Great video! I worked with small wind generators for a number of years. I noticed a stress point, on the way the blades are mounted to the plastic fan blades, over time the original blades will stress crack and fail. If you ad a blade brace to tie in all four blades on the front side of the blades, you will eliminate much of the stress on the original fan and give your windmill more longevity! Ed
I was thinking about that, 'cos these things are built to a price. My perception is even a small diameter secondary disc / "washer" the size of the original fan , would help reduce the flex / stress on the fan root..
Ya, I was thinking the same'. Those radiator fan blades always look like they may explode at any moment after a decade on a car under normal use, can't imagine how much worse the stress is when doing something like this lol.
If you actually add a cone to the nose of the blade that covers 20% of the blade surface you reduce the stress on the blades and increase the efficiency of the whole system because it reduces the drag.
I love these videos and love the comments even more. Learning really is a communal experience. For 'free', and if you have some time, you can find online where people carve the blades just out of scrap wood. Some wood blades have been known to outlive some metal ones. I'm going to remember that about the washers and cone. I have a neighbour with quite a junk collection, I mean 'stuff' collection, I'm going to go looking for fans.
Small heads up for anyone making these: BROWN soil pipe is prone to deteriorating when exposed to UV light, so if you have to use brown soil pipe, I would suggest painting it or using some kind of UV inhibitor Modern black, grey or white soil pipe, on the other hand, is UV resistant 😉
2 minutes into it and i knew i could spend an entire 48 hours with you in a shop and it would feel like 4 hours went by. Curiosity, tools, knowledge. Like kids in a toy store. Awesome.
I'm female, older, still working, and am limited in both financial resources and time. I watch a LOT of UA-cam vids on how to make projects simply, inexpensively, and that save me time. Your vids are always spot on and simple. So they are my first go to when I am looking for a solution. I love your shop! I agree with another comment, you need a companion video on how to mount this, and I would add, your simple windmill needs a tail so it can turn with the wind, as well as an easy to use breaking mechanism for when there's too much wind. Would be interested in a vid on these things too. Thanks for your videos! I'm a huge fan, excuse the pun!
That was actually pretty awesome. I never considered the fact that there are HUNDREDS of inexpensive but robust, long-lived DC motors that can just as easily become stout little generators just hanging out at the Pull-A-Part. And some of them are even kind of big, larger units for cooling larger pickups and SUVs.
My grandpa had a wind generator this size on his barn. Put a fan on a Model T generator so he could listen to his radio. The farm didn't have electricity. It put out 12 volts at 2 amps on a windy day. He made his own batteries too.
@@rosskstar cars are designed to get wet, you drive in rain? You probably couldn't submerge the motor. But downpour of rain could not effect the motor if it's sealed
One of the things that I like about your videos is the fact that you flat out enjoy what you do! Most of your videos seem to convey that without seeming acted out or scripted. Good show!
Years ago I was teaching in a remote school on a small island in the North Pacific. One of my students built a wind turbine much like this one, except he used a car alternator to generate the power and whittled 4-foot blades out of 2x4s. He mounted it on a 20-foot pole outside the school shop, and when word got round (tiny school) that he was ready to raise it we all turned out to watch. The best description I can give is "terrifying". That 8' span instantly took the sea wind and the thing just started wamp-wamp-wamping like it would eat the world. Chris finally managed to stop the blades by turning them out of the wind (which meant he had to get up on a ladder right behind those freakin' whirling broadswords and push on the vane), but the concept was well-proven. I don't remember how much electricity he banked in the battery during that maiden run, but all who witnessed it undoubtedly remain impressed by the sheer power he'd harnessed.
......the apprentices of BTH built one at the halls that they had outside Rugby, it had thin ply blades, which they perceived to getting close the the sound barrier.......the rain/hale of the storm delaminated it. These were the guys who also broadcast radio down the neutral and earth of the mains..
An improvement to this would be a dome shape on the end, so you can take advantage of the coanda effect to push some more wind to the widest parts of the blades. Also if you had rounded the ends out so they fit around the middle circle part + the dome on the end this would take the most advantage of coanda effect I think
I'm looking for ideas on self sustaining DIY things people can build at home and for there communities. Decided I wanted to make a wind turbine and this is the first video I clicked on. Just great! Really enjoyed it. Simple, Effective, Thank You!
Make like 10 of them using a Rose blade, various sizes down to a Rose Bud, and mount it on a windward wall. Paint them the color of flowers with different color patterns or different pinwheel patterns and colors. If it is too windy sometimes, add shrouds mounted separately that can automatically pop up in high winds and redirect some of the wind. Shape and paint the pop-up shrouds like giant leaves. The blades will still turn but shrouds will protect it from blowing apart. Just use a simple lever that has tension to hold shrouds down at low winds and high winds pry them up. Once wind goes down the shrouds go back in place. You can even design the shrouds to look like pedals that close and cover up the blade assembly.
Robert....thank you so very.very much for taking the time and sharing this build.....would never in a thousand years have thought of using a fan mother to make a wind turbine....so happy.....now I know how it’s done....thank you so much...Dave 👍
My son and I are learning arduino together, this windmill would be perfect for building and testing many things, like charge controller, wind speed indicator, as well as wireless communications to tell us when certain things are happening with the controller or generator etc. I have a number of automotive cooling fans, so I really enjoyed the video and the knowledge shared.
@@princessgreen726 I haven't built anything yet. Eventually I will have solar and wind, with a battery bank. The batteries will power the high demand appliances, wind and solar will charge the batteries when the major appliances don't run (ac/stove etc)
@@craynerd I believe he is talking about Marty T, you can put that into search and find him that way. I think he will have a video up this year on how one is built as I think he's helping a friend built one.
Rob, I love the idea, simple but very effective. May I recommend using grey soil pipe, the brown is for in ground use only as it does not like UV light, hence, it will fade and eventually crack if used outdoors. The grey will do the same job and can withstand the UV light. Keep up the great ideas.
I was going to say the exact same thing. UV light will kill the blades in a year. I would recommend painting with UV reflective paint. The hub also looks like PVC.
Marking the tubing with the cross on a bit of paper was genius, I'm enjoying watching your wind generator playlist on a lazy Sunday, very inspirational.
I expect the large blades to fatigue the original blades at the hub in a few hours of use. You also need to balance the prop to reduce induced vibration.
