This has become my favourite UA-cam channel!!! I love the simplicity with which you unlock what is otherwise a mystery to others. I've been tinkering with many concepts through the years, for the purpose of electrical generation. There is a wealth of concepts, knowledge, and attainable projects here. Thank you for making these videos, and please continue, you are making the world a better place!!!
I was considering making a DIY genny for a while. Mine will be scaled up a bit with bigger magnets, and I hope to use 10 AWG magnet wire. I have been trying to source some Iron (instead of steel) for the cores. I can't find anything mass-produced. I'm not a Smith, so I would need to use an angle grinder/die grinder and such...no lathe either/. I do finally have an entry-level 3d printer, so custom plastic parts are available. Your channels have been a great inspiration.
Great video Rob! I would love to see a collaborative project with you and Colin Furze! You both have an infectious laugh and a real curiosity for the world around you. I think between you, you could build something epic enough to break the internet. 😃
This gent definitely speaks my language and it's similar talking to my brother we often used to have these discussions , a great video and it's nice to be reminded of thoes basics principles of the early inventors? .Fabulous great viewing . MY BRAIN PROBABLY moves a little slower , but still so enjoyable 😉
I will have to make this generator. Starting with the wire. I can tell you I have found me a Tiny Tiger Ohlsson and Rice generator 300 watts of power with 1 H.P. 2 cycle engine. This was something I could not pass up Robert. Now I can see what the insides are of mate. Nice video and great work you do also Sir. Peace
Yet another great and interesting video! I put it to you that This IS Free Energy! You get something (for little outlay and no running cost) and the energy source would otherwise be just lost to nature! Even if a paltry 1% of people who have watched this (5K atm) ..... it would give you 50 people actively thinking of the concepts involved. Even if they never build one themselves those people will talk to others at some point in time and pass on the ideas, like a ripple in a pond. Who knows who you will affect in the future? Once again ....... Thanks!
Yea I do often think about how we overlook the little things that cumulatively could make a big impact. For example like I make coffee every morning, and that would be cool to ... i dont know have some kind of battery with an outlet that i could carry around the house, for making coffee, or when the kids use a blow dryer, or even some lamps. And with a few wind turbines charging a few of these kinds of battery packs i could have some in the house being used while others are getting charged, when the ones in the house deplete i flip them out etc. And if you multiplied that kindof behavior across the population that may be kindof significant, especially if you could scale up to where some of the larger batteries are charged by a little bigger turbines and stationary next to your washer and dryer machine, and multiply that across the population, and that might be some nice reduction in energy pulled from the grid. I suppose it's easy to quantify stuff like that 😂. He makes me want to build a couple of these and start playing. because of the geography of where i live there's plenty of wind. There's plenty of sun too but i kindof don't like the solar panel industry. I've heard just making one solar panel makes such a carbon footprint it takes years for that solar panel to make it back, and it could fail to work very well before it makes it back. But wind is solid. All ya need is grease and lube for the spinny parts. 😂
Great video, thank you. The first time I've seen your channel. Also a great idea to have a separate channel as an archive. Probably the most important development of technology for decades - the most important aspect of which is that it isn't being "owned" by some billionaire.
Greetings, Robert. On the metal disk model you tested at 17:00, as soon as you introduced another coil, I thought, "You madman. You utter genius!" And now I want to see what stacking another set of magnets on each end would do. The final question I have for this thread is, "Who put the floor so blinking far away?"
Love it. 👏👏👏 Your happiness is so infectious! Hey at 16:00 if you could keep sliding bits like that on the rod, would it generate more elctricity? Maybe it would get too heavy though requiring stronger winds? But if you were connecting it to one of those stationary recumbant bike excercise machines i bet you could charge up a battery pretty good with just some peddaling huh? Or no? I think it would be fun to charge batteries while excercising. 😂😂 Love your projects man!!
Ths super simple design is also infinitely scalable. Also, if one has access to a whole lot of the basic materials they can build them in either paea;;e; or in series qiute easily.
Does adding a second disc of magnetics on the opposite side of one winding make much difference in to optimize the generator? It seems it would be harder to turn… stronger field? and connecting each pair of magnets? which would now need something like a split drive shaft to exit power for the now entrapped coil… and inelegant brushes?
So long as the 2nd array of magnets are oriented the exact same, there should be a net increase in electrical potential output. However, if you do not get the magnetic fields lined up exactly, you begin to cancel out the magnetic field’s flux, and thereby adversely affecting the potential output. And yes, any increase in electrical potential produces an associated increased back EMF so it would necessarily increase the resistance to turning, but only under increased load.
