it's the same diploma I had at the time, well! excellent practicality; =)
otherwise peltier, that's what I ordered in Canada (we do not find in France!):
is installed on a woodstove (for example, or exhaust tube hot fumes), when it is hot on the base (hot part down) and cold on the radiator (cold part at the top), the module makes the electricity and power a small electric motor that ventilates the hot air in the room, to convect the hot air by convection.
we can also imagine a turbo air intake of the stove that puts the system in turbo mode when it is hot, or a portable phone charging system, etc., or even a led lamp: the advantage c is that we can even move with the bidule when it is hot, the difference of T ° C remains a long time, it is a certain advantage of the difference of T ° C in my opinion;

the electric effect is as follows:
