I realize that every job probably gets routine after a while, but some jobs probably get the juices flowing more than others. Here’s one that that keeps the juice flowing to all of us.
So I did a bit of research, and hey its the real deal. YOU probably encounter faraday cages/faraday shields in your every day life too. They work on the principal that if you can get an electric current to flow over the surface of a sphere, the field at each point inside the sphere created by the current on the surface tends to cancel out creating an electrically quiescent area in the middle. Some interesting applications: Mobile phones, radios and wireless networks may have no reception inside elevators or buildings built using a virtual cage of rebar or plaster with metal lath.
Ever notice the light metal grid in the door of your microwave oven? Its part of a Faraday Cage enclosure that traps the microwaves inside with your food rather than out in the room cooking you.
According to WikiPedia, some United States national security buildings are contained in Faraday cages, intended to act as a TEMPEST shield, and possibly also as a mitigation against electromagnetic pulse.
You can even buy underwear with a built in Faraday Cage, but I wouldn’t advise testing them by trying a highwire act on your local high voltage lines. (and if you do, you better get life insurance first.
