Two Letters Re: Protection from EMP Effects for Photovoltaic Panels and Communication Gear

Jim, I’m not very certain Solar Panels or photovoltaic (PV) Modules if you prefer) are up to surviving electromagnetic pulse (EMP). Solar Panel manufacture is akin to basically creating large scale photosensitive semiconductors and few manufacturers will quote even static electricity resistance, much less EMP resistance. Additionally, most PV modules have bypass diodes to protect cells. Some designs put these diodes in the junction boxes, while others incorporate them more integrally in the PV assembly. Obviously the controllers are at great risk, but the modules themselves are not free from risk. About the only references to PV and EMP you …


Wood, the Alternative Energy for the Rest of Us, by Bill S.

Solar and wind electric generation systems are affordable and efficient, but there are a many areas of the U.S. where wind systems are not feasible, and few localized areas where solar systems are not feasible. A diesel powered generator with a large underground tank is reliable, but under adverse conditions the tank could run dry. Fortunately there are two systems capable of generating electric power with wood, a fuel readily available in most parts of the country. Gasification is a process of burning wood or other solid biomass in a specialized combustion vessel (basically an upside-down wood stove) that generates …


Letter Re: Questions on EMP Protection

Hello Jim, I recently finished reading [the recently-released novel] One Second After [by William R. Forstchen].The potential realities of this story can grab you. [In the novel] a young girl who dies because her insulin supply deteriorated. Lack of adequate refrigeration degraded the quality and effectiveness of the insulin. I was reviewing some bug out literature and ran across a list of equipment that included a portable 12 VDC cooler unit. This would be great for transporting heat sensitive pharmaceuticals during a move of some distance. My question is this: What effect would an electromagnetic pulse (EMP) attack have on …


Letter Re: Sale on Inexpensive Solar Rechargeable Lights

Dear Mr. Rawles, This sale ends Saturday so maybe it’s too late to share it, but True Value Hardware stores around the country are selling boxes of six (6) solar powered pathway lights for $11.99. These would be great to use for an extended power outages – just bring them in inside each night without the pole. There’s two LED lights in each one, and they will shine for 8 hours. I tried them out last night and was able to read with two of them. Using all six lights in the box lit up my small house enough to …


Letter: Re: Long Term Health Care Needs in TEOTWAWKI

Good Morning, You may have addressed this previously, but I could use your help on this issue. Our six year old daughter has significant medical needs (none requiring electricity thankfully) requiring us to shelter in place. We live outside a major metro area and probably wouldn’t want to be on the roads anyway. Any comments for those of us who fit this bill? Thanks – Jeremy JWR Replies: Yes, this has been addressed. See this letter in the archives, from 2007. OBTW, be sure to follow the back-links there for the previous SurvivalBlog article on mid-size photovoltaic systems for medical …


Letter Re: Home and Ranch Methane Gas Generators

Jim: I saw the following post concerning Gober (“dung”) gas, dated 27 April, 2009, over at Michael Yon’s web site:. “During breaks from tracking training – I was sweating like crazy in the jungle heat – I asked many questions about Afghanistan and Nepal, and he talked about a simple way to make many of the Afghans lives easier. Most Afghans don’t even have electricity. When he was about fifteen years-old, his dad installed a “Gobar Gas” (methane) generator next to the house in Nepal. The generator is simple: the owner just collects human and animal waste, and through a …


Letter Re: Bike Frame-Mounted DC Power Generators

James, Just a follow-up to the question about bicycle power: If you do a Google search on the phrase “bicycle power generator” then several interesting options come up. One is a web site that offers free plans. JWR Replies: Just keep in mind that every hour spent trudging away on a bike frame generator is an hour that you could also use doing something else productive. Dollar for dollar and hour for hour, photovoltaic panels are the way to go–they make power every day with minimal maintenance. I consider bike-frame mounted generators fairly specialized devices for peculiar circumstances, such as …


