I'm uploading 2 videos of the 3 long blade version that I just got home with, connected my meter to the plug pins and got an awesome result, I then added a rectifier and recorded the voltage in DC
I'll jump over and see - thanks for the heads up mate
@@ThinkingandTinkering Think a little harder about the mechanics & physics underpaying your proposal.. with you're hold is akin to a paddle steamers wheel.. step back & look at it again vs a turbochargers "impeller" & the "turbine" wheel of a turbo.. next think about your argument of the alternator vs permanent magnet rotors.. of course you'll get a MUCH big charge as the field coil cores & rotor magnets/coil dia's increases.. the rate/voltage of charge created is an exponential factor of the speed of the magnetic field cut passing the field coils.. neodymium magnet rotor around a Gentle Annie armature is as cheap as you're ever going to get.. back to you paddle wheel with ALL that air flow direction reversals .. a POOR POOR design in physics & aerodynamics.. TOO MUCH energy lost in flow changes.. duct it like a turbocharge exh turbine wheel.. on top of an inverted hollow exhaust mast
@@ThinkingandTinkering what if you used the geo spin design the astronauts use for zero spin training? If you replaced the bars with deep curve blades it would be like combing vertical and horizontal turbines together. You'd also have 3 center points so you could have 3 or 6 generators on one setup,it would collect wind from every direction,it would always be balanced even in a tornado and being a complete sphere it would be less likely for birds to fly into it because it's not just a blurry flat surface.
Great ! Thank you!
The Savonius-Rotor is easy to make , very cost effective, works very well with any wind direction.
I tried many others, but - many little Savonius Units are the best.
Cheers!
Rob, I read one of the earlier comments (from Rock Lover) and I can't stop thinking about it. Would be great if you could offer some feedback as, to me anyway, it's very clever thinking.....his idea of having an inner shaft split into two sections (where with one 'tube' revolves inside the other) would allow you to connect a set of vertical blades to each one....if each blade set revolved in opposite directions the result would be that the magnets and coils would be passing each other at twice the speed but utilising the same force of wind.....surely double the output for the same effort. Apologies to Rock Lover for repeating his idea but simply hoping you got twice the opportunity to get Rob's attention/thoughts. 👍
I found the builders board popped up when I called it utility board. Builders board brought up all sorts of cement boards and the like.. Hope this helps anyone trying to find it.. Great Video Rob (as per normal)
Great, could put a fan motor top and bottom. Though the alternating current my be off a cycle...I guess a low power diode set up would allow a power doubling?
My thoughts too, but when rectified to DC and adding a capacitor the issue may be resolved
Aerodynamic drag type turbines have a tip speed ratio less than 1, and contrast with aerodynamic lift type turbines with a tip speed ratio greater than 1, and tip speed says alot about rpms in a given wind. And motors/generators are rated to a specific rpm per volt and amp.
All That said, a particular motor with a high rpm per volt does not pair well directly drive to a drag type turbine. Ratherly, gearing may be preferred over direct drive or to use a lift turbine.
But there's trick to design drag type VAWT turbine to spin a bit faster. The radial velocity will be the tip speed ratio × wind speed which sugest that by decreasing the radius of the sweep area while maintaining a constant radial velocity will increase the turbine's rpm. Because RPM=radial velicity/2×3.141×radius when the radial velocity is adjusted to distance/minutes. But to maintaine the same cross section of wind, if you half the radius you'll want to double the height in order to catch the same amount of wind.
Very interesting
I liked the bit where you talked about wind turbines 🌬⚡love the channel =)
You should try your rose fan on it and see if that works better.
I got the 6 blade version and tried it with 3 of your soil pipe aerofoil propeller blades that are about 50 cm long. It was giving me about 80v and about 0.02A short circuited. I decided to hook this up to a small transformer that I salvaged from a UPS followed by one of those rectifiers. Output was not bad I measured 16v 0.1ma. I was disappointed with only 1 Watt but that seems to be a pattern with my home made wind projects.
What would be interesting is if you can come up with a more sturdy mount for the coils/shaft. This felt like the shaft was gonna snap in my hand and still generated nothing.
