Amazing and a huge thank you. Would it be possible to do a video devoted solely to the electronics behind a wind wall. What to use, how to connect and how so on?. Thanks!
Via your inspiration and older 3D files I built a five section unit similar in size to this one a few weeks ago. Also designed a similar axiial flux generator for it and It performs wonderfully! Thanks for your inspiration! I got great pleasure building it and seeing it working. :)
Would love to see a follow-up video on how to store the power in a Lipo battery and use it with capacitors or something to provide power to outside LED strips. Maybe combine it with solar. I'm guessing you need some way to not over charge the Lipo as well as not let it drop below a certain voltage that would damage the battery.
Two Points: 1) Redesign the rotor so that it has an axial flux generator on the top and bottom. 2) Redesign it so that you use a magneto-bearing on the top and bottom. While this may increase the cost a little bit, it'll improve efficiency and make it quieter.
He also showed an interesting idea in the past around single phase motors that use a capacitor to help with starting torque. That seems like an interesting addition when we talk about dump resistors on these circuits. Why not dump to a capacitor that can help reduce starting torque. Am I crazy?
@@thewatersavior I think you misunderstand. Here we have a vertical rotor, in his build in the video he has only one generator, Having two one at the top and bottom of the rotor would double output without limiting rotational freedom. However, placing a dual motor at the base of the rotor would have a torque limitation which would hinder spin up in low speed winds. Using a magneto-bearing setup would reduce overall resistance, improving efficiency. The minimal span for a dual generator setup as I described is about 0.3 meters or roughly 1 foot in height given the type of rotor used.
You bet I'm going to try it. First part is printing now - even if printing a complete set, with several blades, will take until the middle of next week 🤣
An axial flux generator fixed on the disk o the savonius! Now I happy! Can't wait to see a complete wall of these in action), and probably with two generators on the top and the bottom
Some great ideas and inspiration for everyone, the practical testing is great and gives a good idea of the potential design your definitely going to make a difference thanks for your time and efforts
So here's an idea. Instead of a column, you make it into an inverted cone shape. Put that inside a darwin structure that pushes the air down. Now you have one turbine that's collecting and blowing the wind down, then put a tesla turbine in the exhaust.
Most promising yet for domestic use I feel, thank you. I live in rural southern Scotland, quite remote, certainly no gas supply etc, and need to insulate my stone cottage well and find some background energy solutions. I suspect multiple approaches will be best, with energy storage best with a very large water reservoir beneath the floors.
Great work. You mention a valid point that the cheapness of parts/production/installation will enable large scale deployment. However, one unsolved problem limiting this scale up is the lack of recycling facilities for 3D printing filament. Since many of the popular filaments are not robust to environmental conditions and mechanical wear, there is the potential for huge quantities of plastic waste going to landfill when people start replacing parts. It's possible that recyclers will anticipate this, but it would still take time for them to respond at an industrial scale.
PETG is good for outside and the only mechanical wear is in the bearings which last for years and could be replaced. Maglev bearings idefinitely. PETG is also recyclable as long as its not in strings.
Hi Robert, I'm guessing a small gap between sections wouldn't affect it too much, if you put a rotor and stator on the end of each section, one on top and then added a bar to link the stators (and run wires) you should get 8x and make around 100v per strip.
I used a different tinker cad module that has sections. Between the blades and the section joiners, that thing took me a month to print a half turn. But it's nice and tall. Just got them replacement part from Elegoo. Going to have to try yours next. That one won't take as long and it's got the motor part😁 Curious to see if one long one and less generators or a bunch of short ones stacked and more generators would have the better outcome. Cheaper on wire and magnets if the tall one works better
Hi Robert, when I saw what you built in the beginning of the video my first thought (as a textile engineer) was, we can make that from textiles! A thin walled spiraled shape might not be optimal in the end but we can make this dirt cheap and with really large surface are. One would just need to clamp both ends in the twisted state so they don't unwind but that's not a big hurdle. We've got textile materials here at my company that last 10+ years outdoors without degrading in mechanical properties so I might give it a go with that. This thought only deepened when you were talking about production costs and methods. You need a pretty good plastic material to not degrade after a year or two outside and fall to pieces. The less of it, the better.
@@christopherd.winnan8701 it's a structure similar to a biaxial grid, but woven, made out of a special highly weather and UV resistent PES material. Threads are at max 0.15mm in thickness. It's sturdy, especially in cross machine direction, you can work with it like with every textile and it's extremely light for the strength it offers.
