How to make a Vertical Axis Wind Generator (Is it worth that???)

[@Handles_AreStupid]

A couple of notes for this design: 1) The half pipes need caps either side to stop the wind escaping the "sails" 2) You need to reduce the weight of the moving carriage quite a bit. Steel is heavy and will increase the friction of the system. 3) Place weights on the back of the half pipes (for inertia, making it more efficient in inconsistant weather) 4) Modify the geometry of the half pipes to add a flat angle of around 30-60 degrees to reduce drag. (facing outwards) 5) Try using materials with a lower friction co-efficient, like Teflon or oiled metal at the point of contact on the rotating carriage.

[@voldnr72]

What about modifying the blades to a design that involves two haves on a hinge with a light spring action to keep them open when hit by the wind,and allowing them to close, reducing drag when facing away from the wind. Thoughts?

[@mauricioberne5289]

I agree, putting in the caps will help, but also using some neodymium magnets to push the plate up to reduce the friction would also be of great help.

[@chrisw1462]

Even with optimal blades, vertical axis turbines usually turn slower than horizontal ones. They usually use a belt and pulley system to increase the generator speed. You could use a planetary gear set. It would be more compact, but probably noisier.

[@MohammadBashirShaikh]

त😂

[@noneyabusiness969]

use an odd number of blades, 3 or 5, and shorten the arms they are mounted on by 1/3 of the original length. that should increase rpm, and reduce drag force by keeping the blade faces asymmetrical to the blade backs....great video, earned a new sub👍!

[@parahjapheth7920]

One more today.

[@CyberviewU]

It seems the odd number of blades should not be directly opposite each other. Try 3 blades 120 degrees apart. Look at the 5 blade pattern on the hoverboard wheel at 0:54

[@akshayjain1525]

Yes This is actually the case. Please try a 5 blade version.

would the F P direct drive washing motors and others of the same design put out way more wattage if so how much wattage i have hear up to 1500 watts i know noneya business will give us facts!

[@noneyabusiness969]

@@ambersmith6517 I believe you are referring to DC treadmill motors? If so, then yes, the typical treadmill motor is "RATED" 2-3 hp. (1hp=746 watts) that is the consumption rating of the motor, at a given voltage, rpm, and load. when used as a generator, these motors are much more inefficient, so 700-900 watts would be about as much as you would see from the motor terminals. Bear in mind, you have to apply 1500-2200 watts of mechanical power into the motor to realize that 700-900 watts output, so your blades, and gearing into said motor has to be able to source this power from a given wind velocity the turbine is designed for. hence the "slippery slope" of physics strikes again....

[@kishalayhaldar5729]

Great attempt!!! However, I see a problem in bearing configuration. It’s not only the air drag that is slowing it down, but good amount of friction at bearings. The hoverboard motor bearings are radial bearings. They are meant for motor orientation on horizontal axle. But if you place the motor vertically, the bearings will not be able to arrest the vertical slip of the axle, and finally the stator will press on the rotor, causing enormous friction and rapid wear. You need to replace the radial bearings with thrust bearings so that the rotor (casing) is suspended over stator be those bearings, bringing down friction drastically.

[@slartsa]

I also tried building a vertical axis windmill but after I left my prototype out for a night for a test drive, I noticed the same problem with the bearings. After that I discarded the idea of vertical axis with hub motors.

[@roberthicks5454]

Another factor to consider is the size of the blades. With a horizontal axis, the bigger the blade the more higher speed stresses the axis. with a horizontal, the blades are always the same distance, no matter how big you make them. The blades you used looked to be about 2 feet long. Had you made them 5 foot, the speed would be the same, but the torque would be much greater and having a "transmission" such as using a pulley set with a 1 to 10 ratio would result in the generator turning much faster, thus generating a lot more power.

[@nexxterra]

I was just about to post this same thing...From experience as well...great thing about PI is that a pulley just a few sizes up is a lot larger, so 1X around it can turn a smaller pulley many times... I have mine turning 2 generator assemblies just fine.

