Developing the thermoacoustic Stirling engine to generate power for the home

In this video, I show what further developments I have planned for the thermoacoustic Stirling engine and what fundamentals I have been researching recently in order to achieve a significant increase in performance to reach my goal of going off grid and become energy independent.

To produce our own energy even during periods of low sunshine to support the solar plant, I would like to further develop the thermoacoustic Stirling into a powerful engine.Unlike my kinematic Stirling engines, the thermoacoustic concept promises low-maintenance and long-lasting continuous operation. Therefore, I have recently done a significant amount of fundamental research.This included testing high-pressure-resistant 3D printed parts made from fibre-reinforced engineering filaments for the thermoacoustic gas cycle. The development of a balancing mechanism and the use of linear and stepper motor generators.Improving the heat exchangers and setting up a test bench to advance the development of the thermoacoustic Stirling. Now I can finally start to further develop the engine and make it more powerful.I haven't yet worked on optimising the feedback loop. As a result of my intensive experiments with various filaments, including fibre-reinforced types ( Nylon PA ASA PC/PBT and all also CF reinforced ), I am now able to produce highly complex, high-pressure-resistant 3D printed components very quickly.This allows for the rapid testing of different thermoacoustic geometries and boost pressures of up to 10 bar, as well as various working gases such as helium. This offers great potential for improvement.The design of the feedback loop can greatly influence the flow of thermoacoustic energy back to the core branch and significantly increase performance.Since I want to try out the experimental approach first to get to know the engine better and only later carry out theoretical calculations and simulations with DeltaEC, a well-functioning rapid prototyping workflow with 3D printing is very important in order to obtain results quickly.The conversion of thermoacoustic energy into electrical energy is of central importance and has a significant impact on overall efficiency.In the near future, I will run more comparative tests on different oscillating stepper motors and linear generators. I will also continue testing the bidirectional impulse turbine. The concept of the linear generator is very elegant in itself, and the use of its moving parts for the much needed balancing mass makes it even more attractive.However, this is offset by the huge amount of construction work involved, and by the question of whether it is possible to achieve reasonable efficiency levels with an acceptable level of effort.Using ready-made stepper motors that oscillate at the pivot point of the lever is simpler, and quick replacement makes the concept highly flexible.In extensive tests, I have demonstrated the satisfactory efficiency of stepper motors that are not too small.The engine's output is still so low that rectifying the generated low-voltage alternating current into direct current using a standard bridge rectifier consumes a large proportion of the energy.The use of active or ideal diodes works almost loss-free with very low voltage drop and is more effective, at least at the very low voltages.I have a lot of further developments planned for the thermoacoustic Stirling engine in the near future. Hopefully, some of these will improve the engine's performance.I will report back here soon with my results, and until then, I look forward to hearing your opinions, suggestions and help here on YouTube or Discord.
