To be fair, there's definitely some good to be had with putting solar stations into orbit. Remember, he has that one week limit between launches. Reactors require maintenance, plus they're pretty damn heavy. I would agree with the radiators, but then again I have no idea if he needed them or not, so eh. Reading the wiki would have helped him. In the end, his handling wasn't all that bad, aside from failing to actually read the documentation available to him
