Making Light, by M.E.

Artificial light is useful for extending working time beyond sunset, for providing comfort in the long dark hours of winter, and for finding one’s way in the night. Without electricity or batteries, solar cells or wind up flashlights, lamps and candles can be made just as they have been for thousands of years. The cave paintings of the Upper Paleolithic were done by the light of lamps that used a lump of animal fat as fuel and lichen, moss, or juniper twigs as wicks. The light of these crude lamps was sufficient to produce some of the earliest known works …


Generators for Family Readiness – Part 2, by Greg X.

(Continued from Part 1. This concludes the article.) Starting Electric starting is a nice feature. An electric starter motor spins the engine faster than pull starting increasing the probability that the engine starts. The starter keeps the engine spinning longer because a starter rope always runs out of length. My wife can push the start button and if your back is hurt “the button” still works. Gasoline engines are easier to pull-start than diesels. There are some small diesel engines with compression release that can be pull started, but it can be tough even for a 3-kW engine. We put …


Generators for Family Readiness – Part 1, by Greg X.

Many of us own a generator. But how much research did you do before purchasing yours? Generator system integration into you home power design is frequently a series of tradeoffs. I’m going to cover how generators work, potential design features, trade-offs, and strategic considerations. I actually own four generators of various capacities, fuel types, and features, each for slightly different purposes. I also work doing generator fleet maintenance. Key Components I like to break generators down into an alternator, and engine, a DC control system, an AC control system, a fuel system and a cooling system. Generator sets are typically …


Our Winter Indoor Greenhouse Room, by Avalanche Lily

I was recently asked for any advice that I could give concerning growing foods indoors. Growing anything indoors or outdoors is always an experiment, because there are so many variables to contend with.  In essence: Indoors: humidity, light, and nutrition. Outside: sunspots (or lack thereof), temperature, cloud cover, rain, drought, storms, bugs, soil nutrition, et cetera. Let me preface that I have no claim at all in thinking that I’m an expert. I’m not. I am no expert at all, nor am I an expert in any subject. I am a “by the seat of your pants” kinda girl.  I …


What I Learned From the Recent Power Outage – Part 2, by A.K.

(Continued from Part 1. This concludes the article.) The house is located in a rural locale with only two other homes on the road (friends of theirs). They have a well and septic system. And they even have a decent amount of food stored such as canned goods that I could access in an emergency(and pay them back for later). I was pretty pleased to realize this. I actually felt the best here (and safest) that I have felt during my entire time traveling. I figured that in an emergency I’d be okay here for a while. It’s even located …


Elements of a Security System – Part 5, by J.M.

Observation As I mentioned earlier, direct observation of an intruder approaching is another form of detection, but I’m focusing on situations where you may not be able to have eyes everywhere 24×7. However, if an alarm does go off you’ll need some way to get ‘eyes on’ to determine what caused the alarm without unnecessarily exposing yourself to potential danger. There are a number of possible options to enhance your ability to observe a potential intruder. The simplest and most obvious option would be magnified optics, such as binoculars or a monocular, assuming you have a line-of-sight to the area …


Letter: Converting Edison Lamps to 12 VDC

Jim, Would you mind offering a link for a 12-volt bayonet mount adapter [for standard 120 Volt AC floor and table  lamps to use automotive interior and tail lights] that you referenced in your novel Patriots? Thanks, – Marc JWR Replies: Marc: Sadly, those bulb adapters are no longer cataloged by Real Goods. These days, with the profusion of inexpensive LEDs on the market, I would instead opt for Edison base 12 VDC LED conversions. This makes sense because LEDs draw so much less current than traditional automotive filament bulbs, and they have a much longer service life. NOTE: These …


Preparedness Lessons from the 1930s – Part 1, by J. E.

