Don, Great thread. Love the idea of the steam engine being refined during Roman era.
For those that say it can't happen blah, blah, blah....ignore them . This is your time line. If they don't like it, they don't have to read it. The pc/laptop (or whatever device they are using to view this site) does afterall have an off button and other sites are availble! As long as you don't include Martians, magic or anything of that ilk, then I'm in.
Keep up the good work.
So, blatantly ignoring of technological and scientific limitations is okay, but calling it magic is not.
I've chosen for the most part to give up reading this and trying to help Don Megel, as he clearly doesn't want any help based on actual knowledge of steam technology, but this idea really deserves better than this kind of kind of "Ignore the critics and listen to the cheering fanboys" attitude.
