Three Letters Re: Small Scale Alternative Energy in Suburbia

Mr. Rawles: In a recent SurvivalBlog post, Alan W. wrote: “It has a 400w inverter with a modified sine wave output. During Hurricane Irene the only thing that I could get it to power was a standard lamp with an incandescent light bulb! It wouldn’t run tools or electronics.” I believe he is drawing the wrong conclusion from this experience. Instead of blaming the (admittedly inferior) “modified sine wave” inverter, he should have blamed himself for not testing his equipment before the emergency struck. I own a number of inexpensive inverters with “modified sine wave” ranging from 175 watt to …


Letter Re: Small Scale Alternative Energy in Suburbia

Sir: I had purchased two Schumacher brand Portable Power packs-essentially a [gel cell] battery with [just] an inverter without the extra buzzers and bells from a company that makes quality battery chargers.  It has a 400w inverter with a modified sine wave output.  During Hurricane Irene the only thing that I could get it to power was a standard lamp with an incandescent light bulb!  It wouldn’t run tools or electronics.  After some Internet research, I found that most units used the modified sine wave because it is a less expensive design.  Unfortunately, it may or may not supply power to the unit that …


Small Scale Alternative Energy in Suburbia, by David J.

The range of topics in prepping pretty much covers the spectrum of life, and all aspects tend to be connected, however, this article is mostly limited to my strategies to power my grid dependant, difficult to defend, suburban home when the grid is down, all the while on a limited budget.  No new, earth shattering, break through here, just a plan that uses lots of basics. My circumstances probably reflect a sizable demographic of the folks who are attempting to prepare for hard times in the suburbs.  A middle class male, married with 4 kids, living in a stick house, …


Letter Re: Coalbed Methane and Retreat Locale Selection

Mr. Rawles, I wanted to send a quick note that one option for a retreat’s power/heating needs could be met with a natural gas well on the property.  Here is a link to a map which shows coal bed methane areas in the United States.  If someone was so inclined, a well could produce natural gas for a retreat for as many as 100 years and allow for a completely independent fuel source which can be added to other sources such as wood stoves and the like.  Best Regards, – Jon H.


Lessons in OPSEC: Hurricane Irene Versus Hurricane Isabel, by Gonzo

In 2003 I lived in what can only be described as “The Hood” when Hurricane Isabel arrived. Today I find myself in a middle class neighborhood for Irene. The difference between the two and how my neighbors are handling these semi-SHTF scenarios gives a very instructive view of operational security (OPSEC) and its effects.  These two hurricanes came ashore about the same place and the same strength, but its two different worlds I have seen the aftermaths effects on. During Isabel I lived in one of the worst sections of Virginia Beach, the sort of place that other people who …


Letter Re: A Photovoltaic Lighting Option

Hi Jim, Just bought a bunch of these ‘underwater’ solar floodlights, from Northern Tool: Sunforce Solar Powered Underwater LED Floodlight, Item# 121178 They are very bright for a single LED and they will stay on until dawn if they get a full day’s charge. The light is more of a spot light and is better than most flashlights being able to light up over 60 feet away fairly well. These are great for low maintenance perimeter lighting and [unlike typical solar pathway lights,] are waterproof. Their batteries are NiMH AA cells and are replaceable. The lights plug into the panel …


Prepping: It’s Not Just for TEOTWAWKI, by Choctaw Prepper

In this day and age of being able to go to a store and get practically anything you would ever need or want, the concept of preparing for a disaster escapes some individuals.  The time of “Victory Gardens” and canning your surplus vegetables and fruits have fallen by the way side in our current culture.  Our society sees people storing vast amounts of food and supplies as paranoid because they are simply not accustomed with the practice, nor do they see the need.  Most people cannot conceive the idea that they can be left without food or water, or that …