@@christopherd.winnan8701 in this case it is not used for that, but you could with a slightly different construction, I guess. It is not expensive when you compare it to what amount of material and what quality thereof you would need to achieve the same surface area and durability with other constructions like injection molded parts. But you'd do entirely different constructions when using both materials advantages to its best, I guess. I'm no expert in construction with plastics though.
I really like the Ugrinsky design, I'm currently printing these 2 Meters tall, applying the largest width I can get on a Elegoo 3 max. I plan on placing them on the roof line of the house, & thinking of placing differentials between them to transfer the torque across a horizonal shaft and turn a large RMS generator at the end.
I'm looking at doing the same thing. Where I live, the wind is either hitting the back of the house or the front, so the roof line is perfect. Have you made any progress on your project? I'd love to connect.
I have the same printer and same ambition, how did you go ? Grateful for any lessons learned; did you use another generator or scaled this one to bigger magnets and all ?
cheers mate - great suggestion - but you could just fill it it with resin or sealant if it bothers you - i personally wouldn't bother as it doesn't matter that much as all that is in the generator section is a coil of enamel coated copper wire and it already has a drain hole
You persist in challenging the minds of people towards discovery. A trait not as common as it should be. This project, Ugrinsky Wind Generator, as well as several others, are springboards of replication magnification. Inspiring the latent engineers to become active and be productive towards solutions. When I build my version of the Ugrinsky, the goal is to run a pond pump, charge a cell phone, run a laptop computer, and charge a 12v battery. To operate the devices, about 250 watts and an excess for charging the battery. What you have shown, franchise the design, building more than one. In this way, I can design a generator at a lower output amperage and cheaper material costs, then through multiplication produce the total output desired. Where 1kw is the goal, I can build several smaller wattage outputs until I achieve my 1kw goal. This is your Genius. The only question left for me, how good are my FreeCad skills.
What Ken said was not stupid, but i have a similar idea. If you build a vertical generator, with the generator in center of the rotorblades. This way you can build a tower of these, who are connecting to combine power output. So maybe you can build a 5meter tall rotating pole, that outputs a good stake of power. This way you can place them along harbours and between small cities along the open roads ect. where the wind is more abundant. Remember Robert, you teach us, output from inductionpower is made by the volts from the lenght of the copper wire, and the ampere from the thickness of the copperwire. So isnt it about time we see you test, optimizing a wind generator to turn a strong magnet in a very heavy copper wire so it produce a maximum of whats. Many people show they can make power, but it is not smart to make power in its own matter, then you can probably buy a better system, it is smart to optimize to a better system than we use today.
Maybe if you bank them via belt/chain/other you can get away with one motor and time them at the same time you can get them to inter lock, creating the same effect as the twin rotor HAWT you were playing with recently 🤔
Instead of a wall arrangement an alternative could be a pole. If there were a series of out rigger arms, say 5 or 6 rotors out at the lowest decreasing in amount with every ascending set, ending with a single rotor at the very top of the pole, in a sort of cone shaped/Christmas tree arrangement. Now, if they were made from green material, at even a short distance they would look like trees. The outrigger arms could hold netting to stop birds. Similarly, the same arrangement would fit perfectly onto roadside lamp posts.
