I just made the experiment to compare single wire vs multi wire in generator coils.Aaron Murakami wrote:
If you do make 2 sets of 3 coils in series, when putting the output in parallel, probably have to go through diodes so they don't discharge into each other.
If your generator coils are charging a cap that you want to dump to a battery, I would dump it from that cap without further discharging into inductors, etc... you will have the least amount of loss that way.
I made 1 coil with single wire and 800 turns. 1 coil bifilar twisted and connected in series with 400 turns. 1 coil quadfilar twisted and connected in series with 200 turns.
I placed the three gen coils along with the motor coil. All coils out of phase. And started the machine.
All 3 gen coils gave me the same voltage. 7, 7 volts. Only with a difference of .2 volts between each other. One was 7, 5v, another was 7, 7 and the third 7, 9v.
I believe the difference is that probably I had some small difference in the air gap of coils.
So that's it. It didn't make any difference.
I got 7 volts instead of 5 volts. Because the rpm was higher. I was using 3 coils less than when I got 5 volts.
I will do what you Aaron told me to do. Connect 2 or 3 coils in series. Hope I don't get too much drag placing 3 coils facing the cores at the same time.
I have to say that the motor coil, which is a bifilar ssg circuit, is not tuned at all, in totally the opposite of been tunned, lol. Right now I don't have the tools to tune it, I am waiting for some hall sensors that I bought online to match the magnets, when I have all magnets matched I will tune it correctly. I just have 200 ohms in the base of the 2n2222, the trigger winding and the power winding have 12 ohms each (if my multimeter is correct). So I would probably will get more out of my gen coils when the ssg circuit is properly tunned. But I will put them in series anyway and work on the generator part while the hall sensors arrive.

i believe your not supposed to twist the wires with generator coils that tesla series wound.... you should try some without the twist -
#33 ·
This is a basic explanation of the Tesla Bifilar wiring method compared to normal:
That isn't discussing a generator coil but want to post that as reference.
This also isn't about generator coils, but when I used that wiring method for a Stan Meyer type circuit, I was able to get double voltage with the same input - this is an ancient picture I drew on the whiteboard that someone posted on their site:

This coming Monday the 10th at 6pm Pacific Time Zone, we're having a live Q & A call with Peter Lindemann and Aaron Murakami.
This is by invite only for those of you who have the Beginner's, Intermediate or Advanced Handbooks.
We'll be sending out the phone number and conference room ID on Sunday and Monday.
We'll be starting promptly and after the introduction and beginning announcements, we'll open up for questions.
Please review the books before the call - we only want to spend time answering questions about items that are not covered in the books.
This call could obviously go on for days but we will try to keep it to 1 to 1.5 hours at the most. We can also do other calls in the future.
Besides the books, here are some videos relating to the Bedini SG and even two on Battery Rejuvenation. After reviewing the books, these videos might answer a couple questions - in any case, they might get your own wheels spinning to stimulate some more questions!

so I just finished litzing the wire for my genny coil, it is almost 7 pounds of wire, 16 gauge x10 at 100 feet. don't put the drill on the ground without relieving the rotational tension.... it will spin the drill all over the floor and turn your nice litzed wire into a giant pretzel. luckily I have enough for another one
this is a serious piece of work.!!

lol, I had the same problem the other day. -

Yesterday I changed around my 6 gen coils, and put them in 3 groups of 2 in series, now I get 12 volts out of each pair, the 3 groups are out of phase.
I received a package of a laser tachometer that I bought on china (US$ 16), and did measurements of the rotor speed without gen coils, and with gen coils in place without connect, and I do lose some RPM with the gen coils in place.
It was 1950 RPM with no gen coils installed, and 1550 with the 6 gen coils in place. This little crap is going faster that I thought, probably because the small size isn't? The diameter of the rotor is 10 cm.
Today I will connect the output of the 3 pairs of gen coils to a cap, and then I have to dump it.
Can someone suggest an easy cap dump method? In the future I would buy one of the John B comparator cap dump circuits, but I have to find some other method for now. Any ideas? zener + transistor or SCR is viable? or not?. Or is better something with a 555, I have a 555 circuit that made when I was waiting for the rotor/magnets/magnet wire/etc. (But I would have to modify it since is 50% 50% duty cycle.
I have another question: can I mix in the same cap the radiant output of the ssg coil, with the output of the gen coils? or I have to use different caps and different dump cap for each?

