One major upside of freeze-dried food is its convenience. Since all its water content has been removed—via a process that involves exposing food to subzero temperatures, while removing the resulting water vapor with a vacuum—it’s easier than canned goods to transport on the fly. To “cook” Wise Company’s six-grain Apple Cinnamon Cereal, you just boil three and a half cups of water, dump in the powdery contents of the bag (minus the oxygen absorber), and cover the pot for 12 to 15 minutes.
Another wave of survivalism began after the September 11, 2001 attacks and subsequent bombings in Bali, Madrid, and London. This resurgence of interest in survivalism appears to be as strong as the 1970s era focus on the topic. The fear of war, avian influenza, energy shortages, environmental disasters and global climate change, coupled with economic uncertainty, and the apparent vulnerability of humanity after the 2004 Indian Ocean earthquake and tsunami and Hurricane Katrina, has increased interest in survivalism topics.
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.
