How to use a motorbike alternator to generate electricity from wind, water, steam, Tesla, or most other kinds of turbines.
Bike alts are about the easiest option to find in various parts of the world, but as they have no built in bearing they need to be mounted in order to spin.
I'll be showing you how to use a bicycle wheel hub for this purpose.
Check my channel for guides and tutorials on turbine designs that this can be used with.

You explain really well, it’s great when things fit together like that, as if they were meant to be repurposed that way.
Mantul
Mechanics are amazing in this way.
Love it, this is one of the best DIY genes I’ve seen, must get myself a Bike Alternator now.
Like your videos and your T-shirt. Not many people will get it but a Bluenoser will!! Hello from Nova Scotia.
Excellent that a bike wheel hub/spindle fits together with the motorbike alternator, don’t you just love it when projects just fall together like an easy jig saw puzzle, as if they were meant to be. ✌🏽🌎
You are such a GOOD profesor, lots a pedagógic skills, !congratulations!
FROM México!
This VERY LAST days I was drawing & making figures about DOING THIS WORK with bike hubs & wheels,
Came to various conclusions, one was to use motor bike, I AM so glad to see THIS mounting
clear, down to earth explanations...Thanks. Love it !
Glad it was helpful.
I just found your vid!!
Thank you so much. I cant believe how easy that was, and so many differant things you can use to make it work..
👍👍👍👍👍😇😇
Glad it was helpful.
Everybody doing tech videos should be as good as this. Perfect ballance of "do this" footage, and solid description. Best of all, none of the b.s. blather.
100% bro. Great idea, I gotta try this. I wonder if the generator off a Goldwing makes more power?
I know you’re shooting for low tech but some 3d printed collets could take all the guess work out of maintaining concentricity along the shaft. I’m really glad I found your system, it makes so much sense!
How do you mean?
@@OpenSourceLowTech it looks like there is a little bit of fiddling to keep the parts aligned along the axis, if you made a tapered collet the taper could handle alignment while the collet grips the other part evenly. If you’d prefer to avoid 3D printing parts you might be able to find collets from something readily available. Lots of machinining equipment use collets for concentricity but I’d bet there is another less expensive source.
You are the best science teacher I've had. Thank you.
Excellent video with a detailed presentation of how to proceed!
I can easily envision a small scale power system that utilizes solar PV, wind turbine and water turbine to continuously generate power for a lithium ion battery bank.
Strategy: capture as much free energy as you can whenever it is available, charge your battery bank and then use your stored power supply wisely until the next recharge period.
This is essentially exactly the approach with renewable energy in general; harvest abundance when you have it (sunny days, windy days, rainy months etc) and then store as much as possible to get you through the rest of the time.
@@OpenSourceLowTech hey buddy, im kinda new to this "free energy", IF i find a way to keep multiple water+wind turbine running 24/7, can i connect them to a 10k -15k inverter, make a water heater dump and light my house 24/7 ? without having batteries into the system ?
because my country has no power grid, only mafia generators that are toooo damn expensive and barely give u 10 hours /24h electricity PS: Yep , its Beirut .
@@philipfeghaly4210 I am interested in options for not having to have batteries, but they are pretty useful. Even just a couple old car/truck ones to add capacitance into the system. It may be possible with hydro, since it's very stable and reliable (provided the water supply), but there'd be pretty much no chance with wind, as it's perpetually all over the place.
You'd presumably want a lot of supply.
@@OpenSourceLowTech if you add more aligned fans and a couple of alternators on the same axe , can u get lets say 3 times more Watts ? im trying to do it without batteirs since in my country , they sell you the indian fake parts for twice the price of the premium US, europe prices/quality

Cool man I've got one laying around my garage will give it a try. thanks for sharing.
Hey! Just pulled one of these off an old bike I found. If you dont have one of those flat wrenches for the cone nut, I found that it worked to bend a 2" framing nail into a horseshoe, pass it over one side of the cone nut into the flat grooves and grip it with some channel locks. Wrench or other grips on the second nut and it comes right off. The nail fits those groove sizes just the same and no special guy needed. 👍
That's actually a very good idea, thanks.

