  5. 4. Thermoelectric properties of conducting polymers

    Författare :Olga Bubnova; Xavier Crispin; Magnus Berggren; Alan Kaiser; Linköpings universitet; []
    Nyckelord :Thermoelectric generation; Seebeck coefficient; conducting polymers; thermoelectric efficiency.;

    Sammanfattning : According to different sources, from forty to sixty percent of the overall energy generated in the world today is squandered in waste heat. The existing energy conversion technologies are either close to their efficiency limits or too costly to justify their implementation. LÄS MER

  7. 5. Energy Harvesting for Wireless and Less-Wired Sensors in Gas Turbines

    Författare :Elof Köhler; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; coupled harvester; piezoelectric harvester; piezoelectric; Energy harvester; thermoelectric harvester; harsh environment; thermoelectric; self-tuning;

    Sammanfattning : Four types of energy harvesters aimed for gas turbine applications were developed during this thesis. The unique gas turbine environment shaped the design- and material choices. A semiconductor thermoelectric harvester was built for a location in the gas turbine with active cooling at 600°C, with 800°C wall temperature. LÄS MER