Mr. Murray-Smith, I like the way you think! Very handy! You get much faster rotation than I was expecting. I may in fact have to do this myself to power an LED light on my separate garage. All good wishes!
That's great! Now I'm looking at my ceiling fan that I'm about to replace and I'm thinking of turning that into a wind generator. Man, I'd love to hang out with you in your shop and just brainstorm and put stuff together. Thanks for putting this video together. Very informative and inspirational! Cheers!
Brilliant. And here I am with a new ceiling fan in a box to replace my old kitchen one. Now more excited to get the job done so I can experiment with the old one!
I have a few sheds and chicken coup that I heat and light now and then. Solar does the trick but this is so much cheaper and I have an almost constant breeze here. This will be for my patio and outdoor lights. Love this.
At about 2:25 what you are marking the lines along the length of the pipe, a extremely easy way to do that is to use a piece of angle iron or aluminum, lay the angle on the pipe so both open edges touch and scribe the line, perfectly straight. Size of the angle doesn’t matter, 1”x1” or 3/4”x2” they all work.
Two hints for drafting the lines out for cutting the pipe up. Got these from years of making high powered rockets. Wrap a strip of paper a few inches wide around the perimeter of the pipe, the exact width is not important. Wrap it around once tightly and cut it so it just overlaps and tape it, so you have a band around the pipe. Hold the pipe up in a door jamb and trace a straight line across the paper and cut it. Fold the paper exactly in half and crease it. Do it a second time. Wrap the paper back around the pipe and tape it. Now line one of the creases up in a door jamb and draft out that line. Do the same with the other three. This is pretty common for spacing rocket fins. How much power were you able to get out of it? I am guessing under 50W. Not bad if you can get the fan for free.
utterly BRILLIANT! I had to live in a tiny caravan for 10 years with only a petrol genny I could run to charge my battery a couple of these would have been more environmentally friendly AND quiet I am off to the scrappy!! Need to build some sort of charge controller next otherwise plugging that directly to a battery will just make it a FAN again!
Been going through all your videos from oldest to newest. this is the tech that got me interested in doing so and this is the video that motivated me to fix my youtube to allow me to join a channel for the first time. And now I'm a member :)
You just got to work on a pivot , a slip ring and a vain to direct it into the wind along with the relevant diodes and such to make it usable to store energy in a battery . Go on do part two please.
and naturally you could build your own custom battery &/or capacitor to store the energy. i'd bet you also have the skills/knowlege to build your own inverter for it too.
Great video, thanks Robert. Would be great to see new video of the energy produced, perhaps measure the voltage over a specific load. Seems to me that the fan is build for high rpm so would expect it to be small amount of energy generated in moderate wind.
What I love about this video is a real man making a real product. Most wouldn't even be able to hold that thing in the wind and if they did they'd probably lose their head. Cool video man
Nice idea. Now, my concern is, that probably the cheapest way to store the power, is using car batteries. But I put four of them in series, when I was 14, to make an arch welding setup. It operated intermittently successfully for perhaps a minute. However, during the high current discharge, the batteries had created very large quantities of hydrogen gas, which I didn't think of. Also, I had severely underestimated how thick the wiring needed to be. (I musn't ever have seen car jumper cables?!) The wires melted and somehow, some small spark was created, igniting the hydrogen gas outside and inside the the car batteries, causing two of of them to violently explode and hurling shattered batteryparts through the air, and presumably also acid. Perhaps luckily, I had my back turned at the explosion. In conclusion, I since then carry great respect and awareness of the dangers associated with car batteries. Indeed any high capacity battery. And I feel hesitant to build a huge powerbank with them. It would have to sit in another shack / building away from my house. And then I would still feel I lived close to a minor bomb.,
Nowadays there are LiFePo4 and LTO type batteries. That's a lot safer. Of course, a BMS is used here. And no, they are not really more expensive when you calculate the number of cycles and the service life. (Not to be confused with Li-Ion!)
Hi there, just a little something I learned while restoring old batteries. The extent of the battery exploding depends on the how much water is in your battery. The more water, the less cavity, and less gas build up. Hope this makes sense.... All the best.
Awesome. I heard about a gentleman who makes windmills that are strictly mechanical, he uses wind up flat springs that release their energy through a series of gears ⚙️ that make the turbine spin, he winds up the springs when there’s no wind
With respect, volts quoted without amps is meaningless. I can charge a 1 picofarad capacitor to 400 volts but it's gonna do absolutely nothing of any use.
The problem with using drainage pipe is UV. Being used underground it will not have the same UV protection as the polymers used in above ground plastics and will breakdown and become brittle which could shatter. Good project overall. :)
If you watched the whole video and had basic mechanical engineering knowledge you could easily follow his explanation and figure out anything you needed to do.
Robert, I wonder how it might work with a vertical drum style turbine? That would offer an omnidirectional presentation towards the wind without the need of slip rings or re-centring springs, wind vane and the need for counter weights and more critical levelling.... which would work well on a sailing boat... thoughts?
Thank you so much for this! I'm about to start a small research project focusing on small-scale wind turbines using common, available parts and your videos are so wonderfully helpful. Cheers!
direct drive washing machine and e bike motors (48v 1000w) are the ones that really produce a decent amount of power it has to be worth mounting the thing , on the other hand if one is just after charging 5v electronic devices this kind of blower motor mounted fairly low works okey , let me know if i can help
This vid was more enthralling than any pod race. Most adults have become unable to express delight because they've forgotten how or consider it beneath them. Keep the fire burning, subscribed 😎
Hi Robert, enjoyed it ! Seems, if you got 20 volts, it must be a brushless DC motor. That would really make a simple wind generator. Which auto manufacturers used those on their cars? Nissan? Most use a brushed DC motor, which won't produce power.
Nice concept, compliments! One mention, tough: the tips of the blades are perpendicular to the fan axis and if I'm right, those regions are not generating torque, instead are generating drag, isn't it? Maybe a bit more inclination on the blades would increase the efficiency and also help withstand better a roughly wind? What do you think? Thanks for the knowledge! Appreciated!
Great work 👍👍👍 QUESTION: Do I have to place the propeller to the opposite direction to the fan? i.e: wind has to hit the DC Motors clock or anti clock direction if the motor been used for Turbine?
yeah and there's so much improvement to be made to it...this has a lot of promise for a cheap solution. I think I'm going to try to 3d print the blades because I have this crazy strong crazy light weight carbon fiber filament.