Wonderful; most helpful. Great commentary
Why didn't I know this channel all these while. I will appreciate to see the results of the project, which wires to connect for charging batteries, and the voltages system (12, 24 or 48volts).
Greetings from Nigeria
Great idea, very good indeed. But if you want to minimize friction losses use a biciycle chain instead of a rubber belt because it produces huge drag. And the main problem is that with poor wind the belt is too heavy to start moving.
Chain is also definitely an option, and pretty easy to implement considering it's a bike wheel hub it's mounted to. But the issue is gearing, in that to get more than 5:2 from available sprocket sets you'd need to go multi stage, which can be a bit of a faff and introduce further losses.
Using a bicycle wheel as the large pulley with a belt can give up to 12:1 in a single stage, tho it does have the other issues you state.
This is all mostly an issue for wind turbines, hydro is usually higher revving and can often be gotten away with direct drive.

@@OpenSourceLowTech Instead of geatting enough wind by changing of Tweaking feat size, can i be Succesfull according to your experience?
Sorry it's wrong for my english
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.
Car alts have a couple strengths; mainly high max output power and amperage, availability, and often having charge control built in.
But the main drawbacks are they're pretty low on volts per rpm (so you have to spin them fast), not usually self energising, and low efficiency over all.
Love ur vids. Very informative
Awesome Video
@OpenSourceLowTech can you please make a video on the different types of motors/alternators that would be best recycled. Motorbikes, scooters, washers/dryers etc. And how to wire them if needed for best results. Also if you were to purchase a replacement generator head already made for producing electricity(ex: for a wind turbine or gas generator), which would it be? Thanks.
Thanx 4 sharing ❤️

If you use a Hoverboard magnetic hub, fits perfect,I have a 18 coil Stater from a 500cc 3 phase makes a lot of power.
Yeah hoverboard wheels are usually pretty good for these kinds of applications and I use them quite a bit.

i like the idea,i have lots of stuff like these parts you have.good ideas.good job,many options for sure.wonder if you attached some more magnets on outside of magneto to increase power.of coarse keeping it balanced.good video.
Do you have specifics on what one you have because I am unable to find them only parts
They're all kind of different. Generally best to go for the biggest slowest bike you can find, as it should do better volts per rpm and power overall.
But more or less any stator and rotor which match should do good enough a job. Try auto wreckers and pull them off an old bike.
Brilliant ideas - great video with the detail well explained. Thank you for your generosity in open sourcing all your research.

Hey bro you just got a new sub cool... Your accent sounds kiwi?? Are you nz based would love to check out your work
From there originally but currently in Europe, mostly Scotland.
How is the simplest way to change to DC to charge batteries? any way it can be done without making a bridge rectifier? Cos I’m having difficulties with that, re getting the parts etc, I’m a qualified fabricator, but not good with electronics. I want to build a VAWT from a Cordless Drill( I have the Drill and Turbine materials), but can’t do it cos I don’t know what size/capacity Blocking Diode I need?
Depending where you're based you can usually get a three phase bridge rectifier on eBay or similar for about $5-10. They're usually rated to something like 50A x 1000V, which is definitely enough for more or less anything.
I never bothered to make my own out of some diodes, but that's also an option.
@@OpenSourceLowTech Thanks for relying & info, could you tell me what size/capacity Blocking Diode I would need for my above VAWT that is a battery powered hand drill motor( 7-10v ?), to 12v batteries?
Will run the fereage and washing machine what watt will produce
Most bike alts should be good for about 300W continuous or so, but they vary.
I've yet to burn one out.
Which is best/most efficient? The motobike alternator or the hoverboard wheel. I have a shingdengen 020AA regulator/rectifier and want to charge 100Ah wet lead acid.
HB wheels are better in most ways. Power rating is more or less the same, but the wheels do about triple the volts per rev, and are a bit more hard wearing and weather sealed. Often cheaper too, if you get an old board second hand for $20-30.
