Robert you are getting to be the mack daddy of home engineering lately... Keep up the awesome work, your mind is never ceasing and that is what we all love about you... God bless be in peace God speed.
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.
Solid! Top KEK! You never cease to amaze. Your laugh when you are pleased with your results is priceless. Keep educating the masses. Knowledge is power, now you know and knowing is half the battle. The other half involves you doing something constructive with the knowledge. Now get experimenting and building something. Remember to share your knowledge with others, pass it on. Peace be with you.
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 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.
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!
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
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
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.
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.
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.
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 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.
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
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
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.
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.
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.🙂
@@andrewsmithmilan1780 Would it be possible to assemble the fins that were printed separately that could be locked together. I assume that this is the same way that they make jet engines, by assembling bits of fin together. This design could also be printed in sections to make a much larger version. What exact size were you thinking? What would be the optimum size for a cheap FDM printer do you think?
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
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.
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.
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 !
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.
FREND ! YOU ARE GENIAAAAAAL , WE HAVE SO MUCH WIND EN EAST COST OF AMERICA , and no one huragane can damage this turbine with so short blades , is a rose like , bravo bravo
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.
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
Great stuff Rob, as usual. These would be fantastic on the boundary fence and some other parts of domestic properties and the mirrored version gave a far more stable out put. Yet I would ask that you don't forget to implement the purposed experiment of housing the "rotating scythe", as you put it. Inside the Darwin housing, which would protect the rest of the world from those whirling blades.
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
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!
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.
Now that's a beautiful turbine! Thank you for this idea. Man-sized version would give some power 😅. Some strong fabric might work for bigger version. Also, how about adding a third propeller for the previous version. Would it start with even lower wind speed. Starting at 0,5 m/s wind would increase the annual spinning time considerably.
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.
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.
HEY ROBERT MURRAY-SMITH!!!! You could generate electricity by making this into a large inflatable kite. Make the whole thing out of shaped inflated mylar. If the blades are several inches thick of inflated formed mylar ballon, with a curved carbon fiber strut at the very edge of the blade and one at its base for each curved blade (6 on each side for a total of 12) plus one down the center (13 total carbon fiber struts) each thin and just to supply tensile strength. Maybe also a thin carbon fiber hoop strut going around the outside of the blades half way between the equator and the apex on both sides to provide a little extra support. If it’s filled with helium or maybe just air and the balloon is made out of black plastic so the sun heats up the air inside and makes it stay buoyant and float, then as soon as it gets high enough it will act like a kite and the wind will provide lift and make it spin and generate electricity. Maybe a combination for partial buoyancy at night. That way if a bird flies into it, it’s just hitting a soft balloon. Or, you could put multiple thin carbon fiber strut/hoops around it like a chain link fence or a net/grate so birds just bounce off. Stabilize it with 3 or four cables like at the base of a pyramid with a main cable in the middle so it won’t wander and you have a free source of energy! The higher it flies, the stronger the wind. Your neighbors might complain though. It would be great for people who live “Off The Grid” in remote locations.
I believe there could be issues with this. You'd need to transfer the energy back down, meaning a reasonably hefty cable, even a 12ga wire at say 20 meters is a substantial amount of weight. So it would need to generate quite a bit of lift. Further downwind, or rather upwind, in order to launch it would require strong winds or some other way of generating substantial lift from the get go. That said, in the aire of Robert, try it and let us know!
When you mentioned the counter rotating propellers after presenting the omnidirectional one at 2:47 my mind went 🤯🤯🤯 It's not only the concepts that you present that are amazing, the way the ideas are chained are a pleasure to watch! Thanks a lot for these!
Side benefit of that setup is one could probably go without the superglue coating trick, which can make quite a mess if not outright melt the part you're working on, been there done that destroyed some prints trying to glue them together ....
@@monadyne so far the various "infused" materials, from metal to carbon fiber to ceramic I've seen don't seem to do much more than wear out nozzles, if they have any significant improvements in durability I've not really noticed it.
@@robertsmith4681 Thank you for your reply. Hmm... one might think that the minuscule size of graphene molecules (as compared with metals, carbon fibers, etc.) might allow them to slip through the nozzles without much of an impact. Then again, my thoughts are unencumbered by any knowledge on the subject whatsoever.
@@monadyne The thing with graphene is that random molecules aren't going to do much if anything at all, you need this stuff to be sort of woven like carbon fiber for it to be a useful material, that's why it hasn't really been commercialized yet, making small bits of it is easy, long strands that can be woven into sheets and such, not so much,.
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.
