Way back when, in the 70s, I had a 3 level Savonious rotor 6 feet high driving an auto alternator at the base. The wings of the rotor were spring loaded for high wind control. Storage was 6 salvage 2 volt telephone company central office batteries. These batteries weighed about 250 lbs each ! I used this system for emergency back up for my amateur radio station. However it was so efficient that I ended up using it full time, even proving lighting for my Ham Shack. I never could come close to fully discharging those batteries !

Why not use a vbelt OR a multibelt from a actual car dynamo the come in Manu size ant no noise also u could use the pully from it 👍👍👍

[@Oxendine9381]

@@diypapie8428 I think the chain could withstand the external elements better than a vbelt. Thats just my assessment though.

[@wmman8256]

@@Oxendine9381 the chain will last longer and be stronger than a v-belt. That being said, the v-belt is not going to corrode or rust and sieze up like the chain would. As long as the chain is oiled and kept from rusting it will provide the longest life, and can carry the most torque. It won't slip like a belt would. The belt will be quieter and easier to replace or repair than the chain would be. Both methods are very good options for this project. I like the chain because there are different gear ratios and you can adjust them to find the optimal gear ratio for the wind speeds you have available. The belt isn't really adjustable easily. Being able to adjust the gear ratios will allow you to get the best performance from the turbine by simply adjusting the gear ratio. I've been working on my design for a vertical axis wind turbine and I am using the chain setup so I can adjust the gear ratio and optimize it for the winds I get here. I think that having a chain gearbox, basically is what you have with the different gears and the ability to change them easily like you do when you are riding the bike normally. It will allow me to always get the best ratio to wind speed and create the most electricity from the unit as possible, just by changing the gears being used. It also allows for the incorporation of more than 1 vertical turbine that utilizes the same chain and gears for 1unit or for 2-3 turbines. All connected with the same chain and working together to power 1 generator. 1 chain can connect all 3 turbines and utilize the same chain to turn the generator and create power. Useing the gear system from a mountain bike gives you several variable speeds to turn your generator and increase or decrease the torque of the turbines to achieve the maximum speed on your generator and allows for the most efficient usage of the wind and generator to produce electricity. Not many designs can change their gear ratios to utilize the wind speed as they fluctuate throughout dayand night, no matter how fast or slow they blow. I think this design will work better than most other designs like the traditional style wind turbine. Probably not the simplest design for a wind turbine but, I think it's a much better design and is capable of producing more power than the standard designs available. Building a vertical design is easier, more flexible and more powerful designs that the other ones. No need to have the unit turn into the wind to catch wind to turn the blades, it's round, so it catches the wind from all directions without having to rotate the turbine into the wind. Also no need for a vain to change the attack angle of the wind to the blades. I believe that vertical turbines are the future of wind power in the world, and hopefully we'll be seeing many more of them powering homes across the planet

[@timway6839]

Cool

[@TheRustAdmin]

thanks for being so simple in your design, most people don't realise any motor works as an alternator/generator, it's also great how you made it out of scrap instead of getting it manufactured expensively :)

[@virtec3d]

I just accidentally stumbled upon these videos of yours. Man, what a clever guy you are. With the current situation here in South Africa where our electricity supplier are run into the ground by a greed and hate filled government who is now also in the process to sensor all our online activity like in China and Zimbabwe, these ideas of your will for sure make quite a few things for us South Africans possible facing random blackouts and all. Our only challenge now is getting water, since our water and sewage system will also collapse when the electricity supplier collapses.

[@MarkH10]

I have been looking for vertical wind turbines exactly like this as a power source. At first glance I thought this to be a vert. design, but I believe this works in both orientations. Thank you so much for this. The discarded treadmill motor I recently harvested has a multi groove belt, which may also work well.

[@Oldtechmech]

You need emergency brake when the wind speed is extreme!

[@carlvickers1947]

Good job buddy.. I see a lot of back seat engineers that have probably never gotten off the couch telling you how to do it... It is fun doing things for yourself and a great learning experience...

