[@hubrisnaut]

You solved my biggest concern! I was wondering how you were going to overcome inductive resistance. I was imaging some form of "engagement" relay at sufficient wind speed. This simple capacitor rectifier solution that works at low wind speeds is awesome! This brings many low energy capture devices into the realm of "doable". Congratulation Robert! I am really enjoying this series. Please continue it.

[@EnvenomatedNickels]

[@ThinkingandTinkering]

I was pondering it too mate especially as the coils and magnets were almost certainly out of phase and it was going to be one hell of a job to get them in phase lol

[@hubrisnaut]

@@ThinkingandTinkering Would you explain how you hooked up the components in a video, or share a schematic somehow.? In comments back and forth with other viewers here, some of us are not 100% sure how you did it. I assume you hooked up the coil, capacitor, and ac input of the rectifier in parallel (I also assume this creates a 'frequency resonant circuit'). I am really curious about the science of what is going on in the circuit. Is DC output self limiting? Meaning, would it only output a certain amount of DC current based on the resonance of the circuit itself? As DC current is drawn off does the inductive resistance between the magnets and coil increase?

[@jsoswell]

Thank you!!! Based on your discussions, I have been playing with a shake flashlight run off a coil and a magnet, and a tesla coil. I was able to remove the magnet, and charge the capacitor right from the field coming off the tesla coil, then inducing an electric current in the coil of the shake light. Like I said before, you are my best friend as it relates to this area of thought. I had to leave my job due to policy changes that I wasn't happy about, and this is giving me more entertainment than I've had in years. Keep it up!!

[@ThinkingandTinkering]

that is an awesome thing to do mate - I popped over to your channel in the hope of seeing a video on that - fancy doing one?

[@jsoswell]

@@ThinkingandTinkering I may have to give that some thought. I should have most gear to make it possible. I might be able to recruit my brother. You’re inspiring me, my friend. Who knows what will happen?

[@jsoswell]

So, my Tesla coil has an audio input which allows me to hook up an audio source. The plasma heats the air to produce the sound waves. I want to hook it up to a test tube of water, and a tone generator I built with my brother, and see what different frequencies of plasma would do to the water. Could I generate Brown's gas, and would the right frequency give me a better conversion rate? Heck, if the anode and cathode could be separated, could one get pure O2 and H2? Which could be burnt none the less to produce pure distilled water. Desalination maybe? Hmmm.

[@ThinkingandTinkering]

@@jsoswell it would be awesome if you did mate

[@jsoswell]

Then my question would be, would your wind turbine be able to power the Tesla coil to produce flammable gas from salt water, which would be burnt for energy, water, and sea salt production?

[@paulrichards1061]

I would recommend rectifying each coil and paralleling the rectified outputs together. This full wave rectified output can then be fed into a charge controller that has mppt (maximum power point tracking) costing around £30 (easily found online) . The mppt charging controller will always ensure there is no load at startup and always ensure the maximum power point is achieved on load.

[@ffaubert1]

Would it be possible to see a schematic for those of us a little less technically inclined Paul?

[@ffaubert1]

@RealFamilyMan Thanks!

[@ThinkingandTinkering]

cheers mate - I will have a look for one

[@gabigabby3302]

@@realfamilyman The main problem to overcome is to have all the coils output in phase. Otherwise it will happen as Robert explained when he connected the coils directly. If the outputs are out of phase they will cancel each other and this will increase the resistive magnetic field. In a factory generator all the coils are perfectly aligned in order to be in phase and the output to be able to be added.

[@hubrisnaut]

@@realfamilyman What page? I am curious to see the schematic of Robert's circuit. I think the issue is if you went with a single rectifier, the coils would have to be perfectly aligned so there was no out of phase sine wave cancelling effect. There would be losses there if not. Who knows how much? What is also nice about this approach is it is a simple modular design most shade tree tinkerers can do.

