Twin Tesla Coils - World's Largest

[eltucumano28]

so manny use's for this tecnology oh god!

[blowupuate13]

THIS IS THE ULTIMATE ZOMBIE APOCALYPSE HOME DEFENSE WEAPON!!!!!!

[Serostern]

"Twin" coils?

They aren't even properly tuned or synced.

[mikalshort]

aww, i wanted to see them connect for a while... not just for a moment..

[L0lzer0]

When i was 10 i went to a summer camp we played with tesla coils it was fun! :D

[rocketman221projects]

I could use these in my yard to get rid of the damn bugs.

[theBRENNOGUITAR]

Tesla was The Big Cientist of history!

[rikimaru6811]

Swarm leader: Do NOT cross

[supermohamed76]

wow the lightning of both coils touches woooow if I could click the "like" button more then one time I would do it

[King19840805]

And now, ladies and gentlemen, welcome AC DC with their favourite song "thunderstruck"!

That would be a quite nice concert though ^^

[JakeAmick]

We should harness the electric power of lighting those bolts would power us for years since they are 100time bigger

[checksummedchest]

True Free energy devices exist,But some very powerfull ppl don't want you and me to be free from energy costs,Go to LT-MAGNET-MOTORdotCOM and get the blueprints for a genuine magnet motor ,Let the revolution begin!

[Hazardass88]

This is 5 million volts.

An average lightning bolt has 1 BILLION volts.

[electicalfanatic]

they were the worlds largest...

[RonnieRambin]

This is the key in creating the flux capacitor!

[shmackahippie]

Curious how the video subtitles "480 volts of 3 phase AC" ... A Tesla coil is a single-phase, high fq transformer :)

[thewii552]

@shmackahippie that is the input to the step-up

[shmackahippie]

@thewii552 Why would the step-up transformer be 3 phase? I assume it is 480vac split/single phase? The coil itself is a single transformer, generating a high frequency, high voltage, single phase.

[thewii552]

@shmackahippie i am not sure. only that way would make sure is what I said. Unless the guy is saying that each coil is one phase (when running out of phase) and the primary step-up is one phase...it really doesn't make sense...

[FudgeButters]

show that to zeus and see what he thinks

[MrCrazyDaniel]

@FudgeButters he'd be jealous

[Kdidly666]

If you had a phone that was on, it would fry if you were even remotly close to one of these.

[TCzelusniak]

would you disentgrate when you touch the stream of blue death?

[ItsTheAlfred]

@TCzelusniak nothing would happen, because whilst the voltage is very high, the current is very low, so it would be like a static shock

[HemelDevin]

i wonder what would happen if they did that in the sky directed to the ground in a thunderstorm or on the ground when connected to the mains ..

[KingHarkinian]

WOOSH! a hole between dimensions! xD

[ogschizo]

Grow some balls and put it on DC!lol

[shmackahippie]

@ogschizo lol, real men use DC

[777EZekiel]

this is electrolove!

[silverbird58]

Now step up the freq

[zker666]

wow lucky chore for whoever wound those secondaries...

[16SKB]

wonder what would happen to a bird that flew between them...

[gammaworld]

The Aliens?

[thomasfohr]

its like red alert the game

[CosmicGnarler]

the coils are hi-5ing each other

[zimtower]

That has to be flippen loud, most of that energy is being converted into soundwaves.

[roderik1990]

and remember kids:

don't cross the streams

[je641687]

Funny you should post that. I'm watching Ghostbusters as we speak!!

[adamz1988]

@roderik1990 even if we have a hftc??

[2010Barbon]

@roderik1990 I wanna get a couple of these things at the front of my house to keep out the tax collectors.

[mikalshort]

@roderik1990 Who you gonna call?

[crazymike65]

so if i were to run through the tesla coils, would i attract the electric thingies, or would they keep hitting random places?

[moldo2]

How lightning and sparks act, cut down to basic: The readon of an arc is becouse of too much voltage in on one of the poles. When the level of electricity reaches this level, it breaks the density of the air surrounding it, causing an arc. The arc allways travel towards the opposite pole(+ --> - and - --> +) So therefore if you were to run trough the space between the tesla coil's, you'll be toast

[JoelThedude4u]

the ceond you get withign range they will hit you until you get far away. and once they hit you you will have a hole in your flesh where it hit you and one where it went to ground. But because this is continius, not like ligthing which is once, you would probably keep shocking until you fry to death.

