    LOL Somebody thinks it can be done. EMP-proof data center.

    Betting against an EMP event is a gamble.

    EMP protection can be built into a data center at very little additional cost, said Kris Domich, president of Cyber Innovation Labs - Professional Services (CIL). The company is the founding member of EMP Grid Services, a recently formed company responsible for the EMP-ready data center in Boyers, Pa. CIL provides infrastructure services.

    during the 50s, 'harden facilities' were built that had 4 foot thick reinforced concrete outer walls to protect 'sensitive and secret military equipment'. guess the facilities worked as it scared the bad guys enough so they didn't launch missiles to test the harden facilities.

    to the best of my limited knowledge, the ability to generate a piece of transportable equipment capable of generating an emp pulse of sufficient power to take out sections of cities doesn't exist.

    not sure what they are bragging about as most computer centers since the 60's have been build in Faraday cages, put completely on ac/dc/ac power distribution and use appropriate sized filters so to protect ground system, both electrical and signal ground systems.

    most forget the signal ground and let it float while some tie the two together thinking they are the same potential.

    ipse

    i chuckled at their example that the last major sunspot activity (1859) took out the advanced electronics at the time - telegraph. duh the bare wires running across the land are super conducting and were not isolated or grounded when they entered the facilities ..

    I don't see any reason to consider EMP-resistance particularly impossible.

    There are plans and parts lists on the internet (go find them yourself and give NSA something to do) for constructing EMP-proof cages sufficient to withstand an airburst detonation EMP within less than one mile (laterally) from the site of the cage. Everything from a galvanized trash can to room-sized. And from room-sized you can scale up to building-sized.

    So, what's the heartburn driving you commentary? Is it thast the IT industry pushes EMP protection to the bottom of the list of worries?

    stay safe.

    if your commentary was directed at me, i was only pointing out the fact that nightmare's wonder article is olde news per se.

    myself i have my sustainable electronics stored, when not in use, in olde microwave shells, w/electric cords cut off, and their cases are multiple point grounded with # 4 braided wire to 20foot ground rod(s).

    never know when the solar flares are going to blossom or teh neutron beams are going to be used.

    I've got all my sensitive computer data backed up on Hollerith cards.

    Have been thinking about buying a 1960/70s era car that is non-electronic as well - either GMC pickup or chevy camaro.

    +1 Just so.

    They're not much good, though, as in this case, if they're not read and understood.

    Ha! I attended the last university to stop using those hair-pulling machines.

    Most data centers are already EMP-hardened to a significant extent for one simple reason: lightening.

    Electromagnetic pulses destroy electronics because the rapid change in the EM field induces current in all conducting materials. Lightening destroys electronics by imparting current in conducting materials. Data centers are already hardened against electrical surges from outside the data center. The problem is their walls, ceilings, and floors provide little shielding from an EM pulse. Thus, even though they are edge-hardened, and can block external surges created by the pulse, the pulse itself walks right through the facility, creating surges throughout the infrastructure of wiring.

    As someone mentioned, a faraday cage is part of the solution. Wiring, however, needs additional protection. Fiber is immune, as it's non-conducting. Shielded coaxial and twisted pair are, well, shielded. Provided he shielding is grounded, you have a tiny Faraday cage surrounding the wires along their length. Un-shielded twisted pair, commonly known as Cat-5, is largely immune due to the way twisted pair tosses off EM interference.

    So, ensure the data center's edge is well-protected against surges and protect the innards with a well-grounded Faraday cage, and things will likely survive even strong EM pulses.

    By the way, if you want to protect a laptop, just stick it in an old microwave. Be sure it's plugged in, though, as the cage needs to be grounded: "...certain computer forensic test procedures of electronic systems that require an environment free of electromagnetic interference can be carried out within a screen room. These rooms are spaces that are completely enclosed by one or more layers of a fine metal mesh or perforated sheet metal. The metal layers are grounded to dissipate any electric currents generated from external or internal electromagnetic fields, and thus they block a large amount of the electromagnetic interference."

    Similarly, "A microwave oven utilises a Faraday cage, which can be partly seen covering the transparent window, to contain the microwave energy within the oven."

    Faraday cages can have more than one layer. If you really want to protect that laptop, wrap it in newspaper (an insulator) then copper foil before putting it into that old microwave.

    No Faraday cage will stop neutrons as they're not electrically active.

    Hydrocarbons and water are effective forms of shielding, primarily because they're either readily available or comparatively cheap. The effectiveness of shielding is noted by it's "halving thickness," the thickness required to cut the radiation in half. The problem with neutrons is that shielding which stops neutrons often generates gamma rays when the neutrons hit it, thereby requiring additional shielding. Concrete, gravel, and dirt provide good shielding against neutrons and the gamma rays produced as the neutrons hit the shielding itself. However, you still need a lot of it, like three feet. Steel is quite good at stopping gamma rays, but you'll need 1 inch of it to cut the gamma rays in half. Lead is twice as effective, with a halving thickness of 0.4 inches. Other gamma-ray halving thicknesses are as follows: Steel: 0.99"; concrete: 2.4"; packed soil: 3.6"; water 7.2"; lumber: 11"; air: 6,000".

    So, a good neutron shield would be a concrete bunker with 12" walls located at the bottom of a lake...

    A .1 or a .5 K would do limited damage, but eat up the electrons,eh?

    I understand that when the CCCP collapsed about 275 of their version got misplaced. Probably an NFA item with a $200 tax stamp for private ownership tho. .......Sorry, dreaming again.

    A backpack nuke wouldn't generate an EMP because it's not in the right position. Nuclear blasts release high-energy photons (gamma rays) which knock electrons off atoms with low atomic numbers, primarily oxygen and nitrogen. That flood of electrons doesn't do much in a ground burst, or even a low altitude air burst. Crank up the altitude to between 30 and 300 miles, however, and those electrons interact with the ionosphere. These electrons are then trapped in the Earth’s magnetic field, giving rise to an oscillating electric current. This current is asymmetric in general and gives rise to a rapidly rising radiated electromagnetic field called an electromagnetic pulse (EMP). Because the electrons are trapped essentially simultaneously, a very large electromagnetic source radiates coherently.

    Put another way, it's works similar to a laser, but instead of producing light, using a nuke to pump electrons into the Earth's magnetic field generates "lased" electromagnetic pulses. Source.

    That's most likely to come from North Korea. Whether it actually detonates before our own defenses blow it out of the sky is anyone's guess.

    What concerns me far more are non-nuclear EMP generators, where explosives are used to move superconducting coils through dense magnetic fluxes in order to generate an EMP. These would have far less energy than a HEMP, but could easily take out a few city blocks.
