Propane As An Energy Source- Part 2, by JB

Storage Tanks and Transfer of Propane (continued) Once the tank is full, the fill hose ball valve is closed (stopping flow into the tank), the tank bleeder is closed (if used), the pump is shut off, and then the tank valve closed, in that order. Double check that the hose and tank valves are closed. The small unloader valve between the hose ball valve and tank is opened to drain the liquid trapped between the two, so the hose adapter can be safely disconnected from the tank. Failing to bleed the liquid trapped between the tank and ball valve can …


Propane as an Energy Source- Part 1, by JB

Propane, or liquefied petroleum gas (LPG), is an excellent energy source for several reasons. It stores easily and has a great shelf life. It’s portable and can be adapted for use in internal combustion engines. It can also be used as a refrigerant, and in some situations a viable weapon. Long after the grid goes kaput and gasoline has turned to varnish, propane will still be usable. Basics of Propane There are hundreds of thousands, if not millions, of full grill bottles stacked in exchange racks throughout the country. In addition, there’s a multitude of medium and high volume tanks …


Letter Re: Hurricane Matthew–Some Lessons Learned

JWR & HJL: That was another great article [on Hurricane Matthew]! A suggested alternative that I have adopted is buying a turbo diesel automobile and truck.  The benefits are simple and yet many people still have not discovered the option. Here are a few:My VW tdi as an example gets about 43 miles per gallon, so with a 15 gallon fuel tank it achieves about 600 miles plus on a  tank, and by adding three NATO style 5 gal metal cans (15 gallons total) in the trunk I have a 1,200 hundred mile cruising range. That is hard to beat. …


Letter Re: Hurricane Matthew–Some Lessons Learned

Good Morning, SurvivalBloggers, SurvivalBlog recently had a very good list of hurricane preparation tips in Hurricane Matthew–Some Lessons Learned, written by a Florida resident. As a former 20+ year Florida resident I’d like to add to his excellent piece. In Florida, hurricanes are a way of life, and the period from June 1 to November 30 is known as “hurricane season.” The period from December 1 to May 31 is known as “not hurricane season.”  “Not hurricane season” is when one should be doing their preparation for the other six months. During “not hurricane season” one can find plywood on …


Letter Re: Differences Between Combustible Gases

James, Hugh, Before someone gets hurt or blows themselves up, here are some more details on the gases in question. Natural gas is produced primarily from high pressure gas deposits deep within the earth, and to a lesser extent as a byproduct of oil production. Natural gas is what is provided to most homes that are connected to a gas main, served by a gas company. Natural gas is primarily Methane gas, with a formula of CH4, or one Carbon atom with four Hydrogen atoms. Methane has the disadvantage that it cannot be liquefied by compression. Natural gas must either …


Two Letters Re: Differences Between Combustible Gases

HJL, I read the article on combustible gases. You have to be very careful with the cheap conversion kits to propane for generators; almost every one of the cheap ones do not have a device to cut off the propane if the engine stops. Like loss of spark or low oil, it will keep pouring propane into the Gen set. I have been a mechanic since 1967, and these cheap kits are very dangerous. I have seen several cause explosions. – B.L. o o o Sir, I just finished reading the post about different kinds of gas and saw some …


Letter Re: Differences Between Combustible Gases

Dear Hugh, In response to D.H.’s questions on gas, I offer my thoughts. Generally, I would tell anyone to use the gas specifically recommended for the equipment they intend to use. Trying to keep it simple about the different gases, an explanation of the differences follows. The first difference between the gases is chemical makeup. Propane has three carbons atoms (and hydrogen atoms) in the molecule. Butane has four carbons, and so does its isomer iso-butane. Butane is arranged in a four carbon chain, while Iso-butane has a center carbon, with the other three carbons coming off like spokes, and …


