Thus, with the current number of smart fortwos on the road, we may have to go 10 to 30 years before someone gets struck in their smart car. I have seen cars struck by lightning that had only a small burn mark on the roof and were otherwise fine. By the way, you have a better chance of being killed by a drunk driver than being killed by lighting.
But what are the proper dimensions of a faraday cage capable of being effective during a nuclear holocaust?!
Well the classic wisdom is that it requires antennae or something similar for the EMP pulse to enter through. But of course, as power plants would be prime targets, along with major transformer centres, people would lack electricity very quickly. With thunderstorms and lightning breaking the Great British Heatwave, which saw the hottest day for seven years recorded - we take a look at how to stay safe during a such weather. The weather map on the left reveals where the rain has been falling across the UK this morning while the map on the right shows where the highest number of lightning strikes have been. The reason you're protected in a car during a lightning storm is actually because the car acts like a faraday cage. A complete metal shield is necessary for full protection - so if you're stranded during a lightning storm, take cover inside a car with the windows wound up.
Fibreglass bodied cars are not safe as the outside body needs to be conductive to form a Faraday cage and fibreglass is an insulator. Door and window handles, radio dials, CB microphones, steering wheels, and other inside-to-outside metal objects should be left alone during close-in lightning events. The USA's National Lightning Safety Institute also recommends pulling off to the side of the road in a safe manner, turning on the hazard lights, turning off the engine, putting your hands in your lap, and waiting out the storm. Recently the The Top Gear team created an experiment to find out what it would be like if you were struck by lightning while in your car.

On October 8th, 2012, magician David Blaine performed a seemingly life-threatening stunt subjecting himself to a whopping one million volts of electricity while wearing a 20-pound chain metal suit.
The public was shocked by the performance, a demonstration that seems to defy the basic laws of science.
In the video of Blaine’s performance shown above, the magician is wearing a Faraday Cage – a type of suit made of a conductive material invented in 1836 by English scientist, Michael Faraday.
So while Blaine’s performance looks pretty dangerous, his Faraday Cage (which, theoretically, has no voltage limit) prevents the electric current from reaching his body, making it not quite the superhuman feat it appears.
Elevators simulate a Faraday cage effect, leading to a loss of signal and "dead zones" for users of cellular phones & radios which require electromagnetic external signals. The shielding inside of coaxial television cable wire & USB cables protect the internal conductors from external electrical noise and prevents the RF signals from leaking out.
Plastic bags impregnated with metal are included with highway electronic toll collection devices which are to allow motorists to place them in the bag so that a toll charge is not registered or a device will not register a charge while being shipped to a customer's home after ordering in a delivery truck. Even MRI machine scan rooms are designed as Faraday cages to prevent external radio frequency signals from being added to data collected from the patient, which would affect the resulting image. Shopping bags lined with aluminum foil have even been found by police in arresting shoplifters who steal RF-tagged items; the bags acting as Faraday cages. In the caption for the piture included with this article, it states, "the public was shocked by the performance, a demonstration that seems to define the basic laws of science." I think the word you should have used here in place of define is "defy". The physics of the Faraday cage fully protects David from the electric discharges, but I'd have to ask about the chemistry of the experiment. By wearing a Faraday cage-type suit, the danger to him is extremely small, especially when many electrical linemen routinely working on Kazakhstan's 1.15 million volt Ekibastuz-Kokshetau electrical line wear such a suit with regularity. The room was ventilated of harmful ozone and nitrogen dioxide created by electricity ionized air. Arbor Scientific is a leading provider of Physics and Physical Science teaching equipment tested and approved by educators recognized for their expertise.
It's a common statement that passengers of a car are protected from lightening while inside because the car has rubber tires (which are insulators). If you add anything to the vehicle, like external antennas, radios, etc., then all bets are off.
However, the metal shell of a car provides a pathway for the lightning strike to flow around the vehicle provided the car has a hardtop metal roof (not a convertible). For the same reason, you don't get electrocuted when lightning strikes your car (provided your car is made of metal and not fiberglass, you don't have a cloth convertible roof, and you're not touching the outside surface).
None of the 500 people on board the Emirates Airlines Airbus A380 were injured as the plane flew through a storm as it approached London's Heathrow Airport on April 23 2011.
A United Emirates spokesperson told the newspaper lightning strikes are not uncommon and that every plane in its fleet is designed and certified to withstand a lightning strike. Passengers inside a steel bodied car are protected from lightning because the car behaves like a 'Faraday Cage'. Well, the tyres are made of vulcanized rubber and the black stuff in them is carbon that does conduct electricity, as do the steel belts inside the tyre.


Pneumatic tires which contain carbon black generally have a resistance of approximately 10^6 ohms, measured from the crown to the bead. Pneumatic tires which do not contain carbon black do not satisfy this test; their electrical leakage resistance is approximately 10^10 ohms.
Generally we do not use air or any other gasses to conduct electricity and, for the sums, air is considered to be of infinite resistance. Being a cheeky so-and-so Mr Lightning would dearly like to zap the hamster in the car, however, no matter how hard he tries he just cannot ionize the air inside the car in the way that he has been used to to so far. It is the Faraday cage of the car that protects the occupant, a wrap-around lightning conductor that works very well so long as it is made of a metal.
Technically the electric current takes EVERY path available but splits accordantly after the electrical resistance. And, as Hammond commented in the video, if the lightning can conduct from sky to car, there's little to stop it conducting from car to ground.

Is there a simple way to convert a unique string of characters into a unique number in JavaScript?
Trying to predict what a lightning strike will do to a car is like trying to predict how many grains of sand will be stuck to your feet after you walk on the beach.
Some are struck on the radio antenna and some, but not all, the electronic modules in the car were toasted.
It also points out the futility of making all-encompassing blanket statements about anything.

