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 …

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. …

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 …

Letter Re: Generators And Their Proper Implementation During TEOTWAWKI/Disasters

HJL, I’ve passed this along many times to JWR when the subject of generators and transfer switches come up. It is a more versatile solution than a transfer switch. It is a product named Generlink. It installs at your pole and allows you to choose which circuits to power via your breaker box, instead of having to wire specific circuits with a transfer switch and is a less expensive solution than a transfer switch. Generlink has been approved by my electric co-op and many others. Check it out at generlink.com, I have no financial interest in it. Regards, Keith o …


Letter Re: Generators And Their Proper Implementation During TEOTWAWKI/Disasters

Excellent article about generator usage. I might mention that when using a portable generator there is a better option than running an extension cord to an outlet and then cutting off the main breaker. You can buy a manual transfer switch that will allow you to wire selected circuits in your breaker panel through the transfer switch. After plugging up and starting the generator, you flip breakers on the transfer switch. This transfers the selected circuits to the generator output and isolates them from the main incoming power. These switches are readily available at almost any home improvement store or …


Generators And Their Proper Implementation During TEOTWAWKI/Disasters, by RKM

I want to share useful generator information so that serious and possibly dangerous pitfalls can be avoided and tactical efficiencies can be realized. Outside Only: First, there is an important warning– generators MUST be run and exhausted OUTSIDE! Carbon monoxide can and will kill you with no warning. Carbon monoxide has no smell or taste. Of course there are things you can do to run one inside, but that involves technical issues not covered here. Be careful and plan accordingly! Our emergency implementation: On August 23rd of 2005, Hurricane Katrina struck Southeastern Louisiana and Mississippi. Fortunately, I was living in …
