Letter Re: 12 VDC Wall Outlets and Power Cord Connections

Jim, For anyone using 12 VDC in their vehicle or home, you should strongly consider using Anderson Power Poles. Compared to the standard cigarette lighter plug, these are far more reliable and safer. (Cigarette lighter plugs have no uniform rating, and can melt if used for high [current] load applications.) These connectors come in ratings from 30 Amps (A) to 350 Amps. The 30A size is the de-facto standard for Ham radio operators now, and the larger sizes are what you see used for things like large battery racks in computer rooms and tow truck jumper cables. They are easy …


Four Letters Re: Prowlers and Lighting

James: The subject of handheld lights is as long as it is wide. Ask 20 people what is best, get 40 answers and recommendations! As with many things, today we live in a great time for flashlight technology. My recommendation is to immerse yourself in www.candlepowerforums.com. Some guys there are truly on the cutting edge of lights. Some of the modified lights are incredible. Have fun and enjoy a winter’s worth of reading. – Straightblast   Jim: Just enjoying a last respite prior to retiring in my mountaintop isolated home and read the letter on Prowlers and Lighting at SurvivalBlog. …


Letter Re: MURS Radios, Dakota Alerts, and PIR Sensors

Jim, I for one I’m very happy that your novel “Patriots” back in print. For a long time I gave this book away to friends who I thought might like it, and to some whom I wanted to “feel out” as to whether they thought preparedness was a good idea. I had to stop this of course when your book went out of print, and the cost went skyward. Now I can stock up again. Also I wanted to thank you for turning me on to MURS Radios. I just made an order with Rob, and will be making another …


Letter Re: Clothes Washing Without Grid Power

Shalom Jim: Recently my wife and I have started looking to replace our old [clothes] washer and dryer machines with something more energy-efficient. Since we plan on converting to solar photovoltaic panels in the future what do you suggest we do now? 1.) Lehman’s sells an AC +/ DC operated washer. Is this (DC) feature conducive to solar technology? 2.) What are you and your family doing for your clothes washing needs? B’Shem Yahshua HaMoshiach (In the Name of Yahsua the Messiah) – Dr. Sidney Zweibel   JWR Replies: 1.) With a PV power system, using a DC motor clothes …


Letter Re: Enlightened Survivalism Article in The Energy Bulletin

Jim, The comments in today’s SurvivalBlog concerning my ‘Enlightened Survivalism’ article that was posted on the Energy Bulletin that ‘this more likely qualifies as preaching to the choir’ is exactly why the article was not sent to yourself for posting on SurvivalBlog. I tried ‘preaching to the choir’ as you put it with my post to you ‘Considerations for Longer Term Survival’ that you posted on Wednesday, December 21, 2005. It would seem that many have still not really got to grips with its contents particularly: ‘What about food when the “Year’s Food Supply” is gone? What about your water …


Two Letters Re: Product Review of the MURS Alert Motion Detector/Alarm From Dakota Alert

Mr. Rawles: My friends and I have been using the MURS band for some time. It generally has better range than FRS/GMRS and is much less crowded. There is an interesting product available that works with these radios as a sort of “perimeter alarm” system. The MURS Alert from Dakota Alert is a small, weatherproof box that combines a PIR motion detector with a 1-watt MURS transmitter and a voice module. It uses six size AA batteries and has an advertised six month battery life. The unit is placed near a road, driveway, trail, etc and set up. When a …


Letter Re: Source for AAA to D Cell Battery Upsizers/Adapters

Jim, I trust all is well with you and yours. I recently found a source for a battery adapter. There are a lot of products that will take one AA cell and make a D cell battery. I found somebody makes an adapter that uses two size AA cells to make a D cell battery. (Twice as much battery life.) I’ve even seen a reference to some adapters that use three AA batteries. (That would be neat.) I recently received and tested C cell and D cell upsizers. The C cell is the common type, one AA battery makes one …


Letter Re: An Early Snowstorm in Western New York

Well, mother nature really gave it to them this week. There were 24 inches of snow dumped on us in about 24 hours. That, and the trees still had most of their leaves still intact. That just made more surface for the snow to stick, and it was the wettest imaginable snow you have ever seen. I’m writing this on Sunday. The power has been out since about 5 P.M. on Friday, and they are saying it won’t all be back on till next weekend. I didn’t lose my power, since I live north of the worst of it. I …