I've used a drawer with the face edge corner to mark a straight line. For this you could clamp a 4' stick on the bench and put the tube against it to draw the straight line. Great video.
It would be interesting, to see how many short-circuit amps the generator could have produced, by setting the meter to amps, and connecting that across the terminals of the fan motor.(That would give some idea of the available torque of the new blades)
I would love to see a follow up video. I know that results would depend on the motor, wind speed etc. but I think it would still be very interesting. Thanks for sharing.
It has been a year or so. How is the auto radiator fan turbine mod getting on? Any improvements? Longevity? Did you make or store power to powerwall or batteries with it? Please make an update follow up video? Thanks for your ingenuity!
Great diy video! If I can suggest doing the wind test with a load, then a more useful power output number would be useful. The voltage by itself doesn't mean much without a load. Great idea on using pipe sections for windmill blades.
A car alternator needs over 3500 rpm to produce and I believe it needs a 12v input to make it work in the first place. There are ways of adapting one but you may as well buy the real thing if you're going to those lengths. A ceiling fan motor can work tho with magnets glued around the outer coils. There are videos on UA-cam on how to make them work
Great job. Although the speed at the tip probably exceeds the lift, and are thus probably creating drag. That is why blades made from pvc drain pipe are best tapered to a point and a low pitch cut on the leading edge to still create lift and cause less drag.
@@ThinkingandTinkering You gotta cut your own tips I guess. Lol. Sincerely though, Robert, I love your stuff, this is a great video. A very nice and accessible project. This and some Zinc Bro batteries and a fella could have some basic juice for pretty simple.
Hey Robert, was that DC fan motor a brushless type, or did it have graphite brushes? I think brushless would be preferred for wind machine use. Which manufacturer used brushless fan motors?
Robert, not all cars have a fan motor that will produce power. It must be a brushless type I believe. I found one on a VW, and taking it apart found graphite brushes. It can't produce power. Some (expensive?) cars have a DC brushless fan-motor, but which ones?
BREAKING NEWS: Man dies in freak accident involving soil pipe travelling at 70 miles per hour! Keep up the great work Robert. It would be interesting to quantify the difference that installation height makes to the efficiency of a wind turbine and that's an experiment I plan to undertake in the near future.
@@ThinkingandTinkering Yes, will do. My application is for wind power at festivals so height is expensive. I want to know where we get into diminishing returns. I read around the subject a bit, but always you the answer to go as high as possible, but with my curiosity, I want to dig deeper.
@@jamesharris5158 I would tend to think as long as you're above any nearby obstructions like buildings or tents that would be good enough. Above the tree line would be best, but for a portable installation that's kind of a ... _tall_ order.
20 volts at how many amps though. You need the amp measurements to calculate watts. The a dc to ac converter to step up the voltage at the expense of amps.
Or a DC to DC charge controller to charge a leisure battery. No need for an inverter if everything runs off 12 volts. You're 100% right about the amps produced at said voltage for anything really useful, I was hoping he'd have gave us that info at the end of the video too 👍
Exactly. Any nominal 12 V solar panel can create +20V open circuit too. The power it's able to generate varies with size of course. Put a load on it and watch the voltage drop. If the load is matched to the power rating of the source the voltage should stay stable at around 13-14 V or so. For example, a solar charge controller ensures that it only puts as much current into the batteries as it can while keeping the PV array voltage at around 14 V, enough to keep current flowing in the right direction.
Ok, I get it now. It is a wind powered generator. I clicked on expected a machine that generated wind. I was very keen to learn how a wind generator differed from a fan. In the end, not so much. It would be quite easy for me to spend a lot of time in your shop. Great stuff!
@@ThinkingandTinkering what you did here is no small thing. A graduate like me can see that, it can be made more efficient and also it gives people the idea that they can also make their own blades etc. It is not small thing that you did here... Well done.
@saladdogger You are wrong, I can make this thing ten times more efficient plus this is for confidence too to make your own stuff. His one makes 20 volts when the wind blows, I can make it efficient enough to generate 50 volts or more. Even with 20 volts, it can charge how many things overnight? Many.
Use black or grey soil pipe, they're designed for outdoor use and are resistant to ultra violet. I've seen the brown pipe discolour after being left outside and I suspect it will become brittle, like white non UVP pipe.
@@ThinkingandTinkering You mention the voltage it produces, but NOT the wattage, or even the rated wattage of the DC motor, which would be the max output achievable IF the device worked perfectly. I'm sure that you know that wattage (volts x amps )is power, not just volts. Before wasting time and money making one of these, myself and no doubt many others would really like to know what the practical power we could expect, and if you had just measured the amps after you'd done the volts (or given the motor's rating). Could you post this please, I'd like one for my off-grid weekend/holiday shack, but if it was only a few watts, it wouldn't be worth the bother. Otherwise, good video, thanks for posting.
Amperage? You mean the current? (In the UK). What he really needs to do is to attach a low resistance load across the output and measure the potential (volts) across it and/or the current (amps) going through it. Knowing both current through and the potential across the load (R=V / I) you can then calculate the power (in Watts) being generated (P=V x I).
Good presentation. I would like to suggest a modification of your design; do you think if you attached the hub to something that looked like a barrel which has vertical blades you wouldn’t have be concerned about wind direction or movable generator wire connections?
