The method is a curiosity, impractical and useless. It seems almost contrived- requiring a fixed structure to be built in a specific orbit of certain kinds of stars, drinking deep of no less than three separate types of exotic matter, demanding stringent size and mass restrictions. Far easier, then, to take advantage of a different miracle- the true starship. A spindle of conductors and trusses and shipguts, able to push its way up to interstellar speeds. All you need is a little patience.