[@martinbroughton6655]

Each coil is an AC generator and the number of magnets passing over the coils, along with your RPM will determine your frequency. To be able to have these all work in unison would require precision placement of the magnets and the coils. It is of course do able but what you discovered and I love that eureka moment is converting each untimed AC wave to a common DC. The real credit goes to the diodes in the bridge rectifier. The capacitor depending where it was (ac or dc side) would mainly contribute to the smoothing out of any ripple. (Or unwanted back EMF if in parallel on the ac side) I couldn't quite see its position but my guess it was on the DC side. What happened in the beginning is the AC waves from one coil was creating a badly timed opposing magnetic force in another coil hence the brake effect. Well done again because although it was not what you desired you had also created dynamic braking. Now by the time you get to about your 70th video you could use that principle to avoid over revving your generator in high winds !! Keep up this great stuff we love it.

People died from freezing to death after Power lines were Downed across Quebec Canada. Many did not have power for over 5 weeks.

Love your vids Rob. A bridge rectifier funnels the AC into DC and the capasitors act as a smoothing of the drop out from the diodes.

[@PurpleProAudio]

I've read that you should have the coils offset from the positions of the magnets to avoid 'cogging' (so using 13 coils with 12 magnets for example) The relative positions of your coils with respect to the north/south outputs of your magnet array may be what also contributed to the rotor stall? Also using a three phase system with a three phase bridge rectifier may help to smooth out the torque load on the rotor as this will even out the transfer of power. Three phase output also has the advantage that when rectified produces a smoother DC level with less capacitor size required. obviously DC output is significantly more dangerous than AC so the gloves are a great idea! I really love your videos and I especially like the way you include the learning process which I think makes them very inclusive and inspirational for prospective builders. Thanks for all the inspiration!

[@bobkelly2447]

Absolutely Brilliant ! ( i finally found this video again!) the capacitors decupling the load is fantastic.... this is the problem I have had for years that I could not figure out (wiring a bridge rectifier directly to the coils and to a 12v light virtually killed the spin ! it seems to me that the decupling effect would depend on the amount of capacitance that is used... but I am not sure... ....time to dig out the old project it seems THANK YOU !

I could imagine that the capacitor would take the "load" off the magnetic energy collected in the coil pass .. kinda like a check valve.

It may have simply been the case that you had the coils out of phase when you had them hooked together. When you were positioning them to hook them into series or parallel, did you look at their outputs on a multi-channel oscilloscope to confirm that they were in phase?

[@ffaubert1]

Unfortunately, I imagine quite a few of us don't have thousands or even hundreds of dollars of electronic test equipment at our disposal. Is there an easier method to discover this?

[@AtlasReburdened]

@@ffaubert1 Fair point, let me give that some thought.

[@DonGeatschos]

You dont need a multi channel oscilloscope for that. Simply hook up two coils in series and measure the ac voltage using a multimeter. then adjust the position of the coils until you get maximum ac voltage. Of course this only works if the magnets on the underside are spaced evenly. Or in Sir Roberts case are not spaced at all :D

[@AtlasReburdened]

@@ffaubert1 As Gerald stated you could roughly line up the phases by connecting the coils in series and using a multimeter, adjust one coil until you have the highest AC voltage, or if you want to be fiddly and unnecessarily precise like me, you could build a simple circuit to align the phases based on their 0 point crossing time. You would need a dual op-amp chip, two resistors, and two LEDs, and a 5V supply. You would connect the negative inputs of the op-amps and the same leg of each coil all together, then each of the other legs of the coil to one of the op-amp's positive inputs, one resistor(100-200ohms would do) to each output of the op-amp, then both LEDs between the unused ends of the resistors with one facing one way and the other reversed. Naturally the 5V supply would have its positive go to both the op-amp's VCC and it's negative would go to the op-amp's ground. Then when the magnets pass the coils, any discrepancy in phase will illuminate the LEDs, with the severity of the discrepancy reflecting in how long they stay lit, and perfect matching of phases would result in the LEDs not illuminating at all.

