Where I am, I can more easily buy a car alternator. I imagine the reasoning with the motorcycle alternator is that in other locales like India, those are easier to come by. As a maker, I appreciate the brilliance of your design. But also I see a problem: if a car alternator is hard to come by, then so too will be the pulley.

I guess it is going to be very humid inside thay room

Is the charcoal anti-bacterial?

shit isn't holy, you lost me after you said that, first and last time viewer, plenty of other channels to watch on this topic where the people are mature.

In reply to what you said regarding alternators... a good approach if you have the time is an axial flux machine that you'd build yourself. There's a little bit of stuff in my recent videos about that.

I wish you could either be in Palestine or in one of the many refugee camps in the region, building water filters and aiding those in need. It's great to see your work on these DIY microhydro projects, though, I love seeing them and they make me hopeful for the future as we'll be facing more and more energy insecurity as the demand climbs and poverty rises.

Sir can I place an order of it?

I wonder why you dont use a PMA with a variable resistive load to measure power at the shaft. Perhaps it wouldn't be an improvement over the simple pony brake you have but it seems it might yield smoother results with easier adjustment and nothing to wear out. Perhaps the rpm is too low and such an alternator would need to be too large. I play with wind turbine rotors that way.

This is not low tech the editing is so advanced.

After years of casually researching nano-hydro, I keep returning to the conclusion that positive-displacement designs (like the archimedes screw and others) seem preferable due to significantly higher efficiency.

Hy and thanks to show your work In my opinion you are in the way to create a vortex, like Victor Schauberguer

Just found you, channel looks brillant. Subbed.

Great to get an update of what you've been up to. Looking forward to the archimedes screw fine tuning results and if possible a downloadable file of the final screw design 🙏 Awesome video - thanks for all that you do and share 🙌

Trimming the shrink wrap after install will change the balance of the wheel. ANY imbalance will be a big loss in efficiency. If you detect vibration during operation, the wheels are off balance, at least the rotating assembly is out of balance. Unfortunately, wear on the rotating parts will change the balance too.

Love your channel - great work.

That guide to spin the water was too comlex, too much surface area. If you look at the static blades on a turbine, they are relatively short in terms of the distance the water travels over them. You overdid it, and it needs to be a gradual turn from straight flow to the angle you want the water to be turning at. Plus, quite often the fluid hits the turbine straight, and it's intermediate blades that are used to adjust the fluid angle to hit the second or subsequent sets of moving blades correctly.

2:31 finger attack. I wish you included a diagram. I have no idea how this system works.

Should be a well developed formula for turbine blade shape based on speed and viscosity of fluid. Most of it is avoiding cavatation damage.

Good work, but you dont need to reinvent the wheel. The engineering and science of water flow as a energy source is well know, we've been using it for centuries. Impellers, syphons, etc are well understood and tested, use the research of others. I've been using ram pumps to lift water, the technology is 150 years old, and as good as it gets.

Amazing work!

Great work as always! Interesting to see that the Archimedes screw had the best performance, but it makes sense I suppose, and that's great info to know since the Archimedes screws are less considerably less complicated to print or fabricate than the other more complex spiral shapes. I think I can definitely print a screw of that exact size and shape out of recycled #5 PP with my TrashPrinter. There's still a lot it can't do, but it does really well with simple spiral-vase type parts like that, and I've printed turbines with similar sizes and overhangs before. I'll give it a shot once I get the trash printer going again later this summer, and I'll let you know how it goes. If you've got an STL you can send me, lmk, but otherwise I'm sure I can find one online or make one with OpenSCAD. I've got some friends up in Washington with a pond on their property that drains a massive area of steep mountains on their property, and I've been looking into ways to integrate their pond into their off-grid solar power system, as both an energy storage buffer and a way to harvest energy from the huge volume of rain moving through their property in the winter, when they get basically no solar. I would love to test out one of these turbines up there. I figure we can build one to start and get some data on its performance, and if our results are promising, we can calculate how many more we would need to match the natural seasonal flux of the pond, and then build an array of them. Thanks for collecting and sharing this data!

I didn't see the Basu/shist disk in there. You should try that one, it's shown high efficiency in moving water. Probably means it would be decent as a turbine too.

The logarithmic spiral types are intended to throw water out to the side, if they're constrained within a tube then all you're doing is increasing the pressure and friction.

Wow good to see the end results of those variations of 3D printed Turbines, You are always welcome to Nepal and Kathmandu University for more Research and Hope to be your help again in the future.

Excellent job! I am a bit surprised that the flow guide didn't help. It should have increased the RPMs of the spindle but probably reduced the torque, Did the flow guide made the tank to empty slower? Could it be the case that cumulative energy is higher while instant power suffers?

After problems with You Tube channel, in the past , I thought that you've given up filming and fell off the radar (turns out that you've gone above the radar -I mean Nepal...). Btw , I was under impression that in Nepal wind power would be more interesting , but I could be wrong.... Now , since you are back (on YT , I mean) , I have some questions , regarding the turbines you've built (in the past and recently) . Since you utilized height difference of about 4 meters and more , between intake and outlet of the pipe , would it be possible and/or beneficial (in terms of energy production) to put more than one turbine along the length of the pipe , using some "T" fittings at angle of 45° , let say , one meter apart ? Second question: would the "screw" design benefit from making the screw longer , using the more mass of the water (more available torque ?) and how we can determine the best pitch of the screw and whether is uniform pitch better (more efficient) , or ever changing one (for a particular length of screw and water velocity). Third one : did you ever compared , or calculated , what would produce more power (with exact same generator used) - the siphon turbine version , or (for an example) pressure powered Turgo turbine (given the same intake height nad same diameter of pipe , of course , with injector at the end for a Turgo turbine version) ? All the best !

Have you ever tried 3D printing a adjustable penstock gate that would sit just above the turbine blades? It looks like the circular radio active symbol but there's two that overlap and depending on how much you align the holes in the top plate with the bottom would control the flow rate and head pressure.

Nice work, bro 😊)

thats literally the fastest ive ever subscribed to someone

👍

Cool, looks like about enough power to charge a cell phone, maybe 20w continuous? FYI, don't believe the $ numbers people, this is cheap, but a hoverboard motor even used, normally is at least $40.

can you send me that 3d print

Very relaxing and informative and motivational - all in 1!😊

Wher9the testing & results?

Add a gear rasio more power

Great vid. In the future you should consider using the closed captioning for instruction and other data. And measurement data, where/when applicable should be the dominent thing in the screenshot.

Nice! I have a geo cooler for my dense urban greenhouse of 42 sq/ft. Car alarm floor that is my version of urban LOL!

I was wondering about using the power of siphon to pull water through a dyanmo at the top, instead of the bottom. Low budget, low power dyanmo that screws onto the hose at the top of the 300ft of siphoning hose.

cant see in the hole

thanks a lot, please any one explain how this project suckin water? (theory sucking from one side water)

Thanks for sharing!

I wish you guys has this for sale you would had buy it.

Job idea

you want the hot return to enter at the bottom for a more even heat.

How much maintenance does this project need?

Allora non sono l'unico che usa i taglieri in teflon o in legno per costruire altre cose. Una volta ho preso un pezzo del tagliere in teflon di mia moglie per fare uno scorrimento ad una catena di una moto da cross, un altro pezzo per modificare il bastone da passeggio di mia nonna e così via mia moglie ha dovuto comprare un'altro tagliere

The animation is at least as impressive as the design and build! Thanks for sharing.
