me to. Robert, i would appreciate a generator test some time, - with and without an iron core, because your channel and audience stays awesome, and needs too see the comparison, in your style.
Put up a tall pole with a star shaped support and have several of those supports running down the pole with 5 of those turbines at the end of each star shaped support, then link them together in an electrical hub to produce quite a bit of energy. I hope you understand what I am saying. You have a great idea there and if done right, you can make a great deal of money there!
Imagine telling a kid (or adult for that matter) in the 70’s that you are “just going to print something”, no not a letter on the daisy wheel printer, a solid useable object ! Those 3D printers have certainly found a home amongst your other traditional workshop tools.
@@andrewsmithmilan1780 Would it be possible to assemble the fins that were printed separately that could be locked together.

I think it's more accurate to say that wind turbines typically come in 2 primary form factors, and the one you didn't mention, Vertical Axis Wind Turbine (VAWT) is also omnidirectional. It would be interesting to see this ball design vs equivalent scale HAWT and VAWT designs for starting windspeed, survival windspeed, noise, and power generation curve
VAWTS are no more omnidirectional than HAWTS. Both can make energy from wind blowing in any horizontal direction. Neither can make energy from wind blowing upwards or downwards, which this one can. But the wind doesn't blow that way so that's not something people usually design for
Actually wind can blow up or even down along the edge of a roof and in front of an obsticle, and even at the end of a dead end ally. Congrats to Robert.
@@ulgencutube In truth, there are also so-called katabatic winds and those who go sailing know this and fear them because they put spreaders in the water; but these are not winds that can be used to produce electricity. In truth there are also winds that go upwards, the well-deserving thermals that glider pilots know well and look for but even these cannot be used to produce electricity, which is in truth Robert's objective.
Pure genius Sir! This is such a brilliant idea. If only there was a UPS that could take an external DC input and go into "off grid mode" on the fly. Cheers from across the pond
Would scaling up increase output? It would be ideal for boats that often have small wind turbines to generate electricity. It wouldn't need a vane, just a bearing on the support.
Well I was going to mention setting the double blade generator at 15° angle to the wind allowing more power to be extracted discovered by the Jacobs wind power company. Now this may remove the tilt as an option with the ball generator.
Mr. Smith, you are a very good teacher, you lead by example and are an inspiration to me personally. i am spending more and more of my time on your channel and i hope to soon make a turbine based on your designs. Because of your channel i am also studying 3D printing with the intention of buying a 3d printer. I hope to be your student for some time to come. Thank you
Since it's roughly round, it could be mounted inside one of those nose bump things some older semi trucks put on their front grille to help aerodynamics; the air pressure creates enough of a laminar flow across the surface of it that it should ignore the turbine and see it as mostly a smooth surface. Until it's going fast enough for it to build up enough pressure to create that effect, it's not going fast enough to make a difference and is still generating the whole time without adding to, but improving, drag.
Evolution of vertical generators: Savinius -> Ugrinsky -> C-rotor -> Darieus. Until the omnidirectional Darieus rotor with rotation in opposite directions has been tested - all these are just toys
WOW, that's the ticket! 🙌 I love the conscientious design and the fact that it is omnidirectional. I believe the output losses are completely worth safety and portability. Thanks for sharing this awesome design with us. ✌️ Have a wonderful day Rob!
I love it! Install a sequence of them in a pvc tube with your Rose air screw at the upper end, hand crank your Rose to "start the siphon" and it should draw air through the tube spinning a number of tiny power generator spheres.
Thank you, amazing work. Your idea is very wonderful. It is spherical in shape and will also rotate if you place it vertically, and perhaps then if you lower the spacer in the middle and make it with one flow of the blades from the top of the ball to the bottom, it will rotate as is the case in fireplace fume hoods.
This is a perfect design for people without a 3D printer to copy or enlarge using standard materials like plywood (marine or standard) and careful building to maintain balance and strength. If enlarged it should be able to use 6 wings with evenly distributed magnets between them as well as lower edge support. It would appear that the diameter of the ball is about 100 to 125mm, comparing it to Robert's hand width.
Robert is like a virus: when you can't find the original key, make something that looks like it, change it by 'bits 'n' bobs,' with the best tools available, until you feel that satisfying click.
@@mikeyb7263 I AGREE WITH YOU ABSOLUTELY,,,, AGAIN!!😁 (PLEASE FORGIVE THE SHOUTING, & SPELLING MISTAKES,,,PROBLEMS WITH KEYVOARD AND LOSS OF SPECS) AFFORDABILITY AND UTILITY ARE THE WAY I HAVE TO VIEW EVERYTHING AS WELL.🙂
Speaking of things being "the best", this is one of the best videos I think you've made. But don't let that stop you making something even better! This is going to be my next project. Now time to order some wire and magnets!
Very good exploring different methods Low wind speeds less than 1 m/sec is what we are working toward testing that is difficult I personally do not like tests performed with wind by hair drier or a fan
What interests me most about the object, taking its effective efficiency for granted, are its small dimensions. This belief could solve the dimensional problem that is blocking one of my projects. Therefore I ask Roberte if it is possible to buy one. I trust in the courtesy of positive feedback. I have always loved the genius of the simple and this is an excellent example of it.