[@movax20h]

Just a suggestion. You should use active rectification, do reduce the voltage drop, instead of using diodes / bridge rectifier. The diodes do perform poorly at low voltages, dropping substantial amount of voltages, and dissipating as heat. The better approach for low voltages is to use active rectifier with low R_DS(on) mosfets and active rectifier IC (available from various manufacturers for both 1 and 3 phase applications), which can bring down losses almost to zero. The active PFC rectifiers are a subject of the ongoing research, but there is a lot of very good solutions already available. Granted, non of these advanced PFC methods are really needed here, as this is a low power project, and losses are not that important, but for big applications, the PFC is important, to reduce losses, and also smooth out the current (so there are no vibrations in the generator due to changing "load") Otherwise good attempt at the build! You need to change the shape of blades to make it really work.

[@ANURAAGNIGAM]

My points are (1) Reduce the No of blades to 5 only (2) Do not mount the blades from the center of curve , mount it nearer to the edge (3) need to edge the side profile of blades for better aerodynamics (4) Extended more arm length & use PVC pipe instead of M.S sq. pipe Thanks & best Luck !

[@oldhardrock2542]

I have been thinking of this type generator a lot lately. In about 1960 my Dad took me out to a remote natural gas compressor station. In those days, they were staffed 24/7 and the staff lived right at the station with their families. This station is in a very windy area. In spare time, the crew used an axle from a junk truck . One end they welded a playground merry go round and the power from half oil barrels similar to the half pvc pipes used in this video. When the wind blew strong, the thing woould go around way faster than we could stay on it. They had incorporated a clutch to stop or slow the merry go round and had another way to disengage the arms when the wind got to blowing too hard. Say, over 50 knots...

[@girthquake1413]

Dave below, mentioned that this turbine style is most suited for consistent power generation versus min-max like the classic style and lots have given ways of improving them; building the blades from a different material would be my first choice. One of the big advantages to this one is noise- or lack thereof. I've been around commercial 3-blade turbines during tornado weather and they HOWL.

[@cvabds]

You should make a gearbox, the new design provides a constant rotation but at a slow speed, so put a flywheel to help with momentum and a gearbox that converts the high torque low spin into high speed for the motor

[@tazholio]

yeah this is a good comment. VAWT's are high torque low rpm compared to HAWT's

[@fish9468]

Flywheel?! Are u kidding? Never use a flywheel for wind power. The gearbox makes sense but won’t be efficient. It’s better to reduce the blade distance from the shaft to increase rpm.

[@oopswrongplanet7309]

Nice, practical project. Very well executed. I really like that you drill and tap, and don’t rely on flimsy hot glue and CA to “tack” stuff together. This is a well engineered project that would have a reasonable chance of some longevity against the environment. Keep up the great projects!

[@fowadiqbal]

This is actually a turbine using drag force to rotate. Lot of scientists saying yeah kar lo woh karo but in reality drag turbine are not efficient as the turbine which uses life force. The reason is because it also create drag force in opposite direction. The swept area of turbine is good but its also letting lot of air passing by without converting into energy. If you put smaller size wing inside of bigger wings they will help to convert more wind into power and will also help to start on low wind speed. Numbers of wings should be odd as industry standard but should not be less then 5 for drag turbine. You also should also test with different wing configuration. Numbers, length and width of wings. width of wings can be increased .I always recommend my students to Study little science before making any product. Overall good work

[@davidphelps7763]

I would like to see you reconfigure your experiment by changing blades to airfoils

[@coyp2354]

[@tonyaltobello6885]

yes this will make it sooo much more efficient

[@HARI25able]

The resistance in vertical model is a blessing in disguise.. Yes it'll produce less energy. But it prevents the turbine from spinning too fast leading the motor exploding, Which is a drawback of horizontal model. You can integrate a solar panels on top of vertical model or place 2,3,4 veritcal models on roof top which can survive stronger winds.

[@RajvirSingh-ew8bd]

The length of the square tubes connecting the blades to the motor is long, this cause the RPM to be less as compared to if the the length would have been shorter.

[@Alrukitaf]

However, a longer length gives higher torque, so it should be possible to get higher power outputs with the vertical axis design. The problem also is the weight of the square tubing. But this video demonstrates quite clearly the comparison between horizontal and vertical axis designs.

