I can’t agree with your solution for water purification. If the argument is to “also” include scenarios where boiling isn’t practical, there are other options that fit the bill. For us, we’ve been using a Berkey filter system in our home instead of something that needs water pressure or power to serve in both bug out and Flint, MI like scenarios. We use it day to day today. Not cheap upfront but the cost per litre/gallon over time is a fraction of what you’ve proposed – with all due respect.
I very much agree the article was amazingly detailed but i am neutral about the permits…on one hand you can get them and the county will have on paper where your bunker is which by the way the general public can look at or take the risk of no permits and guarantee that no one other then yourself and whoever you choose knows the location of you bunker….personally i would take the risk….
What Jennifer, a self-described prepper who declined to share her last name for security reasons, didn’t anticipate was the sheer force of Maria’s rains and 155 mile per hour winds — and how little the storm shutters would do to protect her home. “I was taking water out of the bedrooms, the living rooms, the hallways,” she says. “The house was flooded.” At one point, a piece of debris flew off a neighbor’s roof and got stuck between the outside wall of Jennifer’s pantry and the storm shutters, ripping off a pair of windows in the process.
In other words, the doomsday “preppers” you may have previously viewed as paranoid might just be onto something. With the idea that it may be high time to prepare for the worst, we’ve rounded up a selection of end-of-days bunkers on the market, potentially enabling you to survive annihilation and help carry on the torch for humanity. There are properties available at every price point, ranging from $25,000 up into the millions, and they run the gamut from basic survivalist co-op apartments to vast underground former military compounds left over from the Cold War.

It isn't hysteria, and GMO isn't 'evolution'. One of the biggest issues for preppers and survival is that GMO seeds will not reproduce in the same way if the seeds are saved and re-used. In fact, in many instances (maybe all?), it's illegal to save the seeds and re-use them! It's far better to track down heirloom seeds that are native to your area and/or compatible with your climate.