But that's only in countries where they're generally available, while bike alts are literally everywhere.
Thank you. I have a lot of HB wheels.
I am going to use it with a 50cc honda clone (gx50) as a portable batterycharger for campervans instead of a large 2000w 230v generator with a batterycharger connected to it.

Shout out to Buck65, haven't listened in a log time!
Good evening - respect for your open source lowtech knowledge sharing with us . My question- waterturbine motorbike alternator - you told us output aproximatly 100 ,200 ,400 watt, earlier announced Hoverbike e engine will produce 400--500 watt- why we should using motobike alternator? price ? best regards and thank you!
I'd use a hoverboard wheel if you can get one, it'll do a generally somewhat better job.
But they're usually only available in certain places, whereas motorbike alternators are literally everywhere.
Tanks YES you are right, WhatsApp the difference in offeriert 100,200 original 400 Watts ? Best regards Thanks for sharing:-)
Not sure I understand..
I recently built a small dam and look forward to building a turbine using this strategy. My creek/dam is rather low flow compared to most and dries up seasonally. Is there a certain minimum amount of waterflow that will be required to make this work? I don't require any particular amount of power, enough to charge a phone or light a bulb would satisfy me as a beginner.
How low the flow in wet season, and what's the meters drop?
@@OpenSourceLowTech The drop is maybe two meters at this point, I might be able to get it up to three meters by spring/wet season.
Edit: If more of a drop is needed, I might be able to construct something else uphill but I'm hoping to use the dam I already made.
would it be good to attach the outlet of the stator to a motorbike current rectifier?
Yeah that should work fairly well as a low key kind of approach. Reg should manage the battery ok, but doesn't have load diversion so will just turn itself off and let the turbine free spin once the battery is charged, which may not be ideal.
I'm going to be experimenting with options for load diversion which don't necessarily require a full charge controller, will see how that turns out.
@@OpenSourceLowTech thanks for the reply. I'm thinking about building a small water turbine in a small creek that goes by my cabin. And I was thinking about connecting it straight to an inverter. Is there any way to make something cheap and similar to what I'm planning? Thanks again. Your channel is amazing!
@@OpenSourceLowTech Daniel - if you want some electronic input for a load controller please advise. I'm reasonably good at minimal cost basic components designs. Russell McMahon (Rus El)
@@rabbitempire5114 What's your water supply like in terms of drop and flow, and how much power you hoping for?
Going straight to an inverter may be possible, I've limited experience in that side of things. You might want to ask on this group: facebook.com/groups/windturbinemakers
Russel you'll also know more than me about this stuff.
@@OpenSourceLowTech well I should calculate the flow, but I can get it to 3 or a bit more meters. I'm planing to intube the water into a 110mm pvc pipe and then make the water fall vertically as you do in your hoverboard generators. But I don't know about the flow... I can take pictures of the stream of water. But I don't know how to send them to you.
how many volts we can get from that alternator???
They vary, but can be up to about 18VDC (rectified) / krpm
Would a motorcycle hub work, or is it not the right size for the motocycle rotor and stater to fit into, as the bicycle one does?
No, they're much bigger, and a very different shape.
Bit harder to get too.
i think the best motorcycle alternators are the motorcycles with very low rpm engines this way you should get best power production also if you find they is not a long enogth axle threaded bar can be used
Yeah I've been wanting to get my hands on a quad bike alt, but they're surprisingly rare in western countries and pretty much non existent anywhere else.
Tuktuks might be a better bet tho.
@@OpenSourceLowTech tuktuk c90 c50 any that kind
any engine with fixed timing will no doubt be a low rpm engine
I don't know a huge amount about motorbikes and engines, which are likely to be fixed timing?
@@OpenSourceLowTech i think the cdi ignition pritty much change that hole idea i would say small 4 stroke engine are low rpm due to the valves where as 2 strokes less moving parts are higher rpm
Hello. Greetings from New Zealand. I have a broken moped. I think the charging circuit is okay. And an old bike. My question is can you make this run DC or is it AC only? :) Awesome video. Thank you.
