[@ThePwnageHobo]

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

[@oliverwilson11]

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

[@ulgencutube]

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.

[@doria567]

@@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.

[@user-cc7qg6rt7n]

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!

[@orpheuscreativeco9236]

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!

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.

it may well do - cheers mate

[@rudolfvanacker8569]

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.

[@ThinkingandTinkering]

it's 104mm in diameter mate if you grab the stl and upload them into tinkercad you will get all the measurements

[@guyvr3225]

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

[@dansmif]

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.

[@yvan2563]

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.

Glad to see Bilbo Baggins got a job after the Lord of the Rings.

[@russellzauner]

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.

[@christopherd.winnan8701]

Do you mean the American style or Euro style trucks?

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 !

[@makinganoise6028]

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.

[@user-jn4xr5yz7y]

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.

[@RyanJBarnard]

[@Luziferne]

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

[@christopherd.winnan8701]

A third set would be an interesting experiment, as would trying one of the new globe designs stuck out as a rear fin.

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

[@nonamenoname712]

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.

[@newolde1]

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!

(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

[@totherarf]

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!

[@totherarf]

@@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!

[@marklefebvre5758]

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.

[@silentferret1049]

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.

[@damaddog8065]

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.

[@theGreaterAwareness]

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.

[@ThinkingandTinkering]

very cool story mate - thanks for sharing

[@FinGoju]

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.

[@misterserious3522]

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.

[@liv7680]

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

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!

That is neat- interesting !

[@ThinkingandTinkering]

cheers mate

[@robertsmith4681]

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]

Would it be possible to introduce graphene into the material the 3D printers use, thus to strengthen the artifacts they produce?

[@robertsmith4681]

@@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.

[@monadyne]

@@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.

[@robertsmith4681]

@@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,.

[@ThinkingandTinkering]

superglue can be messy for sure!

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.

[@ThinkingandTinkering]

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!

Hello Robert, You might have seen this already, if not I suggest you look it up because I think you will find it very interesting...One of the world's largest tier-one auto parts suppliers claims it's created the "perfect motor." The compact Mahle motor uses no rare earth magnets, transmits power without contact or wear, and can run at high power indefinitely without overheating.

[@christopherd.winnan8701]

Do you have a suitable link?

[@ThinkingandTinkering]

the key they claim is a new cooling system mate

[@wiradharma7030]

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.

[@ThinkingandTinkering]

i haven't quite finished with this but the design is open source so feel free to modify yourself

[@mikaelfransson3658]

Thanks Rob. It look awesome!!! /Mikael PS. Bye the way, in the film 1984 (film from 1956) App. 4,20 minuts a Building have looks like a Darwin-Wind-Collector! And one thing more the half balls-wing are 3D:s and can we get the wind in a Darwin, get in a whirlpool configuration this Darwins can be our answer for the shortcoming of energi. And we can that! DS.

[@ThinkingandTinkering]

i will check it out mat - but v cool suggestions cheers

[@pauldent3059]

That design would be ideal to put along the length of a ridge on a house

[@ThinkingandTinkering]

nice one mate - great suggestion thanks for sharing

[@marcfruchtman9473]

This omnidirectional turbine did surprisingly well.

[@ThinkingandTinkering]

i thought that too! I was was a little surprised tbh
