Before you touch your pint, check carefully, very carefully, for tell tale signs of oily film. grease-proof paper and kitchen foil in or around the glass. Or your pint could be his home made capacitor and you could be his fuse, 😊😊😊
@@ianbrunskill6787 Laugh my my fucking ass off has the same energy as that video that's like "Oh yeah, Land of the free? Then why can't I dip *my my* balls in the burger king soda dispenser"
Just one correction to make: The breaking capacity of the fuse is NOT the current at which the fuse will rupture. The fuse that you destroyed which had a breaking capacity of 82kA - it has the ability to interrupt ("break" ) a surge of 82kA - you probably destroyed it with a couple of thousand amps. Why "breaking capacity" is important - if your 50 amp fuse blows but the circuit supplying the current has the energy and low source resistance the gap left by the fuse can sustain an arc and a huge fault current can continue to flow - which is bad. (fires can start if that fault current continues to flow ) So in high energy circuits you have a fuse which is rated to "break" that high energy High current arc/ fault current. Here endeth the lesson.
You sound like a Brit, the slowmo guys here on YT are Brits and they are really good at it! Please ask them if they want to team up for something just like this would be so amazing :D
+DerZocker2000000 400MW for a very short period of time. Watts are the rate of energy and have no time component. So say a typical house has on the order of 200V x 200A, that is 40kW. Also let's say that the 400MW lasts for 0.001 second. 400MW/1000 = 0.4MW = 400kW for one second to charge up for that release. That is still 10x what a typical house might have for service from the power company. But it took him a couple seconds to charge the capacitor. Also my 0.001 second number was pulled out of thin air so you could easily say that is 0.0001 to make the numbers work out. Even 0.00001 seconds seems plausible, which would be only 4000 watts for one second to charge.
+Aaron Axvig I dont mean to be rude or contradictory. I agree Your overarching idea is correct, surges of high current and voltage for very short periods of time can be handled by the system even if it goes way over what it is rated for long periods. But the dimensional analysis of the watt is a joule per second (joule being a unit of energy) so time is indeed a component. You even used the word rate which implies time is a factor. Energy per time is = power (watts), basically how much energy is dissipated in a second. When you multiply watts by time the time cancels out and your left with joules or the more commonly used watt hours. In either case your left with just how much energy that system delivered in that time frame. So all that math that was shown making .4MW to 400KW really isn't accurate. But regardless you were right in answering the question that the short period of time makes it possible. Just wanted to clarify on the whole power energy watts part of your comment
u r correct, jouls are the correct term that doesnt have a time component, or in other words watt-seconds (yes the term for timeless units of energy has the word seconds in it, but it makes sense because once the time and power are combined together into one term it becomes *total energy* which is timeless)
"80 thousand amps. Yeah I'm happy with that." Awesome line :) Am I right in thinking you had at least 320 million watts of power (4,000 * 80,000) ? That's.. startling, frankly.
How is that possible? I get have u can get 500kv and little to no amps. but having both insane amps and volts? How can he pull all that power from the wall in 5sec? A powerplant barely outputs that:p would love a explanation. cus I must be missing something out ^^
I'm no expert myself, but I am pretty sure it's because of the capacitor. The capacitor is storing energy over a period of time (we saw at the beginning of the video that he charged it up over a couple of seconds) then releasing it all in one super fast pulse. It's basically like a battery I guess - you charge a battery slowly (eg at 1A - 10A rate), but then some batteries can be discharged at up to 100s of amps (eg car batteries can do many hundreds of amps.) In the case of this cap, apparently it can release more than 80kA :)
the 80kA rating on the fuse is the amount of current the fuse can safely break without then the risk of it welding together and carrying on conducting ! 320MW noway dude lol! The capacitor could be rated at, say- 4kV and 32mircoF- so check out formulas Q=CV (charge in coloumbs= capacitance in farads x voltage across cap in volts) & W=1/2C.V² (energy in joules= half x capacitance in farads x voltage across capacitor in volts squared!) ... so for energy at 4kV on 32mircoF cap - 1280 joules ! Whoop! ... i put a short on a electrolytic 1500mircoF cap at 200VDC - fuck, i knew it would bang, but it was loud as fuck!! ...calculated at 30j! wtf! Bet Photons was well loud!
TheBloke here's a idea if you want to try that...try REAL HARD to rent a apartment right next to some high tension power lines (the really BIG ones on those big metal poles)...then run a LOT of cable (as big as you can find) right under those high voltage lines...then make your own video of what happens when you suck lots of power away from those high voltage lines...?? ;)
My 100kv PSU is a sweet thing as well. It pulls an 8.5 foot and runs off a power supply that steps 120 vac RMS to 380 vac RMS (big transformers used like in his vids). I feel happy that I finally can have some crazy stuff like him. Then the 200 mv power supply at over 1000 amps continuous.
