Hi, I'm in Australia. We have been using 'wind generators' for over 100 yrs. We have tried a lot of designs to improve the old "Dunlite Windgenerator". What your doing is bloody awesome, keep it going.
You are exactly on track with what have thought for a long time. Golden ratio capture and conversion of the wind for most efficient processing of it and a way for excess pressure to mediate or pass through so as not to stress the the prop. Putting these in an array, minimize with magnetic bearing any resistance. Make them cheap, small, modular and easy to replace. Cost effective wind conversion anywhere to get the ROI right up asap.
I also saw these as a match made in heaven 😊. Also because it would allow the use of the ball bearing tip to get low friction. One thing I have found which is very important, is that these Neobidium magnets do not like being outside. If the surface coating is even very lightly scratched, the magnet just turns to rust dust.
I just love your videos Robert Murray Smith. So enthusiastic, joyful as well as a brilliant and very practical Engineer. I wish there was someone selling these as kits they are an amazing piece of kit. 🙏
Dear Robert, I would love to see a huge 3D printed version, even if it needed to be printed in parts, put together and then get an amperage reading to see what energy the surface area achieved. Thank you for your interesting and educational time here . Rating: ⭐️ ⭐️ ⭐️ ⭐️ ⭐️
That's impressive. I would love to see this installed totally complete waterproof and everything have it working for at least six months and see what the readings are on a daily basis. Love to build one of these.
brilliant video! I just watched a video for the new Liam F1 wind turbine and this was suggested - great to see how these experiments have a potential commercial application!
That's a really nice build - maybe my favorite of your designs yet! I'm excited to see how it performs. I live in the southeastern US and my heat pump runs probably 9 hours a day on average at this time of year. I think I can make use of that exhaust air from the condenser fan, providing it's enough to collect and use in the shop.
It's worthwhile considering that if you added this to the air pump exhaust flow, you might be effectively making the air thicker. I'm not sure how much excess there is in the fan, but it's possible you could cause the fan to need to work harder, or limit the heat input/output. Ultimately, conservation of energy, and I don't know how that would impact that kind of setup, it might be negligible though, in which case that could be an inventive way to net increase efficiency. Not sure how you'd test it. You'd need an isolated system with effective ambient temperature control and then attempt to see what kind of temp differential you could create for some unit input of power with the power harvested subtracted off.
@@azena. Excellent point for sure. This is a typical fan though that blows vertical into the atmosphere with no restriction, not like in a pipe or constricted area. So if I covered it up with like 16 of them it might have an impact, but likely not noticeable with a couple. Good thinking, thank you.
@@skampp Quite possibly, it's difficult to say without doing tests to verify. The impact of a couple may very well be negligible, but then again who knows! I guess it also depends on the kind of environment the outdoor units are tested in. After all, they have to deal with wind from multiple directions, so actually, maybe there really is nothing to worry about. I can feel the variable list and unanswered questions growing 😂
Beauty!! My phone requires 20 watt hours max to charge. If we could measure a 2 watt hour output, given your approx 30V output, we would only need about 66 milliamps to have a wonderful camp side charger!! AND it's wonderful to watch it spin!
The improved efficiency spiral wind turbine was already Patented in US by Japanese man in Texas, a long time ago. Large scale models also built. It's called Tornado turbine. Also, the late Mr. Baumgartner had built a lifting device platform utilizing the ETHER , by swirling of turbine air with high rpm motor, very low power , and lifting very heavy weights. (Extracting energy power from the ETHER through angle of NATURE'S spiral). He used computer program to get exacting design . Two-page article with photos was in an old Alternate Energy newspaper.
I was thinking along similar lines. The space between my house and my neighbour's is like a wind tunnel. A number of them mounted on the side wall would probably be very effective, would be easiet to maintain than if they were on the roof, and would be fairly unobtrusive.
Now THIS is a good project for me to build. I could use something like that for my greenhouse which could use some light. I could think about a couple of these in a row. I absolute love the joy and enthusiasm you put out!!! 40V!!!! That joyful laughter is amazing and the thingy is brilliant. Just downloaded the files from thingiverse. Should be printable on a Ender3 (because of the size). Two years ago I run into hydroponics to vertically grow vegetables in. The first test was really good so in the following year I built 4 of it. Hmmm, thinking about your project combined to make the small pumps running is another good idea I could think about. That would mean I could run those pumps with a wind turbine recharging 12V battery. Hmmmm.... yesssss! Thank you!!
