My homemade thermoacoustic Stirling engine has to produce enough energy from self-generated biogas to make us, along with our solar power plant, independent of energy suppliers.
To achieve faster and better engine development, I would like to start this as an open-source project together with you.
For this, I will show here now all the dimensions and the entire structure of the thermoacoustic engine in detail.
The idea is to develop a simple, reliable, and efficient power plant that anyone can build with basic tools.
For a long time, I have been producing my own energy, using my conventional Stirling engines and self-generated biogas.
However, my mechanical Stirling engines are too difficult, complicated, maintenance-intensive and therefore too expensive.
The elegant concept of the thermoacoustic motor requires no moving parts except for energy extraction and is therefore ideal for a simple and reliable DIY mini power plant that anyone can build.
The underlying thermoacoustic theory is quite complex, and optimization with DeltaEC and Computational Fluid Dynamics (CFD) requires a great deal of training or experience in this field.
To enable everyone to participate in developing the thermoacoustic Stirling engine, I will describe all the dimensions and the exact construction process here.
There is still a lot of potential here, and optimization with DeltaEC and CFD, together with pressure charging, promises a very big increase in performance.
The thermoacoustic Stirling engine consists of the thermoacoustic core, the feedback loop and the power extraction unit.
It is the heart of the engine in which the thermoacoustic effect is generated.
The core consists of the regenerator, heater, main cooler, secondary cooler and the thermal buffer tube.
Later, improved versions should be printed by 3D printing companies using metal or ceramic.
Nowadays, this is no longer that expensive and allows anyone to build their own engine.
It also allows for much better heat exchanger geometries, and the burner can be integrated into the heater, for example.
The regenerator is the most important component in which the thermoacoustic cycle takes place.
The heater provides heat energy to the hot end of the regenerator through the working gas.
I operate the burner with self-generated biogas, but of course any other heat source can also be used with a suitable burner and heater.
The thermoacoustic Stirling engine has two coolers.
The main cooler cools the cold side of the regenerator through the working gas, while the secondary cooler ensures that the subsequent feedback loop and the power extraction unit do not become too hot.
With good water cooling, the coolers could also be made from self-printed FDM plastic parts.
Special heat-conducting plastic filament or copper wires or similar materials glued into the cooler, which is printed from more temperature-resistant plastic, is the easiest way to build the cooler of your own.
The thermal buffer tube, or thermal relaxation tube, insulates the heater of the secondary cooler and transmits the acoustic power out of the hot zone.
I hope you have gained an impression of how the thermoacoustic core works and have lots of suggestions and ideas about it.
Fortunately, 3D printing of metal or ceramics is no longer unaffordable expensive.
Since the tolerances are not that precise, it is also possible to print plastic-metal filaments on your own FDM printer and then bake them, which is probably the most cost-effective solution.
Despite its simple design based on just a few basic parameters, the engine already produces quite high performance.
I am very interested to hear your opinions and ideas.
If you would like to support me and the project further, you will find many more exclusive content, 3D models, drawings, and files in the members' area and on Patreon.

Thank you very much for your interest, and I look forward to your comments and ideas!
