bags are great, if you have the space (avoid down sleeping bags, except for extremely cold cli-
mates, because they are worthless when wet).
6. A colloidal silver generator (see fig. 2-4 ) for making a broadband antibiotic solution that can kill
all known pathogenic bacteria (if you are without access to pharmaceuticals, this could save your
life someday, see chapter 6 for details). Can also be used to preserve drinking water so it won't
grow bacteria, and will slowly purify water by killing pathogenic bacteria, but it takes a long time
(typically several hours).

7. Flashlight with spare batteries, or a solar-recharge flashlight. I highly recommend that you pur-
chase a headlamp with LED bulbs. Headlamps (see fig. 2-5 ) leave your hands free to carry things,
or work on things. LED bulbs use a fraction of the power, are far more shock resistant, and last
far longer than traditional light bulbs, so your batteries last many times longer.
