Could a nuclear generated electromagnetic pulse kill your car?
http://www.electropages.com/2017/05/cou ... -kill-car/

Published May 22 2017

Most of us know about the latest round of sabre-rattling, chest-thumping verbal exchanges between the USA and North Korea as they strive to convince each other their military weapons are biggest and best. Its familiar stuff, except for just recently when the subject of nuclear generated electromagnetic pulses reared its potentially devastating head.

Electromagnetic pulses (EMP) as a form of military weapon have of course been known about for years although information about them has been closely guarded.

An enemy could use EMP to destroy the electrical and electronic infrastructure of another country with massively debilitating effect. Anything from communications systems, power grids, electronic equipment, water and fuel services and much more could be disabled by an EMP attack.

However one element of modern life that may possibly withstand such an attack are the cars we drive.

But before delving into that, what is an EMP? The most familiar one to most of us is a lightening strike which in EMP parlance is classified as an E2 strike. Potentially very dangerous but usually controlled by surge protection technology so damage is minimised.

Nuclear generated EMP

In comparison to lightening, an EMP created by a high altitude nuclear device has the higher classification of E1 and is far more powerful.

Following such a nuclear detonation, gamma rays are released that start to absorb electrons from the atmosphere and both of these head towards earth. This is called the Compton Effect and the electrons combine with Earth’s electromagnetic field to generate extremely powerful magnetic waves.

The nuclear device prompting all this doesn’t need to be that big. In the early 1960s the USA tested a 1.5-megaton nuclear EMP in a study referred to as Starfish Prime above the Pacific Ocean. It caused electrical damage 900 miles away in Hawaii by disabling about 3% of the island’s street lighting.

However, if that same warhead had been exploded 200 miles above the US mainland the damage would have been far more. The strength of that EMP would have been up to 30,000Volts/metre because the Earth’s magnetic field has greater strength over the United States territory rather than the Pacific Ocean. And while on the subject of EMP strength, scientists today estimate that in the right location an E1 EMP could be as powerful as 50,000Volts/metre.

Wrecked Infrastructure

So having wrecked a substantial amount of what is considered modern infrastructure would a nuclear EMP attack also disable our cars? This is a tricky question to answer because even today the effects of a true nuclear EMP are difficult to accurately predict.

At the time of the Starfish Prime test cars were much simpler technically than today’s vehicles and the generally held view at that time was cars might stall but would probably start up and run normally.

Today opinions on the subject vary enormously. One view is that if your car has electronic fuel injection, anything computerised that controls your vehicle’s primary systems, a powertrain control module, ABS, electronic ignition or keyless ignition then your vehicle would be totally disabled by an E1 EMP of 50,000Volts/metre.

Sensitive Electronics

However, opposing that somewhat negative perspective is the view that many vehicles might survive an E1 EMP. Sensitive electronics may be shielded well enough to continue to operate. In effect, the metal parts of a car body could potentially act as a Faraday cage. And lets not forget that many electronic components used in cars have to operate in harsh, high temperature conditions and consequently are often of more robust design and are well protected.

However, the Faraday cage optimism is somewhat dented by the fact that if a car body did form a perfect cage then you wouldn’t be able to make phone calls from it.

Generally speaking the answer to whether our modern cars could stand up to an Electromagnetic Pulse attack comes down to just one thing; how strong is the attack.

Tests in the past have shown that car electronics subjected to an EMP of less than 25,000Volts/metre would not be effected. It is only when an EMP of E1 proportions (50kVm) strikes that serious problems could occur that would either totally disable the car or cause malfunctions on a car that was being driven that would inevitably result in a road traffic accident.

Tests have also shown that cars switched off at the time of a high power EMP would start and function close to normal.

So some drivers could find their cars were still working following a substantial EMP attack. The question is would they still be useful bearing in mind fuel would not be available because the electronics used in garage petrol pumps would be disabled and highway control systems such as traffic lights would be out. Add to that the fact highways would be jammed with dead cars and perhaps the overall answer to the headline question is don’t throw your bicycle away yet.