[@todloeffelholz7921]

That’s a pretty good design, I live in Albuquerque NM. And we have winds with gusts up to 70 mph so I would have to beef up the design and put a brake on it

[@philliphaasbroek]

Fantastic. Look very stable and well balanced. Well done. Love the sprocket idea, so you can put a stronger bigger generator what will cause more resistance, and you can adjust the sprocket to cancel the problem out. Hope the neighbors don't complain.

[@David-mc4ny]

That's a great practical setup. Matching a generator and drive system to the torque and RPM of your VAWT is often difficult on a limited budget. Thanks for sharing !

[@agsensenz9464]

Thanks for sharing. I've been excited by VAWTs for many years, but watching your upload showed several new approaches. Very much appreciated, and keep up the great work.

[@EdwinHenryBlachford]

nice. Similar to an 100year old idea - the flip-flop windmill - so proven technology. Points: basic wind design speed is 42m/s in non-cyclonic areas of Australia (151kph) so if installed in an urban environment the design would need to be tested to that, but the real problem with this type of turbine is ... it can't be throttled. You can never stop it or slow it down. However, these turbines are efficient. Further points... most local government in Australia will allow a windmill up to 10m in height without needing approval. .. a toothed belt in place of the chain would quieten it down. Good work

[@Giblet535]

Very innovative chain drive. I like it. Wing profile is a Lenz variant. Would like to see power output in the future but will look through your videos to see if it has already been done.

[@truetech4158]

Rather than a chain or a belt, it would be best to go with a direct drive system, even if it requires one added linkage point to angle the rotation, a pivot point, think gears, they can modify an angle upto 179 degrees, though 90 is enough if a direct drive with a inline motor shaft isn't possible. That's not even accounting for gears used to spin the motor faster according to windspeed adjusting them similar to how a thermostatic switch functions, only the pressures are being created by the speed of rotation to activate gear changes. Chains and belts eat up alot of potential energy, and when examining wind turbines, you definitely want them to operate using the least amount of wind to be most effective. Least moving parts, lowest cost, least running costs, lowest maintainance.

[@rodhigh7]

Relative to my comment below. I like the Savonious because the weight and rotational power are centered on the mounting pole. In my case, the alternator is mounted at the base. Of course this means the entire pole must rotate. This is accomplished with The base of the pole rotating on an auto front wheel bearing with wheel bearings above and below the rotor. these bearings are mounted on metal plates which provide attachment of the guy wires. The base of the rotor is 10 feet above the base. I live on top of a ridge and winds can get pretty strong here in the high desert of SE Arizona.

[@oBseSsIoNPC]

The Turbine design itself is good. The chain drive is not ideal though, but MUCH better than a belt, good job on the materials used!

[@richardb4787]

I wonder if, since bike gears are being used, somethings to get could could be done with the shifting mechanism? As the windmill goes faster, it would change gears?

[@richardb4787]

With a 24-speed bike, 3 front gears and 8 rear gears, a wind generator would have a lot of torque to operate heavy loads.

[@alessandrogiannarelli4677]

Adjusting speed of the alternator would only change the voltage. Which is not necessary for a simple DC application, like It Is for a industrial AC Energy producing Power plant.

I wonder if it's possible to make a good belt with common materials to avoiding buying one.

I'm currently experimenting with a Range Rover grooved belt and pulley around the wheel rim and driving a hoverboard wheel as the alternator. Results posted when I have them.

[@joelschermerhorn5447]

A big 5 stars for a working homemade wind turbine, as it takes a lot of effort to get something functional. But, there is still too much friction, as I hear the chain clanking away while turning, and this friction robs output and efficiency. You may want to balance all the wheels, especially the turbine wheel, and this will improve output. You may also want to install an adjustable brake so when the wind gets too strong, you can increase friction on the turbine wheel and prevent the motor from over-speeding. There are possibly other things you could add, but I’m not familiar with what they are. Just a few friendly thoughts.

