Letter Re: The Fragility of the US Power Grid

Hello: I enjoy your web site every day and am very close to the 10 Cent Challenge, I promise. I work for a medium sized electric utility in the west and I can tell you first hand how weak and ratty the executives have allowed the system to become. The name of the utility game has now become ‘defer maintenance to artificially inflate the price of your stock and pay your executives large salaries with massive stock options.’ In the old days we had over 250 guys in construction and maintenance staying on top of pole change outs, system upgrades, …




Letter Re: The Fragility of the US Power Grid

James: An article posted on 10/16 on Internet Evolution has some sobering thoughts on the state of network security of the US power grid. It is written by Ira Winkler, a former NSA analyst and current security expert. His prognosis: “the power grid remains incredibly vulnerable.” Keep up the good work, – MP JWR Replies: In my writings, I often refer to the national power grids (there are actually three, eastern and western, and Texas) as the lynchpins of our modern societal infrastructure. Any interruption for more than a few weeks could precipitate a societal collapse. There is just so …




Letter Re: Phone Line Power for Emergencies

Mr. Rawles, I found this web page interesting: Free Hidden Electricity. Essentially this site has provided some basic information on how to tap the small amount of electricity available in our land lines to use for charging batteries or powering a lamp should the power go out (and not the phones) in a small emergency scenario. Within the discussions that follow the post are some legal and contractual concerns and a link to a retail lamp product you can currently purchase for this application. – Tanker JWR Replies: There are some ethical issues raised by this Instructable video, since telephone …




Letter Re: Home Alcohol Distillation

Jim– I have been fascinated by the material in the book “Alcohol Can Be a Gas!”. My first walk-through was a bit disappointing because of what I thought was a lot of fluff until I got to how to use alcohol as a fuel. Then I went back and read about distilling alcohol. Then I realized the author was saying alcohol is a by-product (he uses the term “co-product” to show all the products have value). Then he explains how a small farm operation could be self-sustaining, power, heat, fuel and food. Sounds like a survivalist’s dream. I’m anxious to …




Two Letters Re: Betavoltaic Batteries

Jim, Here is an article describing the challenges associated with betavoltaic batteries. The recent buzz over the 30 year battery, while intriguing, is overly optimistic. As stated in the article I linked to, betavoltaics currently have low efficiency, require heavy shielding, and the energy absorption media tends to degrade due to the high energy bombardment. I think it would be great if they could overcome these issues, but it looks like it may be 30 years before we see anything like a 30 year battery. – Mark D. in Utah Mr Rawles, Firstly I would like to say that after …




Letter Re: Low Light Shooting Techniques

Mr. Rawles: Anyone who carries a sidearm for protection should watch these three videos by Surefire: One Two Three. The first one covers principle of using light and flashlights to your advantage. It also discusses the Harries and Rogers Surefire techniques for shooting and advantages and disadvantages of both. The second one covers the FBI and neck index methods of shooting. The last covers clearing techniques in a building. I personally don’t like the Rogers Surefire technique because it requires a specific flashlight and will not work if the switch is not properly adjusted. – Bill N.




Two Letters Re: Lantern Battery Disassembly

Jim: On Saturday 22 September 2007, you posted a web link from T.A. in Indiana for a video on how to take apart a lantern battery and get 32 AA batteries out of it. I tried that with a heavy duty Ray-O-Vac and it had four cells approximately the diameter of C cell batteries but longer. Before people stock up on 6-volt lantern batteries thinking they will break down for AA batteries, they need to disassemble the brand they intend to buy to see how it is put together. The battery in the video appeared to be a bargain brand …




Letter Re: Les Stroud (aka “Survivorman”) Off-Grid Living Videos

James, I’m not sure if you’ve mentioned this series before, but on YouTube there is a video series called “Off the Grid” hosted by Les Stroud of Survivorman fame. He moves his family out of the city and into the country in search of an off-the-grid home and lifestyle. It’s a fairly realistic look and (I think) good introduction to what it would take to make the jump to living in the country and self-sufficiently. The other videos in the series can be found linked from the first page, or just search for “Off the Grid”. Hope you enjoy this, …




A Trip to the Yucatan–Observations of Mayan Primitive Living, by Michael G.

