Flyback From Generator Coil

[gconol]

This video is old, so how is your project doing now ? Have you ever achieved overunity ?

[teslata00]

It's not a neon light, it is a LED

[codygillespie]

@teslata00

No, it is defiantly a neon. Part # 272-712 from radioshack. Thats how they come from the shack. They also have a resistor in them to be used with 120V. It would have lit much brighter had i taken it out.

[putu35]

hi cody...nice video.

i know nothing of electronic but i'd like to make it to charging something.

question: were you using air core coil or iron core coil in that video?

[codygillespie]

@putu35

iron core with those weak ferrite magnets.  Also gives it a higher inductance

[rainmanp7]

BINGO ya gotta love it :) awsome stuff "yes i want to get the crap shocked out of me" hahahahaa good stuff.

[guicapone2]

how are you able to short at the right moment of the spike????

[sloppyoscar]

I'm pretty new to all of this and have a question -- it appears that the smaller magnets opening and closing the reed switch are lined up with the larger magnets that induce the coil. The reed switch is wired into the dc output of the rectifier. It must be receiving this voltage and when it opens up it "delivers" the additional voltage we see on your meter? I believe that is the spike you were showing on the drawing. Am I right? Very interesting video btw

[UrCoffeeTastesToasty]

you got it, make it lenzless by locating the reed to switch on at the rise of the wave and shut off at or before the peak. I measured rotations per second decrease only 60 degree of rotor(one magnet less per second). no matter what rpm, volts/currents you pull from it with the short you make(electron flow).

Maybe that can even be decreased to totally zero drag. thus a like somebody said out there.. a perpetual motion machine, opposed to what the other guy said, that works ;). good luck

[josephdupont]

sounds like a lawnmower magneto.... NO?

[josephdupont]

sounds like a lawnmower magneto.... NO?

[HorizonDelta]

Good stuff...more Tesla video in "Tesla cold electricity" by HorizonDelta ;-)

[waltermouthoh]

I am a bonehead about electronics so please forgive me. What I was wondering is if you could charge a battery with this or a bay of batteries. For example, a small unit hooked to your bicycle recharging 10 or 20 of your AA or D batteries. What do you think? Full charge in 10 minutes? (like I said I know very little about electronics, but from what I know about what they're teaching in schools, that might be a plus.)

[codygillespie]

@waltermouthoh

Well sure you could use it to charge batteries running from your bike, but i would probably just use a standard generator on your bike to charge them for ease and assurance of desired output. I dont completely see everything the way school teaches it either, but for the most part i would say it would be very wise to pay attention in school.

[henrykay01]

What is the point of showing a supposed perpetual motion machine that does not work?

[codygillespie]

@henrykay01

Perpetual motion? Never said anything about that. Its flyback from a generator coil.

[henrykay01]

@codygillespie I guess I was misled by the title - Tesla had a patent which says something about radiant energy and free energy.

[codygillespie]

@henrykay01

Sorry, i know the title is goofy, i may change that. I know the patent you speak of and have experimented with it, its an interesting device. Most Hams are aware you have to be careful when touching an ungrounded antenna as a HV charge will build on it. Its that same effect put to use. You can basically think of it as a device that collects static electricity from the air. Its not perpetual motion, its more like a windmill or solar panal.

[codygillespie]

@henrykay01

Perpetual motion?  Never said anything about that. Its flyback from a generator coil.

[transfusablepng]

Free Energy is real and its here! The Oil companies are doing everything in their power to stop these information. If you want a Free energy machine do a search in youtube for the LT MAGNET MOTOR , Join the revolution!

[Milferno1]

hey did you know that you can get the same voltage from water? if you do, then you may be able to apply it to your device and maybe you can get over unity. 

[koneheadx]

TRY 5 times at peak

you will get 5 times more power and matners will be "confused". Busts lenz law and increase power in huge amount.

you really cant measure current at same time as you do this...you have to calculate jules in cap - the ammeter will snub the effect!

