I do not own one of these yet. It does require machine work. The manufacturer claims even a small Stirling engine can spin it but not a lot of output. They say it will light one incandescent bulb or several LED lights. Uses the guts from a modern DC motor.
I like the little lifting eyebolt and adjustable base. Oil cups are nice touch to.
I will try to post a link...shipping likely expensive from Germany.
If you follow the link you should see photo of both sides and also what it might look like if you paint it.
