Do you have what it takes to live off the grid?

Even before all of the hoopla over the NSA and other government organizations tracking our every digital move, there were plenty of people who had already made the decision to live “off the grid”. If you’re new to the concept, here are some things you should know.

Nico Sell, the cofounder of a secure communication app called Wickr, has appeared on television twice. Both times, she wore sunglasses to prevent viewers from getting a full picture of what she looks like.

Sell, also an organizer of the hacker conference Def Con, places herself in the top 1% of the “super paranoid.” She doesn’t have a Facebook account. She keeps the device that pays her tolls in a transmission-proof envelope when it’s not in use. And she assumes that every phone call she makes and every email she sends will be searchable by the general public at some point in the future.
