Kilowatt wind turbine and pole for under $150

/ opensourcelowtech
Turbine build tutorial: opensourcelowtech.org/wind_tu...
The generator is rated at 1.5HP / ~1kW which the turbine should be doing in about a 60 km/h wind, at about 90 volts. The turbine has been survival tested up to 105 km/h.
This video is just an incidental update, mostly on the new chain drive prototype and pole mount configuration, I'll be doing a full documented update at some point soon.
The cost breakdown is about $25 for the turbine itself, $45 for the treadmill motor as generator, and $95 for the pole, steel rope and fixings etc.

Known Issues With The Video:
~ Yes the steel ropes start out mounted below the turbine then jump to above it, turns out they work a lot better up there.
~ Yes the pole wobbles a bit, in future I'll have probably just some polyprop rope to the pole mid point to lock that off and stabilize the whole thing.
~ Yes the chain is off when the turbine is up and spinning, I didn't have it tensioned well and it dropped but then also didn't have the time or assistance to take the pole down and re-establish it before I had to leave. It does work fairly well tho.
~ Yes for now you're going to have to take my word for that.
~ The video is largely out of focus but my phone camera either auto focuses constantly or not at all and the latter is slightly less annoying.
~ The turbine does pop a bit when it spins, but it's not loud and I'll try to resolve that.
~ Yes the back two ropes are crossed at the top, that's for reasons.
~ Yes I say ummm a lot, like I say this is only meant as an update and I'll do a nice full video with amazing production values very soon.

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.

[@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.

[@rodhigh7]

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 !

[@diypapie8428]

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 :)

[@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 !

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.

[@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.

[@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.

[@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.

[@bacilluscereus1299]

Thanks for sharing and the inspiration.

[@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.

[@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

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.

[@judithmdza9500]

Great job getting this working with what you had available! Obviously lots of improvements could be made, would be interested to see the haters post their own improved versions working to the same budget ;) I think I'd try and use a belt drive system if I was having a go, maybe with a 3D printed pulley on the motor. I wonder if it's possible to make a good belt with common materials to avoiding buying one.

[@OpenSourceLowTech]

[@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.

Would drilling a series of holes and using zip ties work as well as gluing the chain? Maybe less work

[@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.

[@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??

[@jeffmccrea9347]

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.

[@Frank040675]

Why no chain attached at the end when it is spinning? Will it only start spinning without the chain and therefore just be an ornament?

[@TheGreenLift]

hey great turbine- do you think you could make it silent with few adjustments?

[@OpenSourceLowTech]

I'll be aiming to. The popping is something flexing somewhere, which should be just a matter of a little reinforcement. The only other sound it makes is the buzz of the chain drive which may be a little harder to eradicate but if it's going to be a problem I'll try encapsulating the whole generator and see if that does the trick. Would also help for weatherproofing.

[@Alex-sg3pb]

Well done, re-purposing old items into DIY wind turbine. I would probably be more inclined to use an AC motor/generator instead of DC motor/generator. if not possible then perhaps use DC to AC rectifier so what ever power you generate with the turbine will be cheaper to cable back to the house with little to not much loss in AC, then at the house just rectifier back to DC.

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

[@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.
