Hello,

I have been building various Stirling engines for a micro CHP unit fuelled by biogas that I produce myself to support the solar home supply when the sun is not shining.

Now I'm trying out a really almost maintenance-free Stirling concept.

To give you an idea of what this is all about, here is
a video of my thermo-acoustic Stirling engine:

I am talking here about outputs in the range of perhaps sometime 100 to 300 watts (of course then with a completely different effort with higher pressure, temperature and volume).

An introduction to the thermoacoustic Stirling engine can be found here:

Here is an overview of what I am doing and planning:

Thank you very much and I look forward to your opinions, suggestions and proposals!

Ralf