Also if you use solid state swticheing, the internal resistance of most will snub it too but reed swtihces work and mechanical ways too..

Ismael Aviso uses IGBTs (lowest resistance) and special RF filters on their gates

[overunitydotcom]

Hi,

maybe try a small motor to run on the charged cap, that will drive the wheels !

Maybe your spike is producing enough power, so a small

motor can run it ? This would be then a selfrunning system !

Good luck !

[codygillespie]

@overunitydotcom

I really doubt it, but i suppose i cant say for sure until i test it. Obviously to overcome the losses in the motor and all resistances would require a decent amount of "overunity". I just dont think its happening in this rig.

[brahmabullsj]

It's my opinion there is power amplification; albeit, very briefly. The amplification comes from reguaging parameters of the circuit - increased resistance in this case. A change taking little work. When the circuit is broken resistance rises from nominal values to very large values because of Ohm's Law. Voltage and current must change to compensate. This is why Tesla fixated on fast switch breaking circuits. Please see my previous post. Nice experiment Cody it was helpful.

[codygillespie]

@brahmabullsj

I took a look at your theory, interesting ideas. I have heard similar things but i have never seen ohms law put into context with it, interesting. Ill keep it in mind.

thanks

[brahmabullsj]

I published a paper that describes the nature of the effect. If your interested, do a Google search for "The Secret of Tesla's Radiant Energy and Overunity Power Explained".

[valllhalla]

now have 2 caps one charging and one dumping the potensial to a battery.

The secret is to switch the charged cap completely off the charging unit, when dumping it to a battery.

[coldfusion1111]

Nice video. Suggestion: You need to show current measured in standard method, and then compare it to the current measured with the capacitor later on. My hunch is you are amplifying voltage but a current drop is occuring. However in both instances total Power = IxV is the same.

[codygillespie]

@coldfusion1111 your hunch is exactly correct. I in no way suggested that there was any power amplification or something, sorry if i was confusing. I believe you can find the same basic effect in magnetos in small engins.

[trance183]

Probably the simplest most clear video out there on youtube. Thank you!

[brahmabullsj]

Hi Cody. Thanks for the experiment and sharing your results. I have a related white paper explaining the effect you might find interesting. Google for "The Secret of Teslas Radiant Energy and Over Unity Power Explained".

[johnb003]

Very well presented, however I wasn't clear on which kind of reed switch you're using. Is it normally closed and the magnet opens the switch, or is it normally open and the magnet closes the switch?

[codygillespie]

Its a normally open switch rated at 1amp.

[koneheadx]

I got this from testing a mullergen by "shorting" coils with reed swtich, and cap suddenly had X20 volts!

Swtihcin at peaks is key. Also very short pulse width..

I like to say this works becasue the coil collapses "within itself" and rebounds with a vengeance when switch is opened.

Those reed swtihces will fry from that arc - you can pull off that plasma arc with dioes into cap too.

i like to use a FWBR (fullwave bridge rectifier) instead of single diode as shown here - catch it both ways.

[codygillespie]

Hi Doug,

Good to hear from you. Thanks for setting the record straight on how you came up with the technique.

[koneheadx]

Hi Cody

thanks for doing the video!- I always try to get people to :"short" their generator coils at the peaks but only a few people so far have actually tried it to confirn the extra power it makes

Ismael Aviso clips "pickup winds" around his high voltage motor coils FIVE TIMES at the peaks!

twice before Top Dead Center, once at TDC, and twice affter TDC - he uses very fast swtihcing to do this.

if you use one diode, fill TWO caps each iwith own diode (opposite facing diodes)

[Lidmotor]

Very well done demonstration of this effect. 5 stars. I especially liked your comment above---- " But call it whatever I suppose, it is what it is."