Especially if the leds are whizzing around on the blade itself, with only the magnets being stationary, it would look like an arc reactor, seizure warning may be in order tho 😅
lol the end keep me up with what your doing lately , i have good results adding 2" inch foamboard insulation on the outside , i use 2" cut piece of 3/4" pex pipe for spacer , i use i think 1" hole saw with the bit removed from the center , and core spots where the pex goes into the foam i roll some thin foam on the pex and fill the spacer with foam from the hole saw and use 3 1/2" inch decking screw or stainless with a 1/4" inch washer so i paint the foam with roof tar for the heck of it and add those spacers on the edge , then i used 1/2" cement board in 3x5 foot sheets cut to screw over the foamboard with the spacer and the washer over the cement board , so i take a one quart acrylic stucco patch (they have acrylic cement or concrete repair too but i use stucco patch acrylic one quart dries white ($9 , $7 prebidenflation ) and up to half acrylic white paint or whichever i did purple and it goes thru the plaster (same color if scratched) ....cement board is not rated exterior but i figure it isn't exterior with the acrylic cement , i used regular thinset layer between for filler on this one ....i have some block post stuff i'll build soon sort of like pole barn stuff but with block posts, columns i guess .....i've been digging a trench and pouring 4 gallons of taurus sc fipronil in it for bug damage because i have emergency restorations going on i take breaks to go online a lot because the heat lately ,,, i hope i'll get it done fast because i have sheds to rebuild and i might make a post beam 12' foot by 12" foot guest room up on posts but i'll cover it with seashells maybe and same method foamboard , cement board , 6x6 posts , metal roof the dimension is for no permit where i live ... hopefully i'll get some bigger actual tech type projects going out of my metalshop soon but i have big projects ,cars a boat motorcycle truck etc everythign becuase i getting back in shape from being blind still
urgh lol thing is for across outer walls i have the inside stripped and i use 4" foamboard for r20 the wall studs are about r1 per inch (wood) so it's riddles cover those too but i can add 2" furring strips horizontally across right thru the siding and into each wall stud for lateral strength , creates a much stronger wall !!! (edit: the studs this method only not covered with foam where the furring stip bolts on through from exterior and add 2" R10 extra with 2 1/2" thicker outer ....the concept of stucco involves leaving space at the bottom for drainage if water somehow was in the wall and it uses support blocks spaced on the ground so i'm adding footer wall , built in resting spots , can add standard stucco layer thicke rin future or brick very versatile/ mssg too long again lol
Those are brilliant for any small homestead or off-grid barn! Just set a few rows of them on your roof, the spacing doesn't look to be that important, as long as they aren't touching, me thinks. The teaching about the distance from the Multi-Rotor of a quarter of a rotor length should perhaps still be adhered to, shouldn't it? In this case maybe a quarter of the ball diameter? About the Multi-Rotor, btw: If you add another set of Rotor blades, a quarter of the blade length spaced out on an axle and 2nd&3rd equally spaced out in angle, would that 3rd set of blades add to the strength of wind generator? Or would it be detrimental? Because a 3rd set would, if not detrimental to the power generation, simultaneously act as a wind wane to keep the Rotors in the wind as well as the possibility to add in power generation
Super interesting as always Robert! Have you considered creating a leaderboard with the test results for all the different types of wind turbine you've made so far? I suppose it might be tricky to compare some of them since they're different sizes though.
And he would need a controlled, constant wind testing setup, so that means inside testing only with a big fan of some sort to simulate wind. But that would be amazing to see the results for each current turbines and futures ones.
@@ThinkingandTinkering I've seen similar tests / ratings being done for novel computer fan blade designs (on RUclips), and it seems valuable not only as data but as content.
fine design, finally printed and assembled one. Only managed to lay 65 windings of 0.3! Gives max 2V with a hair dryer and even wit gale-force PIA it barely turns . Had expected more from it. We are looking for something better. 'Twas nice to try
Will this be going at the bottom of the Darwin wind turbine? Would love to see what’s the best for the DWT whether it’s the cone, flower or double propeller.
I like this, much less drag than whirring blades, much lower profile, so potential to be put in lots of places and gather energy, the design lends itself to being moulded, so cheaper to make, especially at larger scale. Some airflow dynamics clever sausage, should run simulations of this at different scales, to understand more about what power could be generated for different sizes and optimize the design. on a larger scale, you could use the space in each hemisphere to house batteries and also have a storage solution.
The vertical Helical wind turbine is another good design and also an 360 degree wind flow usage. Not omni directional but since most wind travels in a relative plane to the ground then it works well enough. It can sit low to objects and not have the giant blades and can self balance itself and not self destruct like the big ones do. Can also have a extra brake on the shaft because it can have 2 points of holding, top and bottom. Those 2 points can give a fair bit of room for everything. Omnidirectional would be good on mobile platforms like cars, RVs and even busses. Mostly for when they are just sitting around, they can help with some recharging instead of just relying on main charging. They can also power something remotely like a trailer and even while in use so it would cut down wiring to the main vehicle. Heck these things could be positioned onto Telephone poles up in the air spinning away without causing too much harm to the surrounding. Given the number of poles like that in just a town alone, it would give a pretty healthy energy charge any time of the day.
I'm thinking of a hybrid, with a hemisphere made as the nose-cone for the dual blade turbine but it's possible that'd interfere with the airflow too much, making it more efficient at some windspeeds and less efficient at others, the trick would be tuning it to fit the most common/expected windspeeds for it's sighting.