I wonder, if fiberglass or carbon fiber and bamboo to build a huge one. Attaching it to a 36"-48" plyt disc to give it a axel, and make a magnetic rotor. Use a few strips about 6'-10' long, steam flattened and bent into a S shape. And maybe make a couple sections 3'-4' thick. A couple layers of fiberglass or carbon fiber with a few bamboo strips inside bracing the 'S' shape with 1.5" pvc bracing the axel area, a 3mm plate with steel tube welde to it . That allows the 1" steel shaft to be fitted to a couple bearings and a tortington bearing. In top of a 2" thick wall pipe, two bearibgs spaced a distance apart to stabilize the shaft, use a make magnet pads around tge 36-48" perimeter about palm size, about 5-6"across, ( i have large hands.) Use round or square magnets. About 3mm thick and 50mm across, poss using steel plate over it to attach to the plywood with screws, and caulk seal the plate over the magnet making the plate the magnet , with two rmagnet rings possibly using a sheet steel backer behind the magnet basically naking a group of horseshoe magnets around the rotor. With a large serpent coil epoxied to the edge of a plywood stater ring, fitting within 1mm of the rotor making a coil about the thickness of a 4/0 cable using 3/4, 20mm plywood cut the plywood to hold tge serpentine coil in the two rotor gap. Using a couple of braced 2"x3" 16ga steel tubes , with turnbuckles to adjust, and 2" x 1/4" flat bar. Bolted on using large washers with rebar 1/2" thick, welded to the ends od the 2x3 and to the 2" tube mounting everything, havibg 8 points of mounting the starter. About 24" apart in 4 locations. The turnbuckle adjust then 3/8" bolts in 1/2" holes in the plate , using washers or a more fitting washer plate, having two bolts per end, this will give about 3/16" travel for tge turnbuckles to make adjustment. The bars bracing that adjustment being there is only about 2-3mm total clearance using shims to set it up, mount everything and remove the shim stock, and rotate checking for clearance, if there is issues, use shims under the lower stater mount where clearance is lacking! Having a large turbine , this size, the ability to split the coil into about 4 coils to put it into all series , for low wind , to all parallel for high wind speeds, or series parallel, having about 10lbs of copper. In about 20 gauge enamel wire, zip tied and epoxied to the plywood stater to keep the wire close to the stater magnets as possible, with bolts attaching the lower stater about 15°-30° apart shimming small parts is possible. It should produce serious power, especially being light weight, the rotating mass, should be 20 lbs or so, the whole thing under 100+/-, a tower made from 1/4" x 2" angle. Roughly 40' (probably 35'-36' tall, with the tripod angles, Plus two sticks of sch 40 pipe, one fitting indide tfr other, the top smaller, being about 2" 10'minimum, with a 12" overlap , the larger fitting inside the tripod angle, making it 24" below the top, fir the bottom mount, so 36'+17', so just under 55' is about what i need, because of trees, it should produce nearly 2kw in a good breeze, vand a good bit more in a 50 mph wind, a 6'x 9' , to 8' x 12', or 10' diameter, and 12' tall, possibly larger turbine should grab alot of wind! Alot of TQ, and speed on the edge, generation. And more can be stacked, each 36" -48" tall section, veing mounted 30°, 60°, 90° or 120° to simulate a twist, a couple smaller molded over 55 gallon drums, and mounted over a 2" pipe 40'long, 20' being turbine stack. using 2-3 near each other, being nearly 60" acrross and each section 48" , maybe the better route, with a 24"-36" rotor/stater much simple to eork on, and 2-4 could possibly double tge output! Sorry to ramble!!
I was thinking of a upgrade. Basically a blade or a few that as it spins, the centrifugal force forces the liquid to the outside in which I was thinking would act as a stabilizer and will want to stay in motion. Just a thought
Instead of a wind wall I'd like to see a wind roof maybe something that incorporates a slate or tile replacement with generation capability so even if each tile produced a few Watts you could potentially become self sufficient
i have a idea don't know if it well work right for the wind wall but... using the The Magic Lever in 2003 to make lets say 5 different turbines shafts all turn the same way then use the lego Worm Gear in 2042 on the ends with one lego worm gear running linear to one generator so that we get 5 input in one output. i hope the lego worm gears wont bind up and that each turbine adds to the overall output and not fight with each other.
I'm working on something similar, although I'm using differential gears between the turbines, so they can spin independently at their own rate, and still transfer torque down the shaft.
Hi buddy I have a thought, as speed, velocity is a part of the equation could you print one wind turbine with a clockwise twist and a second with a counter clockwise then these could be stacked Left right left for example for every turn this should be twice the velocity at the opposing joints. Eg: 2 cars heading towards each other at 20 km per hour is equal to 1car going 40km per hour in a collision. It could also be done By printing a sprocket to turn a middle genset the opposite way, to get higher velocity
There's a variable table for the R, r, c and b and such
Месяц назад
Love all your videos. My question is what would happen at high wind speeds and gusts of more than 60 mph say. Referring to a setup like this in a wind wall.
Thank you very much for your demonstration. Fantastically ingenious. A super project for my life as a pensioner. One question: Is the ring that carries the mangnete capped with a metal ring? I had read that iron at least 1/3 the thickness of the height of the magnet almost doubles the power.
I'm thinking, 2 meter tall windwall, 9 rotors, generator on the middle one, and connect them with magnetic gears, you could make your windwall as long as you want, just repeat with as many as needed.