I was thinking the same about strain on the main shaft, I’d be tempted to build a larger vertical turbine with a fan motor on both ends to reduce the strain
@@Milkybar3320011 the faster it spins the more volts it produces, it doesn’t seem to increase current very much so it really needs some kind of mini transformer. I’d like to test it on a proper single phase wind charge controller that can regulate the output for a 12v lead acid. I suspect 2 motors will produce closer to what is required so I think u have the right idea. My next test is going to be a cable drum with guttering as the blades. Gonna try one of Robs water bearings and hope most of the load is on that rather than the plastic shaft. Maybe some sort of belt drive would also ease the stress and increase rpm.
great content thanks
Absolutely awesome! Those ring magnets in direct drive motors found in more modern washers looks like a good start. 👍🏻
The single coil is paramount! Outstanding! I am longing to try this with a N. Tesla turbine and some steam from the garbage pyrolyzer I am also dreaming of building. As soon as my other jobs have let up. In about 20 years. After I can retire. Retire?! Ha! What ever makes me think that? First I need to build me a set of properly fitting chairs. That could take another decade.
I wonder if you can combine this fan with one of those vent fans from the tops of houses. Those can catch wind from any direction and are premade.
it's basically the same as them, low efficiency but cheap as chips. Get vent fan and add generator.
@@thekaxmax seems like a good upgrade. plus, the generator design is so simple, someone could replicate it with a more worthwhile out put
@@johnnyhellfire6 There's only so much energy you can get from a given cross-section and wind speed. A single spinner isn't going to give you much without a continuous gale. Although adding an upwind concentrator (funnel) may help. But we're getting out of cheapness now--low energy or cheap, pick one.
@@thekaxmax every little bit counts
@@thekaxmax every little bit helps
Well done! I bet these would work well for micro-hydro power. One more Fall project I probably won’t get too.
Keeping the AC output dry will be important
Now this is getting SO interesting, keep it up Rob, love the Vids !
loving your vids just built a small solar charging for my shed very interested in adding a wind turbine to the mix
Interesting, as a contractor in the States I’ve never head the term “center board” referring to that material. We call it soffit where I am. 👍
Love this channel, thank you Robert
I love your ideas and videos especially around windenergy
maybe a reclassification of turbine types is needed -Axial and Transverse -(relating to wind path relative to generator axis) as a VAWT can be mounted in any orientation - even arrayed about a "central axis" - if one were to wish - they can even be tracked as well as located on permanently located structures - if one wishes to use suboptimal locations or overly complex designs... all for fun and exploring different options.
Amazing….I had a similar idea whilst walking the beach in a storm a couple of years ago! ❤
Adding partial fins Short and small, at the edge, that only are from edge 20%in on radius on base. Spaced 45 degrees to the main fins making fin total 6, adds more torque. These little partial fins also improve start from dead. I 3D printed this, improving start and torque about 50%, even though they were 15% size of 2 main fins. If you build ends with slots for magnets and support bearing plates with coils in, generator. That is if one spins their their coils, for project
I ordered two of the fans yesterday, looking to build a VAWT with them. Excellent timing, Rob!
If you don't mind sharing. Where did you order them from? I ask, as I couldn't find any after searching...
@@robbie.robertson I like to purchase on wish or eBay mostly there are declared as portable fans
@@mistersync100 Many thanks, appreciate it... I'll check Wish out first, as I'd already looked at eBay and not spotted them.
Same here - would love to grab a few of these but can't find any link!
Searched both Wish and eBay, and I can only find them at around £15 (including postage). Shame, to much for me to have a play with :o(
Ring magnet, brushless design is something that's good, one suggestion for your rotor, if you visualize water falling onto your rotor there is no where for it to pile up it will shoot over to the other side, however with a PVC sink drain tube in the middle to block the cross flow would allow for a pile up so to say of the Wind for each blade not affecting the other side negatively, there are several ways to utilize cross flow but it looks like one simple addition might improve it?
I love all your ideas. I envision harvesting power from many sources. Can you advise how to combine all the 'trickles' of currents at different voltages into a 'river' of power to feed into a power station for storage?
A thought, inspired from another comment about stacked counter-rotation Savonius idea ( will try to re-find it later to give credit where it's due )
I'm liking the idea of rotating the coil and magnetic fields in opposite direction, which makes me think you'll get usable energy at lower windspeeds .
