Next step to the completely 3D printed engine : The membrane power unit

I show how to make a membrane power unit to further simplify the thermoacoustic Stirling engine for complete 3D printing it to generate cheap energy for everyone.

Thanks to Baptiste (alias Olympio) we now have a Discord server: https://discord.com/invite/TDABS5z2mT
It would be very nice if we could discuss there everything about Stirling engines, 3D printing and more, thank you very much Baptiste.
The thermoacoustic Stirling engine uses only sound waves for its energy generation.
As it is externally heated, any heat source can be used to operate it, and it has no moving mechanical parts.
This makes the engine highly reliable and almost completely free from wear and it is perfect for building yourself using a simple 3D printer.
If you’re interested in some basic information about how the thermoacoustic Stirling engine works and how it’s built, check out my YouTube channel, ‘Myengines’ .
Here, in a comprehensive three-part series and many more videos, I describe all the components in detail, including a link to download all the construction plans and 3D models.
You might even be interested in being part of the development process.
Any help is welcome on our Discord server, in the comments, and on our own little forum and development blog website www.ownenergy.org too.
Over the past few weeks, many contributors have developed fantastic new approaches to manufacturing all components using a 3D printer.
It now even seems possible to 3D-print the heating unit yourself from ceramic at a relatively low cost, rather than ordering it from a 3D printing service made from metal or ceramic.
The thermoacoustic machine can operate as a heat pump without any mechanical components and is set to transform heat pump technology in the future.
The design of the electricity generation system is therefore of crucial importance for the quality and long-term reliability of the thermoacoustic engine.
To avoid the problems and complexity of using pistons entirely, a membrane or diaphragm can be used instead.
Do you know of any even better options for manufacturing a membrane or a diaphragm?
As you can see, development of the thermoacoustic engine is progressing well.
As always, I’m really looking forward to your feedback, ideas, and suggestions in the comments, on www.ownenergy.org and on Discord.
If you'd like to support the videos and the project even further, you'll find lots more exclusive content, 3D models, drawings, and files in the members' area and on Patreon.