Having just watched another multi-mile long train loaded with wind turbine blades pass by my house, I am left wondering how long the American taxpayers will have to continue subsidizing the least efficient/reliable source of electricity yet devised. That is not a commentary on this great video, just an observation from the other side of the screen.
I absolutely love this design and while you have it as a typical VAWT as tested, do you think there would be much change to output if this one was turned on its side? I'm not wanting a horizontal wind turbine, but my thought was say, mounting one (or more) of these sideways on a boat or an RV roof - charging batteries while traveling seems like a good idea, right? Just a thought, really, but even after parking the RV, with this style mounted over the cab area, it could still spin in a breeze and produce some power day or night. I'd love to see any output differences in mounting this helix style wind turbine sideways if you ever get the chance or to satisfy your own curiosity.
I see you're quite fascinated by macaroni in energy generation :) A while ago it was a rotini generator (2047) Now - it's rotini turbine. Catching wind with pasta. P.S. I like your pet fly :)
I would like to see like full size aplication of that design, wich really can produce some power to fill up any battery, or light up your home, or heating your house. Otherwise your windpower things are only toys for children to play with.
So cool. Nice design. You could sell some kit of basic 3d printed wind turbine for people which dont have printers, because you have a army of printers!? lol
@@ThinkingandTinkering Yes I know ☺ it was only my thought, because you have so cool wind turbine designs and many people dont have 3d printers. You can make some pocket turbines or some pocket hand generators. But I also know that this can be a lot of work. Anyway, you make good work on Ugrinsky Wind Wall Module
Could you have magnets at other spots on the column with coils around them to gather more energy from the same amount of movement? I guess the support cage for the coils would slightly impede the wind intake, but still a net gain, probably? And adding a copy of the NSNS ring that's on the bottom to the top of the column would double your output for almost no efficiency loss, no?
Rob, I'm really intrigued by your wind wall project and thinking about creating something similar as a fence alternative. I live in an area with strong Atlantic winds and frequent storms, so safety is a big concern for me. Could you share any tips on implementing a safety shutdown mechanism or other ways to ensure the turbines won't pose a hazard during extreme weather? I want to avoid accidentally turning it into a 'plastic bomb' in high winds. Thanks for any advice you can offer!
I was wondering if you've seen the RidgeBlade models that utilize wind focus at the peak of a roof, and if you'd consider doing an experiment with a similar design.
HI Robert, I'm seriously interested in this type of wind generator. As a residential "eco" architect with an eye on energy generation at the point of use, I watch the catalogue of alternatives you present on your channel with great interest and Ive yet to see something with the potential this system has. As you say, not for its efficiency necessarily, but its geometry. Integration is the key component in designs for high density urban environments - that place everyone is migrating to! Beyond the end cost per kWh which is a question of mass manufacture, I was more concerned about noise and vibration issues. Lightweight? Low operating speeds?? Any thoughts on this would be of interest to me in any future episodes on this stuff. Cheers.., keep them coming!
Thank you 👍 I love this concept. I'm going to build one. I just need a 3d printer. I'm looking for one with a 300mm x 300mm build area. Any good brands/models people could recommend?
Some real life Issues: Operating Noise, UV-light, Humidity, Stormy weather. So how durable and tolerable (neighbours next to my balcony might 😡) is it gonna be outside the lab?
It would seem to me that with 10 rotors, the outputs would each be routed through a bridge rectifier and smoothed somewhat with a capacitor and then paralleled into a single battery solar/wind charger supply side. Does anyone have a better suggestion? I would love to hear some.
As the length of the spiral increases, how does that impact the speed of the vortex created? Any Schauberger experts here that can explain the vortical dynamics of the wind flow?
@@ThinkingandTinkering is that because the blade wouldn't rotate as fast with two generators because more force would be required to turn it? I'm new to this.
It would make it less efficient at low speed wind and more efficient at higher speeds. If mass produced you could have a system that could choose between having 1 and 2 generators, depending on the speed of the rotation, sort of like a regenerative breaking.
That's pretty decent out put I think . What would the output be if it was 3 times the diameter? 3 times ? Or would it still only spin as fast as the wind will spin and have same output ?
looked pretty fast like a gale wind lol, anyway if you get 5v it will be good enough, then use voltage tripler with diodes onto a capacitor to a battery system of 12.7 to 15 v.