I think the issue is with Ur light weight blades vs. Heavy metal centre. Also pvc is flexible and u wasted a lot of wind power right there. If I were u then will try to make blades with heavier material to compensate the central heavy weight or a bit heavier than centre metal weight attached with hovar board motor. Also increase the size (length and width) of Ur blades will make big difference. Anyways excellent video. I have seen many of Ur videos. Good work there u have done.

[@engleblerthumferlumpadinck6536]

Would a sailboat go faster with a sail made of metal?? What about a helicopter with a rotor made of lead? Of course not. Heavier blades on the turbine increases it's inertia. Meaning it will be slower to spool up to speed, and become inefficient due to the fact that inconsistent gusts of wind would not be enough to turn the turbine to produce any significant power. Therefore, the blades need to be light as possible. Aerodynamics and efficiency of the blades is key.

[@bingosunnoon9341]

That looks remarkably like the vertical wind turbine we built in college after the first oil shortage in 1973. It was a lot of fun and every university was doing it. I'm glad they're still around.

[@TrentTationnaiseXization]

Decrease the length of the arms holding the blades. The shorter you make them the faster it should spin. On the other hand make them longer for more torque.

Great video. An increase in wing design will change the problem. Use lift to move the wing, not just air pushing the wing.

[@frikkiepretorius432]

Correct. The 'blades' should be wings that will create lift when flying into the wind. Centre of lift vector points away from axis and is offset to wing point of fixture

[@daveamies5031]

From my understanding of VAWG they spin nearly the same speed regardless of wind speed, their benefit is being able to generate constant power in variable wind conditions and being able to continue running when wind speeds are too high for HAWG. Perhaps you just need to redesign it to make the motor spin faster, either shortening the arms as suggested by @Trent Pettyjohn or with some gearing?

[@tihomirrasperic]

in fact they they need a gearbox with 1:4 ratio in start, so for 1rpm of blade, you will got 4 rpm or generator or even bigger ration (need test)

[@alanmiller8390]

If you use a vertical Savonius turbine, I found by design that using two halves cut from a 200L drum and mount them onto the vertical shaft. Then make a large wing (side view) big enough to cover one half of the drums. Make the leading edge and dihedral large enough to allow the wind to cause a vacuum on the lift side. Only one half of the drum will be in the air stream on the high speed side. Use the vacuum from the "lift" to help the half of the drum inside the wing shape to spin towards the leading edge. Make a tail long enough to keep the leading edge into the wind. Mount the "wing" onto the vertical shaft. You can make the tail able to make the leading edge rotate away from the wind stream. Using the vacuum from the lift side should give you a 10% increase in power. Remember who gave you this and quote my name. Where I live, the Spring and Summer South Westerlies average 20 knots from approx. 1330 to 2000.

[@lucgauthier3201]

Your vertical windmill as no flaw, your design is almost excellent your just need to change the pitch of your blade and maybe change your blade for bigger one. Faster you want your windmill run , bigger the pitch of your blade as to be ( with less restrictions to the wind ), in that way you will have less torque but more RPM. Your design is made for high torque , no high RPM. KEEP GOING MY FRIEND, YOU ARE ON THE GOOD WAY.

[@paulschimel3572]

Neat project! I have a couple suggestions. One. The flat brackets may be less resistant on the curved side of the blade. The other I always wanted to try. Have a sheild that moves with a vane to keep wind off the back sides of the blade. I am curious how much it would effect it. You could go a step further and use it to direct more wind to the working side. 🤔

[@g09560]

What if it's just to much hard wear? Could a step up transformer be added 🤔 maybe some type of converter?

[@richardt.6793]

The vertical axis (VA) wind turbine was being developed by Dr Peter Musgrave at the University of Reading, UK. This was during the 1970's. His design also had a feathering feature to stop the blades spinning too fast in a high wind. The main advantage to the VA turbine is the heavy generator can be at ground level, thus reducing a need for a really strong tower to support it at the top.

[@abualis1178]

What a load of nonesense, wind turbine were used by the ancient Egyptians to grind grains and possible well before their time stop associating UK history

[@dcawkwell]

Great video. Unfortunately you used blades that will be limited to the speed of the wind. Ideally use aerofoil type blades this will allow the turbine to turn at a rate faster than the wind speed and therefore generator more power. It could also be that the generator is a little heavy for the current blade design to turn.

