Mehdi. I want to tell you a positive story about your influence: Yesterday I was unfortunate to have a little accident hile working on a compressor. I was replacing a emergency shut off switch. The breaker to the machine was turned off by myself. But as I was working, some asshole came by and decided to turn it back on because...reasons. So I got a full 400V charge through my upper body through both arms for around 1-2 seconds as my muscles locked up. I just remember screaming my lungs out in pain. After this we called an ambulance, went to hospital, did check-up etc. But what made calm about the pain and hyperventilation I was experiencing, was me thinking: "Calm down, Mehdi does this all the time and he's fine and dandy. It probably looked funny." Even though I know 400V is not a joke, your videos was the first thing that popped into my head, and it kept me calm and turned it into something funny. Thank you Mehdi for making fun and educational videos. It really helped me yesterday.
Wish you all the best my friend, I’ve been shocked in one hand with 120 and that didn’t feel pretty so 400 is hard to imagine. This dude shocks himself all the time and you did what was right by getting checked given your circumstances. Best wishes friend! I’m sure you’ll be totally well.

10:46: "energy drops by the inverse square law" -- @ElectroBOOM you got this wrong. Since high voltage lines are a line source and not a point source, it drops as the area of a cylinder (1/r), not a sphere (1/r^2).
That formula is only when you are dealing with an _infinite_ straight line, and high voltage power lines are not infinite (nor typically entirely straight). The reality is that if you are very close to them, the formula will be close to the cylinder formula, but as you get farther away it turns more and more into the inverse square law. For the distances talked about in this video, realistically, it's probably somewhere in between the two...
@2:32 is basically what we experience in Greenland, because the air is so dry. I discharge myself on the door handle with a key. Playing Basketball is WICKED fun in-doors in Greenland, you charge up so fast and you can hear the arcs between the ball and the players. In school we just chased each other around with a finger pointing at each other, while dribbling and tried to shock each other. The fastest way to charge, was dribbling and "brushing the ball without touching it"
For some reason, I can't stop laughing after imagining children running after each other with their fingers pointed at each other and an evil electric look in their eyes. 😹
Bite the steel transmission tower. Bite it. I found an unused tower. With bone-conduction, you hear all kinds of tweeks and descending tones, just like a Star Wars blaster-battle. It's just the wind, making the tower creak. Pew pew pewwww. If you bite an in-use transmission tower, instead you hear a loug 120Hz buzz, but it keeps changing, leaping to different intensities, as huge industrial loads turn on and off.
If Mehdi ever lives next to any Electric Power Centers, Canada would've gotten a Guinness World Record for the most amount of times a power outage occurred on earth
Lived next to powerlines for a few years and there is something else to consider; It can get quite noisy/annoying. Rain, fog, snow or ice and the lines start crakling and humming. After ~1 hour I got a weird headache, like permanent pression on the entire skull. Not painful, but relieving when the sound finally stopps, silence, feels like a pressure equalization.
bro all emr causes oxidative stress and oxidative stress causes cancer...... So yes emr causes cancer including power lines and wifi etc.... Can't believe people take medical advice from RUclipsrs!
I suppose it depends on the kind of line. I know most of the ones distributing power to neighborhoods and such don't bother me, but the high-power long-distance transmission lines are something else. There's a line that goes by 100 yards from my house and when it is lightly drizzling, I can hear it even when I'm inside.
Yes, I was waiting for that, and it did not disappoint! (Poor Mehdi; if he ever wishes to branch out into more serious dramatic roles, he is forever going to be typecast as the idiot who grabs live wires.)
Mehdi, your vids have been entertaining me for years, and slowly getting me more and more curious about electronics until I finally bought a soldering kit last week. I've already successfully completed two projects, making a crappy mic with a little electret capsule and an audio jack, then (the _real_ test) repairing an ancient XBox 360 controller with a frayed cable. Desoldered the wires, cut & stripped them, and did a very ugly job re-soldering them. And it actually works! I can play Dark Souls again! I know you get comments like this all the time, but I just wanted to say thanks for being such a good teacher. I appreciate you not only sharing your knowledge, but especially inspiring folks like me to take up a hobby I never thought I'd pursue.
well done, i've been in the electronics industry over 40 years now. i suggest you buy a temperature controlled iron so you can practice using lead free solder and a hot air rework heater for surface mount components. ali express is ok for home use, they also have some great kitsets. good luck on your new hobby
My best advice to you buddy is watch a couple of videos on soldering it helped loads. There's lots of different soldering wire for different projects and some work better than others depending on what you're making, Also a variable temperature soldering iron that you can adjust when soldering delicate components because a lot of components will burn really quickly. I have a 80 watt variable temperature soldering iron that goes from about 30 watt for headphones up to 80 to 18650 batteries.. Dirt cheap to buy in $20. 👍
Dude great job! I actually dripped VERY HOT solder on my leg and it didn’t hurt nearly as much as I thought it would. It left a mark, and a little metal bead, and it healed in a few days. I had my leg angled after that.
If the solder joint looked clumpy or ugly, next time make sure the iron is held to the wire or copper trace on circuit board firmly and long enough (usually a few seconds) to get good and hot before you apply lead based rosen core solder (60-40 is a good solder for general purpose). Avoid silver based lead free solder since it is actually horrible to work with.
i work at a power plant and when you pass under those high voltage cables while it rains, it sounds like a fly swatter killing a bunch of small mosquitoes, it's cool i guess, a bit scary
7:34 For a moment there, I thought you were about to expose another Thorium infused negative ion scam device, but it actually turned out to be a great demo! I find it fascinating to watch the voltage chart move in real time. First time I get an idea of the scale involved.
@ChristopherBarker-r7m Cool! I used to watch Mr Mehdi's videos from 4th grade during covid 19 pandemic, I learnt a whole lot from him I am in grade 8 now, but still, fantstic!You should check out his 101 series they are gold! Good luck!
10:35 there’s a very famous Australian movie called “The Castle” that is exactly about this. The main character famously says “ah, the serenity!” But as an electrical engineer I would very highly recommend another great Australian movie, “Malcolm”, a comedy about a young man who gets fired from a tram depot workshop for too much hacking the electrical network. It turns into Oceans 11 for DIY electronics nerds. Merry Christmas!
Mehdi, just a small warning when you shock yourself while being grounded. Always avoid the travel path of the electricity to cross your heart as on 4:50. If the shock hits your heart during the repolarization phase (T-wave on ECG), a 7% change, it's ventricular fibrillation and game over without a defibrillator. Just a friendly reminder from a cardiac electrophysiologist with a passion for high voltage projects. I've shocked myself many times but always keep the ground at the same side of my body. Love your work! ❤
