Abstract
A thermoacoustic electric generator is a device for converting heat into electric power via acoustic power. In this study, we have focused on the method to convert acoustic power into electric power and demonstrated the use of a bi-directional impulse turbine. We manufactured the impulse turbine and connected it to a motor. The turbine is located inside a stainless pipe equipping a speaker. Acoustic power from the speaker, rotational speed of the turbine and electric power from the motor were measured. As a result, the conversion efficiency from acoustic power into electric power was found to be 20%.
