Cheap electricity with a 3D printed acoustic Stirling engine for everyone

In this video, I show my attempts to build a powerful thermoacoustic Stirling engine using simple techniques such as 3D printing.

It would be very nice if we could discuss there everything about Stirling engines, 3D printing and more, thank you very much Baptiste.
The reproduction of the Stirling engine should be easy for anyone to build and provide cheap energy to become off-grid.
To this purpose, I am conducting various experiments to test if modern, partially fibre-reinforced high-performance filaments are strong enough for real engine parts.
Since 3D printing first appeared on the market, I have been using this technology to manufacture parts for my engines.
I generate our own electricity and heat using self-produced Biogas with my homemade engines to support the solar plant during periods of low sunshine.
My goal is to develop an engine that can be rebuilt by anyone at low cost as some Kind of an open-source project, without the need for expensive machinery.
3D printing technology is ideal for the rapid development and cost-effective production of innovative engine components.
Thanks to the development of high-performance technical printing materials and printers with high nozzle temperatures, I now use 3D-printed parts for all components except those in the heater's high-temperature range.
The strength of modern, often fiber-reinforced printing materials is truly impressive.
I have optimized my workflow with various materials so that I can quickly and reliably produce functional components with relatively thin wall thicknesses and a compressive strength of up to 12 bar or 175 psi.
From the sketch to the 3D model and the slicing to 3D printing, it's only a short step, and in most cases you can produce a high-quality, inexpensive component within an evening.
With 3D printing, it would be possible for anyone to print the necessary parts themselves or have them printed at low cost. The design developed here would be freely available to everyone as a kind of open source.
The new concept of the thermoacoustic Stirling engine has far less moving parts and is very well suited for the use of 3D printed parts.
The thermoacoustic gas cycle itself has not yet been optimized, the heat exchangers are still provisional, and I am still experimenting with turbines, linear generators, and rotary generators for the type of energy conversion.
Pressure charging and the use of helium as a working gas would then be the next steps in the quest for more power.
I need all the support I can get for this project, whether that's suggestions and help in the comments, or any other knowledge or talents you can offer.
I have now also set up a Patreon account. If you would like to support me, this is the best way to do so!
Your support through Patreon or a channel membership could speed up and improve development. I invest every cent I get into the project.
As always, I welcome criticism, suggestions, and help in the comments here on YouTube or on Discord.
Thank you very much for your interest.
