Based on the ancient Roman technology of hypocaust, this is before Jesus Christ - Dr. Larry Winiarski in 1980 began to develop this stove or rocket kitchen which won many awards.
I believe that we should all have a small device of this type, because in the event that there is no gas, either because of an earthquake or some other catastrophic event, we have less to cook, to boil water, since with very few resources , with very little firewood, you can make a meal in less than 20 minutes.
To ignite it is quite simple, simply with two paper bags one where the fire comes out and the other below where the air is fed, lights up and the flame is expected to stabilize, we will quickly have a fairly strong and constant flame.
In the loading drum, where we are going to put the fuel, we can put firewood, but you can use cardboard or anything else that is combustible, in a few minutes there will be a call occupying all this outlet diameter.
Normally it is made with structural iron or square iron of 10 x 10 centimeters, the construction is as seen, the loading drum has an angle of 45 degrees with respect to the horizontal or vertical.
You could paint any color, if high-temperature paint is used this kitchen or rocket stove is known in many regions of the world, usually in refugee camps, also used by fishermen, hunters, because they have to use very very little fuel, it is totally convenient to have something like that, some designs are disassembled in this model it is not.