My thoughts are, rather than stack them, to explore making a device that has a Savonius type interior rotating one way and a Darrieus ( egg-beater ) outer rotating in the counter direction. Of course the airflow of the outer will disturb the inner airflow so couldn't expect the efficiency of 2 independent devices but it would be interesting to see if it could boost the extraction from a similar surface area of either independently.
It has further occurred to me, that rather than spin the coil, which brings in the need for slip rings and added points of failure, would it create the same effect by just spinning the crab cage ( in opposite direction to the magnet ) around the coil? The 2 parts of that could be joined together with something non magnetic like resin/fibreglass
There were savonius rotors that were built from oil drums, they made a lot of power! The issue with building the rotor to be dependant on the generator bearing is that those bearings usually are the point of failure.
Initially I thought you were going to make your version of the Aeromine wind turbine. Might be worth looking in to? (check NewAtlas)
Drive the generator from the edge of the disks. You'll get several turns of the generator from each revolution of the disk. If it spins easily enough, add a second generator.
Good idea! What about using a stack of them--wired in parallel--to multiply the power? They are each so short that you could probably fit at least a half-dozen between the two disks.
But If you drive the generator from the edge of the disk, you get less leverage. Wouldn't the resistance of the generator applied to the edge of the disk cancel out what benefits of gear ratio that you might get from such a configuration?
@@Berkana It's hard to say, but I would think that with the pitiful amount of wattage that particular generator put out, it shouldn't have that much resistance. Of course, adjustments will be needed for optimum performance.
A cheap solar panel would be better.
@@irishguy200007 No doubt, but I think we're working on something from parts-on-hand type of situation, as he often does. Actually, wind is very indirect solar power if you think about it...
A savinous wind turbine with the axle being the generator where the magnets rotate with a stack of coils on the inside 🤔
There's also an interesting way of wind proofing a vertical turbine by folding the layers into themselves with servo motors making a round column whenever wind speed is too high automatically and self powered.
Brilliant Bob, looking forward to a cheap upscaled model.
Great video 👍 was thinking that fan design with multiple shorter fins might work great on a water wheel, especially on a extended wall unit 👍
I was just thinking of making a long version, dropping across my stream with some bike chains to gear the speed up and then see what come out the other end power wise...
Awesome! And looks quite nice 👏
I love the idea of the helix capture design. I'm struggling to make one though..
Maybe you can put two of those generators on each turbine section, one on each side. Double the amperage then maybe put a stack of five or ten turbines with double stacked generators on each one you could have up to 20 times the amperage output. I think by improving on the type of turbine oh, you have many ways of increasing the output and using this ring magnet coil with Armature setup for a generator, a benefit is that it is brushless. A little waterproofing, if you had a small stream or river near your property, you could put multiple units up and down the bank of the river. A water wheel design could be used.
And it could be triboelectric too yeah ?
A triboelectric stethoscope would be amazing. Haven't seen that
Thanks for saving the world everyday Rob
Robert, could you make a Ugrinsky turbine version of this and see how it compares to the Savonius turbine version? I'm curious to see a practical comparison of the two designs.
I think this is the first time I've ever heard a Jonathan Swift reference while learning about wind energy.
For a wind wall I think a stepper motor in the mittle driven from bicycle gears and a chain would maybe be the more efficient solution even with the friction losses counted in.
Maybe 2 metres top to bottom 160mm halve pipes would work also as these cover more area with less fiddling 120 degree offsetting could be done by the next collum and so on. We can buy those 160mm 2m long pipes for €14 here in Germany.
If you stacked a couple of them on top of each other like you did with the wind wall (to make a single tower could you make a Venturi case that turned into the wind to help increase air flow?
Could work. I know there is a Canadian company essentially planning the horizontal version of that for on top of house roofs. they seem to generate power like mad.
Perhaps this would do well with
The Rosebud?!
Thank you Robert!!
These little turbines could well prove very useful!!
And add towards getting off-grid!!
Thank you, as always,for inspiring, encouraging and teaching us all.
Namaste. ...XxX...
just watched you smash the other one aqart and now this whoop. crazy how simple that motor is. thinking if you wound thicker wire on the windings would that increase tourqe and or gather rate?
