To reduce the consumption of fossil fuel, people have tried to look for the alternative energy source. Not all of them did their research in a university,complete with ample technology, equipment and sufficient resources to get the job done!  It’s reported that  a number of  people  also did their research in the privacy of  their own home with their own money and equipment. You have heard of them, they are well known as the  “free energy” group. One device that is often  suggested to a newbie is  the ‘radiant charger’. And there is a reason for it , it’s EASY!

A little background on Radiant Energy

There several different meanings to the word “radiant”, “radiant” in regards to the  “free energy” community simply means a type of electricity that is  produced when a coil has lost its current. . This kind of “radiant” definition  is  not generally  used in the academic  field, it’s different from the definition used in  Wikipedia. Some people call it “coil collapse current” or sometimes “BEMF”. *Note that this definition of BEMF is also different from the existing  or more common definitions.

According to Wiki, “Radiant charger utilizes flyback”
“A flyback diode (sometimes called a snubber diode, freewheeling diode, suppressor diode, suppression diode, clamp diode or catch diode[1]) is a diode used to eliminate flyback, which is the sudden voltage spike seen across an inductive load when its supply voltage is suddenly reduced or removed.”

The illustration for the process:


Radiant is said to be the legacy of Nikola Tesla, the promoter of alternating current electricity distribution that allows us to get electricity in our  homes today;  he was also the inventor of many modern technologies.
“The most efficient Tesla Transformations were obtained only when the disruptive radiating wire line equalled the mass of the helical coil. examining the white flames, Tesla realized why there was no measurable “electrical current” at the crown of these activated coils. The normal heavy charge carriers, electrons, could not travel as quickly as the radiant pulse itself. Choked in the metallic lattice of the coil, electrons became immobile. No electron current moved through the coil at all. The radiant pulse which moved over the coil surface, was therefore not electronic in nature.

Additionally, Tesla discovered an amazing phenomenon which removed all doubt concerning the true nature of energetic carriers at work in his apparatus. Tesla arranged a very heavy a U-shaped copper bus-bar, connecting both legs directly to his disrupter primary. Across the legs of this U-shaped busbar were placed several incandescent lamps. The arrangement was a very evident short circuit. The lamps were illuminated to a brilliant cold white light, while being shorted by a heavy copper shunt. Uncharacteristic of particulate current electricity, the bright but cold lamps revealed that another energetic current was indeed flowing through the “short-circuits”.

Those who observed this experiment did not expected it to perform any function save the incineration of the disrupter circuit and possibly of the dynamo itself. Instead of this, witnesses beheld a marvel. The lamps lit to an uncommon brightness. In this simple demonstration, Tesla was illustrating but one of his many evidences. Electronic charges would prefer the least resistant circuit rejecting the incandescent bulbs for the copper path. The current in this situation chose to conform with a contradictory principle. Perhaps this was true because the currents were not electrical. Tesla repeatedly used this demonstration to evidence the “fractionation” of currents electronic, from currents neutral.”

It is known in the free energy community that this radiant will produce a  different type  of charging, this should interest you. It is said that terminating the positive side altogether will produce different effects than terminating  the negative side. The most common design terminates the negative side. There are also some designs that terminate both the positive and the negative side. I have never seen a design that terminates  the positive side.

The radiant produced by the coil will be proportionate with the coil’s inductance. More inductance produces more radiant power. Coils with cores will have more inductance power. However some people choose to not use the  core in attempting to produce a  higher output voltage.

The radiant will also be limited by the inductance. In other words, once the coils have reached  saturation, (when the coil is full) , the radiant output power won’t increase anymore upon receiving more current. The flowing current then becomes a waste or source of heat. It’s a waste of energy and time literally!

The radiant will also be limited by how fast or  how quickly  the current can be stopped (or turned off). If the current is not stopped fast enough, then the power that is stored in the coil will manage to leak into the circuit before the current completely stops, ending up with  less power stored in the coil.

There are many kinds of implementation of radiant chargers. For example Imhotep Bedini Fan, Bedini SSG, Joule thief and many others. The implementation differs mainly in the means to stop the current. There is one that uses  a mechanical switch,  others  that use wheels, one that uses induction, or one that relies  on a transistor or timing chip. Each has their own benefit and weakness. For example, while the mechanical means may produce the best current “cut”, it also  produces spark which is hard to overcome. The spark eventually becomes the major source of power loss. Some people try to overcome the spark by leaking the current from the coil, which actually end up reducing the radiant output.

Most people prefer to build the solid state (transistor and chip) version. Not just quiet, it offer decent efficiency too compared to other version. The wheel version is considered a level up and is only suggested for more advanced individuals, but it’s expensive  and time consuming to build. A kit from  Bedini 10 Monopole kit is sold for roughly $3,200.

Bedini, the inventor:

Bedini is considered the guru in the  free energy community, he owns  several patents for charging technology, but  he allows  the public  to replicate his ideas. He has been know to be quite generous with assisting those who need it and often shows up  on forums such as ‘energetic forum’ and ‘SSG yahoo groups’, as well as his own private forum. This is helpful to anyone interested in building a charger. Some examples of  Bedini’s work are ‘school girl wheel’, ‘window motor’,  the ‘tesla switch’, monopoly, the  ferris wheel (a very big wheel that function as a charger), lockridge motor, Royal Rife healing device replication, crystal battery, self made transistor and  the capacitor discharge charger. He sells kits to help people build their own radiant chargers. He is also known for his state of the art amplifier, Bedini amplifier. Quite the inventor .

Radiant chargers are  very popular among free energy enthusiasts, however the media is never interested. What’s new right? There are tons of videos about radiant chargers on YouTube, but that’s about it, no media stories.  Many people have invested  thousands of dollars  on building  radiant chargers, but the media never heard about it? Is this just another example of  suppression of free energy? You decide.

