When bands of marauders start roaming the streets, how are you going to keep them out? Tear down a few walls, says Timothy Ferraro, a twenty-five-year construction veteran who's thought about this situation plenty while watching The Walking Dead. "Assuming the attackers don't have a battering ram, you should be able to keep them out using the lumber and drywall already in your home," he says.
The survivalist hard-on (yep, and I'll do it again, too) for prophylactics untouched by chemical pleasure-enhancers is the result of drilling deep (told you) into the magical properties of our latex friends. According to our research, these flexible, durable, waterproof wonders will be as much of a deciding factor in your dystopian longevity as fire and can openers.
An American hedge-fund manager in his forties—tall, tanned, athletic—recently bought two houses in New Zealand and acquired local residency. He agreed to tell me about his thinking, if I would not publish his name. Brought up on the East Coast, he said, over coffee, that he expects America to face at least a decade of political turmoil, including racial tension, polarization, and a rapidly aging population. “The country has turned into the New York area, the California area, and then everyone else is wildly different in the middle,” he said. He worries that the economy will suffer if Washington scrambles to fund Social Security and Medicare for people who need it. “Do you default on that obligation? Or do you print more money to give to them? What does that do to the value of the dollar? It’s not a next-year problem, but it’s not fifty years away, either.”
For global catastrophic risks the costs of food storage become impractical for most of the population  and for some such catastrophes conventional agriculture would not function due to the loss of a large fraction of sunlight (e.g. during nuclear winter or a supervolcano). In such situations, alternative food is necessary, which is converting natural gas and wood fiber to human edible food.
When I got into bed that night, I noticed I was feeling a little off. Though I’d technically consumed enough calories, my stomach was still gnawing with hunger, and when I woke up the next morning, I felt energyless. I phoned Dr. Lisa Young, a New York–based nutritionist and adjunct professor at NYU, with a question: Is it really possible to live off freeze-dried food?
Over the years, Huffman has become increasingly concerned about basic American political stability and the risk of large-scale unrest. He said, “Some sort of institutional collapse, then you just lose shipping—that sort of stuff.” (Prepper blogs call such a scenario W.R.O.L., “without rule of law.”) Huffman has come to believe that contemporary life rests on a fragile consensus. “I think, to some degree, we all collectively take it on faith that our country works, that our currency is valuable, the peaceful transfer of power—that all of these things that we hold dear work because we believe they work. While I do believe they’re quite resilient, and we’ve been through a lot, certainly we’re going to go through a lot more.”
Fear of disaster is healthy if it spurs action to prevent it. But élite survivalism is not a step toward prevention; it is an act of withdrawal. Philanthropy in America is still three times as large, as a share of G.D.P., as philanthropy in the next closest country, the United Kingdom. But it is now accompanied by a gesture of surrender, a quiet disinvestment by some of America’s most successful and powerful people. Faced with evidence of frailty in the American project, in the institutions and norms from which they have benefitted, some are permitting themselves to imagine failure. It is a gilded despair.
Bombs rain from the skies, alien ships descend with lasers ablaze, improbably proportioned, irradiated sea monsters tear through essential infrastructure. You'd think that running, screaming, and finding clean underwear would top the list of activities likely to improve your chances of living, followed closely by finding a sustainable food source and offering sexual favors to the person with the most impressive arsenal. Unless you were a prepper, in which case you'd be worrying more about the safety of your cigarette stockpile.
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.