Your RPM drop is 21%. The demo Peter showed dropped 0 RPM at the conference and before the book launch we reduced the gap by half and only lost 2%.AlvaroHN wrote:

You have a small build so makes sense that your wheel doesn't have enough flywheel momentum to keep itself up.
With 12v from gen coil, that isn't enough with a 12v battery. You need at least 2 volts above what the battery is at.
Can you post pics of your setup? -
#39 ·
Aaron my RPM drop is with no gen coils installed vs 6 gen coils installed. The RPM drop is just because of the iron cores. When I rectify the gen coils to a cap I didn't noticed any significant RPM drop.
In your demo ssg did you measure rpm without gen coil in place vs gen coil in place?
In the book says that core net drag is 0, which makes perfect sense to me. But I do loose RPM because of the core.
About the gen coils voltage: I get 12 v from each pair of gen coils but the input voltage is 5v. Yesterday I used a death battery as input standing at 9 volts under load, with that input voltage the RPM went up to 2200 and the gen coils would give 20 volts.
I'm attaching pics.

We can back the generator coil out far enough that there is no drag or ability to light the lights. The demo at the conference, we had brought the generator coil in close enough to actually light the lights, but still have 0 rpm loss. The demo in Peter's work room, the gap is 1/2 what it was at the conference and it lost 2% rpm but the lights were significantly brighter.AlvaroHN wrote:

The magnetic field falls off according to the inverse cube law (not inverse square) - just a side note.
Make sure you're rectifying the gen coil on the correct lead - it does make a difference whether you're getting the output on the punch up or punch down. -

Aaron the RPM measurements that I did was with the coils unconnected to anything. That is why I say that my RPM decrease is just because of the iron core alone.
I saw in the book video preview that you did loose 5 RPM when the leds where on.
But my question is. Les say you have 356 RPM with leds off. And 351 RPM with leds on. But what is your RPM with no gen coil in the frame? Is still 356? Or more?

Aaron and Peter congratulations on the 2 hours video of the live call, I couldn't make it and the video was very good for me, it was very interesting and also fun.
There is this subject that interested me the most, the lifepo batteries, since I was looking the other day for batteries for my little ssg with gen coils that I making (photos a couple of posts back).
The other day I got some lineal hall sensors so finally I was able to measure my magnets and match them!, now that I have them all matched, I am finally going to tune the SSG circuit, I haven't put an ammeter in the input yet because I didn't had an analog ammeter at the moment, but I bought 1 today, (I lost all my stuff from my olds SSGs).
The thing is that as my calculations I am going to need a very small battery for this. Because if a regular SSG power winding consumes 250 mA at 12V when the power winding is around 1 ohm, and since my power coil is around 12 ohms the amp draw is going to be 250mA/12 = 20 mA !!!. I hope/expect/wish that my calculations are correct, and I going to find out today.
So if my SSG circuit amp draw 20 mA, I would just need a 400mAh battery to run 20 hours.
And that became a problem, because smallest battery I could find was 12v 1ah sealed lead acid batt, which would run 20mA for days making my experimentation very long. And you said that gel cells are crap, sealed lead acid batt is the same as gel cell isn't???
But! on ebay there are these AA size LIFEPO4 batts rated at 3,2 volts 400 mAh, and four of those in series would make 12,8 volts 400mAh.. is perfect!
Is ok to use those batts? or they would explode?

