    Cspan coverage of the Heritage Foundation discussion on EMP. An hour and a half. I haven't been through all of it yet, but plan to. Just to hear about what the current state of preparedness (or lack of) is good. With all the money going to entitlements I don't see anything being done to protect the grid.

    Maybe there might be benefits to a carbureted bike after all. If you have an older diesel you're golden.

    EMP from a nuke doesn't seem like a valid threat, but you guys know you can make an EMP that will destroy everything electrical for a mile pretty easily, right? Though it's illegal in like 48 of the states.

    Why would you say it isn't very likely from a nuke? I can think of a lot of actors who have stated they would like to destroy the US. The technology is there and enemy states could gain considerably by supplying a second party with the means.

    Word on the net is it would take a pretty high-yield nuke (50-100+ megatons) detonated at the edge of space - ~60 miles up - to generate an EMP that would really screw up most of the country. Very few nations possess the ability to pull that off at the moment.

    Granted, Iran is working toward improving their Shahab missiles and they may be able to achieve that now or very soon. As of right now, they don't seem to have high-yield nukes. If they did, would they mess with us or hit Israel?

    Thanks for the link, OP. While it seems unlikely at the moment that this is a serious threat, the threat is not 0; there is at least some potential of this happening.

    We have railguns, a lot of early warning systems, the North American Missile Defense network, planes that can go along the top of the atmosphere, and places like Hoover Dam and Niagara Falls that definitely wouldn't be effected by the EMP. It would take about 4 feet of concrete to completely stop an EMP. In major cities, thats not that much. I know that MISO and MAP are completely protected against a nuclear EMP. Anything designed to take down a large area would only do so for a week or two. Most vital infrastructure is well protected against EMPs. You'd have to get something inside to take them down, which wouldn't be too hard, but the bigger EMPs would block against smaller EMPs, and if the smaller EMPs went off first, the entire nation would be at the highest alert in about 30 seconds.

    I heard a simple steel trash can will prevent any EMP from destroying any electronics inside it. So if you keep your radios, range finder, night vision etc. in there it will be fine.

    Anyone know if that's true?

    Quebec Hydro was knocked out a few years ago by a CME and took down a good portion of the east coast.

    It may be that a big portion of the grid is protected from an EMP, but the devices that use it probably aren't. Think about all the data centers, routing equipment, communications equipment (eg: cell towers) that would fry...it would take somewhat longer than a week or two to come back from that. Cars, watches, radios, computers and even mundane things like kitchen appliances are potentially at risk. Granted, it isn't a very high risk but they're susceptible.

    If it's a concern to anyone, keep some electronics (radio, CB, GPS, watch, whatever) in a grounded metal box. It'll work reasonably well as a Faraday cage.

    Mhmm, but even the lower floors of an apartment building, anything under a parking garage, places with a mountain in the line of sight between the event and themselves, will all be fine. Even just all the buildings will add up when weakening the pulse. And, I'm not 100% sure, but I think the internet would still be functional.

    Got a spare fleshlight buried in a copper-plated tackle box in the backyard, JIC.

    :eek:.......

    Anyway, according to the government in a worst case scenario around 25% of small electronics (phones, laptops, microwaves etc) would be wiped out, around 40% of major parts of the grid would be damaged. It would take, in a worst case scenario, around 6 months to get everything back up and running. It would not be the end of all technology as we know it like scifi movies say it would be. It definately would not be awesome, but it wouldn't be the end either. People would still have acess to the things they needed they just might have to go somewhere to get them instead of to their laptop, or their microwave. People might have to get out more and pick stuff up as they need it instead of relying on their big freezer to store everything for a couple weeks at a time.


    The biggest and worst part of an emp would definately be vehicles. Imagine if 50% (IIRC that was the percentage) of all vehicles went down. Aircraft, cars, motorcycles, boats, 18 wheelers, trains, ships, atvs, It would be a nightmare. food would be more scarce because shipping would be interupted.

    Most of the disaster from an emp would be inflicted not by the emp, but by panic. I have no doubt that even though civilizations was still there, just in a crippled state, that people would go absolutely bat**** crazy. Which would result in much more chaos than the emp could ever dream of.


    Many/most military and government equipment is hardened (resistant to emp) so the government wouldn't be very affected. Most big hubs for communications such as server bases and central points for the internet are hardened, so the information world would still be in good shape, though your computer may not work.


    In the event of an emp, I would expect a week or so of civility followed by a few weeks of lawlessness and then the government would step in and pretty much martial law it up until everything was back and running properly.... I would say, in the case of an emp, prepare for a few months of rough times.
