10 Years of Development !

I show my complete 10 years of research, development and building of the powerful 300 watts Stirling engine with my self build DIY CNC lathe, milling machine and EDM.

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 rhombic Stirling was the true workhorse of my first ten years in engine development.
Every single part was made in my hobby workshop with the highest possible precision.
As my abilities gradually improved, the engine's power and efficiency steadily increased.
The result is a reliable engine delivering the desired continuous electrical output of 300 watts.
My aim is to cover our own energy demand using self-produced biogas, wood, or any other heat sources to run the engine in a combined heat and power unit.
This way, we want to become independent from energy providers and go off-grid.
I have always been fascinated by the elegant Stirling principle of generating electricity directly from heat.
After building the first model engines in my mini hobby workshop, my machine tools also kept getting bigger.
Soon, the first large Stirling engine was running, still without pressurization and complex heat exchangers.
I was more motivated than ever and tried out many things.
But performance only reached relevant levels once I placed the design on a solid theoretical foundation and found ways to manufacture efficient heat exchangers for up to 10 bar of pressurization.
The rise of easy-to-use microcontrollers allowed for the monitoring of all operating parameters, and I could watch and control the hours-long test runs over the net.
A real-time PV diagram and my self built pulse electrical discharge machine are among my personal highlights here.
After years of optimization and further development, the Stirling engine finally delivered the desired 300 watts of electrical power, which, combined with the solar plant, was enough for our own needs.
You can follow almost the entire development spanning over ten years here on my YouTube channel, My Engines.
After long considerations and discussions – especially here on YouTube – I decided on the most radical alternative: the thermoacoustic Stirling engine.
It can operate almost wear-free and can be built inexpensively thanks to its simple design.
We welcome anyone who wants to help further develop the thermoacoustic engine.
All plans and build instructions are open source and absolutely free; you can find the links in the video description.
As always, I look forward to your ideas, suggestions, and feedback in the comments, on Discord, or on www.ownenergy.org.
If you want to support the project even further, a membership on Patreon or YouTube helps a lot.
Every cent from this is invested into the development of the open-source thermoacoustic Stirling engine.

Thank you for your interest!