At the conference, it has 0 rpm loss when the lights were on. The gap at that time was far enough away that there was no difference.
With the gap as it is now at 1/2 the gap, 2% loss in rpm with the lights on. If it is 356 with led's off with that gap, I'd estimate it might pick up another 5-10 rpm if the generator coil was completely removed.
I have some tests planned for that machine and I can measure that at that time by removing the generator coil completely. -

The gel cells actually do work out pretty good, but just don't have the long term life. All my early experiments going back 15 years were all gel cells.AlvaroHN wrote:

Yes, the sealed lead acids (SLA) are gel cells, but some are AGM (absorbed glass matt) and they're also a SLA. Gels and AGM are different but they're both sealed lead acids.
Yes, you can use those lifepo4's on a small build and they shouldn't explode.
This is what happens to lifepo4's in the worst case scenario - lots of vids on youtube of people testing them, shooting bullets through them, etc... they just smoke out but no flames and no explosions:
And that 250ma normal draw you quote is of course the expected draw before serious tuning. You'll be drawing less, but I bet you could get away with even less.
The demo model we show draws 1.3 amps for 7 transistors, which is only 186ma per transistor instead of 250ma - that is 25% less draw than is expected. I don't recall the resistance of the windings. -

Legacy of a World-Class Inventor & HumanitarianBedini SG. The finale to this paradigm-shattering trilogy teaches the reader how to convert the mechanical work produced on the wheel into even more electricity, in an extremely efficient way. As a matter of fact, it is so efficient that at the recent 2014 Energy Science & Technology Conference, Peter Lindemann was able to demonstrate how to light a large bank of LEDs to a very bright level without reflecting almost any mechanical load back to the machine.

Tnx for the reply Aaron, so probably I have the air gap to small, I am going remove (again) all gen coils, and play with just 1 of them changing the air gap, to compare generated voltage vs RPM drop to see at what distance is better for me. Then place all other gen coils at same distance.Aaron Murakami wrote:

Or maybe just let it like that, since the amp draw is proportional to speed, so I don't care if I am losing some rpm since the amp draw also goes down. -

For anyone experimenting with these lifepo4's, if you can pick them up cheap and they are well within your means, please experiment away... I picked up a couple (12V 10-14Ah $100 each) way back when they were first mentioned many many moons ago. I have not had better results with them than I have had with the FLAB's. I don't want anyone thinking this is "the answer" and spending $'s needlessly. If you are not attaining better than 1:1 with FLAB's, IMHO - these are not going to advance your research. These batteries behave VERY different than FLAB's one must re-educate and learn how they charge and discharge so as not to be fooled.
Example when fully charged, they rest about 13.25. when under C20 load they stay at 13.24 and do not drop 1/100V until the power is used. If someone has results to report that are different than my own, please do tell.
$'s are better spent on the wheel, the coils, and transistors. focus on getting a nice clean solid spike at 1:1 then add the generator/pickup coils, although, I have yet to see a demonstration from JB where he needed the pickup coils to get better than 1:1 In JB's recent DVD where he has 2 fans on the wheel and he introduces the comparator, he is getting well over 1:1 with no pickup coils using FLAB's.
Kind regards,

And again, just make sure the diode is on the correct lead on the gen coils because it does make a difference.AlvaroHN wrote:

Yes - the lifepo4's are not a magic answer and we left it out of the book partially because of the cost and we don't want to make claims that they have some rare advantage.
However, we know a handful of people that have been able to get better than expected results with them as mentioned a few times, but everyone has to do this at their own financial risk.
John likes to charge the lifepo4's with steady current using the current regulator circuits up to 14.8 volts and he doesn't really recommend charging them with spikes or caps, but we know some who do that have gotten them to stay charged up on these circuits.
Yeah, the discharge is a steady voltage plateau all the way across and then they suddenly drop off like a cliff - quite the opposite of lead acids.
