Two Letters Re: Thermoelectric Generators for Wood and Coal Stoves

James, To follow up on an earlier letter and your reply, Thermoelectric Generators (TEGs) work by generating power from the movement of heat from the hot side to the cold side of a dissimilar metal junction. An important consideration is that TEGs can become heat saturated or worse if you can melt your TEG, so don’t just throw it in the middle of a fire! I followed a design from “The Boy Electrician” by Alfred P Morgan 1913. It uses German silver wire and copper wire with hammered junctions, there are better combinations but this was easy to get. It …


Letter Re: EMP Grounding Straps and Cables (Updated)

Good Morning Sir, My question pertains to a February 24, 2010 blog post, where there was mentioned an EMP ground for one’s vehicle. This is the first I have heard of a ground wire for today’s vehicles that would prevent electronics from being damaged. Is this true sir? Thanks for providing us all the education to survive. – Tim S. JWR Replies: A grounding strap offers only marginal EMP protection for a vehicle. The type that were mentioned are the sort that you can see used on many trucks, especially fuel delivery trucks, where the concern is a buildup of …


Letter Re: Thermoelectric Generators for Wood and Coal Stoves

Hello You folks do an outstanding job of informing those who want to learn! I was just wondering if there was information about homemade thermocouples out there. I was watching my woodburner last night and it has one of those little fans sitting on top that start to spin when they get hot and was wondering if I could find plans to build a bigger version of the thermocouple. I envision something about the size of a briefcase . In a grid down situation this would be set on top the woodburner that would be going for heat and cooking …


Letter Re: Charcoal Making Via Wood Gasification

James, Just to note, the process and apparatus which Dan in Oklahoma described for making charcoal also goes by the name of “Gasifier.” The venting of the volatile gases in the wood can be put to several purposes, to include running carburetor engines on generators and trucks. The Russians used this system extensively for rear area operations as liquid petrol was priority for front line vehicles and aircraft. They would fire them up at breakfast time and run them all day. Me thinks that today’s breakfast was probably cooked on yesterdays driving around…the charcoal. Some examples of delivery trucks in …


The Home Foundry, Metal Casting – Part 3, by Dan in Oklahoma

Forge Fuel & Homemade Charcoal The aluminum melting forge is fueled by hardwood charcoal. To begin making charcoal you are going to need 2 steel barrels. One standard size 55 gallon drum will serve as your outer barrel, the second barrel is a little more difficult to acquire. The inner barrel or actual charcoal out gassing barrel needs to be small enough to fit inside the 55 gallon barrel. The smaller barrel also must have a lid that can be locked in place during the cooking and removed later to extract the charcoal. I was fortunate enough to find Military …


Incremental Preparedness: The Good, Better, Best Approach, by Jeff B.

For many, the idea of preparedness seems like an impossible undertaking. The amount of equipment and supplies needed is staggering. When I first came to the realization that I was under prepared, the gap between what I had and where I needed to be was too much for my public servant’s paycheck to bear. I would spend a lot of time discussing preparedness with a group that I would go shooting with, and all of these meetings would always gravitate to “which weapon do you plan for X meters?” or “how many rounds do you think I need for X …


Getting Prepared: From the Homestead to Living Off the Land

Introduction I currently do not fall in the category of the less than 1% of the population that can afford the real possibility of a “retreat” on 40+ acres, based on a Rawlesian criteria. However, I do have a solid brick house on 1.5 acres in a rural area on the southern plains. For the immediate future this will have to serve as my permanent abode. I have always had an interest in outdoor survival skills, and have lived, vacationed, and worked for extended periods of time in isolated outdoor camps while working “in the bush” with limited modern comforts. These …


Letter Re: A Shortage of Mantles for Aladdin Kerosene Lamps

Dear Jim, I was trying to buy an Aladdin Loxon Mantle #R-150 for my Aladdin kerosene lamp and found that all suppliers seemed to be out of stock. Even Lehman’s Hardware here in Ohio was out of stock and showing an April delivery. I spent some time searching and found some very expensive ones on eBay but that was all. I then did a search for “Aladdin mantle problems” and found a cached press release from the Aladdin company. It looks like we have a major problem for Aladdin Lamp owners. From a loyal reader, – Jay H. JWR Replies: …


Three Letters Re: Lessons Learned From an Ice Storm

Dear Editor: With regards to the battery powered carbon monoxide (CO) detector, I just want to second that. When my family went through the Nov. 2007 ice storm that took out the power to half of Oklahoma, we were running off our generator for two days. The first night I put it outside, but close to the house to help shelter it from winds. Our CO detector went off in the middle of the night. We ended up having the fire department come out and check things. It was determined that the CO came in through either the dryer vent, …


The “Power of Ten” Planning Model, by Sandkicker

This article has nothing to do with any special properties of the number ten, but rather refers to a progressive planning method based on the size of a problem. This is a way to organize thinking and planning for chaotic situations.   “If you fail to plan, you’ve planned to fail”.   It would be irresponsible to present any particular plan as suitable for everyone, however, these are some guidelines on how and why you should develop your own plans.  Why do I have the nerve to write this piece?   I’ve been in the middle of more than one “adventure”… and in …


Two Letters Re: Lessons Learned from the Oklahoma Ice Storm of 2010

Dear Editor: The Oklahoma Ice Storm of 2010 is now melting away and as usual there were lessons learned.   Many of these should have been “known” before but we are never as prepared as we should be.  In that vein I am going to rehash several things that went right, a few that went wrong, and others that we can improve on the next time that “life as usual” is not. First, the setting: I live in Southwestern Oklahoma and have been here for almost three years.  About January 22nd we started getting word of an impending ice/snow storm scheduled …


Lessons Learned From an Ice Storm, by G. in the Zarks

While watching the local weather over the last few days, it has become apparent that a winter storm is heading for our part of the world, bringing with it the distinct possibility of not just snow, but significant amounts of ice. As I pondered this, it brought to mind our recent experiences with ice storms over the last few years, most notably in January 2007. I thought some of our “lessons learned” were worth sharing with others. We had been blessed with several years of reasonably mild winters leading up to the 2007 storm. Unfortunately, the good times often seem …


Letter Re: I Thought that I Was Ready!

I have just returned to my house after 6 days without power. I Thought I was ready. I had plenty of beans, Band-Aids, bullion and bullets. What I didn’t have was the stuff I needed to get through the first week of a massive power outage. We still had water, even though I had an additional 50 gallons of fresh, treated water for myself, The Beautiful Wife (TBW) and the pets. We had enough short term food that we were able to provide a chili meal for some of our friends and coworkers that were doing without. We had more …


Letter Re: The Rocket Stove, Refined

Several times in items I’ve sent out or in live presentations I’ve mentioned the “Rocket Stove,” a simple stove concept worked on over the last 20 years or so at the Aprovecho Research Center in Cottage Grove, Oregon (and elsewhere) by Larry Winiarski and others. The goal in refining this stove was to create a wood or charcoal – burning stove that would use the absolute minimum amount of widely available fuel to boil a given amount of water, thus minimizing fuel use and waste, and also smoke that could contribute to health issues for those tending, or in proximity …


Letter Re: Building a Supply of Long-Burning Candles

Dear James, I recently was walking through Ikea with my wife here in Minneapolis and came upon a candle sale. They are currently having a sale on red 8 inch, Unscented Christmas candles rated at 70 hours for 99 cents. I promptly filled the cart with 40 or about 2,800 hours worth of candlelight for 39 dollars. Not wanting to recommend anything I had not already tried I promptly lit one to see how long it would last and right now it is still burning on hour 85 – will probably be done between 90 and 100 hours. Thought your …