Unfortunately, this situation has been made worse by theorists. They claim that the  radiant charger is a free energy device, produces more  power than it receives, that it is charging  voltage without current, and  they suggest to reduce the current in order to charge with only voltage.  Fact is  this is false because Bedini claimes that his radiant charger is ” not a free energy device”, but it will do a very good job at recharging battery. He also suggests that the radiant charger (made correctly for 12V load) should produce an output of  1 Amp  with a 1 ohm load, not “voltage without current” at all. The theorists, have in turn caused   a lot of  damage regarding  credibility of the  radiant chargers. The wrong information they provided has give people false hopes and produced false implementation. They do not get what the theorist claim, even when people already spent a lot of money, thousands of dollar or even more, to try to replicate as close as possible. In the end, some has become cynical to the point of calling Bedini a liar.


The popularity of  the radiant charger also created a lot of HOAXES via videos.  They make a fake videos or posts claiming  that a non working device and  is a free energy device and  solution for energy problem, etc. Some  have even gone as far to collect  donations from the public; even  in selling  the faulty device! Be careful!  In the end you are  wasting your  money for something that will  never work. This is why I wrote this article.

My opinion, observation and experience.

Overall, the  radiant charger is a pretty good charger. Some people, including me, were witnessing charge times that are quicker  than what the conventional chargers can produce, so that’s a good thing. You can charge a large battery with relatively small input. You can even revive a  dead battery, making it useful again. Folks  report that they experience  more battery capacity and cooler charging, just like what was originally claimed. No one receives free energy, but people get an excellent charger and rejuvenator that can compete even against the best commercial chargers out there on the market today. Be wise and follow  guidelines  instead of relying advice from the theorist. It is best not to follow  the typical “too good to be true” claims because that’s what they are.  Just follow the original guide lines, and you can’t go wrong. The radiant charger may not be free energy device, but  it does the job. It’s that simple.

What to look out for:

1.Be aware that the primary weakness of a  radiant charger  is that it can kill the battery when the output is used directly.

2.The special property of  a radiant charge can make the battery incompatible with  the existing charger. This has become a serious problem, so serious that Bedini had to replace his charger product method from radiant charging to capacitive discharge charging, mentioned in 20 minutes in this video bellow:

I hope that you find this helpful:

3. Others reported that their battery no longer produces any current. What is strange is that the voltage is still normal, but the battery will no longer  produce it’s original current. As a result, the device that uses the battery stop working or the battery is just dead. If you want to avoid this, check this out, what NOT to do: The testimony can be read here:


I was also experiencing the same thing. I ended up destroying a couple of good batteries, but hey, I did finally find what does work! . I came up with a solution, instead of using a single diode, I now  use a modified full wave bridge rectifier. This seems to work for me. My battery no longer dies.This is what I have used for the past few years:

Here’s my diagram:

Diagram of stingo radiant charger
Diagram of stingo radiant charger


I get  great performance  with this circuit. I can charge two 1000mAh battery within 15 minutes with just 350mA output. Normally this would take  about an hour and a half.  In a mistake, when I charged the  battery that long (for 1 and 1/2 hours) the battery got hot and leaked. Others have reported that charging a 70Ah battery with 1 Amp output will take 15 hours.

For comparison, here is the charging time  using a  commercial charger:
La Crosse Technology BC1000 Alpha Power Battery Charger. For 1000mAh battery, with 500mA charging current, 1 hours 40 minutes.

Ultra AAAAA Desktop Smart Charger 8 AAA 1000 mAh Low Discharge. For 700mAh to 1200mAh battery, with 500mA charging current, 1.5 hours to 3 hours.

Reinaissance Charger, RC-1AU, Fully discharged 1AH (1,000mAh) Battery . . approx. 2-4 HRS


4. The other problem is gassing. Radiant chargers produce gassing faster than a commercial charger. This may be the reason for faster charging. But for lithium ion, this is dangerous, which is why radiant chargers are not recommended for lithium based batteries. Since the radiant charger is a quick/fast charger (even with what is  usually an  acceptable output current), care must be taken  if you  want to avoid gassing. Overcharging is NOT recommended.  Some people refer to this  as “cold boiling” and  they actually let their battery  bubble for hours. That is not good, trust me! Don’t do it.

Here is some more information about the effect of pure radiant to battery, the reason why I use 4 diode and 1 capacitor instead of just 1 diode for the output:
If you want to exclusively use radiant charger, be aware that it may make the battery to refuse normal charging. Also some other problem, like cold boiling. Cold boil is usually called gassing in other field. Gassing is BAD for the battery.


Fast charging is discourage not only because of heating but also gassing. Gassing occur more if the charging voltage / current is higher. Radiant produce gassing faster than normal charger. But this is maybe just indication that radiant charge the battery faster too.

Here is a post from elias who experience the single diode charging problem:

I have been building SSGs and charging batteries for about two years, and the problem I am facing now is the fact that it seems that although the batteries deliver energy more than usual, the voltage level of the batteries charged with Bedini charger decreases under load significantly making devices such as mp3 players, not being able to function.

Don’t get me wrong, the sitting voltage is fine, but when It is put under load the voltage level goes down so much that the mp3 player says low battery, but I know that it can deliver good amount of energy, but the mp3 player thinks the voltage level is what says the amount of energy in the battery is.

The batteries are 1.2v AAA cells for my wife’s mp3player, they worked well before charging with the Bedini Charger. I have also got this problem with my philishave.The battery delivers more current than before I can verify it, but the voltage goes down, when driving loads, and the device “thinks” that the battery is out. I have seen this effect in Bedini’s videos also, his batteries have good amount of energy in them, but the voltage drop is more when driving loads, I wonder.