Hi, was writing to see what your capacitor was, thought I must've missed it. But then I saw nearer the end, 138uF at 4,500V - so that's a hair under 1,400 Joules. I have a couple of 5uF 25kV dc in the shed, & have always wanted to do this sort of thing, when I have the space & time. My 2 total 3,125 J, but I figure I'll give them about 30kV (They're VERY robust caps) for 4.5kJ max. They are rated for Pulse discharge application & very low inductance - i.e. very high current. They came from a H.V. test facility at a University. There were 16 available at the time, but 2 was all I could fit in my car boot on the day. When I came back for more, they'd gone :-( But I just wanted to know what energy you were using for the can crusher, etc. & now I know. So I have plenty :-)
**Holy Crap** That capacitor 'discharge' test made a hell of a pop/snap! Good GOD I wouldn't want to accidentally hit the terminals with any part of me..One of the best, to me, is the 300kv On A Television! 57 Channels and something on lol
+joey lapoo It's called being British. It's the same language used in America but sounds different. It's referred to as having an accent. There are places in the world where they don't even speak English! Wow, crazy right!?
To photon for your biggest fan... PLEAS!!! Pick up the channel again I miss seeing your vids I understand the bullshit you are going through but please promise me one-day... You will pick the chanle back up again my man please. Your biggest fan Ian B
In testing the MOT's you said you were going to "change it into DC and stuff it into the capacitor." I'm curious as to how you would do that since I would have thought you would need to rectify and smooth the 4kv output from the MOT's which would require some additional heavyweight components. Also, wouldn't the converted DC exceed the 5kv rating of your capacitor?
Here's what I don't get, the globe on a Van de Graaf generator acts like a capacitor right? Why is it that you can store up 200 kV on it and while it might sting for a second, it doesn't do any real damage because the voltage drops off so quickly; but your capacitor which only is charged up with 4 only kV can make a potato explode. It's not connected to a source of voltage anymore, so how does it sustain high voltage long enough to harm someone?
The electric charge in this capacitor is much much higher than in a Van de Graaf generator (note that electric charge is measured in Coulomb and is unaffected by the voltage). The voltage is not defining the "dangerousness" of an electric discharge. For instance a discharge of 100kV and 1C is more dangerous than 200kV 0.5C. There has to be enough voltage to let the current flow (you can touch a power source with 0.1V and 10000A without getting hurt), but if there's already enough, there is no profit of using more voltage.
Der Kuchen Suppose you let an ordinary Van de Graaf generator charge up this capacitor for awhile. Could it build up a lethal charge? If you made a Van de Graaf generator with thicker metal and better insulated from any ground could you build up enough energy to explode a potato the way that this capacitor did?
Travis Gibby Any HV source *will* get dangerous when combined with a high enough capacity capacitor. To get a powerful discharge from a Van de Graaf generator, the sphere probably needs to be massive, but my knowledge of EHV isn't high enough to estimate this correctly
Depends on the "size" of the capacitor in terms of Farads of electrons it can hold. I haven't looked at a Van de Graaf, but I imagine it is constantly leaking its charge to the environment or to the other side of the generator, thus never storing enough Farads to do serious damage.
Ace Frahm Just a little note to prevent the spread of wrong information: Farad measures how many electrons (in Coulomb) are stored per Volt. The capacity (Farads) is static in this case. :)
put a quarter in the middle of a coil and connect the cap. to that! theres a few guys north of me in Seattle that made a video of squishing quarters with capacitors
The best video to date by far that I have seen from you, and I have watched loads of vids (The funniest being the washing machine with a brick thrown in).... 80KA WTF? Look at the beer can after the mega abuse and I think you can see the Flux lines in the deformed (Destroyed) Can. I admire your bottle to work with such energy producing equipment, Have you got a degree or two in this field or are you winging it LOL. I doubt you're winging it as you have produced a fine piece of power control equipment. (Love this and the way you present it)
Lopiklop Not anyone. There are common medications like serotonin reuptake inhibitors that typically greatly increase the effects of alcohol. Someone who needs to take 40mg of fluoxetine every day probably wouldn't be able to do much of anything safely other than sitting after a drink.
would a 4kv 9400uf cap bank be very nice? im making one but it would be nice to have a 5kv volt meter instead of having to measure of one cap 400v each... any ideas of where I would get one?
Shortly after this video was made, the capacitors were installed in an Apple iPhone 6 Plus (RIP Stephen Jobs). Battery still only lasts half a day though! If you would like to debate me, head on over to /r/android. But be warned. I'm a Reddit power-user. Have a nice day!
