They even went so far as to plan the entire device, create design specs and concept art (some of it pictured here), and name it "Project Orion." Now science historian George Dyson has unearthed a bunch of the recently re-classified papers related to Project Orion, which his father Freeman Dyson was involved in, and put them together into a short, entertaining presentation.
