Really?
Chances are we won't hear anything about it again. The Navy will have nuclear subs with fusion reactors for 20 years before making the technology available for civilian use.
I like JP Aerospace's idea. I don't think it matters that the orbiter is inflatable. In principle at least, as long as they can maintain airfoil geometry there shouldn't be any aerodynamic problems. Of course the energy source will be interesting. Their online article is much shorter on details than even Bussard's paper. But, they work part-time on it like X-Prize teams. Can't expect much.