With the exploding 80KA fuses, even if you did not get 80k discharge current the fuse would probably rupture anyway as you have several KV DC on it, the sand is not quenching the arc as the voltage is too high, causing a prolonged arc in side the capsule and exploding it. So the fact that it exploded does necessarily mean you have more than 80KA fault current. You could prove it too, by placing a 0.1ohm resistance in series to limit the current to say 50K, use a long heavy cable as the resistor or make it out of thick stainless wire.
oi! i got a statement and a question, 1 looks like you have a lab of a mad scientist! 2 is it possible to pop a safe using an intensified version of this?
Tell us about your really slick control panel. The meters are unlabeled. Is it a 300 V, 20 Amp variable supply? Are you really generating all your HV w/ Microwave transformers? Where'd you get that control panel? Looks quite professional. Also, is that a Maxwell HV capacitor? 100 uF 10 kV? Maybe you can do a vid on your rig. Really fun stuff! It is good that you point out that what you do is lethal (though that should be obvious from what happens to the objects under test!)
Hey, Quick question, I ask because I dont know. If you attached the big boy supply as you have, switch it on charge the cap till the current is 0 leave it on and then discharge the cap. Would you get a standing ark because the supply is on or would you be able to get rapid fire discharging bangs one after another? Thanks Dave
Its a bit of an old video of his, but I seem to recall this might've happened when he was playing with lasers and aiming them at the camera. And this was a visible light type laser, 3W range I think? maybe more I dunno. Anyway I'm pretty sure he would've broken some parts in the camera either way with or without a filter. Besides its photonicinduction it wouldn't be right to protect equipment too properly.
Actually, they are from shining a powerful laser straight into the camera. I'm pretty sure an UV filter is not going to help against such a powerful and focused ray of light. I'm not really sure if it has anything to do with over-exposure in this case, because the laser he used is so powerful it burns stuff.
Damn, that capacitor.........it can't be bought in a corner deli I suppose (and man, you must be loaded if you can afford such incredibly expensive gear like that capacitor, HV transformer, that big power supply thingy you used etc.). The can crushing experiment is rather neat. I wonder if a can crusher can be made using some smaller capacitors too (or a coil or something that's MUCH cheaper than that capacitive monstrosity)....
I'm on board with this sort of experimental, because I can nutty stuff but... That light bulb didn't seem like a good idea. I have to imagine there was so much shattered glass apread around the room that short of ripping up the carpet you'd never get rid of it. Cant get the idea outta my head of you tracking some out on shoes and then catching it in the kitchen barefoot :)
I still prefer the way I wired the MOT's up to charge the cap. He thought the way I wired them up was dangerous due to the cap not being grounded. When he popped round one time he saw how I wired them up n didn't think it was safe. I use 2 old school MOT's (which he was extremely jealous of) and I centre tapped the output, so both sides of the cap were 2250v from ground, where as he made sure that it was grounded. Personally (and I still haven't changed my mind about this), I didn't think the way he wired them up was safe. Having a 4.5kv output next to a 240v primary coil and the chassis being live to the max output voltage of 4.5kv. That's why I wired them up the way I did and having some old MOT's really helped as they were much more durable back then 🙂 I personally thought it was much safer and they were being run the way they were supposed to be. Anyway The way I made sure it was isolated from anything was by sitting it on an old turntable cover, which must of been around 5mm thick PC. Also, the second I used it, I shorted it out n kept it shorted the entire time I wasn't using it, like photon did. Safety first 🙂👍🏻 Anyone who knows a thing or two when it comes to caps, is that you should ALWAYS KEEP THEM SHORTED!!! Especially when doing stupid shit like this. If you quickly short the cap out (that's what this video is about), it will charge itself back up close to the input voltage. This will dissipate over time but that all depends on the type of cap, input voltage, it's capacitance, ESR, temperature, etc. Some caps like these, if you charged then up n just left it, that stored up energy is enough to kill you many many months down the line. Even tiny caps that you can hold in your hand are lethal! Just because you're watching a couple of RU-vid videos n think you know a bit, doesn't mean your component enough to carry out works on mains voltage and HV. A little knowledge is extremely dangerous! STOP!!✋🏻🛑 If you go on my channel you'll see how much fun I had with that cap lol. Photon popped round one time n I said he could have it back as I was moving house (which is a very long story but I'm not going there) as it was one less thing to move as it's very heavy and I'm not quite as able as I use to be. When he took it back n use it again he said that it was MUCH more powerful after I had it but I'm not sure why tbh 🤔 The trannys I was using were from the 70's n maybe the output was higher back then or something but he DEFINITELY said it was twice as loud n much more powerful. Thinking about it, I wish I'd of kept it 😕 On a different note. A while ago, I use a 10A intermediate switch on the primary so I can have over 2,250V to ground with double the current or 4.5kv center tapped like I use to charge this cap up. It gave me a bit more options 🙂
Also I got a question how is it that your electrical subpanel in the house as well as the wiring outside of your house and the transformers in your neighborhood don’t have a heart attack when you do these kind of experiments pulling in so much wattage and amperage?
