Others featured on Doomsday Preppers are more out there — literally. Robert and Debbie Earl, retired Florida chicken farmers, worry about the seas rising. So they are building a home constructed of old tires and sand-filled bottles near Alpine, Texas. Robert Earl describes himself as "Mad Max meets Rube Goldberg with a little bit of Al Gore thrown in."
Experts worry most about the grid’s nervous system: 2,000 extra-high voltage transformers. They’re 200- and 300-ton behemoths, individually engineered to meet specific power demands, and on average, they’re 40 years old. Notwithstanding the fact that 85 percent of transformers are imported, the U.S. Department of Energy says it takes between 5 and 16 months to replace a single one. According to the U.S. Federal Energy Regulatory Committee, an attack that destroyed nine of the 2,000 transformers would “cause a protracted nationwide blackout.” There’s no national cache of spare transformers. 

Radio transceiver, standard VHF marine when operating near inland shore, 121.5 MHz AM VHF guard channel capable aircraft band transceiver to contact rescuers and high overflying commercial and military aircraft visible by contrails, an optional amateur radio if a licensed radio amateur, (see Ham Radio) or an AM/FM/Weather/Shortwave radio receiver to receive precise time for celestial navigation as well as weather information
Sir Edmund Hillary and his Nepalese sherpa Tenzing Norgay made the final ascent to Mount Everest in 1953 with 30-pound survival packs. The expedition began with 400 men and 10,000 pounds of baggage, but for that last treacherous day of thin air and blizzard conditions, these men had to rely on themselves and their survival gear to reach the top and get safely back to camp.
No one thinks they’re going to be trapped by whiteout conditions or separated from their group as night falls but it happens with alarming regularity. Don’t make things worse by being unprepared. These advanced Mylar blankets cost less than 4 bucks each and weigh virtually nothing and yet can and do save lives. They’re waterproof, tear-resistant survival gear that comes in a pack of 5. As such there’s no excuse for not having them tucked away in your backpack or daypack when you set out. The very definition of essential survival gear for outdoorsmen of all stripes.
