This appears to be merely a mag-sail, but used as a radiation shield. It seems to be in every way inferior to the m2p2 concept, which uses a mini-magnetosphere

This appears to be merely a mag-sail, but used as a radiation shield. It seems to be in every way inferior to the m2p2 concept, which uses a mini-magnetosphere (instead of just a magnetic field) for the same purpose [1]. The advantage being that we could build and field such systems using existing technology at reasonable cost. 1: http://earthweb.ess.washington.edu/space/M2P2/rad.shielding.pdf http://earthweb.ess.washington.edu/space/M2P2/rad.shielding....