Letter Re: Differences Between Combustible Gasses

HJL, The difference between CNG and piped-in gas to your home is simply pressure. The gas in my house is at 7 psi and if your thumb is big enough you can stop the flow. CNG could be as high as 3000 psi, and you find it in tanks for vehicles that burn natural gas and filling stations for natural gas burning vehicles. The difference between butane, propane, and natural gas is British Thermal Units (btu) generated by a cubic foot of each substance. From high school, a btu is the amount of energy it takes to raise one pound …


Letter: Resilience

HJL: When I read PrepperDoc, I order the stuff with the grand idea of implementation. Well, my first success with all that equipment was to take apart my son’s silent “Monkey George” alarm clock and solder in a new motor. I paid attention to voltage and dimensions and ordered it online. Success is defined based on: It rings (quite loudly); It does not smoke; and My eight year old son is elated. Best of all I kept a promise to my son. Lastly, my confidence level improved. I am sure I will have an EMP-proof antenna installation in no time. …


Letter Re: Backup Electric Power Design Considerations, Expat and Other Thoughts

HJL: Welding cable is a fine way to cut amperage loss in your line. However, since it is intended by the manufacturer to be used for welding and not solar system, it is labeled for welding and not labeled for building installation. Code inspectors want to see a certain label. They will not accept deviation. After all, an abundance of engineering went into what is in that code. Welding cable use would make pulling a system when bugging out much easier. (I am assuming there are a range of “bugging out” versions with regard to situational haste.) Since you cannot …


Letter Re: Observations of An Old Alaskan Bushrat

Hi Mr. Rawles, I just ran across your site and have been browsing it. Your Precepts of Survivalist Philosophy are superb. Best is that you are a 100% sold out Christian. You may find a few observations of interest, from one who has lived extensively off the grid. First, some background. I grew up in a tiny community with the surf out my front door and a thousand-year-old forest that stretched for miles in back. My father grew up on a homestead and trapline among the Sarcees of the Alberta Rocky Mountain foothills. He never had a pair of shoes …


Response to Making a Final Run, by Jim Fry

I must confess that I haven’t had a chance to read every single post on “Making a Final Run”. A farm in winter can be a very busy place. So I hope I’m not just repeating someone else. In the main I agree with most posters, a final run is possibly/probably not a good idea, maybe. If you’re talking about a last run to Walmart, then maybe you run the chance of getting into the middle of where you don’t want to be. However, there are lots of other sorts of “final runs”, such as to the bank, the gas …


Letter Re: Long-Term Gas Storage

Dear Hugh and Jim, Here is my anecdotal knowledge relating to long-term storage of gasoline. I grew up on my family’s dairy farm in northern Wisconsin. My dad had a 300-gallon steel gas tank that sat on a stand about six feet off the ground in the shade of a White Pine tree. He refilled it every year or two, and that gas powered our two Allis Chalmers WD 45 tractors and the other gas-powered engines, lawn mowers, etc., on the farm. So far as I know, he never used any stabilizers and we never had any fuel-related problems. Of …


Letter Re: Gas and Diesel Storage

Hi Hugh and Jim, I am from Southeast Asia. Thank you for this article. I have been searching for answers to this topic for awhile, but I have not came across anything helpful out there. I have consulted with reps from oil and gas companies, but none were willing to share their insights on the matter. Since long-term storage for gasoline seems slim due to its inherent problems, would long-term storage of diesel to power generators, trucks, et cetera be a better option. Would the same problems related with quick expiry (instability), requiring special containers and flammability associated with gasoline …


Letter: Long-Term Gas Storage

3

Hi Hugh and Jim. I am trying to figure out what to do regarding safe long-term gas storage. There are some that recommend treating gasoline with Pri G and sticking it in a HDPE plastic drum filled to the top. Others suggest that if you treat the gas every year with Pri G it will last “forever”, even ethanol gas. There seem to be a few common sense caveats, like cooler is better, temperature swings are bad, and you need to keep the tank full, et cetera to give themselves an out. I find this hard to believe. I have …