Letter Re: Learning the Details of Self-Sufficiency

Jim, I’d like to add an additional perspective on the letter on “Learning the Details of Self-Sufficiency” — the conscious competence learning model. I’d like to pull back the shade a bit on why ‘just buying stuff’ and reading books isn’t going to cut it when the balloon goes up. Many folks are ‘buying things’, reading books, searching the internet with the thought that when the time comes, they will begin living the self-sufficient lifestyle in the country. The aforementioned letter points out the folly of this approach. I just want to take a step back and look at why …


Two Letters Re: Pedal Power for Electricity Generation and Water Pumping

James: As for using a bicycle as a PTO device, imagine being asked to pedal uphill for hours on end, going nowhere, summer or winter, until the power comes back, this is the slavery of powering off of your bicycle, it works to provide some feeble current, but there are much better ways to spend your man hours and food calories. Notable exceptions are using a small wheel generator for bike lights or small battery charging like mobile phones as you travel, BTW you will need to add a rectifier and voltage regulator circuit since bike generators produce AC power, …


Letter Re: Pedal Power for Electricity Generation and Water Pumping

Hi Mr. Rawles: Thank you so much for your efforts on this blog as well as Rawles Gets You Ready. I have a question that I haven’t seen addressed. Are there products out there based on pedal power? Meaning, I can’t afford a real alternative energy system or a large storage area for gasoline. What I’d like is a way to keep a few deep cycle batteries charged to power my rechargeable AA-size batteries (do they make rechargeable batteries in any other size?), my cordless power tools and other objects. There must be alternator/bicycle systems to do that but I …


Letter Re: The Importance of Spare Parts and Maintenance for Preparedness

James Wesley: One subject that I think is under rated in preparedness discussions is spare parts. We all are focused on our armaments and basic survival materials to the detriment of being able to continue to use our tools and equipment when they inevitably break. Even in the best-case scenario of a sever depression spare parts will be often unavailable through normal channels. A good example of this is to be found in cars. When I was young in the ‘50s and early ‘60s there was an abundance of cars made in the late ‘20s and ‘30s in remarkably good …


Is it Enough?, by Axman

I remember the Great Gas Crises of the 1950s. I filled several metal five-gallon cans with gas and put them behind the seat of my 1941 Plymouth 6-cylinder Business Coupe. I got 21 miles per gallon with that peppy little car! When Kennedy’s Cuban Missile Crises came about I dug a foxhole in my Mother’s back yard — which she later filled in and used as a flower bed. Then the Cold War with Russia, where we rattled ballistic missiles at each other. I actually built an above-ground fallout shelter out of a retired metal dumpster and a piece of …


Letter Re: A Carrington Event Space Storm–A Natural EMP Equivalent

Jim- New Scientist magazine article recently published an important article titled “Space storm alert: 90 seconds from catastrophe.” The article outlines possible scenarios for the risk of solar storms that could severely damage national grids and vital electrical and electronic systems. The effects would be catastrophic and devolve societies into a desperate survival situation for individuals. One quote from the article: “Over the last few decades, western civilisations have busily sown the seeds of their own destruction. Our modern way of life, with its reliance on technology, has unwittingly exposed us to an extraordinary danger: plasma balls spewed from the …


The 19th Century Home Retrofit, by Y. Cornelius

By now most SurvivalBlog readers have gone about your preparations for your ideal home or retreat cabin, all storage food and tools acquired, fuel stored, generators ready, PV panels carefully concealed and hooked up to the battery bank. You and your family or group are ready to handle the coming collapse, but are you really? Are you ready to do without? Without that generator when the fuel runs out, or a critical piece is worn out and a new one cannot be had? At some point your supplies will be used up, storage fuel consumed and there may not be …


Life’s Lessons and the Foundations of Preparedness, by A.B.

We may soon depend on all of what we have learned over the years. Putting all of the threads of knowledge together into a tapestry of self-sufficiency, and survival capabilities, is part of the lifelong quest for our family’s security. We learn from many sources and experiences such as: family, church, friends, teachers, teammates, co-workers, reading books and SurvivalBlog, and hopefully from our mistakes. Preparedness Skills from our Grandmas and Grandpas The foundation for preparedness begins with my childhood in Michigan. We lived in Lansing where my great-grandmother was next door and my grandmother lived next door to her. My …