Thank you for the video! Observation… Spools of wire (already wound) are purchased to wind smaller spools of wire. Can the purchased spool be used directly?
Could you share the length (or weight) of the wire you used in both kinds of windings (individual bolts or one winding around the whole thing). I'm curious if the efficiency is similar (voltage generated per length of wire assuming the same drill speed). My thought is that the single coil is less efficient because the south magnets are also putting field through the coil when the norths are on the bolts, whereas in the individually wound bolts, the south field goes outside of the coils.
2 questions; which is better, this coil or the serpentine? If you used thicker wire would it increase the amps, or more to the point could you skip a voltage regulator buy using the right coil?
So if you want more current over voltage, you'd need thicker gauge wire correct? What happens if you keep one of the mini mite's coils as the hair thin wire and the other as a heavier gauge? They'd probably not be in series, but I would think you'd be splitting the difference as far as how much of the input power you'd recover as V and I.
12:00 Loving the mad scientist success cackle! @TNT Omnibus Please use this generator to compare your version of the O-Wind turbine to these other turbines.
What is the relationship in volts and amp as the speed changes? When its slower, the volts dropped. Did the amps stay the same to equal the energy put in? Do volts and amps both drop with slower speeds? It would be interesting if the design set the amps and speed set the volts.
Hello, I have been building multiples prototypes of Darrieus wind turbine using 3d printer. Of all the generator s you have build, which one is the best performing, given the the performance of a 1-meter tall Darrieus turbine. Do you have quantitative data for your different generator design? Sorry for the bizarre English, I am French. Thank You for all of your work.
You’d want to transform first as transformers don’t work for DC. Of course if using for wind, it may be difficult to get a steady voltage because of wind speed variations, so it would probably be necessary to use a voltage regulator of sorts. I guess something like a buck booster or whatever it’s called may work somewhere in circuit. It’s very doable though obviously, as wind mill generators are a commercially available thing. You know, I’m with you and I think I’ll jump into doing just that…
banggood, ali express, covid got rid of all the good junk shops I used to get mine from. duck duck go is your friend, doesn't rat you out to the feds like google. Look he is winding nuclear control rods......
I'm just curious would washer on the magnets on side facing away from coils, would get great magnetic flux towards coils and therefore greater output. Just idea that follows your nut and bolts build. Very interesting build with readily available materials anywhere.
I would be curious to know how the Mighty Mite generator would work using a bifilar winding instead of a single wire? Another thought would be to glue the bolts to a cylinder that you then wind the wire around. Just a couple of thoughts. Would like to see both when you have time.
It makes a difference in that the thicker the wire is, the less length you’ll be able to shove into a given winding. So thinner gauge wire tends to give you a larger voltage potential. Of course ultimately less amperage could be handled by a thinner wire but as he’s already stated, high amperage will never be an issue with this design.
Rob love your video's have you ever thought about containing your coils in a stainless case and using liquid nitrogen to super cool coils to remove resistance , nitrogen is cheap and would not need much.
always. I'm working on a water wheel for my house main. Not like it costs me anything, water isn't going to care it has to push a generator on the way into the house.
Question - what if you took several of these MM generators and have them hooked up to a single turbine so the one set of blades turns all the generators at the same speed - and then combine all the outputs from the several MM generators?
Hi, Rob very nice video and good info I do not have a printer to build the blue turbine how much would it cost to have you make another one and sell it to me. and on the Thunderbolt why not try a coil on the other end too I would like to try and build one like the Thunderbolt to use on my waterwheel to run my home I would use a buck converter to a solar charge controller to an inverter please let me know on the turbine thanks.
Off hand, I would think that if you created another generator coil or two or more, you could place them inline on the same input shaft and connect the wires to link them in parallel. The output voltage would be reduced, but the current would be increased. Ultimately, the output will be the same power.
Hello, Can u please help me with the 1kw serpentine coil, what type of wire is required, number of magnets and size is required and what would be the RPM
can't make solar as in photovoltaic cells, but you can easily concentrate sunlight with mirrors and lenses. I actually wonder if you can combine the wind collector with a solar updraft tower.
Those designs are pretty awesome! I’ve been a fan since I heard about them. They tend to be very aesthetically appealing to boot. Like some big futuristic artsy…thing… Or some sort of weird memorial type “landmark” that just happens to power the hypothetical city near by or on the outskirts. I’m pretty sure I’ve even seen renderings or designs that also doubled as fresh water condensers or desalination plants or something like that.
