The Pint Size BinchoCan Stove
This design is nearly the same as our Binchotan Stove that used the coffee can and terra cotta flower pot: www.youtube.com I had been trying to think of a way to make a version without the fragile flower pot and still maintain the all important concept of preheating the intake air inside of the double wall construction before it enters the combustion chamber. Receintly, Hiram Cook found a way to seat an 18 oz soup can into a quart paint can. This was the solution needed. Thank you Hiram! www.youtube.com The cans I have used are of a much smaller size here. Having the holes near the top of the paint can allows the air to flow downward inside of the double wall cunstruction super heating it before it enters the cumbustion chamber. This creates a much higher effeciency that produces more heat energy from a smaller amount of wood.

The Truth About Pots part of the Troop 73 Alcohol Stove Project
The specifications for our cooking pots: Minimum capacity of 500 ml Lightest weight Good heat conductor Fits easily into backpack pockets Stores the stove, windscreen, and fuel inside Reasonably sturdy There is no single pot that is best at every specification, so we began looking for the best compromise among all of the pots we looked at. Pot Weight Comparisons Fosters beer can 27 grams Heineken beer can 29 grams Grease pot 67 grams Antigravity Gear pot 71 grams Snow Peak pot 80 grams Coffee can 92 grams Evernew pot 140 grams WIDE pots with small air space between water level and lid are known to conduct heat best and bring water to a boil fastest. Even though they are the best heat conductors and boil the fastest, for out purposes they are heavier and dont fit into the backpack as well as other pots. Fosters beer can is the lightest in weight by 2 grams. However the Fosters can is made from thinner material, and the sidewalls do not withstand any outside pressure. Heineken keg cans are more rigid than other aluminum drink cans because of thicker material in the sidewalls. Also the embossed rings, and outwardly curved sidewalls add considerable strength compared to other cans. So, even though the Heineken can is the worst heat conductor due to its verticle structure, its the lightest weight pot for its strength, and fits into our backpack. All modern backpacks have several pockets shaped and designed to hold the Nalgene water bottle. The shape of the Heineken can allows ...