Now we are talking ! That thing is awesome :) why not make one the same size as the razor blades for direct comparison? Aren't I helpful? Lol. Love it, can't wait to see more with it. ❤ I love the hub generation too, so compact. I wonder if one large one or the equivalent area in smaller ones would produce different results..
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
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
Nice, i need those to power wireless cctv. I need alternative source of power other than solar panel, it is often cloudy here in tropical climate area.
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!
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
Theonly real problem with wind power is how to make it centrallized so that the benefits feed only one major entity. The problem that complicates everything is how to monopolize and exploit centrally what should properly be owned and managed independently and diffusely.
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
I say the same thing about the 'laws of physics'....these 'laws' are simply our best GUESS at understanding what is going on. We really have no idea. And to suggest that these 'laws' are absolute is just plain ridiculous. We just haven't figured out how to 'break' them yet.
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.

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.
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.
That satisfied smile and laugh made me happy for you :) Good work!
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.

lol - nice one mate lol
I would like to see the performance of a much bigger version...perhaps something that matches the outside diameter of the bladed version
You'd need an industrial sized (very expensive) 3D printer for that. The normal bed size won't get much bigger, or Robert would do so.
@@andrewsmithmilan1780 Would it be possible to assemble the fins that were printed separately that could be locked together. I assume that this is the same way that they make jet engines, by assembling bits of fin together. This design could also be printed in sections to make a much larger version.
What exact size were you thinking?
What would be the optimum size for a cheap FDM printer do you think?
go for it build one and test
Love your enthusiasm for success, Rob. 👍👍👍
cheers mate
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
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
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.
Do you mean the American style or Euro style trucks?
interesting idea mate cheers
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 !
Similarities to the blade less hydro turbine; cool beans
cheers mate
Seems efficient compared to its size , well made , all the best . 🙏🏻
it seemed to do ok for sure - cheers mate
Brilliant, thanks for sharing!
cheers mate
Brilliant little video once again, keep them coming looking forward to the next omnidirectional ball video.👍👏
that is a thing of beauty.
cheers mate
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.
it may well do - 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
FREND ! YOU ARE GENIAAAAAAL , WE HAVE SO MUCH WIND EN EAST COST OF AMERICA , and no one huragane can damage this turbine with so short blades , is a rose like , bravo bravo
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.
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
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
Super in deed and a Momentous occasion !!
cheers mate
Great stuff Rob, as usual. These would be fantastic on the boundary fence and some other parts of domestic properties and the mirrored version gave a far more stable out put. Yet I would ask that you don't forget to implement the purposed experiment of housing the "rotating scythe", as you put it. Inside the Darwin housing, which would protect the rest of the world from those whirling blades.
calling it a rotating scythe was a joke really mate - i think the 'scythe' design in a Dawin is good too - but horses for courses!
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
Nice one Mate! Now you have a 3d printer can you explore the Lily prop?
I already did mate
I didn't know Anthony Hopkins was also a propulsion engineer with a channel on youtube.
This has been noticed before,,,However the subsctiber vanished,,,,,with *DELICIOUS* and a reference to Chianti .....😆
lol
and a few flava beans lol
Glad to see Bilbo Baggins got a job after the Lord of the Rings.
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!
Love your videos ✅
cheers mate
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
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
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.
Would have been interesting to measure the output power of that turbine. A good idea nonetheless.
cheers mate
Now that's a beautiful turbine! Thank you for this idea. Man-sized version would give some power 😅. Some strong fabric might work for bigger version. Also, how about adding a third propeller for the previous version. Would it start with even lower wind speed. Starting at 0,5 m/s wind would increase the annual spinning time considerably.
What kind of fabric? Mylar maybe?
i like that mate
Hi Robert, great design, would be handy as a comparison on the hill with the dual blade design at the same wind speed
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
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.
yes it would
HEY ROBERT MURRAY-SMITH!!!!
You could generate electricity by making this into a large inflatable kite.
Make the whole thing out of shaped inflated mylar. If the blades are several inches thick of inflated formed mylar ballon, with a curved carbon fiber strut at the very edge of the blade and one at its base for each curved blade (6 on each side for a total of 12) plus one down the center (13 total carbon fiber struts) each thin and just to supply tensile strength. Maybe also a thin carbon fiber hoop strut going around the outside of the blades half way between the equator and the apex on both sides to provide a little extra support. If it’s filled with helium or maybe just air and the balloon is made out of black plastic so the sun heats up the air inside and makes it stay buoyant and float, then as soon as it gets high enough it will act like a kite and the wind will provide lift and make it spin and generate electricity. Maybe a combination for partial buoyancy at night. That way if a bird flies into it, it’s just hitting a soft balloon. Or, you could put multiple thin carbon fiber strut/hoops around it like a chain link fence or a net/grate so birds just bounce off. Stabilize it with 3 or four cables like at the base of a pyramid with a main cable in the middle so it won’t wander and you have a free source of energy!