X-ray engineer here.........keep one hand in your pocket ;) A rule "not" to die by LOL Talking of Defibs, take a moment to look at how they work and the fact there powered usualy by a simple battery it's the frequency that gets you not the voltage. Great video but here in the UK long term studdies on living within high EMF zones make for some dire results, acumulitive effects over decades are not great especialy in the young. On a brighter note go check out some great art instalations where hundreds of florecent tubes are placed verticly in the ground under power lines. :)
@hereward1971 indeed, for arrhythmia induction the frequency is a very important factor. You can induce premature contractions with as little as 3V. Interestingly, 50Hz is a very effective frequency to induce fibrillation and we often use it to induce fibrillation to test cardioversion treatments. Defibrillators use the smaller battery to charge up a high voltage capacitor, around 1200V for higher power ones, which can then deliver a biphasic shock between 200-360J in 10ms. Pacing, in the case of no electrical heart activity, uses indeed a simple 9V battery with just some switching circuitry.
While frequencies below visible light cannot directly cause cancer, there are publications showing how 900MHz radio signals (same as GSM) may cause thyroid gland dysfunction. I have also spoke with a few people working in facilities with radio equipment at a close frequency (~915MHz), and they mentioned they got hypothyroidism from the relatively high power (~10W) radiations. So it's better to limit your exposure to low frequency high power signals as well.
@@MahdiMohammadi0 people still don't understand that RF is a catalyst it allows chemicals to form bonds that they could not do in nature just like light cured UV acrylic resins or epoxies and glues . RF,EMF magnetism light and heat and cold can allow certain chemicals to react together .basic chemistry or physics for some .
Back in 90’s I sold a fluorometer to a Lawrence Livermore researcher who was studying emf on live cells. It was a time of heightened fear that emf was to blame for various health issues. Sadly, he was found to be fudging data that was fueling emf concerns. He was fired, banned from research, and lost his credentials. It’s very rare for this kind of thing to happen, but it can have lasting influence on public fears.
I used to live "nearby" a power substation, or distribution station, I don't know exactly. Where I live, we use to fly kites in september and the whole substation and nearby transmission lines and towers were plastered with "Danger, High Voltage, No Kite Zone", etc. I never developed any problems and never had testicular cancer in any of my 5 ones.
Honestly? Ever since I started looking into how electricity and the distribution systems work, I can't help but look at the high voltage power lines with fascination and awe. So much power, so much energy, running through there... And just how violently would one be ripped apart if they touched one while grounded. Not to mention the videos of those things when they short. So violent. So powerful. So deadly. Just... wow. That we're able to use those things safely is just... Wow
5:01 | its especially more dangerous to ground yourself in the UK if your earthing system is TNC-S (Terra Neutral Combined-Seperated) also known as PME, this is because if the CNE conductor (combined netural earth) breaks somewhere underground your body would then be electrocuted with 240 volts and you become the return path for the electrical installation.
10:50 Is this correct? The inverse square law applies to points (and things that can be approximated as points), which a high-voltage power line isn't. If I remember right, the drop-off from a cable would be 1/r.
I live in a rural area and the guy who owned the farm raised angora goats . Sometimes the young goats would develop long bone deformaties ,which he blamed on the high tension lines that passed over a small part of his property. He knew full well that goats needed more than just fresh grass to have full nutrition because he told me about that . But that was not the cause of the bone problems as far as he was concerned , it had to be the EMF from the HT line.
Aha! I found a mistake at the end! 10:45 Energy drops by te inverse square law. Power line are essentially infinite strings. And for one-dimensional string it's 1/r law where r - has the first power. And for a capacitor (if we neglect border-effects) intensity doesn't drop with distance at all. 🧐
Yes, a small error compared to the information conveyed. For the separation of the power lines, and the proximity to them, it might be something between the power of 1 or two. Near fields can be quite complicated.
@@edwardlulofs444 of course it's a tiny mistake, considering the amount of material in the video. And it doesn't change general point that power line aren't THAT dangerous as some people portray them. Just wanted to clarify the matter.
Ooh you're right for straight wires i think! But I guess for power distribution centers that everything is clumped in a place it could be inverse squared.
@ yes, it’s complicated. In physics, when I was in college 30 years ago, we just used arrangements that were clear what the answer is. But I think this product Brilliant is really good and more students can learn from it than boring books and classes. You are such a great educator and are making a great contribution. Keep up the great work.
Few weeks before people from electrical department were working on the high voltage power lines close to house. Something went wrong and the power line snapped and falled on the ground. It caused a loud sound and all the electrical appliances in my neighborhood house destroyed. In our house the washing machine was only affected. But lucky no one got injured.
4000 meters? Odd way to say 4km 😂 I remember a story about someone on a farm stealing electricity from high tension lines by setting up some loops on the ground.
A frustrating thing about buying a house near power lines, is that it doesn't matter if you understand that there is no danger from EMF. What matters is what potential buyers think when you go to sell it.
@@jacobvoracek2349 oh boy, lots of people. Most of those power lines were built out away from cities but as cities expand (I live in Colorado) all the land around those lines get zoned and homes built.
Just tell them they can expect a spectacular light show during intense storms, especially if lightning is involved and it occurs regularly. Great selling point. Who needs fireworks, when you got coronas and jacob's?
There needs to be a general science education award for this work. Seriously, I have never seen such high quality educational material in my 50 years of teaching.
There had been at least one study that indicated proximity to power transmission correlated with increased the rate of childhood leukemia. The problem is that there are so many potential confounding factors that this correlation can not be taken at face value. For example proximity to power transmission lines correlates with proximity to highways, and thus periodic exposure to carcinogens from fresh pavement.
That one study was also a long time ago, and people have done a lot of studies since which found contrary results. Taking all of the research that everyone has done over many years, there is really no evidence that there is even any statistical correlation at all (let alone causation)...