@@ThinkingandTinkeringI was referring to the use of a laser tachometer, so, in the case of this video we could know the revolutions necessary to achieve those 12 volts. That would give us a reference of the difference that there may be between the generator powered by a blower and what it would be like in real life with the impulse of the wind. Still, as a demonstration, the videos are great! Greetings from Argentina!
GENERATOR - increase or decrease efficiency adding a second serpentine coil and set of magnets? also would there be an increase of flux across the coil by closing the loop with an “iron horseshoe” for each set of magnetics?

Hey Good evening great ideas. Where can i get a copy of the 3D print outs? Also do you have a step by step tutorial showing how to link this to generator and battery?. I need to create electricity for my greenhouse. Thanks in advance.
Hey Robert, amazing work as usual. I was wondering if its possible to do two turbines like this stacked vertically but with opposite rotation. In the middle of two vawts is a shared motor, the bottom vawt spins the stator/windings, while the upper vawt spins the magnets in the opposite direction. Splitting the motor into two halves like this could we theoretically double the power output?
@@PatrickGunderson I've seen automated systems and the cost savings would be amazing. I know it's hard work but it would significantly reduce costs. You could build a wind wall to power the 3D printer too.

But the issue is how to storage that energy for when it's needed or for when you don't have wind 🤔🤔
@ottonain , could we fasten a battery in the housing of each wind wall segment? That way, it's a complete set, totally modular.

This way you can build a tower of these, who are connecting to combine power output. So maybe you can build a 5meter tall rotating pole, that outputs a good stake of power. This way you can place them along harbours and between small cities along the open roads ect. where the wind is more abundant.
Remember Robert, you teach us, output from inductionpower is made by the volts from the lenght of the copper wire, and the ampere from the thickness of the copperwire. So isnt it about time we see you test, optimizing a wind generator to turn a strong magnet in a very heavy copper wire so it produce a maximum of whats. Many people show they can make power, but it is not smart to make power in its own matter, then you can probably buy a better system, it is smart to optimize to a better system than we use today.
Great I'll have a go at printing some for on top of my garden wall
That fly was ready for his closeup, lol!
I had a look at getting something produced by injection moulding in the UK. The cost of the mould was surprising, thousands of pounds for the mould
that is a good size to compare its efficiency against the tower fan blade designs
Maybe if you bank them via belt/chain/other you can get away with one motor and time them at the same time you can get them to inter lock, creating the same effect as the twin rotor HAWT you were playing with recently 🤔
Instead of a wall arrangement an alternative could be a pole. If there were a series of out rigger arms, say 5 or 6 rotors out at the lowest decreasing in amount with every ascending set, ending with a single rotor at the very top of the pole, in a sort of cone shaped/Christmas tree arrangement. Now, if they were made from green material, at even a short distance they would look like trees. The outrigger arms could hold netting to stop birds.
Similarly, the same arrangement would fit perfectly onto roadside lamp posts.
Very cool. Just sliced the models and am about to start printing one.
The better generator is the one you use with rectangle magnets and using the planetary gears. Might try the Ugrinsky with that generator.
Thank you Rob!
I wonder, if fiberglass or carbon fiber and bamboo to build a huge one. Attaching it to a 36"-48" plyt disc to give it a axel, and make a magnetic rotor. Use a few strips about 6'-10' long, steam flattened and bent into a S shape. And maybe make a couple sections 3'-4' thick. A couple layers of fiberglass or carbon fiber with a few bamboo strips inside bracing the 'S' shape with 1.5" pvc bracing the axel area, a 3mm plate with steel tube welde to it . That allows the 1" steel shaft to be fitted to a couple bearings and a tortington bearing. In top of a 2" thick wall pipe, two bearibgs spaced a distance apart to stabilize the shaft, use a make magnet pads around tge 36-48" perimeter about palm size, about 5-6"across,
