I know that I have already posted the weekly Prepper Ping, but this was such a GOOD idea that I just had to give it it’s own thread.
Do I smell something cooking?
Oh, yeah, it’s a lawsuit (BOOM!).

Hold muh beer.....
The whole point of a “rocket stove” is that the chimney is highly insulated and provides a very high draft...
I don’t see a chimney here, much less an insulated high temperature chimney to provide the high draft necessary for the efficient burning of a “rocket stove”.
The Heineken mini keg also makes a great rocket stove, you also get a mini keg of beer.
Other labels also use the mini keg, but I’m not sure which.
The integrated handle on the ammo box is a clear advantage here.
I used to futz around with these as a kid, and picked up a few useful pointers.
1) There is still a lot of native coal in the US, and a lot of states have outcroppings of it where you can just help yourself. Almost nobody looks for it or imagines that it is useful, but if you know where some is, it can save a lot of wood chopping.
2) A cheap set of bellows can get your fire hot and ready much quicker, especially with sub-optimal fuel. They are commonly sold as home fireplace decorations, but never used by most people, yet they work.
3) Always keep a squirt gun handy to cool a fire that is too hot.
4) Fires produce three kinds of useful heat. Convection heat from hot air, which is fast; Conduction heat in things that conduct heat, like metal and liquids, which is somewhat slower; and Infrared heat given off by conductors, which can last for hours. If fuel is scarce, it is important to remember and try to use all three.
Most Americans aren’t too familiar with using Infrared heat to heat an area, but the concept is an old one, and widely used where fuel is scarce. On the large scale, it is used in “oven stoves” or “tile stoves”. (great web page, btw, with lots nice pretty pictures):

Most people don’t want to lug around stone blocks to absorb the heat of their fire and give it off as Infrared, however, but there is an easy solution: It works just as well if you use sand or powder from these high energy density stones.
In order of energy density, from high to low, is gypsum, soapstone, basalt, marble, limestone, sandstone and granite.
So bottom line, instead of using just sand as insulation for your oven, use common, inexpensive gypsum powder, that can be found in any garden store. It will absorb lots of heat, acting like a good insulator, and then give off Infrared to heat the area around it for a long time.
A small amount of fuel can do a lot if you don’t waste it.
Ping!
I made some alcohol stoves from soda (beer) cans that work great. There are a lot of great designs on the Internet.
.
Very clever!
Excellent idea. Thanks for posting!
I took the lazy way out and bought a rocket stove long ago. However, I only have one and more will be needed if TSHTF.
These things would also be great for barter if/when the time comes.
Rocket stoves can get VERY hot, especially if someone uses coal or charcoal. Stove pipe is designed to stand up to high temperature, but I’m wondering about the coffee can. Have you used yours enough to know how well it holds up?
Great article.
A clandestine purchase of mine a couple of months back. (The wife doesn't know)
