hey um couldnt you induce a short wave length emp by putting oh say a pipe wrench or somthing conductable between two transformers and also would it be effective enough to take out a grid from shorts in th electric system in a big city for atleast a minute before it is back up
in the whole city? that has to be one hell of a power source....
To make an EMP with AC currant I think you need a single loop antenna and I don't think a pipe wrench would do? To take out the power supply to a city even a small one you would have to take a hole switching station off line. Even this would most likely be isolated to a small aria depending on how many stations there are and probably last under a minute or two. Taking out a transformer would only affect the users down line. Maybe a block or so. This to may only last for a short time depending on were it is in the system. All of this is highly illegal and very very dangerous
You guys could both be incorrect about a car being a Faraday Cage. It very much depeds on the wavelength of the radiation - a Faraday Cage needs to have perforations smaller in size than the wavelength of the radiation you are defending against.

If you read carefully that has already been stated.

There is just to many variable's to argue for or against this . Size of the bomb,elevation of the detonation, Type of weapon single stage or two stage. The magnetic field over a given aria .Also the lack of information that the variables above have on the wavelengths produced.
I know that GFCI (Ground Fault Interupt Circuits) work great when they detect high voltages (typically from water in the outlet or in highly humid environments) and immediately cut the connection to AC voltage. Does this type of technology not work with EMF situations? Why or why not? I have been doing research that says that no inside-to-outside connection from an EMF-proof room can be established. Why can someone not have some sort of solar or wind-powered units set up with electronic connections to an establishment that has been "basically" EMP-proofed with thick concrete and interlaced copper-mesh wiring, and still have problems with EMF emissions? By the way, I understand that those "outside" solar or wind devices might be completely spoiled in this event. I'm more worried about protecting those devices housed within the "safe area". Can't there be some type of massive surge-protecting device installed between the outside and inside electronics? Thanks in advance for all input.

If by "electronic connections" you mean a hard wired connection, than yeah, you could possibly have a link, but, as you mentioned, the "outside" electronics would be affected/disabled as well.
The problem with surge protection is that an intense E&M spike would generate massive spikes of current in closed loops of conductors and it's very hard to ensure that all such loops are broken/protected in most electronic devices.
I have created a blog meant to inform ALL Americans on the threats of E.M.P. and other catastrophic disasters. I go in depth about an E.M.P. Scenario and what would happen to us if we were to be hit with one. Please visit my site at ultimatepreparedness.wordpress.com. I even have a video (or at least a link to it) of an actual E.M.P. wave hitting a car and showing what would happen to it.
Also, I remembered that discovery did a program with a section on it, in 2006 as part of the series 'Future Weapons'.
I saw that program too. The car shut right off. They weren't trying to simulate a high altitude nuclear detonation, though, so we can't know if the energies put into the car exceeded those you'd expect from an emp but it certainly shows the vulnerabilities of modern cars. Modern cars won't work without their motherboards, but it's not like the engines will seize. If an EMP attack happened that didn't turn into full scale nuclear war, it's not like you'd have to buy a new car but you would have to wait for your local mechanic to get done fixing everyone else's car before yours, so it would be a pretty big deal. I think we'd start to rebuild all our stuff with insulation in mind which might actually help the economy in the long run. An EMP attack on the US would probably hurt more than the other guy's economy, too, in the end.
