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?
Don’t buy in bulk unless you plan to repackage your food into Mylar bags, vacuum-sealed bags, or canning jars. Once you open a large container of food—such as flour or coffee—the flavor and texture start to degrade. Storage containers provide an airtight seal that keeps rodents and pests out. Proper storage also keeps food nutritionally stable and extends the shelf life.
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.