[@MrTubeuser12]

so if the coils are put "in phase" then would the capacitors not be necessary ? if you keep the cap./diode bridge for dc output with the coils in phase, then would the caps. affect how the coils are coupled/decoupled from the magnets ?

[@BeowulfNode]

If the wiring diagram of the options he tried is what I think they were, I think it's the full bridge rectifiers on each coil that is making it run properly. The capacitors are also hugely beneficial for providing useful DC, instead of highly fluctuating voltage. The reason I think it's the full bridge rectifiers making things work when combining the outputs of multiple coils to a single load, is that they are the preventing current being forced back through one of the other coils. Without the full bridge rectifiers, the slightly irregular spacing and placement of magnets and coils cause slightly differently timed peaks in voltage, causing the current to be driven through the other coils, and the driven coils to act as brakes. This does not matter if the coils were wired in series or parallel. Using a full bridge rectifier on each coil lets you combine the DC output sides without letting current from one coil affect any of the others, and using capacitors across the DC sides smooths the output voltage.

That's a great project and it's amazing it would be nice if you can make a video on how to store that energy you make great videos keep it up

[@shaundelear]

Brilliant really well explained -thanks you could use the top disc maybe an ink hybrid?

[@ThinkingandTinkering]

I like that mate - cheers

[@cvalliance6442]

I think this fascinating. It would be great to go over BASIC ELECTRIC CIRCUITS FOR THOSE of us that failed that in Engineering but were saved by the bell curve

[@NorthernKitty]

Your videos in this series are a lot like chocolates - there can never be "too many". 😋

[@ThinkingandTinkering]

lol - so true

[@mmmcquoid]

I am a recently retired electronic eng ,the capacitor will smooth out the hills and valleys in your dc voltage the bridge just flip flops and gives you positive feed .witch in turn smooths out the dc ripple allowing the rotor to run smoother and less obtrusive. Now you puy your magnets to the outside so you going to get higher voltage lower current. If you were to put the magnets in half way you could use the the coil and raise your current. remember if you add a heavy load 4 is enough or it will stop turning.have a nice day

[@dewagter]

Hi, very nice work. About the diodes: they only allow current if the voltage is larger than the diode forward voltage of about 0.3 to 0.6 volt. So while the spinning is still very slow, the coils probably don't make enough volt to allow any current, meaning there is no force yet. Nice idea to use this as a clutch. The only downside is that you loose a bit of energy. Note that with the diodes it makes a big difference if you use the 2V or 20V coils. With the 20V coil the diodes should engage at much lower rpm, but the energy loss will be much less. Thanks for your videos.

Great progress! It seems that building a wind turbine is almost as effective at stopping wind as building a kite!

[@ThinkingandTinkering]

lol - cheers mate

[@SprocketN]

I agree with the comments below, keep this project going to its conclusion. I’m looking forward to seeing it on the roof. I’m not generally keen on windy days, but let’s have a few so this can be tried ‘in the wild’.

[@ThinkingandTinkering]

we are due a bit of wind Friday I think

[@johnmoore6501]

I was worried that you would lock up the turbine magnetically with too many generators. But I never ever thought of using capacitors. Very clever. 👏

[@ThinkingandTinkering]

cheers mate

[@frankstocker5475]

You can also put magnets & coils on the top ring this will double the output.

[@ThinkingandTinkering]

for sure mate

[@jameswaters4066]

That's a nice rectifying and smoothing circuit for the AC coming from that turbine. Especially running a DC circuit like LEDs. More efficient use of the power.

[@ThinkingandTinkering]

Thank you very much!

[@tj48649]

Thank you! Great video and very interesting. I'm so glad you made it!

[@CrazeUK]

You remind me of Anthony Hopkins, aka Hanibal Lectre. Fantastic video, once I've moved I mat try to look at building a number of these

[@michaelschauperl172]

Thanks for sharing these videos. Keep up the great work!