Yet another item of interest! I wonder if there is any benefit in having the blades opposing? You have holes in the "base" so air can go from one side to the other. With opposing blades this would cause a loss in the tailing blade, but if it were reversed you would get effectively two blades working in tandem (even if they will stop and reverse when the wind changes direction. To be honest the wind rarely does a full 180 very often! Eather way, cheers for making me think!
@@ThinkingandTinkering That is what I said. Could the airflow Through give extra input from the trailing blade if it is the handedness of the blades were correct!
I found it a great place to start when trying to make things better....simply mirroring how it was made tends to work better... I guess that shouldnt be as surprising in an upside down clown world! Lol! Great video man!
I dont know if the air flow reacts the way we think it does instinctively. It seems like this type of "turbine" desing reacts more to the preassure changes instead of the flow. It seems to me like this is why it is omnidirectional. Maybe mix both types in one desing into one turbine? (Directional and omnidirectional). One must be more efficient to put in front of the other. Maybe new record efficiency threshold lies abit further down your road!
Wonder if that would reduce the laminar flow requirement for the more standard wind turbine design. If it does, that would make a massive difference to the energy production of most farms, where the distance between turbines and orientation of turbine relative to the dominant wind direction are major limiting factors.
have you tested installing wind turbine on roof and putting something around it to accelerate the wind speed? like something where you concentrate large amount of wind into small wind turbine. i think that could be a cost effective solution.
even though it's bidirectional it seem to have a most efficient angle that the wind should be blowing on to ... I would THINK its straight onto the face of the spiral, (more testing is needed to prove this true) and if this is the case then the other spiral is nothing but dead weight.... so if you were to put a bearing on the pole so it could rotate around, and put arm with vertical fin this would steer it so the spiral is always facing straight onto the wind..... and of course there's no need for the other spiral at this point so it could be removed... OR another piece that CONTINUES the spiral onto the other side would create more surface area and catch more wind, spinning it faster..... so it's still omnidirectional but you could create a larger diameter AND you could even design that secondary spiral to be the optimal shape according to fluid dynamic principles (sort of like how there have been new propeller designs created for boats that were designed in computer programs that no one had thought would be of any improvement but turned out to VASTLY increase performance.... they sort of look like loops and are complete counter intuitive looking lol - I just looked it up and they're called toroidal propellers ) - oh and I'm just spitting out thoughts that come to mind when I see your amazing creations... I'm not trying to tell you to do this or that, or to say it would be better if you did it this was or that.... maybe they'll inspire you to come up with a new idea or maybe I'm just getting annoying (don't hesitate to tell me to stfu LOL) - Have you looked into torodial propellers on the channel before? ( I can't say I've watched all 2000+ videos since I discovered your channel a few weeks ago LOL ) if you haven't maybe it's something you might want to explore
Robert.. Looking again at this design, I am reminded of old ideas of ours to play with water prop designs. This design with the update where you hollowed out the blades I rekon could be a good prop design for boats.
if you dont link the magnets together but instead offset one side of them to fill the gap between two magnets on the opposite rotor and reverse polarity of the magnets you could essentially simulate double the speed of the rotor. Right rotor N hits coil 1->left rotor S hits coil 1->right coil N coil 1. Left rotor magnet should sit in the gap between the right rotor magnets 1 and 2. One side all S one side all N magnetic field would hit the coil twice as much in one complete rotation
Robert, very interesting... Could you build one of these at the same size as the bladed version to test and see which one is more efficient at different wind speeds etc..
Hmm. The propeller blades are mirror images of each other, meaning they'll spin in the same direction. Laminar flow from the right side to the left side along the axle would dictate that the propellers be reversed images rather than mirror images for better air movement through the device. I also wonder if it would be possible to counter-rotate one side relative to the other...
contra rotation isn't a good idea mate the magnets would in effect cancel each other out for 180 degrees of turn halving the output and it would introduce cogging raising the start wind speed
@@ThinkingandTinkering Hmm. Okay, that makes sense. I was thinking of gearing where if you have to counter-rotating objects, their speed relative to each other would be double that of whatever is driving it since they're spinning against each other.
@@christopherd.winnan8701 Sure thing. Take a look at the spiral on the left side. Then the spiral on the right. They mirror each other in the middle. If it was a reversed image, the spiral would look like it continues through both sides, rather than get to the middle and then reverse. So, in my mind, a reversed image is a mirror image flipped along the horizontal plane. I thought that if the spiral was continuous through both sides, the wind would have an easier time flowing through, rather than hitting a wall in the middle and having to divert 90° at the spiral on the other side.
it is good thinking mate and i get where you are coming from but with axial flux like this it would be counter productive - i think - but that is only what I think - you could always give it a go and see how it works for you - cheers mate and keep the ideas coming
That is very much along the lines of the LIAM F1. Now, I couldn't see how much voltage it was putting out... but I'm sure multiples could be the ticket! Any idea what the wind speed of the hair dryer being used???
I would love to see you explore coils and power generation. So, undert the same input power, how do different coils behave? Serpentine the best? size of wire? number of turns? all underst the same spin rate. That would tell us a lot about how best to make the type of electricity we need, high voltage or high amperage. Figuring out which types of coils, how many turns, how think the wire, how the shape impacts it, etc. strenth of magnets.