One whole study, huh? What was the sample size? What was the margin of error? How long ago was it conducted? How well did it control for other environmental factors, such as radon gas emission from the soils under the houses or other possible sources? One single study is NEVER sufficiently robust, and intellectual honesty demands that you acknowledge this.
I find it so funny that this man can make us laugh and learn something by just making an accidental mistake, like the balloon from 9:50 . God i wish more Teachers were like this, bringing joy to the education of science. Keep posting more content, Mehdi!
As an electrical engineer... Watching your videos is like watching someone play with aggravated poisonous snakes! I'm constantly on edge! Have a good Christmas!
I think its not a secret that 90% of these are staged by professional electrical engineer, aka Mehdi himself. By now I watch his videos to learn. Even this one gave so much new info. But the rest 10% >:D
If he was incompetent, he'd be dead by now!. I'm often asked if I'm still scared by electricity. My answer is simply "Yes... and that why I'm still alive!"
i live 50m to a powerline tower, other than turning on the light with my brain i have no side effects, but i mean, think about when you are tired and you forget to turn off the light
This video is extremely helpful for showing exactly what everyday effects of high voltage and static charging are like where we really don't notice it. Especially for people who just cannot understand or accept being told something is safe and why. And then they fall for scam products that "promise" to meet their confused sense of how things work. I hope you could do another video that includes similar testing that takes into consideration humidity levels/temperature could effect it. It can be very annoying to find yourself constantly being statically shocked in winter time and depending on what you wear can really be annoying not knowing why it happens constantly.
Learned something new. I was a Missile Tech on submarines, and we overwhelmingly worked on high pressure air/nitrogen and Hydraulic systems. We did, however, have to work with electric systems. Mostly when shit broke. We had little actual training other than "turn off source or die", and "don't fry shit with ESD". We had to do PMs on our grounding straps to ensure they maintain a certain resistance, and I could never get an answer from my division on why the hell a grounding strap required such high resistance. Seems like a high resistance would prevent it from discharging static build up fast enough. Guess not, and it makes sense now that it's to prevent electric shock.
I live pretty much directly under a medium voltage transmission line and I have for years. I don't even get higher levels of static in the house. It's just, I have wires when I look up. But it did mean the property was significantly cheaper when I bought it because people apparently don't like to live near critical infrastructure.
While the high voltage lines may not pose a direct danger I do remember seeing research on Childhood and Adult Leukaemia as well as other cancers. The risk of getting these cancers was increased in those who lived near High Voltage lines. The suggestion was not that the high voltage was causing the increased cancers, but that the high voltage attracted the radioactive decay products of radon gas. This essentially creates a cloud of radioactive particles that is slightly denser than normal levels. There was also something about how these alpha particles bond with water droplets in the air under high voltage lines and that makes them more sticky in the sense that you are more likely to inhale them or have them stick to skin. I am not saying its unsafe, but its just not as simple as assessing the high voltage lines in isolation.
@oOMonkeyMagicOo There was such a story in the February 1996 "New Scientist" magazine. Even then it was uncertain whether there was causality. Further studies appear to raise even more doubts.
The power company paid my uncle (master electrician) to lease his land to run high voltage transmission lines through it. He erected a couple of poles with power lines between them, underneath and perpendicular to the transmission lines. This induced a current into my uncle’s line and he siphoned off power. Idk if this was just a tale he liked to tell or if it really happened. Seems plausible though.
@geebsterswats I think it was just a tale. What was the output voltage from his wires? How could he adjust the voltage? I think that what he was claiming was that he created a simple transformer, but what was the turns ratio? Furthermore, voltage is induced in the secondary, which would have been his parallel wires, by the coupling of a time-changing magnetic flux density between one of the high-voltage wires and one of your uncle's parallel wires. Not much magnetic flux would be coupled by having the "output" be a single straight wire perpendicular to the "input" wire. He would have had much better coupling by making a big multi-turn coil and oriented it so that the axis of the coil was perpendicular to the high-voltage wire. And his coil would need to be much closer to one of the high-voltage wires than to the other two. I don't think that your uncle's story seems very plausible after considering the details.
It would need to be parallel, and it would give you some power, in theory. The problem is, the transmission lines have 3 wires, a neutral and 2 powered that are 180 out of phase. The fields from the powered wires would cancel.
I live literally less then 10 meters of distance of the base of a HV power line. I think is 150kV, its one of those towers that have "switches" that open sometimes (and close) and my backyard becomes illuminated like is noon. There is interferences when this switches close/open, I can her even on my bluetooth headphones - yeah.. not ideal, but is ok. The problem is when a thunder struck the tower, this makes almost every router burn here, because of the longer cables, I need put some device to clamp this problems, but yeah, is rare, sometimes is just easy turn off everything when a thunder storm its starting... But yeah, if anyone wants to me experiment something, just suggest here. By the way Mehdi, I like the view of the towers and cables. Remembers that they are peaceful, just working as intended, sleeping pillars of our technology - just don't mess with them.
haha I wonder if at that distance it would make florescent light tubes glow. like a year ago here we had a thunder storm so bad it fried a lot of stuff that wasnt even plugged in. It fried our wireless router because the antennas picked it up, even my backlit keyboard that was not connected was glowing with every strike XD like the led in the video.
There are about 15 houses that set underneath the high power lines that run off the distribution center that sits in the field beside our houses and all the women who live in those houses that have gotten breast cancer.. every single one of them in all the houses that sit underneath that line...
Sure, popping like a fuse was a bit of hyperbole, but it only takes tens of milliamps at mains voltage and frequency over hundreds of milliseconds to be lethal which is much less than a resistor or headphone lines can handle.
Somebody did that with a radio cord (direct AC) by inserting a poled halogen bulb into it, inserted it into a pop bottle and then plugged it in. **POP!!**
