In this research, our interests focused on the thermoacoustic prime mover to recover the waste heat and effective utilization of it. The advantages of this prime mover are the flexibility for various heat sources as an external engine and a possibility as the cost effective system due to simple structure. To improve the total thermal efficiency, various efforts have been made experimentally to grasp the optimization of stack structure which plays an important role to energy conversion. Finally, discussions on the future application of prime mover aiming to utilize the waste energy of exhaust gas are made and, by installing a membrane of natural rubber inside the tube, the acoustic intensity has increased by 20%.