Hi Robert, I disciver your channel yesturday, and what you share is absolutly amasing. It also unlock some questions in my own experimentation I’m actually doing on searching new kind of turbine ! :) Hope I can share it with you when I will finalise it !
I love this design, I am going to print a few and configure them as "fruit" hanging from a generator tree. I think I may use it to charge some batteries for a streetlight idea. One question, how long of a coil do I need to make?
About 25 years ago my dad made an omni-directional turbine for pipes. It looks kind of like if the Predator designed a volleyball. Not sure what happened to it. He made his greatest success when he made a special structure that converts the energy of small waves into vertical height so that you can create a gravity feed of sea water into estuaries so that the estuary stays healthy and then the device managed to be used for the same functionality but to create a water turbine from constant waves. It's just a ramp but it has unique angles that amplify the wave into the right compression so that the wave can clear extra height. The Australian and German governments were going to build a lot of them but I guess then the pioneers of the WEF shut it down because it was too simple and effective. Just floating concrete ramps.
If we are worried about flying animals going into the blades, have we tried putting a mesh over the front and seeing if there is a drop in power? Also how big can we go? Looks good to me. 👍
Magnetic fields are always between a north pole and a south pole - so the north poles on one side will link up to the south poles on the other and vice versa. That will cause them to move together, and also cause the magnetic field to pass straight through the coil as they rotate, which is what you want.
It seems like the counter-rotating blades would be great atop a stack of your lateral wind harvesters (Darwin / Ventum), as that would maximize the efficiency of the blades while diminishing their potential harm against wildlife. But I can also visualize a large ball or omnidirectional "blade" above the same stack. I wonder if the omnidirectional blade catching wind from the side, but also being above a stack that is driving wind up, would have benefits? For one, it should operate in lower air speeds due to the stack concentrating air flow. A second benefit is it might also be more stable in higher winds (up to a point). But ... are there hidden problems to be discovered in the implementation?
Such an interesting result, a horizontal turbine that is a vertical turbine. Did like someone's suggestion to move the generator completely out of the wind flow. But there is another option, move the blades past the edge of the generator.
@@ThinkingandTinkering I was, like the other comment, thinking about the wind flow. In this instance trying to get some wind coupling where the blades had the largest leverage.
With the same size and design of the generator part, how does the energy production compare with conventional blades when going against a wide enough wind "surface" to hit the whole thing evenly? (perhaps you could test it by mounting them on the back of a pickup truck, one on each side to get the readings simultaneously symmetrically), and then drive back and forth a few times to get an average and cancel out the effects of crosswind on the conventional blades? Also, does this design produce the same amount of energy with wind coming from all directions, when the wind "surface" is large enough to hit the whole thing?
Robert, my friend went to India for a vacation. He told me the the people in that country are so wind crazy that you can see vertical wind machines as far as you eye can see spinning in the wind. This has to be one of the most important energy making machine PERIOD !!!! This is a very special unit to save a ton of money for energy used by anyone. Well done fella. Peace vf
Keep up the great work fella. I know a many who use your knowledge to make free energy producing devices. Well done fella too. vf@@ThinkingandTinkering
Would you be willing to try using round neodymium magnets as external ball bearings on the outer rim of the wind turbine spinning inside of the coil? My hypothesis is two fold. Firstly, that the magnets will polarly lock to each other and not roll unless under the correct amount of pressure and friction and then will roll as a tidy locked force. Alternatively spacing them out and allowing them to roll will both increase and interfere with the magnetic field cohesion within the coil. Perhaps ovals that could roll within thus accentuating the potential field motion dynamics. Perhaps being tunable to something akin to grouped vortexes as a sustained vortex wall to the larger field... For stabilization of such a field, the inputs would have to be rotationally quantified to the coanda effect, perhaps a few strands of appropriately shaped electromagnets to be stimulated on the individual strand level.
Dear Robert, thank you for your next great video. For the next one, I recommend putting it in front of the measurement device big magnifying screen so the numbers measured are better readable
Thank you for all your videos and your ideas. I love watching the videos. I am very interested in making a wind turbine that would generate enough power to run a heater ~ 5KW. Your ideas are great, but how would one go about scaling up the size to put the concept into practice, in an economical way. Thanks.
You know that would work near the ground in high turbulence and low wind velocities. It would cost almost nothing to maintain. It may not have the highest theoretical efficiency, but I bet it can flat out generate any normal wind turbine for the same size over a year, and cost less.
Great build. Have you considered combining The Darwin collector and having the air stream come in to the edge of a Tesla turbine. Air flow exits the center to capture all the energy with the stacked disks in the laminar flow?
Asked to scale what was the speed of that wind.? the hairdryer blows a lot more forcefully than regular wind naturally. This looks a little too bulky to produce naturally. We need a low speed turbine that can generate wind when it is not blowing. We also need a a solar panels that produces on the sun is covered with clouds.
My understanding is when wind turbines are in high or I guess dangerously high winds they can generate too much energy and have catastrophic failures, I am wondering if regenerative braking technology like what is used in Ev's could be used to slow wind turbines as well as still collect energy all while keeping wind turbines from failing in conditions that can push a wind turbine into a critical state? maybe their are wind turbine companies already thinking about or implementing an idea like this if is possible or even viable.

