I think external combustion engines are cool
I can watch old steam engines go round and round and round for hours, the "chuff" of expanding steam is like music to the ear.
Stirlings seem to have particular affinity for space or other areas where there's a high heat differential.
BTW, the stirling engine farm that's supposed to be built here in CA is a few miles down the road from me. I believe CMAC posted a picture of it once - I live behind the mountain in the background of that photo.
Better be careful, CMAC. Before you know it you'll be a big fan of technology, especially things like stirling engines which would be very much improved with more money spent on space research...
