Exactly.

And no EMP related downtime at all, for our appliances and such.

Speaking of EMPs.

If I had any, would my primers 'splode inside the factory packaging while stored in a plastic toolbox?

and our grid is in now way, shape, or form secure. Find a friend that works in that field and ask them.

I like it, the only problem is the generator is stationary and installed on a concrete slab, no way to get the mesh under it. Ideas? It will also run on propane, just have to change out the jet, (from what I've been told), they are finishing it up in the morning, I guess I'll ask them tomorrow. Thanks for all the ideas.

Will a faraday cage work on solar panels?

Yes, just cover them with some sheet metal and they'll be fine.

I'm not convinced that there is a lot of reason to go so far as building a faraday cage.

For a time, the prevailing theory was that if WW3 happened, it would start with a Russian nuke exploding 100 miles over Kansas City. That would indeed cripple US power distribution. One of our Pacific nuke tests took out the traffic lights in Honolulu.

The other threat is another Carrington Event. That was a coronal mass ejection that smacked into Earth and lit up the infant telegraph systems. One of those would also cripple US power distribution.

JMO, but if the generator is disconnected from the power lines, I think its chances of surviving either type of calamity are pretty good.

BTW, one way to make an antenna for a large aircraft is to cut a slit in the sheet metal. The slit acts just like a wire antenna in space. Think about what that means about being in a metal shed where sheets are not carefully bonded.

Oh, I got me an idea. Gotta run to PetSmart real quick before they close and pick up a hamster. What are they, like a buck-fifty or so?

Pop it on the microwave along with a tray of large pistol primers.

See if I can get my ass kicked off of YouTube.

While you're out, grab a roll of tinfoil.


Ask me how I know.

I have designed a lot of things with Faraday shields.

If you have the money [ uplinks for to satellites on AIR FORCE ONE, USAF jets, and USN submarines] you get MU-Metal
https://hollandshielding.com/Mu-Metal-Amorphous-Magnetic-shielding-materials
That can even sheild out low frequency. [important to the submarines]

If you are cheapskate [like one defibrillator in an injection moulded enclosure] you get conductive paint sprayed in the inside. The ground connection is touchy feely.


But mostly in the middle cost [F-16 radar warning, ect] you get a hogged out or investment cast Aluminum alloy enclosure.


For Halloween, you get an Aluminum foil hat.

Don't forget to put a Faraday cage around your house, so everything you want to use generator electricity for isn't fried by an EMP. smile

Clarkm,
Thank you for that write up, quit informative. Thought about it a lot last night, I could save the generator but there would not be much left in the house to use it for, now if we knew it would hit on say May the 21st, 2021, I could stuff the microwave, wrap the house in foil and wait it out, but since we don't know, I guess It's all just a mote point. And if the primers ignited, then the powder would ignite, then the ammo. I would not need to worry about a generator.

EMPs mainly effect electronics. Generally speaking, older less tech heavy items are less venerable

Doug, it’s my understanding that an overseas shipping container, with some modifications, will make a good Faraday Chamber! memtb

If you have to worry about an EMP shutting down your generator, you really have more important things to worry about. Make sure it is properly grounded and just keep up with whatever maintenance it may need. Enjoy the piece of mind of owning a back-up generator and just be on the look out for a decent buy on primers. The little stuff will take care of itself.

I have a secret security clearance for EMP threat levels, but I think I can say I do the exact same type of design fixes to protect from the conducted threat electronics boxes from 3 causes:
1) Static electricity
2) Lightning
3) EMP

Get well protected against lightning. That should be a commercially available option.

Understand what you are saying, trust me, I will never need to buy another primer, or powder, or bullets, or cases. or.....
My grand kids are set for life.
And the generator is well grounded.
