EMPs!!! You know, the big electronics-frying pulses that accompany nuclear blasts. We’re back to worrying about them again. In particular how does the military protect its electrical infrastructure from an EMP attack.
“Yeah, we have issues there [with the EMP threat] and we have to look at those and we seriously have to understand that in the Army in particular, because we have an awful lot of bases that we look at,” said Marilyn Freeman assistant secretary of the Army for research and technology during a House Armed Services emerging threats subcomittee hearing today. “I work very closely and the folks in my office and accross the laboratory system of the Army work very close with the installations folks as we assess what our vulnerabilities are to power and energy issues and one of the things we’re trying to do is actually set up the ability for our various bases to be more energy self sufficient, more energy secure and to have the ability, not only to be more efficient and effective, but also to be safe and not vulnerable” to attacks from EMPs that would shut down a bases power systems.
If you think it’s easy to harden a base connected to the civilian power grid from an EMP blast, think again, one of Freeman’s fellow Pentagon science officials said in when a lawmaker asked how soon the nation can protect its bases and power infrastructure from EMP attack.

Just put a really big Faraday cage over the US. Problem solved.
Well my FRiend, you need to choose between educating yourself from source documents or listening to idiots like this “contact” of yours who doesn’t know what he’s talking about.
I suggest education, but YMMV.
Some people just like to make snippy comments on the topic of EMP because either they flunked science (or reading) or because they think it’s cute somehow.
If you’d like some facts, here is a report from the British House of Commons that was released just this year:

Like Fox News says, “We report, you decide”. But facts are handy things.
I can and have built crystal radios with a chunk of galena, an empty cigarette pack, a sheet of newspaper, a toilet paper roll and a bunch of wire.
It's good for cooks to know the basics of technology, and how to build them from scratch. You just never know what might happen in a commercial kitchen.

Does anyone know whether or not the aircraft that dropped the A-bombs on Hiroshima and Nagasaki were damaged by EMP?
They condenser is the key - most likely to fry, hard to replace.
OBTW, you have listed the makings for the threat ...
The B-29 aircraft that delivered the nuclear weapons at Hiroshima and Nagasaki did not lose power due to damage to their electrical or electronic systems. This is simply because electrons (ejected from the air by gamma rays) are stopped quickly in normal air for bursts below roughly 10 km (about 6 miles), so they do not get a chance to be significantly deflected by the Earth’s magnetic field
You are older than you look.
If bombs had been within the intense nuclear radiation zone when the bombs exploded over those cities, then they would have suffered effects from the charge separation (radial) EMP
Unless one is expecting to get a pulse every freakin day or sumfin, replacement capacitors can be home rolled with wax paper and aluminum foil. In a circuit they can be protected with back to back Zener diodes rated higher than operating voltage but lower than maximum withstanding voltage.
Cat whisker on galena can work, but it is a pain. Better to have a stock of diodes kept wrapped in foil or something.
“Because the geeks at NOAA say it’s in a decline based on their measurements. NASA is aware of, and adjusts for a particular spot east of South America.”
Earth’s MAGNETIC field always changes.
And the spot off South America is the SAA, it has to do with trapped solar particles.
Neither have anything to do with EMP caused by a nuke.
Smartass. ;)

Ya know, the Amish might have an unexpected advantage.
They were not. Radios and radars intact. Same is true for the planes that dropped bombs for tests.
But- these were low altitude shots. You get source region EMP (SREMP) but no HEMP, High Altitude Electromagnetic Pulse.
Dude, I am going to need you in my bug-out location...
LOL.
“e aircraft that dropped the A-bombs on Hiroshima and Nagasaki were damaged by EMP?”
I don’t think that these aircraft had any computers on board to worry about.
LOL, I thought that might be the case.
I'm not particularly worried about EMP from nukes. But our feral gooberment takes it seriously enough to spend billions of our tax dollars preparing for it.

It’s been how long since an above surface nuclear bomb was tested? Those sites would be ideal places to research the effects of associated EMP. But the environmentalists would be way too agog now.