My comment on that post is before I use partial FWBR. After I use partial FWBR, my son’s nicad battery should last for years even if he use it often, if not because of my mistake of overcharging the battery to literally boil it. I still have some working nicad from few years ago.

mrbrown solution is to use cap to prevent battery’s sickness:

I swap the batteries round all the time with no problem at all on the SSG circuit. You can also do it with the SG cap pulsed circuit and I have been doing this for 4 years, but if you use the SG circuit without the caps and charge the battery directly, the battery changes to use negative energy.

This battery will no longer charge normally and appears shorted when you try.

I was now using a 24v dc supply transformer to power the fan.

When measured by powering a 12v 21w bulb, the 4ah battery lasted 2 hours after recovery. After the charge from the fan it lasted 3 hours. Wow. I recharged it again and placed it back on the motorcycle, it died the same day.

I placed it on a conventional charger and the battery drew 2A, got hot and boiled but would not charge. I placed it on my SSG wired fan and again it would not charge. I then put it on my 7 filar fan and it charged.

The next day I put it back on the motorcycle and it died again but I noticed the battery was hot and had lost a lot of electrolyte. I topped the battery up and recharged it on the 7 filar fan overnight. When I got up the fan was hot and had stopped, the battery was not charged, hot and full of white crystals. The fan was deformed because of the heat but not shorted and the Bedini circuit and bridge rectifier were fine.

I gave up on the 7 fillar fan.

After learning a lot more over the years reading everything I could on Bedini I learned that my output on this 7 filar fan was negative energy and also all the advantages and disadvantages of this form of energy. Bedini’s explanation of what it could do fitted my experience.

With both types the output is measured as less than the input, but when connected to a charging battery the positive radiant usually gives a near 1 to 1 charge rate The negative seams to do something similar but when the battery is discharged on resistive loads the battery seems to have greatly increased capacity. The battery continues to charge after it is disconnected from the charger for some time. The battery has greater self recovery. There are big problems with the negative energy, It tends to crystallize the battery rendering it useless. The battery will no longer charge on a normal charger and appears shorted even before it crystallizes. It is difficult to reverse this negative charging effect.


The most amazing find was to my Li-ion 1400 mAh 3.7v cell phone battery. My phone was desperate for a charge so I though, hey why not. I took the battery out of the phone and put it into the circuit. To my amazement after only 30 mins, and at only about 1 watt of input power my phones battery went from 3.5 volts to 4.2 volts (a full charge) and was room temperature if not a little colder. My normal charger takes about 2 hours to fully charge the phone and it is boiling hot afterwords. But there was a downside to this, upon putting the battery back into the phone, it informed me that the battery I was using was a non supported battery, which means I’m going to Verizon tomorrow and complaining


Hi Elias,
Thx for the reply,I’m not sure what you mean by your comment regarding #20 wire.Are you saying that it does’nt work that well for you.Also,What is the capability of your SSG with regard to charging a secondary battery.My particular setup seems to get a max of 13 volts on a secondary battery using my original coil as compared to about 12.5 with the #18 guage wire.I’m kinda disapointed with the #18 wire.Also I have noticed recently that my batteries dont accept a normal charger anymore and I’m not sure what to make of this, But I do have a 6 battery arrangement that I keep swapping batteries in and out but I’m not sure how far this will take me lol.

And if this is what really happens, then you should see changes in the performance of your batteries, until the point where a stable “Bedini” dielectric layer has been formed. And at that point, the performanc of your batteries with normal chargers should also be much less. Bedini says that “conditioned” batteries can hardly be charged with a normal charger.

John Bedini himself:

It’s ok to not run the load, what you may find is after the battery receives the back charge for a few hours, if you make the cap’s smaller you can charge at a high frequency then you will find the radiant on top of the wire, think Tesla here about his shunts with the light bulbs. Then take the battery out and try to charge with a normal charger, it may be very hard to charge. Peter and I found a change taking place in the battery. Tom Bearden found out the hard way about when he made an appointment to see Bill’s charger, the battery was dead but kept working the machine. However the transistors were Old hokey puck transistors Germanium PNP’s I just made the circuit using NPN’s because I could not find the 108’s. The machine produces a Radiant current on the wires at high frequency it can be used to get power from, Tesla, Tesla.

John B

The three battery system is just a test to show the switching. So here see if you can get this circuit to work and charge it’s own battery. The load must be chosen correctly so the battery is in a state of constant charge. The famous Bill and Ray Scalar charger. Charger is the one I talked about on KABC with Bill Jenkins. Drive it with a flip flop oscillator you can control the speed. Give this a try MR. Jones, I have one of these running at work. If your not careful it will destroy your battery. Also if you take this battery out of the system it will be real hard to charge with a normal charger.

Here is my conclusion:

Single diode:
– battery become capacitor
– voltage without output current
– small starting output current
– high standby voltage
– broken battery

cap in parallel:
– kill the radiant / convert to normal electricity
– battery would still get heated up

my solution:
– battery stays cool
– battery can still be charged with normal charger

rene charger:
– better efficiency
– source must have higher voltage than charged battery

Despite  it’s  weaknesses, in my opinion the  radiant charger is awesome!  If you have dead lead acid or nicad battery, or have the need to  charge batteries often, I suggest you to try it. If you need any help, please let me know! I am here to help! Just pop an email to

Good luck and happy charging!

    1. Thanks for the head up Trinity.

      Felix Ernesto, stingo will self oscillate as long as the output is not shorted. It is better to avoid running without load because it will be a tremendous burden for the transistor.

      I do not know how it work. Electronic simulation software may even fail to replicate it. But many have replicate and get the same result. Here is a half done stingo (without the diode bridge):

      1. thanks man … this circuit is very interesting, and I say it from the point of view of an electronic technician … your design is very intelligent, I will carry it out … again thanks for sharing.

        1. your welcome. Thank you. I found it by accident, because the first version require me to use my hand as the resistor. Since the circuit generate high voltage, it cause a sting, thus stingo.

