That's very fast! I've wondered if it would ever be possible to make an all-mechanical MP3 decoder/reproducer using 2400 dpi punched metal cards and mechanical logic gates without electrons flowing.
Yup, CD's, definitely safe, unless you get them out of balance, but even the speed yours is going, I don't think that's an issue.
I'm starting to see a trend with stirlings, seems the higher the running revs the harder to start even when fully heated. Very impressive and simple design.
stirling engines get their power from the difference in temperature of the cold and hot side. Just as the hot side must be kept as hot as possible - the cold side must be kept as cold as possible or efficiency is lowered. If you increase the heat to the hot side, gradually the cold side gets hotter too - and this is unwanted (a bigger heatsink will fix the problem though).
bet justin bieber would sound great on that cd

if you look it up cd's are good for way more 20000rpm is safe that why they have a 32x 48 x and so on

i wouldn't recommend spinning cd's at those speeds, cool vid though

lol, surprises me that it stays in one piece, it doesn't look so solid! Great stuff.

2000rpm is also very fast. I like making stirling engine, check my videos! But My rpms are too far the 2000. My best engine can perfom max 1100rpm.

Usually stirling if at cold end going hot the rpm will drop , on my engine cold side temperature is 55*C

Why *would* there be a drop in speed at high temp?

Exactly. And he has kept heat sinking in mind;
very good heat sink arrangement.
Very impressive results from relatively crude materials.
Home made stirlings are most impressive when they do so much with so little.
Good work, Pak!
