I've always heard people say that an EMP from a nuke may cause more damage then the nuke itself. It frys anything electronic. I've also heard that you can increase the potential for an EMP by having it detonate high in the atmosphere. My question is, can an EMP really take out an entire city, or more? If so, how far could it reach, what would it effect, what wouldnt it effect? Would peoples cars die out, phonelines, flashlights? etc.
How much damage would it do, and would it really bring us to the stone age?
The pulse can easily span continent-sized areas, and this radiation can affect systems on land, sea, and air. The first recorded EMP incident accompanied a high-altitude nuclear test over the South Pacific and resulted in power system failures as far away as Hawaii. A large device detonated at 400�500 km over Kansas would affect all of CONUS. The signal from such an event extends to the visual horizon as seen from the burst point.

Has there ever been a high altitude EMP test over land?
An explosion over a huge body of water like the pacific would effect any land mass near by.
There is know way a single explosion over the United states would kill all of the power. I dont care what the scientific data says, they have never tested an EMP directly over the united states.
There for they dont know.

I think we have to look at two cases of EMP:
Nuclear and Conventional.
The conventional method utilizes explosive flux compression generators for the creation of a short pulsed strong electromagnetic field. Only electrons should be involved in this case.
"But I'm not aware that the Americans have perfected any electrically-driven e-bomb technology," he said.
"They have gone down the conventional explosive path because that's quicker and easier to do."
Electrically-powered versions need a very high voltage to generate the microwave output.
Researchers say the problem is not only generating that but controlling it and the associated heat that is produced.
But Dr Davis says the Russians have done a lot of work on such weapons and he has seen a photo of an electrically-driven, shoulder-held microwave weapon - resembling a portable SAM anti-aircraft missile launcher.
It was claimed this could knock down an aircraft up to eight kilometres away.
These claims could be exaggerated, he said - but there was no reason technically why you could not generate a pulse of electromagnetic energy in a particular direction.
As long ago as 1998, a Swedish newspaper reported that its country's military had bought and tested a Russian HPM bomb.
The briefcase-sized device was said to emit short, high-energy pulses reaching 10 gigawatts - equivalent to the output from 10 nuclear reactors.
The German company Rheinmetall Weapons and Munitions has also been researching e-weapons for years and has test versions.
It is reported to be collaborating with Russian institutions in developing an HPM generator that could be fitted into a 155mm artillery shell.
The head of US defence company Raytheon Electronic System's directed energy programmes has predicted that there will be HPM weapons within five years.
A thorough study of the subject recently published by American think-tank the Lexington Institute concludes that such weapons will revolutionise warfare - but not just yet.
"Within the next few years, the first weapons systems built with directed-energy as their kill mechanism will be deployed," it says.

Electronic Bomb Tested In Sweden
January 23, 1998
STOCKHOLM (AFP) - The Swedish military has bought and tested a Russian electronic bomb using high-power microwave signals to knock out the computers of jet fighters and nuclear power plants, the Swedish daily Svenska Dagbladet reported Wednesday.
"Russia is among the best in the world when it comes to manufacturing this type of electronic weapon," said Anders Kallenaas of the Swedish National Defence's Research Institute (FOA).
The high-power microwave (HPM) bomb is stored in a briefcase and emits short, high-energy pulses reaching 10 gigawatts -- equal to 10 nuclear reactors.
It has a range of a dozen meters, and larger models stored in vans can reach as far as a few hundred meters, according to the paper. The target can be destroyed without alerting anyone.
The tests conducted by the Swedish military have shown that the silent weapon -- which does not explode -- can have disastrous effects, especially if it falls into the hands of terrorists.
The HPM bomb can be bought on the Russian market for "several hundreds of thousands kronor" (less than 100,000 dollars) and has already been bought by the Australian military among others, Svenska Dagbladet said.
The bomb presents a threat to the Swedish military, in particular to the JAS 39 Gripen jet fighter that it is trying to export. It can also knock out the electronic systems of nuclear or electric power plants, banks, trains, or even a simple telephone switchboard.
The bomb has also been developed into a pistol which can be used to knock out a single computer or vehicle.
The Swedish military has reportedly considered employing trained hackers to combat the problems posed by the new technology, though this could have legal implications.
The soviets wanted to use Neutron bombs once to disable the electronics of western bomber fleets (If I remember it correctly).

Now, I'll be the first to say I'm not up to speed with the full extent of emps. But from what I understand it has the power to overcharge any power supply, and basically use that to fry the electriconic equipment. This means your cars electronics would die out, smaller electronics, televisions, phonelines, but also, it will most likely cause power generators and electricity producing facilities to overload and possibly explode. So the lights WONT come back on, because the thing that was producing power is no longer available.

Which is why the estimate is 300 miles over Kansas to take out the entire United States.

What a lovely thought. Thanks for sharing.
Although, as powerful as it might be, the pulse would be anywhere from local to medium ranged, at the very best of its efficacy. Sure power supplies go down, but the infrastructure, larger power lines, switching equipment and such, would be able to recover or be repaired.
How do they fix areas struck by hurricane? Tornado? Lightning storms?
