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.
This group stresses being able to stay alive for indefinite periods in life-threatening wilderness scenarios, including plane crashes, shipwrecks, and being lost in the woods. Concerns are: thirst, hunger, climate, terrain, health, stress, and fear. The rule of 3 is often emphasized as common practice for wilderness survival. The rule states that a human can survive: 3 minutes without air, 3 hours without shelter, 3 days without water, 3 weeks without food. 
While Johnny Cash advised us against falling into a ring of fire (good advice), I don’t think he would have seen this one coming. The Ring O Fire kit from Live Fire Gear combines three great products into one fire-friendly pack. The trio starts with a hot-sparking ferrocerium rod. Next comes 25 feet of FireCord. This eight strand 550 cord has an extra strand that is highly flammable. Just cut a short section free, and pull out the red strand for a volatile tinder material. You also get a Live Fire Original Emergency Fire Starter. This small tin has a fuel soaked wick inside, which burns for 30 minutes with the lid completely removed, and much longer when the lid is only partially opened. Place the Live Fire tin under your kindling to start a campfire, or use it as a candle. This sleek kit is a great fit for your camping gear, vehicle, tackle box, disaster kit or bug out bag.
Worms are edible (although certainly not desirable for most) and if you can find fresh water you might be able to rustle up some crustaceans to eat. If you’ve ever had crab or lobster, crayfish are like their mini cousins, all of which are edible. If you are near saltwater, you can try to capture shrimp, crabs, lobsters, and more in waters approximately ten meters deep. Mollusks include all of the following food sources you can sometimes find while out in the wild: sea urchins, chitons, periwinkles, barnacles, bivalves, mussels, clams, and snails.
SOG made their shovel practical survival gear by cutting back its length to a manageable 18 ¼” and its weight to an equally manageable 24 ½ ounces. It folds up to a mere 1 foot long and can be easily strapped to the exterior of any decent sized backpack. The SOG shovel also boasts a row of thick rugged teeth along the side for hacking and cutting underbrush or harvesting wood for your fire. The blade can also be rotated and used as a pick or a hoe to do more precise clearing. All in all this is a piece of survival gear you won’t want to do without.
Another concern when you’re lost in the wild is where to procure potable water. Sometimes there will be bubbling streams of crystal clear water rolling down wooded hillsides to fill your water bottle and sometimes you’ll have little more than a stagnant pool standing between you and dehydration. The LifeStraw Personal Water Filter is survival gear that can turn that stagnant pool into a lifesaver.
For Mike Mester, civil unrest is just around the corner and he aims to get everyone ready; Colorado computer programmer Preston White has collected over 11,200 types of seeds and plans for biosphere living in a Fukushima-irradiated future while friends Shane and others provide supportive help; Riley Cook spends his days working close to home and with the prepper society building underground structures.
A number of popular movies and television shows[definition needed], such as the National Geographic Channel's Doomsday Preppers, have also emerged recently[when?] to capitalize on what Los Angeles Times' entertainment contributor Mary McNamara dubbed "today's zeitgeist of fear of a world-changing event." Additionally, doomsday ideas disseminated mostly online in relation to the 2012 phenomenon surrounding misunderstandings about the Mayan calendar fueled the activities of some survivalists during the run-up to the phenomenon's purported December 2012 date of the world's demise.
Wetfire is a non-toxic product that won’t produce clouds of noxious smoke. All it takes is a tiny bit sprinkled on the camp stove to get it going even when the rain or snow is coming down in blankets. In survival situations many perish because they’re unable to create the warmth they need to counteract cold, wet conditions. Wetfire is pocket-sized survival gear that allows you to withstand nature’s worst. Wetfire has a 5 year shelf life and can be activated using any stormproof lighter or other sparking device.
If the fire is around you and you can’t escape, you don’t have many options, says Shane Hobel of the Mountain Scout Survival School. If there’s a pool or a pond nearby, jump in and try to wait it out there. Otherwise, if you have time, dig a trench that’s two to three feet deep and long enough for you to lie in. Soak a blanket in water, wrap it around yourself, and lie down in the trench. It’s risky, but at least you’ll have a chance.
