行波热声热机已经被证明可以在不使用运动部件的情况下高效地将高温热量转换为声能。电动线性交流发电机和压缩机已经证明了高的声电转换效率以及长的免维护寿命。通过优化一个小规模的行波热声发动机与电动线性交流发电机一起使用，我们已经创建了一个行波热声发电机;一个功率转换系统，适合于苛刻的应用，如航天器上的发电。
Traveling-wave thermoacoustic heat engines have been demonstrated to convert high-temperature heat to acoustic power with high efficiency without using moving parts. Electrodynamic linear alternators and compressors have demonstrated high acoustic-to-electric transduction efficiency as well as long maintenance-free lifetimes. By optimizing a small-scale traveling-wave thermoacoustic engine for use with an electrodynamic linear alternator, we have created a traveling-wave thermoacoustic electric generator; a power conversion system suitable for demanding applications such as electricity generation aboard spacecraft.