[crazymike65]

eeek, now i see why the camera guy is so far away.

[Pujc]

Ahh de ott lettem volna ..ahh I wish I would be there ..

[dmoney0015]

i wonder what aliens think when they visit us from outer space and see this....

[joelito101]

they probably think," don't cut the red wire"

[Nec0byte]

Alien Mother would say: "At this age, they always like to play with matches" =P

[AlexandrusMegus]

Tesla vs Aliens...guess who wins? :)

[davis1000000]

They think we were doing that 10 million years ago

[ETBRAIN]

Big, Bold and Beautiful! A "Current" 5 star video!

[Luciferdesrea]

I have one thing to say about seeing this. Use Tesla Coils to electrocute people. Like in Red Alert :D

[mongorians22]

:D i LOVE THAT GAME!

[flob2366]

yes, good game

[mcliars]

@Luciferdesrea Actually, a TC can't kill you by electrocution. Since it's high frequency, the power flows on the surface of your skin and not thru it. It might still burn you to death though,

[haloamusedcrib]

@Luciferdesrea real Tesla coils don't hurt you they use frequencies over 2000 and you home electricity uses a frequencies of 60.

[Numb4223]

Wow.....Get them a bit closer and thats one hell of a Jacobs Ladder!

[metalini]

i dont get why the voltage potential doubles when theyre put at 180 degrees out of phase.

[PorkchopsandwichGI]

because they are oppositely charged when they are out of phase like that.

[mniles74]

Basically, it's the electrical equivalent of 2 cars heading toward each other at 55 mph, the relative velocity of one car to the other is 110 mph. Same concept, but with voltage instead of velocity.

[Golgiapparati]

funny!

[Xxero0]

they should put a bunch of those on the moon!!!

it will transmit energy to us, therefore we dont have to spend gas money!!!

and then we will have money for better things!!!

like pudding!!!

[Matrex50]

YAY PUDDING!

[TarantoRemixRecords]

i love pies though...do pies count?

[Xxero0]

pies are good, too...

[lionelatwill]

What amazes me most about this video is all the people trying to take photos with a flash.

[dummy1977]

Next time someone tells me about how they are "going green", I'm going to slap them, yes..but then I'm going to put one of these #@%@#Q$kers on my front lawn. Wait..that'd be crazy.. TWO of these #@%@#Q$kers on my front lawn. I'm pretty sure my insurance will cover it.

[XelifZepol]

Excellent Tesla Coil video. However, Tesla himeself in his patent felt that the discharging of sparks of his Tesla Coils were very inefficient in the transmission of wireless energy. Therefore, in his patent he devised a more efficient method. He also recommended frequency of 230,000 to 250,000 cycles at high voltage and use air as a medium at elevations of 15,000 feet or greater.

[Kataze]

but would that look NEARLY as cool? Come on, Tesla.

[XelifZepol]

Kataze, not as cool looking. But remember that Tesla's vision was to provide for the wireless transmission of electricity. He realized the "spark" generated by his Tesla coil was lost energy. In his newer patent he thus refined his Tesla coil and that is what most people miss now when they build his Tesla coil.

[Kataze]

I think it's energy well spent.

But seriously, Yeah, I know about what he was really trying for. But for many, that's not what really appeals to them about the Tesla coil. Anyhow, it was more of a joke than anything else.

[XelifZepol]

As a continuation of my last reply, Tesla rightly surmised that his spark was a loss of energy. So we puny humans stare at the spark from the older version of the Tesla coil. But Tesla himself patented a new version with refinements and therefore no spark at all. Tesla's plan was to transmit as much as he could through the natural conductivity of the air at a pre-determine frequency. He discovered air is the best conductor at so many kilobars of pressure!

[bearshaman0]

now thats a home security system !!! put one of those on the four corners of your property with motion detectors, :)

[MachineAgeVictim]

Wow, Tesla sounds much better on their album, was there an equipment failier? were their amps not plugged in??

j/k ;)

[bimm3er]

hey you make that thing play music, I'll pay good money to watch that concert!

[jrngln]

A tesla coil can play music

[Cthrilla]

Bimm3er is my other account, I mean play good music and go on tour doing popular covers. That is what people would pay to experience. On this video it's just noise not cool we want more mario songs and 80's beats.

[lHorusl]

I thought the largest coils are in the Boston Museum of science...the ones Tesla made himself....

[mclange]

.....and not a bug in sight.

