This book will help you to prepare for two end-of-the-world-as-we-know-it (TEOTWAWKI) events: the EMP attack and the solar storm. Practical preparations are outlined, including steps to meet the fourteen basic needs in the absence of modern utilities, and the use of Faraday cages and uninterruptible power supplies to protect personal electronics. Several techniques for constructing ad-hoc Faraday cages are presented. The shielding effectiveness of homemade Faraday cages is measured and compared, including metal garbage cans, foil-wrapped boxes, fire safes, static bags, ammo cans, and microwave ovens. Finally, a low-cost method of constructing a room-sized Faraday cage is presented.
