The travelling wave thermoacoustic refrigerator (TWTR), designed by a research team at Tokai University, consists of three etched stainless steel mesh regenerators installed within the prime mover loop and one in the refrigerator loop.

The team's progress was detailed in a paper, "Performance of a Small Low-Lift Regenerator-based Thermoacoustic Refrigerator
," at the First Pan-American/Iberian Acoustics Meeting in Cancun, Mexico on Dec.
In this project, a Thermoacoustic refrigerator
was manufactured from everyday materials including plexiglass, PVC piping and a loudspeaker.
