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!
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
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!
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
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 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!
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.
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.
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.
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 😅
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.
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
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.
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.
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.
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.
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
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
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.
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 CZcams), 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
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.
@@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?
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!
@@ThinkingandTinkering Dude, this has potential in more then just Aero Dynamics.. You need to concider Hydrodynamics also... Smaller scale for small pumps and such too, or larger scale Etc... DUDE so many possibilities!!!
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.
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.🙂
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.
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.
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
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
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.
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.
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
Robert, just found your channel, my eyes now red raw from non-stop watching so many facinating experiments. How you find the time necessary defeats me! I have so many questions but the key ones: 1) Where do you source quality magnets and copper wire in the U.K. 2) I can cope with 3D prints 2.5 times the size of your Omnidirectional Wind Turbine, but I don't have the skills to draw it in CAD, is there any chance you could make the drawing available? 3) IfI were to scale up, I'm guessing that adding more rows of magnets and associated serpentine coils would increase power out - would this be correct and proprtional? 4) I was looking for a solution to heating my workshop over Winter, I tinker with soooo many things, Jack of all trades, Master of none, I was thinging of a sand battery, heated via solar panel, but now wondering if wind turbine(s), possibly charging / discharging 12v lead acid batteries as well as 'dumping' to sand would be suitable - what is your view on this? Phenomenal effort to produce these videos, hugely appreciated!!!
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.
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!
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..
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.
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?
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.

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
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
Genius robert
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
That is amazing 😀
wow - thank you
@@ThinkingandTinkering Dude, this has potential in more then just Aero Dynamics.. You need to concider Hydrodynamics also... Smaller scale for small pumps and such too, or larger scale Etc... DUDE so many possibilities!!!
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.
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, ADREED,!!
It should have read, "the most affordable tool," since that's how I tend the view of my own garden. @@AndreaDingbatt

Nothing to forgive, nor can I despite my desire. We've all been 'just here' at certain times and places. Magnets between the moments.@@AndreaDingbatt
lol - nice one mate lol
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.
Super fun!
It really is! lol
This is Genius, so glad I found your channel.
Where are all the big guys doing this..?
cheers mate
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
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
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
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
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
Yet again, you provide us more inspiration! Great work mate!
cheers mate
Now that's what I'm talking about!
awesome
That design would be ideal to put along the length of a ridge on a house
nice one mate - great suggestion thanks for sharing
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
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
Nice one Mate! Now you have a 3d printer can you explore the Lily prop?
I already did mate
What fun!
it was mate! - cheers
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
It looks like the combined windmill/generator should work great in high winds. Can't imagine that it will turn in light winds.
Robert, just found your channel, my eyes now red raw from non-stop watching so many facinating experiments. How you find the time necessary defeats me! I have so many questions but the key ones: 1) Where do you source quality magnets and copper wire in the U.K. 2) I can cope with 3D prints 2.5 times the size of your Omnidirectional Wind Turbine, but I don't have the skills to draw it in CAD, is there any chance you could make the drawing available? 3) IfI were to scale up, I'm guessing that adding more rows of magnets and associated serpentine coils would increase power out - would this be correct and proprtional? 4) I was looking for a solution to heating my workshop over Winter, I tinker with soooo many things, Jack of all trades, Master of none, I was thinging of a sand battery, heated via solar panel, but now wondering if wind turbine(s), possibly charging / discharging 12v lead acid batteries as well as 'dumping' to sand would be suitable - what is your view on this? Phenomenal effort to produce these videos, hugely appreciated!!!
Would have been interesting to measure the output power of that turbine. A good idea nonetheless.
cheers 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.
Mr. Smith has the stuff that stuff is made of....the right stuff, that is....👍🙏
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
This omnidirectional turbine did surprisingly well.
i thought that too! I was was a little surprised tbh
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!
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..
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
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?
