Stirling engine with 3d printed half rhombic drive and details of development and optimisation

Hi,
here I show you the development process of the new half rhombic drive Stirling engine.
The original rhombic drive Stirling engine is too complex and expensive to build in a small mini series for the many people who asked for.
To reduce the effort in making a powerful Stirling engine I utilize the extensive use of the 3D printer, the less complex half rhombic drive and more easy to machine heat exchangers.


I am as always very pleased for comments, suggestions and criticism.


Greetings
Ralf