          The circuit is decent high voltage driver. But I use it mostly as charger and healing device.

  1. Hi,
    Thanks for your nice post and your provided solution.

    Actually i am suffering from the same, the battery build up voltage with no current. i am using fully charged 12V 9AH lead acid as source battery and 12v 12Ah battery under charge, the 12V12Ah wad dead for many year (less than 0.6V before start). i am using the one diode standard charger. i am consuming around 220mA as input @35Khz frequency. after around 20 hours i stopped charging and let battery to rest for many hours then i measured it and it reached around 10.4V (WOW). but actually not able to driver any load. just connect any load the voltage drop to almost 0V, just remove load the voltage return again above 10V. even i can short it direct with a wire and the same happen voltage drop and up again after remove wire.

    I think this battery has built up of just charges on side plates with actaul chemical reactions inside.

    i started to modifiy my charger (555 timer + IRF840 Mosfet).
    the coil is 1 ohm DC resistance 260T of 0.7 mm wire. core is a plastic pipe of 20mm dia and 50mm long. just air core.

    i arranged to have capacitor of 3uF 2500V, and started to charge again and will update for the results.

    for the diodes i am using UF5404 (6 pcs) as your drawing.

    1. Yes, a lot of people experiencing that problem. I think you can not restore the battery unless you do a chemical change (hot water, cleaning electrode, etc).

      I think you should use ferrite core for stronger effect. If you want better result, use other mosfet to drive the mosfet for sharper turn off signal.

      My method is not the only solution. The other method is jouler ringer or ringo charger method, where the load is placed between the source battery and the coil, one diode still go the load positive. The source voltage must be higher than the load. The only drawback is the charger no longer flexible.

      1. Thanks Sucahyo for your reply, i tried Ringo charger but actually not working unless the load battery has initial charger but if dead battery so current does not follow and complete circuit not work (no voltage arrive to the coil).

        From your experience which is better for battery restoration:
        1- low freq as 500 – 1000Hz? or higher freq as 35Khz?
        2- low output voltage pulses as 90V? or higher as 300V?
        3- if using Gel battery, is there any special treatment?

        Appreciate your time reading and answering my clarifications.

        1. Ok. I see, I forgot about that problem for ringo charger.

          Make sure that the dead battery still has proper electrode (not corroded nor shorted)

          1. sharper power off signal is better. Higher coil inductance is better.
          2. sharper power off = higher voltage, can produce more than 1 kv in the primary, unknown voltage at the secondary.
          3. add distilled / demineralized water.

  2. Hey Sucahyo…. I just made the charger using your schematic ( that with 2 toroidal coils …I set the potentiometers to have high pitch of coils , high frequency still in audible range) and lowest consumption
    ( around 500 ma at 12 v ) to not heat the transistors….my transistors geting hot at lower frequency and around 800 ma -1 amp consumption..also I am using heat sink for transistors …I measured the output and I obtain a maximum 88 V and 100 ma ( if i send the charge to a high voltage 1000 uF capacitor, the V rise over 100 v in few seconds …so can you please let me know what consumption you have at your circuit and the output charging curent? If my 100 ma are to low for charging , maybe I will need to lower the frequency to have a higher charging current…I am afraid about my transistorrs to not burn them upp …I used TIP 42 and TIP 41 transistors…

    1. Hello,

      The circuit may need fan if you want to use more power. Output charging current usually halve the input current.

      The current required for charging still use the charging standar. Minimum C20 (5% of battery capacity in amp hour), maksimum C1 (same as the battery amp hour). So the output current will depend on the output battery capacity.

      For stingo with two coil, I think 2 Amp input at 12V is safe if you add fan.

  3. Hi …..I have some unclarities about circuit you posted…
    ..why you are using 3000 volts capacitor if this circuit have coils with low ohm ( 1 ohm) resistance … at this value , you need low number of turnings with relatively thick wire ; so we will have low voltage at the output coil
    at spike momentum….

    1. With new component, the circuit can produce more than 1000V with 12V source. With 2 x 1.2V, it can produce 75V:

      The output will be greater with lower the coil resistance as long as the inductance is sufficient.

  4. Mas Cahyo, I,’m also interested in buying your radiant charger. could you please email me? I live in jakarta by the way.

      1. Hi, Sucahyo, I,’m also interested in buying your radiant charger. I need charge 2 super capacitor (500F/16V) frequently, would you please email me? I live in Taiwan Taipei. Thanks!

  5. Mas Cahyo are you selling this radiant charger ? I need it to charge two of ordinary lead acid 70 AH and 100 Ah car batteries quite frequently. That will be great if i can get it from you, i live in Jogja. Thank you very much and have a great day.

      1. Mas Cahyo

        bisa tolong email ke saya harga stingo nya

        dan cara penggunaannya – apakah used lead acid battery bisa di rejuvenate dengan stingo ?

        Jadi Bedini kit yang dijual itu tidak berfungsi ya ? (yang ada di the complete beginner’s handbook)



        1. Ok. tidak semua batre bekas bisa dikembalikan. repotnya banyak yang rusak / keropos selnya sehingga tidak bisa diperbaiki. Yang di bedini kit adalah demo saja. Terakhir saya tahu bedini kit itu yang jual dua. yang satu bedini yang satu rick, dengan pendekatan yang berbeda.

          Not all used battery can be recovered. Some battery have corroded cell that will be impossible to recover. Bedini kit is not a proof on concept but it is just a tool to know that bedini SG is. I never heard anyone get success from them. Anyone that did make it on their own, but only a handful. There a lot more people that fail. I think the key is geometry and material.

  6. I have also been using the pulsed solid state circuits for battery charging which seems to work very well. I have also made circuits to allow me to charge the same battery that produces the load power without an aid of another battery.
    Thank you for this site.

