Experiments with Peltier modules

  Peltier elements (thermoelectric modules) are widely used in cooling systems. But not many people know about their another characteristics, to generate energy. This laboratory work is devoted to the study of these features.
  50*50 element is placed between two aluminium ingots. The ingots surfaces have been grinded in and greased with thermal paste beforehand. Through-holes were drilled in one of the ingots through which a copper tube was passed for water cooling. The result is in the picture.
 

  Join water up the cooler and supply to Peltier modul, check work of the element. In ten minutes the ingot will be cooled to -10 degrees and in 30 minutes even more. The room temperature is 22 degrees.
 

  Everything works well; I didn’t have any doubts in this. Now switch off power box and solder a 6 volt bulb instead of it; then put the modded device on burner.
