Steve Huffman, the thirty-three-year-old co-founder and C.E.O. of Reddit, which is valued at six hundred million dollars, was nearsighted until November, 2015, when he arranged to have laser eye surgery. He underwent the procedure not for the sake of convenience or appearance but, rather, for a reason he doesn’t usually talk much about: he hopes that it will improve his odds of surviving a disaster, whether natural or man-made. “If the world ends—and not even if the world ends, but if we have trouble—getting contacts or glasses is going to be a huge pain in the ass,” he told me recently. “Without them, I’m fucked.”

Bob Kay, a nutritional scientist in Southern California, is prepping for environmental destruction due to massive earthquakes; politician Joshua Wander is preparing for a terrorist attack, teaching others about prepping and stocking up kosher foods (matzos and mre's); Ryan Croft is prepping for a global financial crisis by cultivating alternative food sources like spirulina and earthworms.

Car electricity runs on direct current, but almost everything else is alternating current. What you need: an inverter. Some cars have them built in, but you can get one at a store for less than $40. Use the clamps to attach the inverter directly to the terminals on your car battery. Let the car run at idle and you have 110-volt AC power for as long as you have gas. With a 300-watt inverter, you'll have enough amps to run a laptop or even a television.
