Re: Solar powered Gamma Stirling Engine

Hello Krijn, thank you for you comment. Engine and solar mirror mounting are by my own design. Most parts I draw with a CAD (Solid Edge) program to see if and how it works when assembled. Yes, your are right I work as an repair engineer. But building stirling engines is only for fun. The tracking sy...

Re: Solar powered Gamma Stirling Engine

Hi everyone, I would like to show you two more pictures. On the first one you can see the parts of my stirling engine. One the left side you can see the first design of the displacer. The generator was also changed to an stepper motor which generates more power output. The second picture shows a sim...

Re: Solar powered Gamma Stirling Engine

Hello, yes, it drives an alternator, output 10V, so far. On the picture the mirror was not fully aligned and it was cloudy. On sunny days, the mirror is very powerfull and dangerous, I always wear protection goggles. Meanwhile I canged the mirror to a commercially buyed one. It is a bit better than ...

Solar powered Gamma Stirling Engine

Hello, I would like to show you my last stirling engine. At the moment I try to optimize the power output by machining a new displacer. Later I will show some details. The Engine is mounted in the focal point of a parabolic mirror. The mirror follows the Sun automatically. [youtube]https://m.youtube...

Re: "Hi" We are new here!

Hi,

my Name is Marco. I'm from Germany. I have build five stirling engines for the moment and working on number six.

Best regards.