( i have large hands.) Use round or square magnets. About 3mm thick and 50mm across, poss using steel plate over it to attach to the plywood with screws, and caulk seal the plate over the magnet making the plate the magnet , with two rmagnet rings possibly using a sheet steel backer behind the magnet basically naking a group of horseshoe magnets around the rotor. With a large serpent coil epoxied to the edge of a plywood stater ring, fitting within 1mm of the rotor making a coil about the thickness of a 4/0 cable using 3/4, 20mm plywood cut the plywood to hold tge serpentine coil in the two rotor gap. Using a couple of braced 2"x3" 16ga steel tubes , with turnbuckles to adjust, and 2" x 1/4" flat bar. Bolted on using large washers with rebar 1/2" thick, welded to the ends od the 2x3 and to the 2" tube mounting everything, havibg 8 points of mounting the starter. About 24" apart in 4 locations. The turnbuckle adjust then 3/8" bolts in 1/2" holes in the plate , using washers or a more fitting washer plate, having two bolts per end, this will give about 3/16" travel for tge turnbuckles to make adjustment. The bars bracing that adjustment being there is only about 2-3mm total clearance using shims to set it up, mount everything and remove the shim stock, and rotate checking for clearance, if there is issues, use shims under the lower stater mount where clearance is lacking! Having a large turbine , this size, the ability to split the coil into about 4 coils to put it into all series , for low wind , to all parallel for high wind speeds, or series parallel, having about 10lbs of copper. In about 20 gauge enamel wire, zip tied and epoxied to the plywood stater to keep the wire close to the stater magnets as possible, with bolts attaching the lower stater about 15°-30° apart shimming small parts is possible. It should produce serious power, especially being light weight, the rotating mass, should be 20 lbs or so, the whole thing under 100+/-, a tower made from 1/4" x 2" angle. Roughly 40' (probably 35'-36' tall, with the tripod angles, Plus two sticks of sch 40 pipe, one fitting indide tfr other, the top smaller, being about 2" 10'minimum, with a 12" overlap , the larger fitting inside the tripod angle, making it 24" below the top, fir the bottom mount, so 36'+17', so just under 55' is about what i need, because of trees, it should produce nearly 2kw in a good breeze, vand a good bit more in a 50 mph wind, a 6'x 9' , to 8' x 12', or 10' diameter, and 12' tall, possibly larger turbine should grab alot of wind! Alot of TQ, and speed on the edge, generation. And more can be stacked, each 36" -48" tall section, veing mounted 30°, 60°, 90° or 120° to simulate a twist, a couple smaller molded over 55 gallon drums, and mounted over a 2" pipe 40'long, 20' being turbine stack. using 2-3 near each other, being nearly 60" acrross and each section 48" , maybe the better route, with a 24"-36" rotor/stater much simple to eork on, and 2-4 could possibly double tge output! Sorry to ramble!!
I was thinking of a upgrade. Basically a blade or a few that as it spins, the centrifugal force forces the liquid to the outside in which I was thinking would act as a stabilizer and will want to stay in motion. Just a thought
So my 6ft fence replace with this around my garden, i can power the village!
Instead of a wind wall I'd like to see a wind roof maybe something that incorporates a slate or tile replacement with generation capability so even if each tile produced a few Watts you could potentially become self sufficient
i saw a nano-UFO flying around in the video.
i have a idea don't know if it well work right for the wind wall but... using the The Magic Lever in 2003 to make lets say 5 different turbines shafts all turn the same way then use the lego Worm Gear in 2042 on the ends with one lego worm gear running linear to one generator so that we get 5 input in one output. i hope the lego worm gears wont bind up and that each turbine adds to the overall output and not fight with each other.
I'm working on something similar, although I'm using differential gears between the turbines, so they can spin independently at their own rate, and still transfer torque down the shaft.
Hi buddy I have a thought, as speed, velocity is a part of the equation could you print one wind turbine with a clockwise twist and a second with a counter clockwise then these could be stacked Left right left for example for every turn this should be twice the velocity at the opposing joints. Eg: 2 cars heading towards each other at 20 km per hour is equal to 1car going 40km per hour in a collision. It could also be done By printing a sprocket to turn a middle genset the opposite way, to get higher velocity
@@marnielarocque9412 ok sounds good what came to my mind was to use the magic level but use two ratchet arm with different timings.
There's a variable table for the R, r, c and b and such
Love all your videos. My question is what would happen at high wind speeds and gusts of more than 60 mph say. Referring to a setup like this in a wind wall.
This wind wall would bei ideal to put it on a bautri-system
Is that a small jet fighter flying by the camera 🎥🤔
You're so close and yet so far away... you showed me yours, I'll show you mine soon!
Looks great. What will happen if we put the generator on both ends. Would it double the volume of energy produced?
Thank you very much for your demonstration. Fantastically ingenious. A super project for my life as a pensioner. One question: Is the ring that carries the mangnete capped with a metal ring? I had read that iron at least 1/3 the thickness of the height of the magnet almost doubles the power.
