A Simple Off-the-Shelf Solar Power System and Off-Grid Power Tools, by K. in Texas

This article is written for those who have no experience with solar power and would like to set up a simple beginner system. I have been using this system for over a year and have found it to be efficient. My goal was to put together a system which is easy to use and does not require a lot of technical knowledge. EQUIPMENT LIST: 1. BatteryMinder #SCC-015 Solar Charger 12 volt with 15 watt solar panel ($150 from Northern Tool and Supply) 2. BatteryMinder #BC2410 battery clip assembly ($10 from Northern Tool and Supply) 3. Interstate Marine/RV 12 volt battery …


Letter Re: Suggestions on LED Flashlights

Mr. Rawles, Just a suggestion about something you and your readers might be interested in. I’m not affiliated with the vendor in any way, just a very satisfied customer. 4Sevens‘ 2-AA Quark light is good for 30 days continuous on low, and a couple of hours at 200 lumens. These are by far the best LED lights on the market at this time. I hang around the flashlight-nerd subculture, and have 4Sevens lights in all my survival packs. Obviously, you can recharge LSD AA lights with solar chargers, and they’ll run off of regular AA and lithium AA batteries too. …


Letter Re: An “Energy-Independent” Village in Germany

Mr. Rawles: As an engineer interested in long term sustainability I was most interested in the item from Troy H. mentioning Juhnde, Germany. I took a look at their web site and ran the numbers to look at whether such an installation is commercially viable. The capital costs listed were EU 5,400,000 or about USD $7,900,000 at present exchange rates; It’s not clear when the overall system was constructed but the hot water pipeline system was built around 2005. Apparently, and I will have to look into this further, all of the capital costs were from public funds. This translates …


Two Letter Re: Some Observations on Fortifications Versus Camouflaged Retreats

James: Just a quick observation about the wisdom of sheltering in a missile base or some other Cold War-era fortification. While Chris is correct that history demonstrates that fortifications can and will be breached by enemy forces with the resources and determination to maintain a well-conceived siege, I question whether after TEOTWAWKI the marauders most likely to be challenging such a retreat will have the resources to see a siege through to a successful conclusion. Presumably, the scarcity of resources is precisely what would make a fortress such an inviting target. Unlike the armies that successfully overran ancient fortifications, there …


Letter Re: Some Observations on Fortifications Versus Camouflaged Retreats

Last night I watched Jesse Ventura’s “Conspiracy Theory” show which centered around the government’s cover up of the coming 2012 scenario. The show featured people converting missile silos to survival bunkers. Historical precedent will quickly point out a glaring problem with this approach. Consider that relative to the technological level of their day, European castles were more heavily fortified than any bunker being built today (by virtue of the fact that your average monarch of Medieval times had far more resources available than anybody seeking to build a shelter). Still, no castle ever withstood siege indefinitely. No matter how much …


A Preparedness Plan for a Single Woman With Children

I’ve been reading SurvivalBlog for almost a year.  I am thankful for the advice that I receive each day.  I have had a “be prepared” attitude for about 30 years, although the past two years have thrown several speed bumps and roadblocks my way.  Two years ago my son and his family were in a life threatening accident.  I spent almost every penny I had saved toward retirement to help my daughter-in-law recover.  This year I fought for and won custody of three of my grandchildren from my daughter.  So now, instead of planning for TEOTWAWKI for just myself, a …


Letter Re: Well, Well–An Amazing Find

Dear Mr. Rawles: I have owned my retreat for some years and as unbelievable as it may sound, I found a water well that I didn’t know I had. When I bought the land in the 1990s, I knew that there had been an old house there at one time, but assumed that they had either used a cistern, or drew water from the stream that runs through the property. However, I found the well. It had an old Gould’s 1HP pump at the end of 120 ft. of 2″ galvanized pipe. The well had been capped for years, or …


