Back to the point about solar sails, I should also point out that they can be useful to add a single sail as the Last engine on a design with normal engines, because often they will have enough movement points to give the ship the same final speed as another regular engine (depending on how the numbers round out), but they use no supplies, and actually generate them, so they can increase the range of some designs that way.

That is correct, and nice sometimes. The problem with all of the different engine types is, you need a couple of minutes to find out the optimal engine configuration (put engines together, replace one, two, with sails, next try with a mix of efficient eng. etc.). A kind of background calculator would be nice, mmh?
