>>13912969I assume it's more on-topic than the first reply to the thread. But the ancient usage of steam is not something I know much about I'm not an expert on that but I do know I saw some documentary once about some ancient invention that uses steam or something like that, and I don't remember much more about it than that. At least I'm giving your thread a bump even though my content is minimal it keeps your thread at the top of the catalog until somebody who has something to contribute sees it.
