Back in 2007 I filmed a little demonstration — a completely self-running, closed-loop Bedini SG oscillator built around a trifilar coil. No batteries in the loop… just capacitors that keep charging themselves indefinitely while the system runs at a voltage far below what the transistor is “supposed” to need.
Watch the newly re-uploaded video here (details below the video):
What you’re seeing:
Classic trifilar Bedini SG coil (23-gauge, ~2,000 turns): power, trigger, and one completely isolated recovery winding
RCA 3055 transistor (yes, the old-school one)
Front-end powered only by capacitors that are being conditioned with a high-frequency, high-voltage relay/ignition-coil pulse circuit
Recovery energy from the isolated winding is fed straight back to the input capacitors — the input side literally cannot “see” the output side – if it did, it would wind down fast and defeat itself
A simple ground rod connected to the circuit (just like John Bedini showed on the original 1990s KeelyNet schematics)
The result? The input capacitor drops a little at start-up, then climbs back up and just… stays there. I left it running for a long time until I literally got bored. The system stabilizes and oscillates forever on its own recovered energy — and it does it while running on less than a volt, way under the official transistor spec. That alone tells you something very non-conventional is happening with the current.
John Bedini always insisted the earth ground made the machine “run stronger.” Most builders ignored that detail. This demo proves he was right — you can see the dramatic difference the moment the ground rod is connected.
Those old original schematics that John originally posted are down below.
Why this matters in 2025
Two weeks ago I wrote about the Benitez self-running systems from the early 1900s. After personally witnessing multiple closed-loop devices over the years — including this simple oscillator — I’m no longer surprised that Benitez may have been telling the truth. In fact, when you study his patents side-by-side with some of the later “free energy” circuits that became famous, the family resemblance is unmistakable.
The real magic isn’t in complicated hardware. It’s in understanding switching, energy recovery, conditioning (caps or batteries), and the role of the local environment (yes, including that ground rod most people leave out).