Omg I Busted a Gut Laughing from hearing you laugh seeing the Energy Generation of a single Coil generator... so funny I would like to see if it's possible using gearing to up the RPMs by stepping up the Speed of the center rod. I'm referring to the Gears on a 10 speed Bike that has varied Gears that the Bike chain is repositioned to spin the Tires faster while We Pedal at a slower rate after we pedal the bike the tires spin easily when we first start to get going. After we get going pedalling faster to start, we then can reduce how fast we pedal by adjusting the Gear shifters controls until We get to Pedal Slowly but achieving More RPMs to Step up multiple Spins of the wheel Tire RPMs but pedalling slowly. 1:1 up to 4 wheel rotations to 1 Full Pedal rotation. If We set up the the same gearing setup and connecting the Gearing to the Center shift of the Generator - The Rotations being increased to take the wind power turning the Wind Turbine on its own that turns a tire chain that connects to step up gears on the center Generator Rod turning the Generator 4 x faster or whatever is ratio ends up being. Just thinking how to turn the center Generator Rod multiple times faster.
Hi Rob, can you explain the purpose of the heat shrink as I was originally thinking it was to insult and prevent the coil from being in contact with the bolt...however do the washers bridge between the coil and the bolt removing the insulation the heat shrink provides? What is the specification of the copper wire used? Another suggestion, most of the projects directly drive the generator, could you instead drive a large wheel with a belt to drive the generator, 1 turn of the large wheel would be several or many turns of the generator and hence a lot more output ?
The threads are sharp and the shrink wrap is to prevent the threads from cutting into the enameled surface of the magnet wire. It's not to insulate and protect the wire from being in contact with the bolt. The wire has an enamel coating that insulates it. If the wire didn't have an enamel coating, the wire coil would short circuit and instead of thousands of turns, it would be one.
I'm surprised you didn't leap on the serpentine arrangement with the copper weaving towards an inner ring of bolts. I like the carriage bolt improvement. I am curious to know if a shorter bolt would reduce the output significantly... What is the perfect bolt length? What if you did concentric rings at different voltages? I agree that wind is a necessary component of a diverse energy portfolio.
A shorter bolt does not have to equal less output. Keep in mind that it is about the length of the wire. If you put shorter bolts with larger OD washers that enable you to wind the same length of wire onto the shorter bolts, you would get the same output.
Shorter bolts with a fatter wind may actually be beneficial because more of the wire length would ultimately make and break contact with the magnetic field. There’s no way the bottoms of those tall coils are within the magnetic fields of those tiny magnets no matter how strong they may be…
@@revmsj That's not how it works. This set up uses to bolts to bend the magnetic field so that it is moving across the wire in a way that enables the generation of electricity. The magnetic field transfers into the bolts making the bolt temporarily transforming the bolt into a magnet. When the magnet moves away from the bolt and the next magnet which is set opposite (north south north south), it changes the direction of the magnetic field in the bolt. As a result, the coil is within the magnetic field of the bolt and that magnetic field is shifting from north to south thereby creating an alternating current. If the magnet's field was not transferring into the bolt, the device would not generate electricity because the copper wire would not be moving at a right angle through the magnetic field properly.
@@scotttovey I'm still very much a newbie with all this stuff, but was wondering based on what you wrote, would using a more highly magnetic bolt, like a more iron rich metal, work better than the stainless steel that is being used?
@@justinw1765 "would using a more highly magnetic bolt, like a more iron rich metal, work better than the stainless steel that is being used?" First, I don't think Robert would have used stainless steel. He would have went with the standard off the shelve bolts that are more ferrous than stainless steel. It is a good bet that using iron bolts or rods, will result in stronger current generation as a result of there being less resistance to the magnets magnetic flux. How much of an improvement can only be determined through experimenting.
That wire surrounding the entire set of steel bolts works because the magnetic field from the magnets puts a varying magnetic field into the bolts. Replacing the steel bolts with wooden dowel and it won’t work.
In your last iteration, could you instead of wrapping the wire around the outside, wrap inside the bolt and then the outside of the next bolt and vice versa to increase the length of the wire still?
Hey' rob I haven't give ya, no good idea's in a long time. SO, Here's a few : lay it on it's side, & put another " generator head" on the opposite 🤔 side 🤔. !!! OR : leave it straight up & down, and stack, blades & generator heads, one on the other and go as high as ya, like, that is my favorite idea " The second " one I mean... Go as high up as a light-pole......❤ or as long sideways as you're fence.....😮😊😅😮😮😮
First thing that came to me when I saw you test this in the wind is to put one generator at the top and one at the bottom of the blades. double the power using the same amount of wind
Unfortunately the power would just be split between the two. A certain amount of power is pushing the blades, that amount of power is then converted by the generator. There wouldn’t be double the power from nowhere y’know.
