[My Engines] has been doing some sterling work on Stirling engines for some years now. Their thermoacoustic engine is now finally far enough along to open-source<\/a>, so the magic of collaboration can speed technological advancement.<\/p>\n

You\u2019ve probably heard of Stirling Engines, but what\u2019s this \u201cthermoacoustic\u201d business? Hot sound? Well, that\u2019s the translation, and it\u2019s not a bad starting point for understanding what\u2019s going on: the engine converts heat into high-amplitude sound waves \u2014 that is, waves of pressure \u2014 which means the engine itself has no moving parts. Well, almost. Obviously moving parts are required to get power out. In [My Engines] case he\u2019s using a piston and linear generator, but otherwise it makes for a very simple, very reliable engine that can be fueled by any available source of heat. Say like burning methane from [My Engines]\u2019s home biogas plant.<\/a><\/p>\n

[My Engines] promises more videos to help you understand the construction in a way his previous videos might not detail, and has put 3D models and drawings at a public Google Drive<\/a>. There\u2019s also a Discord you can join, because apparently that\u2019s the only way to communicate about projects these days.<\/p>\n

The whole build is very much within range of a home maker, though there\u2019s a lot more to it than the toy Stirling engines you may have made out of tin cans<\/a> back in the day. If you want to play with thermoacoustics but [My Engines]\u2019s design seems like a little much to get started with, you can make a demonstrator with some steel wool and a test tube<\/a>. Be careful, though: model engines can be an addictive hobby.<\/p><\/p>\n","protected":false},"excerpt":{"rendered":"[My Engines] has been doing some sterling work on Stirling engines for some years now.