Carlos F. Benitez, a Mexican civil engineer from Guadalajara, filed a series of patents in the 1910s that described self-sustaining electrical systems capable of running motors and lights indefinitely while recharging their own batteries—and producing surplus energy. A century later, these ideas remain controversial, but they’ve influenced modern free-energy work, especially John Bedini’s SG (School Girl) systems. Whether Bedini knew about Benitez early on or not, the principles are essentially identical: discharge one battery to pulse another with radiant spikes, yielding more than what left the input. In this post, I’ll break down Benitez’s patents, compare them to Bedini SG, and explain why low-impedance batteries can make results easier to achieve. I’ve spent years digging into this, from witnessing Paul Babcock’s shop demos to running my own Bedini setups.
The Bedini SG is a simple circuit: a battery charges a coil, the switch turns off, and the collapse spike pulses another battery. Scaled right (e.g., with big cell tower batteries and a 10-coiler), tests around 2004 by Bedini and Peter Lindemann showed 500% more work provided to real loads on the output batteries compared to what left the input batteries. Experimenters have had mixed results, often due to high-impedance batteries or poor switching. Of course, plenty of folks have pondered motor-generator setups that self-charge—sounds crazy, but utilizing certain principles, there have been many successes, and none of it violates any laws of thermodynamics.
Benitez iterated from basic commutator switching to his ultimate design with a Poulsen arc and mercury vapor rectifiers (MVRs), pulsing DC at 50–60 Hz envelopes containing ringing from the LC tank. That ringing—radiant spikes—overcharges the idle battery. MVRs shine here: virtually no voltage drop and ultra-fast recovery, outpacing even SiC diodes.
Low-impedance batteries help because these impulses dissipate in resistance. For lead-acid, starters have lower impedance (for high bursts) compared to deep cycles (higher for sustained low current). Marine batteries are the worst case—they try to be both starter and deep cycle but never work right. Lithium iron phosphate batteries seem even better because their impedance is so low it’s hard to measure—this is what Paul Babcock found with the successes he demonstrated in his home shop that I witnessed on multiple occasions. It may make results easier, but it’s not the only factor.
Bedini wasn’t only for long swaps; short/high-freq swaps work too. Fast switching intervals runs on surface charge (that “electrostatic fluffy charge on top”), not deep capacity so the batteries don’t run down. John Bedini told me about his intention to start experimenting with high-frequency battery swapping (e.g., 30 kHz) using PIC chips for LEDs and small models, likely with LiFePO4 like 18650s—but he passed within a year or so of looking into doing that.
Benitez’s system needs a fresh look—it’s been hashed out on my forums (energeticforum.com and energyscienceforum.com), which are updated and blazing fast now. They need a little maintenance: I’ll scrub the membership list soon and automate sign-ups (manual process was too time-intensive to keep spammers out). More positive results came from those threads than anywhere else, thanks to authoritative experts like John Bedini, Peter Lindemann, and Eric Dollard personally contributing in mass abundance—a treasure trove they didn’t share much elsewhere.
Peter Lindemann’s 2018 presentation is a great intro (available at Self-Recharging Battery Supply of Carlos F. Benitez). You can start with Benitez’s earliest method (simple commutator) and scale to the full Poulsen arc/MVR setup—post your builds in energeticforum.com to keep the momentum going.
Benitez’s Complete Patent List (Including the Unrelated Fluid Motor)
Benitez filed seven patents (one U.S., two French, four British) from 1908–1918. The electrical ones (1913–1918) build from basic oscillations to automated self-runners. The 1908 fluid motor is mechanical and unrelated—included for completeness. All are public domain; patent numbers link to Espacenet.
Reciprocating piston motor for motive fluids (steam/air) with direct piston-valve actuation for efficient admission/exhaust. Convertible modes; no electrical tie-in.
New Process for the Generation of Electrical Energy
Ultimate: Dual-battery with clock-solenoid switching; motor-alternator feeds Poulsen arc/condenser tank; MVRs rectify ringing to overcharge.
Bedini SG vs. Benitez: The Solid-State Evolution
Bedini SG and Benitez share the same principle: discharge one battery to pulse another with radiant spikes, yielding more than what left the input. Bedini simplified it for modern parts; Benitez used mechanical/early vacuum tech.
Mechanical commutator (early) or clock-solenoids (hourly in GB121561A).
Spike Generation
Inductive collapse.
Poulsen arc chops alternator AC → LC tank ringing (50–60 Hz envelope + kHz ringing).
Results
500% more work to real loads on output batteries (Bedini/Lindemann 2004 tests with cell tower batteries/10-coiler); mixed for small setups.
“Excess electrical energy” (GB121561A); overcharges idle battery while running loads.
Load
Often self-contained (coil as “load”); mechanical work on the shaft for turning fans or a generator for more net electrical gain.
Motors/lights via terminals (40–41); surplus for tools/industry.
Batteries
Low-impedance key (starters lower than deep cycles; LiFePO4 even better per Babcock).
Galvanic (lead-acid implied); modern low-ESR helps.
Note on Capacitors
Benitez used “condensers” (1910s term) and in FR20076E mentioned “electrolytic devices” for structural improvements — but never explicitly “electrolytic capacitor.” The high-voltage self-recharge effect I’ve empirically verified (50–95% voltage rebound post-short) is almost exclusively seen in electrolytic capacitors (aluminum oxide dielectric). This may not be related to what Benitez was doing, but you should know about this. I discovered this effect on my own for the first time around 2002 with a 1200V 0.1uF AC capacitor from a microwave, charged via Bedini SG made from a Sony Capstan (reel to reel) motor. I found that by charging the capacitors with high voltage pulses—whether it was 100V or 10,000V—it changed the properties in the capacitor to act like an electret, where it retained a permanent type of ability to recharge almost all the way back up to the top of where I was charging it. It reached 100V, a neon bulb triggered an SCR to discharge to another battery—and after conditioning, it self-charged to nearly 100V without input. I did this with canister electrolytics charged by oscillating high-frequency ignition coil output, conditioning them to self-charge and self-run the oscillator. My 2007 demo ran indefinitely on two conditioned 33,000 µF electrolytics at 0.6V — proof this radiant “memory” is dielectric-specific and possible that this is one of several ways that Benitez’s system worked even if he didn’t understand that principle. Video of this self-running oscillator is down below.
Low-Impedance Batteries: Why They Help
These spikes are high voltage, low current, radiant impulses. Impedance kills them:
Lead-Acid: Starters have lower impedance (for high bursts) vs. deep cycles (higher for sustained low current).
Marine Batteries: Worst—try to be both starter/deep cycle but never work right.
LiFePO4: Near-zero impedance—Babcock’s demos I saw ran forever on them. May make results easier.

Here’s the old self-running Bedini oscillator video from around 2007-2008:
This is the highest COP replication of a known working overunity system, posted in a public forum, that I know of. Congratulations to Donald H. and we are looking forward to more positive results. I’d recommend reading the entire discussion thoroughly if you want to know how to verify what your system is actually producing. In a way, this is actually historical – not a proven overunity system itself, but a replication with more coming. Although Mike’s self-sustains with higher output, anything over 1.0 COP proves the point and 4.5 is well beyond proving the point.
It’s also easier than one might think. It’s important to discard any myths that a system must completely self sustain or self run in order to show over 1.0 COP performance. On these kind of systems, what is important is to do a discharge test on the batteries to see what their actual capacity is in terms of amps and time. Then, if you can exceed the amperage draw for the hours you would get from both your input and output banks since that is what you’re starting with, then you’ve succeeded.
In 1999, when John Bedini was first introduced to me, this “Glass Case Motor” was the first thing he wanted to show me so it had always been very special to me but it was even more special to John. It is a beautiful work of art that John built because it embodied the many principles that were worked out over the years with his partner from the past, Ron Cole.
The first time he ever presented it publicly was at the 2015 Energy Science & Technology Conference but it was mostly a demonstration along with the history and some of the thinking behind it but he never disclosed the circuit specs, coil details, etc.
John Bedini’s Glass Case Motor – Gravity Wave Space Flux Motor
The interesting or even profound thing about this “glass case motor”, which John actually called the Gravity Wave Space Flux Motor, is that it had run countless hours over the years on 30 year old either alkaline or zinc carbon batteries. The batteries had been seen to be in such poor shape that they were practically falling apart but nevertheless, once the rotor is spun, it picks up speed, turns a propeller shaft with eddy currents, blinks LEDs but the batteries never seem to die.
The long-awaited, full-disclosure that everyone has wanted but never thought would happen is coming to the 2020 Energy Science & Technology Conference.
While we may not be able to claim we know all the answer as to why this particular arrangement of coils, magnets, etc. can demonstrate these amazing feats and we may not be able to claim that we see this motor the same way John did as he had his own unique way of looking at things, you will will walk away with all the information necessary to replicate this historical and amazing machine!