I'll tell you a small personal story that has to do with proper grounding of your electrical system. I moved some things in my room, and fixed my audio mixer to the wall, and thus grounding its metal body. I connected a 3.5mm jack to RCA cable to my laptop so I could use the mixer with it. I was holding the outer ring of one of the RCA conectors (which is their ground), and then touched the body of thw mixer with that same hand. That action gave me quite a shock on my hand haha. But then I got curious and pulled out my multimeter to find out what was that, since it didn't feel like static at all. Turns out, the ground of thw RCA cables were LIVE at 120V AC, somehow. I decided to unplug my laptop from ita charger, and that reading disappeared. Measuring between physical ground, and the ground of the charger showed that it was indeed live. After some digging, the ungrounded and not polarized extension cord that everything is plugged into was connected backwards, and somehow sent thw live voltage down to the ground components of my laptop. Switching that around fixed the issue before any morw damage could be made. Stay safe folks!
When I was a child, I was living in an area where 2 high voltage transport lines were a couple of streets away. One of them is 735 kVv and the other 315 kV. I remember that when I was riding my bike under those you could hear them buzzing and I learned very early not to touch the metal frame of the bike. 😆 You could get a pretty unpleasant shock from my memories !
You do hint at a possible mechanism for health impact at the end of the video when you mention that the high-voltage lines are giant air purifiers. They'll generate a small amount of ozone and nitric oxides through corona discharge. This could exacerbate asthma, and the free radicals could lead to higher cancer rates over time. I don't know what concentration of ozone would be present around 400kV lines or if it would be enough to cause adverse health effects. My guess is less health impact than living near a highway or busy road.
yeah so close that you can reach the powerline with your hand when you're at the top floor of your house. my neighbor's house is like that, it's scary to think that you can just grab it to self-destruct
not sure about power lines, but people in Brazil who are living close to power windmills (not sure if term is correct) are living a hell. Not because of electricity, but noise and dust are horrendous. Of course they didn't moved to there, government just built those close to their houses.
They are called wind turbines in English. Their gearboxes and massive blades might be noisy and it looks like they induce advanced settling of sand particles. Anyway, Brazil has a massive coastline, plenty of floating wind farms can be built within Brazilian waters. But, tbh, I think that the destruction of the Amazon jungle should be a bigger concern for Brazilians.
I used to fly on C-5B Galaxy's a lot. There are two bunk rooms one of which is next to an AC load center, big ass circuit breaker panel, that had one bunk against the same wall. Covered by plastic. I had some of the weirdest dreams when I slept in that bunk. I was never warned of the phenomenon, so it wasn't just in my head. I know the electricity won't hurt you, as long as you don't touch it, but it sure does mess with your brain if you get close enough, long enough.
3:16 That helmet you just put on--acts like an antenna. You need to ground it before it does any good! EDIT: LMAO... you KNOW I was just joking... I had no idea you were about to spend several minutes on this topic! lol (BTW, wrist straps have a resistor in them to SLOWLY bleed off the current.... but of course, you're probably about to cover that, aren't you?) Double edit... YEP... your very next words..
I live right under 110kV power lines. Have done for 40 years. They go 12 feet above my roof. Never had any symptoms of electromgnetic interference. They don't interfere with the TV signal, no problem with any electronics. The *only* time I've ever detected anything was when I got a tingle off the earthing around a co-ax TV aerial cable that ran about 30 feet at right angles to the wires. A meter showed some kV of voltage but of course next-to-zero current.
@@chrisdwalter In my village, we have the same experience with 300kV power lines. When passing underneath, you can clearly hear the 'dzzz' sound. On rainy days, if you're passing by on a bicycle, you can even feel the electric energy. Is it same ?
Correct me if I'm wrong, but the power from a power line does not decay by inverse square law. Power lines are linear/cylindrical electrical charges that lose power inversely proportional. 10:44
5:30 "With ESD wristbands the static dissipates quickly" Isn't it the opposite? The 1 MOhm resistance massively limits the current of the discharge, causing the static to dissipate slowly, without sudden surges. A sudden discharge would go against the principle of ESD, which is not grounding, but making sure that person, work-surface, workpiece, equipment, whatever shares the same potential.
Quickly is a matter of application here. 1.0 MΩ is recognized as the start of the dissipative range for materials. These materials allow safe conduction of a static charge slowly enough to not damage ESD sensitive devices. I often measure discharge times of less than 0.1 seconds from an initial charge or 1 kV when testing "static safe" materials for ESD control. The 1.0 MΩ, quarter watt resistor in your wristband cord also provides you personal protection by limiting current to less than 0.0005 amperes (0.5 milliamperes) in case you encounter an over, or here what is referred to as a Mehdi voltage. Some of those earthing discussion and product sales sites fail to mention the importance of including these "safety" resistors that will open waaaaay before a circuit breaker will trip.
A significant study linking living near high power transmission lines to leukemia is the "Childhood leukemia and distance from power lines" study published in the British Medical Journal (BMJ) in 2005, which found that children residing within 200 meters of high-voltage power lines may have a significantly increased risk of developing leukemia, with a potential 70% higher risk compared to those living further away; this study is considered one of the largest case-control studies on childhood cancer ever conducted.
@@Molon_Labe1776 yep and that's just the tip of the ice berg .Magnetic fields man made or natural can steer harmful particles towards a specific area where you don't want them to go same issues where people live where the Earth's field dips into the ground .and energetic particles get steered just like how a cathode ray tube works to deflect the electron beam
There are serious problems with that study (pmc.ncbi.nlm.nih.gov/articles/PMC4617228/) and more comprehensive studies have debunked that finding (www.nature.com/articles/s41416-018-0097-7)
The problem is that we do not know whether these children had amalgam dental fillings. Alternating electromagnetic fields can attack these metal-containing dental fillings electrolytically and thus be a permanent source of metal ions, e.g. mercury. Some mercury compounds are considered to be carcinogenic.
@JargonFootprint yes that is true amalmgum mixed with an electrolyte and being exposed to EMF RF and other forms of resonant energies at frequencies can cause all kinds of problems .The other issue is how magnetic field can steer high energy particles from space to a specific direction based on the Earth's flux lines and locations of power distribution systems .Too many things to calculate but if you know both directions velocity and energy you can predict the direction of the focused energy .Just like in a CRT electrons are steered by the yoke .the same way ground plains steer RF and multiply power and direct it .
On a related note, when I was in highschool, I wore a thick polyesther coat in the winter as well as boots with rubber soles. If I made the mistake of taking my coat off before removing my earbuds, I'd get a static charge right into my ear canals
9:10 please tell me what is the phenomena behind this why high voltage current flows through you even when you are standing On non conductive material? For example why touching live wire with pvc pipe won't electrocute while standing On pvc flooring and touching live wire with bare hand Will electrocute?