[ray0energy]

5* you are not far to self power that thing :-)

just a good big flywheel and same more coils.

by the way Bedini is only using 1 trigger coil and the rest are slave motor coils. so no separate generator coils. Bill Muller work like this on his NEOGEN. only 5 coil of 15 coils ware to run it

[johncarl43447]

did you think of this or is it something that has been done before ? This is a very smart idea. Great work !

[codygillespie]

No, its not my idea. I got it from doug konzen, and i believe he got it from bedini. Its just a different way to get a flyback effect.

Cody

[Objectivityiskey]

the reed switch could rob some of the power,but have you considered the voltage rating on the diode? try charging the cap again with a high voltage diode. thanks!

[codygillespie]

Your right, a better diode probably would help . I no longer have that setup so i cant test it with that, but any pulse motor could easily be modified to play with the effect. I find it funny some of the things i say in my vids : ) cant take them back once on tape. I was using a 1n4007 in the vid, but i usually prefer at least 1n5408 or better yet an ultrafast hv rectifier.

[LoneOarman]

Is the spike bemf or shorting (negative entrophy)?

[codygillespie]

the spike is a collapsing magnetic field or the flyback effect. I hear a lot of people use the term bemf for the effect too however the actual definition of bemf dosnt really describe the spike. But call it whatever i suppose, it is what it is : )

[LoneOarman]

Cody, Anytime that you short the hot to the ground (reed), you get huge spikes. It's called negative entropy and it's not back emf, not collapsing field. Transistor biasing (to amplify) is similar. Dead short spark causes extreme amplification, huge spikes.

[TheTruthPusher]

Not just a renegade scientist ignoring "laws" established by corrupt men,

But this guy can actually direct a movie too! 5 stars!

[LoneOarman]

Watched video earlier on how Tesla was resonating against an already charged coil (wave peak). Reminds me of Leedskalnin's Perpetual Motion Holder Trick; as a precharged secondary coil: Heres the video: v=geYfUHh6nD8

[electrician725]

Cody!!! EUREKA!

I had been thinking of an Anti-Lenz radiant generator (no drag) that one could attach to a drive line of a hybrid car, and this video ties it all together for me. Solid State of course, reed switches would degrade too fast, but I got the eureka moment nonetheless. Thanks so much for sparking those neurons for me!

Rob

[codygillespie]

Well i would not say this is anti lenz. I would compare it more to a bedini motor. I was getting good results by adding the right amount of capacitance at the right frequency, many variables to play with. I would recommend searching thane c heins. Thats probally the generator you want.

thanks

[Daemo4]

I'm not very knowledgeable in the electronics field yet, but all of it really interests me. I came across another channel, ThaneCHeins, with a guy that seems like he's doing the same thing shown here. Correct me if I'm wrong:

watch?v=czXmazZ4obs

He's trying to get the message out to NASA, so apparently he thinks it's a huge deal.

But thanks to Cody for explaining things in simpler terms! You've got some great stuff going on here.

[codygillespie]

Yes, thane has some great work, im very impressed with his results. His system is different than mine in that he uses the full ac signal, i just use half wave. Also, the system i show here doesnt produce the great effects his does, but i do believe it could be advanced to do so, and have had some success with advanced versions of the shorted coil. Unfortunatly, i believe it has to get more complicated to get good results. Ill do my best to explain things in easy terms. thanks

[crackahcrackah]

If he's trying to get the message out to NASA then he doesn't really understand how things work. This has to be grassroots, bottom up driven. Relying on any one but ourselves is a mistake.

[0903390901]

EEEEE ?

[prototype9000]

i found out doing stuff like that is a good way to fry your volt meter without a shunt and smoothing capacitor. took me 3 volt meters to figure that out

[codygillespie]

haha, sorry to hear that. Got to watch that high voltage : )

[twilight1138]

Interesting. The spiking effect you described comes from the energy stored in the magnetic field inside the coil, which needs to find a way to be released when you cut the circuit. The circuit you built with the diode and capacitor is actually used in boost-type switch mode power supplies. Electricity is used instead of a magnet to induce the magnetic field, and the timings are set up carefully to generate the desired output voltage. Look up "boost converter" for more info.