Actually the only reason for AC is because we can send it long distance without loss of voltage, through transformers every couple of kilometers... Tesla's benefactor and sponsor JP MORGAN wanted to get even richer... and Edison pushed direct current as safer... it's a lot less energy... and doesn't travel well... it requires local production... within a couple square kilometers... at the turn of the century in 1900 it meant coal fired electric plants... each hectare... prox... that's no longer true... locally made DC is absolutely dandy for household use... even air conditioning here in Arizona... where it is currently about 45° C outside... it's a very low temperature for this time of year... solar radiation is at max around the solstice... and it is sometimes as much as 50°... half way to the boiling point of water So I am going to install a cooling tower in my garage.... a tapered tube open at the top... I am going to put a wind powered turbine on top to push air into the tube... with a misting system at the top... its cooling causes air to sink.... and, through the existing air conditioning vents, a 12 volt exhaust fan can draw cool air through the entire house... I am starting with a cardboard tube .. and shellac to create a biodegradable bio plastic... I don't use denatured alcohol for the shellac... I use acetone... it's much more polar and creates a very hard, durable, bio plastic... I add AuPt dust... from volcanic ash... or any stream, creek, river or dry wash... it's absolutely ubiquitous, and not hard to find... it's slightly magnetic... and when you collect the sand from wherever water flows naturally... it can be separated out with a good magnet... it's the only gold stuff that sticks to a magnet... ya can't miss it... dry wet sand... and they separate much more readily... the taper creates a vacuum at the top, but whatever velocity it has is reduced by some factor of pi r² as a function of the diameter... so I will draw cool air through smaller tubes... and the greater pressure in the tapered tube is pulled through at a higher velocity... it's a function of the 2 diameters and the ambient air pressure Adding a small amount of AuPt to the plastic creates the double covalent bonds, I think only one double covalent bond... and it crystallizes the paper into a semi metallic crystal, which can be baked at a couple hundred degrees C... it's almost, almost like the first plastic called bakelite.... it's 5.5 on the Moh's scale of hardness... the same as stainless steel.... with my homemade paper... it's actually stronger than steel by a wide margin... because I use silk on the surface to create a smooth... incredibly strong bio plastic... and instead of trying to get rich... I give my ideas away as fast as I can.... the Universe gives back exactly what you put in... and a little bit more... I have no shortage of new ideas... mostly using existing technology
The use of fossil fuel is the only cause of global warming... and it is not our benevolent government's responsibility to ==>> give us ==>> different fuels... and I don't recommend holding your breath waiting for new fuels through government patents... those DO NOT "encourage new invention and technology"... it's exactly the opposite... it's very very expensive... it should not be done without a lawyer or two or three... and... if it looks like a viable technology... the cost of infrastructure to build whatever it is... usually comes from borrowing money. ... or money with strings attached... like old JP Morgan... and Nikola Tesla... and when you start making money.. they foreclose, or buy you out... and your nice invention... and your business then belongs to the money lenders... it's the same gawddamned money lenders mentioned by another teacher... it's not possible to borrow money from the oligarchs... and maintain a viable business... that's why very very few people get rich... quick or otherwise... it's always the offspring of other rich people who have access to funding without strings... it's a very very inbred group of people... they control all the resources of our lovely Planet... including, and especially, information Best bet... ==>> turn off the gawddamned television... it's not accurate information.... and they have controlled our Planet since long before the KT extinction event...

@@richardcarew4708 Hey! You've gotta be a chemical engineer of some sort. Me, I studied political science... so I guess I'll just have to buy my wind generator online.
Great video. 2 questions, firstly the blades look like they are tapered from base to tip. by how much? Secondly, did not get what you meant by the original blades being twisted and having to offset the three bolts.
Fabulous video. Simple and it does the job. I am sticking that in the mental tool box for when I get some time to fool around. Now to regulate the voltage. Thanks
There's tons of buck/boost or switching regulators of various sizes, voltage and current ratings that would resolve this issue, and many of them pretty cheap for this power level. Otherwise I would suggest learning how switching supplies and controllers work and maybe building something with a tl494 or a uc3843a.
Would I be right in thinking you could use a charging regulator sold for use between solar panels and a 'leisure-type' battery, with a similar amperage? Many alternative-power enthusiasts have one or two of those lying around.
When you were out here and the wind was blowing stuff across the ground, it looked like a normal September spring(or March Autumn) day here in southern Tasmania! 🤣 We haven’t had too much of that in the last few years though. Things are changing…
Dear Robert, Great video as always :). Quick question: as an avid fan of your work I would love to assist. I already support you through your membership program, but is there more I or others who feel the same can do to further aid you?
20volts is great ! but at what amperage?? will it put out a constant 5 - 10 amps?? if not it's just a experiment/toy, Im curious to know why you thinned the blades?? and also where they bolt onto the original blades of the fan, to keep a car battery charged the alternator can put out around a 100amps that is if the car battery is low after starting, much less normally If I use a 170ah 12volt deep cycle battery in a camper, I could charge it off the car in 15 minutes? in the morning, so is there enough current from this unit to charge a battery overnight? I'm very interested because my camper is nearly ready, and I need a power supply for the night time, days ok with solar panels. I would love to see you make one from a car alternator! much higher amps can be obtained I suspect.... great vid thanks for sharing 👍👍👍👍👍👍👍👍😁🍺🍺🍺 p.s I see below they talk of wind vanes and sliprings etc, I've seen here wind generators with Vertical blades and they don't need sliprings or movement of the generator, the vertical blades work from the wind from ANY direction!
The only work great if you can gear it down to a good enough level, the treadmill is like an alternator and only works best at higher rpm. You'll get some output at lower rpm but you won't be reaching anywhere near the potential of the device and will be wasting a lot of potential power.
Well , simple and it works. That same design repeatedly tested and the results are that it works. Now how to design a more efficient working model. Maybe start with the blades. Thanks for the vid.

Years ago I was teaching in a remote school on a small island in the North Pacific. One of my students built a wind turbine much like this one, except he used a car alternator to generate the power and whittled 4-foot blades out of 2x4s. He mounted it on a 20-foot pole outside the school shop, and when word got round (tiny school) that he was ready to raise it we all turned out to watch.
The best description I can give is "terrifying". That 8' span instantly took the sea wind and the thing just started wamp-wamp-wamping like it would eat the world. Chris finally managed to stop the blades by turning them out of the wind (which meant he had to get up on a ladder right behind those freakin' whirling broadswords and push on the vane), but the concept was well-proven. I don't remember how much electricity he banked in the battery during that maiden run, but all who witnessed it undoubtedly remain impressed by the sheer power he'd harnessed.
......the apprentices of BTH built one at the halls that they had outside Rugby, it had thin ply blades, which they perceived to getting close the the sound barrier.......the rain/hale of the storm delaminated it. These were the guys who also broadcast radio down the neutral and earth of the mains..
Beautiful description, thank you for the story!
Genuine Happiness when laughing,, You are true to YourSelf as to us,,
Take Care Sir
That was brilliant! Loved the simplicity of the build and the excellence of the presenter. Thank you 😊
An improvement to this would be a dome shape on the end, so you can take advantage of the coanda effect to push some more wind to the widest parts of the blades. Also if you had rounded the ends out so they fit around the middle circle part + the dome on the end this would take the most advantage of coanda effect I think
I'm looking for ideas on self sustaining DIY things people can build at home and for there communities. Decided I wanted to make a wind turbine and this is the first video I clicked on. Just great! Really enjoyed it. Simple, Effective, Thank You!