10:46: "energy drops by the inverse square law" -- @ElectroBOOM you got this wrong. Since high voltage lines are a line source and not a point source, it drops as the area of a cylinder (1/r), not a sphere (1/r^2).
Inverse law
It's likely a complex mix between the two since the towers are grounded and short the field so it's not perfectly cylindrical.
Nerds 😂
That formula is only when you are dealing with an _infinite_ straight line, and high voltage power lines are not infinite (nor typically entirely straight).
The reality is that if you are very close to them, the formula will be close to the cylinder formula, but as you get farther away it turns more and more into the inverse square law.
For the distances talked about in this video, realistically, it's probably somewhere in between the two...

In school we just chased each other around with a finger pointing at each other, while dribbling and tried to shock each other. The fastest way to charge, was dribbling and "brushing the ball without touching it"

Bite the steel transmission tower. Bite it.
I found an unused tower. With bone-conduction, you hear all kinds of tweeks and descending tones, just like a Star Wars blaster-battle. It's just the wind, making the tower creak. Pew pew pewwww. If you bite an in-use transmission tower, instead you hear a loug 120Hz buzz, but it keeps changing, leaping to different intensities, as huge industrial loads turn on and off.

Lived next to powerlines for a few years and there is something else to consider; It can get quite noisy/annoying. Rain, fog, snow or ice and the lines start crakling and humming.
After ~1 hour I got a weird headache, like permanent pression on the entire skull. Not painful, but relieving when the sound finally stopps, silence, feels like a pressure equalization.

Mehdi, your vids have been entertaining me for years, and slowly getting me more and more curious about electronics until I finally bought a soldering kit last week. I've already successfully completed two projects, making a crappy mic with a little electret capsule and an audio jack, then (the _real_ test) repairing an ancient XBox 360 controller with a frayed cable. Desoldered the wires, cut & stripped them, and did a very ugly job re-soldering them. And it actually works! I can play Dark Souls again! I know you get comments like this all the time, but I just wanted to say thanks for being such a good teacher. I appreciate you not only sharing your knowledge, but especially inspiring folks like me to take up a hobby I never thought I'd pursue.
If it's DS2, it was a waste of time!
well done, i've been in the electronics industry over 40 years now. i suggest you buy a temperature controlled iron so you can practice using lead free solder and a hot air rework heater for surface mount components.
ali express is ok for home use, they also have some great kitsets.
good luck on your new hobby
My best advice to you buddy is watch a couple of videos on soldering it helped loads. There's lots of different soldering wire for different projects and some work better than others depending on what you're making, Also a variable temperature soldering iron that you can adjust when soldering delicate components because a lot of components will burn really quickly. I have a 80 watt variable temperature soldering iron that goes from about 30 watt for headphones up to 80 to 18650 batteries.. Dirt cheap to buy in $20. 👍
Dude great job! I actually dripped VERY HOT solder on my leg and it didn’t hurt nearly as much as I thought it would. It left a mark, and a little metal bead, and it healed in a few days. I had my leg angled after that.
If the solder joint looked clumpy or ugly, next time make sure the iron is held to the wire or copper trace on circuit board firmly and long enough (usually a few seconds) to get good and hot before you apply lead based rosen core solder (60-40 is a good solder for general purpose). Avoid silver based lead free solder since it is actually horrible to work with.
Hi mehdi just checking in after 5 years and glad to see you're still alive

10:35 there’s a very famous Australian movie called “The Castle” that is exactly about this. The main character famously says “ah, the serenity!”
But as an electrical engineer I would very highly recommend another great Australian movie, “Malcolm”, a comedy about a young man who gets fired from a tram depot workshop for too much hacking the electrical network. It turns into Oceans 11 for DIY electronics nerds. Merry Christmas!
I was hoping someone had said exactly this :D hahah! How's that serenity!
I love that when you say "Scam. Scam I tell you!", we can see the scope reading going way higher than it was, proving the point even more.
Mehdi, just a small warning when you shock yourself while being grounded. Always avoid the travel path of the electricity to cross your heart as on 4:50. If the shock hits your heart during the repolarization phase (T-wave on ECG), a 7% change, it's ventricular fibrillation and game over without a defibrillator. Just a friendly reminder from a cardiac electrophysiologist with a passion for high voltage projects. I've shocked myself many times but always keep the ground at the same side of my body. Love your work! ❤
Mehdi is an engineer, he doesn't have a heart.
what is meant by keep ground on same side of body
@@khush1894 Put left foot in a puddle, only touch live power line with left hand. That way your heart won't turn to charcoal.
X-ray engineer here.........keep one hand in your pocket ;) A rule "not" to die by LOL Talking of Defibs, take a moment to look at how they work and the fact there powered usualy by a simple battery it's the frequency that gets you not the voltage. Great video but here in the UK long term studdies on living within high EMF zones make for some dire results, acumulitive effects over decades are not great especialy in the young. On a brighter note go check out some great art instalations where hundreds of florecent tubes are placed verticly in the ground under power lines. :)
@hereward1971 indeed, for arrhythmia induction the frequency is a very important factor. You can induce premature contractions with as little as 3V. Interestingly, 50Hz is a very effective frequency to induce fibrillation and we often use it to induce fibrillation to test cardioversion treatments.
Defibrillators use the smaller battery to charge up a high voltage capacitor, around 1200V for higher power ones, which can then deliver a biphasic shock between 200-360J in 10ms. Pacing, in the case of no electrical heart activity, uses indeed a simple 9V battery with just some switching circuitry.

