Efficient Power Production With Thermoelectric Generating Systems

Thermoelectric generators (TEGs) offer the potential for simple and efficient conversion of heat directly to electricity. However, efficient power conversion systems that incorporate TEGs present an engineering challenge, requiring an overall system design that balances critical trade-offs between TEG performance requirements, thermal management, combustion efficiency, and power conditioning. We propose to develop an innovative power conversion system using a TEG to convert heat from a primary fuel source to electricity. The system will combine state-of-the-art thermoelectric materials with advanced technologies for efficient thermal management, combustion, and power conditioning. In Phase I we will prove the feasibility of our approach by developing an overall system model that includes all critical processes, then selecting system parameters that will optimize the system for maximum overall efficiency. Proof-of-concept tests will demonstrate operation of critical thermal management and combustion technologies. In Phase II we will build, test, and deliver a complete 100 We TEG power system.