For cheap and easy to make as well as durable, look into wind belts.
I think it would be nice if you could link the previous videos you make reference to, in the description or pinned comments of your videos. It would make it easier to follow your threads 😎 You are a fun educator 😊 Keep'em Coming Boss 🤝🫡
What about a wind sail that uses leverage and catches all the force. Of course it would heve to have interruptedwind to recover. Perhaps a design like your simple mode to accomplish this? Wind sail catching the entire surface would be a tremendous amout of leverage.
Would a baffle or cone directed to one side of this turbine improve efficiency? The wind would hit the right side of the turbine rather than both sides and if mounted to a larger plastic surround it could pivot with a vane into the wind. The only problem I see is that the wires for the turbine would have to run through the inside of the shaft so the baffle can rotate 360 degrees with the wind direction.
I'm wondering. Could you build a horizontal axis unit that roof mounts on your car in the vortex area just behind the windscreen. Theoretically not adding to the drag coefficient, because it's in the low pressure zone vortex, you could keep raising it slightly until it catches the air stream above the low pressure zone. Not the large diameter unit you show there. Something say 3" diameter with a length from drip rail to drip rail. And would it be enough to recharge the battery in order to remove the parasitic load of the alternator? A tremendous undertaking, to be sure! If nothing else, I'd like to see an experiment with one mounted on a board that you could measure the outputs according to the angle of the board against a steady wind, as the air would have to ramp up the board creating perhaps a higher pressure, while also creating the low pressure behind it that the Savonius could dump its "spent" air into. Well, creating a higher and lower pressure in front and behind, respectively, anyway!
hi, from Barbados, i caught your video researching ideas to power my whole home by use of wind. watching this, I'm thinking use a lazy Suzan between fan and turbine allowing fan to stand still while turbine spins.
i'm interested in the turbine wall, and how best to make an effective wall to power my entire household.
Could this setup and your figures you stated be powerful enough to charge 12 volt batteries?
I know nothing much about electrics, but for 12 v led lights run off batteries charged (if it works) by wind is worth giving a go....... 👍🏻
Could you add a capacitor to the led to stop the flashing and get better results?
Can’t remember if the output AC, but if it is DC or you add a simple bridge rectifier then a capacitor I believe would help
I wonder, how would it perform in higher winds speeds?
Oh thinking about making some of these for my boat.
original Daymak e-bike rims with the larger center rims are the best for wind turbines. they make the hubs smaller now.
So interesting and inspiring. Thank you.
One question, if we had a means to generate more torque to the generator, how could we use that to increase the energy output of the generator? It appears the alternator type generators are more effective at speed. Thanks!
It would be interesting to see the crab claws held together by a magnet (like a flywheel) and running over the coil to induce the field
Your intro - “I’ll take your brain to another dimension, pay close attention”?
Another exciting video giving us hope from the lovable genius
lol - wow - cheers mate
I never understood why every house didn't have 10+ of these along the ridge of their roof. Sure it would need proper noise and balancing and maintenance, but they seem very viable combined with some solar panels.
Cutting another large hole on top, and affixing another generator on the other side might be interesting.
That's more like it, well done sir. $10 each, with some improvements on the output, you got a portable phone charger
I will be impressed if you make a wind generator with flexible wings that can spill wind if the wind gets too strong.
I’ve seen a few pole mounts that tilt in high winds to reduce turbine speed in high winds too
Please document the energy consumption of the source blower. I’d expect your energy capture ratio to be > 1/10 of input. How about changing the gutter surface from smooth to soft. This design also disrupts the wind flow, a tiny jet of compressed air might prove to be more efficient to test but will never be realistic compared to actual wind. Such is the dynamic world of entropy, enjoyed the video.
It would be interesting to see how this would compare to that same size turbine in the Ugrinsky configuration. Theoretically it should be 48% better.
Look into Harmony (USA) vertical wind turbines. ‘They are designed from the bottom up’
If you were to extend the wall out from the U shape to create more of a pocket, sort of like a hallow ying yang with a deep pocket on either side; do you think the efficiency would improve?
I would think you'd have more focused wind into the system, and less drag around the outside as it would look like a closed circle, with two openings for the air to enter on either side as it spins. Just curious if you've tried it.
