If You Like The Sound Of A Thermoacoustic Stirling Engine, Check Out These Plans

A maker known as 'My Engines' has open-sourced their thermoacoustic Stirling engine design, sharing 3D models and drawings via Google Drive. Unlike traditional Stirling engines, thermoacoustic engines convert heat into high-amplitude pressure waves with almost no moving parts, making them simple and reliable. The design uses a piston and linear generator for power output and can run on any heat source, including biogas. The build is within reach of home makers, and beginner-friendly demonstrator options are also referenced for those wanting to start smaller.
