Nope, because you can't use PVC for piping steam. You're going to need to use metal pipe. Iron pipe is the cheapest bet but it's such a pain to work with. Personally I'd run copper. I think that's to code for low pressure steam anyways.
Wait, if it's going into space then whos building codes are we using?
Psh. Codes are for wussies.
pump ammonia! Can evaporate at PVC compatible temperature.
A very minor problem with this scheme is the mile thickness insulation needed to not lose much of the sun's heat to space, on the trip back. A 2nd minor problem is the actual pipe section close to the sun.
