It's a scheme based on rotating magnetic field drive (RMF) of field reversed configurations. The claim is that they can preferentially accelerate and recover energy from 3He ions, greatly reducing DD fusion and associated neutrons. I question the recovery part (how is the entropy that is introduced by ion-ion collisions removed?), but do not have the expertise to fully evaluate the claim. In any case, it certainly cannot be ready next year, and would require large amounts of 3He.
