The magic EMP-proof box

Even though U.S. scientists have known about electromagnetic pulses for quite some time – and, in fact, intentionally created them in the late 1950s and early 1960s during the Cold War – it’s been more recently that EMPs have entered the conversation for ordinary Americans. There is rising concern that a rogue nation or terrorist organization could seriously disrupt our power grids by detonating a nuclear weapon high above the United States or setting off an e-bomb that could do much damage on a more local level.

So isn’t it strange that a device with the capability of blocking or at least significantly reducing the effects of an EMP was invented prior to the Civil War? That’s when English scientist Michael Faraday created a cage that blocked external static and non-static electric fields. This enclosure was formed by conducting material or by a mesh of such material. Its operation depends on the fact that an external static electrical field will cause the electric charges within the cage to redistribute themselves to cancel the field’s effects in the cage’s interior.

It may not be realistic to build a Faraday cage around a country, or even a neighborhood, for that matter. But within your home it could protect your most valuable electronic equipment, including computers, during an EMP attack. Check out this explanation to learn how this device can protect electronic equipment from lightening strikes and electrostatic discharges.

Have you ever used or tried to build a Faraday cage? If so, let me know about your experience with that. Do you think that the technology that goes into the creation of a Faraday cage could ever be used to protect larger areas from EMPs? And why isn’t the government using this information? Hope to hear from you.