My understanding, is that they are still not sure. The one test done was grossly underfunded. They used rental cars and vehicles borrowed from other gov. agencies. Those cars had to be returned, in the condition they were received in. As soon as it looked like the emp generator was effecting the vehicles, they terminated the test.

Just in case, I'd plan on an alternate way to get home from work.

all the EMP studies have been conducted with intensity EMP emissions lower than what is actually expected by the military - specifically designed EMP weapons scaled to overcome the shieldings is expected - the civilian stuff is simply going to melt ....

NORAD moved back into Cheyenne Mountain solely for the EMP threat - spent billions $$$$$ on upgrading the protection - they know what is coming ....

ReadyMom: That was an excellent restatement of the EMP situation. Thanks.

This is a report I ran across last year. However one can never be certain what to believe.

Do you have a cite for either of those assertions?

Both were also political movements with a religious component, just like Islam.

Actually the EMP has three components E1, E2 & E3 and hostile military forces are/have developed a super EMP that may run as high as 200,000 volts/meter. I would think that anything that has a computer chip in it would be toast unless protected by a very robust Faraday cage.

Yeah, the main one most preppers need to worry about is that E1.
The E2 component is just like lightning, and I have already been inside of a lightning bolt because of my job a couple of years ago, so that doesn't intimidate me too much. Anything that interconnected by any kind of conductor to the outside world will be subject to the E2 and E3 components, and I don't give those things more than a snowball's chances in hell of surviving.

As for the Super EMP device, well, there is always an alien battle cruiser
or a Korlian death ray or some ... oh, wait, wrong script :lol:

The limiting factor in the E1 component isn't the bomb itself (unless it is very small), it's the components of the atmosphere, so the only thing a Super EMP device can do is either allow them to use a smaller bomb, or increase the radius that the EMP will effect. I think the latter one is the real important one.

assertions? - just common knowledge from following nuke development since the 1970s and doing something with a computer besides playing a video game and beating off to porn - try to follow current military activity and you might learn something ....

if you haven't heard the latest "assertion" - NK is readying another missile test - this one from a sub ....

OK, then that would be a "no." While you were following it, I was doing it.
But that was a generation ago, and I thought you might have something besides an urban legend.
Sorry to bother you.

Yep. Know all about it. Don't care.
That isn't the threat that will kill us, just a side show.

A point I'd like to raise is not the direct threat to vehicles (road, rail, waterway, and air) but the threat to the necessary supporting infrastructure. By which I mean if there is no electricity there is no gas or diesel available. Or at least not easily obtainable.

Also, by most accounts the communications infrastructure would be severely damaged. While this degrades radio/television, don't forget the high tech electronic computer driven systems that track fuel consumption and order re-supply. Basically, if the electronic systems to pump POL to and within U.S. regions goes down, there will be no fuel coming other than what's in your tank or the local gas stations if they haven't been destroyed or taken over my local militia.

In the end, should vehicles not be effected, this might lead to a faster ramp-up to greater social violence than if they were completely knocked out of commission. In other words, if my family's life depends on my taking your vehicle's fuel, whether you want to give it up or not becomes moot. Not saying I would do that, but how many normal citizens across the nation who never thought about anything like this, suddenly find themselves thrown into the grinder?

I consider this to be one of the most important factors regards bug out. For not only do you have to be concerned with having enough fuel to reach your destination - you have to worry about thousands of other people local to your present location all viewing your vehicle as the single most important source to save their families.

To this end, I have always liked the one scene in the Tom Cruise "War of the Worlds" film. The one where he went to sleep while his teenage son drove their minivan right into the middle of several thousand refugees all desperate to get the hell out of dodge. The fact Tom's vehicle was the only moving means of transportation led immediately to mass attack on it, the resulting gun fire first deciding who controlled it, but eventually the current driver only had so much ammo and there were so many targets he/she could not keep from getting killed and the next volunteer grabbed the wheel. Only to have the process repeat itself as the minivan was driven out of sight.

A very extreme example to be sure, but one not too far off target to imagine what would happen if you had the only moving vehicle within site/sound and everybody starts lookin at you.

Just sayin.
