(2) Paraffin wax and excrement were filled in empty cans, and several metal were planted to generate current. According to Papanek's explanation, the "can radio" made of discarded cans is powered by thermal power. Here, the thermoelectric power refers to the flow of current to the circuit when two different metals are to make a circuit and the temperature of the two joints is changed

1) The exact reason for the creation is not given. By analogy, however, it seems that easy and cheap rocket stoves were made for families who could not install gas stoves.

+) It can be used if there is a dry tree. Because heat is collected inside the stove, the fire can be maintained for a long time. Also, heat does not dissipate because it blocks the wind.
