EMP Protection for Your Car!

[Elywalton]

Here is some incredible new technology for EMP protection...  Note it is even "listed by USA Homeland Security!"

I would love for Dave to take a shot at this on Youtube!  Just sayin'

Well lets see what they have to say about that.

Hello, I have come across this advert about EMP shields.
https://www.empshield.com/product/vehicle/
Listing:
"Next Generation EMP Protection With Military Certified Testing.
"Listed by the Department of Homeland Security."

Do you have an affiliation with them and is this true or false about it being listed by yourselves?

Thanks

This is BS

To protect you vehicle from any of the listed protections you will need to take all the Electronics in your car and put them in a Faraday cage. An EMP Will destroy the computer in your car as well as stereos and any other technology residing in you vehicle.

This won't do anything for you.

In that case 2 stars is too generous given that one star is the lowest.

As with ionizing radiation, few understand what an EMP is - and this WON'T protect!

As a mechanical engineer that has worked with EMP devices, I can tell you, first-hand, that EMP is not a 'direct effect' event, like touching an electrical outlet and being shocked. It is a 'disbursed event', happening much like you see a rainstorm...but at the electron level. This is why 'actual EMP protection' is cage-encompassing. If you took a cell phone, and suspended it in a 1/4" welded wire cage (think 'rabbit cage') by rubber bands, then grounded the cage to 'earth', the EMP cascade would follow the lowest impedance path to ground...it would 'circle the cage' and 'avoid the high impedance path through the phone'. Military applications of this are often seen on aircraft, where the fuselage is aluminum. Seldom noticed, there is a 'grounding strap' (pure copper, much like a cable) that is deployed before landing. It 'drags on the ground' before the tires even touch down. This allows for the ionic charge to dissipate to ground first...and to attempt to disembark the craft without this 'grounding' can and possibly will lead to sufficient electrical shock to cause death. While this deals with 'static charge', the same forces and 'charge direction' occurs much the same way, with the same structural components...only isolation capacitance and diodes are used to prevent 'complete system charges' from building, and allows for 'electronic isolation' combined with 'frame caging' to prevent EMP from affecting 'otherwise-sensitive' components.
NONE OF THIS IS BUILT INTO A CONSUMER VEHICLE! So, when you 'wire in a capacitor' or diode to your car, even when grounded, it may assist in dissipating 'static charges', but there are no 'EMP cages' protecting your alternator, starter, ECM, etc. on that car! They are not protected. Sure, this device is tested...but as you know they did NOT test it on your specific model, they CANNOT ATTEST to the fact that it will provide ANY EMP to your car...simply that the device itself is a cage, with capacitance ability and directional grounding, to dissipate FOR ITSELF (in otherwords, it is protected...but what you mounted it to is not, unless it was ALREADY EMP CAGED!)...
Does this work? Their tests show it does...TO PROTECT ITSELF. Can it protect your 2010 Camaro, or 2012 Mustang or 2018 Silverado? Who knows? They don't...they didn't test it PER MODEL APPLICATION! (the answer is no, by the way...it won't). Caveat Emptor...buyer beware...

As a Computer Engineer I was skeptical...and correct is a fake product

Until I saw the explanation from a Mechanical Engineer (in the reviews)…this product sells false sense of security .

I saw this device and I was mind blown. Think about it...the military spends trillions of dollars in hardening their devices, infratructures, etc. If a tiny $300 device could solve the EMP risks they would not be selling to the public… and Lockheed and GDIT wouldve already bought them out haha. Im a veteran and well aware of contract requirements. MIL-SPEC is NOT a high standard is just a "good enough" for military applications. Dont be fooled by these standards theyre nothing exceeding typical engineering standards. A solar X level flare would not be stopped by a $300 device. If it sounds too good to be true then it likely is.

Special thanks to the Mechanical Engineer below for explaining the physics behind this.

What amazes me:
4.6 out of 5 stars

264 global ratings
5 star     81%
4 star     11%
3 star     3%
2 star        0%
1 star     5%

264/100=2.64 for 1%
(81*2.64)+(11*2.64)+(3*3) = 251 people fooled into this.
(5*2.64)= 13 people who are wise or wisened up to it.

Come on, this is "veteran owned business", the product has been featured on FOX, it's even 100% American made and states "patend pending".

https://healingpicks.com/does-emp-shield-really-work/

(Educated guess: there is just one 12V cap in there, plus a resistor plus a LED. Should start my own business, I guess...)

Edit:
Ooops, my bad:

Pbut they were soon being fitted as a standard feature in the car.

LOL. Just like driving around with a huge sticker on your car "Rip me off, I'm stooopid".

In a nuclear explosion my non functioning car will be the least of my problems

BTW, you could have cut the URL before the first '?' : https://www.empshield.com/product/vehicle

 like to see a teardown of the band name-Shield  plastic electrical box. how hard can it be to look inside it!
show us the electronics or is it potted? why has nobody opened one?   anonymously if you like.

To reliably protect against EMP, replace all the semiconductors with Nuvistors or other appropriate vacuum tubes.

For 12 V operation, try the 8056  https://frank.pocnet.net/sheets/049/8/8056.pdf

Glad someone started this thread.  Not a survivalist and I came across this product while chasing a rabbit.

I WENT to the report they cite and found no mention of their product.  Maybe I missed it, but that report is all about hardening important infrastructure.

Aside from that, I wonder how they tested it in real world conditions and how I get my money back if it needs to be used and fails?

Sounds like a perfect business model.

Nice 228 kA rating.
I'm sure the tiny leads in the picture will not care at all.
After all, when you are a ball of hot plasma what do you care....

Probably just three largish 30$ MOVs in a box (I'm being generous).

[Whales]

Wires:

 +12V
 -12V
 GND

This thing would have to be so tolerant of miswiring   But I guess resistors, capacitors and inductors won't care if you size them right.