lol - nice one mate lol
Speaking of things being "the best", this is one of the best videos I think you've made. But don't let that stop you making something even better!
This is going to be my next project. Now time to order some wire and magnets!
Very good exploring different methods
Low wind speeds less than 1 m/sec is what we are working toward testing that is difficult
I personally do not like tests performed with wind by hair drier or a fan
Neat. I wonder what kind of airflow patterns it would generate if you powered it as a motor.
no idea mate
@@ThinkingandTinkering submit it to the fan showdown, here on RUclips!
What interests me most about the object, taking its effective efficiency for granted, are its small dimensions.
This belief could solve the dimensional problem that is blocking one of my projects.
Therefore I ask Roberte if it is possible to buy one.
I trust in the courtesy of positive feedback.
I have always loved the genius of the simple and this is an excellent example of it.
Brilliant! Love it! Stick it in a gyroscope with self contained led's and stick it on a pole! Call it a street lamp from 2077
Especially if the leds are whizzing around on the blade itself, with only the magnets being stationary, it would look like an arc reactor, seizure warning may be in order tho 😅
lol
I mean, there are already vertical turbines, and they are equally efficient regardless of wind direction.
indeed there are - not sure what your point is mate
A series of them on a house roof ridge feeding into a battery would be brilliant. Better still could this charge up a sand battery ??
Both. Use the Sand Battery as the "Dump load" for when the batteries are full.
Timesurfer is spot on mate
lol the end keep me up with what your doing lately , i have good results adding 2" inch foamboard insulation on the outside , i use 2" cut piece of 3/4" pex pipe for spacer , i use i think 1" hole saw with the bit removed from the center , and core spots where the pex goes into the foam i roll some thin foam on the pex and fill the spacer with foam from the hole saw and use 3 1/2" inch decking screw or stainless with a 1/4" inch washer so i paint the foam with roof tar for the heck of it and add those spacers on the edge , then i used 1/2" cement board in 3x5 foot sheets cut to screw over the foamboard with the spacer and the washer over the cement board , so i take a one quart acrylic stucco patch (they have acrylic cement or concrete repair too but i use stucco patch acrylic one quart dries white ($9 , $7 prebidenflation ) and up to half acrylic white paint or whichever i did purple and it goes thru the plaster (same color if scratched) ....cement board is not rated exterior but i figure it isn't exterior with the acrylic cement , i used regular thinset layer between for filler on this one ....i have some block post stuff i'll build soon sort of like pole barn stuff but with block posts, columns i guess .....i've been digging a trench and pouring 4 gallons of taurus sc fipronil in it for bug damage because i have emergency restorations going on i take breaks to go online a lot because the heat lately ,,, i hope i'll get it done fast because i have sheds to rebuild and i might make a post beam 12' foot by 12" foot guest room up on posts but i'll cover it with seashells maybe and same method foamboard , cement board , 6x6 posts , metal roof the dimension is for no permit where i live ... hopefully i'll get some bigger actual tech type projects going out of my metalshop soon but i have big projects ,cars a boat motorcycle truck etc everythign becuase i getting back in shape from being blind still
urgh lol thing is for across outer walls i have the inside stripped and i use 4" foamboard for r20 the wall studs are about r1 per inch (wood) so it's riddles cover those too but i can add 2" furring strips horizontally across right thru the siding and into each wall stud for lateral strength , creates a much stronger wall !!! (edit: the studs this method only not covered with foam where the furring stip bolts on through from exterior and add 2" R10 extra with 2 1/2" thicker outer ....the concept of stucco involves leaving space at the bottom for drainage if water somehow was in the wall and it uses support blocks spaced on the ground so i'm adding footer wall , built in resting spots , can add standard stucco layer thicke rin future or brick very versatile/ mssg too long again lol
Those are brilliant for any small homestead or off-grid barn! Just set a few rows of them on your roof, the spacing doesn't look to be that important, as long as they aren't touching, me thinks.
The teaching about the distance from the Multi-Rotor of a quarter of a rotor length should perhaps still be adhered to, shouldn't it? In this case maybe a quarter of the ball diameter?
About the Multi-Rotor, btw: If you add another set of Rotor blades, a quarter of the blade length spaced out on an axle and 2nd&3rd equally spaced out in angle, would that 3rd set of blades add to the strength of wind generator? Or would it be detrimental?
Because a 3rd set would, if not detrimental to the power generation, simultaneously act as a wind wane to keep the Rotors in the wind as well as the possibility to add in power generation
A third set would be an interesting experiment, as would trying one of the new globe designs stuck out as a rear fin.
cheers mate and i would think so - but i am not sure
roberts windmill shop, looks like a big seller. good video
cheers mate
Hm...a "Wind Wall" of those could be very interesting! ;)
yes it would
That satisfied smile and laugh made me happy for you :) Good work!
I think if this was on an axis like a regular wind turbine with a wind vane, it could be even more efficient.
for sure
Super interesting as always Robert! Have you considered creating a leaderboard with the test results for all the different types of wind turbine you've made so far? I suppose it might be tricky to compare some of them since they're different sizes though.
