I don't know much about the bendini motor, so please tell me if I'm wrong and help me understand.
If the bendini motor can put out more power then it takes to run, then why cant you connect it to itself and have it run off it's own power and still charge something else?
Good question.I would refine it further : why not charging discharged battery while powering the circuit with the same one ? I bet a discharged battery even at 11V would have enough power to turn wheel ...
I think it can be done but amount of RE generated must be many times larger.

I spoke to my brother-in-law yesterday & he was describing his recently built Bendini motor to me. I could hear it running over the phone...
He is using a typical 9V battery (from a smoke detector) to run the Bendini, and it charges a 12V UPS battery.
I asked him the same question...why can't you take some of the output and feed it back into the input?
Wouldn't a couple of low-voltage drop diodes work for isolation and direction?
Hello guys, my first post in a while :)
The quick answer is no you can't charge the battery that is running the machine. Why ? because they simply don't like it.

I can see why you haven't posted for a while. You have nothing useful to say.
Hi All
Not sure if this would work but here goes :P Just thinking out loud in case I get hit by the bus of life tomorrow ;)
One thing I noticed a while back was that whenever I first connect the the SSG circuit I got a jump in voltage on the Charging battery before even starting the wheel.
I replaced the Charging battery with a run capacitor off a motor (40 MFD 370 VAC start cap) and if I just touch the negative terminal of the Primary battery to complete the SSG circuit I get 28 VDC in the cap.
Now if I start the wheel that 28 VDC will climb to several hundred Volts in a matter of seconds :o but will light the NE2 which is hard on the transistor :(
Here's the question I've been wondering:
What if you placed a switching circuit that connected completes the ciruit then disconnected the circuit completely and dumped the 28 VDC charge back to the battery, would it charge the battery or would it drain it because of the energy used to bring the cap to 28 VDC? It does seem to charge it faster than just connecting the battery to the cap because of the BEMF of the circuit somehow.
If that doesn't work would it be possible to increase the timing of this switching circuit and turn the wheel and discharge the cap fast enough not to hurt the transistor while back popping even more voltage to the battery and getting rid of the second battery from the circuit?
I tried this awhile back using a 555 circuit but it was tied to the main battery and blew the circuit because of the high voltage and slow timing and I haven't tried it since because I figured it probably be easier to do it of the wheel using a commutator and brushes, just haven't gone back to it yet.
Regards,
Paul
Not delving into Bendini much myself more on the thought of power cycling though (something i do think about :) ) Can i suggest a cross linked Compas relay to switch between batteries so one charges as the other discharges?!? it takes a bit of fiddlings but the theory behind it is if you wind a small coil and have a "floating" magnet it will align itself with the magnetic field... as your battery power drops so does your electro-magnets field then once it realigns to its natural state have a dual connection (both batteries) and the one with the best charge will have the strongest pull on the magnet and it will align with those connections... Cross the output connections with input connections and the batteries should rotate through as they discharge...
Just a thought and because this is no mainstream idea (they just use electronic switches instead, another possibility) But still an idea :)
Hi All
Well I decided to try something that I never tried before and although it took some messing around and tweaking on the POT but my Bedini wheel now seems to be running better than ever WITHOUT the charge battery in the circuit ;D Just a cap as in my last drawing but with a motor in parallel to the cap so that it acts as the switch to back pop the battery through the motor acting as a fast switch :o
Although my battery voltage went down from trying several different circuit configurations it's now been running for 30 minutes at better speeds than before and NOT stressing the transistor while maintaining the present battery voltage and running the little motor across the capacitor ;D
Guess I might have just found a solution to the fast switching solution ;D
I'll keep you all posted ;)

You are a prat, Pinestone. What Bourne says has been confirmed many times.
I wonder if it is because the driving coil is involved in a hot electricity application
whereas the pickup coil is about cold electricity.

I wonder if anyone has applied to a Bedini an automated two pole two throw switch (is this right?) to swap the batteries over,
on the fly, every ten minutes.
Paul.
Paul, there is a video posted on you tube that does what you are asking about except I do not know how long between the switch over, 10 minutes? I believe it was said to run for more then a week. I will try to find it and post a link to it for you.
Paul, the following link is to the video I was talking about. It is the last motor recorded in the video.