Do You know why ship propellers aren't shaped like an Archimedes Screw? Because it was found that if you cut the screw off at a point where the top of one blade starts to cover the bottom of the other, it's more efficient. It's a simple optimization that's been known for over a hundred years now. I bet You'd find the same if You were to cut the height of the screw in half and just keep the wide base.
First of all: I love your videos! I love the topic and you explain it so simply and well! Can you explain a Halbach array and possibly test it? I know it's complex and you say that simplicity is often the key😄
Robert, ☝️☝️✍♥️ maybe a series of forward facing funnel shaped shroud , then cylinder cover, and then tail components to first collect wind like an open funnel similar to what a dog wears after surgery, and add an interior rough surface or dimpled surfaced cylindrical wind energy concentrating housing shroud placed 360 degrees closely around the auger's length as a wind energy cylindrical concentrating surround to direct the wind energy to pass over the auger's fins in a parallel fashion and at a higher wind speed with the third component being that of a well set back trailing fin to turn the auger steady into the wind designed like the 1900's U.S. farmers type simple fined water pump wind prop with flat sheet tail. Think of a tail shaped like a boomerang so that the top and bottom surfaces of the trailing tail are out of the auger's vortice exhaust wind turbulence. Please keep up the inventing. I hope that You and Luke have a Happy Day !
It really is a beautiful mechanism. Aestheticly pleasing as a functional piece of art. I wonder how that impeller would work in reverse as a propellor? The impeller reminds me of the suction driver in an old Kirby vacuum cleaner.
Nice Construction. It spins well. It makes voltage. Put a little load on it and see what happens. Maybe you could get enough power to charge a phone. It needs to be much bigger to serve a useful purpose. I think a large one could be hooked to a hot water heater to get a little free hot water if you have enough wind.
Very interesting. After building a number of da Vinci Inventions, I think building some of your inspirations is a great inspirational jumping off points.
Robert, I enjoy your videos and I would love to see you build my idea. I envision a two foot metal rod with a large archimedes turbine on one end and a generator winding on the other end. There are magnets that create a mag lift to the rod and in the center of the rod there is a flywheel. The flywheel has holes drilled at a 75 degree angle that house magnets that generate a magnetic push once the wind starts the turbine spinning. Mounting it on a platform, would allow for adjustment and maximum wind capture. With the hand powered spin of the flywheel the turbine and magnets would increase the speed with very little resistance.
Hi Rob, I noticed that the Archimedes spiral is very similar to a sharks egg capsule. Nature has usually evolved answers up to the Murray-Smith level. André
You have some really great designs and I plan to print some to experiment with. I would like to see it hooked up to a load and tested for amperage though.
So here’s the big question … Which of your wind generator designs over the last few months is the most efficient to produce the most power? Would love to see.
@@andrewsmithmilan1780 The vertical axis "impeller" (can't remember the name) is more "robust" and omni-directional, but has a 7% efficiency rating. It's used for phone charging at remote bus stops in Europe. A unit large enough to run your house would be THE SIZE of your house.
Is the spacer supposed to be loose in the coil former? I noticed in the video that there is a gray space? in the blue coil former. What keeps the coil from floppying around?
Bilbo Baggings / Dr Who mashup. I love your videos. I've just subscribed as the videos are fun, entertaining and teach so much. You are an awesome teacher. You passion is infectious. Keep up the amazing work.
Theres not enough surface area for solar cells to pick up sun properly plus if its a moving object the cells dont have enough time to pick up light and generate the energy properly. Good idea though.
Because the intensity of the wind varies a lot, the wind turbine will vary to. The graphics of wind strength for a specific área will determine what kind of turbine works better.
IMHO it could a good video three wind turbine moving generators of exact same type in the exact same place at the exact same time and compare the three later in the lab.
I would be interested on the efficiency of the different designs. If you have much wind, all would work and generate enough energy for privat cases, but mostly are low wind conditions with less energy inside. So its important to use the theoretical possible energy with low wind efficient. Sure it is not Trivial, but maybe you can test equal scales of your designs on a big ventilator with the same generator and measure the power output? Very nice work you do!
Can i ask , why are there not manufacturing companies working with you to turn some of your interpretations and quite genius ways of proving a concept in to working and manufacturing turbines . I am sure that there would be a market for such devices . Keep up the good work .
i think you will have a very popular store, like home depot, that every educated client who understands well your u tube would not hesistate to order parts to build this wind turbine for domestic or field usage because its simple & workable to the ordinary people...........