It’s one or two years after an EMP attack and you are safely tucked away in your retreat somewhere in the middle of nowhere. Your storage foods have mostly been used and your high tech electronics is useless. The really bad stuff is mostly past. Now it’s try to stay fed and alive and pray that civilization as you know it is coming back. You’re going to have to work your environment to live. Ever wonder what life might be like to Homestead? What would it really be like to have no running water, electricity, sewer, newspaper or Internet? No …


Bell & Howell TacLight Lantern/Flashlight Combo, by Pat Cascio

When the lights go out, we usually reach for a flashlight. However, there are much better forms of portable light. Today we check out the TacLight lantern and flashlight. They are winners. I’ve owned many LED lanterns over the years, some were really bad, and some were a bit more than okay, when it came to giving us light, when the lights went out. Living in the boonies, we lose electricity quite often from trees falling on power lines because of heavy snow, rain, and winds. It just comes with living out in the country, and we are usually the …


Family Earthquake Preparedness: Are You Ready?

The recent strong earthquake near Anchorage, Alaska underscores the importance of family earthquake readiness. Thankfully, we live in a country with modern building standards. This is not in the case of many Third World nations, where unreinforced masonry construction is the norm. In the Third World, folks tend to be very stingy with reinforcing bar (“rebar”). So its seems that every time there is a large earthquake in those regions, there are building collapses, with large loss of life. By far, the safest houses for earthquakes are of wood frame construction. This is because such structures can flex and sway, …


Hurricane Preparedness Experience- Part 3, by N.K.

Cooking was interesting. I had a propane gas grill with two spare 20-lb cylinders, a dual-fuel Coleman camp stove, a couple of single-burner butane units, and the ability to build a fire in the backyard. The gas grill got used, because it was easiest. It did take a couple of days to learn how to cook more than simple camping meals on it. We have an old style coffee percolator for camping, and getting the heat to it correctly on the grill took some learning. Cooking on the grill was something we should have practiced before we needed it. A …


How to Use Old Cooking Oil: The Floating Wick

A few months ago, one of my consulting clients mentioned that she had over-stocked her supply of vegetable oil. She had also neglected to store it in her freezer, to extend its storage life. The result after four years was 10 quarts of corn oil and two quarts of olive oil that had gone rancid. She asked if there was anything she could do with the oil. (She bemoaned the fact that that olive oil was particularly expensive.) My reply: Buy some floating wicks, and burn up that oil as a source of light and heat, during power failures. Floating …


Letter Re: Emergency Lighting

Good afternoon, Hugh, Two recent experiences drive me to write– a recent overnight house guest and a link today on Instapundit about surviving disaster (http://www.bbc.com/future/story/20150128-how-to-survive-a-disaster). My house guest commented on the number of my night lights and the fact that I have a floor lamp powered by a UPS (Uninterruptible Power Supply), which is a “battery backup” typically used for computers. First, the night lights are what I prefer to call “target identification lights”. They’re not used just in the bathrooms; they are positioned to ensure anyone moving through the house must either cast a shadow or be silhouetted. This …


Scot’s Product Review: Streamlight Weapons Lights

Bad things can happen in the dark, and one of the great comforts we have is being able to make light. Light allows us to perceive our surroundings and make our way without stumbling. One thing I am seldom without is a good compact flashlight in my pocket. Over the last few years, weapon-mounted lights have become popular, especially in law enforcement circles. They are probably even more popular in Hollywood entertainment, and if you can stand the stuff, you will probably see at least one scene in almost any action TV show or movie with the hero searching about …


Letter Re: Alternate Lighting

Hugh, I’d like to tell you about a product I recently bought at Costco the other day. I have no stake in the company. It’s from Sunforce; it’s a 80 LED solar motion light. It has 900 lumens output from 80 white LEDs. It has a separate solar panel that’s connected by a 15 foot cord to a battery pack in the light fixture. It has a motion detector and a three position switch: on, off, auto. I charged the batteries for three days, per the instructions for the initial charge. I put the switch in “on” position, and it …