[@leodrake252]

awsome build,keep up good work,just remember never give up as most nay sayers here havent built anything even close but beleive in there own "expertise"

[@jimallen9442]

Its easy to be a nae sayer when real time figures like power to wind speed are not present. Also, so many things about the Savonius wind turbine are just inefficient, and that is before adding gears. If this machine is capable of producing 1K, which experience tells me its not, it would need to be a hurricane outside.

[@kreynolds1123]

It's not a Savinous turbine. That is radically different from this. But, the lenz2 turbine is a hybrid with both lift and drag.

[@sambo5562]

As one person wrote earlier. It appears you have to much friction between the wind vain and the generator. It looks like your chain tension's guides are causing a lot of friction. I would suggest you shorten your chain and spread your chain guides further apart thus reducing the drag on the chain.

[@ohtaren8052]

Nice work! Have you thought about making the fins more of like a sail rather than a 180 degree curve. I'm not an engineer but it seems like this would create a little bit of dead air space and not take as much advantage from the wind because it pushes back rather than out and away.

good project at home wind generators are certainly cool , i know a lot of the people around me are getting into biofuel generators most just do steam but some are producing synth gas and running the old engines form their trucks on it and feeding the power back into their home. man i kinda wanna do a free energy project now

[@petersmythe6462]

So if it were constantly running, it would generate 1 kilowatt, which is around $0.12/hour, depending on location. Which would give it an ROI of about 52 days. Not bad for a renewable power source, although this doesn't take into account downtime, maintenance, or labor cost.

[@johnthaller9501]

Look at your electric bill, and the actual cost of the electricity, without the service charge and tax on that service charge. This is the cost of having a connection to the power company. It will not go away even if you do not use any electricity. Your real cost per kwh is about 7 cent. As for the output of this home made turbine, 1 kwh is probably the peak, not the average. i bet it doesn't run most of the time. More likely 25% of the time. So, we are up to a year in payout, and I highly doubt the rig would last a year.

Your scooter wheels will make drag. Just use a vertical slide for the generator to use gravity to pull down on the chain. Will increase efficiency by 10% +

[@OpenSourceLowTech]

I've since progressed to a belt, but how do you mean?

[@MrSmithToday]

@@OpenSourceLowTech the gravity of the generator would pull down on the chain or belt. Like a vertical slide to keep the generator held so it can only move up or down. The weight will pull down on the belt.

[@mikeclarke3005]

OK, best gen is going to be a 3-phase alternator type, more power smaller size, if using a dedicated alt less moving parts is a must for low wind. better if can build with the rotor have neodymium magnets and windings setup to produce a three phase output and rectify therefor no friction other than bearings.

[@FBPrepping]

You have made an excellent job with that turbine. Your video is very detailed and your explanations are simple but very complete. Is there any particular reason to use a square pole instead of a round pipe with more diameter?your design is awesome,anyway and it seems to work flawlessly. The idea of using glue for the chain is simply clever. In my area the sun would affect it in 4 or 5 months though. Great job and as engineer I can tell you that simplicity is key for do it yourselves people. Thanks for sharing this with us and congratulations. You made a very important addition.

[@mkeyx82]

What is the glue used for, I didn't understand that bit.

[@kreynolds1123]

mkeyx82, take a chain and glue it all the way around the wheel. That will serve as teeth for the chain that thansfers power from the turbine to the generator.

[@FBPrepping]

You may use some other method for attachment of the chain mkeyx82 but he used glue because it is fast and easy. I found a glue used here to repair plastic tanks that it looks like a very strong resin and it is UV resistant so I think I will be able to reproduce as exactly as I can this design...but I have a piece of pipe instead of a square pole lol.

