Letter Re: Constructing a High Efficiency (Low Current Draw) Refrigerator

Hi Jim There was an article on your blog a few weeks ago about converting a chest freezer into a low wattage refrigerator. I decided to make one of these as it is a great idea. I purchased a 7 cu ft freezer at Home Depot for $200 and then bought this device (the Johnson model) and that was all that I needed. I first used it as a freezer and put a Kill A Watt [current monitor] on it. It averaged 1.13 KW per 24 hours. I then used the thermostat and used it as a refrigerator and tested …


Letter Re: Photovoltaic Versus Diesel Power Generation for Retreats

Hi Jim, I was a reader of Patriots before the [Y2K] rollover. Thank you!. Here in the Northern New England, I made the same calculations, and decided to stockpile off road diesel and kerosene. The other major component is used vegetable oil, usually available free from restaurants, who otherwise pay to have it hauled by a recycling outfit. My 20 h.p. Listeroid diesel runs fine on waste vegetable oil (WVO). So does the 13hp Hatz backup generator, along with an ’85 Diesel Suburban and ’82 Diesel Rabbit. Filter the big stuff out using more coarse filters like a pillowcase. Filter …


Letter Re: Photovoltaic Versus Diesel Power Generation for Homes and Retreats

Jim, I am taking the 10 Cent Challenge and have made a contribution. I have been reading SurvivalBlog for about a month and intend to keep making my contribution for the next foreseeable future..This is an awesome site. I have been wanting a solar array to add to my survival plan, According to the calculations I need to have the capacity to produce about 1KW adjusted to .75 KW. In order to adequately provide for my housing needs, minimal water pumping, lighting, small appliances, computer, phones, network, some TV, battery charging , fans for sleeping. We are in Mississippi along …


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 …


Letter Re: Advice on Diesel Vehicles–Motorcycles and ATVs?

Dear Mr. Rawles: I already had a diesel Ford tractor, so I took your advice and got a diesel pickup, and I’m shopping for a used [diesel] Mercedes. Those things run forever. And as my budget allows, I’ll also plan to buy a diesel generator to replace my gasoline backup generator. So now I have logistics problem: I have two types of fuel to store, since my motorcycle, Polaris ATV, and my Husqvarna chainsaw all use gasoline. Diesel stores way longer than gas. But I guess that there is no way to avoid having some gas vehicles and tools. JWR …


Letter Re: Potential Range of Nuclear Weapon EMP?

Mr. Rawles: I’m confused. Some things that I’ve read say that the maximum range of [nuclear weapon electromagnetic pulse] EMP is about 60 miles, but others say 200 or 250 miles. Which of them is right? Wouldn’t a terrorist bomb at ground level have shorter range EMP than a nuke touched off at high altitude or low orbit? (With a wider horizon.) Thanks, – Lance in Nebraska JWR Replies: You aren’t the first SurvivalBlog reader to ask about the greatest potential effective range of an EMP-optimized nuclear detonation. I first discussed this in SurvivalBlog back in October of 2005. The …


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 …


Letter Re: Three Liabilities Addressed: Refrigeration, Sanitation, and Fuel

Jim, This is in response to “Three Liabilities Addressed: Refrigeration, Sanitation, and Fuel” article [by James D.]: Refrigeration is only a big problem for survival when one makes poor choices and is dependent on obtaining fuel for a generator to power a typically inefficient refrigerator. Refrigeration is relatively easy if one has planned ahead and made the right investments in both refrigeration and power generation before a crisis when one can still get the required system components. Most refrigerators and freezers are inefficient, often using 500 to 1,000+ watts per hour. Choosing the right refrigerator, adding insulation to its exterior, …


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 Converting A Gasoline Engine Generator Set to Propane

Hi Jim, A friend just sent this note to me and I thought I should pass it on to the SurvivalBlog readers: I finished the generator conversion this weekend. I converted my generator from gasoline to propane. I had to order the big regulator (Garretson) from an online supplier. These are a ‘demand’ [feed] regulator and will only deliver propane if something is pulling on it. Once the engine is shut off, it quits delivering gas. I started by removing the gas tank and fittings, then stripped the carb down, removing everything that had anything to do with fuel delivery. …


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] …


Two Letters Re: Electric Golf Carts as a Retreat ATV Option

Dear Mr. Rawles, I have a few points to add to the golf cart idea. first, It is feasible [to convert an electric golf cart into a quasi-ATV.] I worked a a mechanic at a golf course. Power is power. Most carts use four 6 volt batteries [cabled] in series to make 24 volts. Second, some very necessary tools and parts for the job, many feet of battery cable, end fittings and a good swagger [–a cable terminal swaging tool.] Look for these at your nearest auto store. [JWR Adds: These tools are also available at most marine supply stores. …