They'll all put out some kind of AC, but bridge rectifiers are only a couple bucks, or can make one out of some diodes.
could you not rewire alternator for more power?
Rewiring is an option, but is only useful if you need to shift the volts amps ratio, which can mean more power overall if it ends up a better match for your revs and torque profile coming off the turbine.
since watching your graverty water wheel idea i been looking about for cheap segways to steal the motors
Depending where you are you should be able to get a whole hoverboard second hand from the local classifieds or similar for about $20-30.
@@OpenSourceLowTech yeah they are quite a few easy to get hold of just not been able to with lockdown and things
Is their any benefit to using a car alternator? More power etc..
More power and doesn't need mounting, but a lot less efficient and needs pretty high revs to do any useful voltage. Also pretty heavy.
Does anyone have recommendations on ways/ places to get a motorbike alternator. Is this something I will need to get a old motorbike and strip for parts or go look around at a junk yard? Looked at new ones and seemed a little high on the price.
Yeah wreckers or an old bike is usually best. Can get them second hand online, but can cost a bit.
@OpenSourceLowTech which motor bike alternator you have in your video using??
Don't know the model. They're usually broadly similar and should work with this process.
@@OpenSourceLowTech thank you for replying back I been having very hard time finding the right motor generator for my model to run for a small housing inside five propeller that I will blow air on it but I like to know is it easy to rotate by hand? I would like to get one and connected to propeller shaft by flexible coupling Im looking for at least 14 volts and 200 watts output. I would like to show you the housing if you have an email please.
They usually cog a bit, but shouldn't give problematic amounts of resistance.
Should do 14VDC (rectified) at about 500 rpm or so, depending.
Usually good for at least 300-400W, depending.

@@OpenSourceLowTech Thanks I will do that please note the size of the housing is 5.25" x 5.25"
@@OpenSourceLowTech check your email pls.
Are they better than the hoverboard wheels
In terms of efficiency, max power, and volts per rev; no, but not off by huge margins.
In terms of ease to mount and work with; sort of similar.
In terms of availability; way easier to find in most parts of the world.
Thanks
how about taking the case and splitting it and using as much of the case with crank cut off and welded to a sprocket or /front cog from motorbike or belt drive etc?
Maybe? I haven't really had a good look at the usual casings to see what would be required to do so, but it'd have to be a fairly decent chunk of the thing.
Excelent Daniel! I Will try a wind turbine for that.. what vawt size could be minimal? Sorry my english..
Depends on variables. How much wind do you have and how much power you need?
Hello Daniel, thank you so much for the tips, are so interesting!
I have a question for you:
Is it possible to connect it to the mppt of the solar panels to recharge the battery in the cloudy days or in the night time?
Thank you :)
Wind and hydro usually make pretty compliments to solar, but a solar MPPT controller won't work well with wind, given its significant and constant fluctuations of voltage and amperage. MPPT wind controllers do exist, but are more expensive and complex.
I've not yet tried plugging a hydro turbine into a solar MPPT, but I think it should maybe do a decent job given the stability of the output.
@@OpenSourceLowTech thank you for answering! I was thinking... Maybe I just have to put a limiter to avoid the battery overcharing
What about the alt frequency produced??? 60 Hz?
Coil Wire Thikness
Where is the rectifier?
How much WILL output at 160 rom with load?
Hz will depend on rpms, wire seems usually rated for about 10A on the low voltage coils and quite a bit lower than that on the high.
No bridge rectifier built in, but easy enough to add one.
Output depends on a handful of factors.
What is the best way to mount the alternator axially to your DIY water turbine?
Good question and not currently specifically sure, as still using the hoverboard wheels by default and this is the next option to trial.
Essentially it just needs to physically attach such that the water weight hangs off the alternator bearings, and the shaft doesn't unwind out of whatever thread is being used.