  7. Hi,
    It’s been a while since my last question. I have rearranged my set-up. I now use a positive drive sequence creating an oscillator. The coils are running around 1250Hz. I do a cap dump of about 8 amps every second. I have not balanced the circuit yet to create a balanced load output. I am showing 1.5 amps into the coils. If I reduce this I get a slower dump period. My batteries are depleting quite quickly, but, also they charge quite quickly!!! I swap the batteries at 12.5 volts essentially, all they are doing at the moment is charging each other! So I feel I am getting a progressively weaker set of batteries as the charging time are getting shorter.

    On a different subject, the cap charge. I am discharging the cap at 24v into a 12v battery. Change the size of the cap and change the duration of charge. simple logic is proven. However, you say that the radiant effect is eliminated when using FWB and cap for charging. As the voltage on my caps can increase up to 115volts, where is this additional energy coming from if not from the radiant component? I look forward to your comments.

    Thank you

    My batteries

  8. Hi,
    I have been using an energiser with a flywheel for a short period. The batteries I used were 12v gel. Having read that Gel were OK to use. I am not so sure now. there has been a rapid decline in the efficiency of my batteries. I am at the stage where they will climb to 12.6 volts quite quickly with an external charger – within the hour from rapid depletion: where the circuit shows them at 8.5 volts under pressure to run the energiser.

    As soon as they are charged, I can use them only for a few minutes before depletion sets in. I now consider the batteries to be useless. I am thinking that the gel has crystalised and have read that this cannot be reversed in gel batteries.

    If true, more needs to be done to inform those spreading bad information.



    1. Yes, it is unfortunate that the effect of radiant charging to battery is not properly documented. Some people even suggest gel battery for the experiment.

      Radiant charging produce more bubble than normal charging method. While this may be beneficial in HHO electrolysis implementation, in battery charging this is damaging and can be dangerous. The reason why overcharging is bad for normal charging is because it will produce bubble, usually called gassing. Gassing will convert water to H2 and O2 gas. In gel battery this will reduce the electrolite which resulted in reduced capacity. In lithium battery this can be very dangerous since it may lead to fire break out when it leak. In radiant charging gassing occur much earlier. So gassing may occur even when the battery still not full yet.

      That is one reason why I use 4 diode and 1 capacitor for the output instead of just 1 diode. By alternating radiant with normal charging will allow fast cool radiant without damaging the battery too much.

      Note that Bedini suggest wet battery. I now add the battery problem at the article.

  9. Hi guys, really enjoyed reading these comments on radiant energy battery charging. Do you have any v max 10iews on capacitor discharge method of charging. I use 12v lead acid batteries charged from PV panels max output 10 amps in direct sunlight…In the UK never get consistent sunny days so charge rates vary day by day. Forever looking at better charging methods to get the best from my panels in avarge light conditions.

    1. I believe that capacitor destroy radiant. If we use capacitor as temporary buffer, then at the same amount of output power, the battery will be a lot hotter than when using the radiant charge alone. But the charging speed may increase. I believe that capacitor discharge is the same as normal electricity and different from radiant charging. BTW, the current line up for Bedini R-charge product use capacitor discharge because of incompatibility problem with normal charger. Previous version use radiant but it create problem, the battery would then no longer able to be charged with normal charger. I observe the same problem with my earlier design which is why I now use 4 diode and 1 capacitor at the output.

      For solar application, I think the best method would be direct / pulse charging during maximum exposure and radiant charging during low exposure. It would be better if you can adjust the power output of the radiant so it will perform harder during low exposure (in the limit of transistor).

      Please also read this article:

    2. Sucahyo, sorry for not coming back here for a while. Thank you for taking the time and trouble. I have various radiant type chargers with similar circuits and will incorporate the extra diodes as you have done. Kind Regards

      1. Ok. Try to measure the ratio between output current and input current for all the charger that you have, despite the claim, the charging speed is still proportional with output current. Use 1/35 battery capacity at minimum. 1/1 capacity max.

        Good luck.

    Thanks for your kind reply.

    I understand your arguments and I´m not criticizing your charger circuit.
    My point about “radiant energy” is linked to “free energy”.
    The misconceptions about energy are spreading in internet, sponsored by people like Bedini, Tom Bearden & others.
    Their claims are full of errors.

    In his 1901 patent, Tesla explains what is “radiant energy”: light, cosmic rays, X rays or any kind of electromagnetic and electrostatic energy also.
    The source of this radiant energy is primarily the sun.
    Tesla made another explanation, that his invention was not a kind of free energy or perpetual motion machine. Simply a machine that captures an already existing energy in the environment.

    In that time there was not a clear understanding about electromagnetic waves (radio waves), neither about the atomic structure.
    Maxwell proved theoretically in 19th century that light is an “electromagnetic wave” in a range of frequencies.
    Tesla was a visionary, and his idea is present today in electric solar systems that captures “radiant energy”, in other words “the light”.
    Another kind of his “radiant energy” is electrostatic produced by the atmosphere. Basically in ionic form, that can be collected by a suspended plate and charge a capacitor.
    Many researchers and scientists studied this phenomena and implemented some devices that worked. Although until now, it is not so efficient and practical like solar panels.

    Concerning the Tesla demonstrations, illuminating light bulbs.
    This could be spectacular in early 1900, but not so today.
    One can light a lamp without wires, placing near a radio transmitting antenna. This phenomena is well known and perfectly explainable.
    At high frequencies any solid copper wire will have a large resistance due the skin effect. The current will flow only at the surface of conductor.
    Hence, a copper bar was not a low resistance path and also had inductance. So, things must be considered carefully.