[codygillespie]

Yes you are correct. Thank you, i will check out boost converters.

[javamark]

Nicely done...Tesla did lead to the car ignition system with the points, ignition coil, and of course the sparks plugs...and certainly this created thousands of volts from the counter emf effect....and the condenser not only saves the points (reed switch in your case) but increases the voltage across the spark gap.

This however...reviewing Tesla's patents was not "radiant energy". His radiant energy was collected with metal plates elevated in the sky...and connected to capacitors and ground.

[codygillespie]

javamark,

thanks for your comments. I know what you mean about teslas patent on radiant energy and this being different from that. But this is what its called by the group of people i am directing the video to. Check out Bedini motors if your interested in the theory of why they refer to it as radiant. energy.

[vietarc]

Good job cody, the quality of the vid is fine to me. The explaination is straight forward. Yes, when you hook the cap up, the spike will not show, but it will charge up to the max spike voltage as long as you have HV cap. The DTC position is zero, but the reason the neon light still lit is because it's close enough. If electric flow is momentum, radiant energy is kinetic energy . ;) "The spirit of Tesla will soon give it to the world as he has wished." This is just the beginning.

[zxrzxr00]

Can you achieve overunity with this?

[codygillespie]

Im not going to claim that, but i believe others believe that a modified version of this can. I have gotten this to be more efficient shorting it through a capacitor matched to the frequency of the motor. I will post that info when i get my motor going again.

[crippled82]

till now no-one dared to claim it :p

if the ou claims by bedini are false, it is a totally pointless system, don't you think?

[codygillespie]

yes, if its false then it would be pointless, but thats alright. I just like to play with this stuff and have learned a lot.

[electrician725]

Not so fast, hombre.

It is not pointless at all, Bedini has patents and a whole company selling battery chargers that really increase battery life and capacity. No need to have OU proven or dis-proven, the system works for SOMETHING useful and marketable!

I have proven the positive battery effects, I can charge and rejuvenate any battery style I have in the house, bar none. Certain high tech battery packs have protection diodes and such that need bypassed, but all have benefited from radiant ;)

[MrfixitRick]

Sometimes the simplest of experiments can produce insights to those who know how to look. It is in re-examining the basics that we will re-discover where ideas went off-rail in the past. And in picking up the threads that Tesla and others have left, we will leap into a newly powered, oil-less world soon.

[codygillespie]

Thanks MrfixitRick :)

And that will be a great day for everyone!

[weeeendog]

Cody, I wish you well in your pursuits, as I see they are sincere and noble. Sems that you will make it. I have my engineering degree, my patented inventions, and my career in medical diagnostics. Is satisfying.

thanks

Jaymz

[weeeendog]

Indeed there are many people working on more efficient motors, because the ubiquitous squirrel cage induction motor that runs industry is well known to be very wasteful. These motors are widespread simply because they are cheap to make. Better motors have been around from day one. Beating the common induction is not an impressive challenge.

[codygillespie]

I can see that we are just not going to see things completely eye to eye here, and thats ok.  I appreciate your interests and comments and i will keep them in mind : ) For the record i am currently pursuing a degree in engineering physics, and then plan to go for my phd in aerospace engineering. I have a profound interest in the future and the great things it holds in store for us all.

thank you

[weeeendog]

Why do you, and others, call this "radiant energy", or "radiant spike"? This is not a term used in physics as far as I know. Everything demonstrated and cited in videos here on youtube is well understood and can be qualified and mathematically quantified in classic physics. Why reinvent the terminology?

[codygillespie]

You are correct, it is understood in different terms today. I call it that to pay respects to the person who discovered it, the source of where current physics got their explanation from. Im not reinventing terminology, im using the original terminology. Like how we dont call capacitors condensers anymore. I understand your skepticism, as many people are crazy uneducated radicals. Its not to suggest that these things cant be explained, its to utilizing them for improved efficiency.