Hi All
Well the motor/cap combination in my last setup was interesting but it didn't keep the primary battery from slowly draining in my setup :(
@ Nightlife Thanks for the link to introvertebrate's video :)

I'm not trying to be rude, but "because the battery doesn't like it" is not much of a statement.
If it was an organic battery that had living cells, maybe I could understand his comment, but we are talking about chemicals, and they have no emotions.
If the Bendini outputs more energy than required to run it, then there should be some sort of switching/steering scheme that would allow for the use of one (or no) battery.
As I have said before, there are laws of physics and electronics that might prevent a device from running itself.
The answer is to build two identical units and use the output from one to run the other.
If you can get unit #1 to run unit #2 then it should be easy to get unit #2 to run unit #1.
What I'm saying is any device that puts out more energy then you put in must be able to run a duplicate of itself.
Even if it can't run itself, unless the excess energy is in another form, eg. heat.
I found it very interesting to hear about the use of caps with the Bedini motor. But, why not use super caps? (ultra caps) I have been playing with these lately and they do perform just like a battery, only better. I just read about a $169 flashlight designed for Police use that will run 6 hours and totally recharge in 90 seconds. Yes, it uses only super caps and NO batteries. I am also now playing with the Joule thief circuit and going to use super caps along with it. I have never read of any one using these with a Bedini motor although it may have been done already. Just my 1.5 cents.
Bill
Just to note another thing I did a while back and it worked well. Not a self run but
sure dropped the battery use to nothing.
On the output of the coil, run that back to a cap that is connected to the battery.
Between the battery and the cap, have two blocking diodes so that the output does
not try and charge the battery. This recirculates the unused power from the coil back
to the front of the circuit. Using super caps here may well help more.
thaelin
Bill, my design will be using super caps do to their ability to charge and discharge faster then a battery can. It should add more torque and be more efficient.

That's a great idea. I'll mention it to my brother-in-law & let you folks know how it comes out...
I like the switching idea.. I think it could work.
Jason
Please see my video # 3 on Youtube of my motor. It has 2 manual double pole-double throw switches on it for "changing" the batteries. Crude but effective. I'm going to research that switching circuit link referred to above. Maybe that'll get me a little closer. Keep up the search; I forsee a day when we are all powering our homes with some kind of pulse-type motor-generator. I suspect that there are a few brave souls out there that are already doing it!

I read somewhere that it can explode the battery if you run and charge same battery. :-\
Instead of using batteries, has anyone tried to use an a/c power supply that u plug into an outlet to the Bedini? Then have another one to plug back into the wall on the output side. Of course you would need to measure the input to output. Would this work or would those power supplies waste the additional power created? I am thinking of ways to try and stop the meter running, and not using a hammer lol

HI Mark if one build a multi coil bedini one can charge a bank of batteries which in turn can be plugged to AC wall by a grid inverter.
Grid inverters are a bit expensive. Although I heard that there are small one's about â,¬500.
Wish you luck with these motors.
Hi Gurji,
The power inverter I can get easily enough. Has someone built a multi coil bedini yet? If yes, I would really like to see plans so I can try and build myself one. I am a novice when it comes to electricity, so everything would need to be spelled out so I can understand it, as simple as possible with lots of pictures! :D How many batteries do you think it would need? That is the step I was trying to eliminate, the batteries.
Mark
HI Mark yes there are people here who build the multi coil if you browse the forum there are schematics too.
I am trying to build one myself and to use it's work force to turn an alternator but still in the process right now.
Ok get ready for work then. :)
Guruji,
Ohhh I like that idea! :o
If you have a link on the multi coil bedini, please post, otherwise ill have to get my lazy fingers to do some searching.
Mark
Hey guys
@ guruji & Mark69
For a multi coil setup go to page 31 of the document here http://www.panaceauniversity.org/John%20Bedini%20Technology.pdf
Lots of information, both informational and technical (schematics).

Paul
Thanks for the link Goat :D

I have built the solid state bedini charger. Now it usually outputs over 200VDC which is far too much for a 'normal' inverter (12 / 24 VDC input)
Wouldn't it be better to try to design something that could self-power and output 12VDC at enough amps to power an inverter?
This bedini motor runs itself without batteries