While frequencies below visible light cannot directly cause cancer, there are publications showing how 900MHz radio signals (same as GSM) may cause thyroid gland dysfunction. I have also spoke with a few people working in facilities with radio equipment at a close frequency (~915MHz), and they mentioned they got hypothyroidism from the relatively high power (~10W) radiations. So it's better to limit your exposure to low frequency high power signals as well.

Back in 90’s I sold a fluorometer to a Lawrence Livermore researcher who was studying emf on live cells. It was a time of heightened fear that emf was to blame for various health issues.

5:01 | its especially more dangerous to ground yourself in the UK if your earthing system is TNC-S (Terra Neutral Combined-Seperated) also known as PME, this is because if the CNE conductor (combined netural earth) breaks somewhere underground your body would then be electrocuted with 240 volts and you become the return path for the electrical installation.

10:50 Is this correct? The inverse square law applies to points (and things that can be approximated as points), which a high-voltage power line isn't. If I remember right, the drop-off from a cable would be 1/r.
I live in a rural area and the guy who owned the farm raised angora goats . Sometimes the young goats would develop long bone deformaties ,which he blamed on the high tension lines that passed over a small part of his property.
He knew full well that goats needed more than just fresh grass to have full nutrition because he told me about that .
But that was not the cause of the bone problems as far as he was concerned , it had to be the EMF from the HT line.

Few weeks before people from electrical department were working on the high voltage power lines close to house. Something went wrong and the power line snapped and falled on the ground. It caused a loud sound and all the electrical appliances in my neighborhood house destroyed. In our house the washing machine was only affected. But lucky no one got injured.
I work at a transformer factory. Recently moved and happens that I now live about 4000 meters from that bridge. Seems like there's some potential.
4000 meters? Odd way to say 4km 😂
I remember a story about someone on a farm stealing electricity from high tension lines by setting up some loops on the ground.
A frustrating thing about buying a house near power lines, is that it doesn't matter if you understand that there is no danger from EMF. What matters is what potential buyers think when you go to sell it.

There needs to be a general science education award for this work.
Seriously, I have never seen such high quality educational material in my 50 years of teaching.
There had been at least one study that indicated proximity to power transmission correlated with increased the rate of childhood leukemia. The problem is that there are so many potential confounding factors that this correlation can not be taken at face value. For example proximity to power transmission lines correlates with proximity to highways, and thus periodic exposure to carcinogens from fresh pavement.
It probably also correlates with lower income - rich folk can afford to live in more scenic areas that don't have big power lines.
That one study was also a long time ago, and people have done a lot of studies since which found contrary results. Taking all of the research that everyone has done over many years, there is really no evidence that there is even any statistical correlation at all (let alone causation)...
Correlation is not causation. I could imagine the next frenzy being heavy drinkers and smokers blaming 5G transmitters for their health problems lol.

One whole study, huh? What was the sample size? What was the margin of error? How long ago was it conducted?

This video is extremely helpful for showing exactly what everyday effects of high voltage and static charging are like where we really don't notice it. Especially for people who just cannot understand or accept being told something is safe and why. And then they fall for scam products that "promise" to meet their confused sense of how things work. I hope you could do another video that includes similar testing that takes into consideration humidity levels/temperature could effect it. It can be very annoying to find yourself constantly being statically shocked in winter time and depending on what you wear can really be annoying not knowing why it happens constantly.
Learned something new. I was a Missile Tech on submarines, and we overwhelmingly worked on high pressure air/nitrogen and Hydraulic systems. We did, however, have to work with electric systems. Mostly when shit broke. We had little actual training other than "turn off source or die", and "don't fry shit with ESD".
We had to do PMs on our grounding straps to ensure they maintain a certain resistance, and I could never get an answer from my division on why the hell a grounding strap required such high resistance. Seems like a high resistance would prevent it from discharging static build up fast enough. Guess not, and it makes sense now that it's to prevent electric shock.