And he would need a controlled, constant wind testing setup, so that means inside testing only with a big fan of some sort to simulate wind. But that would be amazing to see the results for each current turbines and futures ones.
no mate i haven't considered that
@@ThinkingandTinkering I've seen similar tests / ratings being done for novel computer fan blade designs (on RUclips), and it seems valuable not only as data but as content.
fine design, finally printed and assembled one. Only managed to lay 65 windings of 0.3! Gives max 2V with a hair dryer and even wit gale-force PIA it barely turns . Had expected more from it.
We are looking for something better. 'Twas nice to try
Hi Robert, great design, would be handy as a comparison on the hill with the dual blade design at the same wind speed
Will this be going at the bottom of the Darwin wind turbine? Would love to see what’s the best for the DWT whether it’s the cone, flower or double propeller.
not this one mate
This resembles Liam F1 wind turbine. You should definitely check that out if you haven't already. It would be interesting to see a diy version of it.
I like this, much less drag than whirring blades, much lower profile, so potential to be put in lots of places and gather energy, the design lends itself to being moulded, so cheaper to make, especially at larger scale. Some airflow dynamics clever sausage, should run simulations of this at different scales, to understand more about what power could be generated for different sizes and optimize the design. on a larger scale, you could use the space in each hemisphere to house batteries and also have a storage solution.
The vertical Helical wind turbine is another good design and also an 360 degree wind flow usage. Not omni directional but since most wind travels in a relative plane to the ground then it works well enough. It can sit low to objects and not have the giant blades and can self balance itself and not self destruct like the big ones do. Can also have a extra brake on the shaft because it can have 2 points of holding, top and bottom. Those 2 points can give a fair bit of room for everything.
Omnidirectional would be good on mobile platforms like cars, RVs and even busses. Mostly for when they are just sitting around, they can help with some recharging instead of just relying on main charging. They can also power something remotely like a trailer and even while in use so it would cut down wiring to the main vehicle. Heck these things could be positioned onto Telephone poles up in the air spinning away without causing too much harm to the surrounding. Given the number of poles like that in just a town alone, it would give a pretty healthy energy charge any time of the day.
What do you think the sweet price point will be for rapid consumer adoption?
cheers mate
Nice one Mate! Now you have a 3d printer can you explore the Lily prop?
I already did mate
I'm thinking of a hybrid, with a hemisphere made as the nose-cone for the dual blade turbine but it's possible that'd interfere with the airflow too much, making it more efficient at some windspeeds and less efficient at others, the trick would be tuning it to fit the most common/expected windspeeds for it's sighting.
that would make an awesome investigation mate
Yet another item of interest!
I wonder if there is any benefit in having the blades opposing? You have holes in the "base" so air can go from one side to the other. With opposing blades this would cause a loss in the tailing blade, but if it were reversed you would get effectively two blades working in tandem (even if they will stop and reverse when the wind changes direction.
To be honest the wind rarely does a full 180 very often!
Eather way, cheers for making me think!
The wind always does a 180degree shift when I am turning round to go home on my bike
@@davidmunro2077 May the wind blow gently on your back! ?
there are holes mate - check out the drawing
@@ThinkingandTinkering That is what I said. Could the airflow Through give extra input from the trailing blade if it is the handedness of the blades were correct!
I found it a great place to start when trying to make things better....simply mirroring how it was made tends to work better... I guess that shouldnt be as surprising in an upside down clown world! Lol!
Great video man!
Excellent! lol
I dont know if the air flow reacts the way we think it does instinctively. It seems like this type of "turbine" desing reacts more to the preassure changes instead of the flow. It seems to me like this is why it is omnidirectional.
Maybe mix both types in one desing into one turbine? (Directional and omnidirectional). One must be more efficient to put in front of the other. Maybe new record efficiency threshold lies abit further down your road!
we keep looking mate!
Wonder if that would reduce the laminar flow requirement for the more standard wind turbine design. If it does, that would make a massive difference to the energy production of most farms, where the distance between turbines and orientation of turbine relative to the dominant wind direction are major limiting factors.
Similarities to the blade less hydro turbine; cool beans
cheers mate
Brilliant little video once again, keep them coming looking forward to the next omnidirectional ball video.👍👏
have you tested installing wind turbine on roof and putting something around it to accelerate the wind speed? like something where you concentrate large amount of wind into small wind turbine. i think that could be a cost effective solution.
He has talked about this subject in earlier videos, even made a design to take advantage of it.
yes
even though it's bidirectional it seem to have a most efficient angle that the wind should be blowing on to ... I would THINK its straight onto the face of the spiral, (more testing is needed to prove this true) and if this is the case then the other spiral is nothing but dead weight.... so if you were to put a bearing on the pole so it could rotate around, and put arm with vertical fin this would steer it so the spiral is always facing straight onto the wind..... and of course there's no need for the other spiral at this point so it could be removed... OR another piece that CONTINUES the spiral onto the other side would create more surface area and catch more wind, spinning it faster..... so it's still omnidirectional but you could create a larger diameter AND you could even design that secondary spiral to be the optimal shape according to fluid dynamic principles (sort of like how there have been new propeller designs created for boats that were designed in computer programs that no one had thought would be of any improvement but turned out to VASTLY increase performance.... they sort of look like loops and are complete counter intuitive looking lol - I just looked it up and they're called toroidal propellers ) - oh and I'm just spitting out thoughts that come to mind when I see your amazing creations... I'm not trying to tell you to do this or that, or to say it would be better if you did it this was or that.... maybe they'll inspire you to come up with a new idea or maybe I'm just getting annoying (don't hesitate to tell me to stfu LOL)
- Have you looked into torodial propellers on the channel before? ( I can't say I've watched all 2000+ videos since I discovered your channel a few weeks ago LOL ) if you haven't maybe it's something you might want to explore
it will do and you are right the answer is more testing
Always love the laugh of admiration at the universe showing us a fun time
the world is an awesome place!