I think a bit of the wobble/unbalance is due to the spiral not being evenly distributed in weight. A way to counteract this without messing with balance weights would be to make it a double (or more) spiral. Fun video though :)
I do love your videos and the frequency of your experiments for I would think there's a lot of time spent off camera to get usable footage, thank you for sharing,This is very cool. So will you get the same impressive results as you scale upwards , will the size and mass of a larger turbine create more friction on bearings stopping to the turbine from turning.
That turns pretty good for the size of it. Can you attach a load and retest? Also, is there a max speed or some way to brake at a limit so it doesn't fly apart?
A thing of beauty! Reminds me of a squid! What with the waistcoat and watch you are in danger of going full Dr. Who. It's a slippery slope. Take it from me! Perfect comic timing, tell the rooster. Impressive performance! Cheers!
Your an amazing thinker. You make me wish I had a 3D printer. Magnetic circuit, ✔️ 41 volts for 400 turns .2mm wire. What do you estimate the ampere generation would have been for the 41 volts? A resistor bank is used to protect coils in the wind turbines during overspin, where excess amperage can be disapated as heat. May also stop the blades from spinning. Next, Cylinder of serpentine stator and two magnet rotor cylinders as the cone inside of the Archemedes Screw.
Will a funnel shaped skirt at the rear smooth the vertices at the rear archimedes screw inprove the efficency and cut down on the vibrations and make the generator point into wind self steering ?
I have what might be a bit of an experiment for you. As you like using magnets, both natural and electro. Say You have a chamber that has two holes in it on either side. Not top or bottom, think front and back. There are valves to only allow the passage of air one way, so on the back it would only allow air into the chamber and on the front, it would only allow air out of the chamber. The valves could be simple flaps activated by pressure, no need to be fancy. Now, inside of the chamber there is a piston and as it moves up it pushes the air out, which would go out the front, and then as it lowers, it would draw air in through the back. Would you be able to put permanent natural magnets in the piston, and then on the top and/or bottom of the chamber have electro magnets that would attract and then repel the piston alternatively? Do You think it would work as a bellows? Would it be better than a regular fan or bellows? Would it be quieter?
Hi Robert, a couple of questions pop up for me with every one of these generator videos ... Why do you always put the magnets on the outside (far away from the coils) ? Surely closer is better ? And second question is whether you align the opposite poles of the magnets on opposite sides of the coil ?
Awesome! Now to a Question! if we take a serpentine coil and make to tracks! one north and one south! To got levitation on the permanent magnets have a magnet in the turn of the coil! this is the cheapest way to get a levitation bearing in the rim! And max output on it to! And we can get a row on the other side to! And if that is done i can see it work Vertical and Horizontal as an Bering! It might be more costly but real Good!!! / Mikael
That little turbine is just gorgeous, have you tried using capacitors in series to cancel the back-EMF generated in motors and the generator itself? Eliminating that little problem would be huge.
@@danedmiston9673 Have you experimentally verified that? Because that doesn't match what I've learned from studying Tesla and Steinmetz works, among others. The input torque of an electrical generator would free spin freely and indefinitely if not for 2 things, Friction and the Backwards Translation of Load in the form of a reverse magnetic field which forms as a result of the forward current, and which opposes the input motion. This reverse torque fighting the input torque requires more and more energy to be applied at the input to continue the ability for the extraction of energy at the output. Tesla spoke about this reverse current and reverse magnetic field, now called the Lenz Law. Tesla opposed the reverse torque natural occurrence, with the introduction of capacitors into an already inductive generator coil circuit. This is evident in the writing of Tesla's pancake coil patent. But more importantly he invented resonant electrical circuits, the resulting oscillations that occur within the same capacitive / inductive circuits, which alternately transmits magnetic and then dielectric pulses, over time, which each passing electrical half wave, and influence other similar circuits with the same electrical resonant frequency. The key here is that these secondary circuits are forced into electrical oscillation without a backwards translation of load, so long as the frequency remains perfect on both circuits. In other words, if you can keep the circuits resonating while you extract power from the second circuit, you will be able to withdraw more energy from the output than there is needed at the input to keep the system running. Then you can loop a portion of the output to power the input continuously and indefinitely. This has been successfully done and demonstrated in the work of Don Smith of Texas USA, and Tariel Kapanadze, of the soviet satellite country Georgia. The configuration is Tesla's patent 645576, System of Transmission of Electrical Energy. The configuration is Resonant circuits that are connected via the dielectric field. Although an optimal generator would be a lossless type that doesn't produce magnetism in its operation, instead maintaining lossless transmission in the form of dielectric current, this is how Tesla's hairpin circuit works by cleaning out the magnetism in an already inductive current, although I don't know if it's possible to generate pure dielectric current in the source. Although it's possible a generator that has had its back-emf suppressed via capacitive resonance is producing dielectricity instead of regular electricity, more research needed.
