with fierce tenacity. Great job!

Great stuff! I'm happy I found your channel

I have a rule to like all videos where someone puts a DSO on top of a toilet.

Man your videos are just brilliant! So much fun 👍🏼

So cool that you involve your kids in the projects

Great Channel. I gotta binge watch now.

I love the videos! Great vibe!

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

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.

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

I bet your wife really enjoys projects inside the house 🤣 great video as always

Thanks for these videos.

good one! Always wanned to test this. thanks man!

Wow, this is awesome! thanks!.

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.

How am I only now finding out about this channel. Great video sir. Great engineering approaches/explanation here.

I love you channel It's so informative.

Dude, I've always wondered this. Thanks!

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.

Oh man your videos are so very underrated. I wish I had this when I was doing my renewable energy project over 10 years ago!

You make great science videos! I love physics and I love your channel.

Love these videos

very great explainations, you defenitely make them easy to understand

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

I'd definitely like to see you explore this further.

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.

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. 😊

This is awesome 👌 👏

Pretty sharp dude!

Extraordinary. Finish it and find out if there is problem or not.

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.

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.

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!

Keep fiddling with it and you’ll get it. The more energy you extract the lower the discharge pressure and/or flow will be.

Awesome video! I wonder what would happen if you optimized power generation first without a nozzle or flow restriction, and then start experimenting with how to turn it into a shower head without reducing too much of that energy. Not sure how much restriction there was though.

Your channel is awesome

I'd die happy knowing someone charged their phone with the power of ... going to see a man about a dog ;) And now that my high school sense of humor is satisfied, great work, love your videos, keep em coming!

Fantastic work!

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.

might help to have gearing done to harness it better. although i don't know how much you might lose in parasitic friction from them. might be worth a look though.

YES PLEASE!

Hello I love your videos you really have a great content. I want to ask if you tried testing the generator with a proper wind turbune controller( maybe an MPPT as for solar panels ) to be able to get the max ammount of power and charge a 12V battery with that. Maybe this will help to get the desired power. Thank you alotfor your great videos!!

I think it's cool how you can hear the wheel slow down and see the voltage drop under load

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

I love this! Did I see 3 scope probes? Wonder what it would look like with an oscilloscope. They're getting cheap nowadays, and you shouldn't need a fancy/expensive one for this project. I was also wondering if there is an optimal speed on the impeller. Perhaps faster is better You might want to take another look at the wiring of the windings. Perhaps the initial star config, along with transformers, could be the way to go. Or a gearbox. Very interesting video! I'm subscribing!

Put the generator back to star and use an xmfr to lower the voltage then rectify it to DC

Love to see a follow up :)

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.

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

Hi, This is absolutely beautiful,!!! I am working In my notes, I am very close to having enough Research, info, that can be put into a booklet. So, I will be starting on my booklet, that explains, step by step, how TO: build a house Tiny house, Campers, or anything else. And make it ( self sustained ), generating it's Own, power" to recharge a battery bank.!!

I love how you include your family lol.

Maximize the power!!! I'm so interested in

Here in Brazil we use electrical showers. Usually 5.400W or 7.200W

Loved the video! Just shooting spitballs here, but, is it possible that the frequency of the generator output is not playing well with the rectifier diodes? I know 500hz isnt crazy, but different diodes do funny things sometimes. I've used the wrong diodes from the parts pile with the expected "wrong results" before.

Pretty epic video 😎

You need bigger loads to slow it down. You have no governor on flow rate to maintain constant voltage

I laughed when you simplified the simplified Bernoulli equation. It's just so fun to see out assumptions take away all out work.

That's an awesome idea to use the water systems already in the house to get power back on

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.

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.

I also live i nthe beaverton area! Awesome channel and build. Would love to see you make your own generator/alternator for this as well. Maybe dig in more to the math needed to figure out optimal engergey at the rpm's you are at?

Can you make a video on vaccum water pump and how it can be used in commercial and residential case for fulfilling water pumping and electricity generation. THANKS

I have a rain catch that's approximately 75 feet above my barn. Could you rough out the steps I'd need to take to consider for power storage and generation? I can make the catch as large as I'd like and put multiple turbine points on it as it descends down, but I'd just like to figure out some rough calculations to see at what point the return on investment is really worth it in terms of generating power and initial cost. 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.

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.

wish you was around when i was in school, your doing a servce to these kids.

I hated Science lessons with a passion as a kid. Thank you for making Science fun, interesting and understandable 😀

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

Prehaps you shold try using an adjustable electronic load straight from the rectifier to compare the output power with different amounts of load

Incroyable cette vidéo

I love this video, I was always wondering how much waste energy was in my water pipes. I also didn’t know Portland water was gravity, I thought it was pumped!

If I learned things like this in school, I probably wouldn't have hated shop class so much.

I have a degree in mechanical engineering. I'm taking my board exam this month, I'll definitely recalculate everything. In this way, maybe it will help me master fluid mechanics and some basic electronics. However, I just finished reviewing and it's 3:20 AM in my country. I'll try it tomorrow. BTW, you have great parenting skills. I salute you as an engineer and as a father figure 🫡

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.

Awesome 😎

3:44 master of explanation !!!

eBay has hydro generators that you would be able to screw on to your shower outlet... I have seen many other videos on these things and even got some myself but I haven't used them yet! So I can't tell you how good they are but I did manage to place one against the tap to see if I can get a voltage and it did.... You can still use the original shower head too! Bonus! The output is unregulated so you will need a solution for that, I don't know how they would work if more than one is used in parallel or series? I plan to experiment with that at some point in the near future...... Would be great to see what you can come up with if you get some of these... They should be capable of 12V easy..

Might have to redo the wiring in the turnbine, i am no electrician for sure, but either thiker wires for more current and less voltage?

I want a part two

if the windmills gen, could get more volume it would work better, without it it does spin but not as fast when you load the generator ..so you need more volume.

you should proportionate all stages to deliver the optimum tuned setup , like the nozzle is proportional to the peltonwheel so it produces lower rpm to higher torque. second the regulator could be a solar PV , that will regulate almost any voltage to the intermediate buffer voltage , eg. 24 volts dc ... and thats easy to convert to a phone charger making the tailor voltage/current for the cellphone

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.