Robert.. Looking again at this design, I am reminded of old ideas of ours to play with water prop designs. This design with the update where you hollowed out the blades I rekon could be a good prop design for boats.
It looks like the combined windmill/generator should work great in high winds. Can't imagine that it will turn in light winds.
if you dont link the magnets together but instead offset one side of them to fill the gap between two magnets on the opposite rotor and reverse polarity of the magnets you could essentially simulate double the speed of the rotor.
Right rotor N hits coil 1->left rotor S hits coil 1->right coil N coil 1.
Left rotor magnet should sit in the gap between the right rotor magnets 1 and 2.
One side all S
one side all N
magnetic field would hit the coil twice as much in one complete rotation
Robert, very interesting... Could you build one of these at the same size as the bladed version to test and see which one is more efficient at different wind speeds etc..
Hmm. The propeller blades are mirror images of each other, meaning they'll spin in the same direction. Laminar flow from the right side to the left side along the axle would dictate that the propellers be reversed images rather than mirror images for better air movement through the device. I also wonder if it would be possible to counter-rotate one side relative to the other...
Could you explain the difference between a mirror image and a reversed image please?
How would you set up the gearing for counter-rotation?
contra rotation isn't a good idea mate the magnets would in effect cancel each other out for 180 degrees of turn halving the output and it would introduce cogging raising the start wind speed
@@ThinkingandTinkering Hmm. Okay, that makes sense. I was thinking of gearing where if you have to counter-rotating objects, their speed relative to each other would be double that of whatever is driving it since they're spinning against each other.
@@christopherd.winnan8701 Sure thing. Take a look at the spiral on the left side. Then the spiral on the right. They mirror each other in the middle. If it was a reversed image, the spiral would look like it continues through both sides, rather than get to the middle and then reverse. So, in my mind, a reversed image is a mirror image flipped along the horizontal plane. I thought that if the spiral was continuous through both sides, the wind would have an easier time flowing through, rather than hitting a wall in the middle and having to divert 90° at the spiral on the other side.
it is good thinking mate and i get where you are coming from but with axial flux like this it would be counter productive - i think - but that is only what I think - you could always give it a go and see how it works for you - cheers mate and keep the ideas coming
This is Genius, so glad I found your channel.
Where are all the big guys doing this..?
cheers mate
Would have been interesting to measure the output power of that turbine. A good idea nonetheless.
cheers mate
If you run them like motors, what's the pattern of the wind they produce around them?
no idea
That is very much along the lines of the LIAM F1. Now, I couldn't see how much voltage it was putting out... but I'm sure multiples could be the ticket! Any idea what the wind speed of the hair dryer being used???
The last configuration was hanging around 8v
around 8v
I would love to see you explore coils and power generation. So, undert the same input power, how do different coils behave? Serpentine the best? size of wire? number of turns? all underst the same spin rate. That would tell us a lot about how best to make the type of electricity we need, high voltage or high amperage. Figuring out which types of coils, how many turns, how think the wire, how the shape impacts it, etc. strenth of magnets.
Hi Robert, I disciver your channel yesturday, and what you share is absolutly amasing. It also unlock some questions in my own experimentation I’m actually doing on searching new kind of turbine ! :)
Hope I can share it with you when I will finalise it !
Seems efficient compared to its size , well made , all the best . 🙏🏻
it seemed to do ok for sure - cheers mate
Love your enthusiasm for success, Rob. 👍👍👍
cheers mate
That design would be ideal to put along the length of a ridge on a house
nice one mate - great suggestion thanks for sharing
As usual U never cease 2 amaze me!!! Great now how BIG can we go with this design? I need some "More Watts"!!!
lol - as big as you can build mate - i may do a half meter version
I love this design, I am going to print a few and configure them as "fruit" hanging from a generator tree. I think I may use it to charge some batteries for a streetlight idea. One question, how long of a coil do I need to make?
Would love to see an array of these that you could "Add-On" for more power.
About 25 years ago my dad made an omni-directional turbine for pipes. It looks kind of like if the Predator designed a volleyball. Not sure what happened to it. He made his greatest success when he made a special structure that converts the energy of small waves into vertical height so that you can create a gravity feed of sea water into estuaries so that the estuary stays healthy and then the device managed to be used for the same functionality but to create a water turbine from constant waves. It's just a ramp but it has unique angles that amplify the wave into the right compression so that the wave can clear extra height. The Australian and German governments were going to build a lot of them but I guess then the pioneers of the WEF shut it down because it was too simple and effective. Just floating concrete ramps.
very cool story mate - thanks for sharing
If we are worried about flying animals going into the blades, have we tried putting a mesh over the front and seeing if there is a drop in power? Also how big can we go? Looks good to me. 👍
worth a try and see the result - cheers mate
I guess it would be somewhat important to make sure the magnets match up N/N and S/S on each side of the coil, as to not cancel each other out?
