Using a Dankoff Solar Powered Water Pump – Part 4, by Tunnel Rabbit

(Continued from Part 3.) Delivery Line Pressure Specifications Water pressure per foot of head, in the Dankoff chart indicates 60 PSI static pressure at 140 feet.  When water is pumped, if my gauge is accurate, 60 PSI was reached at about 100 feet. Note that 60psi is the maximum pressure rating of most 1/2″ drip irrigation that is the least expensive black poly pipe. As a quick reference when designing a system, download the PDF of this chart.  To save money, you can use inexpensive black poly pipe rated for 100 or 160 PSI for lifts above 120 feet. To …


Using a Dankoff Solar Powered Water Pump – Part 3, by Tunnel Rabbit

(Continued from Part 2.) If a 100-watt panel is used, the voltage could be 17.5 to 19 volts at its peak amperage, which is too high for long-term operation. As tested, I use two 100-watt panels, that have one cell covered with duct tape to reduce the voltage at the pump. Voltage is confirmed using a multimeter, and output measured with a one-gallon container, and a tachometer confirms that the pump head is turning at less than 1,725 rpm. Output should be slightly less 2.50 gallons per minute (GPM) if the Dankoff Model #1303 is used, and slightly less than …


Using a Dankoff Solar Powered Water Pump – Part 2, by Tunnel Rabbit

(Continued from Part 1.) There are clear advantages with the addition of electronics, and a battery-based pump system.  However reliable they may, or may not be, both of these options can fail at a future date.  As it is, if there are not the microchips to produce it today, so I would not expect it to be available during or after TEOTWAWKI. If we know how to work around a complex device normally used to run solar pumps, then we can also avoid the expense of either the pump controller or perhaps even a PV system altogether. Simplicity is better …


Using a Dankoff Solar Powered Water Pump – Part 1, by Tunnel Rabbit

The Mission: To “Survive and Thrive” In my opinion, the ability to irrigate crops is not covered adequately.  Few have a plan, or the ability pump water for decades without electricity from the grid.  And fewer still have a contingency plan that includes relocating with this critical ability. Not only is our currency at risk, at the same time, so is our food supply and the ability to grow it.  Famine could soon be in the land. What is occurring in the world today has no equal in modern history books, but has been foretold in the Book of Revelation. …


Backup Power Generation Considerations, by Tractorguy

Emergency backup power is a key consideration in prepping for emergency situations and disasters. This is not meant to be a exhaustive discussion of different types of generators and backup power systems, but rather a discussion about critical items in an emergency situation. Backup power is a two-edged sword. Many people think they are ready for a power outage because they own a generator, with no consideration given to proper connection, maintenance, fuel availability, or operation. I have been maintaining generators and backup power systems for more than forty years as a broadcast engineer and engineering consultant, and I can …


An Electric Car for TEOTWAWKI? – Part 1, by S.B.

I’ve been working on an article for SurvivalBlog on electric cars for quite some time…writing a little bit here and there then prioritizing other activities and halting work. With the recent Colonial Pipeline ransomware fiasco and associated fuel shortages on the east coast Report: U.S. Capital Nearly Out of Gas While NC, VA Also Endure Outages (breitbart.com), I thought this an opportune time to buckle down and finish up the article. Regardless of how you interpret U.S. Energy Secretary Jennifer Granholm’s recent statement regarding the Colonial Pipeline shutdown where she said “if you drive an electric car, this would not …


Simple Photovoltaic Power, by A. DoItYourselfer

This article presents my photovoltaic power experiences to give fellow do-it-yourselfers an understanding of what it takes to use the sun for energy. I am a 69-year-old carpenter with experience in residential, commercial and industrial construction. I abhor relying on others for needs. So that is what drove me in the area of energy, especially stored energy. By “stored energy, I mean propane, solar battery systems, stored food, and so forth. I live in Arkansas which is considered a subtropical climate in late spring to early fall. The heat in summer coupled with humidity from the Gulf of Mexico is …


Lessons Learned from the Texas Deep Freeze, by B.B.

Texans had two weeks warning about the artic cold set to hit the state last month. Yet most Texans were not prepared. It is estimated that 80 people died from the cold and lack of power. Some froze to death from lack of heat while others died from carbon monoxide poisoning trying to stay warm in foolish ways. It started Sunday night with rolling blackouts in my area, but complete power outages in some areas. For my family, rolling blackouts continued through Wednesday night, ending in the early hours of Thursday morning. During this time, many lost water service, either …


Letter Re: 2021 Winter Storm Lessons Learned

Dear Editor: Regarding the 2021 Winter Storm Lessons Learned article, I have a few recommendations: I keep a 1800W variable speed inverter generator around to charge phones, run the internet and routers, power a computer, run a television and keep the refrigerator or freezer going.  It is quiet, doesn’t disturb the neighbors, and sips gasoline, especially with the variable speed.  It is small and light enough I can bring it into the house to keep it warmer for easier starting. For the car and the generator I keep a can of ether in the shed.  Most cars today do a …


2021 Winter Storm Lessons Learned , by Chill N. Texas

I am a long time reader of SurvivalBlog.com but this is my first time submitting an article to the blog. Much of this will be “train of thought” as I am reading through my notes that I was keeping during and immediately after the exceptionally cold winter storm that hit the Houston, Texas area in February, 2021. I have been “preparedness-minded” most of my life, but didn’t consider myself officially a “prepper” until about 10 years ago. I have generally had the support (or at least she humors me) of the wife when it comes to being prepared, but as …


JWR’s Recommendations of the Week:

Here are JWR’s Recommendations of the Week for various media and tools of interest to SurvivalBlog readers. The focus is usually on emergency communications gear, bug out bag gear, books, and movies–often with a tie-in to disaster preparedness, and links to “how-to” self-sufficiency videos. There is also an emphasis on links to sources for storage food and a variety of storage and caching containers. You will also note an emphasis on history books and historical movies.

Low-Tech Off-Grid Living, by Ani

80

I’m writing this article early in the morning during a power failure. I’ve only lived in this house for six months but this is not the first power failure I’ve experienced here. Previously I house-sat in this town and experienced a long duration power failure complete with four days or so of no cell service either. I got on my phone and looked up the outage map and realized that my town and a couple of adjacent towns have a significant outage, definitely due to the high winds of last night. The electric utility will begin mobilizing the line crews …


PV Solar Panels Can Pay For Themselves, by St. Funogas

71

Author’s Introductory Note: Grid-tied solar panel payback time is less than seven years in most of the lower 48 states, and quickest in some of the New England states, so don’t think solar isn’t for you just because you live in North Dakota or Vermont. RUN THE NUMBERS which I’ll show you how to easily do. If you don’t care about all the details of how and why, skip to the last section called “Quick Way to Figure out Payback Time.” There are only three numbers to enter on your calculator and you’ll have your payback time in years. Then …

An Old Boy Scout’s Journey – Part 2, by Rocket J. Squirrel

17

(Continued from Part 1.) There is a DeWalt 6 kW generator with a Honda gasoline engine that was purchased used. The local Stihl dealer gave it a tune up. Spare spark plugs are kept in the tool box. I have very limited gasoline storage but do have a tri-fuel kit. The tri-fuel kit from www.uscarb.com enables the generator to use gasoline, propane, or natural gas for fuel. Make certain you buy the kit which matches your specific engine model. I need to get the kit installed as well as the natural gas fittings for our current home. Natural gas may …