Rob, I just noticed in the video: The turbine and the wind meter are pointed in different directions. Maybe a wind vane on top of the wind meter will help
hey ive got two earlier dyson cordless vacuums only thing wrong with them is the battery. gonna fix one but the other.... was kinda thinking the motor might be good for a wind turbine? thoughts?
Hi there, very interesting channel. I actually am trying to print and assembling this turbine, but I think there is a missing part. In minute 1:43 when you are holding the serpentine part it is composed out of a blue part and a gray part. The gray part, which fits in the blue part doesn’t figure one the thingiverse files, or does it? Thanks for helping and greetings from Luxemburg
Really like this wind turbine, it reminds me of a pin-wheel. I could totally see a couple of these in the garden to power garden lights
It is astounding on how quickly and regularly you put out videos
cheers mate
Yes, i was wondering the same thing, pretty soon we will celebrate 2023 😊🎉!!
I agree with you, I don't see how he has time, I think he puts out a new one every day.

I'd love to see an Archimedes turbine mounted vertically inside a Darwin turbine. They look like they were made for eachother.
That was my first thought. It looks like it would be very efficient.
I also saw these as a match made in heaven 😊. Also because it would allow the use of the ball bearing tip to get low friction.
One thing I have found which is very important, is that these Neobidium magnets do not like being outside. If the surface coating is even very lightly scratched, the magnet just turns to rust dust.

Glad you are staying coreless with the generators.
That looks like a reverse impeller, the voltage output was impressive, I'm sure it is from running magnets on both sides of the coil.
why not create a machine that captures wind & solar energy?
Theres not enough surface area for solar cells to pick up sun properly plus if its a moving object the cells dont have enough time to pick up light and generate the energy properly. Good idea though.

That turns pretty good for the size of it. Can you attach a load and retest? Also, is there a max speed or some way to brake at a limit so it doesn't fly apart?
I love this concept
but getting it waterproof is a challenge
Of course it will spin and spin well Robert because your Awesome!! 🥳👍 Almost looks like a pin wheel @5:33 ..lol
That's impressive just for the fact that the highest wind speed at 2m/s is around half of the minimum required wind speed for a 3 blade turbine
A thing of beauty! Reminds me of a squid! What with the waistcoat and watch you are in danger of going full Dr. Who. It's a slippery slope. Take it from me! Perfect comic timing, tell the rooster. Impressive performance! Cheers!
wow, this is amazing, thank you so much
Excellent! Thanks muchly :) very interesting and well done.
Your an amazing thinker.
You make me wish I had a 3D printer.
Magnetic circuit, ✔️
41 volts for 400 turns .2mm wire.
What do you estimate the ampere generation would have been for the 41 volts?
A resistor bank is used to protect coils in the wind turbines during overspin, where excess amperage can be disapated as heat.
May also stop the blades from spinning.
Next,
Cylinder of serpentine stator and two magnet rotor cylinders as the cone inside of the Archemedes Screw.
The usual reply to these is "Try it out yourself, haha!"
Genius. I'd buy one of these for backpacking if it were made in a kit.
Thanks for sharing
Thanks for watching!
Will a funnel shaped skirt at the rear smooth the vertices at the rear archimedes screw inprove the efficency and cut down on the vibrations and make the generator point into wind self steering ?
Beautiful
Bless Up Fella
That's impressive.
Id love to test the power output on a dummy load
Awesome! Is the generator interfering with the air flow over the screw?
The Doctor Who look is complete!😂
Awesome generator!
Its hard for me to believe it could make more power than a 3 blade mill.
He is a "toy" maker.
You look like a kid with a brand new pinwheel. Nice design.
Thanks for another great one!
these could replace wind turbines, caged with wire, could not kill birds, and could be on top of every house like a wind vane. plz keep at it!