Is it possible to generate electricity using electro-magnets fired in a series? I have been wondering what kind of current could be induced by an electro magnetic device firing inside a coil or even several coils.
You can any amount of current out of the moving coil. It is only limited to the amount of force you put in, and the wire resistance. you were getting about 120Volts and even with 10mA it amounts to 120*.1=12W. Thats huge.
It’s not too difficult. He’s giving you the basics here. There are plenty of other channels and sites on line to give you step by steps if that’s what’s required. Just dig in and start dissecting, researching, learning, and tinkering, and before you know it you’ll have your very own basement installed nuclear fusion reactor producing clean and free energy for the rest of your life…😳
Mr. Rob, that "car alternator" normally weighs quite a bit, how did you just finger grip it and wobble it about effortlessly!? Like the alternator was made of plastic and aluminum!
I was expecting some kind of flea circus treadmill. Never dissapointed by TNT though. Was expecting to see blood during the lathe wind, if anyone tries that with re-used coated wire beware kinks and rough coatings or wear leather gloves. Wound some coils recently and trimmed all to same weight just as you suggested. Looks like a fascinating topology. Would clamp when drilling with such a large dia drill, incase it graps.
I have a question. If you create the small generator, as you have, with the small amount of offset in two halves to eliminate the “stall” if that is a satisfactory term, what if you repeat that on your disc in a larger diameter. Each successive winding would be just enough larger as to not interfere with the previous winding. The holes in the disc would appear in a sort of vortex so the each ring of holes had the necessary offset. More and more magnets would be required for each successive winding. I could imagine 30 rings on each side. That would continually increase the mass of the windings. If each ring required an inch for clearance then the total circumference would be around 60”. If you printed a vey large helical rotor it would take more wind and I would imagine and much larger bearings to eliminate drag. Once it got moving the mass of the windings would act as a flywheel. My concern is this. You mentioned that if the windings around your bolts In the first example had to be very uniform in weight to function properly. Would that also be true in my concentric ring model. If so the the inner rings would have to be thicker and then each successive ring would have to have the same mass as the first. Essentially getting thinner at each ring to maintain the same mass. I could foresee it being an expensive experiment but maybe it would produce more than milliamperes. Don’t forget that the input like wind or falling water is free.
I am thinking that this looks like a prime candidate for a windwall setup. one of these at the top and bottom of spindle axles going thru the vertical wind you want, going say 6 feet tall, 8 inches wide, times maybe 10, and another wall at 90 degrees if the wind is very irregular where you set it up, and carry up the leads of the generators to 16 or 12 gage electricians wire. take that over to your regulator set up and storage. I personally am looking at a mixed storage of hydrogen(via metal hydride flasks) and a standard battery bank system, so the battery levels out most of the flow, and the hydrogen goes to some burning engine for long down times.
Bro! That’s who he reminds me of! He looks just like Anthony Hopkins! That’s fucking awesome! I wonder if there are any DIY cannibalism-centric projects on this channel…🤔🤣
Dear Rob. Explain me this. A excavator works on hydrolic run on a oil pump pumping oil around. With this hydrolic we can create tons of power, (newton) if we convert this Newton to kw, regarding calculation the potental electrical output is more than the hydrolic imput. There are also electric hydrolic at the market, 12vDC 2Ampere with a outupt of 800N, this meens in theory the potential electrical output is bigger than the imput. Connect the hydrolic to a genarator and you might have more output thab input.
If you reduced the magnets by 1, or increased by 1, so that you have 15 or 17 magnets, you would reduce your cogging significantly. But would it produce electrical power as efficiently? I do imagine the low speed startup performance would be better.
You could combine your reversing screw and the geneva counter to make a winding machine. Or you attach a revolution detector to an arduino and have it turn the motor off after the desired number of turns are wound.
You could use a step down transformer say 2:1 primary : secondary. The voltage output of the trans former will half the voltage of the input and the out put current will be doubled. Remember power = voltage times current.
ahh mate - a few people will, indeed, tell you that. And i can understand that - talk is cheap - people say anything and everything - build one let me see - or are you saying I should 'have faith'?
Great job Robert, if the coil wire was twice as thick would you get half the volts and double the amps? Also have you tried the outer coil around the small coil arrangement to see if both generate? I think if the wire was put through a roller to flatten it you would have a bigger face area, maybe giving more amps? More would fit in the magnetic field too
OK.. so you say that winding a coil is not fun.. but in the back ground you have a spool of wire,, that is a coil. Would that work. or do you need the iron poles... if so.. could you drill holes in the plastic spool, and insert the pols, and just add the magnets to that. that would be a lot of wire.. the whole spool. just a thought.
