Letter Re: Sizing a Retreat AC Power Generator

Jim – Great blog! I wanted to point out an important calculation everyone missed – internal combustion engines produce less power at higher elevation. Generators are (of course) rated at sea level. It’s important to de-rate generator capacity by 3.5% per 1,000 feet of elevation or your generator will be undersized. (A 5,000 “label watt” generator is [effectively] only a 4,000 watt generator where I live at 6,000 feet.) Density altitude on a warm summer day can easily be 2,000 feet higher than that. My rule of thumb: after sizing for load, size generously for elevation or you’ll be buying …


Four Letters Re: Sizing a Retreat AC Power Generator

Mr. Rawles: I saw that you recently posted my question to the blog, so I thought I’d update you. I ran the tests again and got what I believe to be a more accurate assessments. My second test showed the refrigerator consuming right at 2.7 KWH (2,700 watts) over a 24 hour period for an average of 112.5 watts-per-hour. Now mind you, that includes all the hours we were asleep and so no one was opening the door, using up ice, etc.. During hours of heavy usage it was using about 150 watts-per-hour. Test #2 for the chest freezer yielded …


Letter Re: The “Invention Nation” Documentary Television Series

Jim, I don’t know if this has been posted here or not. I have finished watching a series on the Science Channel called “Invention Nation“. The show primarily feature inventors who are inventing ways to “go green”. Many of these inventions and ideas fit in perfectly with being self-sufficient. Some of the topics are; used cooking oil for diesel engines, solar power technology, passive solar for heating homes and water, bicycle generators, etc… The series will rerun starting in March and may be worth a look for the preparedness minded. See the Invention Nation web site. Thanks to you and …


Letter Re: Sizing a Retreat AC Power Generator

Mr. Rawles: In attempting to size an emergency generator for my home, I have run across some interesting questions that I hope you and/or your other readers will be able to help me with. I lived through the blizzards of the 1990s here in the southern West Virginia coal camps, and I will never forget us and all of our neighbors being without power and unable to get out of our own driveways for 23+ days in 1993. It marked the very beginnings of my awakening to the necessity of being properly prepared. With that in mind, I am attempting …


The “Come as You Are” Collapse–Have the Right Tools and Skills

When the Second World War broke out in September, 1939, the United States had nearly two full years to ramp up military training and production before decisively confronting the Axis powers. In the late 1970s, looking at the recent experience of the 1973 Arab-Israeli War, the Pentagon’s strategic planners came to the realization that the next major war that the US military would wage would not be like the Second World War. There would not be the luxury of time to train and equip. They realized that we would have to fight with only what we had available on Day …


Letter Re: AA Cells and Mobile Power

There was a discussion about batteries a few days back on SurvivalBlog. The writer advocated using AA NiMH cells almost exclusively, with adapters for devices requiring C and D cells. While I do agree that this is a good approach for some devices, there is certainly some merit to having full size 10 Amp Hour (10,000 MAH) batteries in high [current] draw or long term use devices. Not only is capacity significantly higher on larger cells, but the maximum safe current draw is higher too. Good NiMH C cells have 2-to-3 times the capacity of AA cells, and NiMH D …


Letter Re: Keeping a Low Profile is Crucial for Preparedness

Jim, My missus and I have been into “prepping” for about 15 years. Our house has a basement and it is practically wall-to-wall and floor-to-ceiling with shelves–with just narrow aisles in between. The shelves are chockablock with storage food (all labeled and organized “FIFO“-style), medical supplies, assorted “field” type gear, tools, barter/charity stuff, ammo cans, propane cylinders (that fit our camp stove and camping lantern), reels of field phone wire, paper products, and so forth. Following the example of Mr. Whiskey (from your “Profiles“) we have recently built up 27 sets of designated “charity duffles”, each packed in a cheap …


From the SurvivalBlog Archives: Start With a “List of Lists”