Letter Re: 12VDC LED Christmas Lights for Emergency Lighting

Jim: On a lark, I order two strings of these 12 VDC LED sort-of Christmas lights. I ordered one string of blue for the porch (really easy on Night Adapted Eyes and one string of white. Wow! Really neat. Low current (i.e.: extremely low power consumption) and just plain handy. I’m just guessing but I figure two strings would run for 6 weeks on a fully charged car battery. Nice for those “loss of electricity days/nights” and a lot cheaper than the camping/emergency lighting systems. I think it is a reasonable purchase.Best Regards, – The Army Aviator


Two Letters Re: The Coming Energy Crisis: Hubbert’s Peak Or Not–Be Prepared!

Dear Jim: Let’s face it, most of our energy shortfalls are completely self-imposed. Gone are the days of the 1950s when generations looked to and planned for the future, built infrastructure and power plants for the grand cities that would one day be. Now we in the US haven’t built a new nuclear power plant since the Three Mile Island incident. We’ve turned against coal even though we have hundreds and hundreds of years worth of the stuff or more. Ted Kennedy won’t let windmills go up any more since they wouldn’t look nice to Ocean front property owners in …


The Coming Energy Crisis: Hubbert’s Peak Or Not–Be Prepared!

There has been a lot of ink spilled in recent years, debating the Hubbert’s Peak (“Peak Oil”) theory. FWIW, I am a believer in global oil depletion, but I think that those in the “Peak Oil” crowd are about 20 to 25 years too early in their predictions. In my estimation we cannot depend on the slow-moving bureaucracies of national governments to rescue us from the coming energy crisis. Even if we were t overcome the problem in the First World, the second World and the Third World–with less money available for massive crash programs and probably with a more …


Six Letters Re: The Ethanol Debate

Sir: Regarding ethanol, the amount of fossil fuel or equivalent slave labor wage work make ethanol driving a exclusive privilege of the wealthy. Brazil has the world’s highest percentage ethanol from sugar cane for motor fuel. US use of current corn ethanol processes are petroleum negative and only feasible due to massive taxpayer subsidies. If the readers of SurvivalBlog are expecting to have motor power in the age of ethanol I realistically suggest keeping down to a small displacement engine motorbike and maybe a chainsaw. Electricity is much higher watt per acre from water solar or wind and bicycle horse …


Letter Re: Recommendations on Solar Battery Chargers?

Jim, Could you maybe put the word out as to where to find a good reasonably priced solar panel for charging Ni-MH batteries? Thanks. – Gung Ho JWR Replies: I recommend Ready Made Resources for solar battery chargers, although there are several other Internet vendors that sell comparable products. But I can vouch for RMR’s reliability and customer service. If you are on a budget RMR’s compact Universal Solar Charger at under $28 is the way to go. But this model charges just two batteries at a time. If you have a bigger budget, any of the Global Solar brand …


Letter Re: Rechargeable Batteries for FRS and GMRS Radios

Jim, Just a note on the popular two-way handheld radios sold in many big box and sporting goods stores in the US. I have been trying to standardize my rechargeable batteries for these little handhelds to the ubiquitous AAs since my scanners and many of our other small lights and some gear run on them. I have four older Motorolas from 3-to-5 years ago for our use around the farm and when traveling with more than one vehicle for any distance. First, I noticed that there has been a gradual switch for these FRS/GMRS radios that once took AAs you …


Letter Re: Solar Panel Shortage — Caused By Oil Price Shock

Hi Jim. Just a quick one on [photovoltaic] solar panels. My brother and I had to put an order in for three 80 Watt Sharp brand panels that are usually just sitting on the shelf here at a major distributor. A container full arrives in two weeks but it’s already sold out! We have to wait a month. I did a little investigation with Google and found that the shortage is worldwide, is due to people, mostly Europeans, gearing up due to energy/oil cost. Silicon [photovoltaic panel] demand is beginning to outstrip supply and the foundries are running at maximum …