Magnetic fields are always between a north pole and a south pole - so the north poles on one side will link up to the south poles on the other and vice versa. That will cause them to move together, and also cause the magnetic field to pass straight through the coil as they rotate, which is what you want.
they line up automatically mate and the field needs to flow from N to S - which it will just do
Wonder how it would work if the stator is held horizontally?
yes it would
Great video. Question: What if the back of the 'fins' were open to the other side thus the wind would interact with the back fins?
they are - check out the drawing
Honestly thats a fairly genius design.i really enjoy that
awesome mate
Enjoying your channel and printing the parts now. What is the length and diameter of the serpentine coil?
I wonder how much more consistent wind power this design could generate, and also if it would generate more power!
It seems like the counter-rotating blades would be great atop a stack of your lateral wind harvesters (Darwin / Ventum), as that would maximize the efficiency of the blades while diminishing their potential harm against wildlife. But I can also visualize a large ball or omnidirectional "blade" above the same stack. I wonder if the omnidirectional blade catching wind from the side, but also being above a stack that is driving wind up, would have benefits? For one, it should operate in lower air speeds due to the stack concentrating air flow. A second benefit is it might also be more stable in higher winds (up to a point). But ... are there hidden problems to be discovered in the implementation?
Such an interesting result, a horizontal turbine that is a vertical turbine. Did like someone's suggestion to move the generator completely out of the wind flow. But there is another option, move the blades past the edge of the generator.
this is an example of generation at the rim mate if i moved the blades out i would move the generator out too
@@ThinkingandTinkering I was, like the other comment, thinking about the wind flow. In this instance trying to get some wind coupling where the blades had the largest leverage.
With the same size and design of the generator part, how does the energy production compare with conventional blades when going against a wide enough wind "surface" to hit the whole thing evenly? (perhaps you could test it by mounting them on the back of a pickup truck, one on each side to get the readings simultaneously symmetrically), and then drive back and forth a few times to get an average and cancel out the effects of crosswind on the conventional blades? Also, does this design produce the same amount of energy with wind coming from all directions, when the wind "surface" is large enough to hit the whole thing?
wind power is more to do with the area of wind captured not generator size
Robert, my friend went to India for a vacation. He told me the the people in that country are so wind crazy that you can see vertical wind machines as far as you eye can see spinning in the wind. This has to be one of the most important energy making machine PERIOD !!!! This is a very special unit to save a ton of money for energy used by anyone.
Well done fella. Peace vf
cheers mate
Keep up the great work fella. I know a many who use your knowledge to make free energy producing devices. Well done fella too. vf@@ThinkingandTinkering
Would you be willing to try using round neodymium magnets as external ball bearings on the outer rim of the wind turbine spinning inside of the coil?
My hypothesis is two fold. Firstly, that the magnets will polarly lock to each other and not roll unless under the correct amount of pressure and friction and then will roll as a tidy locked force. Alternatively spacing them out and allowing them to roll will both increase and interfere with the magnetic field cohesion within the coil. Perhaps ovals that could roll within thus accentuating the potential field motion dynamics. Perhaps being tunable to something akin to grouped vortexes as a sustained vortex wall to the larger field...
For stabilization of such a field, the inputs would have to be rotationally quantified to the coanda effect, perhaps a few strands of appropriately shaped electromagnets to be stimulated on the individual strand level.
Dear Robert, thank you for your next great video. For the next one, I recommend putting it in front of the measurement device big magnifying screen so the numbers measured are better readable
Thanks for the tip!
@@ThinkingandTinkering thank you for your great work
Execellent video very interesting you remind me of college lecturer i had in the past
This guy has always been amazing
Thank you for all your videos and your ideas. I love watching the videos. I am very interested in making a wind turbine that would generate enough power to run a heater ~ 5KW. Your ideas are great, but how would one go about scaling up the size to put the concept into practice, in an economical way. Thanks.
two ways basically - make them bigger or make more of them and link them up
@ThinkingandTinkering is there a tutorial on how to wrap the wires for the stator ?
You know that would work near the ground in high turbulence and low wind velocities. It would cost almost nothing to maintain. It may not have the highest theoretical efficiency, but I bet it can flat out generate any normal wind turbine for the same size over a year, and cost less.
Brilliant, thanks for sharing!
cheers mate
Great build. Have you considered combining The Darwin collector and having the air stream come in to the edge of a Tesla turbine. Air flow exits the center to capture all the energy with the stacked disks in the laminar flow?
That is brilliant my friend, truly impressive
cheers mate
Asked to scale what was the speed of that wind.? the hairdryer blows a lot more forcefully than regular wind naturally. This looks a little too bulky to produce naturally. We need a low speed turbine that can generate wind when it is not blowing. We also need a a solar panels that produces on the sun is covered with clouds.
This omnidirectional turbine did surprisingly well.
i thought that too! I was was a little surprised tbh
The two spiral blades wind capture does not work together like the 6 Blade in tandem configuration.
My understanding is when wind turbines are in high or I guess dangerously high winds they can generate too much energy and have catastrophic failures, I am wondering if regenerative braking technology like what is used in Ev's could be used to slow wind turbines as well as still collect energy all while keeping wind turbines from failing in conditions that can push a wind turbine into a critical state? maybe their are wind turbine companies already thinking about or implementing an idea like this if is possible or even viable.