[codygillespie]

Thank you for being a respectful skeptic, many are very impolite. There are many trained engineers working in this field, and motors have been built that are more efficient than current models.  Google rotoverter for a shinning example. This motor runs on less power than the standard motor, and still preforms the same amount of work, and there is nothing magical about it, like you said , its all explainable. Its just been easier to manufacture and use less efficient motors.

[weeeendog]

You are talking about salvaging the energy of a collapsing field when turning off a motor. This is a small loss, hardly worth the bother. Surely you're not suggesting that there is some kind of fountain of free energy waiting to be tapped . . . for that would be chimerical thinking.  At best, you are chasing a fraction of 1% savings in putting this little spark back in your pocket.

Tell us of the lost mysteries of Tesla's coil!

[codygillespie]

I would suggest that you do some experiments to see what that "1%" actually is. There's no lost mystery about the tesla coil, its all in the patents, but the toys everyone builds today are designed different. The real version was for wireless power, not sparks. No, i have not seen a free energy fountain anywhere, but if you had a waterfall in your back yard... : ) If you really are interested, look it up. Who invented that AC power system your plugged into? He was no loon

[codygillespie]

Tesla stated that he was sorry he wasted so much of his time on his AC system after he discover "radiant energy". He spent 7 years researching it, and out of that came the radio, wireless power, and an understanding of improved efficiency. Most people have no idea how wireless power works. Yet it is accepted by everyone that its real. So to understand it, ask the man that invented it. Look it up : )

[weeeendog]

Coiling the wire simply concentrates a lot of magnetic field in a small space, thus exaggerating the effect. This same effect is well known for 100+ years to make hell on relay contacts connected to electric motors, mainly at the time when the motor is turned off. The arc damages the metal contacts. I suppose it is killing your reed switch!

Now I have a question. Why did Bedini call this a radiant spike? And what is Bedini claiming to have discovered?

Electricity is interesting.

Jaymz

[codygillespie]

You are correct, it does kill the contacts in motors and great lengths are taken to avoid it. However, to avoid it is wasting energy, it only destroys the contacts if you dont give it a path to go, such as charging a battery. Works like this: charge up coil, abrubtly turn off coil, direct collapsing magnetic field into battery thus conserving energy. Works best on resonant notes of coil. It was tesla who first discovered radiant energy, not bedini. But thats to much for me to cover here.

[weeeendog]

This spike is a well known effect, and is explainable. When electric current flows in the wire, a magnetic field develops around the wire. This is stored energy. When the circuit is broken (opening the reed) the current does not just stop immediately, it keeps flowing. The collapsing field induces a potential (voltage). You could say the current it trying hard to keep flowing, and may form a plasma ark where the circuit is broken. To be cont. . . .

[codygillespie]

You are also correct here about the collapsing field inducing a potential voltage. But when directed into a capacitor or battery, that potential voltage gets transformed back into current(amps). This is another well known effect (which was discovered by tesla). No ark occures when correctly set up. Tesla went way more in depth with this stuff but that info you wont find in mainstream science. Just like true wireless power, no schematics or diagrams in school books.

[codygillespie]

A motor is not needed at all to play with this, it is just providing a simple means of switching to get a pulse frequency, increasing the effect. The tesla coil as known today is not at all what tesla originaly invented, it has been changed and dosnt opperate as it should, its not just some spark generator. There is a lot of technology that has laid dormant for a long time but you will see it coming back soon.

[DadHav]

Hello, I might get it from my peers on this but, I think the magnet passing over the core and coil produces a standard sinusoidal wave, but maybe once there is energy in the coil the reed switch causes a sharp cutoff that gives a spike much like the transistor effect of a Bedini circuit. I've experienced similar with my stator motors running as a generator with the Bedini circuit working as though there was an input voltage to the motor, when not. See DadHav's videos some time. Nice work!