Hard to explain it with words. Too bad you can't include basic diagrams on UA-cam.😉
Better! TY!
Thank you
A HAWT will always out-perform a VAWT because the prop is essentially a wing where a turbine catcher has too much drag. I did some experimenting with small wind power, hoping to develop a cheap residential power system. In the end, solar far out-performs wind but the downside is that Earth has nighttime, where we consiume power for lighting. Battery storage is the balancing point and, as better batteries become inexpensive, solar will always win. Mr Sun gives out a huge amount of free energy.
no it won't - try a hawt in a built up area
@@ThinkingandTinkering You right Rob! and with an greater area higher speed! But an easy solution with higher quality we got a safer system we can trust in!
Wow, amazing. Think of actually being able to power an LED!
this little generator looks to be a great micro micro hydro generator or gravity generator. could the Savonius wind turbine design be adjusted to work as a under flow water wheel? could you make the Savonius turbine out of tin so you could use the rocket stove exhaust to spin it?
All considered Fluid dynamics - I would not advise using a fan in the exhaust of the stove as a way to capture energy .. the restriction and buildup of soot would be detrimental to the function of the stove - safer to just boil water on the stove and making a steam generator
a shroud blocking the upwind side that rotates with the wind would increase efficiency and power.
Does the number of blades on a horizontal wind turbine increase the performance? If so, if you cut the guttering down lengthwise you'd have 4 blades instead of 2. It would be interesting if there was a source of similar fans/motors in the UK.
When the output is loaded what size of blade will you need to overcome starting torque? My next door neighbor loves building windmills to power garden lights. But his biggest problem is that unloaded they turn ok but as soon as they are loaded they just standstill as the wind can’t overcome the torque imposed by a few rechargeable batteries. And we are not talking large batteries just enough AAA cells to run the lights over night.
Robert did a video a while ago about cogging (I think that’s the phrase) he added a small capacitor, which allowed a the turbine to spin up first
@@Milkybar3320011 A small cap won't that limit the output current and thus power.
I think it needs something like a gear box, in reverse so it can start in 4th less torque load and then work up to 1st.
The only other thing i can think of is a form of output control which brings in the load once the blades have some energy behind them.
Do you have a video deeply explaining how an alternator works and how to use it as a generator?
Robert has previously done a video on this, I’m sure one of the other viewers will know which video and let you know
agree with another comment, is coil wire too slim and really hindering output?
agree with you about the basic alternator being a great candidate to exploit because manufacturing costs would be near nothing. I liked your converted roof exhaust unit a lot and same for the large squirrel cage turned VAWT.
I watch your video's and I am amazed at how easy you turn one thing into a completely different product. Have you thought of doing video's for young children to get them to experiment at home under the supervision of course of their parents or guardian.
So if you put one fan motor at either end of end of each savonious section of the wind wall this could do quite well? It's always windy up here where we are, hence why the energy companies planned a load of larger scale turbines up here. I really think a combination of with d and solar up here could get us off the energy nipple once and for all, it's just affording the storage solutions for the generators.
On the point of a wind wall , I can't work out how the generators (alternators) are connected in parallel , since they have slightly different output , even if they are from the same manufacturer and with same nominal properties. I mean , slight differences in output of generators on the same wind wall , will create difference in electrical tension (voltage) , which will cause heating of the common conductor(wires) , that connects all of the generators in the same wind wall. Or , is there a need for a voltage regulator on the output side of each one , before they are connected to common output conductor ?
I suspect the rectifying to DC with a capacitor may be part of the solution. There’s going to be genius viewer on here with the solution and parts list lol
@@Milkybar3320011 Thanks , I have (kind of) suspected that and it is just annoying to me , because it means either more wires , or building a weather proof box for electronics. It is easy enough (not very expensive too) to find right electronic components for that , but I hate spending money on a , basically , hobby experiment. Well , such is a life :) I'll probably go with more wires , in some kind of conduit (I prefer AC trough conductor to the electronic/power box).
I love your show.! Hope i gave you a good idea to try out. Your quite the tinkering typ. Have you patented anything. Its can be a difficult process id imagine. Ive had a couple of ideas that actually made others lots of money. Ideas dont mean much unless they are developed and cost effective. Let me know what you think if you have time or care to. Thanks again for your videos.