It does tho, like with the wingnut assembly on the current configuration with the HB wheel, need to involve a kind of universal joint type functionality, so that any misalignment between the axes of the alternator and drive shaft can be accommodated without vibration or flexing.
So needs to be able to wiggle a little, basically.
@@OpenSourceLowTech Thank you for the quick reply. Is the hoverboard alternator a more efficient alternative to the motorcycle alternator? If so, I will simply go this route. The reason I am asking is because I recently relocated from the US to the Philippines and am looking for an affordable alternative source of electrical power for the villagers here. There are nearby elevated irrigation canals that could possibly be utilized and your solution offers the most economical option that I have seen.
Motorbike alts are fairly reasonable options, but the hoverboard wheels are more efficient, powerful, easy to work with, hard wearing, and weather proof. Often also cheaper, but the one key advantage of the bike alt is that you should be able to get it anywhere in the world, whereas the wheel is more just where there's people rich enough to purchase such items.
I have no idea what the Philippines has available, you may be able to find one somewhere.
i was hoping to do something similer but have the fly wheel on the inner side to spin with the sprocket casset so a water wheel could run bycicle sprocket and chain and give away to change gear to find the better voltage range maybe speed
Inner side?
@@OpenSourceLowTech yeah the fly wheel on the hub rather then axle as the hub would spin as normal for the bycicles gears to work
@@OpenSourceLowTech never mind i just got to the bench test equip had not thoght of using the rim as a larger pully wheel
Ah I getcha. I actually did it that way the first time for that reason. Mounting the stator on the hub was easy enough, but only way I could usefully mount the rotor on the axle was getting someone to lathe out a housing for the encapsulated bike wheel bearings, which ended up working well enough, but a lot more hassle.
As I say here, there are at least two viable ways of connecting the rotor to the sprocket set.
@@OpenSourceLowTech yeah i was commenting befor i had scene the hole video annoying i know but i have to get ideas down as i have them or i forget may start using notepad for the questions and watch video till the end then ask them i like the wheel and the segway motor the same could be done with the motorcycle one you have done and think that prob the best i was thinking of maybe using bycicle wheel as centre of the water wheel and linking to the pedals on a bycicle to use the chain and sprockets as a gear box my first idea was using the segway motors as the axle centre hub but felt they would not work as they would not be spun fast enogth
How much would this generate
Depends on the rest of the setup, but they should be happy with about 300-400W continuous.
What about universal motors? I know you can use a bridge rectifier and capacitor to charge the external windings magnet and it is in some way related to the rating of the capacitor
Field winding motors can be externally energised and induction motors can generate if you get the input revs right, but it's always more hassle and lower efficiency than permanent magnet. Just that the latter usually has less available options..
ok steady
Rapais so tem gringo nos comentários , queria saber se tem q ta em fat32 ?
No pma? OR derrite?
? Derrite ?
FeRRITE? MAG?
Motorbike alternators are PMAs.
You are using automobile part to drive this generator, so the most simple way i to directly use a car alternator, they output also more power than motocycles alternator and are also very common.
Car alts are higher power and generally more available, but aren't permanent magnet so have lower efficiency, and do about a half to a third the volts per rpm. Also pretty heavy to mount and turn.
Very hard too spin if u self excite it and need high rpm
@Opensourcelowtech.org what RPM would you need for a motorbike alternator from a turbine?
Nice idea Thanks for sharing
Can I charge a 12 volt car battery with that. It would be very interesting if could run my house with multiple of them in my stream.
Long as you've got a water supply capable of spinning the turbine fast enough to get the voltage over 14.4DC while under some useful load, then yes.
What's your meters drop and liters flow, roughly?
anyone point me in the direction for getting cheap motorbike alternators in the UK?
Local wreckers are usually best. Or online classifieds.
What is the output voltage at ac?
Depends, but often around 18VAC per thousand rpm. Can be single or three phase, some have an exciter coil which does about ten times that voltage but at low max amps.
They're not too bad, overall.