I vote you take that big ass spool of wire behind you and shove a rod through the center, then repeat that with several new spools, then build a rotor w/ the biggest strongest magnets available! You may wind up opening some sort of inter-dimensional wormhole with that sucker!😳
I'm wondering about the steel bolt magnet armatures... surely residual magnetism would make them decreasingly effective pretty fast? I was taught (as a kid) that you had to soften the steel using a blowtorch flame, and that would make it far more effective. What I can nether remember nor even understand is whether it's better too let them cool slowly or quench the red hot bolts in oil. I can never understand the process of annealing vs softening... metallurgy, crystalline structure and all that... as a subject is worse than Chinese to me. Anyhow... am I on the right track? Would heating the bolts improve their performance in this situation or not?
What about using it as a secondary... Drive a load through the primary as you did and see if the voltage generated in the secondary increases as a result of the magnetic field of the primary.
I don’t get the “better than” thing with solar vs. wind. It’s like saying a car’s suspension is better than the headlights. They are both parts to a system.
I'm still baffled as to how that wiring works given the general magnetic field going through the bolt length, but the magnetic field must be looping around the outside of the stator? Regardless, wouldn't the individually-wound bolts approach provide even more performance than this simplified "around the bolts" wiring?
The winding method is, I suggest, a little dangerous! As for the generator, while anything is better than nothing, lack of laminated cores must waste considerable energy. We might light up this and that but really need to measure electrical energy out versus mechanical energy in.

Double magnet rotors at top and bottom of the bolts to double the magnetic field then generate more power , all the best .
19:50 what if you put on the shaft a drill head, or like the sun gears from a portable drill, to increase rpm. ?😅
Ths super simple design is also infinitely scalable.
Also, if one has access to a whole lot of the basic materials they can build them in either paea;;e; or in series qiute easily.
This is a super interesting build! I was curious as to its power output? like what voltage and current can be achieved?
Would you consider going axial, with another set of magnets?
Any way the wind blow, doesn't really matter.... I like how people walk by, smiling ...:) good one !
I’m curious Rob. Out of all of the generators you’ve built how many are you using to power your home?

Does adding a second disc of magnetics on the opposite side of one winding make much difference in to optimize the generator?

I'm just curious would washer on the magnets on side facing away from coils, would get great magnetic flux towards coils and therefore greater output. Just idea that follows your nut and bolts build. Very interesting build with readily available materials anywhere.
I do not have 3D printer. Is there anywhere I can purchase already printed turbine blades like that?
I would be curious to know how the Mighty Mite generator would work using a bifilar winding instead of a single wire? Another thought would be to glue the bolts to a cylinder that you then wind the wire around. Just a couple of thoughts. Would like to see both when you have time.
Maybe I missed it, but does the thickness of the enamelled copper wire make a difference or any gauge will work?
It makes a difference in that the thicker the wire is, the less length you’ll be able to shove into a given winding. So thinner gauge wire tends to give you a larger voltage potential. Of course ultimately less amperage could be handled by a thinner wire but as he’s already stated, high amperage will never be an issue with this design.
Yea it seems the length of the wire is how the equations are derived? That was my take away.
Rob love your video's have you ever thought about containing your coils in a stainless case and using liquid nitrogen to super cool coils to remove resistance , nitrogen is cheap and would not need much.
As a wind turbine how many revs must it go
I wonder if the extra build time is worth the extra effort compared to doing a serpentine oil with the flux magnets like he did in his newer video
always. I'm working on a water wheel for my house main. Not like it costs me anything, water isn't going to care it has to push a generator on the way into the house.
Question - what if you took several of these MM generators and have them hooked up to a single turbine so the one set of blades turns all the generators at the same speed - and then combine all the outputs from the several MM generators?
Could you just leave the wire on the bobbin it comes on when you buy it and drill holes into that?
How about comparing it using serpentine with no iron core?
Hi, Rob very nice video and good info I do not have a printer to build the blue turbine how much would it cost to have you make another one and sell it to me. and on the Thunderbolt why not try a coil on the other end too I would like to try and build one like the Thunderbolt to use on my waterwheel to run my home I would use a buck converter to a solar charge controller to an inverter please let me know on the turbine thanks.
Yes splat, finer wire but less amps ergo lower wattage.
Dear Rob! Very, very good. How about staging up 3 generator parts in the tube?
