    just finished William R. Forstchen novel, One Second After
    although a work of fiction, it is based on a very real threat to our civilization, an electromagnetic pulse explosion that could send us to a place we really don't want to be

    governments are aware of this threat but do not give it high priority

    There is a movement afoot in America to find a way to get the politicians to consider fortifying our electrical grids against EMP attack. It can be done for a lot less money than recovering from such an attack would cost, that's for sure.

    The trick is finding the rare politician willing to spend the kind of money necessary to protect the grids.

    how many such emp devices would it take to fry just the US? what would their power requirements be?

    One high altitude megaton yield nuclear device would do it...

    The downside being that that would be considered a nuclear attack on NATO, calling for
    a full retaliatory strike, and those systems are hardened against an EMP and would still work.

    Otherwise it would be much easier to directly target [blow up] the big transformers that run the
    grid. That would cut power for weeks or months, and be much easier to plan and pull off than
    deploying enough small EMP device around the country to destroy the grid/computers etc.

    The actual concern is much less about people [terrorists, or foreign powers] launching an EMP,
    instead the worry is that the Sun will fire a massive flare at us [of a size we know it can do, and
    has done, but not in recent history] that will fry our grids [and anything connected to them].

    It all depends on how much you know about the grid. Most grids have the potential for catastrophic collapse given certain specific circumstances. The secret is to know exactly where to place your EMP.

    It might, however, be a lot easier and cheaper to simply flip a switch somewhere.

    A good hacker could probably also do an awful lot of damage.

    Raise taxes!

    Destroy capitalism!

    Take away our freedoms!

    It's our only hope. 😲

    it might take only 3 high altitude nuclear detonations to disable all electronic capabilities in the US
    meaning no transportation
    no atm
    no medical supplies
    no clean water
    no sanitation
    no fire or police protection
    no food supplies or distribution
    basically back to the 17th century
    worst case scenario, 9 out of 10 people would be dead from starvation, disease, lack of medicine and medical treatment, crime, suicide, etc
    biggest threat is from some rouge nation
    korea and china and possibly iran
    launching a missile from off shore detonating 25 miles in altitude
    people would not feel anything but when their lights go out and their cars stop running, too late
    it is a real threat

    it is a real threat
    It's a really improbable threat.

    As in it's theoretically possible to do, but really unlikely to actually happen.

    The [also real] threat from a solar flare, much more probable.

    yeah
    I should stop reading doomsday scenarios
    your right
    more likely to be from a massive solar flare
    however
    the clock is ticking

    Yes it could be any time in the next few hundred millenia. Time to panic.

    Alternatively, a solar flare could be detected and the grid switched off for a day, or whatever period, then restarted when the flare has passed.

    the grids are not hardened
    so I don't know if simply shutting them down is the answer
    and detecting a solar flare, yeah 9 minutes after it's happened

    That's easier said than done, and rather inconvenient, not to mention dangerous.

    People tend to die in power cuts.

    Also, flares can be fast enough that you may not get enough warning.

    And it's more probable than that, as in it's VERY probable that we would be hit by at least one
    massive flare in the next millennia, let alone the next few hundred.
    It's reasonably probable to occur in the next century.

    Which is why steps are being taken to upgrade grids to take this kind of thing.

    Albeit less than we probably should be doing... as ever.

    I don't know of any steps being taken in the US to upgrade (much less protect) the grids.

    People want the politicians to act, but no movement yet, at least not here.