[@mkeyx82]

You should be able to calculate load bearing capacity for that pipe. It's counterintuitive (somewhat,) but I know that a pipe will be able to sustain more load than a rod of same diameter. It's reasonable to assume it will work the same way for a square pole, however I don't know how would the pipe diameter relate to square pipe diagonal. Thanks for the explanation. Why should a chain be used on this thing anyway, looks quite superfluous. IMO it would be better to have the generator touch the wheel tangentially, with an elasticated support to keep it pressed on the wheel firmly and a smaller (rubber?) wheel affixed to the generator axle for traction. Depending on the smaller wheel diameter, desired rotation speed could be obtained. Or even maybe have a similar setup, where the bike gear would be left on the axle and the chain affixed to the wheel (along the circumference) in a closed loop. If the gear would touch the chain tangentially, I'm willing to bet it would still spin with quite a bit less friction.

[@kreynolds1123]

mkeyx82, strain on the gen sprocket teath is related to how many teath are enguaged. Thought experiment: would you rather have 700 foot pounds per second (950 watts) distributed over 2 teeth, or 10 teeth? Granted, one would never have that kind of power continuously, but a bike sprocket normal use is far closer to human powered at 220 foot pounds a second (300 watts) over 8 to 10 teeth like in a bike.

[@jasongroupindustries]

Hi, Am impressed with the wind turbine you made and was wondering why you didn't use the gear on the bike wheel instead of attaching the chain on the wheel rim??

[@InventPeace1]

I guess thats the real question: with the sail design* on the vanes, what is the efficiency compared to the same surface area what's the standard windmill design with the horizontal shaft facing straight into the wind? * knowing that a sale is really a vertical wing like from an airplane and that it lifts itself into the wind instead of just being a resistor altogether of the Wind when it comes back around the other side. Personally I like the slow-moving large vain Dutch type of windmill which is safer because it's slow moving and fairly lightweight vanes even though they might be 30 feet long because they use sailcloth, which can be furled in relatively easy with centrifugal counter weights that in a high wind would activate to furl in the sailcloth to avoid over speeding the windmill. Imho any windmill needs at least three independently separate braking methods to be safe but the inherent slowness of the Dutch large vane slow-moving type helps this all together for Safety by default.

[@mamoshimamoshian9078]

Beautiful Brother. I hope that you stil are doing these kind of things. I Guess until now you know that every theth on your chain is going to work against good result, so you have to bring the number down as much as possible, but the bicycle idea Great. I hope that you are stil interested in this

[@gfharper]

Too much friction - would take a really strong wind to accomplish much. I think the main resistance is where the two small wheels meet - maybe if they're farther apart. Why does the one bicycle wheel have teeth? Once the rig is up, it looks like the top wheel will get lots of weather - since the bearings are designed to be horizontal, the top wheel - maybe both will quickly freeze up, unless it is maintained properly. I like spray white lithium grease - easy to apply.

Great idea but how do you regulate the voltage so as to not overcharge your batteries? I know it can be done. I'm just wondering how you do it. It is easier to do if the generator has field windings but it's more difficult in a permanent magnet setup such as this as you have to control the main output rather than the field input which is at a lower current. Permanent magnet motors are famous for increasing voltage above their operating voltage when they are sped past their operating RPM.

How do you regulate the speed for very high winds and still draw energy from it?

[@danielswift7776]

