RTewell is right... a balloon would work. That is a threat to the U.S. West Coast especially, since the upper level winds would carry the balloon the right direction. To use a balloon for the East Coast, you would need to launch from the Midwest. (This assumes that terrorists would not want to risk having the balloon stay aloft long enough to float across the country.) In fact, the US has already done high altitude nuclear tests using balloon-launched bombs. The problem when discussing the EMP threat is that it sounds too much like science fiction. People ignore the threat, thinking it is only as real as the Star Wars Death Star. Take, for example, NBC's new TV show "Revolution." The "EMP" in Revolution isn't a real EMP.... it is fictional. Revolution's "EMP" shuts off all power *worldwide* and seems to *block* power completely, unless you have a secret device. That's fictional, not real. A real EMP would knock out the power grid in areas under the blast, but would not block electricity. We've created a YouTube video that compares Revolution's EMP vs. the real threat. It shows photos of the power grid equipment that could be destroyed by a real EMP. (The video is at www.youtube.com/watch?v=rWd93u-Xi8Y). I hope you'll watch it. It will let you respond with facts and specifics when someone tells you that this is all made up. It offers specifics that will let you evaluate the threat from an EE perspective. We also have an EMP simulator on our site, EMPCover.com. EE folks will be interested in seeing the energy pattern, which is not uniform. It is much easier to understand if you look at the graphics.

Sylvie, No to belittle this threat, but I am among the skeptics that think this issue has been over blown, not to the same level as Y2K but if you think on the basic electromagnetic properties of such weapon. That such pulse effects decay at the square root ratio from the distance of impact. So unless many weapons are deployed at all mayor urban areas, at all critical power plant sites and industrial sites. The threat is regional in nature. No dooms day scenario, USA has an advantage over European and Asian countries where the population densities are greater, most people would survive, it would some losses but most people would overcome such tragedy. America will endure.

No need to use a rocket. Weather balloons work just fine. You only need to get to between 30 and 50 kilometers (easy peasy for a weather balloon). Dude on Sunday flew to 39km in a helium balloon and jumped out. Another guy, took off with weather balloons in a lawn chair. No way to police or stop it. In fact, a weather balloon with some sort of very easily accessible "drone" technology (electric motors) to allow it to be "steered" - would be ideal. Could likely be done with R/C parts and a couple of iPhones. Might be a fun experiment...hmmmm... Not the EM pulse part...but the steerable weather balloon part.

A dangerous idea.But going into space and doing this is not so easy with the present tight rules and regulations of flying things into the space.

Probably a circuit with some form of shunt capacitance. I believe Government and energy firms are taking this threat more seriously nowadays.

can anyone explain about geomagnetically induced current blockers

I think that en mass, people tend to not truly recognize dangers or threats until a significant even happens to demonstrate that threat. On an individual level, there are plenty of people that can recognize threats, which is why we have articles and studies. But it's the masses that approve funding and or demand action.
