Week 2 : Thermoelectric Generator

Objectives: 
To buy the main component for the project.

Analysis/Discussion:

The first component that need to have is the heart of the projects that is the thermoelectric. Today i have purchase Peltier module TEC1-12708 from electronic store in Kuala Lumpur and Seebeck module TEG2-07025HT-SS from http://tecteg.com.

Description of Seebeck module TEG2-07025HT-SS from http://tecteg.com.

"TEG2-07025HT-SS is a unique hybrid module. As long as a DT is applied to the module surfaces DC current will be generated. The module incorporates several unique engineered processes that allow it to withstand temperatures up to 190°C (374°F) hot side. The P and N elements incorporated in this module offer the greatest heat transfer capability in a 40 x 40 mm configuration, resulting in the highest potential power densities. The TEG2-07025HT-SS is ideally suited for liquid to liquid applications. It can be specified in both ceramic or Graphite covered. Graphite sheet offers exceptional thermal transfer ability, require no thermal grease and will not degrade over the life of the TEG module."

Conclusion:

Peltier module and Seebeck module is buying to make comparison the output between them
