Yup, had several ideas for the setting, between medieval fantasy, modern, retro, etc. Felt the option chosen would be fun, since as far as I can tell, it hasn't been touched upon. Usually it's the 40s, early 20th century or 19th Century for steampunk/dieselpunk settings. So why not go a bit further in time?

As for Fusion Reactors, sure thing :)
[/quote]They would be big and very expensive to build but in the future it could replace fission-based reactors (not in the military application, though. Unless they get REALLY advanced.)

Also strangely enough this crazy project is actually going to be viable without nuclear weapons to worry about:

Well, without nuclear warheads.