First, a preface on my background: I can’t decide if I should be a Cassandra (Sunspot cycle, Peak Oil, suitcase Nukes, Mayan Calendar mythology) or a Pollyanna (Y2K Flop, Heaven’s Gate, 2003 Hindu prediction Flop, and the 6-6-06 Flop; not to mention all of the countless predictions of the beginning of the “Time of Jacob’s Trouble,” rapture, et cetera, that hucksters and zealots have hawked for thousands of years). I believe whatever happens will happen and be over very shortly, and it will either leave us relatively unharmed or (given that I live in a city and work at an …




Letter Re: Advice on Compact Solar-Powered Refrigerators for Insulin

Sir: I am a Type 2 diabetic. I think that diabetics like me, and even more so Type 1s (those with onset in childhood) will be at particular risk in the event of a catastrophe, whether it is localized, national, or global. What is your recommendation for a method to keep insulin refrigerated in a long term so-called “Grid Down” situation? A solar powered fridge? Thanks, – Ron in Alabama JWR Replies: I recommend the Engel brand 12 VDC refrigerators sold by Safecastle. A modest-size photovoltaic power system, such as the 520 watt 4-panel packaged “cabin” system produced by Ready …




Letter Re: Suburban Survival

Hi Jim and Family, I truly enjoy reading your survival blog and learn from it daily and weekly. However I believe you are skipping over a topic that would benefit your readers….most of your readers. I would think that most of your readers who check out and read your site on a daily basis do not have a remote retreat in Idaho, Montana, Nevada, Utah, or Wyoming. Most of your readers I’m sure live like me in American Suburbs, trapped and looking for a way to get out but in the mean time prepping for what we all know is …




Letter Re: The Importance of Stocking Up on Batteries

James: I have been corresponding with an infantry soldier (E-6 [pay grade]) in Iraq named Ray that I met through AnySoldier.com. BTW, thanks for running that free ad for them on SurvivalBlog. All those “forgotten” soldiers need our real support–not just a “Support Our Troops” yellow ribbon magnet on the backs of our cars. In the last 8 or 9 months I have sent more than 30 “care packages” in [Priority Mail] Flat Rate boxes to [AnySoldier.com addressees in] Iraq and Afghanistan. In our e-mails, one of the things that Ray mentioned a couple of times really impressed me: It …




Letter Re: Useful LifeHacker Articles

Sir: A recent entry on your blog from ‘Tanker’ gave the link to a video on the Lifehacker web site. The last video he mentioned was made by a poster named KipKay. I have been a fan of KipKay’s for several months. He posts regularly on Metacafe.com. Incidentally, for each video he is paid and he has made approximately $55,000 from his creations. He has several videos that may be of interest to your audience. Below are the links and a brief description of each. Please decide if any of these merit inclusion on your blog. His official web site …




Letter Re: Useful LifeHacker Articles

Mr. Rawles: There are so many great and not-so-great ideas on the LifeHacker site including this one I found showing you how to use C cell batteries in place of a D cell compartment in an emergency situation: There are some other interesting things on this site like creating make-shift air conditioning systems using cold well water (others have made emergency air conditioners using beverage coolers, fans and copper coils): DIY Heat Exchanger and Make Your Own Air Conditioner. There is this one showing you how someone made hand washing more efficient while filling the tank of his toilet. [JWR …




Letter Re: Power Takeoff (PTO) Generators?

Jim: A short comment on using any power source without a governor to drive a generator. While it will work, it will not maintain a constant voltage or frequency under varying loads. I am 69 years old and have watched people build “tractors,buzz saws, water pumps etc” over the last 60 years using car or truck engines. Usually with very little luck. A tractor has a decent governor and will maintain a near constant RPM from about 10 % to 100 % load. Old tractors often used oil pressure to control RPM, don’t know about the modern ones as mine …
