More energy with the acoustic Stirling engine?

I show you my improvements to build a powerful thermoacoustic Stirling engine to produce cheap energy and to go off grid. If you want to support me you get access to exclusive content: https://www.patreon.com/c/Stirlingengines https://www.youtube.com/channel/UCie-_1q_BTL_cpPN_6f0gHw/join

It would be very nice if we could discuss there everything about Stirling engines, 3D printing and more, thank you very much Baptiste.
The performance of the thermoacoustic Stirling engine still needs to increase significantly in order to provide meaningful support for our solar power system in winter. To achieve this, I designed a better burner, enlarged coolers and a finer-mesh regenerator.
I hope this will result in a significant increase in performance and bring me closer to my goal of 300 watts of continuous power, as with my kinematic Stirling engines. For months, I have been working with the thermoacoustic Stirling engine, trying to increase its performance.
I have recently improved my construction techniques and can now manufacture almost all components, except for the hot part of the heater, from 3D printed parts. Modern engineering filaments and post-treatment with annealing and coating with Dichtol make the parts durable and suitable for use at up to 12 bar or 175 psi overpressure.My kinematic Stirling engines also had very low power output at the beginning.
Once they are ready for pressure charging, their performance will improve significantly.
I am still a long way from being able to optimize the thermoacoustic gas cycle theoretically, but I have now started experimenting with DeltaEC in a virtual machine.
After heating the heater for a long time using only a soldering torch, I have finally built a very simple but practical ring burner.
The old coolers are only half as long as the heater, so I am now trying longer coolers with more than double the heat transfer surface area and a significantly higher cooling water flow rate.
The new regenerator now consists of 100 mesh instead of 40 mesh stainless steel wire mesh, and I had the opportunity to cut the discs on a laser, which was very convenient.
I experimented with many things.
The bidirectional impulse turbine ran quite fast, but it would be impossible to power even my smallest generator.
Finally, the performance was satisfactory, and the improvements paid off.
I'm going to do a few experiments and maybe consider using a very lightweight plastic piston without balancing.
This brings me back to the linear generator, which is eventually going to be used anyway.
To keep friction losses and effort to a minimum, a lightweight piston with relatively small magnets without balancing would be ideal.
Would a flat design have advantages over a radial linear generator in this case?
The engine is now at a stage of development where I am seriously planning its pressure charging.
This enables a significant increase in performance.
To do this, the crankcase must be closed and the engine can no longer be started by hand.
The most elegant solution would be to start the engine electrically using the generator.
