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.

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.

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

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!

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.

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

2 жыл бұрын

@@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.

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

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.

Wow, this is awesome! thanks!.

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

I love the videos! Great vibe!

Dude, I've always wondered this. Thanks!

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.

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!

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

So cool that you involve your kids in the projects

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

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.

I love you channel It's so informative.

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

very great explainations, you defenitely make them easy to understand

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.

Love these videos

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!

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. 😊

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.

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.

Pretty sharp dude!

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.

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 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!

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

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.

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!!

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.

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.

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

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.

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.

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 🫡

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.

YES PLEASE!

You've got me hooked! I hope you find the answer.

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

Oh, I think that the 80 psi might not be from the city, but the water regulator on your house. Something I learned recently and stuck with me.

I'm baffled confused and have brain ache 😕 but I really appreciate your video thank you for sharing 😊

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

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

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

Dude... I really like your videos. I would like to make a suggestion: Make a video about heating water through magnets (Eddy Current)... Greetings from Brasil!!!

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.

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

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

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

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

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.

I want a part two

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.

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.)

I see it in extreme efficiency home. Like filling water tower from solar energy when you are at work. At taking some back when you shower after work when sun has gone. But it probably will be we go low only for going low.

Awesome 😎

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

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