Well now, it has come alive again...

About the vibration I don't have any exact data. I do know, however, that the stirling cooler uses CO2 as an intermediate, which is in a thermosyphon around the chamber. This means that the cooled CO2 slowly drops down by gravity (higher density when it's colder), and the slightly warmer CO2 on top is going back to the cooling. This is the reason for the 12 degree slope restriction. I can imagine that an excess of vibration will not help the process. On the other hand, it is (widely?) used in vehicles.... and they all vibrate. Also, in the Past, research has been done about putting a Stirling engine in a car. It's responsiveness kept it from getting any further at the time.
I think that, at the least it will keep running, but the cooling will be worse.

on the PS: last year i bought one from the NL office of Global Cooling (yes, I am in NL too). They do sell it as an "Engineering Sample". If it's still on the website, it should still be available.
It ain't exactly a bargain, though. As I recall, it was about €485 excl. BTW.

I hope this helps...

Hope this helps.