    Switched power supplies working at 100 KHz are usual.
    This power supplies use to have current control.
    A low value, non inductive resistor is placed at the current path, producing a voltage (V = I * R). The voltage is compared to a reference and control the time of conduction.
    There are technical procedures to measure this pulsed currents with oscilloscopes. All this is normal and achievable.
    Everything is inside the theory, there are formulas, measurements and calculations. The actual technology is solid and works perfectly.
    So, to an electronic engineer sounds weird to read that the current cannot be measured because oscilloscopes are not to be trusted.

    My advice to you is to continue performing your experiments, but also deepen your knowledge on the electronic theory.
    This way you will be free from false information which are disclosed by people interested in mystify the truth.

    Best regards.

    1. Thank you for sharing your knowledge.

      I just trying to let you know that charging with radiant method can be more efficient than conventional method, but unfortunately most people go to the wrong way.

      Yes, it is very important to test any theory for ourself. Many of the theory circulating around in free energy group or forum are just simply wrong assumption. Unfortunately many people blindly apply them without ever verifying the theory. As result many people fail without even know what is wrong. Many make empty promise to others and drag many people down, make people waste a lot lot of money without ever producing result.

      The kind of energy I am interested in is from this experiment:

      The sudden quick closure of the switch now brought a penetrating shockwave throughout the laboratory, one which could be felt both as a sharp pressure and a penetrating electrical irritation. A “sting”. Face and hands were especially sensitive to the explosive shockwaves, which also produced a curious “stinging” effect at close range.

      A friend of mine that once do study tour to power company also tell a story of it.

      I am also interested in this:

      1. Hold Your Ground Sucahyo!

        There will always be academia that points to their standards and laws and electronic theory, and there is reason for that, because it describes almost all that we build in electronics.

        But not all! There are little indications that make you wonder about the monolithic accepted explanation of how things work. If you can prove one of these equations doesn’t measure up, or describe what seems counter intuitive what does that say about what we believe is true?
        Remember, we don’t really know what an atom is, and we can’t decide how a field works. We can just predict how they behave.

        Here are some examples that make me wonder: Take a simple pulse motor driven by a transistor. Why is it that you are using energy to drive a transistor to pulse energy through the circuit, thus having current, resistance and therefore power needed. That means some wattage dissipated in heat through the transistor, and other components. People who play with a pulse motors will tell you that it’s possible that your transistor is cold to the touch. How does that happen?

        Another is the equations for calculating the magnetic field of a solenoid. Where the strength of the field is based on the magnetic permeability of the core. So a ferrite should give you many more times the magnetic field than an air core. But then use instantaneous pulses and you will find if you insert a magnet inside an air core it will push many times harder than any core material that extends to the end of the solenoid. This is the basis for the Newman motor.

        I believe that Maxwell was a genius, but there are some that believe that Heaviside might of missed something or the release of the reformulations were purposely embellished. Another conspiracy theory, anyway.

        The point is, if we are so knowledgeable about how the physical universe works, why do we not have the same command of electricity that Tesla had a century ago, given all our modern technical/compute prowess?

        1. Yes. Interesting observation.

          I too can not find an explanation why with the same circuit, can produce different effect to the battery. Even with the same output current, why a sharp radiant charger can charge 6 times faster than capacitor dumping method. Why battery stay cool. Why the bubbling happen much faster, etc.

            1. Yes, no doubt. Different signal product different effect. The effect to health can also change too. Which become a problem now because no one investigate the relationship.

    2. Nathan,
      Thanks for taking the time and effort to at least advise these ignoramuses, nothing of which they present is new to a power electronics engineer, and much of what they claim is either demonstrably false, is obscurantist, or is entirely unbacked by evidence having any standard of rigor whatsoever.

      They remind me of technicians who are “smarter than engineers” yet make fools of themselves by failing to even speak intelligently, using technical language in nonsensical ways, and show no signs of understanding the basic principles of electricity and magnetism.

  11. Thanks for your repply.

    I agree, controlled pulse charging methods can be faster than usual continuous (DC) charging. There is a lot of pulsed chargers in the market.
    But you must compare the currents at the same RMS (Root mean square) value.

    What I have seem in SSG posts, is measuring pulsed currents and pulsed voltages with common DC meters, that is wrong. Complex waveforms must be measured with oscilloscopes and the values need to be calculated most of times.

    Before one claim that the battery charge is full, it is necessary to know what is and what was the real state of charge (the SOC). One must know by the factory specs what is the voltage in full charge, know the discharge curves also. The battery must be discharged with a constant current to know if it was fully charged and know the total energy spent. Without these informations is nonsense.

    Charging batteries with high voltage spikes makes the battery voltage rise fast, even boil (lead acid). Above certain value that can be harmful to the battery, because the battery needs time (diffusion process) to accommodate the ions. The voltage will drop fast if the battery was not fully charged.

    I have worked many years with switched power supplies and inverters, projected transformers and inductors (plus 50 KHz) and never saw any circuit with COP >1. Losses is everywhere.
    For me, the SSG wave form has nothing new or special. It is not a new kind of energy. As I said, the SSG energy can be measured and calculated.

    I will show how.

    To know the SSG circuit effiency or COP, you can use a super capacitor or bank of capacitors as the load at the output. You can start with a 5V voltage already loaded in the capacitor.
    Mark the time and measure the voltage on the capacitor until the voltage reach the load limit (12V for example). The energy stored in a capacitor is E = 1/2 * C * V^2 Joules. Assuming for example that the capacitor value is 1 Farad. Then the energy supplied during the charging time will be: T = 1/2 * 1 * 12^2 – 1/2 * 1 * 5^2 = 144/2 – 25/2 = 59.5 Joules. Divide the result by the time in seconds and you will have the power in Watts.

    Place a capacitor charged with the battery voltage at the input and another capacitor (with less voltage) at the output. Make the measurements, time and voltages in both the same way I explained before. Make the energy calculation in both capacitors during the time. You will know the Energy/power supplied to the circuit and what is the Energy/power delivered to the output.
    The circuit efficiency will be: COP = E delivered / E supplied.
    Doing right you will find the SSG circuit COP is less than 1.