Letter Re: Photovoltaic Pathway Lights for Emergency Lighting

Dear Jim: First, thank you for your informative site. I know you`ve helped me, and many others fill in the gaps in knowledge for preparation for times to come. I live just three miles from the San Andreas Fault , so even if the Schumer doesn`t hit the fan, “the big one” could come at any time. Thus I`ve been prepping for many years, but it was a wind storm that helped me think of this trick. The local utility power recently went down and the girls broke out some candles,while I grabbed a couple of battery powered lanterns. Candles …


Letter Re: Covert Home Power for When The Grids Go Down

Hello, I just wanted to pass along a link to a company that sells new made in USA alternators for common vehicles, 190 up to 270 amps, and brackets and belts to run duals. the base model 190 amp puts out a 130 amps at idle ( factory puts out maybe 60 amps, on a full size truck) these things look built to last, and would run an inverter a lot better than stock, never mind worrying about burning out your electrical system. I will be getting one of these soon! As usual just an interested consumer, not affiliated with …


Three Letters Re: Covert Home Power for When The Grids Go Down

Sir: I am not an electrician, and I set as system like this up at my house three years ago. It kept our food cold, and the house tolerably warm for three days when the power was out. But I endorse a couple of important differences. First, letting your car run at idle will run down your battery. The alternator doesn’t reach full output at low RPMs, so you need to kick up the throttle a little bit. How much will depend on your car. I watch the volt-meter built into the inverter, and set the engine at about 1,500 …


Five Letters Re: Covert Home Power for When The Grid Goes Down

JWR – The article written by Tom H. contains some dangerous advice and overlooks some important issues. He wrote: “Next, cut the receptacle end (female) off the 120 VAC extension cord and install the replacement 120 VAC plug (male) to the cord. Make sure it’s wired correctly. (Black to black, white to white and green to green). You will now have a cord with a [male] plug on both ends.” Such a modified power cord [commonly called a “disaster cord” or more aptly a “suicide cord’] is extremely dangerous, and should never be made. If one end is plugged into …


Covert Home Power for When The Grids Go Down, by Tom H.

There is much written about the Power Grids going down (for whatever reason) and how to prepare for that event. Recommendations have been made for the installation of a generator, solar panels, battery banks, inverters, automatic system switches, on and on and on. These systems range from a simple inexpensive plug in inverter for your car 12 VDC socket (which may power a lap top or a cell phone battery charger) to an extremely complicated self-sufficient system that will operate your whole house. The simple fact is that most people will not install such systems for a variety of reasons …


Two Letters Re: Generator Experiences During a Recent Nor’easter

Jim: The letter about Generators today inspired me to write this email. I have owned generators for around 20 years for emergency backup and portable power uses. I use my generator primarily for powering sound equipment in the field. As a result I looked for a quiet generator. The very quiet generators all run at 1,800 RPM, but it is expensive to make a generator that runs slow and quiet, and the affordable portable generators all seem to run at 3,600 RPM. When I purchased my current generator 10 years ago, Coleman had just started using the Briggs and Stratton …


Letter Re: Generator Experiences During a Recent Nor’easter

Greetings Mr. Rawles, I just wanted to pass along a quick reminder to your readers who took the time and expense to buy a backup generator, but haven’t taken the time to periodically test and maintain it. Here in southeastern Virginia, we are still recovering from what was called the “Atlantic Assault” by the hyperventilating reporters on the Weather Channel. To be fair, though, this was indeed a whopper of a Nor’easter that gave us flooding only a foot or so less than Hurricane Isabel in 2003. We lost power the evening of November 12, but luckily got it back …


From David in Israel: Off Grid Alternatives to Utility-Supplied Electricity

James One of the most troubling things I see when speaking to people about going off grid is how badly they want to keep all of their electrical appliances and just spend many thousands of dollars on a battery bank more appropriate for a U-boat and solar cells or generators to keep them topped off. Having had a minor role in a micro-satellite system design proposal one thing you learn when confronted by limited power supply is to either economize or do without. The appliances you own for on grid use are not efficient. They are built to be inexpensive …
