Perhaps cold fusion is something we only need to figure out when everyone has their own spaceship.

I think cold fusion is a false lead.
We should be focusing on how to better contain already-existing hot fusion.
This has nothing to do with fusion. It just uses some of the same tools that hot fusion researchers use.
Like I've said before. This has nothing to do with fusion, cold or otherwise. It's focused millimeter microwaves used to drill very deep holes.
Sad to say, from my research, I'm forced to conclude that with foreseeable technology spaceships will be restricted to a minimium size. Radiation is space is a real hazard beyond low earth orbit. To minimimize the health risks a lot of shielding will be required. By a lot I mean...bunchatons, like hollow out an asteroid and live inside it.
Cold fusion. They call it Low Energy Nuclear Reactions (LERN) for short now after that debacle a couple of decades back. There are some technologies that can achieve it at low levels. I know NASA built some rig that could do it to a degree. There are also some theoretical models that report on using lasers to achieve fusion, but I don't know if it's in the experimental stages yet.
