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 …

Hello, I’m new here and am starting to prepare for long-term survival. I have tons of questions but will ask only one. Do you know, or have any recommendations, how one might use battery power to, say, power as DVD player. If so, what are the best batteries to buy for long-term storage and use? I realize a small power generator could be used, but that also makes noise and uses gas. Thanks for any help. – Andy JWR Replies: There are two distinct approaches to alternative power systems. The first is the simplest, most efficient, and most cost effective: …

James: I see that Northern Tool is a SurvivalBlog sponsor. A particular item you might want to recommend is this: It is a 5-watt folding solar panel for only $39. I have several, I think they’re incredibly good for a BOB or other uses. They’re about the size of a paperback book, even lighter, and produce enough power to charge batteries fairly quickly. It’s an incredible deal for anyone who is concerned about losing power. My family keeps one or two in each of our BOBs. Highly recommended! – Bill JWR Replies: That is a great item. But so that …

Jim, You recently endorsed reader recommendations for kerosene lamps.  What about flashlights and battery powered lamps?  Do you have any recommendations there?   I realize battery powered devices may have limited value in a long-term, grid-down scenario.  But what about short-term scenarios like a power outage associated with a hurricane–a few days or weeks? Best Regards, – d’Heat JWR Replies: The advent of white light emitting diodes (LEDs) in the 1990s revolutionized flashlight technology. Up until a couple of years ago, I would not have recommended buying an electric camping lantern, since they were such battery hogs. But now, a …

There have been a number of comments on SurvivalBlog about rechargeable batteries. The majority of these expressed the feeling that rechargeable batteries were expensive and ineffective for a long term storage plan. Before anyone gives up on rechargeable batteries I would like to share a plan that has proven effective for my family. One day I sat down and assessed my family’s state of preparedness. Like many others, we needed more beans, bullets and band-aids. Turns out, we also needed more batteries. Before I started buying batteries, I tried to think of creative ways to minimize the number of batteries …

Mr. Rawles: I bought a cheapy Chinese plastic model (“Dynamo and Solar Radio” model, in a small black rectangular plastic case), and it worked okay for a couple weeks. Then the flimsy plastic crank handle broke inside the unit. At least the solar cells seem to recharge it okay if left in the sun for a few hours. The Eton/Grundig ones seem to be well constructed I hear, but now perhaps a better one is coming with a Sony model being released in Japan. They are usually pretty good about testing ergonomics and durability much more than most companies.

James: With all the discussion lately about well pumps, and alternative ways to power them, and all the expense and complications, I just have to shake my head in wonder. There is a better way, but don’t tell anybody, it is a big secret. See: http://www.theferipump.com/ and http://www.cisolar.com/CatWindPump.htm. Regards, – Doc at www.bigsecrets.cc