[@Reman1975]

IIRC, commercial vertical axis wind turbines use blades that work a bit like aerofoils to increase the percentage of the rotation that's capturing energy. At the minute, these "Cupped" blades are only really catching the full energy of the wind for at most a 1/3rd of the rotation. The other 2/3rds of the rotation the blades are either in turbulent air from other blades moving in front of them, or creating drag due to moving directly against airflow. An interesting experiment (assuming you still have this turbine (I just noticed this video was uploaded 3 years ago).), would be to redesign each blade mount slightly to allow them to be tilted so you could see how that affected the output. It's hard to describe what I mean by "Tilted", but at the minute the front straight edges of the cupped blades are both in line with the arms. I'm on about rotating the blades so they're still vertical, but the outer straight edge is further forward than the inner straight edge, or to put it another way, having the mounting holes in the blades moved sideways so they have more of their surface on the outboard side of the mount than the inboard side (God I with KZbin allowed us to post doodles, or even links to doodles, in the comments. It would make explaining this sort of thing so much easier. 😕 ). If the blade mounts angle was adjustable it would allow the setup to be tweaked to see if changing how the blades present to the wind could effect power output.

Hey! I have some suggestions - 1. Using a motor with lower rated rpm might work. 2. Using step up transformer might help. 3. Longer blades might make it more powerful. 4. Placing blades nearer to the center will increase angular velocity of the wind and thus, the rpm too. By the way, I still think the vertical axis system is better due to less moving parts.

[@vivekpant2237]

I just made some calculations regarding angular velocity of wind and now I believe that one cannot get high rpm in vertical axis turbines, but I think the torque must be high. You should either use different alternator for this project or use a gearbox.

[@ruiverissimo2864]

I don't know if someone already pointed this, but I'll do it anyway. It strikes me the difference between your "good" generator (horizontal axle) and the new one: surface area! A little bit of mechanics will tell you that the power you can get from a wind turbine is always proportional to it's area, and you can easily check your vertical is about a tenth of the horizontal one. Remember your vertical can only count on ONE blade at a time, whereas your horizontal as the THREE blades allways facing wind. Bottom line: I believe it's a good project, but blades have to be bigger. Also, as a side note, I believe you should mind the balance: maybe the rotor is not balanced, and there will be some friction drag ruinning the efficiency. Good luck. Thank you for the movie.

I've always thought of putting a wind shield on the backside to reduce drag and put a tail on it so it always points the right way. What do you think? Can you give it a try since you're 70 percent there? Good work. Thumbs up.

[@larrywhalen127]

CHM, a tail will only be beneficial on a system similar to a windmill in order to orient the vanes/rotors/propellers into the prevailing wind - this system is vertically oriented so does not rely on the winds direction, only the fact that it will spin regardless of which direction the wind comes from. Also, what are you referring to when you said "windshield" since anything else will cause undue parasitic drag on the system.

@@larrywhalen127 Larry, I just left a full post about the same concept 5 minutes ago. A "windshield" could be a half cylinder lowered over the whole blade assembly. It seems that even cupped the back sides of the blades are loosing momentum in the system by fighting against the same wind which is propelling them 180 degrees around the device. If the wind could be shielded on the back or return side, then this continued drag on the system would be eliminated. Please see my full post for more details on such a setup.

Although single surface airfoils are a step up from a 'flat plate' similar to the 10 cent balsa gliders we had as kids, they still create a good deal of parasitic drag, which is the nature of the beast. The best way to eliminate adverse drag in this situation would be to cut a thin, flat (1/8") piece of the same material (PVC ?) and glue it to the concave side of the blade, and then sealing the opening at the tip, which will result in additional rpm and therefore more energy produced.

Repurpose your vertical axis wind generator into a horizontal tip the blades like the other fan and your efficiency should come up as it is in the other wind generator but you'll have more surface space.

[@sub-zero-x]

Hello, nice project, thanks for sharing. To get a much better result with the current design, you just need to split the windings and reconnect them in series. 6:32 every coil of your wheel consists of five parallel wires per winding. Just split and connect them in series. End of the first wire to the start of the second. And so on for every winding. This will multiple (x5) the output voltage and significantly increase output power at low RPMs. Next two improvements are optional, as they need more extensive revision. - It seems that it makes no sense to make more than three blades, more blades also reduces speed. - And also a significant increase in productivity will be the creation of a full-fledged Darrieus rotor, but for this it is necessary to replace the halves of the pipes with a NACA0018 profile wing.