Make like 10 of them using a Rose blade, various sizes down to a Rose Bud, and mount it on a windward wall. Paint them the color of flowers with different color patterns or different pinwheel patterns and colors. If it is too windy sometimes, add shrouds mounted separately that can automatically pop up in high winds and redirect some of the wind. Shape and paint the pop-up shrouds like giant leaves. The blades will still turn but shrouds will protect it from blowing apart. Just use a simple lever that has tension to hold shrouds down at low winds and high winds pry them up. Once wind goes down the shrouds go back in place. You can even design the shrouds to look like pedals that close and cover up the blade assembly.
Plz make one & let us see. Thanks
Sounds so beautiful!!!!
It must be a good idea. Like a break system. However, I am having a hard time picturing it. Like Khondker said please make one.
Don't let aunt Ruth go smelling the flowers tho
Huh?
Robert....thank you so very.very much for taking the time and sharing this build.....would never in a thousand years have thought of using a fan mother to make a wind turbine....so happy.....now I know how it’s done....thank you so much...Dave 👍
My son and I are learning arduino together, this windmill would be perfect for building and testing many things, like charge controller, wind speed indicator, as well as wireless communications to tell us when certain things are happening with the controller or generator etc.
I have a number of automotive cooling fans, so I really enjoyed the video and the knowledge shared.
Hi Travis would like to know if what you are building can power a house and how many appliances
@@princessgreen726 I haven't built anything yet. Eventually I will have solar and wind, with a battery bank. The batteries will power the high demand appliances, wind and solar will charge the batteries when the major appliances don't run (ac/stove etc)
Each of your videos puts me back in shop class as a young man eagerly listening to the teacher give us lessons on mechanical fixes in daily life.
The simplicity exhibited here is fantastic! Thank you for sharing!
Maybe next video could be how to deal with the power it generates and the storage system; if you can.
there's a new zealander that also made hydroelectric from a stream. He uses a washing machine motor. on youtube.
@@dammitanothername can you post a link?
@@craynerd I believe he is talking about Marty T, you can put that into search and find him that way. I think he will have a video up this year on how one is built as I think he's helping a friend built one.
If the fan is fused with 40A in the car then the max power will not be greater than 40A x 12V = 480 Watts.
I agree. I’m pretty sharp but this is not my area and electricity is dangerous. It’s a mistake that nature won’t forgive me for lol.
Rob, I love the idea, simple but very effective. May I recommend using grey soil pipe, the brown is for in ground use only as it does not like UV light, hence, it will fade and eventually crack if used outdoors. The grey will do the same job and can withstand the UV light. Keep up the great ideas.
I was going to say the exact same thing. UV light will kill the blades in a year. I would recommend painting with UV reflective paint. The hub also looks like PVC.
Maybe a light coat of fiberglass to consolidate the entire "fan" together for strength (worried about the screws loosening) and weather protection.
The blades would be spinning so the UV Ray wouldn't be able to hit them...

@@philandhannahslittlefarm1464 Now that is funny!
Marking the tubing with the cross on a bit of paper was genius, I'm enjoying watching your wind generator playlist on a lazy Sunday, very inspirational.
I expect the large blades to fatigue the original blades at the hub in a few hours of use. You also need to balance the prop to reduce induced vibration.
Mr. Murray-Smith, I like the way you think! Very handy! You get much faster rotation than I was expecting. I may in fact have to do this myself to power an LED light on my separate garage. All good wishes!
glad you like it mate - cheers
That's great! Now I'm looking at my ceiling fan that I'm about to replace and I'm thinking of turning that into a wind generator.
Man, I'd love to hang out with you in your shop and just brainstorm and put stuff together.
Thanks for putting this video together. Very informative and inspirational! Cheers!
Brilliant. And here I am with a new ceiling fan in a box to replace my old kitchen one. Now more excited to get the job done so I can experiment with the old one!
@@eternallearner6026 did the ceiling fan work
I have a few sheds and chicken coup that I heat and light now and then. Solar does the trick but this is so much cheaper and I have an almost constant breeze here.
This will be for my patio and outdoor lights. Love this.
I did this almost exact same thing when i was younger. using a car fan motor. i used different blades though, yours are way bigger and work better.
cheers mate
thank you. I am going to build one this week for my off grid home. I have a parts vehicle with the fan already off! super exciting!
I would love to see a comparison of this vs a wind generator built on an alternator. watts, voltage, etc.
At about 2:25 what you are marking the lines along the length of the pipe, a extremely easy way to do that is to use a piece of angle iron or aluminum, lay the angle on the pipe so both open edges touch and scribe the line, perfectly straight. Size of the angle doesn’t matter, 1”x1” or 3/4”x2” they all work.
Im so happy to have found your channel, it’s truly a hidden gem.
I love your content and your enthusiasm towards your work.
Two hints for drafting the lines out for cutting the pipe up. Got these from years of making high powered rockets. Wrap a strip of paper a few inches wide around the perimeter of the pipe, the exact width is not important. Wrap it around once tightly and cut it so it just overlaps and tape it, so you have a band around the pipe. Hold the pipe up in a door jamb and trace a straight line across the paper and cut it. Fold the paper exactly in half and crease it. Do it a second time. Wrap the paper back around the pipe and tape it. Now line one of the creases up in a door jamb and draft out that line. Do the same with the other three. This is pretty common for spacing rocket fins. How much power were you able to get out of it? I am guessing under 50W. Not bad if you can get the fan for free.
Thank you Robert! I'm definitely going to use this with my off-grid home.
utterly BRILLIANT! I had to live in a tiny caravan for 10 years with only a petrol genny I could run to charge my battery a couple of these would have been more environmentally friendly AND quiet I am off to the scrappy!! Need to build some sort of charge controller next otherwise plugging that directly to a battery will just make it a FAN again!
I wish I had friends like this.
Me too
We are all friends here! Welcome!
Yeah.
Be the friend you want to have
A wish I had friends...
At all...
