Step-by-step guides for building core preparedness skills
Building a sustainable fire in adverse conditions requires site selection, moisture barriers, resin-rich wood identification, and fire lay geometry. Covers log cabin vs teepee in wind, feather sticks, and the common failures that kill a fire before it catches.
Complete bow drill fire starting guide: wood selection, moisture testing, spindle and hearth preparation, notch geometry, friction technique, and coal transfer to tinder bundle. Covers the most common failure points and effective wood pairings for North American species.
Ranking of seven fire starting methods by reliability in rain at 40°F: WetFire cubes, ferro rod, stormproof matches, Vaseline cotton balls, fatwood, disposable lighter, and standard matches. Includes failure modes and recommended loadout.
Solar Water Disinfection (SODIS) uses UV-A radiation to purify water in clear PET bottles. WHO-validated method: 6 hours in direct sun above UV Index 2, or 2 full days on overcast days. Covers bottle selection, turbidity limits, and reflective surface optimization.
Nine fire starting methods ranked by reliability in adverse conditions: ferro rod, stormproof matches, lighter, fire piston, fatwood, bow drill, flint and steel, WetFire tinder, and fire paste. Includes spark temperatures, tinder ignition thresholds, and the conditions that make each method fail.
Exact dosages, contact times, and pathogen coverage for the three main chemical water treatment options: iodine tablets, household bleach, and chlorine dioxide. Includes cold-water and turbid-water adjustments and a head-to-head comparison.
Head-to-head comparison of the Sawyer Squeeze, Big Berkey, and Lifestraw on micron rating, flow rate, weight, freeze damage risk, and virus coverage. Clear winner for each use case: bug-out bag, base camp, and long-term home storage.
Seven field-proven methods to purify water when heat is not an option: chemical treatment with iodine, chlorine, and chlorine dioxide, mechanical filtration through 0.1-micron membranes, UV sterilization, and solar SODIS. Includes pathogen specifics, altitude adjustments, and product comparisons.