    Now, let´s talk about batteries.
    Due to the internal resistance, batteries spend energy to charge and to discharge and also have COP<1.
    To charge the ions must be moved. Ions have mass. To move the ions you must apply a force. Force= Mass * Acceleration and Work= Force * Displacement. Energy = Work. It is classic Physics.
    Nothing wrong, it is how Nature works.

    You can measure the batteries charge and discharge COPs also. Only it will take more time, the batteries data sheet and a constant current circuit to discharge. Plot the graphics, take the time, measure the voltage and do the calculations. You will know the total energy and the charge and discharge COPs.
    It will be less than 1. Everything is all right.

    Everybody is celebrating the radiant energy as a new type of energy. Although Maxwell had already explained this in 1865, the electromagnetic energy is flowing thru the space or vacuum (ether in his time). The Space (vacuum) stores and delivers electromagnetic energy. The energy is in the space as a field.
    As Heaviside said, the conductor is actually an obstructor and only directs the energy to the load. The metallic conductors have resistance (and skin effect),. The resistance rejects electric energy transforming it in heat (Joule effect).
    All of this is not new, and is present in the mainstream Physics and Electronic Engineering.

    As I said before, Mr. Bedini is a smart guy. He saw the opportunity and took advantage.
    But there is no need of mystical explanations.
    Is better to say: Hey guys I discovered a more efficient way to charge batteries. It is 99 % efficient. Look, this is my measures. Let´s do some some tests and calculations.
    And show the data.

    The world is waiting.

    1. Thanks .

      Most radiant charger implementation is different from my stingo charger. Most people believe in “voltage without current” theory. So their charger only produce small output current, under 100mA even when it consume more than 1000mA, most people do not even measure their output current. This resulted in very poor charging capability that end up make them disappointed. My method is a bit different, I use considerable amount of current.

      Real voltage going to the charged battery is not the same as the battery voltage. Some people use it to measure their charger and get the wrong impression. It is wrong to calculate the output power with a battery or a capacitor, it must be done with a resistor as the load (or other resistive load). For example if we use a battery as the load then the meter may show 100mA and 12V, resulting in 1.2 watt of power, but when we use 1 ohm resistor as load (or similar value as battery internal resistance), the meter may still show 100mA but with voltage much smaller than 1 V.

      The method to calculate COP with constant charge and discharge current can be wrong too because radiant charger will change battery capacity, some reduce it, some increase it. Also charging or discharging battery with different current rate will have different efficiency. The other problem is radiant charger can not produce constant charging current.

      Yes, radiant charger make battery boil faster, overcharge will be more damaging. So it is better to avoid full charging and only go to maybe 90% full.

      I use my charger to charge two 1000mAh 1.2V nicad batteries. I only use the batteries for digital camera for now. The digital camera will have much longer run time with 10 minutes stingo charging than 12 hours cheap charger. I once used the batteries to a small mini4wd toy car for my son. It was something like the picture bellow. 10 minutes charging with stingo charger allow more lap than 12 hours charging with cheap charger. The battery temperature also stay cool, especially if compared to the charger service offered around the track. The charger in the track will charge the battery faster, at under 5 minutes, with the battery temperature become hot enough to hurt people’s hand, but will have less lap than when I charge using stingo charger.

  12. Sorry, but what I´m going to say maybe will drive you crazy.
    The so called radiant energy is a myth. There is no difference from any ordinary electromagnetic phenomena and it is fully explainable by Maxwell electromagnetic theory. That is well known in Physics since a 100 years ago.
    It doesn’t matter if a pulse is narrow and have a short time, or the current is low (even pico Amperes or less). The fact remain the same, there is a voltage and a current in a time interval, so there is a limited energy amount. This energy can be easily calculated and measured. Mr. Bedini can say that energy cannot be measured, that there is almost no current, say that is magic or a new type of energy, but the current is there! To prove is simple, connect a capacitor after the diode and observe, it will charge.
    Mr. Bedini knows that and never claimed that his device is over unity, because he is not a fool.
    But he did another claim that he never explained or proved clearly: from 1 battery in the input, the output can charge 4!

    One less educated person (in Electronic or Physics) can take his claims as truth and believe that the batteries will be charged in full (100%).
    At first sight it may sounds strange, but he never shows the data!
    He never mentioned the Peukert’s effect. Never informed what is the brand of the batteries he used nor the capacity in Amps/hours (C20). Never informed what is the battery type (flooded, gel, AGM, etc). Never infomed what is the SOC (state of charge) of the charged batteries. Neither informed what is the discharge method. Etc, etc, etc…

    Off course, all suppressed information contains the truth.
    Let me explain in depth.
    For example a battery with a capacity of 20Ah (in C20 discharge rate) and with a k of 1,5 (a flooded lead acid batery) will take 632h to discharge by a constant current of 0,1A. The battery capacity at this discharge rate would be 63,2Ah (C632). This is 3 times the C20 capacity, meaning 3 times the nominal (C20) energy! You see, the energy was already there from the begining!
    Efficiency is the key, not radiant energy or something magical!
    Mr. Bedini is a smart guy, but it seems that his knowledge in electronics is poor. Measuring pulsed currents at high frequencies with a common dc ampere meter? Clearly an error! And another misconception: electric current is about electrons running in a conductor.
    Looking at the SSG circuit anyone who works with electronic circuits, even a technician, can see that it is obsolete. 2N3055 was created at 1960. Bipolar transistors are not suited for the commutation job and waste a lot of energy.
    To a pro make the so “special” waveform is easy. Nothing special, piece of cake. There is no need of permanent magnets, motors of any kind even that gigantic coil (that he considered so spectacular). To measure the circuit efficiency without a oscilloscope is easy too.