I live pretty much directly under a medium voltage transmission line and I have for years. I don't even get higher levels of static in the house. It's just, I have wires when I look up.
But it did mean the property was significantly cheaper when I bought it because people apparently don't like to live near critical infrastructure.
Actually that's an idea for first time home buyers, power lines are your friend?
While the high voltage lines may not pose a direct danger I do remember seeing research on Childhood and Adult Leukaemia as well as other cancers. The risk of getting these cancers was increased in those who lived near High Voltage lines. The suggestion was not that the high voltage was causing the increased cancers, but that the high voltage attracted the radioactive decay products of radon gas. This essentially creates a cloud of radioactive particles that is slightly denser than normal levels. There was also something about how these alpha particles bond with water droplets in the air under high voltage lines and that makes them more sticky in the sense that you are more likely to inhale them or have them stick to skin. I am not saying its unsafe, but its just not as simple as assessing the high voltage lines in isolation.
@oOMonkeyMagicOo There was such a story in the February 1996 "New Scientist" magazine. Even then it was uncertain whether there was causality. Further studies appear to raise even more doubts.
An interesting channel to check out is @doubleMinnovations as he is doing a lot of experimenting on emf
The power company paid my uncle (master electrician) to lease his land to run high voltage transmission lines through it. He erected a couple of poles with power lines between them, underneath and perpendicular to the transmission lines. This induced a current into my uncle’s line and he siphoned off power. Idk if this was just a tale he liked to tell or if it really happened. Seems plausible though.
@geebsterswats I think it was just a tale. What was the output voltage from his wires? How could he adjust the voltage? I think that what he was claiming was that he created a simple transformer, but what was the turns ratio? Furthermore, voltage is induced in the secondary, which would have been his parallel wires, by the coupling of a time-changing magnetic flux density between one of the high-voltage wires and one of your uncle's parallel wires. Not much magnetic flux would be coupled by having the "output" be a single straight wire perpendicular to the "input" wire. He would have had much better coupling by making a big multi-turn coil and oriented it so that the axis of the coil was perpendicular to the high-voltage wire. And his coil would need to be much closer to one of the high-voltage wires than to the other two. I don't think that your uncle's story seems very plausible after considering the details.
It would need to be parallel, and it would give you some power, in theory. The problem is, the transmission lines have 3 wires, a neutral and 2 powered that are 180 out of phase. The fields from the powered wires would cancel.
Just a tale, it's even a Mythbusters experiment of a farmer guy who build "coil antenas" to get Free induction energy
Went through 4 years of electrical school..but i learn more in a 20 minute Electraboom video! 😂😂😂
We used to take florescent light tubes under the powerlines to watch them light up. Your friend at the bridge should have tried that.
I live literally less then 10 meters of distance of the base of a HV power line. I think is 150kV, its one of those towers that have "switches" that open sometimes (and close) and my backyard becomes illuminated like is noon. There is interferences when this switches close/open, I can her even on my bluetooth headphones - yeah.. not ideal, but is ok. The problem is when a thunder struck the tower, this makes almost every router burn here, because of the longer cables, I need put some device to clamp this problems, but yeah, is rare, sometimes is just easy turn off everything when a thunder storm its starting... But yeah, if anyone wants to me experiment something, just suggest here. By the way Mehdi, I like the view of the towers and cables. Remembers that they are peaceful, just working as intended, sleeping pillars of our technology - just don't mess with them.
Hmmm so can you actually experiment make free energi with that ?
@avitferdiansyah1792 it wouldn't be free. The people monitoring the power lines can detect if you're wirelessly 'siphoning' off of high voltage lines
haha I wonder if at that distance it would make florescent light tubes glow. like a year ago here we had a thunder storm so bad it fried a lot of stuff that wasnt even plugged in. It fried our wireless router because the antennas picked it up, even my backlit keyboard that was not connected was glowing with every strike XD like the led in the video.
@@mromutt oh fuck, that must've been awesome! I wonder if it powered any wireless chargers, even if just for a brief period of time. XD

You wouldn't pop like a fuse, those thin phone wires would melt long before, and likely a resistor before that
There are esd caps in charges that prevent that and just trip your gfci or destroy your charger
The current would be extremely lethal long before it reached a large enough magnitude to melt those wires.
Sure, popping like a fuse was a bit of hyperbole, but it only takes tens of milliamps at mains voltage and frequency over hundreds of milliseconds to be lethal which is much less than a resistor or headphone lines can handle.
Hey, there are 100mA fuses!
1:00 did you just power a 12 v incandescent lightbulb with 120 for more than 3 seconds??
No. It's a standard LED globe designed for 120V. Otherwise, it would've blown up.
Plus, it would flicker with every AC cycle. Standard LED bulbs have filters to prevent this.
Somebody did that with a radio cord (direct AC) by inserting a poled halogen bulb into it, inserted it into a pop bottle and then plugged it in. **POP!!**
Yes I think the source is 12 volts not 120 as he purposely short it with his body

i do love the look of high voltage powerlines. so much that i make small scale towers to hold my solar lines
I'll tell you a small personal story that has to do with proper grounding of your electrical system.
I moved some things in my room, and fixed my audio mixer to the wall, and thus grounding its metal body.
I connected a 3.5mm jack to RCA cable to my laptop so I could use the mixer with it. I was holding the outer ring of one of the RCA conectors (which is their ground), and then touched the body of thw mixer with that same hand. That action gave me quite a shock on my hand haha. But then I got curious and pulled out my multimeter to find out what was that, since it didn't feel like static at all. Turns out, the ground of thw RCA cables were LIVE at 120V AC, somehow. I decided to unplug my laptop from ita charger, and that reading disappeared. Measuring between physical ground, and the ground of the charger showed that it was indeed live.
After some digging, the ungrounded and not polarized extension cord that everything is plugged into was connected backwards, and somehow sent thw live voltage down to the ground components of my laptop.
Switching that around fixed the issue before any morw damage could be made. Stay safe folks!

When I was a child, I was living in an area where 2 high voltage transport lines were a couple of streets away. One of them is 735 kVv and the other 315 kV. I remember that when I was riding my bike under those you could hear them buzzing and I learned very early not to touch the metal frame of the bike. 😆 You could get a pretty unpleasant shock from my memories !
You do hint at a possible mechanism for health impact at the end of the video when you mention that the high-voltage lines are giant air purifiers. They'll generate a small amount of ozone and nitric oxides through corona discharge. This could exacerbate asthma, and the free radicals could lead to higher cancer rates over time. I don't know what concentration of ozone would be present around 400kV lines or if it would be enough to cause adverse health effects.
My guess is less health impact than living near a highway or busy road.
0:02 I live near a Live Tower Line(because electrical lines are always a part of a filipino city)

