  No. Huge power plants are not really suited for lifting them into space.

    They are suited for powering orbital rings though.

      Solar in space would be so much more practical.

        That is only true out till (a litle past) Mars orbit. For deep space mission solars performance in terms of Watts per weight quickly becomes pretty bad. The 1/r^2 drop in solar flux eats your lunch there.

          Fission is fine out there. And DT fusion has no advantage over fission anywhere in space. But I tell you what: let's let space programs pay for fusion, if that's going to be where it gets used. They all seem to have much more immediate tech development needs closer in.