An aquatic variant would work well in the channels :O
I have what might be a bit of an experiment for you. As you like using magnets, both natural and electro. Say You have a chamber that has two holes in it on either side. Not top or bottom, think front and back. There are valves to only allow the passage of air one way, so on the back it would only allow air into the chamber and on the front, it would only allow air out of the chamber. The valves could be simple flaps activated by pressure, no need to be fancy. Now, inside of the chamber there is a piston and as it moves up it pushes the air out, which would go out the front, and then as it lowers, it would draw air in through the back. Would you be able to put permanent natural magnets in the piston, and then on the top and/or bottom of the chamber have electro magnets that would attract and then repel the piston alternatively? Do You think it would work as a bellows? Would it be better than a regular fan or bellows? Would it be quieter?
4:50 “… 0.9 m/s and it’s started to turn.” Now that _is_ something to crow about.
Hi Robert, a couple of questions pop up for me with every one of these generator videos ... Why do you always put the magnets on the outside (far away from the coils) ? Surely closer is better ? And second question is whether you align the opposite poles of the magnets on opposite sides of the coil ?
Awesome! Now to a Question! if we take a serpentine coil and make to tracks! one north and one south! To got levitation on the permanent magnets have a magnet in the turn of the coil! this is the cheapest way to get a levitation bearing in the rim! And max output on it to! And we can get a row on the other side to! And if that is done i can see it work Vertical and Horizontal as an Bering! It might be more costly but real Good!!! / Mikael
That little turbine is just gorgeous, have you tried using capacitors in series to cancel the back-EMF generated in motors and the generator itself? Eliminating that little problem would be huge.
The "back-EMF" is what makes it a generator, the more the better.
@@danedmiston9673 Have you experimentally verified that? Because that doesn't match what I've learned from studying Tesla and Steinmetz works, among others.
The input torque of an electrical generator would free spin freely and indefinitely if not for 2 things, Friction and the Backwards Translation of Load in the form of a reverse magnetic field which forms as a result of the forward current, and which opposes the input motion. This reverse torque fighting the input torque requires more and more energy to be applied at the input to continue the ability for the extraction of energy at the output.
Tesla spoke about this reverse current and reverse magnetic field, now called the Lenz Law. Tesla opposed the reverse torque natural occurrence, with the introduction of capacitors into an already inductive generator coil circuit. This is evident in the writing of Tesla's pancake coil patent. But more importantly he invented resonant electrical circuits, the resulting oscillations that occur within the same capacitive / inductive circuits, which alternately transmits magnetic and then dielectric pulses, over time, which each passing electrical half wave, and influence other similar circuits with the same electrical resonant frequency.
The key here is that these secondary circuits are forced into electrical oscillation without a backwards translation of load, so long as the frequency remains perfect on both circuits. In other words, if you can keep the circuits resonating while you extract power from the second circuit, you will be able to withdraw more energy from the output than there is needed at the input to keep the system running. Then you can loop a portion of the output to power the input continuously and indefinitely. This has been successfully done and demonstrated in the work of Don Smith of Texas USA, and Tariel Kapanadze, of the soviet satellite country Georgia.
The configuration is Tesla's patent 645576, System of Transmission of Electrical Energy. The configuration is Resonant circuits that are connected via the dielectric field.
Although an optimal generator would be a lossless type that doesn't produce magnetism in its operation, instead maintaining lossless transmission in the form of dielectric current, this is how Tesla's hairpin circuit works by cleaning out the magnetism in an already inductive current, although I don't know if it's possible to generate pure dielectric current in the source.
Although it's possible a generator that has had its back-emf suppressed via capacitive resonance is producing dielectricity instead of regular electricity, more research needed.
Rob, I just noticed in the video: The turbine and the wind meter are pointed in different directions. Maybe a wind vane on top of the wind meter will help
Love this project!
awesome!
intriguing, thank you 🖐️
hey ive got two earlier dyson cordless vacuums only thing wrong with them is the battery. gonna fix one but the other.... was kinda thinking the motor might be good for a wind turbine? thoughts?
An aquatic variant would work well in the channels :O
Hi there, very interesting channel. I actually am trying to print and assembling this turbine, but I think there is a missing part. In minute 1:43 when you are holding the serpentine part it is composed out of a blue part and a gray part. The gray part, which fits in the blue part doesn’t figure one the thingiverse files, or does it?
Thanks for helping and greetings from Luxemburg
thanks, without the plate with the magnets behind the coil how much less does it produce?
