Letter Re: Running a Laptop from a Jump Pack in a Short Term Emergency

JWR: Through a minor power disruption event, I made some discoveries that I thought I would share. A laptop computer can be run by an inverter of proper size. A laptop can be powered by a jump pack with a 12 VDC power port. The jump box can be recharged by a hand crank 12 VDC generator. We were able to continue e-mail and business communications, since the wireless towers are generator backup powered. This is good to know in local or short term disasters. – JG JWR Replies: Thanks for mentioning that topic. In my experience, running a laptop …


Fuel Storage for Survival Retreats, by Flighter

The world runs on petroleum. Imagine a post-apocalyptic period when the local gas station is closed, and has been for two years. How will you carry out your daily activities? Generate electricity? Pump water? Plow your garden, or fields? All of these can be done by hand, and have been for thousands of years. Modern life has given us tools to help with these chores, and we can store the tools, and the food for them, for quite awhile. Gasoline, diesel fuel, jet fuel, kerosene, Coleman® fuel, and other petroleum products – all can be stored. For long term survival …


Letter Re: Question on LEDs and EMP

Hi Jim: Your blog is the best I’ve come across on the Internet. Very useful information. Regarding the subject of [Electromagnetic Pulse] EMP, are the new Light Emitting Diode (LED) flashlights more, or less immune to EMP than those using conventional incandescent bulbs? Modern solid-state circuitry is in grave danger of terminal damage in the event of an EMP occurrence. LEDs are composed of a semiconductor junction, similar to transistors and integrated circuits. Do modern LED flashlights have enough of the right characteristics to pick up sufficient EMP burst energy and become permanently useless? Your comments please, and thank you. …


Letter Re: Advice on Where to Learn Practical, Tactical Skills

1

Dear Jim: As my confidence in the dollar depreciates and my desire for skills increases, I’m wanting to convert FRNs into hands-on knowledge. What weeknight or weekend workshops would you recommend? Are there any places where you can learn Army Ranger skills without joining the military? Animal husbandry, and so on? – Spencer JWR Replies: There is a tremendous wealth of free or low-cost classes available–enough to keep you busy every weekend of the year if you are willing to drive a distance. If you have time and just a bit of money, you can get some very well-rounded training …


Nuclear, Chemical or Biological Disaster Preparedness, by Brian A.

One of the recent phrases the media has used almost to exhaustion is, “dirty” bomb. A dirty bomb, or radiological dispersion device (RDD) is basically an explosive device with some element of radioactivity attached, or some other means of distributing radioactive particulate matter. When detonated, it releases radiation in the form of dust or debris, which is harmful mostly when inhaled, or introduced into the body by other means, (eyes, open cuts, etc.). The main terror use of such a weapon would be to contaminate emergency services workers responding to the initial blast. In the 1990s, Chechen rebels reportedly placed …


Letter Re: Lessons From an Unexpected Grid Down Weekend

Hi Jim, We just had a bout with Mother Nature and lost power which appeared at first to be for some time. I am happy to report that my “list” generated from this un-expected “grid-down” weekend was very very very short. I attribute this success and wonderful feeling to what I have gleaned from your publications, SurvivalBlog, and a few very good friends! We were without power for about 40 hours and really only had two “needs”. I was actually “disappointed” when the power came back on. J Oh, and we did not use the power generation until hour 38 …


Poll Results: Best Occupations for Both Before and After TEOTWAWKI

In no particular order, the following are the first batch of responses to my poll question on the best occupations or home businesses for both before and after TEOTWAWKI: Locksmith/Home security systems installer/repairman — Beekeeping Small scale vegetable gardening. Growing herbs (medicinal) — 1) Electricity: a. Recharge batteries for folks, rebuild the bad batteries, and lots of folks don’t know squat about electricity for lighting, etc. Got several methods: Solar, miscellaneous generators powered by hand, animal, wind and even the old one lung gas engine with that darn heavy flywheel. b. Also use the above for communications when there aren’t …