Cheers, Fred
So, how do you get lower voltage but higher amps out of a wind generator? Would it depend on wire diameter?
Off hand, I would think that if you created another generator coil or two or more, you could place them inline on the same input shaft and connect the wires to link them in parallel. The output voltage would be reduced, but the current would be increased. Ultimately, the output will be the same power.
Hello, Can u please help me with the 1kw serpentine coil, what type of wire is required, number of magnets and size is required and what would be the RPM
can't make solar as in photovoltaic cells, but you can easily concentrate sunlight with mirrors and lenses.
I actually wonder if you can combine the wind collector with a solar updraft tower.
Those designs are pretty awesome! I’ve been a fan since I heard about them. They tend to be very aesthetically appealing to boot. Like some big futuristic artsy…thing… Or some sort of weird memorial type “landmark” that just happens to power the hypothetical city near by or on the outskirts. I’m pretty sure I’ve even seen renderings or designs that also doubled as fresh water condensers or desalination plants or something like that.
Brilliant video 👍 thank you 👍
Omg I Busted a Gut Laughing from hearing you laugh seeing the Energy Generation of a single Coil generator... so funny
I would like to see if it's possible using gearing to up the RPMs by stepping up the Speed of the center rod.
I'm referring to the Gears on a 10 speed Bike that has varied Gears that the Bike chain is repositioned to spin the Tires faster while We Pedal at a slower rate after we pedal the bike the tires spin easily when we first start to get going.
After we get going pedalling faster to start, we then can reduce how fast we pedal by adjusting the Gear shifters controls until We get to Pedal Slowly but achieving More RPMs to Step up multiple Spins of the wheel Tire RPMs but pedalling slowly.
1:1 up to 4 wheel rotations to 1 Full Pedal rotation.
If We set up the the same gearing setup and connecting the Gearing to the Center shift of the Generator - The Rotations being increased to take the wind power turning the Wind Turbine on its own that turns a tire chain that connects to step up gears on the center Generator Rod turning the Generator 4 x faster or whatever is ratio ends up being.
Just thinking how to turn the center Generator Rod multiple times faster.
How come ?? did I missed some ? I thought the magnet moving in the same "direction" (linear) as the wire doesn't produce any electricity ?
Hi Rob, can you explain the purpose of the heat shrink as I was originally thinking it was to insult and prevent the coil from being in contact with the bolt...however do the washers bridge between the coil and the bolt removing the insulation the heat shrink provides? What is the specification of the copper wire used?
Another suggestion, most of the projects directly drive the generator, could you instead drive a large wheel with a belt to drive the generator, 1 turn of the large wheel would be several or many turns of the generator and hence a lot more output ?
The threads are sharp and the shrink wrap is to prevent the threads from cutting into the enameled surface of the magnet wire. It's not to insulate and protect the wire from being in contact with the bolt. The wire has an enamel coating that insulates it. If the wire didn't have an enamel coating, the wire coil would short circuit and instead of thousands of turns, it would be one.
I'm surprised you didn't leap on the serpentine arrangement with the copper weaving towards an inner ring of bolts. I like the carriage bolt improvement. I am curious to know if a shorter bolt would reduce the output significantly... What is the perfect bolt length? What if you did concentric rings at different voltages? I agree that wind is a necessary component of a diverse energy portfolio.
A shorter bolt does not have to equal less output.
Keep in mind that it is about the length of the wire.
If you put shorter bolts with larger OD washers that enable you to wind the same length of wire onto the shorter bolts, you would get the same output.
Shorter bolts with a fatter wind may actually be beneficial because more of the wire length would ultimately make and break contact with the magnetic field. There’s no way the bottoms of those tall coils are within the magnetic fields of those tiny magnets no matter how strong they may be…
@@revmsj
That's not how it works.
This set up uses to bolts to bend the magnetic field so that it is moving across the wire in a way that enables the generation of electricity.
The magnetic field transfers into the bolts making the bolt temporarily transforming the bolt into a magnet.
When the magnet moves away from the bolt and the next magnet which is set opposite (north south north south), it changes the direction of the magnetic field in the bolt.
As a result, the coil is within the magnetic field of the bolt and that magnetic field is shifting from north to south thereby creating an alternating current.
If the magnet's field was not transferring into the bolt, the device would not generate electricity because the copper wire would not be moving at a right angle through the magnetic field properly.
@@scotttovey I'm still very much a newbie with all this stuff, but was wondering based on what you wrote, would using a more highly magnetic bolt, like a more iron rich metal, work better than the stainless steel that is being used?