[@ThinkingandTinkering]

cheers mate

[@wayne1959]

love your work so far mate..the more the merrier as far as videos go i reckon.

[@Kiyarose3999]

Fantastic, it just keeps getting better! 🌎✊🏽🌻✌🏽

[@ThinkingandTinkering]

cheers mate

[@brettjamesy]

Its my understanding that the problem you experienced prior to using the bridge rectifier/capacitor, could be related to multiple coils (4 in your case) being connected together and out of phase. The net result would be each coil presenting a load to all the other coils. By including a bridge rectifier you have effectively isolated each coil from the other, so no opposing reaction is present

[@herenow2895]

I watched a video about turning an alternator into a PM generator. They added a bridge rectifier. I just assumed it was the usual format for this sort of project. This is a great build Rob. Do as many videos as you see fit. I for one am hungry for the inspiration and progress updates.

[@ThinkingandTinkering]

cheers mate and thanks for taking the time to post

[@McRootbeer]

I think RMS's wind turbine wonders is the best show running on KZbin. I hope it gets picked up for a second season. Or at least has a special episode where an electrostatic motor gets connected to the turbine.

[@MrTubeuser12]

stay tuned, "same BAT time", "same BAT channel". LOL

[@ThinkingandTinkering]

lol - cheers mate

[@energycrafts8206]

Robert, The capacitor effect on the rotor torque you found is one of the secrets me and a few others had discovered many years ago in doing free energy research. Using this principe in fe devices made a big improvement in input/output efficiency. At first I thought the improvement was due to simple cap smoothing of the rectified ac source. Further tests proved conclusively that smoothing was not the answer and something more special was going on and not described in any literature I could find. Point 2. To find the ideal number of generator coils and amount of load for a given wind speed do this. The ideal load only occurs when the impedance of a load and the generator coils are equal. Electrically, this means when the open circuit voltage of the generator is lowered by 1/2 with a resistive load attached, then that resistance value is the equivalent ideal load impedence for max output for a given wind velocity. Since you experienced no reduction in rotor rpm, it seems you are way under utilizing the coils and the amount of loading the rotor at 10 rpm is capable of. ie. More coils and or heavier loading. Great build.

[@ThinkingandTinkering]

that is interesting mate - thank you for taking the time to post

[@pulesjet]

For optimum power insure all coils are in phase with each other. Most all PMA (permanent magnet alternators ) use 120 degree phase separation and rectify each phase on it's own. Altinertly you could rectify each coil output and combine the DC power as a whole.

[@ThinkingandTinkering]

cheers mate

[@bditty7393]

I would hazard a guess that the 4 coils are out of phase so when wired together they act on each other like a EM brake. by rectifying to DC it removes all potential for any phase miss match.

[@aion2177]

aha this is the only answer which actually makes sense in my mind :)

[@ThinkingandTinkering]

I think so mate - cheers

[@ZsOtherBrother]

@KZbin Censors Opinions Nice thought, I believe you're partially correct: If the coils are out of phase, and not exactly 180°, then the rectified voltage will also be out of phase, and there would still be a voltage difference in the different coils, but smaller... which would decrease inductive resistance, or even eliminate it, (if the phase difference was originally 180°). However, since the capacitor "smooths out" the wave form, removing it may increase those temporary voltage differences, leaving you with a "partial proof". As a side note: adding a capacitor to a coil may reduce energy losses, (if the capacitor is the right size to achieve resonance, or close to it).

[@FladFlidington]

One of the big problems with this type of wind turbine is overspeed in high winds, de coupling some or all of the transformers from the cap's and rectifiers when a preset voltage is reached would in fact provide a safety breaking or governor system that could automatically control the higher output voltage and also the integrity of the structure. I live in an area where wind speeds occasionally exceed 90 kph, we are not too far away from a wind farm. Keep up the excellent Projects, Thanks'