Start your retreat stocking effort by first composing a List of Lists, then draft prioritized lists for each subject, on separate sheets of paper. (Or in a spreadsheet if you are a techno-nerd like me. Just be sure to print out a hard copy for use when the power grid goes down!) It is important to tailor your lists to suit your particular geography, climate, and population density as well as your peculiar needs and likes/dislikes. Someone setting up a retreat in a coastal area is likely to have a far different list than someone living in the Rockies. As …


AA Cells and Mobile Power, by Brandon in Utah

The size AA battery is the ubiquitous form of mobile power that is presently available. There is a large amount of off the shelf devices that use AA cells. They are available everywhere at low cost. They are cost effective and very safe for lighting. The breadth and depth of equipment available in a portable format is unparalleled by any other type of battery. I will cover the known factors on how to care for and use this resource to help end users get the most out of their equipment. To start, some general information that covers all types of …


Prepare or Die, by J. Britely

Throughout my life I have been caught unprepared several times and while nothing seriously bad happened, it easily could have.  I have been lost hiking.  My car has broken down in very bad neighborhoods – twice.  I have been close enough to riots that I feared they would spread to my neighborhood, been in earthquakes, been too close to wildfires, been stuck in a blizzard, and have been without power and water for several days after a hurricane.   I managed to get myself out of each situation, I thanked God, and tried to learn from my mistakes.  I could have …


Two Letters Re: Grain Storage and Preparation

Sir; We have what may be stupid question, however, we do not know how to grind wheat. We would like to ask how to prepare wheat for cooking and use.We have searched your great site but I did not find the answer on this. We would like to take advantage of this inexpensive food. Thanks so much . Your work is appreciated. – EG   Mr Rawles, My family and I are doing our best to prepare for the tough times ahead. Something’s brewing, I’m sure we all can feel it. One thing we’d love to keep a store of …


Sources for Free Survival and Preparedness Information on the Internet, by K.L. in Alaska

Recent comments in SurvivalBlog provided excellent advice on using the public library. You can gain lots of knowledge with no expense, then purchase only those books you want to keep on hand for personal reference. Also, many colleges and universities loan to local residents, so you can use them too, even if you aren’t a student. If your local libraries participate, a great resource is Worldcat. It lets you search for books from home, then go check them out, or get them through interlibrary loan. What will happen to the Internet when the SHTF? There’s no guarantee it will survive. …


Letter Re: Hunkering Down in an Urban Apartment in a Worst Case Societal Collapse

Hello, In the event of a disaster (I live in New York City) I intend to shelter in place until all the riotous mobs destroy each other or are starved out. I am preparing for up to six months. I have one liter of water stored for each day (180 liters) and about 50 pounds of rice to eat as well as various canned goods. I have not seen on your site anything about heat sources for urban dwellers who intend to shelter in place. I’m assuming that electricity would go first soon followed by [natural] gas and running water. …


Letter Re: Coleman Fuel–Uses and Storage Life

Hi Jim, According to Coleman’s web site, Coleman fuel can be stored for 5 to 7 years. I wondered if a chainsaw with the correct oil additive run on Coleman fuel. So I did a web search, and this is what I found, over at the Timebomb 2000 (Y2K) Discussion Forums, posted back in 1998] – E.L.: Coleman Fuel the Final Word! Boy What did I start? I have seen more rumors and half truths about Coleman fuel since I posted that it did work on engines!! Coleman fuel is a very highly refined version of gasoline! It has no …


Letter Re: Sources for Gasoline and Diesel Fuel in a Grid-Down Collapse

Dear Jim: There have been a lot of posts recently about bug-out vehicles and such on SurvivalBlog. Of course, every car or truck requires fuel, and in a sudden grid-down situation there will be a bunch of fuel in underground tanks at most every gas station, unable to be pumped out due to the lack of electricity. I have observed oil company trucks filling these tanks, and it appears they simply pry up some covers and drop the fuel into the tanks. How deep are these tanks, and can the fuel be pumped out by some kind of lightweight hand-cranked …
