Does deuterium-tritium ("D-T") fusion really have a future? Net energy output is one thing but neutrons are the big problem. The two issues are energy loss and destruction of the container (aka neutron embrittlement). I see ITER plans to handle this with basically a large, thick absorption layer (steel and water). CFS OTOH is looking at molten salt solutions. But these solutions seem to be aimed at the embrittlement issue and not really the energy loss issue.