The higher it flies, the stronger the wind.
Your neighbors might complain though.
It would be great for people who live “Off The Grid” in remote locations.
I believe there could be issues with this. You'd need to transfer the energy back down, meaning a reasonably hefty cable, even a 12ga wire at say 20 meters is a substantial amount of weight. So it would need to generate quite a bit of lift. Further downwind, or rather upwind, in order to launch it would require strong winds or some other way of generating substantial lift from the get go. That said, in the aire of Robert, try it and let us know!
Execellent video very interesting you remind me of college lecturer i had in the past
That is brilliant my friend, truly impressive
cheers mate
When you mentioned the counter rotating propellers after presenting the omnidirectional one at 2:47 my mind went 🤯🤯🤯
It's not only the concepts that you present that are amazing, the way the ideas are chained are a pleasure to watch! Thanks a lot for these!
wow - cheers mate
brilliant design I want one
Now that's what I'm talking about!
awesome
Side benefit of that setup is one could probably go without the superglue coating trick, which can make quite a mess if not outright melt the part you're working on, been there done that destroyed some prints trying to glue them together ....
Would it be possible to introduce graphene into the material the 3D printers use, thus to strengthen the artifacts they produce?
@@monadyne so far the various "infused" materials, from metal to carbon fiber to ceramic I've seen don't seem to do much more than wear out nozzles, if they have any significant improvements in durability I've not really noticed it.
@@robertsmith4681 Thank you for your reply. Hmm... one might think that the minuscule size of graphene molecules (as compared with metals, carbon fibers, etc.) might allow them to slip through the nozzles without much of an impact. Then again, my thoughts are unencumbered by any knowledge on the subject whatsoever.
@@monadyne The thing with graphene is that random molecules aren't going to do much if anything at all, you need this stuff to be sort of woven like carbon fiber for it to be a useful material, that's why it hasn't really been commercialized yet, making small bits of it is easy, long strands that can be woven into sheets and such, not so much,.
superglue can be messy for sure!
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.
Now we are talking ! That thing is awesome :) why not make one the same size as the razor blades for direct comparison? Aren't I helpful? Lol. Love it, can't wait to see more with it. ❤ I love the hub generation too, so compact. I wonder if one large one or the equivalent area in smaller ones would produce different results..
Send wind upward with the darwin, and send wind downward with the darwin. Call it omni directional trans flux darwin wind generator
cheers mate
Mr Frank Wittle ... we will miss you!
indeed mate
This guy has always been amazing
Mr. Smith has the stuff that stuff is made of....the right stuff, that is....👍🙏
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
Honestly thats a fairly genius design.i really enjoy that
awesome mate
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!
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
Nice, i need those to power wireless cctv. I need alternative source of power other than solar panel, it is often cloudy here in tropical climate area.
i haven't quite finished with this but the design is open source so feel free to modify yourself
Would love to see an array of these that you could "Add-On" for more power.
It looks like the combined windmill/generator should work great in high winds. Can't imagine that it will turn in light winds.
Absolutely wonderful!
Thank you! Cheers!
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!
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
Theonly real problem with wind power is how to make it centrallized so that the benefits feed only one major entity.
The problem that complicates everything is how to monopolize and exploit centrally what should properly be owned and managed independently and diffusely.
This omnidirectional turbine did surprisingly well.
i thought that too! I was was a little surprised tbh
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
C-Rotor as Darrieus should be used with the NACA 0018 profile or even with the best profiles WUP 1615 or NACA 0018TC-39.
Angle of attack is 2.5..4.5
Elingate it like an american football. You'll maintain the asthetic and directionally, but increase the blade area.
nice
20 of these little balls would make a pretty cool roof panel....
yes they would!
YOU FLIPPIN LEGEND ROBERT. INSPIRE ME EVERYDAY.
lol - awesome mate - cheers
I say the same thing about the 'laws of physics'....these 'laws' are simply our best GUESS at understanding what is going on. We really have no idea. And to suggest that these 'laws' are absolute is just plain ridiculous. We just haven't figured out how to 'break' them yet.
absolutely mate
Yea, Looks real cool!!! I will give it a try!
This is Genius, so glad I found your channel.
Where are all the big guys doing this..?
cheers mate
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.
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
