====DIY Thermoelectric Generator====

Thermoelectric systems produce electrical energy out of a heat-source.

   * Used to be made of bimetallic junctions.
   * Are now made of highly doped semiconductors, from bismuth telluride, or lead telluride, or calcium manganese oxide.
   * Electromechanical systems including turbines, such as Stirling engines, are more efficient.