@@OpenSourceLowTech rewinding it at more turns will be great for lower rpm by the way thanks😊 make more usefull videos😊😁
Hello Daniel, thank you for sharing this, i'm glad to see it's feasible. I'm still learning and seeing you really motivate me.
I'm currently trying to plan/engineering something very similar to this in the purpose to make a little energie for my offgrid cabin with a beaver dam. ( 1.5 m of head). Hope it not sound too much crazy! Lot of water, but low pressure and freezing problem in canadian winter.
I did not see the AC to DC converter, am assuming the output is AC since it's a motorcycle alternator. I assume a motorcycle alternator would be much more efficient than a car alternator at less RPM ? the car option is already somewhat mounted.. so ? what is best ? Before seeing your video, I was thinking to maybe rewire a car stator in a different gauge/size copper wire.
I also wonder if the bicycle chain can work on a horizontal plan, or would it "derail"/fall ( sorry, I hope this word exact, English is not my mother tongue). I want to put a turgo wheel horizontally, so I can maximise the very low head I have.
EDIT=> I've just seen the demonstration at the start ! =D thank
On another subject/ idea, Do you think it's possible to reverse a small electric boat propeller to make it generate electricity ? I mean.. it's a motor.... and it's already have a propeller mounted on it.... Good idea ? Worst Ever ?
i hope you would like to share your insights =)

> assuming the output is AC since it's a motorcycle alternator.
Yeah they tend to be three phase AC, but can be single and some have the third coil as high voltage for the starter circuit.
You'll need a basic bridge rectifier if you're plugging it into anything DC.
> I assume a motorcycle alternator would be much more efficient than a car alternator at less RPM?
Exactly that, yes.
> the car option is already somewhat mounted.. so ? what is best ?
I don't usually bother with car alts. They're about three times the power, but at about half to a third the volts per rev, and like you say not very efficient. Also quite heavy.
> I was thinking to maybe rewire a car stator in a different gauge/size copper wire.
Lot of work.
> I also wonder if the bicycle chain can work on a horizontal plane
You wouldn't want to string over too much of a distance, but if you can nestle the two sprockets closeish together then it should work fine in any orientation.
> I want to put a turgo wheel horizontally, so I can maximise the very low head I have.
You won't get much efficiency out of a Turgo at 1.5m head. My siphon turbine is meant for that kind of niche.
> possible to reverse a small electric boat propeller to make it generate electricity?
That's basically what my turbine is, but with a tube around it to generate more flow. A boat prop would I think be a more efficient runner shape, but the PSU fans a lot easier to source.

Здравствуйте, Даниэль, спасибо, что поделились этим, я рад видеть, что это возможно. Я все еще учусь, и видя, что ты действительно мотивируешь меня.
В настоящее время я пытаюсь спланировать / разработать что-то очень похожее на это, чтобы получить немного энергии для моей автономной хижины с бобровой плотиной. (1,5 м напора). Надеюсь, это не звучит слишком безумно! Много воды, но низкое давление и проблемы с замерзанием канадской зимой.
Я не видел преобразователь переменного тока в постоянный, предполагаю, что на выходе переменный ток, так как это генератор переменного тока для мотоцикла. Я предполагаю, что генератор мотоцикла будет намного эффективнее автомобильного генератора при меньших оборотах? автомобильный вариант уже несколько смонтирован.. так? что лучше? Прежде чем увидеть ваше видео, я подумал, возможно, перемонтировать автомобильный статор медным проводом другого калибра / размера.
Мне также интересно, может ли велосипедная цепь работать в горизонтальном плане, или она «сойдет с рельсов» / упадет (извините, я надеюсь, что это слово точное, английский не мой родной язык). Я хочу поставить колесо turgo горизонтально, чтобы максимально использовать очень низкий напор, который у меня есть.
РЕДАКТИРОВАТЬ => Я только что видел демонстрацию в начале! =D спасибо
Что касается другой темы/идеи, как вы думаете, возможно ли перевернуть гребной винт небольшой электрической лодки, чтобы он вырабатывал электричество? Я имею в виду… это мотор… и на нем уже установлен пропеллер… Хорошая идея? Худший ?

