thermogenerators

[asshole]

Hello everybody

I am in my first year of engineering school in Lille, and for a project I am seriously considering using a thermogenerator in order to use the flame heat to supply electricity to a small engine and also a programmer (not too much complicated).
only here, I have no idea the cost of such a device, and I find that the canvas is quite poor on this subject, so if someone would be extremely kind to inform me it would be very nice.

Thank you

What do you mean by thermogenerator?

To recover the heat from the flames, there are Pelletier-type elements, which convert thermal PDD into electricity, otherwise I only see mechanical systems ...
- stirling or ericson engine
- wind turbine / thermal well, principle of the Nazarre and Michaud towers
- miniaturized steam turbine as in thermal power plants ...

There have already been posts about the Pelletier elements.

It seems to remind me that the yield is very low, around 5%