John

[codygillespie]

DavHav,

Thank you for your comment. Yes i believe you are correct. I have advanced this circuit a bit more and have a better understanding of it now. Its the same resonant interaction between capacitance and inductance just like a bedini, however in this case the power source is not the capacitor(battery for bedini's) its the inductor. Ill have to post some updated stuff when i get the time. Ill check out your videos.

[Drevtoobe]

knowledgemonger's explanation is correct. Just a few more comments: In your diagram you are listing the coil as having maximum voltage across it when the magnet is top dead center. The voltage is actually zero when the magnet is at TDC. It all goes back to Lenz' law, at TDC there is no changing magnetic flux through the coil.

Re, you debates: When a coil is open-circuited, there is no current going through it. However, there is measurable EMF across the coil if there is changing flux.

[Drevtoobe]

And about another on of your debates, Darkwizard is wrong when he states that he can get an extra "push" when the magnet goes away from the coil. It's simply impossible. Your test showing the rotor slowing down faster if the pick-up cols are shorted makes perfect sense. Some energy is lost to resistance when current circulates around the shorted coils. That energy comes from the rotor - i,e,; there is a slight extra drag on the rotor when the coils are shorted.

[Drevtoobe]

You make a mistaken assumption at the end of the clip when the capacitor is connected. You say, "We know it is putting out more than 20 volts because the neon proves that, etc."

This is not the case. You should study how inductors and capacitors really work. Most people on the forums have a general idea about how they work, but when you play with circuits you have to learn exactly how they work.

So when the coil is connected across the cap, there is no more high voltage spike, it's gone.

[Drevtoobe]

A coil's output voltage when it discharges it's stored energy is dependent on the load attached to the coil. When it's an open-circuit, you get a high voltage spike that breaks down the air and causes a spark. When it is a large capacitor, it starts off at zero volts and current, and ends at the cap voltage and no more current. A large cap my only go up by 0.1 volts.

It really is worth your while to tune out for one week and learn everything you can about caps and coils.

[Drevtoobe]

Correction of an ambiguous phrase:

"it starts off at zero volts and current, and ends at the cap voltage and no more current"

Should be: "it starts off at zero volts and the current flowing through the coil when the switch opened, and ends at the final cap voltage and no more current"

Each time the coil discharges into the cap, the cap voltage takes a 'step' up.

[codygillespie]

If you have any good sources, i would be happy to study them.

[codygillespie]

Hmm, well im not going to argue that studying would be a good idea. I will say that a higher voltage is still present with the cap connected, maybe not 90v or better but still higher, because the cap never gets that high without the circuit hooked up like that. I do know that you have to have a higher voltage than that of what you are charging in order to charge it higher. Ive got the cap up over 50V, the coil doesnt put out 50V conventionally. In other word 10V cant charge something to 50V

[codygillespie]

Actually, i would say its more than a slight drag, I did many tests to calculate the drag when shorting the coils, the video didnt cover any of that. My tests showed about 50% more drag than my control test, thats pretty significant. I have since then developed a way to get the effect without the drag, or the drag is the same as my control that is, but no increase or push like darkwizard suggests.

[frehleyukito]

Hi I'm Darkwizard your assumptions are right , i was wrong , i'm a simply person , that tries to get off Lenz Law, nothing more, now i'm trying to do the impossible , im triying to put in phase change of magnetic flux with voltage and current, or by pass this with energy balance.

[frehleyukito]

Will be interesting if we can join the forces and ideas. Thanks, Darkwizard.

[codygillespie]

Hi Darkwizard! Good to hear from you again. Im not sure what you think you were wrong about? There was a lot of talk on the forum, i dont remember it all. Im not sure im correct about this either my friend. I just post what i see, right or wrong. Yes im still interested in working together on this, but my motor really needs some work so i can really play with this. May be a while : ( Have you discovered anything new?

