Protecting your Tesla from nuke EMP

[MMoe]

I looked into the EMP Shield device a bit more. I think now that it probably is a scam. Would need better evidence then what is currently on their site to show that it can actually shield a car or house. Mailing address appears to be a closed bowling alley in Kansas... unless Google street view hasn't updated in the last few years!

That's all just fluff. They don't actually say it does anything. It can't do anything, with those 3 micro wires, and no grounding, it's not shielding anything.

Not an EE, but I have set up a faraday cage for testing radios in a shielded environment. Needed a fairly stout ground strap to the 10 ft ground rod, just like your house. And that was just to shield stray emfs, not a nuke blast.

That website just screams scam. Run away.

Yes. Stay away. Thanks for checking. I often forget how many people are happy to lie for money.

I looks like for the month of February they are running a deal — free volcano insurance if your purchase 3 or more devices!

Maybe... but why not look at the research on their website... empshield.com before completely dismissing it.

Yes but ... If it all turns out to be so much tosh, how are you going to get your money back?

It's an ideal business because you can claim whatever you want

Any suggestions on how to protect our Tesla from EMP if there is a nuke attack?

Where are you going to drive it?

How are you going to charge it?

How are you going to stop people from taking it off you?


Personally, I'd just want to be sitting on the big red X ... right in the middle of Ground Zero. I'm not one for the survivalist (ie medieval) lifestyle

We like to think of the Faraday cage as a fish net of wire to catch electrons which would otherwise damage your electronics.

What is the effect if we ground the Tesla to that ten foot ground rod with a heavy mesh? What about windows? There has to be a quick method which one could use if you had time.

correction .... but why not...

I'm just considering getting one.. so I don't claim to be an expert.. but here is a little bit of testing details from their website... (be interested in people's informed thoughts on this device)...

EMP Shield is a family of incredibly robust EMP, solar flare, and lightning defense technologies. ​

They have been designed to exceed the US Military requirements for protection against a high-altitude nuclear detonation that results in an electromagnetic pulse. This family of products has been tested at Keystone Compliance, a DOD Certified Testing Laboratory, to verify compliance with the following Military Standards:

MIL-STD-461-RS105 Transient electromagnetic pulse of up to 50 kV/m, double exponential wave with a rise time in the nanosecond range, that is applied to the equipment under test (EUT) at least 5 times. We tested at 50 kV/m and also 90 kV/m (80% above required testing voltage).

MIL-STD-188-125-1 High Altitude EMP

MIL-STD-461G Control of Electromagnetic Interference

MIL-STD-461-CS-115 The purpose of CS115 is to test an electronic or electrical system to withstand signals coupled onto the test unit’s associated cabling. The test unit will be subjected to rise and fall times, pulse width, and amplitude as specified on Figure CS115-1 at a 30 Hz rate for one minute;

MIL-STD-461-CS116 applies to 10 kHz to 100 MHz for all interconnecting cables, including power cables, and individual high side power leads;

MIL-STD-461 CS117 apples to all safety-critical equipment interconnecting cables and non-safety critical equipment with interconnecting cables/electrical interfaces that are part of or connected to equipment performing safety critical functions. The goal is to test the unit’s ability to withstand lightning transients coupled onto the test unit’s associated cables and power leads;

MIL-STD-464C Electromagnetic Environmental Effects Requirements for Systems.


Our test results show that we begin shunting the over-voltage condition in less than 1 nanosecond, and our units are designed to shunt over 100,000 Amps per phase. Our devices are scalable to any size.


Summary of capabilities:

Features:

1. Quick acting HEMP surge protection that switches in less than 500 trillionths of a second.
2. High current shunting capability above 100kAmps.
3. Exceeds MIL-STD-188-125-1, MIL-STD-464C, and MIL-STD-461G requirements.
4. Units are designed to protect power, control, data, communications, and radio antenna input.

This is written with just enough engineering jargon and random MIL-spec standards tossed in there to make someone with no engineering knowledge think it is legitimate - classic scam site style.

classic scam site style.

Does it have poor grammar as well?

I can see a run on aluminum foil coming...

With the current risks, now is the time to prepare.

Yes...Medication helps.

Ok, so I had an interesting experience today that ties in to this thread’s topic. I was interested to see what people think about it. We have a back-up generator that we are going to replace. The company that is maintaining it and will likely replace it visited today, and the owner was very interested in my tesla. We were chatting, don’t remember how this came up but he said he had a device in his truck called, EMP Shield, that created a field that would protect his truck from an EMP blast. He wasn’t worried about nuclear warhead driven EMP affects but rather a missile just designed to create an EMP blast. He has these devices on all his vehicles and on the in take and main feeds for his electricity in his house and on his backup generator. Does this make engineering sense, i.e., would this work?

Not saying I’d put it in my car, was just curious.

Sounds like those expensive RF-destroying (scam) devices they sell on Amazon, that plug into your 120v outlet. When torn down, there's nothing except (maybe) a resistor connected to the plug.

I think someone bought a LOT of expensive Kool-Aid.

Darn. I wish I had read this before I invested my life savings in their IPO.

HODL and you’ll be fine.

RF destroying? I thought it saved electricity. One trick power companies…

Now it does both? I’m in! /s