@@justinw1765
"would using a more highly magnetic bolt, like a more iron rich metal, work better than the stainless steel that is being used?"
First, I don't think Robert would have used stainless steel. He would have went with the standard off the shelve bolts that are more ferrous than stainless steel.
It is a good bet that using iron bolts or rods, will result in stronger current generation as a result of there being less resistance to the magnets magnetic flux.
How much of an improvement can only be determined through experimenting.
That wire surrounding the entire set of steel bolts works because the magnetic field from the magnets puts a varying magnetic field into the bolts. Replacing the steel bolts with wooden dowel and it won’t work.
In your last iteration, could you instead of wrapping the wire around the outside, wrap inside the bolt and then the outside of the next bolt and vice versa to increase the length of the wire still?
Hey' rob I haven't give ya, no good idea's in a long time. SO, Here's a few : lay it on it's side, & put another " generator head" on the opposite 🤔 side 🤔. !!!
OR : leave it straight up & down, and stack, blades & generator heads, one on the other and go as high as ya, like, that is my favorite idea
" The second " one I mean...
Go as high up as a light-pole......❤ or as long sideways as you're fence.....😮😊😅😮😮😮
Good one!!!! I love these!!!
Can you look at Micro Hydro?
Can i use that 125 volts generator to power my computer (if i make on a big scale 220 volts)
First thing that came to me when I saw you test this in the wind is to put one generator at the top and one at the bottom of the blades. double the power using the same amount of wind
Unfortunately the power would just be split between the two. A certain amount of power is pushing the blades, that amount of power is then converted by the generator. There wouldn’t be double the power from nowhere y’know.
Can CD's be used for the disks?
Is it possible to generate electricity using electro-magnets fired in a series? I have been wondering what kind of current could be induced by an electro magnetic device firing inside a coil or even several coils.
This is literally what a transformer is
You can any amount of current out of the moving coil. It is only limited to the amount of force you put in, and the wire resistance. you were getting about 120Volts and even with 10mA it amounts to 120*.1=12W. Thats huge.
I have collected over the years dozens of motors, generators, and magnets. I wish i could understand how to get them operating to produce power.
It’s not too difficult. He’s giving you the basics here. There are plenty of other channels and sites on line to give you step by steps if that’s what’s required. Just dig in and start dissecting, researching, learning, and tinkering, and before you know it you’ll have your very own basement installed nuclear fusion reactor producing clean and free energy for the rest of your life…😳
Mr. Rob, that "car alternator" normally weighs quite a bit, how did you just finger grip it and wobble it about effortlessly!? Like the alternator was made of plastic and aluminum!
I was expecting some kind of flea circus treadmill. Never dissapointed by TNT though. Was expecting to see blood during the lathe wind, if anyone tries that with re-used coated wire beware kinks and rough coatings or wear leather gloves. Wound some coils recently and trimmed all to same weight just as you suggested. Looks like a fascinating topology. Would clamp when drilling with such a large dia drill, incase it graps.
I have a question. If you create the small generator, as you have, with the small amount of offset in two halves to eliminate the “stall” if that is a satisfactory term, what if you repeat that on your disc in a larger diameter. Each successive winding would be just enough larger as to not interfere with the previous winding. The holes in the disc would appear in a sort of vortex so the each ring of holes had the necessary offset. More and more magnets would be required for each successive winding. I could imagine 30 rings on each side. That would continually increase the mass of the windings. If each ring required an inch for clearance then the total circumference would be around 60”. If you printed a vey large helical rotor it would take more wind and I would imagine and much larger bearings to eliminate drag. Once it got moving the mass of the windings would act as a flywheel. My concern is this. You mentioned that if the windings around your bolts In the first example had to be very uniform in weight to function properly. Would that also be true in my concentric ring model. If so the the inner rings would have to be thicker and then each successive ring would have to have the same mass as the first. Essentially getting thinner at each ring to maintain the same mass. I could foresee it being an expensive experiment but maybe it would produce more than milliamperes. Don’t forget that the input like wind or falling water is free.
A little empty plastic cup next to you as you stand at the supermarket with it spinning, probably make a few quid😅😅😅😅
what about aluminium wire? is dielectric
I am thinking that this looks like a prime candidate for a windwall setup. one of these at the top and bottom of spindle axles going thru the vertical wind you want, going say 6 feet tall, 8 inches wide, times maybe 10, and another wall at 90 degrees if the wind is very irregular where you set it up, and carry up the leads of the generators to 16 or 12 gage electricians wire. take that over to your regulator set up and storage. I personally am looking at a mixed storage of hydrogen(via metal hydride flasks) and a standard battery bank system, so the battery levels out most of the flow, and the hydrogen goes to some burning engine for long down times.