Been going through all your videos from oldest to newest. this is the tech that got me interested in doing so and this is the video that motivated me to fix my youtube to allow me to join a channel for the first time. And now I'm a member :)
You just got to work on a pivot , a slip ring and a vain to direct it into the wind along with the relevant diodes and such to make it usable to store energy in a battery .
Go on do part two please.
will do
Semaj - I'm thinking a rectifier and a grid tie. :)
and naturally you could build your own custom battery &/or capacitor to store the energy. i'd bet you also have the skills/knowlege to build your own inverter for it too.
@@geodeaholicm4889 IRC he said it was a dc motor so dc output?
@@ThinkingandTinkering what a cool idea I'd mount it to a caravan to keep the battery toped out ?
Great video, thanks Robert. Would be great to see new video of the energy produced, perhaps measure the voltage over a specific load. Seems to me that the fan is build for high rpm so would expect it to be small amount of energy generated in moderate wind.
What I love about this video is a real man making a real product. Most wouldn't even be able to hold that thing in the wind and if they did they'd probably lose their head. Cool video man
Nice idea. Now, my concern is, that probably the cheapest way to store the power, is using car batteries. But I put four of them in series, when I was 14, to make an arch welding setup. It operated intermittently successfully for perhaps a minute. However, during the high current discharge, the batteries had created very large quantities of hydrogen gas, which I didn't think of. Also, I had severely underestimated how thick the wiring needed to be. (I musn't ever have seen car jumper cables?!) The wires melted and somehow, some small spark was created, igniting the hydrogen gas outside and inside the the car batteries, causing two of of them to violently explode and hurling shattered batteryparts through the air, and presumably also acid. Perhaps luckily, I had my back turned at the explosion.
In conclusion, I since then carry great respect and awareness of the dangers associated with car batteries. Indeed any high capacity battery. And I feel hesitant to build a huge powerbank with them. It would have to sit in another shack / building away from my house. And then I would still feel I lived close to a minor bomb.,
Nowadays there are LiFePo4 and LTO type batteries. That's a lot safer. Of course, a BMS is used here. And no, they are not really more expensive when you calculate the number of cycles and the service life. (Not to be confused with Li-Ion!)
Hi there, just a little something I learned while restoring old batteries. The extent of the battery exploding depends on the how much water is in your battery. The more water, the less cavity, and less gas build up.
Hope this makes sense.... All the best.
I've made this style blade before for a school project... a little smaller but it works fantastic!
Inspiring!
Thanks for the video. Nice to hear you got up to 20 volts. What watts or amps did you get from it?
following
Awesome. I heard about a gentleman who makes windmills that are strictly mechanical, he uses wind up flat springs that release their energy through a series of gears ⚙️ that make the turbine spin, he winds up the springs when there’s no wind
With respect, volts quoted without amps is meaningless. I can charge a 1 picofarad capacitor to 400 volts but it's gonna do absolutely nothing of any use.
Yup. You can stick up a pointy object in the air and pick up kilovolts of static. Won't do anything tho
The problem with using drainage pipe is UV. Being used underground it will not have the same UV protection as the polymers used in above ground plastics and will breakdown and become brittle which could shatter. Good project overall. :)
I love the way you hide what you're doing and dont explain what you're doing. Best mystery story ever.
If you watched the whole video and had basic mechanical engineering knowledge you could easily follow his explanation and figure out anything you needed to do.
It must be a brushless DC motor to make any voltage/power !
This Man has this wonderful bundle of genius, generosity and joy. Just brilliant. Thank you.
Robert, I wonder how it might work with a vertical drum style turbine? That would offer an omnidirectional presentation towards the wind without the need of slip rings or re-centring springs, wind vane and the need for counter weights and more critical levelling.... which would work well on a sailing boat... thoughts?
if you get enough torque AND revolutions then any horizontal or vertical blade design works...
Amazing. most importantly your genuine smile makes others happy. thank you so much Sir.
Thank you so much for this! I'm about to start a small research project focusing on small-scale wind turbines using common, available parts and your videos are so wonderfully helpful. Cheers!
direct drive washing machine and e bike motors (48v 1000w) are the ones that really produce a decent amount of power it has to be worth mounting the thing , on the other hand if one is just after charging 5v electronic devices this kind of blower motor mounted fairly low works okey , let me know if i can help
Very cool stuff, just curious what sort of wattage you got or what the current was at 20v? Keep up the good work 😃
This vid was more enthralling than any pod race.
Most adults have become unable to express delight because they've forgotten how or consider it beneath them.
Keep the fire burning, subscribed 😎
Great video as usual. How many of those would it take to run a small refrigerator? A ballpark figure would be plenty good if it's not asking too much.
Hi Robert, enjoyed it ! Seems, if you got 20 volts, it must be a brushless DC motor. That would really make a simple wind generator. Which auto manufacturers used those on their cars? Nissan? Most use a brushed DC motor, which won't produce power.
Nice concept, compliments! One mention, tough: the tips of the blades are perpendicular to the fan axis and if I'm right, those regions are not generating torque, instead are generating drag, isn't it? Maybe a bit more inclination on the blades would increase the efficiency and also help withstand better a roughly wind? What do you think? Thanks for the knowledge! Appreciated!
Great work 👍👍👍
QUESTION: Do I have to place the propeller to the opposite direction to the fan? i.e: wind has to hit the DC Motors clock or anti clock direction if the motor been used for Turbine?
It was satisfying to see such a simple build working so well!
yeah and there's so much improvement to be made to it...this has a lot of promise for a cheap solution. I think I'm going to try to 3d print the blades because I have this crazy strong crazy light weight carbon fiber filament.
@@waynefilkins8394 As a fellow 3D printer I'm curious, how'd it go?
No way they are as strong as the pipe
I've used a drawer with the face edge corner to mark a straight line.
For this you could clamp a 4' stick on the bench and put the tube against it to draw the straight line.
Great video.
What a briliant idea
It would be interesting, to see how many short-circuit amps the generator could have produced, by setting the meter to amps, and connecting that across the terminals of the fan motor.(That would give some idea of the available torque of the new blades)
Any idea how many of these would be needed to build a charge station for a Tesla?
@@esperago I think at least 100
This is 100% the most useful video on this subject and I've scoured UA-cam for years
I would love to see a follow up video. I know that results would depend on the motor, wind speed etc. but I think it would still be very interesting. Thanks for sharing.
will do mate but might not be tomorrow lol
It has been a year or so. How is the auto radiator fan turbine mod getting on? Any improvements? Longevity? Did you make or store power to powerwall or batteries with it? Please make an update follow up video? Thanks for your ingenuity!
