The Project Orion people had extensive calculations on how to send a city-sized ship to another star on a ~100 years trip with nukes.

It is laser propulsion that is techno-magic. Even today. I won't register on whatever site to read yet another article on that, but I do bet neither the lasers nor the sail on this one could be made today.

Project Orion was believed to work with technology from the fifties too. That makes me confident that we could build one today, if we wanted to.