[srussert28]

I bet Tesla was smiling down on that display.

[CookieJew]

damn. that would be awesome to be there..

[ttsmoke]

suck to get hit by on of those

[jamestigris]

Actually no, while the voltage of a Tesla coil is super high, the amperage falls super low creating generally safe wattages (Watts=Amperage*Voltage). Granted, on a Tesla coil of this magnitude, it may not be that good for you after all.

[justinmcburney]

ya wouldnt even notice lol

[rcman50166]

well actually the peak amperage by one of those things would give you severe burns. It has to be runnig close to 10000 watts, probably more. I would guess the voltage close to 2 million volts. Do the math and it would be close to 5 milliamp peak, 16 is enogh to kill so 5 would be extrodinarily painful. All of course guesswork.

[Fetus133]

It is the Voltage that does the burning(electrocautery), Current affects your central nervous system. It says in the video, 'Estimated 5 million volts,' and other sources say they run at 108kVA.

[Persekarva]

Which gives 21.6 mA.

[alanwolstenholme]

so if we doubled the voltage again and halved the current apparently not enough to kill we can survive all those watts! all that heat-im missing something here-the energy is still there- i think it is the power going through the heart that kills....????

[Calliber50]

Well, not only do tesla coils increase the voltage, they also increase the frequency. You get what they call the "skin effect". The high frequency doesn't let the current pass through the skin. It rides on the surface. Hard to believe and I'm certainly not going to test this theory on myself. However, Telsa himself didn't die from electrocution. I'm sure the x-rays and and microwaves didn't help him though!

[alanwolstenholme]

k. perhaps that's why people survive a charge from lightning, 1000+ amps/volts. i suppose it's path isn't intended to go through a mere human but the bigger earth. perhaps it is coinsidence that a strike hits someone, just in the same path as it's targrt. i could imagine massive injuries or death resulting from the flash but not cooking him from the electrical charge. this dosn't help me on my quest to find out if it is the overall power that stop the heart or current.

[alanwolstenholme]

basing it on the theory 20m ma ac can stop the heart i can't get to grips that if 10m volts were past through a human, where only one ma current was present, thus making 10k watts of power-enough to heat an electric shower! how can this not stop the heart! or if is doesn't, would it cook the person quite quickly as i would expect? magine this poor guy is rigged into the circuit so that all the electricity passes through him and not arc to earth.

[alanwolstenholme]

perhaps it is just the fact that it only takes a small amount of ac current to fibulatethe heart-perhaps the muscle can stand higher power/voltage creating heat and iminent failure over time but not 20 ma of current?

[alanwolstenholme]

and back to the subject of tesla coils! why does the frequency have to be so high? what would happen if the frequency was much lower but with the same current/voltage?

[Calliber50]

Lightening is DC power. Current flows one direction in a lightening strike. Tesla used high frequency in his coils because he wanted to transmit power over long distances. He wasn't trying to produce lightening! The discharge into the air was a side effect which he didn't like. You can produce the same voltages by hooking a transformer up to an outlet in your house. However, as you increase the voltage your current will decrease.

[Calliber50]

So a 120 Volt 20 amp outlet will only produce a little less than 2 amps at 1200 volts. Now I've shocked myself with 120 volts ac and 50,000 volts dc. Why am I not dead. Well the 120 volt shocks occurred when my body resistance was normal. I wasn't wet and my body wasn't sufficiently grounded. If my body's resistance was low enough the 20 amp circuit could have provided enough current to kill me.

[Calliber50]

Now the 50,000 volt accident occurred when I was playing with my High voltage DC power supply. A free wire came loose and the potential difference was enough to statically attract the wire to my hand. So the wire jumped and grabbed me. My body resistance was normal, but that doesn't matter at that voltage. Because electricity can jump several inches to ground. However, my DC power supply can only give 5mA of current continuously. So it shorted out.

[Calliber50]

I work on medium voltage equipment. Medium voltage accounts for AC circuits 1000 to 35000 volts. A recent circuit I worked on was 4160 Volts rated for 4000 amps continuous. Now lets think about what would happen if I grabbed the live circuit. Instantly I would be part of the circuit. My shoes are rated for 500 volts. So the voltage potential across me and ground would be 3600 volts. My bodies resistance when dry is 100Kohms. However, If I sweat it's only 1000 ohms.

