It's not a near-future plausibility Fittingly, the project is part of NIAC (NASA Innovative Advanced Concepts) which is specifically for borderline outlandish, far-future ideas like magnetic sails, space elevators, nuclear propulsion, a "Lunar Crater Radio Telescope" and many other somewhat crazy ideas.
