New York Nuclear PSA what to do in case of an attack

SFOGuy says...

I immediately wondered that; a low yield dirty bomb, at say, the UN on the Upper East Side would be a different EMP profile, I presume, from a higher yielded ship born bomb inside, say, a container which had cleared customs in Pakistan, and that would be different from a high altitude air burst, right? So, and the physics seems calculable if annoyingly in my past--you should be able to calculate a range of EMP from various yields?

The "Quora" answers are: a ground-based (ship based?) lower yield weapon has EMP effects of note to the 3 mile range.

An airburst would be a different issue. "Starfish Prime”. In this high altitude nuclear test, carried out in 1962, a 1.44 Mt warhead was detonated at a height of 400 km. Electrical damage, including burning out hundreds of street lamps was caused in Hawaii - about 1500 km from the point of detonation.

By contrast there was no direct blast damage at all at that range.

The maximal electric fields induced in the Starfish Prime EMP in Hawaii were estimated at 6 kV/m. At high latitudes the value could easily be ten times higher.

For electrical equipment to be damaged by an EMP from a nuclear detonation, the detonation point must be above the visual horizon.

A large yield weapon detonated 400 km above Kansas would have an EMP that extended across the entire continental US, but the ground intensity pattern of that EMP would be peaked towards the South of ground zero, it would not be symmetrical."

Sad that the article and @StukaFox both forgot the emp, that kills all electronics, making your car your tomb if it was made after 1980.
A car is only a decent shelter if it’s at the bottom of an underground parking structure that doesn’t collapse in the blast.
Cars are not escape vehicles in this scenario. There won’t be many erratic drivers, like the article claimed, because any car with a computer chip will be dead.

Very cool build. One odd thing; Stainless is beautiful; but when it fails, I understand it fails catastrophically and without warning. In some odd ways, regular steel, rusty and all, would be less scary for something which is going to hold up a heavy vehicle when you are crawling under it in an emergency (yes, jackstands but...still)...

Am I wrong for seeing Robert Downey Jr.'s visage floating in my peripheral vision during this short and waiting for the "Brough to you by Stark Industries" caption?

Anyway, just on logistics simplification alone, this is a win.

A Tesla has 18 moving parts in the drivetrain (so says quick a Google search)--and an internal combustion engine has thousands in the engine and drive (2,000?)-- That's a lot of skilled jobs in manufacturing and maintenance that aren't going to be the same as a change over happens.

I like how she talks about TRYING to think about other people's feelings and thoughts, knowing that someone is trying to shame her into guilt--and she just...can't.

The Mauser action is considered to be a very precise, very repeatable action, correct? Is that the basis for its claim to accuracy in rifles that use it?

"The guys try durian(...)"

Someone brought one of those fucking things into our office once and the evacuation of the workspace and people's stomachs was epic. You can smell that shit all the way to the ISS and it's probably the reason aliens haven't invaded us yet. It's sorta like that movie 'Signs', only instead of making no fucking sense what-so-ever, the aliens show up, smell a durian, mutter "are you fucking kidding me?!" and then get back on their spaceship and fuck off to somewhere less malodorous. This is also what keeps Tacoma mostly vacated. Seriously, the reason WaDoT lowered the speed limit to 50 on the part of I-5 that has the misfortune of passing through Tacoma is that they hate everyone west of the Cascades and this is how they get back at us. Yeah, FUCK YOU -- Tacoma may stink, but Biden's still president!

Cunts, the whole fucking lot of 'em.

That's amazing. Does every culture have a food like this? Totally "ok" as long as you grew up with it, but to anyone less acculturated--just too much?
The guys try durian in one episode lol--The Asian tree fruit--"Tastes like heaven, smells like hell"--or more accurately, rancid cat poop.

To watch someone who really understands their craft--whatever that craft is--and is this case, it's percussion---it's really enjoyable if somewhat befuddling.

Such a happy nerd day today. Was in a small meeting outside and had this marked in my calendar--after 3.5 hours of talking, suddenly stood up and said we all had to go to a wide screen; masked up and got it up and running 6 minutes before. So many happy nerdy people! So exciting!
