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 has become my favourite KZfaq 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 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

Recycle, reuse. Rob, you can obtain a motor from an LG or Fisher and Paykell direct drive washer which saves wiring your own. They are 3 phase and can be rewired in a variety of configurations and supply approximately 400W in a stiff breeze with the right turbine. The stator is laminated to reduce Eddy currents and the ceramic magnets can be replaced with neos for the best O/P.

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 😉

We would talk about a lot if we were in the same room. Nice work. Your close to describing what im workings with

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

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!

Fantastic video full of practical knowledge and information. Thank you Mr Smith.

Double magnet rotors at top and bottom of the bolts to double the magnetic field then generate more power , all the best .

This is amazing! I just found you today and I must, this is a perfect project for me here in windy Nova Scotia!

Brilliant video 👍 thank you 👍

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.

So this is how Anthony Hopkins powers Westworld!

Awesome build!

All of this, is of course terrific knowledge to have in the SHTF scenario where Society has failed and people must survive on their own.

I’m curious Rob. Out of all of the generators you’ve built how many are you using to power your home?

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.

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?"

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?

Good one!!!! I love these!!!

I'm amazed that made power wound that way.

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.

this was the video i was waiting for!

This is a super interesting build! I was curious as to its power output? like what voltage and current can be achieved?

Any way the wind blow, doesn't really matter.... I like how people walk by, smiling ...:) good one !

Dear Rob! Very, very good. How about staging up 3 generator parts in the tube? Cheers, Fred

A little empty plastic cup next to you as you stand at the supermarket with it spinning, probably make a few quid😅😅😅😅

Yes splat, finer wire but less amps ergo lower wattage.

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.

Brilliant: good on you Dude.

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.....😮😊😅😮😮😮

Would you consider going axial, with another set of magnets?

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.

Thank you for sharing your knowledge with us. Where do you buy the copper winding wire from?

Hi Robert and the rest of the youtube TNT channel, awesome channel, wicked demostration I do have one question that someone here might help out in a direction or 2 . well i have been slowly building the Mighty over the last couple of months when able as a wood model and would like to attach this to the archmedies screw in a river i have on the block with a flow rate 2-4 mps , My Question is how can i make the unit water tight so i can have the mighty enclosed with the archamedies ? please note i only have basic hand tools a few small power tools but 'pleanty of she be right' lets get it done. any help will be appreciated and welcomed. ⚡

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.

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?

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.

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.

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 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 😆

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.

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.

Does it have to be a close wound solenoid coil or could it be made from a basket weave coil having space between the windings ?

Have you thought about testing the output with another magnet rotor attached? To see if it's worth the extra magnets??? ✌️

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.

How many cycles was the last little 110v genny running at?

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.

Awesome!

to wire it in 3-phase w bridge rectifier and say a 50v capacitor ~ maybe to rows of coils offset, with to row of magnets. feasible? with an AC stepdown to dc 12v the first wooden on. wrapped individual bolts then wrapped on the outside would that nullify or increase volts.

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?

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

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.

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.

QUESTION: Would bigger magnets produce more watts?

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 ?

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.

Maybe I missed it, but does the thickness of the enamelled copper wire make a difference or any gauge will work?

A simple query, is it better to spin the coils, or the magnets? and why🤔

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 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.

I think practical voltages to try for are 5v or 6v for usb , and even a lithium battery.

Can you look at Micro Hydro?

This man and the guy who makes iron in clay kilns is kind of the same if time is ignored

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?

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

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.

Hi Robert... I plan to make the tiny version... But... Can you tell me - 1. Do the metal discs have to be steel, or will aluminium discs (which I already have) be as good? 2. Over time, will the mild steel bolts become magnetised and therefore compromise the efficiency of the generator? 3. Do you know the comparative efficiency, between a straight and a serpentine ungrinski turbine (as I do not yet have a 3d printer)? Many Thanks.

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.

So, how do you get lower voltage but higher amps out of a wind generator? Would it depend on wire diameter?

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.

Now if i want it to make 12vdc could you rectify it then put through a transformer for slightly better amperage? ?

I do not have 3D printer. Is there anywhere I can purchase already printed turbine blades like that?

Could you just leave the wire on the bobbin it comes on when you buy it and drill holes into that?

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.

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.

How come ?? did I missed some ? I thought the magnet moving in the same "direction" (linear) as the wire doesn't produce any electricity ?

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

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 CD's be used for the disks?

Didn't know they made plastic in 1796 :)

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 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'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 aluminium wire? is dielectric

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?

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.

can put flower turbine on top

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?

How many windings, 80 what?

I think it is the "Output from one into the Input from another?" or is it "The Input from one into the Output from the", Now I am confused! lol!

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.

Your clips are very interesting. Nice to follow and exchange fun and new knowledge. Hope you will increase our following as well. Thank you very much.

Sir how can I connect with you? Have sent an email but not sure if you received it.

can you make this 3d printed?

It's fall, this is a rerun. Where's the new SEASON? LOL

What if you just uses brass washers and a plastic spacer with a thin plastic insulator and wired the washers like a long wire as to make a maximum length. {-0-0-0-0-0-0-0-0-0- ?

Lol, has any one suggested just turning the great big spool into a generator?
