Your next tinfoil hat will won't be made of tinfoil. A small company 
called Conductive Composites out of Utah has developed a flexible material 
— thin and tough enough for wallpaper or woven fabric — that can keep 
electronic emissions in and electromagnetic pulses out.

There are a few ways to snoop on electronic communications. You can hack 
into a network or you can sniff out radio emissions. If you want to defend 
against the latter, you can enclose your electronic device or devices 
within a structure of electrically conductive, (probably metallic) 
material. The result is something like a force field. The conductive 
material distributes the electromagnetic energy away from the target in 
every direction — think of the *splat* you get when you hurl a tomato at a 
wall. These enclosures are sometimes called Faraday cages after the 
18th-century British scientist who discovered electrolysis.

Today, Faraday cages are all over the place. In 2013, as the College of 
Cardinals convened to elect a new Pope, the Vatican's Sistine Chapel was 
converted into a Faraday cage so that news of the election couldn't leak 
out, no matter how hard the paparazzi tried, and how eager the cardinals 
were to tweet the proceedings. The military also uses Faraday cages for 
secure communications: Sensitive Compartmented Information Facilities or 
SCIFs are Faraday cages. You'll need to be in one to access the Joint 
Worldwide Intelligence Communication System, or JWICS, the Defense 
Department's top-secret internet.

Conductive Composites has created a method to layer nickel on carbon to 
form a material that's light and moldable like plastic yet can disperse 
energy like a traditional metal cage.