motor cycle batteries are 5ah rating, these stator only produce enough amps usually 10% of battery rating, or 500mA, you'd be ;lucky to get 2A on that stator. another problem is that only single phase, manufacturers will not allow a motor cycle with a 5ah battery to charge greater than 10% or 500mah or the batteries wouldn't last quick charging lead acid motorcycle batteries, best generators are 3 phase, you can get 1.73 times more power than single phase
Bike alts seem to vary pretty widely, and yeah they're not the perfect option for this use, but do usually do better volts per rev and overall power than anything else I can find which is prevalent and accessible in low resource environments.
@@OpenSourceLowTech i have a yamaha mio that had 5ah battery, since i change mg head light to HID 36 watts, i change my battery to 7ah, but still i would drin the battery which only eats 3amps of my head light, it would drain it in a hour or so even while riding, i even bypassed the charge controller and still had problems draining, motor bikes have a small battery even if i replace it with 7ah or 9ah, 10% safe charge is only 700mA 900mah respectively, unlike cars 50ah battery 10% safe charge is 5amps, have you tried measuring power generaton of the segway motor?
Battery specifics would be one of the main holes in my knowledge. And also end up pretty bespoke to the install in question. I generally just ask some experts and defer to their judgement.
As I understand it tho a motorbike alternator will charge a car battery just as happily as a bike's.
Hoverboard wheels should be good for at least 300W nominal output, depending on specifics, and probably maybe like 4-500 if pushed.
They usually do about 55VDC(rectified)/krpm and seem about 10A rated.
@@OpenSourceLowTech agree, unless we go lithium, we can charge quickly, 1C to 10C depending on specs allowed, but lead is really design yo charge 10% for 10hours so not to damage tge plates. Ive seen YT diy making their own stator gens specially wind gens, hydro is more reliable as lonh as yhe source has a large capacity. So gens have to be designed depending on speed rotation and volume/ time. Anyway subscribed hope to see more of your good videos
Have you experimented with magnets? Or perpetual motion generators? I know they say it's impossible but just wondering if you have tried it and what your thoughts on it is?
Perpetual motion is a lie, clickbait only for innocent desinformed people. If you see any video claiming that don't click, just report it is all a lie, the machines have hidden cables and that is how they are being powered. Nothing has 100% efficiency and you need energy to run stuff. You can always use "free energy" like sunlight but never believe that a generator powering a mechanical screwdriver that is itself powering the generator like the generator had 100%+ efficiency. All power is finite and is some form of a pre-existing energy like batteries use chemical energy to provide voltage and power a lamp. Those perpetual motion generators loose energy do to friction (air friction also) and as such you always need to input some energy for them to rotate. You can also see they are a lie because when a load is connected they rotate at the same speed when in reality wen you apply a load to this type of generators they get harder to spin. There are a lot of good content creators debunking this predators in youtube just dig deeper don't believe everything you see , mainly when they don't explain stuff and just run background music in the video. Also there is no conspiracy if there was such a thing as perpetual motion machines they would be in use and electricity, heating, transport and stuff would be free, and no big corporation could hide it from the thousands of good engineers scientists and informed people of the world.
Didn't get this one recommended
How do you mean?
@@OpenSourceLowTech yt didn't recommend it to me, even though I have the notifications bell activated
Oh. Well that's weird and not super helpful of them.
Amazon great place look bike parts cheap.
I think you can mass prduce it and we all will buy, i don't want to buy those chinese generators and i am not good at making things
Potentially, but postage would be an issue.
You can probably find a local tradesman who could make one up for you.
@@OpenSourceLowTech yeah didn't think of that thankyou
Yeah I think you told her the truth
my god why cut those poor spokes, just use a screwdriver to «unbuild» the wheel...
It's waay faster to cut them.
I do keep and reuse them for other things tho.