[Calliber50]

So best case scenario there's 36 mA flowing through me. Worst case there's 3.6 amps flowing through me. Now comes the fun. If the electricity hasn't effected my muscle control I can break free from the circuit. If it is too strong I become stuck. So at 3.6 amps my flesh begins to cook a little in spots. Burnt flesh conducts even better. My body resistance drops, more amperage equals more burning. I just literally cook on the circuit.

[Calliber50]

If any of that current passes through my heart be it .03 amps or 3.6 amps my heart has probably stopped. But my brain is still active and I can feel pain for several minutes with my heart stopped. By the time 4000 amps is achieved my body is burning. So there are many factors in electrocution. Your body resistance, circuit power ratings, voltages present, and how long you're part of the circuit.

[Calliber50]

So bottom line, playing with Tesla coils can be fun and give dramatic displays. People often charge themselves up with them and shoot sparks from their finger tips. However, all it takes is one mistake. They become the path from the secondary coil to ground!

[alanwolstenholme]

yes i know lighteningf was a bit 'off topic' and i wasn't confusing it with tesla-yes and i know aqbout his goal to acheave wireless electreicity. also know there are many factors that could change the way electricty conducts through your body-resistance,ac/dc,groundin­g,max current over time ect. i am trying to find an answer putrting all theswe aside. best case scenario. so lets say it's dc, conductors implanted inside flesh over a large area at oppositte ends of the body, circuit capable of

[alanwolstenholme]

producing current without shorting the circuit! 2 similar weight/type people with the same hook up (they must have been bad!) 1 has to endure a constant 1 amp at 10,000 volts (10kw) the other 100 amp at 100 volts (10kw) any conbination you like. we could do 1 ma at 10 ma at 1,000,000 volts but this would bring about a discussion on arcing accross air etc which would divert my question again. questions are is it current or wattage that causes the heating in the body without resistance etc?

[alanwolstenholme]

would the pain feel the same? other question on a similar topic is can 1 ma (limited, perhaps some kind of stun gun) at say 100,000 volts, lock the muscles so they couldn't let go? how would this be a different shocking experience at 1000 volts at 100 ma? the body is soaked by the way and buried well into the flesh in the second instance!

[Calliber50]

Well the current would cause the damage. So the more current the more electrons flowing through a given area and the hotter something gets. It wouldn't matter if the person is soaked or not in this example since you've now bypassed the resistive skin and gone directly into the flesh and blood. The only problem with your experiment is it's impossible. Resistance determines amperage for a given voltage (or voltage for a given amperage).

[Calliber50]

Voltage = Current * Resistance

Power = Current * Voltage

We unfortunately do not have a means of building a power supply which controls current and voltage at the same time.

[alanwolstenholme]

so both experiments have the same wattage passing through the body, one high voltage/low current and the other vice vera, but only the one with the high current would cause the damage, is that correct? it's just that i have heaqrd it mentioned thaqt it's the overall power or wattage that does the damage... so apart from people dying of shock(heart attack type) you could say that at about 5 ma ac current any voltage could carry this charge, 1000's of watts passing through but it wouldn't kill?

[Calliber50]

Like I said, your experiment is impossible. If both subjects have the same resistance then the more voltage you put the more current. So if current and voltage both increase the wattage increases. So technically yes, wattage kills, but it's the current not the voltage that will cause the damage. Moving electrons generate heat. They bump into things and they create magnetic fields. If there are more electrons from an outside source then your brain the body can't decipher signals from noise.

[alanwolstenholme]

my word there always seems to be a catch! i know the current draw is proportional to the resistance. should have mentioned current limiters or controlled current/voltage. im just trying to see a comparison using humans as a test subject. could we try the experiment using a controlled max current and voltage with the same values then?

[Calliber50]

Current limiting works in two ways. One, you lower the voltage to get the desired current. Two, you turn the power supply on and off a certain percentage of time. So if the current will reach 500 amps at 100 volts you only power it up 1/5 of a duration of time to achieve an average current of 100 amps. This is a PWM circuit and it still wouldn't be the effect you desired.

[alanwolstenholme]

set them both to 1/5th duration then. a car headlamp at 100 watts draws 8 amps and 240 volt mains 0.4 amps, both the same output power from both high and low current. surley a small transformer with the secondary coil giving 1000's of volts might only have a very small current output-perhaps it could be limited like this. so lets try the experiment with the subject having the same power going through him using whatever measures necessary tohypothetically sumise what the effects would be.

[TremblayCT2]

That would be something amazing to see for real... wish I was there, music ain't bad either.