How about a wall with many different types?
I'm thinking, 2 meter tall windwall, 9 rotors, generator on the middle one, and connect them with magnetic gears, you could make your windwall as long as you want, just repeat with as many as needed.
Having just watched another multi-mile long train loaded with wind turbine blades pass by my house, I am left wondering how long the American taxpayers will have to continue subsidizing the least efficient/reliable source of electricity yet devised.
That is not a commentary on this great video, just an observation from the other side of the screen.
I absolutely love this design and while you have it as a typical VAWT as tested, do you think there would be much change to output if this one was turned on its side? I'm not wanting a horizontal wind turbine, but my thought was say, mounting one (or more) of these sideways on a boat or an RV roof - charging batteries while traveling seems like a good idea, right? Just a thought, really, but even after parking the RV, with this style mounted over the cab area, it could still spin in a breeze and produce some power day or night. I'd love to see any output differences in mounting this helix style wind turbine sideways if you ever get the chance or to satisfy your own curiosity.
I see you're quite fascinated by macaroni in energy generation :)
A while ago it was a rotini generator (2047) Now - it's rotini turbine. Catching wind with pasta.
P.S. I like your pet fly :)
I would like to see like full size aplication of that design, wich really can produce some power to fill up any battery, or light up your home, or heating your house. Otherwise your windpower things are only toys for children to play with.
So cool. Nice design. You could sell some kit of basic 3d printed wind turbine for people which dont have printers, because you have a army of printers!? lol
lol - i guess I do but I ave also done a lot of ways on how to build wind walls without 3d printers
@@ThinkingandTinkering Yes I know ☺ it was only my thought, because you have so cool wind turbine designs and many people dont have 3d printers. You can make some pocket turbines or some pocket hand generators. But I also know that this can be a lot of work. Anyway, you make good work on Ugrinsky Wind Wall Module
@@cayrexthere are services and people that can and will do it for you, if you paid. The designs are free, just find someone and send the design.
Thank you Sir :)
What if this was lying down at the roof top....
Could you have magnets at other spots on the column with coils around them to gather more energy from the same amount of movement?
I guess the support cage for the coils would slightly impede the wind intake, but still a net gain, probably?
And adding a copy of the NSNS ring that's on the bottom to the top of the column would double your output for almost no efficiency loss, no?
Bravo Robert
real nice
Rob, I'm really intrigued by your wind wall project and thinking about creating something similar as a fence alternative. I live in an area with strong Atlantic winds and frequent storms, so safety is a big concern for me.
Could you share any tips on implementing a safety shutdown mechanism or other ways to ensure the turbines won't pose a hazard during extreme weather? I want to avoid accidentally turning it into a 'plastic bomb' in high winds. Thanks for any advice you can offer!
Ha! Flies on you!
I was wondering if you've seen the RidgeBlade models that utilize wind focus at the peak of a roof, and if you'd consider doing an experiment with a similar design.
HI Robert, I'm seriously interested in this type of wind generator. As a residential "eco" architect with an eye on energy generation at the point of use, I watch the catalogue of alternatives you present on your channel with great interest and Ive yet to see something with the potential this system has. As you say, not for its efficiency necessarily, but its geometry. Integration is the key component in designs for high density urban environments - that place everyone is migrating to! Beyond the end cost per kWh which is a question of mass manufacture, I was more concerned about noise and vibration issues. Lightweight? Low operating speeds?? Any thoughts on this would be of interest to me in any future episodes on this stuff. Cheers.., keep them coming!
Turn electric railway train powered by the wheels on the boxcars. Your generator on the boxcars wheels
Thank you 👍 I love this concept. I'm going to build one. I just need a 3d printer. I'm looking for one with a 300mm x 300mm build area. Any good brands/models people could recommend?
I've started making one of these and wondered if anyone has done a remix of the Ugrinsky_Base.stl to mount it on the top?
Some real life Issues: Operating Noise, UV-light, Humidity, Stormy weather. So how durable and tolerable (neighbours next to my balcony might 😡) is it gonna be outside the lab?
It would seem to me that with 10 rotors, the outputs would each be routed through a bridge rectifier and smoothed somewhat with a capacitor and then paralleled into a single battery solar/wind charger supply side. Does anyone have a better suggestion? I would love to hear some.
