The cage itself will have a (voltage) potential from one location to another (on the cage), which is why inside the cage is electrically silent. The carboard is an insulator between the goods you want to protect, and the conductive cage.
Grounding the cage is unnecessary.
” I do think it makes sense to have rechargeable batteries, a solar system to provide some basic recharge system, a solar water pump, etc.”
Solar cells are huge semiconductors with a P/N junction similar to a diode and would be the first thing to go if they were on your roof.
“space blanket.”
I might start buying them again just for this.
They make lousy blankets.
My 67 Chevy should still run, but of course all the gas pumps are now fully electronic so I’m still hosed....
“What I don’t understand is the logic of trying to protect a generator that will require fuel which will quickly become unavailable following any event that takes out major power distribution facilities, transformers, etc.”
If it’s a diesel generator, then you can probably run it on biodiesel, or even ethanol, that you could produce yourself. That will probably lessen the lifetime of the generator, but it’s better than no power at all.
We have a 4 drawer metal filing cabinet which we plan to use as a faraday cage. It will work just fine as will a metal 30 gallon trash can. Also if your car is in the garage and you ground it with a piece of chain or something hanging off the bumper chances are it will start again after an EMP.
Conduit comes in aluminum, steel (RGS), and plastic.
The Faraday cage works on the principal (discovered by Faraday), that an electric field inside of a conductor will always be zero because the electrons inside the metal always move in such a way as to always cancel the external field.
I realized after I posted that copper mesh is an effective Faraday cage, so the magnetic field alone must not be an issue. Thanks for information.
“I dont think so- I think Aluminum is a good conductor”
Aluminum foil acts as a farday cage. Ex: Turn off your cell phone and wrap it in aluminum foil and it will survive an EMP. Paper a closet with aluminum foil top to bottom and it becomes a faraday cage.
We have had three EMP solar strikes since the late 1800’s. Cover your gen’s with foil. Try using the original box, if possible. Use tape to secure the edges. Learn to protect your fuel source, by being a bit smart. Energy will be your main concern- after water storage and food storage. Get the clue. It is not that hard to prep, just a bit.
“The bomb releases a magnetic pulse that is NOT electrical.”
This is not correct. EMP stands for electro magnetic pulse. Electric pulses do not propagate by themselves and neither do magnetic pulses. Combined, the wave travels at the speed of light in a vacuum. Spark a wire across a battery and you will hear it on an AM radio. That’s the kind of pulse were talking about, only millions of time larger.

How about my Airstream travel trailer?
You know, for an article that purports to be authoritative, it has the wrong units for electric field. It makes you wonder what else is wrong. Probably a lot.
It's volts per meter, not volts per square area.
I suspect these people are just copying and pasting stuff, and know nothing about actual RF engineering. This is my field.
This is not even coherent enough to be wrong. It is virtually meaningless, like something sent repeatedly through "Google Translate."
Regards,
I suspect the roll-type radiant barrier material would help protect electronic gear inside houses, too - at least the stuff that's not plugged-in to power outlets or antennas. I know it'll block RF well enough to silence an attic-mounted shortwave antenna.
We put a motorola reserve charge/battery pack for my kids tablets in our tornado room and it allows the kids to play their games (and remain calm) when the power is out. Have had to use it once and am glad we had it.
Entertainment for kids is often overlooked.
My problem is that even if I prep well, I am dependent on hormone replacement drugs to live due to cancer surgery. My life expectancy is about 30 days after I take the last pill. Unfortunately the government will not permit me to obtain more than a 30 day supply on a refill because this medicine is abused by trainers and athletes. Therefore, if we have an EMP attack, and services are not restored quickly (which they won’t be), I’ll certainly be a casualty.
You don’t know what you’re talking about.
You haven’t built a ‘Faraday cage’. You have built a shielded enclosure.

I had a solar panel to provide trickle charge to my boat battery. Lighting strike caused diod to blow and actually melted leads where they connected. No other damage to electrical systems. Always wondered if the charge from the strike did it, or if the flash was so bright it generated a spike of current from the panel that caused it. Replaced the diod and all was well.
If I had panels for SHTF, I think I would try to protect them and not mount them till after the event.
