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.

@@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?

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.

@@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.

@@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.

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.

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.

However, it's got me wondering if I were to build a wind machine like you are showing .. but on a horizontal axis over the peak of the roof .. what it would achieve. I have shade trees that I do not want to cut down just for maximum solar .. but there is plenty of south facing roof for solar panels. I try to keep my mind open and really enjoy what you are doing with R&D in your space there. Truly amazing .. and we never know the extent of our influence. As regards to the capacitor .. 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's awesome to see you talking about extra coils sitting around the radius .. something I could see the possibility of .. even on both ends (top and bottom).

Hello, Robert. I have just this night come across your channel and video series. I'm in the States, so it's currently about 2:00 AM here but I can't tear myself away from your project. It is totally fascinating and I can't seem to tear myself away from it. I want to add my vote that you finish this series out to its logical end, regardless of the number of videos. I'm not familiar with the weather patterns there but here in the southern U.S., we generally have windy fall and winter weather and spring and summer tend to be less windy with considerable sunshine. I've been thinking for years now that the best method of self sufficient power here would be a combination of wind and solar. Your project has inspired me to start thinking again of building my own system. Keep up the great research. You're doing a wonderful job.

People died from freezing to death after Power lines were Downed across Quebec Canada. Many did not have power for over 5 weeks. We will face a CME or Major Solar Flare that will hit and take out large areas frying the Electric Grid.

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.

@KZfaq 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).

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

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

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!

When you connect all the transformers directly to each other you will need the coils to all be exactly in phase (very hard to do). By connecting them via a bridge rectifier and capacitor then it does not matter if they are in phase.

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?

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

@@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.

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 ?

Ya know Robert: with a long enough black pipe of reasonable diameter you could create the necessary draft required to turn that thing without actual wind.

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.

Hi Robert, I think it would be better to angle the corner baffles so they direct the airflow onto the driving side of the rotor and block the airflow onto the returning side, wherever the wind is coming from. Possibly curved baffles or more than four. Also would it help to let air out of the top and bottom discs to increase flow over the blades? Great videos, very thought provoking and well made

The number of coils can be a multiple of 3 as one configuration. Then connect every 3rd coil around the circumference together. So 24 coils will have 3 groups of 8 each. This should produce a 3 phase output, rectified by a 3 phase bridge if needed.

Impressive, my guess is that by adding the capacitors, they charge as the magnet goes passes the coil and then discharges through the recitfier to the load. As the caps are now discharged, they limit reverse current flowing back into the coils through the rectifier as the magnetic field collapses so a reverse/opposing magnestic field is limited. As you put it, it's like adding a clutch to a regenerative braking system but the tradeoff is losing that bit of power to the load. Look forward to the result, well done!

Part 5 ans 6 made me think, instead of having a complicated transmission system, maybe it would be possible yo use the coils themselves to control the speed by rotating the coils, of course out of the magnetic core, to change between horizontal and vertical position. In theory it would control the reactance, which each core being a gear up, but no need for s synchro, a clutch, lubirification or and anything a conventional gearbox need. Could be quite low energy to do so too as you only need to pivot the coil on itself. Very inspiring. Thank you for your videos, they are gold mines for ideas.

Nice addition - a jewel theif circuit seems the way to go. As wind speeds varies you can vary what coils are used. Soon you will be considering a generator controller to measure the RPM (pulses a second) to vary the load based on wind speed. Big wind turbines have an anemometer mounted on the rear of the turret so they can optimise how much energy they extract from the conditions at the time.