[frehleyukito]

I was wrong, the voltage at tdc is 0 volts, and my switching device will not work, because the current starts to flow before the magnet is inside the coil, and this creates opposition to the north pole magnet.

[frehleyukito]

What i am trying to do is remove the statement that says, the current generated opposes the magnet repels it and causes drag.

[frehleyukito]

That is the gate to OU in my personal ideas.

[codygillespie]

I have ideas that are wrong all the time : ) Bad ideas make for good learning experiences : )

[codygillespie]

Wow, you posted a lot here! Ill try and respond to most of them. First off, thank you for your comments. You are correct about the voltage actually being zero at tdc. I started off assuming what was happening on the thread was correct, i have since learned some things, so all and all i think it was worth it. I may change the video, or make another one further explaining it.

[crob227]

how would you appliea mosfet to this system?

i have used small reed switches from radioshack that has a coil built around a magnetic switch, so youcan iether pulse current through the coil to trigger or use a magnet..... also i found a relay in a old air conditioner unit thats coil has hair like wire in it and gets 80volts with 1"x3/4 neo's

[codygillespie]

crob227,

Im happy to see some people are aware of this. Please note, im not claiming this to be an efficient way to generate power and i have done no testing of efficiency compared to regular power generation. There is however people claiming they have advanced this technique to where it puts no load on a motor. Follow the thread i provided in the(more info) if you are interested. In the thread you will find your mosfet awnser, patmacs circuit.

[knowledgemonger]

I will butt in here with a bit about the MOSFET.

You need a high voltage N channel MOSFET, a source of about 12V, a resistor, and a reed switch that closes when you want the MOSFET to open.

A resistor (10K) can pull the gate of the MOSFET up to 12V turning it on.  The reed switch will short the source and gate suddenly turning it off.

If you dont want to use a battery for the 12V another coil, diode and capacitor can make a generator for you.

[carlosman79]

Good work cody, is good see it in good quality video, I hope to buy a new video camera sooner. Maybe I could avoid complications

patmac.

[codygillespie]

Patmac,

Thank you. I dont own a good camera either, the one i use is my parents. Hopefully we can get a good video of your circuit working and some measurements. If i get the parts for your circuit and get it to work, ill be happy to make a video for you.

[knowledgemonger]

Devices like this make high voltages but aren't very efficient. It is not the sort of thing you would want to use to charge a battery. It however does light up a neon bulb.

If you build a very good one, you can pulse light a fluorescent tube. This makes a strobe light that will make the rotating machine appear stopped.

[codygillespie]

Knowledgemonger,

thanks for the reply. Im not claiming this to be a efficient way of generating power. I did this video to explain the basic concept of it creating a HV spike for a forum i post on. The threads main focus is on two peoples claims that they are using an advanced circuit of these basic principles and are getting these spikes without showing a load on the motor, which would be very efficient.  Im not claiming this to be true or not true, follow the link i provided if interested.

[knowledgemonger]

My comments to aimed more at the others that may watch the video than at you. I explained what caused the voltage spike because I got the impression that you hadn't yet figured it out.

It is interesting that a system much like you have made can produce 20KV when turned at only a few RPM.

Since there isn't much energy actually produced the drag caused will be hard to measure. You need very good bearings to reduce the friction to a very small amount to make such a measurement.

[codygillespie]

Thank you for your explanation, your right, i didnt understand. Ill be the first to admit that i dont understand half of the things i do. But the more things i do, the more i learn. Thank you for your help.

[knowledgemonger]

This is the same basic idea as is used in the ignition system of a lawn mower.

The trick is the short circuit allows a current to build up in the coil. The magnet going by causes a changing magnetic field so the "lines of force" are cutting through the coil windings. This causes a current to flow in the coil that according to Lens's law opposes the change. When the contacts open, this induced current stops suddenly. This means that the windings see a very rapid change in flux.