Sir how can I connect with you? Have sent an email but not sure if you received it.
Have you thought about testing the output with another magnet rotor attached? To see if it's worth the extra magnets??? ✌️
I honestly can't figure out why you have the entire bottom half of it (the part that you're usually holding onto). What's it's purpose?
24:53 If you double the wind speed of 3m/s, that half watt will turn into over 4 watts.
So this is how Anthony Hopkins powers Westworld!
lolol
Bro! That’s who he reminds me of! He looks just like Anthony Hopkins! That’s fucking awesome! I wonder if there are any DIY cannibalism-centric projects on this channel…🤔🤣
I think practical voltages to try for are 5v or 6v for usb , and even a lithium battery.
I wouldn’t be able to help myself, I’d convert the drill motor as per your earlier video and give myself an excuse to buy another drill 😆
Dear Rob.
Explain me this.
A excavator works on hydrolic run on a oil pump pumping oil around.
With this hydrolic we can create tons of power, (newton) if we convert this Newton to kw, regarding calculation the potental electrical output is more than the hydrolic imput.
There are also electric hydrolic at the market, 12vDC 2Ampere with a outupt of 800N, this meens in theory the potential electrical output is bigger than the imput.
Connect the hydrolic to a genarator and you might have more output thab input.
If you reduced the magnets by 1, or increased by 1, so that you have 15 or 17 magnets, you would reduce your cogging significantly. But would it produce electrical power as efficiently? I do imagine the low speed startup performance would be better.
You could combine your reversing screw and the geneva counter to make a winding machine. Or you attach a revolution detector to an arduino and have it turn the motor off after the desired number of turns are wound.
I'm amazed that made power wound that way.
You could use a step down transformer say 2:1 primary : secondary. The voltage output of the trans former will half the voltage of the input and the out put current will be doubled. Remember power = voltage times current.
Good,but look at Floyd 'sparky" sweets VTA and you CAN actually get more out than is put in!! Amazing!! 🤘🏻😲👍🏼
ahh mate - a few people will, indeed, tell you that. And i can understand that - talk is cheap - people say anything and everything - build one let me see - or are you saying I should 'have faith'?
@@ThinkingandTinkering So you do know.
can you make this 3d printed?
Great job Robert, if the coil wire was twice as thick would you get half the volts and double the amps? Also have you tried the outer coil around the small coil arrangement to see if both generate? I think if the wire was put through a roller to flatten it you would have a bigger face area, maybe giving more amps? More would fit in the magnetic field too
OK.. so you say that winding a coil is not fun.. but in the back ground you have a spool of wire,, that is a coil. Would that work. or do you need the iron poles... if so.. could you drill holes in the plastic spool, and insert the pols, and just add the magnets to that.
that would be a lot of wire.. the whole spool. just a thought.
Brilliant: good on you Dude.
I vote you take that big ass spool of wire behind you and shove a rod through the center, then repeat that with several new spools, then build a rotor w/ the biggest strongest magnets available!
You may wind up opening some sort of inter-dimensional wormhole with that sucker!😳
Thanks Robert
I'm wondering about the steel bolt magnet armatures... surely residual magnetism would make them decreasingly effective pretty fast?
I was taught (as a kid) that you had to soften the steel using a blowtorch flame, and that would make it far more effective.
What I can nether remember nor even understand is whether it's better too let them cool slowly or quench the red hot bolts in oil.
I can never understand the process of annealing vs softening... metallurgy, crystalline structure and all that... as a subject is worse than Chinese to me.
Anyhow... am I on the right track? Would heating the bolts improve their performance in this situation or not?
What about using it as a secondary... Drive a load through the primary as you did and see if the voltage generated in the secondary increases as a result of the magnetic field of the primary.
can put flower turbine on top
I don’t get the “better than” thing with solar vs. wind. It’s like saying a car’s suspension is better than the headlights. They are both parts to a system.
I'm still baffled as to how that wiring works given the general magnetic field going through the bolt length, but the magnetic field must be looping around the outside of the stator?
Regardless, wouldn't the individually-wound bolts approach provide even more performance than this simplified "around the bolts" wiring?
Over unity using the tesla schamatics with the use of the ground it self for the wires and the pulse generayed buy the energy around use
Awesome!
The winding method is, I suggest, a little dangerous! As for the generator, while anything is better than nothing, lack of laminated cores must waste considerable energy. We might light up this and that but really need to measure electrical energy out versus mechanical energy in.