Mount the vertical blades in such a manner that each blade can pivot freely about a vertical axis. Provide a stop in each direction to prevent momentum from causing them to spin too far. This design eliminates the drag as all blade cups will remain oriented to catch the wind as the turbine spins.

[@StefanReich]

Great, but this "KZbin music"...

[@AR-rf9hc]

I have two points in mind to reduce drag on this turbine. 1. Reduce no. Of blades to 3. 2. Reduce to width and length of the blades

The problem with VATs is that gravity produces friction on a small isolated spot, which is also an advantage if you can use magnets to levitate the axial bearings

[@bingosunnoon9341]

The problem? There is more than one.

[@johnny5stickswilliams696]

Dispense with the stupid electronic music, we are only interested in the engineering not stupid music

[@eastrockaway3358]

cleanliness, precision and attention to detail. Beautiful job

[@jerrybritton5724]

Great Project. Can I ask you to due an experiment? The experiment is miniaturize it in America we use dryers to dry our cloths. Make that turbine small enough to fit in the exhaust hose and harvest that energy. We also use ac units to cool our homes. A large fan outside is used to blow air across the cooling tunes. Build a turbine over the cooler to harvest that energy.

Hello. I have a POTENTIAL SOLUTION to the problem of the back side of the blades having to fight against the wind speed. I have thought about this for years regarding a below mentioned design, but never built a model to work through it. Possibly you guys could try it. It seems that shielding the back side of the blades might help out much. This could be done by lowering a large partial cylinder over the entire blade assembly with half of the cylinder cut away. The cut away portion of the cylinder would be situated on the side of the blade assembly that is catching wind, while the back side of the blades would travel through an area shielded from the wind and negating this drag force that is limiting the power output with your current design. The large cylinder would of course have to be mounted on a carousel to enable its rotation to adjust for wind direction. This could be done passively with a wind vane above the whole device connected to the cylinder accordingly. There would have to be ample clearance between the blades and the cylinder to ensure their free flow through the shielded side without any compressive force developing as the blades enter this zone, as the compressive force could lead to vibrational issues, this aside from continued drag on the blades. I have thought about this concept in the form of a series of horizontally mounted blade assemblies on the top ridges of residential roofs with only the "air catching" sides of the blades exposed while the return path of the blades is shielded in a housing. Although these are unidirectional, there are plenty of regions with a predominant wind direction for large portions of the year that could utilize such stationary power generating devices.

[@johnburns2895]

Remove the drag by only exposing the power edges to the wind. Bury the turbine into a wing. And support the rotator with permanent magnets. A slight lip at the trailing end of wing self aligns the leading edge of wing into the wind

[@prateekpathak1652]

Well this generator is useful for constant voltage.. and constant power supply. It will rotate with constant speed even in low wind condition. Well nice project. Keep it up.

[@muhammadmujahid2789]

If u want more rpm to generate more electric, 1. Decrease wait of iron.. 2. Use bearing on both sides, to increase rpm & speed. 3. Install the unit 10 feet in height.

[@joelbustamante9906]

2. Use bearing on both sides, to increase rpm & speed. You mean to and bottom?

[@robertwoodliff2536]

Windage ( the problem of the return stroke ) was the same problem ( ok ok ignore the water ) , with paddle steamers ( and boat rowing ) , there was a steamer ( Reliance ) which furled the blade on the return stroke to help reduce losses .

[@nicolekroplewski4152]

The main problem of your blade are to some extent simple, I explain ...when on one side the wind push one of your , (let just call them wiglet ) On the other the wind slow the motion of the wiglet. To Resolve this issue, you will need the wiglet to fold in , to have less friction with the wind then unfold when taking in the power of the wind. Nicole.K

[@jonathanrose456]

You could try turning it on to a horizontal axis, cover the bottom half & putting an extra piece of pipe alongside on each of the propellers

[@josephnevin]

Dude!.. you're awesome. India needs more out of the box thinkers like you.

