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

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.

That's actually a very good idea, thanks.

Thanks. Yeah born and raised in New Zealand, tho been mostly out a while now.

Daniel, I'm your biggest fan that you don't know. I'm studying all your turbine prototypes, and could really use your help with the hydroturbine. I plan to help several communities in Africa and the Caribbean, and I plan to give the credit to you.

@@solarintel1727 Hey, glad to hear it. You can message me via the email address on opensourcelowtech.org I'm happy to answer any questions you have.

Don't worry about credit, mostly I need field use data...

Depends on variables. How much wind do you have and how much power you need?

From there originally but currently in Europe, mostly Scotland.

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.

​@@OpenSourceLowTechhello mate great vid your a good teacher mate make it less intimidating which is great...anychance have a chinwag if get this cheers mate

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.

Any questions let me know.

You mean gearing ratios?

@@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

Yeah hoverboard wheels are usually pretty good for these kinds of applications and I use them quite a bit. This one is meant for parts of the world where they're not available.

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

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.

No, they're much bigger, and a very different shape. Bit harder to get too.

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.

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..

Yeah wreckers or an old bike is usually best. Can get them second hand online, but can cost a bit.

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.

> 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.

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.

@@OpenSourceLowTech =) Thank for your time, it's appreciated.

@@OpenSourceLowTech Roller chains only work horizontally under high tension, which makes them inefficient.

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 ? Надеюсь, вы поделитесь своими наблюдениями =) с уважением =) Этьен

@@AnatolZelenkoff Did you copy the original comment and repost it? Why, if one may ask?

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.

@@klyddmeisters can u share any information please , ? I've built a altinator To a gx160 Honda but poor power output unless Very high rpm

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..

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. My email's on the opensourcelowtech.org website, feel free.

@@OpenSourceLowTech Thanks I will do that please note the size of the housing is 5.25" x 5.25"

@@OpenSourceLowTech check your email pls.

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?

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.

Most bike alts should be good for about 300W continuous or so, but they vary. I've yet to burn one out.

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.

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.

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

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.

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.

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.

Depends on the rest of the setup, but they should be happy with about 300-400W continuous.

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

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

Local wreckers are usually best. Or online classifieds.

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

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.

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😊😁

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?

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?

? Derrite ?

FeRRITE? MAG?

Motorbike alternators are PMAs.

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

Potentially, but postage would be an issue. You can probably find a local tradesman who could make one up for you.
