Chainsaws and Long Term Gasoline Storage
After reading Edventures' letter about there not being any diesel chainsaws available, I had a thought: why not combine an electric chain saw with a small, portable, diesel generator? Besides solving his fuel problem, he would also have a mobile power source that could be used to operate other devises.
Military Strobe Light Batteries
Regarding's Dave's recent mention of the Firefly strobe: "...the PX32 can also be used in an adapter for the old "Firefly" strobe..." I just thought that I'd mention the solution I found for military strobe batteries.
Battery Options for LEDs and Small Electronics
Regarding LED flashlight batteries: I have a flashlight from Sportsman's Guide that uses two of the CR123 batteries, it will also use the #18650 lithium ion battery. One of these takes the place of two of the CR123 batteries, and last much longer, and is rechargeable.

DC to DC Converters
Some of our TEOTWAWKI preparations tend to lean toward running electronic equipment off charged DC battery sources. I work in electronics, and have built several radio stations for ministries around the world, I have found that DC to AC inverters especially the cheaper models are very inefficient to run higher powered equipment.

The Importance of Testing "Dead" Batteries Before Recycling Them
I wanted to share a money saving tip that applies to inexpensively preparing for TEOTWAWKI. With so many digital devices depending on batteries these days, most of us are conditioned so that, when a device like a digital camera or other smart gadget tells us the AA or AAA batteries need replacing, we simply toss out the “dead” ones and put in fresh batteries. But are the batteries really dead? Usually, not all of them are.
Off Grid Alternatives to Utility-Supplied Electricity
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.
Buying Kindle Reader for Accessing Survival References?
Buying a shiny new Kindle for that purpose is like "putting all your eggs in one basket". I would much rather put all my archived preparedness reference documents on multiple copies on CD-ROMs and then buy two or three used laptop computers with cosmetic defects.
Advice on an Inexpensive Solar Battery Charger?
In your comments to the family living in Trinidad & Tobago, you wrote: "As your budget allows, buy a small solar charger for your AA and AAA NiMH batteries."
Do you have personal experience with any of these solar chargers? Can you recommend any?
Generators Build a High Power AC/DC System
Build a High Power AC/DC System. This DIY systems can offer different values than off the shelf products. Like turning a 12 volt alternator for additional power and building a system for you specific needs.
AA Cells and Mobile Power
There was a discussion about batteries a few days back on SurvivalBlog. The writer advocated using AA NiMH cells almost exclusively, with adapters for devices requiring C and D cells. While I do agree that this is a good approach for some devices...

Converting a Motor to run on Propane
Converting a Motor to run on Propane. This can be used to run a vehicle or Generator. Very Practical. Engine conversions must be carried out by qualified technicians and/or persons who will follow all safety guidelines as contained in pamphlets NFPA 54, 58, 38 or any other publication or guidelines stipulated by local, state or federal agencies and the authority having jurisdiction.

Phone Line Power for Emergencies
I found this web page interesting: Free Hidden Electricity.
Essentially this site has provided some basic information on how to tap the small amount of electricity available in our land lines to use for charging batteries or powering a lamp should the power go out (and not the phones) in a small emergency scenario.
Here is an article describing the challenges associated with betavoltaic batteries. The recent buzz over the 30 year battery, while intriguing, is overly optimistic.

The Importance of Stocking Up on Batteries
It is that one of the crucial logistics for modern armies is spare batteries. He described how they go through hundreds of them, for radios, tactical flashlights, sensors, laser target illuminators and designators, and night vision gear/thermal sights. As I look forward to potential hard times in this country, I think that we should learn a lesson from the Iraq experience: never run out of batteries.
