I don't usually buy modern model engines, but couldn't resist this solar (low temp differential) twin stirling from Kontax Stirling Engines in the UK. They're expensive compared to the usual Chinese fare, but worth every penny in my opinion; they are of extremely high quality and precision.

Very smooth hypnotic motion ...... soothing!!!
I can certainly understand why this could tempt you to stray from your usual target-line...
What an amazing engine, looks great and runs incredibly smoothly.
Congrats and thanks for sharing!
Very cool Brent.
Thanks for sharing.
They are well worth the extra $. I bought the same one last year and it
ticks over nicely setting on my computer key pad.
I don't have a Kontax Stirling Engine but after reading this thread it is on my list.
Very nice demonstration, Brent. Thank you!