Until your account has "passed" your posts will only be visible to yourself (and moderators) until they are approved. Either the bomb goes off close enough that the EMP will override pretty much everything, in which case the blast (pressure wave) or the fire storm will kill you. In addition, cars aren't really made out of metal any longer, at least not uniformly enough so that it would protect you. If you happen to find a design that calls for the use of wire mesh instead of solid metal, be sure to get some with the smallest holes you can find.
After the fall of Akhenaton their descendants eventually emigrated to their ancestral homes in the West in order to establish a new empire. H-Bomb directly above Paris would kill most electric equipment in that city but what does it matter when most people would die immediately from the blast or shortly from radiation? Not a problem if you can heat your house through a fireplace or two and have a working well in the front yard. The Met Office has issued a Yellow National Severe Weather Warning for thunderstorms and long spells of thundery rain across the UK today and tomorrow. Contrary to popular belief, the reason for this isn't because cars have rubber tyres which insulate you from the ground.
After all, lightning has traveled for miles through the sky: four or five inches of rubber is no insulation whatsoever.
Anything inside the conducting object (the cage) will be protected from the external electrical current. Richard Hammond was hit by 600,000 volts of nature’s finest whilst sitting in a Volkswagen Golf. However, an understanding of the laws of electricity will show that Blaine was not working against these basic principles, but was using them in order to perform his trick successfully! The suit functions as a shield that blocks external static and non-static electric fields which causes the electric charges within the Cage’s conductive material to redistribute themselves and thus cancel the field’s effects in the cage interior.
Nevertheless, showing this video to your physics classes will have even the bravest students on the edge of their seats – until you explain the principles behind it!
Their suits prevent electrical current from flowing through their bodies and the suits have theoretically no voltage limit. The lightning strike between the cloud and the ground has potentially traveled thousands of meters through thin air, therefore rubber soled footwear or tires are inconsequential. Although such vehicles do not offer you absolute protection from lightning, you and others are much safer inside a car with your hands on your lap, than outside.
When lighting hits the car it wants to take the shortest path with the least resistance to ground. There is a provisional specification for this measurement, this being laid down in the WDK guideline 110.


But, where there is a will there is a way and, if you place a big enough potential difference across air it will conduct.
Well, he knows he can ionize air as he has already done quite a lot of that already making his way through loads of sky. Not because the air conditioning is off, but he cannot get the required potential difference, what with that tin box conducting so readily. Otherwise a good answer, so I won't let that piece of lazy research stop me from up-voting. Sometimes the strike will short the diodes in the alternator or melt wiring or fuse links. Looks like solar flares aren't anything to worry about, if your back up drives are not connected to a power source. From Britain they exercised control over their many lieutenants in Athens, Rome, Tanis, Alexandria, Judea, and elsewhere.
The Chief Forecaster's statement describes thunderstorms continuing to move north across England and Scotland, with some very energetic storms producing frequent lightning. The same holds true for lightning when it strikes metal vehicles - the outer surface carries most of the electricity. It seems that Blaine has had excellent advice from his handlers who apparently have had some basic Physics! The driver suffered minor injuries despite being in the truck, as it hit his CB radio antenna. According to this a pneumatic tire belongs to "electrostatically active Class I" if it has a leakage resistance of less than 10^6 ohms.
When this happens the little electrons in the air get scared and do a runner from the nuclei that they have been bonded to in a process called ionization. However, as he gets to the ground he wants to be lazy and discharge his electrical load as easily as he can.
This is likely because the high EM field interferes with the electronics, so it is not guaranteed that the car will survive this. Seems nobody bothered to look up ionization of air or the electrical resistance of tyres, or take the three years to do a degree in Physics. Because the tires contain carbon they will conduct if the voltage potential is high enough, and I have seen tires blown out by a lightning strike. Once you have passed the moderation period (think of it as a test), you will be able to post normally, just like all the other retards. At least all our mobile C4I stuff was built so they could be grounded, always through two or three poles. The British Empire is unquestionably the Atonist empire upon which the sun (Aton) never sets. Consider also that majority of food is stocked in huge distribution centres before brought to supermarkets and grocery stores - those going sky high would imply starvation for the civilians in short order, unless the State has the foresight of stockpiling rations.
Faraday cages are named after the English scientist Michael Faraday, who invented them in 1836. A famous East German car the Trabant was called Pappe(cardboard) in German because of its exterior but was still safe(metal frame). Spotting a car in his path he thinks 'I will go and hit that rather than the nearby ground as that is closer and less effort'. They have to conduct electricity to prevent static build-up in the car and there are standards in place to make sure that they do not have too high a resistance, even if they do not have 'carbon black' used in their manufacture. Anyway, as long you don't touch the ceiling there is not much reason for the current to go to the seat and your legs. One car even had some electronic modules fried and it was parked next to a pole that was struck but the car was not struck directly. Similarly all the doors were always kept shut, so that the metal frame forms the Faraday cage.
Our work is dedicated to the exposure of these psychopathic plutocrats and the ruin of their antihuman industry. Of course, plenty of population would be killed in short order through strikes in major population centres, so that would somewhat alleviate the food problem. Until this Black Lodge is correctly identified and destroyed, common or garden political activity and civic reform will prove ineffectual. Still, it has been estimated that Britain, for example, would in few years have a Medieval level of population if tractors, pesticides and food imports would all suddenly disappear - as they would during a nuclear war. The carbon-black tyres are planted on the ground and, although not exactly as easy a ride as copper would be, he does the maths (10000000 ohms resistance is better than infinite) so he goes that way.
