EMP Question

4x4 only is better than FWD when snow exceeds 8” on road surface and that happens like how often ?

It happened every winter that we were stuck with democrat governors in NH.

They had plenty of tax dollars for hiring hacks, but none for overtime for plowing at night.

I got stuck on my commute home on the south end of Franconia Notch in my VW Jetta turbo diesel.

Ergo the Grand Cherokee.

Now we have a Republican governor and I am retired from that commute.

so like 3 days a year ?

so like 3 days a year ?

Franconia, Kinsman, Crawford and Pinkham Notches get a LOT more snow from each storm than the lower elevations.

And then there is the drifting snow, depending on conditions for a few days after many storms.

So maybe 20 to 40 days a year, sometimes more.

Didn't want to eat up all my vacation days for that.

re: “It’s pretty juvenile to think being right or wrong means sacrificing national security.”

National security, or what ‘they’ want us to think it means, has long since screwed the pooch, before the sunset 09/10/01.
That was another gift of the Clinton crime family.

Deasrborn,

re: “You have no clue, and sadly, you have no clue you have no clue.”

Oh good ... I have the boatload of quarters already, so I don’t have to spend them on you.
Thank you, and have a nice day.

EMP PROTECTION DESIGN SPEC

I was Chief Engineer for a well known secret Military ‘product’.
My former boss was the top manager who built those Space Shuttles.

Engineering is about Best Practice.

Find the Maximum Hole Diameter for EMP protection by a Faraday Cage.
Best source is a Mil-Spec, military specification.

Double your protection:
Buy an old vehicle, electrical eg points, carburetor. Avoid all electronics. Car or motorbike.
Surround all 6 sides, like a box, with a chicken wire like cage. Includes top & bottom sides.
Critical spec is follow the Mil-Spec max hole size. Do not violate that. Any larger ‘hole’ defeats all.
Example: microwave oven hole size, front window screen, is tiny.

The enemy is insulating metallic oxidation along unsoldered seams like the door.
Store needed electronic/electrical gadgets, & vehicle inside.

Untestable, but that is top protection, nearly as good as the military,
better than 99.99% of civilians. Highly likely YOU will have survivable transportation.

Next to Best Practice is research an acceptable Max Hole Size,
else the expensive ideal is solid flat sheet metal, all 6 sides, welded seams.
Any protection betters no protection. The limit is your wallet size and passion.

Lightening vs nuclear is irrelevant, former conventional only, difference is 1 million times more for nuclear.

If you ever build one, post a pic.

Again, oxidation is your hidden, biggest enemy. :-)

[Mr. K]

you make a good point about lightning- look at how electricical is disrupted by one lightning bolt.

Imagine a million lightning bolts. Out grid wont take it.

If only someone would have had a few $trillion for ‘shovel ready projects...

oh wait.

HEY TRUMP HOW ABOUT AN AUDIT.

Good response.

Reminds me of reviewing Protection studies where breaker values are generated without considering the conductor ampacity, when the 336.4 ACSR would vaporize before the breaker or fusing would trip to protect the Xfrmr.

I spoke with a recent EE, who didn’t even now what B, D, E or H were in Maxwell’s eqns.

With a point source, striking a long transmission line, as well as other point sources, such as electronic controlled overcurrent devices, makes one wonder what secondary and tertiary effects might arise.

Evaluating HV faults is a similar study. Most obvious damage isn’t necessarily at the original cause of the fault.

[<1/1,000,000th%]

There are around 5 billion joules of energy in a lightning bolt. That’s about a millionth of a megaton of TNT. There are nuclear weapons in existence that are 20 megatons or more.

In 1962, the US detonated a 1.44 megaton bomb 250 miles above the mid-Pacific Ocean. The explosion caused electrical damage in Hawaii, about 900 miles away.