Two Letters Re Converting A Gasoline Engine Generator Set to Propane

Hi Jim, Regarding the thread on converting generators to propane, last year I installed a tri-fuel conversion kit on my 7.5 KW generator, that has a Honda engine. [Since the conversion] it works perfectly and [the conversion kit] was very easy to install. If the [grid] power goes out, I can switch it to the piped-in natural gas and if that goes out, I can either use propane or gasoline. I also got an inexpensive solar trickle charger and connected that to the battery, so that the battery is always fully charged. Best Regards, – Kurt JWR Replies: I consider …


Letter Re: Observations on the Recent Missouri Ice Storm

Mr. Rawles, I live in Southwestern Missouri. Did you followed the ice storm that buried the Midwest? We got hit pretty hard. We get hit hard every four or five years. Which brings me to my point. I have never seen so many unprepared people in all my life. After day two of the ice storm power was out (for a month in a lot of places like Springfield). There were no gas cans to be found at any store. Batteries, disposable propane bottles, flashlights, milk, and meat were missing from the shelves of every store. Even Wally World [Wal-Mart] …


Letter Re: Streamlight Incandescent/LED Combo Flashlight

Dear Jim, I just picked up a Streamlight Twin Task 3C from Flashlight Outlet. They were set up at the Indy 1500 Gun and Knife Show near my tables, and are great people to deal with. This light is solidly machined from aluminum, small enough for use, large enough to make a handy baton, and gets 1 hour at 57 lumens of xenon bulb, 100 hours at 21 lumens of LED, and has a laser pointer. I didn’t really need the laser pointer, but it was $1 cheaper with it than the version without. It takes 3 common C cells. …


Letter Re: Observations on the Recent Oklahoma Ice Storm

Jim: Well, I just got back online. I had to go up to the roof and thaw the wireless [Internet] antenna with a heat gun. It seems the ice grounds out the antenna. It was an easy fix with my heat gun for heat shrink tubing. More precipitation is on the way but colder. It will probably just be snow. We never lost power but were ready anyway. I have friends with no power and they have been without power for days and no idea when it will be back on. The further out you live, the less chance of …


Letter Re: First Hand Observations on the Recent Pacific Northwest Wind Storm

Background: I am an 11 year veteran peace officer and survivalist, or in more politically correct terminology, a POP – Preparedness Oriented Person. I work in a moderate sized city in the Seattle area. On 14-15 December, the Tacoma-Seattle-Everett metropolitan area suffered one of the most deadly and damaging windstorms in recorded history. The storm easily eclipsed the last major deadly blow on Inaugural Day, 1993. That storm had been identified as a “once in a century” type storm. At the peak, over 1 million people did not have power. This storm was modeled and forecasted with accuracy five days …


Letter Re Maglite Flashlight LED Conversions

I just purchased a Maglite Brand LED conversion for a two D-cell Maglite.[These replace the original filament light bulb holding “head” of the flashlight.] It was $20 at a Lowe’s [hardware store] in Oregon, with no sales tax. These take only three minutes to install. The focus feature still works great, but the best feature is that it is very bright, almost blue/white. Much better battery life and outstanding bulb life, not affected by dropping. All in all, a very good conversion for one of the best lights made. They also have them for 3 D-cell , and 4 D-cell …


Letter Re: Some Good Things Prompted By SurvivalBlog

Jim, The following are some things SurvivalBlog.com has prompted me to do since I began reading it: I’ve had no debt for 20 years, but my meager holdings are now about 1/3 precious metals. Is lead considered a precious metal? 🙂 My freezer is full of elk, whitetail deer, and caribou. I added to my long-term foods during your Safecastle special, but I’m now reviewing the viability of my existing stocks. Like the realtor’s mantra of “location, location, location”, a survivalist’s creed should be “Rotate, rotate, rotate. “ A 10 KW Generac generator is ready to be wired to my …


Letter Re: Mobile Solar Power Systems

JWR, Here’s an item some of your readers may be interested in, Mobile Solar Power, it’s a mobile solar power setup and looks like it would fit in with a number of different scenarios. I spoke with the owner a few days ago and he said he will size the equipment to fit your needs/specifications. It appears to be made with high quality equipment and the owner said the batteries have a 10 year warranty, but with care, may last up to 15 years, otherwise the remainder of the equipment should have a life much longer than that. This solar …
