Instructions on building a small coffee-cup Stirling engine?

[stuffandthings]

Could someone direct me to instructions on building a small Stirling engine?
It must be able to run on a 100^o F temperature differential, and it must be able to fit in a 3 x 4 inch oval opening.

Thanks.

Run a youtube search. I think "myfordboy" has some cool howto video for a coffee cup powered motor. I think friction would be your most important enemy when building very small. Cheers