Letter Re: Inverters for Disaster Preparedness

Jim: There have been several recent articles on UPS systems and inverters. Most of the current inverters use MOSFETs or similar sensitive solid state switching devices. These are the hardest stressed components of the inverter. Spares should be a consideration. In addition many modern inverters use custom chips that may not even be available now, so not at all after TEOTWAWKI. Consider this, inverters have been around for quite along time. The best design that I have worked with and designed circuitry for is the McMurray-Bedford inverter. It is a simple design that originally used thyratron tubes and later, SCRs. …


Letter Re: The Little Things

This experience was thought-provoking, and many of D.M.L.’s ideas were interesting.  But there were two ideas that have not been tested or proven, so at this point they are only ideas.  First, J-B Weldwill not repair a cracked Briggs & Stratton two piece fuel tank.  They are made of black HDPE, and there is no proper glue for that.  I have personal experience with this.  HDPE is heat welded when two pieces must be joined.  You have to determine your Briggs & Stratton model number and order a replacement gas tank from Amazon.com.  I got mine for my Briggs & …


The Little Things, by D.M.L.

So, you think you’re prepared? So did I. Until Hurricane Irene destroyed the infrastructure around here. The roads were blocked to all the local towns, all three routes out of here. If it wasn’t trees down, it was flooded, or power lines and poles leaned over the road in the ‘maybe’ zone (maybe you would hit them and maybe not, but why take a chance on thousands of volts? If not those, it was pieces of somebody’s house across the road. And this was only a Cat 1 storm? Sigh.   Before she hit, I, being confident that we were ‘prepped up’, …


Two Letters Re: Hurricane Irene Lessons Learned

Jim, I thought I’d share with you some thoughts and experience I’ve had with Hurricane [later Tropical Storm] Irene. I live in southwest Connecticut in a city slightly less than 100,000 population.  We are about 50-65 miles from New York City. As of this evening, I am still running my generator five days after being hit by Tropical Storm Irene on Saturday evening.  As of this evening, the power company said they will restore power “by middle of next week”.  If that ends up happening, we will be without power for around 10 days.  We shall see.  A few details …


Six Letters Re: Hurricane Irene Lessons Learned

Dear Mr. Rawles: We’ve been without power for 3-1/2 days and Internet even longer, so I’m late in writing, but I wanted to say that the grace of God and deep preps won the day, here as hurricane Irene blew through. When the power went out, we went to our generator, so we had water for ourselves and less prepared neighbors.  Those votive lights, the ones in the tall glass containers that often have saints’ picture on them were perfect for our windowless bathrooms, and they’re fairly cheap.  They burned safely almost the whole time and there’s still a day …


Letter Re: My Home Energy Backup System

James, The advice given by J.M. from Oklahoma regarding computer UPS systems could be dangerous if followed as cavalierly he/she laid out for charging and using batteries! UPS systems come in several flavors as it relates to how the batteries are used and charged. Using the wrong type or capacity of battery in a UPS system can lead to overcharging either through length of charge or how much power is sent during the charge cycle. This can cause batteries to swell, leak and explode! J.M. is correct that UPS systems are often disposed of because the batteries have gone dead …


Five Letters Re: My Home Energy Backup System

Sir: As a solar power contractor/installer, I can tell you that David L.’s power plan is a solid one. One thing he left out was the 30% Federal Tax Credit (not just a deduction) offered against the cost of residential renewable energy systems, including of course solar. A synopsis of the Federal tax credit as well as all available state credits (some huge) is online at the Database of State Renewables & Efficiency (DSIRE). Also, Eco Business Links keeps an updated listing of the lowest available prices on solar panels, inverters, and both on and off grid systems.  230 Watt panels like David used …


Four Letters Re: Hurricane Irene Lessons Learned

Mr. Rawles, I am in northwest N.J. I wasn’t affected as badly by the hurricane as others were, but I did learn a few lessons about my preparedness. 1. Inspect your gear on a regular basis. I live on a dead-end street, and the road goes over a country stream, which flows underneath through a 2-foot culvert with a paved berm built over the top of it. Yesterday, that country stream became a 40-foot wide river about 10 inches deep and flowing rapidly over the road surface. To get across that, I got out my waders — and discovered that …