Impressive and sexy model mate! 👏
As the length of the spiral increases, how does that impact the speed of the vortex created? Any Schauberger experts here that can explain the vortical dynamics of the wind flow?
i cant leave links to onshape documents, apparently
Hi Rob, great video. Could you put another axial flux generator on the top to double the output?
you could if you wanted mate but it wouldn't double output
@@ThinkingandTinkering is that because the blade wouldn't rotate as fast with two generators because more force would be required to turn it? I'm new to this.
more force required to turn it mate
It would make it less efficient at low speed wind and more efficient at higher speeds. If mass produced you could have a system that could choose between having 1 and 2 generators, depending on the speed of the rotation, sort of like a regenerative breaking.
Might as well put anothr set of magnets/coil at the top too.
Looks a bit like an old screw propeller on old ships.
Anyone got a part number for these thrust bearings?
its noisy it doesnt need to touch the magnets on the one end.
could you make a ventum turbine outer case with strengtheners angled to catch more wind flow, with a archimedes turbine inner
would a maglev bearing interfere with the electricity generation
no
That's pretty decent out put I think . What would the output be if it was 3 times the diameter? 3 times ? Or would it still only spin as fast as the wind will spin and have same output ?
Any idea if the Ugrinsky or the omni directional (ball) would produce more per square/cubic foot?
they will be about the same mate
Bird grinder😂
only if you cover it with razor blades lol
What about if you had essentially a chain with a larger motor at the end which could have a gear system
Very good videos! It would also be very useful to know how many revolutions the fans rotate to generate those voltages.
on occasion i test for that - but not every time or each video would be hours long and mostly repetition lol
looked pretty fast like a gale wind lol, anyway if you get 5v it will be good enough, then use voltage tripler with diodes onto a capacitor to a battery system of 12.7 to 15 v.
@@ThinkingandTinkeringI was referring to the use of a laser tachometer, so, in the case of this video we could know the revolutions necessary to achieve those 12 volts. That would give us a reference of the difference that there may be between the generator powered by a blower and what it would be like in real life with the impulse of the wind. Still, as a demonstration, the videos are great! Greetings from Argentina!
GENERATOR - increase or decrease efficiency adding a second serpentine coil and set of magnets?
also would there be an increase of flux across the coil by closing the loop with an “iron horseshoe” for each set of magnetics?
اسمع لا تحرك المغناطيس فقط حرك حديده فوق حقل مغناطيس يحيطه نحاس وسيولد كهرباء اكثر وبطريقه سهله
no mate that's not right - what you are talking about is flux switching - it's good but it also introduces cogging and a much higher start torque
@@ThinkingandTinkering لكن اداء محرك الدوران لا يتأثر اثناء وضع الأحمال على ملف الخرج وهذا الشيء الذي يبحث عنه الجميع سرعه الدوران لن تتغير عن استخراج الكهرباء من الملف
Could you add another set of magnets / motor on top and double the output. You made enough to charge a battery though
Hey Good evening great ideas. Where can i get a copy of the 3D print outs? Also do you have a step by step tutorial showing how to link this to generator and battery?. I need to create electricity for my greenhouse. Thanks in advance.
Why not add a generator to the top as well. Twice as much generating possibility.
Nice
cheers
I'm running low on magnets and filament 😢
Hey Robert, amazing work as usual. I was wondering if its possible to do two turbines like this stacked vertically but with opposite rotation. In the middle of two vawts is a shared motor, the bottom vawt spins the stator/windings, while the upper vawt spins the magnets in the opposite direction. Splitting the motor into two halves like this could we theoretically double the power output?
But which of the turbines you have researched so far would you build, if it were your only source of energy?
this one
What's the best material to print this one to survive outside ? PETG ? How many KG for 2m tall 5-6 side by side ? Thx for any rule of thumb
here's a quick question. do you know how much each 'segment' weighs or how many you can produce with 1kg of filament?
Would adding another layer of coil and magnets increase the power output by (near) 100% while only adding 2/3 the cost?
Hi Robert,
Very interesting as usual. What about linking all columns of the wall to drive a unique but larger generator? Does it make sense?
Have you looked at using PET bottles to make filament? You can produce a kilo for next to nothing.
yes i have and yes you can
Except for the time and effort that goes into producing a quality, regular filament ;)
@@PatrickGunderson I've seen automated systems and the cost savings would be amazing. I know it's hard work but it would significantly reduce costs.
You could build a wind wall to power the 3D printer too.
