I've always wondered why isn't someone trying to do a nuclear power generator in outer space. Say, we create a nuclear plant in outer space (maybe around the moon orbit?) where there's no risk of nuclear waste "falling down" to earth if shit happens. Then, said plants are used to generate energy and store it in some high density material (maybe liquid hydrogen?). Finally, some of that energy is spent to "push" the large hydrogen tanks into Earth's orbit so that they fall down into earth. This way the nuclear fusion issues would not matter and this could be scaled a lot. I think that we have all the technical pieces to do this, but it is just a matter of some large company developing the project, even if starting small.
