A Project to Produce and Store Heat, Energy, Water, and Food, by T.S.

We all know that we can’t survive very long without water, food, and heat. Because we live in uncertain times, the benefits gained by this project would more than offset the initial cost. In a grid down situation, the extra heat, stored water, energy, and food production would be invaluable. The list of benefits include but are not limited to: Heat production to help heat the house. Water storage plus heat storage. Solar energy production and storage. Food production. Three years ago on a sunny winter day, I went out on our south (well, more like a southwest facing) porch, …


A Beginners Guide to Practical Prepping: Lessons From a True Story of Disaster, by R.L.

It was September 1989, a time in history that is forever burned into my memory. I was working as a firefighter in a small town outside Columbia, South Carolina. Hurricane Hugo had developed in the Atlantic, it was ripping apart the Carribean islands and it was headed our way. All the news on television and radio were inundated with updates on this killer storm; we were tuned into the Weather Channel at the firehouse carefully watching and waiting. The original forecast was that the Category 4 hurricane would turn north and only threaten the North Carolina coast. It was assumed …


Scot’s Product Review: SGK 440 Portable Power Solar Go Kit

This is something I wish I had owned back in my old days at the newspaper. We sometimes had to go places where there was no electricity and coming up with power could be a real hassle. As the years rolled by, the need for power got bigger and bigger. When I started, the cameras were mechanical and we shot film. By the end, everything was digital and required batteries, plus we had computers and cell phones too. We often drove around blowing fuses in cars with inverters plugged into the lighter socket in a desperate effort to keep stuff …


Guest Post: Living On The Edge When The Grid Fails, by A.M.

Using Waldon Pond as a guide and an early Banner motor home as an inspiration, 22+ years ago I wired my 2,000 square foot home for 12-volt and 110-volt solar emergency lighting and light work. Pictured is the home-built control center for the three panel system, which is 100 watts. The 300 watt wind turbine can be used for pumping water when hooked to the single battery or it may be used to charge a neighbor’s battery for barter. A short-run gas generator (110 volt 22 amp) handles the heavy loads when the grid is down and is disconnected from …


Scot’s Product Review: Quantum Harvest Model 120

This review is part of my continued exploration of backup power during disruptive times. Life without electricity, even for a few hours, is unpleasant and could even be life threatening. I was reflecting about this during our last Scouting campout as I saw how many battery-operated devices were in evidence. It was mostly flashlights, but there were also two-way radios for communications, cell phones for emergencies, and the like. We are supposed to leave entertainment gadgets behind, but I admit to having a book reader on most trips, and I keep copies of first aid guides and similar materials on …


The Power of Steam – Part 4, by A.Y.

For problems on the engine itself, visual inspections are again the best way to look for problems. Loose bolts, loose or worn bearings, signs of overheating, and clanking and knocking sounds can attest to problems. Signs of overheated metal on the engine can include scarring, discoloration, scraping sounds, and emitting lots of heat from a bearing while in operation. Overheating on the engine itself can usually be attributed to not enough lubrication, so it must be determined why oil and grease are not getting to the affected part. Some engines have mechanical and hydrostatic lubricators that drive oil to moving …


The Power of Steam – Part 3, by A.Y.

Heating the Water While water management is one of the most important aspects of boiler operation, the other is being able to heat the water. Since the age of the steam engine, wood, coal, and oil have been the three main fuels used to boil the water. Each has their advantages and disadvantages, and this must be considered thoroughly for use at a retreat. In this discussion, oil will not be considered as a fuel; the reason for this is, like gasoline, it can be expensive to constantly replenish, needs large volumes of storage space, and takes refineries to process. …


The Power of Steam – Part 2, by A.Y.

Monitoring and Maintaining the Water Level Remembering the most important thing, which is Do NOT EVER let the water drop below the top of the crown sheet, there are sight glasses mounted on the backhead (rear) of the boiler to monitor the amount of water, and these must be watched constantly. Most boilers have two sight glasses; both are connected to the boiler at the top and bottom and have notches in the glass to help observe how much water is in the boiler. They also have drains on the bottom for cleaning out trash in the sight glass. These …


The Power of Steam – Part 1, by A.Y.

You have bullets, beans, band-aids, bibles, bullion, and everything else you can imagine for when the cataclysmic end of society as we know it arrives. You bug out to your retreat and have everything ready to weather the storm of looters, power hungry officials, and no infrastructure, but have you considered an alternative way to pump water? What about an alternative way to power electric generators? An alternative way to power machinery? An alternative way to move heavy equipment place to place? A way to help rebuild your community, using some clean water and anything that will burn? I am …


Letter Re: Question on generators and EMP

HJL, We have been considering having a whole house generator installed at our house, since we occasionally lose power in our neighborhood for days at a time. Additionally, the threat of an EMP pulse damaging the grid and our being without power for a lengthy period of time is an even greater concern. My question is: is a whole house natural gas powered generator, like a Generac 22kv unit (along with the associated auto switching panel), susceptible to EMP? If so, what would be the best way to protect it? When I ask the electrical contractors bidding on the job, …


Motorizing a Country Living Grain Mill for 12-volt Battery and Solar, by I.S. – Part 1

Introduction The Country Living Grain Mill is a robust mill that will last for generations and is a fine choice for any home or retreat. It has been designed to be motorized easily, however the manufacturer’s motorization kit is expensive and operates on 115 volt AC power, thus requiring grid power, an inverter, or a generator. The following article will describe how to power your Country Living Grain Mill from 12 volt batteries or solar panels for less than $200 (excluding the power source and associated wiring). Currently, all necessary materials are readily available. Tests have shown this setup can …


Letter Re: Backup Electrical Power

Hugh, In Great article by Duliskov on backup electrical power, he suggests a propane tank heater/cover to counter low temps that reduce available propane. I noticed it’s a spendy item. Depending on your conditions, you might get by with one of these and a blanket. Speaking of low temps, just a reminder of how handy thermostatic switches are as part of a freeze-protection system. My pump house is very well insulated, but I have a 100W bulb on a thermo switch which comes on if needed. Best regards, – D.O.


Letter Re: Backup Electric Power Design Considerations

Hugh, Great article. On the connection from the box where you consolidate the power coming off the panels to the charge controller, it has been suggested to me that I use wire made for welding applications. I am told it has finer, more numerous strands of wire and therefore transfers more power, minimizing amperage loss. My source is a guy that builds high performance golf carts.. (Everything is relative.) Something called DelCity.net is where he goes. The author is right about storing gasoline produced in autumn. They put more butane in the gas for winter to help with cold weather …


Backup Electric Power Design Considerations, by Duliskov – Part 2

Energy Storage The only practical way to store electric energy is in chemical form, in batteries. There is loss of energy while it is being deposited into batteries, converted into chemical energy, and then also while the battery sits in storage (self-discharge). The output will be DC current. Batteries are built from units of two volts each. Six of these units make a 12-Volt battery, et cetera. Physically larger batteries are more susceptible to damage from rough handling (drops, vibration) because they use larger plates. Some batteries are of sealed type and require no maintenance; some are of open type …


Backup Electric Power Design Considerations, by Duliskov – Part 1

This article covers a complex area, and to keep myself focused I will break it into three sections. In the following I would like to share what I learned while researching and building an emergency power station. The content below assumes that the reader understands the basics of electricity (AC and DC), batteries, and solar power. I have no affiliation with any of the sellers of products I provided links to; the links are for your convenience only. I have no engineering degree and reserve the right to be completely wrong. However, I did build everything that I am writing …