Great diy video! If I can suggest doing the wind test with a load, then a more useful power output number would be useful. The voltage by itself doesn't mean much without a load. Great idea on using pipe sections for windmill blades.
That's brilliant, I was thinking use a car alternator. But the fan motor is so simple.👍
A car alternator needs over 3500 rpm to produce and I believe it needs a 12v input to make it work in the first place. There are ways of adapting one but you may as well buy the real thing if you're going to those lengths. A ceiling fan motor can work tho with magnets glued around the outer coils. There are videos on UA-cam on how to make them work
having seen washing machine motors used i wondered about using the drum fixing vertical blades and driving motor that way!
Great job. Although the speed at the tip probably exceeds the lift, and are thus probably creating drag. That is why blades made from pvc drain pipe are best tapered to a point and a low pitch cut on the leading edge to still create lift and cause less drag.
Thanks for the tips!
@@ThinkingandTinkering You gotta cut your own tips I guess. Lol.
Sincerely though, Robert, I love your stuff, this is a great video. A very nice and accessible project. This and some Zinc Bro batteries and a fella could have some basic juice for pretty simple.
thats good info! thanks!
Can you suggest the best link/design for pvc blades?
Hey Robert, was that DC fan motor a brushless type, or did it have graphite brushes? I think brushless would be preferred for wind machine use. Which manufacturer used brushless fan motors?
Be sure to coat the white plastic portion to protect it from the elements. It will also aid it from stress cracking.
Robert, not all cars have a fan motor that will produce power. It must be a brushless type I believe. I found one on a VW, and taking it apart found graphite brushes. It can't produce power. Some (expensive?) cars have a DC brushless fan-motor, but which ones?
BREAKING NEWS: Man dies in freak accident involving soil pipe travelling at 70 miles per hour!
Keep up the great work Robert.
It would be interesting to quantify the difference that installation height makes to the efficiency of a wind turbine and that's an experiment I plan to undertake in the near future.
That would be labeled as a c0vid death
the higher the better, there is some wind currents at higher elevation.
that is awesome mate - keep me in touch will you?
@@ThinkingandTinkering Yes, will do.
My application is for wind power at festivals so height is expensive. I want to know where we get into diminishing returns. I read around the subject a bit, but always you the answer to go as high as possible, but with my curiosity, I want to dig deeper.
@@jamesharris5158 I would tend to think as long as you're above any nearby obstructions like buildings or tents that would be good enough. Above the tree line would be best, but for a portable installation that's kind of a ... _tall_ order.
20 volts at how many amps though. You need the amp measurements to calculate watts. The a dc to ac converter to step up the voltage at the expense of amps.
Or a DC to DC charge controller to charge a leisure battery. No need for an inverter if everything runs off 12 volts. You're 100% right about the amps produced at said voltage for anything really useful, I was hoping he'd have gave us that info at the end of the video too 👍
Exactly. Any nominal 12 V solar panel can create +20V open circuit too. The power it's able to generate varies with size of course. Put a load on it and watch the voltage drop. If the load is matched to the power rating of the source the voltage should stay stable at around 13-14 V or so. For example, a solar charge controller ensures that it only puts as much current into the batteries as it can while keeping the PV array voltage at around 14 V, enough to keep current flowing in the right direction.
Ok, I get it now. It is a wind powered generator. I clicked on expected a machine that generated wind. I was very keen to learn how a wind generator differed from a fan. In the end, not so much.
It would be quite easy for me to spend a lot of time in your shop. Great stuff!
I love your energy you are like my electronics teacher back in highschool haha
6:00 Cardboard box blown past in the opposite direction to where the generator is pointed. Awesome!
That’s quite some wind! The box in the background adds to the effect.

@bullsballs you need to be able to apply brakes to it somehow, storms come around quite often
@@ThinkingandTinkering what you did here is no small thing. A graduate like me can see that, it can be made more efficient and also it gives people the idea that they can also make their own blades etc. It is not small thing that you did here... Well done.
@saladdogger You are wrong, I can make this thing ten times more efficient plus this is for confidence too to make your own stuff. His one makes 20 volts when the wind blows, I can make it efficient enough to generate 50 volts or more. Even with 20 volts, it can charge how many things overnight? Many.
Hi, very cool. Should the motor drive around the opposite way to the original intended rotation? Thanks
Congrats from Argentina Robert. Your videos are great, full of intetesting stuff.
Awesome, thank you!
Use black or grey soil pipe, they're designed for outdoor use and are resistant to ultra violet. I've seen the brown pipe discolour after being left outside and I suspect it will become brittle, like white non UVP pipe.
just brilliant..it really spun up, this is absolutely a project I'm going to experiment with.
i know it - it was awesome lol - keep me in touch mate
Brilliant idea. Using this to charge up a 12v leisure battery which could then power 5v devices like phones, speakers etc would be awesome.
@@ThinkingandTinkering You mention the voltage it produces, but NOT the wattage, or even the rated wattage of the DC motor, which would be the max output achievable IF the device worked perfectly. I'm sure that you know that wattage (volts x amps )is power, not just volts.
Before wasting time and money making one of these, myself and no doubt many others would really like to know what the practical power we could expect, and if you had just measured the amps after you'd done the volts (or given the motor's rating).
Could you post this please, I'd like one for my off-grid weekend/holiday shack, but if it was only a few watts, it wouldn't be worth the bother.
Otherwise, good video, thanks for posting.
Good for recharging lithiums for the vibrators and such toys. Probably save you $400-$500 yearly in electricity.
GREAT VIDEO!!! GREAT JOB!!!!!
I'd love to know the amperage readings.
Sadly, he almost never gives useful numbers. Volts *and* amps, etc. At least in previous vids and projects.
Amperage? You mean the current? (In the UK).
What he really needs to do is to attach a low resistance load across the output and measure the potential (volts) across it and/or the current (amps) going through it.
Knowing both current through and the potential across the load (R=V / I) you can then calculate the power (in Watts) being generated (P=V x I).
It's a lot lower than you think.
Good presentation. I would like to suggest a modification of your design; do you think if you attached the hub to something that looked like a barrel which has vertical blades you wouldn’t have be concerned about wind direction or movable generator wire connections?