    That is the denied truth; In Bedini´s SSG there is no over unit, no special kind of energy and no magic!

    1. Thanks. What I present is not overunity, but a way to charge at a much faster rate than normal charger.

      Yes, using less than 1/20 of the battery capacity will allow much longer running time and using near the battery capacity will produce a much shorter running time. However, your explanation can not explain why I can charge a completely depleted 12V 7Ah battery under 5 hours with just 500mA input current at 12V. Or why my charger is almost 6 times faster than available of the shelf charger.

      I have a cheap chinese charger at home. My digital camera use two AA 1000mAh battery. Charging with the cheap charger would take half a day, with the battery get hot at the first hour. The result with cheap charger never reach the capacity / running time of 15 minutes charging with my self build charger. Another important thing is the battery will be only slightly warm, still cooler than human body. Normal electricity theory would dictate that a much shorter charging time produce more heat. But in my case, the battery is much cooler during 15 minutes charging compared to the cheap charger 12 hour charging.

      Here is a reference for current battery charging technology:

      The common approach for faster charging is by using higher charging current. Pulse charging method allow charging current 5 times higher than the battery capacity when the battery is empty without producing too much heat. Here is an example of faster charging require higher charging current:

      2 Amp Xiaomi charger take 1 hour 43 minutes, 4.5 Amp OPPO charger take 1 hour 20 minutes. Faster charging use charger with higher current output. OPPO also use special battery technology to improve charging speed. Charging with my charger should be much much faster at that kind of charging current, to the point of dangerous. I strongly suggest anyone to only use half the circuit (only one coil active) at low power setting when charging a cellphone battery. I think 1 hour 30 minutes can be achieved by my charger with 500ma charging current, maybe even much less.

      The drawback is the charging controller do not yet implemented, so the above circuit can be dangerous to be used to charge cellphone battery. It lack the mechanism to stop charging when the battery is full, so you must monitor the battery voltage or use timer when you use this charger.

      I believe that radiant charger is charging technology for the future.

  13. Okay, I think I get what you are saying. The PNP can be turned around normally but will produce a power amplification effect on the base of the NPN which is the opposite of what you want. By compensation you can put a suitable resistor on the NPN base, but this is wasteful. The function of your circuit is to turn on the NPN just long enough to turn off the PNP and in turn QUICKLY turning off the NPN again, thereby producing a sharper spark. I think this could be better designed for the same effect using a FET, but I allow it may just possibly work though it “shouldn’t”.

    1. What I know is if inverted PNP version consume 500mA, then normal PNP version will consume about 2A. But the circuit will still produce the same amount of output.

      The behaviour of stingo is different from most radiant charger, stingo consume less with more load. Stingo will stop oscillating if the output is shorted. Open load is the worst consumption so stingo should not be run without load..

      Other properties:
      – 1% duty cycle at any frequency
      – work between 1.5V to 15V (depend on transistor specification)

  14. By working in “inverse mode” it effectively reduces the
    base drive to the NPN Switching Transistor thereby
    preventing it from being overdriven.

    Said “inverse mode” reduces the base drive to zero, therefore preventing the NPN switching transistor from turning on at all. 😀

    1. I can’t explain it, but that is how I use it in reality. The people who did replicate did mention how strange it is.

      There are people who tried to use the PNP in the correct way but they get worse efficiency instead.

      Please read what people said in the forum link.

  15. Please advise, I am looking at and attempting to simulate your stingo radiant charger circuit and it does not appear that the base of the TIP41C NPN transistor is receiving any power here. The only connections to it are by a reversed bias emitter of the TIP42C PNP and a reversed bias diode. So it does not appear obvious how current can flow at all.

    1. The discussion of the early version can be read here:

      I am no longer a member of that forum but it would be a good reference. SeaMonkey explanation for the use of transistor in stingo:
      “The PNP Transistor is connected to operate in what
      is known as “inverse mode.” The Collector is functioning
      as the Emitter and the Emitter is functioning as the

      By working in “inverse mode” it effectively reduces the
      base drive to the NPN Switching Transistor thereby
      preventing it from being overdriven.

      The Current Gain (Beta) of a transistor in inverse mode
      is approximately 10% of normal gain.

      To attain the same effect with the PNP Transistor
      in normal mode a variable resistor could be connected
      in series with the NPN Base lead in order to “tune”
      base drive for maximum efficiency.

      There is nothing wrong with “inverse mode” operation.
      It is seldom used but a good “trick” to remember when
      it can be taken advantage of.”

  16. Nice simple explanation. 🙂

    I will be controversial here hehe.

    Some of these free energy devices do indeed produce an excess of energy output. For example the Bedini simplified schoolgirl motor (wheel) and the imhotep fan (a miniature version of the Bedini) both will produce an excess of energy if you follow the instructions carefully.

    Typically they will charge a battery at 90+% efficiency or a little better, but everyone forgets about the motor power. This power is around 20 to 30% of the input so when you add both these outputs together you have 110 to 120%. That is you get 10 to 20% more out than you put in, so you could say that 10 to 20% is free energy. OK its not a lot but it IS there.

    No energy has been created to do this as far as we know, it could be the radiant energy from the environment that has been collected in the process.

    Go on build and test one and you will see.

    Take care Sucahyo my friend

    1. Thank you.

      The problem is most people take it wrong.

      A friend had spent thousands of dollar to build Bedini monopole with commercial wind turbin component and expect that he can charge two battery with single battery. He failed, he can’t even properly charge battery. He invest on some brand new 70Ah battery, but still get discouraging results, even after following the popular suggestion to the letter. But it seems he still trying to pour money into the project.

      That represent the current trend of radiant charger implementation. People expect something big. when in reality it is very very very hard.

      1. yes it is difficult. I found it smartest to build the bedini wheel until I completely understood what was happening and only then to expand on it for my own uses. Until one doe3s this they will thriow money away.