See some of both people picking (A typical , of you tube junkies, that don’t make crap) and the opposite is the cheer section! I’m not posting for either, just some Quality inside, from my personal, educated, and professional point of view. I like when people use their minds and hands. 1) is the tapping from the vain hitting the guy wires? 2) what occurs in very high winds? As most turbines are designed to free spin at a given rpm. So the extremely voltage generated at those high rpms do not burn out the brushes and the voltage regulator ( rectifier) 3) the chain being glued in? Good hack, how ever William Ferris over came chain and cable friction by using rubber. As a batting between the elephant ear at the end of a spoke. The cable or chain would ride against the rubber, to turn the Ferris wheel. The ELI -12 and the Garbick -12 are the same. They revolve 26ton of steel and people with friction generated by cables and chain to rubber. 4) idler-wheels or tension wheels? You used good engineering fundamentals, there. Ok, but I didn’t see one stationary and one under spring tension. This is needed because Of the load of the wind pushing changes. They will ecsorb the shock and jerking, caused by the sudden change in wind. Plus the new chain will stretch, once worn in. Some slippage is good at times, usually for quick and unexpected Load changes, like wind. 5) rain guard over the motor/ generator ( maybe an alternator depending on the type you use). Good thought again. Be sure to you a cable lube or dry lube. So sand and debri don’t gum things up. 6) turbine construction. Over all quality craftsmanship. I’m not sure the strength in high wides is built into the portion, with out back bone support. A strong local storm can tear apart some of the best made. But the geometry of yours is great. 7) Round or square poles ? Use the simplest to work with. Capping off the top will slow rust inside. Lastly, As young man I ran an 45’ ELI-12 for Taylor and son amusement out of Annapolis,Md. The late owner Mr. Charles III, was one of five Amusement company owners whom forged the first ride inspection standards used still today. Him and his son Cliff also where to first to use nylon bushings on the Journal bolts to carry the tubs you sit in. I worked 18 yrs in the utilities industry. Including as a Baltimore Gas & electric Class A Trouble lineman. I also now live in Yucca Az off grid and wind generation is in part of my owner system. We can get steady winds 30-40 mph and gust 60-80.

Hey, great comment and questions. 1) Yes. Since fixed. 2) The turbine itself has been tested up to 105 km/h, though I've strengthened the design significantly since then. It does about a sixth the rpms of a horizontal at six times the torque, so overspinning isn't really an issue. 3) I'm now using an automotive belt, tho another commenter mentioned tumble drier belts which I'll check out and might be a good option. 4) I'll see if I can get away without a spring on the tensioner pulley, but shouldn't be the end of the world if I need to incorporate one. 5) Good tip on dry lube. 6) I'm hoping the more hardcore design will take gusts of up to 120 km/h, but will find out over time. 7) Square is a bit easier to attach stuff to. Did you check the full build tutorial in the video description?

Why are people so negative with this guy is like they have so many down this likes of this because people just don't want to believe it's possible it's just like with hydrogen they think the vapor doesn't exist.. it's ridiculous how people are so freaking negative I think there's people like trolls that they government pays to do this to get on here and negative thumb it down so that people won't try to do something for themselves if you believe don't believe the negative connotation is look for the solution in this that way you don't have to look at all those thumb Downs... because people are just being negative but I think it's truly people that are being paid not these kind of things I've seen this on other videos happening when it's something very obvious that works..

[@maxnovakovics2568]

Definitely people have automatic bots that go around just disliking things

[@simonmoore8414]

This is fantastic. Great innovation. 👏

[@rastamanralph6670]

Good job.that's the same way I was guna b doing it but thought a belt might b easier and better.av got 2 motors like that but bigger and live in a very windy place.

[@xMrJanuaryx]

Nice, I find it interesting that you chose to use a chain. I think you might have been able to get away with mounting the motor directly to the low speed shaft had you milled a smaller cog to fit that linkage and welded it to the high speed shaft; a 2 to 1 ratio would work. Also, was their any particular reason you chose to use those 6 large vanes? I would have figured a more simple 3 blade system with a wind vane to orientate them would be more efficient. Anyhow, good luck on your future modifications!

[@OpenSourceLowTech]

The chain worked kinda ok but wasn't quite as I wanted so I'm now experimenting with a belt, which has other considerations but I think will give a better result overall. More revs means more voltage and less line losses, so it's nice to be able to come off the bike rim as a 60cm sprocket/pulley and get about a 12:1 gearing ratio more or less for free. It's six vane because that's as large as I can make each of them from those materials, and twice as many vanes means twice as much power. A tail or similar isn't necessary as vertical axis turbines can receive wind from any direction simultaneously.