John Bedini’s Self-Recharging Motor by Peter Lindemann, DSc
Last year, Peter Lindemann demonstrated a self-recharging system invented by Carlos Benitez, which is the apparent origin of self-recharging battery systems.
This year, Peter demonstrated a method John Bedini used to keep a battery bank charged up while running his monopole motors. The method had been mentioned in the past in online forums, but nobody seemed interested enough to actually explore the reality to it.
I personally witnessed this method nearly 20 years ago at one of John’s shops affectionately nicknamed the “Palace” because of its interesting interior layout. Below is a picture of the EXACT machine that John Bedini accomplished this with. I also include a 12 minute video where I show you the machine in a video and give a basic explanation of the self-recharging process.
It was done most often with a plexiglass rotor where the coils were on both sides of the face of the rotor rather than at the circumference. It charged a large cap bank, which was then discharged to output bank. A battery was then shuttled back and forth between the front and back indefinitely without ever having to place them on a regular charger to charge them up since the machine and its setup accomplished this.
This demonstration unit that Peter showed kept its battery bank charged up all throughout the conference one one single charge. During the presentation, the monopole is running and he describes how the battery bank is arranged.
RS Stafford is a long time researcher in the energy sciences and knows more about John Bedini’s work than most. He is blessed to have been able to acquire John Bedini’s 6 coiler SG and the large Ferris Wheel Motor.
Here is the goal and why we need your help to raise some donations:
Investigate John Bedini’s Ferris Wheel Hub Motor and Mag amp Motor to get a better handle on how this Tech works. Map out the Magnetic Fields around the various magnets and coils. Document and study all the various values of the components. Add extra Energy producing equipment to demonstrate various concepts that John Bedini has shown us.. And to show case experiments beyond what JB was allowed to show us. Then Bring the Ferris Wheel to the 2020 Energy Science & Technology Conference for a full Presentation.
The below is an excerpt from the full length vendors & announcement videos from the 2019 ESTC.
Bedini SG – Beyond the Advanced Handbook
by Peter Lindemann
Bedini SG – Beyond the Advanced Handbook by Peter Lindemann – This is the first time John Bedini’s 1984 Kromrey Generator has been publicly demonstrated ever and the meters showed that the output was 200% compared to the input. And, the primary KEY piece of information to make it was has been fully disclosed! The Bedini SG that was demonstrated had a self-rotating battery system based on Bedini’s Splitting the Positive diagram and it recycled virtually all of the energy is used to run the energizer back through batteries to charge them up. The amp hours of running time that this energizer demonstrated was way more than the battery capacity can account for. A diode method was also shown that elicited way more radiant energy than the circuit and batteries could even handle, which teaches you that generating the radiant is not the issue because it has always been in the machine from the beginning – the real issue is how to safely capture it! The bottom line is that this presentation demonstrates that what was taught in the Advanced Bedini SG Handbook book is true. Release date – August 9, 2016.

We mentioned that John Bedini would be disclosing something and he has actually disclosed and is continuing to disclose what the Zero Force Motor is, how it operates along with detailed explanations of its working principles. This knowledge that John is sharing is not just applicable to the Zero Force Motor, but opens up the mind to a whole other world of possibilities when it comes to what is actually happening inside of an electromagnetic coil.
This video was posted quite a while back:
Here is another Zero Force Motor that John Bedini made that is at a much lower power but helps to teach the principles.

You may be familiar with 3D Printing and the fact that it truly is one of the most disruptive technologies to surface. It’s also becoming less expensive and more user friendly putting it in reach of more and more people. Some people are already using 3D Printers to create small monopole type motors and other parts for their energy projects and for the most part, many of these devices are actually based on one or more concepts that are protected by John Bedini’s monopole patents.
John Bedini’s 3D Printed Monopole
John Bedini has been researching and testing many different designs using 3D Printers as well as circuit designs that nobody else is working with for these small scale models and he is about to start sharing a lot of his work on these projects here: http://www.energyscienceforum.com/showthread.php?t=3073
John also mentioned that he is doing some work with crystal batteries that is not like anything he has done before and these will be running these small monopoles. Make sure to check out the discussion thread directly above to see what may be coming!