Perfect for your all your post-apocalyptic power needs.
Actually the only reason for AC is because we can send it long distance without loss of voltage, through transformers every couple of kilometers... Tesla's benefactor and sponsor JP MORGAN wanted to get even richer... and Edison pushed direct current as safer... it's a lot less energy... and doesn't travel well... it requires local production... within a couple square kilometers... at the turn of the century in 1900 it meant coal fired electric plants... each hectare... prox... that's no longer true... locally made DC is absolutely dandy for household use... even air conditioning here in Arizona... where it is currently about 45° C outside... it's a very low temperature for this time of year... solar radiation is at max around the solstice... and it is sometimes as much as 50°... half way to the boiling point of water
So I am going to install a cooling tower in my garage.... a tapered tube open at the top... I am going to put a wind powered turbine on top to push air into the tube... with a misting system at the top... its cooling causes air to sink.... and, through the existing air conditioning vents, a 12 volt exhaust fan can draw cool air through the entire house... I am starting with a cardboard tube .. and shellac to create a biodegradable bio plastic... I don't use denatured alcohol for the shellac... I use acetone... it's much more polar and creates a very hard, durable, bio plastic... I add AuPt dust... from volcanic ash... or any stream, creek, river or dry wash... it's absolutely ubiquitous, and not hard to find... it's slightly magnetic... and when you collect the sand from wherever water flows naturally... it can be separated out with a good magnet... it's the only gold stuff that sticks to a magnet... ya can't miss it... dry wet sand... and they separate much more readily... the taper creates a vacuum at the top, but whatever velocity it has is reduced by some factor of pi r² as a function of the diameter... so I will draw cool air through smaller tubes... and the greater pressure in the tapered tube is pulled through at a higher velocity... it's a function of the 2 diameters and the ambient air pressure
Adding a small amount of AuPt to the plastic creates the double covalent bonds, I think only one double covalent bond... and it crystallizes the paper into a semi metallic crystal, which can be baked at a couple hundred degrees C... it's almost, almost like the first plastic called bakelite.... it's 5.5 on the Moh's scale of hardness... the same as stainless steel.... with my homemade paper... it's actually stronger than steel by a wide margin... because I use silk on the surface to create a smooth... incredibly strong bio plastic... and instead of trying to get rich... I give my ideas away as fast as I can.... the Universe gives back exactly what you put in... and a little bit more... I have no shortage of new ideas... mostly using existing technology
The use of fossil fuel is the only cause of global warming... and it is not our benevolent government's responsibility to ==>> give us ==>> different fuels... and I don't recommend holding your breath waiting for new fuels through government patents... those DO NOT "encourage new invention and technology"... it's exactly the opposite... it's very very expensive... it should not be done without a lawyer or two or three... and... if it looks like a viable technology... the cost of infrastructure to build whatever it is... usually comes from borrowing money. ... or money with strings attached... like old JP Morgan... and Nikola Tesla... and when you start making money.. they foreclose, or buy you out... and your nice invention... and your business then belongs to the money lenders... it's the same gawddamned money lenders mentioned by another teacher... it's not possible to borrow money from the oligarchs... and maintain a viable business... that's why very very few people get rich... quick or otherwise... it's always the offspring of other rich people who have access to funding without strings... it's a very very inbred group of people... they control all the resources of our lovely Planet... including, and especially, information

Question... Is there a DIY voltage regulator/charger we can hook up to this for then connecting to a battery array?
loads on the net mate
There's tons of buck/boost or switching regulators of various sizes, voltage and current ratings that would resolve this issue, and many of them pretty cheap for this power level. Otherwise I would suggest learning how switching supplies and controllers work and maybe building something with a tl494 or a uc3843a.
Would I be right in thinking you could use a charging regulator sold for use between solar panels and a 'leisure-type' battery, with a similar amperage? Many alternative-power enthusiasts have one or two of those lying around.
When you were out here and the wind was blowing stuff across the ground, it looked like a normal September spring(or March Autumn) day here in southern Tasmania! 🤣 We haven’t had too much of that in the last few years though. Things are changing…
Dear Robert, Great video as always :). Quick question: as an avid fan of your work I would love to assist. I already support you through your membership program, but is there more I or others who feel the same can do to further aid you?
If you lived near mate you would be welcome to come in and work with me
@@ThinkingandTinkering As lovely as that would be, sadly I'm half a world away in Seattle, Wa. United States :(
shame mate
20volts is great ! but at what amperage?? will it put out a constant 5 - 10 amps?? if not it's just a experiment/toy,
Im curious to know why you thinned the blades?? and also where they bolt onto the original blades of the fan,
to keep a car battery charged the alternator can put out around a 100amps that is if the car battery is low after starting, much less normally
If I use a 170ah 12volt deep cycle battery in a camper, I could charge it off the car in 15 minutes? in the morning,
so is there enough current from this unit to charge a battery overnight?
I'm very interested because my camper is nearly ready, and I need a power supply for the night time, days ok with solar panels.
I would love to see you make one from a car alternator! much higher amps can be obtained I suspect....
great vid thanks for sharing 👍👍👍👍👍👍👍👍😁🍺🍺🍺
p.s I see below they talk of wind vanes and sliprings etc, I've seen here wind generators with Vertical blades and they don't need sliprings or movement of the generator, the vertical blades work from the wind from ANY direction!
Great video as always Robert! I remember reading somewhere that motors from Exercise Treadmills make excellent wind generators.
they do indeed - i wonder - i have a starter motor - they are similar - must look at that - thanks for the idea
The only work great if you can gear it down to a good enough level, the treadmill is like an alternator and only works best at higher rpm. You'll get some output at lower rpm but you won't be reaching anywhere near the potential of the device and will be wasting a lot of potential power.
You need a really big fan to spin something like that. AND a lot of wind.
Thank you for sharing this. Buying a small camping lot and intend to have a marine battery charging for cell charging and lighting.
You looked like you were having fun! Thank you for posting 🙏💖
Very good. Whar about long time exposure to strong wind? Could the blades shatter from fatigue after some time?
And yes i absolutely loved the video, & I'd a never thought of using an ol car cooling fan motor, brilliant
Well , simple and it works. That same design repeatedly tested and the results are that it works. Now how to design a more efficient working model. Maybe start with the blades. Thanks for the vid.