[@anasmusameh7206]

If you turn the turbines 45 degrees around their vertical position and then tilt them 45 degrees forward toward the center, you will get an amazing result.

[@sjandrestrydom1104]

Adjust your blades by 10 degrees and add a slight outward twst to the blade tips will increase performance

[@wimam1977]

If u fixed a bigger engine it will be more efficient as smaller engines require higher spinning rate to generate sufficient power while bigger engine with the same spinning speed can generate a higher power but u need to work on the air fens as they have to be big enough in length and width in order to be able to spin the engine....just a thought which deserves some attention

[@vladimirnekic3241]

On the vertical unit, instead of a vertical/straight up and down PVC that is cut in half... create a V pattern by cutting them in half so they look like a " < ". The wind will still grab and push but the arrow dynamics will allow for a greater spin speed. Second, look at better bearings...possibly some experimenting in magnetic zero friction.

[@c.n.h4841]

A smaller arm setup would greatly increase the possibility of higher RPMs due to the more mass you have to move. Along try a 22.5 inward Direction towards the motor so it creates more of a cyclone and or tornado effect it may help

[@pranabgill1310]

Hi...really appreciate the effort and knowledge,just a small suggestion. Reduce the length of the arms.This will increase the rpm. YES, this will require more torque(higher wind speed) .I am sure you cN strike a fine balance between the two. Again,I love the concept

[@oBseSsIoNPC]

I always feel like that if there was a better design than the one the big guys use, then they would switch as well. This is about being efficient, as cheap, easy and as fast as possible. Yet they always use the 3blade design around the globe. The whole "overspeed control" that people see in the simple design demonstrates the inefficiency. If there is a braking force, then that means wasted potential. Propellers are the way to go with wind turbines. Fantastic video though.

[@steve.wonder817]

You should make one with a spiral design similar to DNA, not stacking them at the same elevation like you doing this video, but staggering them with their height, creating a spiral affect or you could make the blades foldable and retractable into the wind and then pop open for the win so they won’t be equalizing themselves with push and pull from one side to the other

[@wiesawcetnarowski8722]

Hello. The coils of this motor are wound with a wire connected in parallel 5x0.5. To increase the voltage, cut them open and connect them in series. The tension will be higher. (5x)

[@rottyhome]

Change the blades. I agree by having an odd number. Try using making a more elongated scope like a fish hook shape. You could also put a motor on the top and bottom with a cage around it so with much bigger fish hook shaped scopes along with two dynamos should pull in much more. You have to make yours scopes bigger.

[@jlsboi]

Fan turbines have the benefit of gravity to assist in rotating the blades whereas vertical ones do not and strictly rely on horizontal forces. That’s why they’re more efficient. Forces from 2 axis vice 1

[@dimik3855]

Shorter arms, less weight, and if you want 500rpms, make sure it's balanced. Excellent effort!

[@paulmoffett8707]

To reduce drag on the trailing blades provide a shelter region, use a weather vien setup to keep in optimal position.

[@pkillor]

Magnificent project, A suggestion, could you make a workbench, ? it is much more comfortable to work standing up than lying on the floor, I think it is a custom of your country that I don't quite understand, knowing that you have the mechanical means to do it.

[@TinyHouseHomestead]

You needed to use a alternator with a belt to increase the RPM, then it would be more efficient! 😁👍✌

[@devtasingh]

It will need RPM multiplier. This design has mor torque but less rmp, With a bicycle wheel and a piñon (little gear) yo can multiply the speed in RPM. Another thing (if your structure supports that) is to increase the blades surface to use much more, you can double or triple the torque and the you can convert that to a much greater RPM with a several pulleys or chains mounted in bicycle wheels in series. Thank your for sharing the video!

[@darkmaster9607]

Also, if you angle the blades 10 degrees forward (or back) you can catch up-drafts and down drafts...

[@pierremarguerite2656]

I share one thing with u with my experience the number of blade should be 5 or 7 because at certain moment the wind tend to balance the set of blades reducing the rpm and you could make the arm supporting the blades adjustable from the centre for a better vortex and try several adjustment . Kind Regards .

[@FedericoLucchi]

Moving the blades closer to the shaft would decrease torque but increase rotational speed. Great project anyway, I might give it a try