Damit könnte man Dächer, Gärten, Zäune und Balkone ausstatten.
I might have missed this while going through his other wind wall videos, but why did he move away from the nema motors? Were they less efficent or is he trying to find the cheapest option?
Hi Rob, have you seen Disruptive Inventions and their recent interview with Harmony Turbines? Two key inventions worth viewing.
I haven't seen the interview but I know harmony
@@ThinkingandTinkering Apols, it's Disruptive Investing, not Inventions.
I'm going to be building something similar as an add on to my off grid system. I'm not a big fan of the fan. LOL
The savonious will have less rpm, more torque. Shield half of it to bring up the tsr to over 2.0
You call it "alternator style". All semi serious wind turbines have alternators. The ones that have generators (dc) use brushes, which require much maintenance. These are not used very much at all.
Great idea, Quick question, Could you use a wind wall and say 5 of these fans connected to the wind wall and then have them link together? for example, if one motor is giving 10volts and I had 5 of them, then could I get 50 volts of is it just 10 volts no matter what?
Depends how you wire them.
If you wired 5 of them in series (each generator connected to each other directly) you would get 50v (assuming 10v on each generator) but the current would be equal to having 1 generator (around 3 mA).
If you wired 5 of them in parallel, (all generators sharing a common wire on each pole) you would get the 10v but would have 5x the current, so 10v at around 15 mA.
The power (as in wattage) would be the same either way.
@@Dorpz Thanks for your reply
Looks like the product being produced by a start up company Harmony Turbines demonstrated in a UA-cam video posted by Disruptive Investing - which thinks (!) its product can compete with conventional horizontal wind turbines
oh is that where that is coming from - harmony have been around for a while and use furling as far as I know - this doesn't furl
Link --2-- buy fan plz ?
thanks
If the design is based on an alternator what about taking a visit to the local scrap yard and grabbing an alternator?
or would that be way to heavy for the small turbine to push?
Please retest with an purely resistive load instead of LED , and try different resistances
Greta video again Rob.
What about using two units, counter-rotating so the coil rotates in one direction, whilst the magnets rotate in the other?
Could the same principle be applied to an Argos full size ceiling fan to generate electric and if so could you make one on your channel.
We need a small counter rotating wind turbine! The rotor and stator go in opposite directions.
I don't understand. I think the milliwatt calc was incorrect. The Propeller version put out 13 v * 4.5 mA = 58.5 mW of power. This new Vertical Windmill version puts out 12 v * 2.9 mA = 34.8 mW, which is much worse. I didn't include the ratio of the size of the prop to the size of the vertical windmill... were the expected results for the vertical windmill supposed to be the same? or were you actually expecting it to be less?
Yes the person doing the presenting seemingly lacks enginering skills and ability to make analytical conclusions from
observatilns andd laws of physics. . But see how many he got to participate
@@akehellstrom4912 LoL, One of the main reasons I subscribe to this channel is Mr. Murray-Smith's excellent variety of skills. I am certainly not going to see anything less because of simple miscalculation. We are all human. Also It's possible he was taking into account the theoretical maximum of the prop vs theoretical max for the vertical in his calculation... I wasn't sure.
Wouldn't it work even better if you blocked the wind from hitting half of it?
What would happen to the energy of the blocked wind?
I think the curved shaped that you would want to block, helps deviate the wind instead as to not have to block wind coming from any direction ever
Could put rubber / silicon flaps over holes.
Blows one way it shuts, blows the other way it opens, less drag.
Think i would start with more than 2 blades... The original fan blade had more. Then the idea of wind redirection would become applicable here.
Always use phi when designing new things.
So a wall of say 100x60miliwatt = 6 watts. Surely that would take a hell of a long time to make a difference? Or would the power being square of speed make a big difference? Ie in the real world as a garden wall we could get similar production to an extra solar panel or two??
Replace those magnets with neodymium magnets. But be prepared for what is called "cogging".
Car wheels are easy, bearings last long, im gonna try the mangus effect and water
Robert, can you possible post a link to where you purchased this cheap ceiling fan, I located one on banggood and it was £20 and not $4.00. Appreciate your suppliers link if possible, great video mate and love the inventiveness of your mind and thought proving creations. Keep them coming!
