Batteries Power Storage Units (PSU)
NOTE: When dismantling any battery, there is a level of toxicity and exposure to acid. NEVER open up a battery and remove the electrolyte. There are many types of flooded batteries that use toxic metals. SurvivorDuty will only demonstrate the less harmful simple flooded lead acid and nickel iron batteries. This website is dedicated to inform the reader concerning reconditioning in a time of crises but the reader should NEVER attempt what is demonstrated here for batteries are cheap and available to replace as new then to dismantle an aged battery that will offer no benefit to the user.

If you read our post “HOW TO BUY A REAL BUCKING CROSSCUT SAW,” a simple flat carbon steel saws may be inexpensive, easy to fabricate, cheaply produced, but I would not recommend using them for logging or bucking all the time, but I would recommend hanging them on a wall for a showcase. I have acquired an authentic, 2 person lanced tooth pattern, straight back bucking saw from my area, a historical logging county, around the 1940’s. The bucking saw I have is flat carbon steel saw, a poor man’s saw at that time. This saw is rusted, the set is off, and worn. Inexpensive saws of the 1940’s and same as today, they do cut wood, for short duty life, yet they are NOT Survivor Duty quality for they are supply chain dependent. See Figure (1).

Asteroid called 2016 QA2 back in August 2016 and asteroid AG13 this January 2017 miss our planet only by a few hundred miles. These objects were both in the same class, over 100 feet in diameter, but so small in the vastness of space that there’s almost nothing we can do to detect them. Even a rock over 100 feet in diameter can still cause a lot of damage even to the point of sustained infrastructure disruption depending on the impact zone. The blast of such meteors burning through our atmosphere would be about 30 times as powerful as the atomic bomb dropped at Hiroshima. The impact to the surface of the earth would depend on the decent angle of the object. Most asteroids have shallow angles of attack and would simply skip across the earth’s atmosphere then back out to space, but not all of them, and we are not always that lucky.
