Most of the focus has been on the physics portion of the problem (and probably rightfully so), with the physicists waving their hands and saying, "well, the engineers will figure that out". Well, the engineers are struggling.

I used to think that commercially-viable fusion power was attainable, but I am starting to become a skeptic. At least in the ITER configuration. I hope I'm wrong.
You need something to capture the energy of the fast neutrons and keep it in the reaction, right? Easy on the scale of a star, not so easy in a reactor. Or at least this was how it was explained to me in my undergrad Nuke-E courses...