I hardly feel that Medhi is in any danger during his videos, but this actually made me cold sweat a bit 4:38
I live in village between two power lines. There is only chirping at rainy days. And yes, cool games with fluorescent lamps at night under the line.
0:34 I guess that's SKEPTICAL
0:30 Expecto patronum 🪄
😂😂😂
I am waiting for patrons?
It's interesting that RUclips/Google translate it as such. Harry Potter would be confused.
9:40 *blown capacitor PTSD intensifies*
not sure about power lines, but people in Brazil who are living close to power windmills (not sure if term is correct) are living a hell. Not because of electricity, but noise and dust are horrendous. Of course they didn't moved to there, government just built those close to their houses.
They are called wind turbines in English.
Their gearboxes and massive blades might be noisy and it looks like they induce advanced settling of sand particles.
Anyway, Brazil has a massive coastline, plenty of floating wind farms can be built within Brazilian waters.
But, tbh, I think that the destruction of the Amazon jungle should be a bigger concern for Brazilians.
I used to fly on C-5B Galaxy's a lot. There are two bunk rooms one of which is next to an AC load center, big ass circuit breaker panel, that had one bunk against the same wall. Covered by plastic. I had some of the weirdest dreams when I slept in that bunk. I was never warned of the phenomenon, so it wasn't just in my head. I know the electricity won't hurt you, as long as you don't touch it, but it sure does mess with your brain if you get close enough, long enough.
10:35 Dad, he reckons powerlines are a reminder of man's ability to generate electricity.
1:09 he did it purposely 😅
Still funny though😂
If you somehow found your name at 0:11 you have great patience and great vision
0:48 we are getting fancy with edits 😂
Haven’t watched this guy for nearly 2 and a half years but I’m back
the production quality on this video is really good, Mehdi! Great video!
3:16 That helmet you just put on--acts like an antenna. You need to ground it before it does any good! EDIT: LMAO... you KNOW I was just joking... I had no idea you were about to spend several minutes on this topic! lol (BTW, wrist straps have a resistor in them to SLOWLY bleed off the current.... but of course, you're probably about to cover that, aren't you?) Double edit... YEP... your very next words..
0:33 look at this magnificent hair in the nose in HD
I died at 1:22 🤣
Congrats on reaching 8 Million subscribers Mehdi
I've seen tiny arcs of electricity when petting a longhaired cat outdoors in the dark ! Does that mean cats will give me cancer ? 🤣🤣🤣
5:45 DONT TRY THIS!!
me: somebody WILL try this and die 😂
I live right under 110kV power lines. Have done for 40 years. They go 12 feet above my roof. Never had any symptoms of electromgnetic interference. They don't interfere with the TV signal, no problem with any electronics. The *only* time I've ever detected anything was when I got a tingle off the earthing around a co-ax TV aerial cable that ran about 30 feet at right angles to the wires. A meter showed some kV of voltage but of course next-to-zero current.
It must be scary doing roof repairs!
Apparently you don't live in the US. That amount clearance above a dwelling is illegal.
I thought you visited the bridge, so this must be the last video on this channel. Lol
Lol then Mehdi says: "Bridge experiment, you say ? Now you’ve given me ideas"
@@EmberStyle lol yea
I live near this bridge in maple grove, MN USA
@@chrisdwalter In my village, we have the same experience with 300kV power lines. When passing underneath, you can clearly hear the 'dzzz' sound. On rainy days, if you're passing by on a bicycle, you can even feel the electric energy. Is it same ?
Correct me if I'm wrong, but the power from a power line does not decay by inverse square law. Power lines are linear/cylindrical electrical charges that lose power inversely proportional.

5:30 "With ESD wristbands the static dissipates quickly"
Isn't it the opposite? The 1 MOhm resistance massively limits the current of the discharge, causing the static to dissipate slowly, without sudden surges. A sudden discharge would go against the principle of ESD, which is not grounding, but making sure that person, work-surface, workpiece, equipment, whatever shares the same potential.
I think he means "quickly" as in seconds, not "quickly" as in microseconds.
Quickly is a matter of application here.
1.0 MΩ is recognized as the start of the dissipative range for materials. These materials allow safe conduction of a static charge slowly enough to not damage ESD sensitive devices. I often measure discharge times of less than 0.1 seconds from an initial charge or 1 kV when testing "static safe" materials for ESD control. The 1.0 MΩ, quarter watt resistor in your wristband cord also provides you personal protection by limiting current to less than 0.0005 amperes (0.5 milliamperes) in case you encounter an over, or here what is referred to as a Mehdi voltage. Some of those earthing discussion and product sales sites fail to mention the importance of including these "safety" resistors that will open waaaaay before a circuit breaker will trip.
A significant study linking living near high power transmission lines to leukemia is the "Childhood leukemia and distance from power lines" study published in the British Medical Journal (BMJ) in 2005, which found that children residing within 200 meters of high-voltage power lines may have a significantly increased risk of developing leukemia, with a potential 70% higher risk compared to those living further away; this study is considered one of the largest case-control studies on childhood cancer ever conducted.
@@Molon_Labe1776 yep and that's just the tip of the ice berg .Magnetic fields man made or natural can steer harmful particles towards a specific area where you don't want them to go same issues where people live where the Earth's field dips into the ground .and energetic particles get steered just like how a cathode ray tube works to deflect the electron beam
There are serious problems with that study (pmc.ncbi.nlm.nih.gov/articles/PMC4617228/) and more comprehensive studies have debunked that finding (www.nature.com/articles/s41416-018-0097-7)
The problem is that we do not know whether these children had amalgam dental fillings. Alternating electromagnetic fields can attack these metal-containing dental fillings electrolytically and thus be a permanent source of metal ions, e.g. mercury. Some mercury compounds are considered to be carcinogenic.
@JargonFootprint yes that is true amalmgum mixed with an electrolyte and being exposed to EMF RF and other forms of resonant energies at frequencies can cause all kinds of problems .The other issue is how magnetic field can steer high energy particles from space to a specific direction based on the Earth's flux lines and locations of power distribution systems .Too many things to calculate but if you know both directions velocity and energy you can predict the direction of the focused energy .Just like in a CRT electrons are steered by the yoke .the same way ground plains steer RF and multiply power and direct it .
Why do you keep touching yourself with those wires?
It’s called “shtick”.
☠️☠️☠️☠️
Stimulation
@@MonkeyNeuronActivation To feel the to tingle?
Your body needs electrolytes.
3:04.... yet 😆
On a related note, when I was in highschool, I wore a thick polyesther coat in the winter as well as boots with rubber soles. If I made the mistake of taking my coat off before removing my earbuds, I'd get a static charge right into my ear canals
9:10 please tell me what is the phenomena behind this why high voltage current flows through you even when you are standing On non conductive material? For example why touching live wire with pvc pipe won't electrocute while standing On pvc flooring and touching live wire with bare hand Will electrocute?
5:21 ohhhhhhhhh..... so thats why there were rumors like this at 2018
