The Very Real Threat of EMPs

October 27, 2010 -

Only in video games and sci-fi movies would we expect our worlds (communications, electronics - basically all the modern trappings of our society) to come to a crashing halt due to either a natural or weapons-based Electromagnetic pulse caused by a major solar storm or an A-bomb. Sure, it all sounds like the backdrop from a Call of Duty or Medal of Honor game (or one of those crazy History Channel specials on 2012), but some politicians are taking the threat seriously. USA Today has a fascinating article on the subject. We cover the parts we like.

An Electromagnetic pulse (EMP) is a massive burst of atmospheric electricity. Whether powered by geomagnetic storms, nuclear blasts, or a new generation of weapons supposedly developed by military types around the world, the result equals burned out power lines and electrical equipment - a society without power.

Politicians believe the threat is very real; former House speaker Newt Gingrich told a Heritage Foundation audience last year that we are not ready for such an occurrence:

"We are not today hardened against this," he said. "It is an enormous catastrophic threat."

Meanwhile, a bill called the "Grid Act" (PDF) passed in the House of Representatives awaits approval in the Senate. The bill "amend(s) the Federal Power Act to protect the bulk-power system and electric infrastructure critical to the defense of the United States from cybersecurity and other threats and vulnerabilities."

"The electric grid's vulnerability to cyber and to other attacks is one of the single greatest threats to our national security," Rep. Ed Markey, D-Mass., said in June when he introduced the bill to the House of Representatives.

So what are the solutions? Here is an important excerpt on that:

Although the physics underlying the geomagnetic and nuclear pulses are fundamentally the same, they have different solutions. A geomagnetic storm essentially produces a long-building surge dangerous to power lines and large transformers. A nuclear blast produces three waves of pulses.

Limiting the risk from the geomagnetic-storm-type threat involves stockpiling large transformers and installing dampers, essentially lightning rods, to dump surges into the ground from the grid. Even if such steps cost billions, the numbers come out looking reasonable compared with the $119 billion that a 2005 Electric Power Research Institute report estimated was the total nationwide cost of normal blackouts every year.

Remember when we only had to worry about nuclear war and pandemics? Yeah, those were good times. Want to learn about some games and movies that use EMP as a core element? Check out this Wikipedia entry.

Re: The Very Real Threat of EMPs

Scientific fallacies aside, the best way to protect our technology from EMP is to de-centralize our power production. Setting up small, numerous local power sources rather than big central plants would help mitigate the risk of EMP devastation.

Re: The Very Real Threat of EMPs

Realisticly, no EMP, even from the Sun, would knock out power to the entire contenient, which is what would need to happen to shut off power to the entire United States since Canada shares the same power with us. 

What always bothered me about that particular scene in MW2 is that the power outage cascades from southern New York down to Jacksonville, FL.  Other than completely ignoring the Northeast power grid that we all learned about when New York went dark several years ago, the cascade effect would not grow that large.  Our very infastructure is set up to shut down if any surge is detected coming down the line to prevent any damage to the power plant/station. 

Not to mention that most of the newest trunk lines are shieled to protect from anything but a direct blast, so phone service would be available in a lot of places near the blast.

Oh yeah, and a shockwave from a nuke would not spread over 1000 miles to destory the ISS.  Sorry, either it is low enough in the atmosphere to cause the EMP effect and spread over quite a ways, or it was high enough for the explosion not to react to anything.  I guess the Infinity Ward people just watched Independence Day and assumed that is how a nuke worked in outer space.

Or, you could just hide a tesla coil in the computer lab closet like some joker did for a senior prank.

 

Re: The Very Real Threat of EMPs

"EMP Electromagnetic pulse" -- wow.  I frequently hear single-word tautologies like "ATM machine" and "PIN number", and occasionally even a two-word one like "for your FYI", but I do believe this is the first time I've ever seen a triple-redundancy.

Re: The Very Real Threat of EMPs

While it could have used a couple of commas, the intent was to define the acronym. I think that was clear for most intelligent people.

Re: The Very Real Threat of EMPs

And why is that significant?  Do Tautologies cause EMPs?

MaskedPixelanteNumber 3: Night Dive was brought to the attention of the public by a massive game recovery, and yet most of their released catalogue consists of games that other people did the hard work of getting re-released.04/17/2014 - 8:46pm
MaskedPixelanteNumber 2: If Humongous Entertainment wanted their stuff on Steam, why didn't they talk to their parent company, which does have a number of games published on Steam?04/17/2014 - 8:45pm
MaskedPixelanteNumber 1: When Night Dive spent the better part of a year teasing the return of true classics, having their big content dump be edutainment is kind of a kick in the stomach.04/17/2014 - 8:44pm
Matthew Wilsonhttp://www.giantbomb.com/articles/jeff-gerstmann-heads-to-new-york-takes-questions/1100-4900/ He talks about the future games press and the games industry. It is worth your time even though it is a bit long, and stay for the QA. There are some good QA04/17/2014 - 5:28pm
IanCErm so they shouldn't sell edutainment at all? Why?04/17/2014 - 4:42pm
MaskedPixelanteNot that linkable, go onto Steam and there's stuff like Pajama Sam on the front-page, courtesy of Night Dive.04/17/2014 - 4:13pm
Andrew EisenOkay, again, please, please, PLEASE get in a habit of linking to whatever you're talking about.04/17/2014 - 4:05pm
MaskedPixelanteAnother round of Night Dive teasing and promising turns out to be stupid edutainment games. Thanks for wasting all our time, guys. See you never.04/17/2014 - 3:44pm
Matthew WilsonAgain the consequences were not only foreseeable, but very likely. anyone who understood supply demand curvs knew that was going to happen. SF has been a econ/trade hub for the last hundred years.04/17/2014 - 2:45pm
Andrew EisenMixedPixelante - Would you like to expand on that?04/17/2014 - 2:43pm
MaskedPixelanteWell, I am officially done with Night Dive Studios. Unless they can bring something worthwhile back, I'm never buying another game from them.04/17/2014 - 2:29pm

NeenekoAh yes, because by building something nice they were just asking for people to come push them out. Consequences are protested all the time when other people are implementing them.04/17/2014 - 2:06pm
Matthew Wilsonok than they should not protest when the consequences of that choice occur.04/17/2014 - 1:06pm
NeenekoIf people want tall buildings, plenty of other cities with them. Part of freedom and markets is communities deciding what they do and do not want built in their collective space.04/17/2014 - 12:55pm
Sora-ChanI realize that they have ways getting around it, but one reason might be due to earthquakes.04/17/2014 - 4:42am
Matthew WilsonSF is a tech/ economic/ trade center it should be mostly tail building. this whole problem is because of the lack of tail buildings. How would having tail apartment buildings destroy SF? having tail buildings has not runed other cities around the US/world04/16/2014 - 10:51pm
Matthew WilsonAgain the issue is you can not build upwards anywhere in SF at the moment, and no you would not. You would bring prices to where they should have been before the market distortion. those prices are not economic or socially healthy.04/16/2014 - 10:46pm
ZippyDSMleeYou still wind up pushing people out of the non high rise aeras but tis least damage you can do all things considered.04/16/2014 - 10:26pm
ZippyDSMleeANd by mindlessly building upward you make it like every place else hurting property prices,ect,ect. You'll have to slowly segment the region into aeras where you will never build upward then alow some aeras to build upward.04/16/2014 - 10:25pm
