One Log DIY Rocket Stove
One of the most common questions that I am asked from non-prepper friends and acquaintances is what exactly is a rocket stove and how do I get one. I try not to roll my eyes over this because although rocket stoves are common among campers, backpacking enthusiasts and former boy scouts, they are a relative unknown to city dwellers and individuals that do not spend a lot of time outdoors.
According to Wikipedia, a rocket stove is an efficient cooking stove using small diameter wood fuel which is burned in a simple high-temperature combustion chamber containing an insulated vertical chimney that ensures complete combustion prior to the flames reaching the cooking surface. Seems simple enough, especially when you consider that rocket stoves are found more commonly in third world countries where wood fuel sources are scarce so an efficient system for converting twigs, branches, pinecones, leaves and other bits of biomass to fuel is essential to cooking.
There are a number of commercial versions available and indeed, I own both the Solo Stove and the EcoZoom Versa. On the other hand, if you are a bit handy with some basic tools, you can build your own for as little as a dollar or too. All it takes is a bit on interest and a bit of work. Last month I connected with Ken Youngquist at SurvivalTek regarding a unique rocket stove that he built from a log her found on his property. The advantage of this particular rocket stove was that it was elevated, making it easy on the back while feeding fire or cooking. Not only that, it kept you off of the damp ground, which, depending on where you live, is a big plus. I was fascinated by the one log rocket stove and shared it over on Facebook where it received a ton of comments. Today, on Survival Friday, I share it with you.
The One Log Rocket Stove
Years ago I wrote about how to make “The Swedish Log Candle” and have since noticed many variations of the same theme appear throughout the internet. While log candles can be used for cooking, rocket stoves in general have been a popular topic as well. There are now a number of various rocket stoves that are made out of a single log, similar in effect to a log candle. After viewing several videos on one log rocket stoves I decided to try it out for myself. Although I believe pine would be a preferred wood, I used a seasoned poplar log that I had available. I recommend using a corded high-torque drill for this process. I set the 14″ log upright and used a 1 1/2″ blade bit to drill a 6″ deep hole down the center from the top. Then I laid the log on it’s side and drilled a second hole, intersecting the first hole at it’s bottom end.
Just a note: at the point of intersection, a blade bit can give a hellacious “kick” so be careful as you approach that point. After blowing out the saw dust I set the log upright to begin preparing it for fire.
As long as I took the liberty of using an electric drill to make a natural material rocket stove, I also took the liberty of using a manufactured tinder by using bamboo skewers. Purists can figure a way to approach this project more naturally but I figured “who cares? This is fun!” I collected a bundle that was about a third of the volume of the hole and poured gasoline on it and the hole walls before inserting them down the shaft. It’s important to “wet” vs. “flood” so as not to have the fluid stream out the bottom hole. Use caution when lighting it with a match or lighter. In this case gasoline was handy but other accelerants would work as well.
Conventional rocket stoves have larger diameter holes and thus fuel can be fed from the bottom hole. When I tried this approach it seemed to choke out the airway and snuff out the existing flame, so I recommend feeding any kindling from the top during the initial process of establishing the stove’s fire. Once the flame was established I selected three 1″ high stones that I placed around the top surface of the log which became the tripod or trivet for my pot and pan. I initially brought a pot of water to boil for coffee, then continued with a pan with which to fry bacon and eggs. Although this rocket stove takes some “manufacturing” to make, it is a great project for a number of reasons. These can be made ahead of time and stored for power outages, camping trips and garden gatherings. Outside of a little tinder and some accelerant, they are self contained and don’t require the gathering and consumption of local natural materials. They can be controlled and extinguished by using a spray bottle of water and thus can be used multiple times. Because it is elevated, it can also be used in a wet environment. Furthermore, they last for hours and are a joy to use.
About Ken Youngquist: SurvivalTek is the creation of Ken Youngquist, a guy who from his youth was captivated by primitive living skills, and in his adulthood, was intrigued by the television Series MacGyver. The result has been the study and practice of survival skills, and the desire to pass on the mantle of preparedness to others. SurvivalTek contains almost 6 years of weekly articles that support subjects of interest to those of us wanting to learn more about survival and preparedness techniques.
The Final Word
Having the ability to cook outdoors is so important that I tend to write about the various options frequently. This is definitely an area where one size does not fit all. Whether you prefer to build one yourself using Ken’s method, build one using the method described in Building a DIY Rocket Stove or purchase one outright, there are a number of options available to insure that you will be able to cook when the grid is down. And just when you think you are all set, don’t forget to practice using your rocket stove! As with all survival skills, practice makes perfect. Learning how to build a fire in your rocket stove and how to cook with it is an all-important task that should be done 3 or 4 times a year, just for practice sake. The bonus is that you might actually have a bit of fun in the process. And who can argue with that? Enjoy your next adventure through common sense and thoughtful preparation! Gaye.
