Note: Not all of these stoves are wood gas stoves, but just simple screens that help focus and elevate heat and flame from wood fuel. From what I have read, the BSA was getting complaints and also observing a rise in injuries related to constructing the popular Pepsi-can alcohol stove. The air flowing up through the Progresso can helps in the combustion, especially when you initially start the stove. The real advantage of a wood burner is that (hopefully) you have plenty of fuel available to you where you will be using the stove, thus reducing weight carried and minimizing the need to care about how much fuel you are burning–just burn as much or as little as needed to get the job done.

Make a simple tin-can stove that costs 99 cents, runs for free, and sequesters carbon as you cook. You can build a simple example of an appropriate technology that addresses all these problems: a biomass gasifier camp stove.
There are many designs for efficient camp stoves, and gasification is only one way to boost the efficiency of a cooking fire. This TLUD camp stove works in batches: fill it up with twigs and woody bits, and light it from the top. When a TLUD is dialed in, it’s lovely: a layer of smoke hangs over the coal bed like a fog, and appears imprisoned by a gauntlet of inward-facing flame jets that rush in from the edges of the stove. Most of the wood around my house is snow-soaked and I can attest that wet wood is hard to burn. Making a wood burning stove might be debatable within some groups, for from my reading, it is allowed. In my own experience, I feel that it is essential to teach safety and proper handling for all the permitted fuel types, including and especially wood burning stoves and fires. While a cool DIY project, these stoves are difficult to construct and are prone to injury, especially for the youth. From one perspective, you could argue that this policy is specifically addressing chemical-based stoves and fuels, not wood burning stoves. The wood gas stove in this article is an elegantly simple gasifier design called a TLUD stove (for top-lit updraft), also known as an inverted downdraft stove.

The hot gases rise to the top of the camp stove, where they are met by an inrush of preheated air and, if all goes well, combine completely with this air in a clean secondary burn that consumes the methane, soot, and carbon monoxide produced by the primary combustion. While the stove is gasifying, it’s remarkably clean: there’s little or no smoke and only a faint odor, reminiscent of diesel or creosote. On your first hole, push only the tip of your step drill through the can and into the wood.Remove the can from the backup block and put the drill tip back into the hole you just made. Also known as a wood gas stove, it works with one charge of fuel at a time to produce a hot, smokeless fire.I designed this.
I decided that if this were to be a true DIY project, I would have to use what I had on hand. My troop used to make the Pepsi-can stove, but we switched to making the cat can stove because it was easier to make (just use a single paper hole punch), was less injury prone, and the stoves performed just as well as anything else. After all, an empty coffee can makes a fine wood stove and would even be recommended under Leave No Trace recommendations as you indicate. Younger scouts with less experience should probably start off with canister stoves because it helps build confidence and mastery of techniques. It is not like an alcohol stove or liquid fuel stove where you can more accurately measure burn time based on a measure of fuel. If you’ve ever watched a campfire closely, you’ve seen little jets of smoke erupt from the wood ahead of the flame. And when your camp stove is done gasifying and the flame jets go out, clean charcoal remains in the stove. It easily boils enough water for a small pot of tea or a bowl of noodles, using nothing more than a fist-sized charge of scrap wood. A good gasification stove recreates these conditions reliably, generating smoke and moving air to produce these little fire geysers on demand. Commercial wood gas stoves are fancy, pull air in from the top and blow smoke back through the fire using fans.
Our stove lets air flow from in at the bottom and out at the top, which is either an inverted downdraft or an updraft, depending on how fancy you want to sound. To use this stove, fill it about half full of fine, dry twigs, as thick as a pencil, or finer, and about an inch (25mm) long, laid horizontally.

The heat of the flames at the top vaporizes the wood below the flame, and the open bottom of the stove allows fresh air to rush in and create a strong updraft. All these vents, combined with keeping the cooking pot well above the top of the stove, allows complete combustion. This is totally unlike the average wood fire or can stove, which have to be tended constantly, and which smoke before they get going, while they are burning, and after they burn down. The wood gas stove catches, runs like a blowtorch, then subsides to a cool smolder once the volatile gases have burned off. You are.To make this stove you need some tools and you assemble some parts using bolts and nuts and so on, so it takes some work. Trim back stray pieces of wire and sand down any remaining sharp nubbins.Repeat the process you used above to make the pot supportThe pot support will bear down on the TOP of the screws that hold it, while the stove base will push up on the BOTTOM of the screws there. The stove should not be obviously leaning.One advantage of the hardware cloth is that it has all those little sharp, pointy nubbins, like kitty teeth, and while you have to be careful not to cut yourself or snag clothing on them, they help to hold your pot in place.
This will take around 20 minutes, because once the wood burns down you'll be left with charcoal, which will slowly burn down without smoke. You should see very little wood smoke, and after the first burn, you should notice no smoke from the galvanized metal parts, or smell anything odd.
Keep a pot of water nearby in case you need to quench any flames, or if the stove gets knocked over while burning.As always, watch for problems, take your time. Experiment, but stay away from anything guaranteed to explode in your face and spray you with flaming liquid.Once primed, the stove is ready.