[@xMrJanuaryx]

Obviously, I am not a wind turbine expert but that being said all the commercial wind farms I have seen use a 3 blade + wind vane system. So apparently, there is a benefit to that system over any other system. I would assume it has to do with the power loss you have when using belts, chains, kogs and in general create resistances from input to output.

[@OpenSourceLowTech]

They do fine in good conditions, but verticals tend to do better when there's turbulence, obstructions, etc, which is often the case where individual people would be putting their own turbines up. Also the economic and commercial considerations are completely different between the industrial and home scales.

[@j-man6001]

Cool concept man, I thinking on a similar water version. Peace out

[@jorgeosmar5429]

Un buen trabajo amigo! Yo me he encontrado con que mientras más hierro metés en el sistema, aumenta el coeficiente de resistencia por roce. Si eso lo sumas al efecto lenss del mismo generador, no hay viento que lo mueva eficientemente. Por eso se me ha ocurrido que la respuesta está en juego de poleas con cintas de goma dentada. Como lo ves?

[@OpenSourceLowTech]

I'm now doing things in quite a different way, check my more recent videos.

[@tedrowland7800]

I'm not an engineer. Let me ask any way. Would this work better on a car spindle with a disk, that has good roller bearings and and high heat lithium grease. If used with an axle assembly, (C.V. joint) for front wheel drive, it would not be too hard to assemble and solve a problem, by making it direct drive, or a gear ratio setup. The whole thing can be had at a junk yard for about $75.00 U.S. You could build larger vanes, out of a little thicker material, that would stand up to excessive winds. It's just a thought. Love your video.

[@OpenSourceLowTech]

That would give a more solid build, yes, but as it is it works well, can handle winds over 100 km/h for years, and, critically, is very easy and cheap to make.

[@rodneyhays3796]

The clacking noise while rotating will lead to malfunction later, you can be sure of that. it is extremely important that all mechanics be completely smooth in motion, otherwise nice job. carry on.

[@JesseCotto]

It was nice to see it working.

[@sosteve9113]

great idea,nice to see it works

[@RedfishInc]

Seems to turn well enough in a good breeze.

[@wolver1n]

yes without a chain in the video...

[@stevensgarage6451]

Seems more like a youtube prop vs something actually built for generating useful power. Any videos showing how many watts its making at a few different wind speeds? Any video of it actually powering anything? This is your most successful video, Seems like if this actually worked and generated power youd have a proper sequel or demo video.

[@Mavrik9000]

The rollerblade wheels seem like unnecessary extra friction, perhaps stretch a strip of rubber tire into the wheel grove.

[@mattguzda853]

I love the idea of energy independence but to what extent can u generate power? Run a fridge tv lights and space heater? How wasteful can one get?

[@DiyEcoProjects]

Hi, i like your project, well done... Can i ask why did you choose a chain over just mounting the generator directly to the shaft of the vawt?

[@OpenSourceLowTech]

The way it's mounted the shaft is immobilised, but the main reason is rpms. The higher the voltage the better for a couple reasons, so being able to use the wheel rim as a pulley is pretty useful. I'm currently in the process of replacing the chain, which kinda worked ok for the most part, with a belt which while slightly trickier to source is probably a better option overall.

[@neilmacleod5371]

Neighbours must love the clicking noise all night long , why not use a quite cogged belt ? Like the ones that drive your overhead cams

[@paulbester7097]

I've experimented with a lot of motors and nothing gives the op of a treadmill motor . Found them at junkyards ...

[@walterarmijo5668]

If the generator is at 1.5 hp and 60 km/h with 90volt out put if its going faster on a windier day will it produce more volts or only put out 90volts even if its hella windy

[@HAPPY2ISI]

Looks good, but why you don't use two more motors instead of this two round-rubber-thing?

[@OpenSourceLowTech]

I thought about it, but they'd need to go to the charge controller as separate channels, if you just wire them in series it's quite difficult to get the voltages to work out and not just have them powering each other as motors rather than generators.

[@HAPPY2ISI]

Ah ok. Now that make sense. Btw i see your other videos... nice 👍.
